Which type of internet connection is terminated at a local switching center and requires a different media type between the switching center and the end customer? ​ Fiber ​ DSL ​ ISDN ​ Cable

(Incorrect) Explanation OBJ-2.7: DSL is a technology used to transmit multimedia traffic at high-bit rates over twisted-pair copper wire (over ordinary telephone lines). This allows the telecommunications company to connect a user's home to the local switching center using normal telephone lines, then connect that local switching center (using a DSLAM to multiplex the connections) to the central office over a single high-speed cable (such as a fiber connection).

Your email client has been acting strangely recently. Every time you open an email with an image embedded within it, the image is not displayed on your screen. Which of the following is the MOST likely cause of this issue? ​ Incorrect email settings in the antivirus software ​ Incorrect settings in your email proxy server ​ Incorrect settings in your web browser's trusted site configuration ​ Incorrect security settings in the email client ​ Incorrect settings in the host-based firewall

ANSWER IS D OBJ-3.10: The BEST solution would be to use a wireless print server to connect the printer to it using USB. This wireless print server can then receive the print jobs directly from all of the network users. It is not recommended that the technician create a share on the manager's computer or set the printer configuration to the manager's IP address since all print jobs would fail anytime the manager shut down or restarted their computer. Using a USB drive to transfer the files to the manager's computer each time someone wanted to print is also not a good solution since this is difficult for the users and will be disrupting the manager's work every time someone needed to print something.

A user called the help desk to complain about an issue with their laptop's keyboard. Every time they type a word like "help" or "none," it is displaying as something cryptic like "he3p" or "n6ne". Which of the following is the MOST likely cause of this issue with the laptop keyboard? ​ The NumLock has been enabled for the laptop ​ The keyboard driver needs to be updated ​ The keyboard is faulty and needs to be replaced ​ The keyboard has some crumbs or debris that has fallen under the keys

ANSWER IS A Explanation OBJ-5.5: Most keyboards have a numeric side (numbers only) and an alphanumeric side (numbers and letters and symbols). However, to minimize space usage, companies create some keyboards with the alphanumeric side only. This is quite common in laptops that insist on minimizing space for the sake of portability, as seen on mini-laptops and notebooks. Usually, the alphanumeric side is split into function keys (F1 to F12), followed by numeric keys (0-9) and then alphabetic keys (A-Z). To fix this, the fastest way to do this is to turn off NumLock using your laptop keyboard. If you hit the NumLock key, it will turn off. A light beside the key or on the laptop's top will go off to confirm that the NumLock is disabled.

A technician is troubleshooting an issue with a workstation. The workstation can ping 8.8.8.8 successfully, but it is unable to access Facebook.com. Which internal network server is MOST likely causing these issues? ​ SMTP server ​ DHCP SERVER ​ DNS server ​ FTP server

ANSWER IS C OBJ-2.5: DNS is the domain name service. A DNS server is used to perform name lookups and convert them to valid IP addresses. If a workstation can ping an IP, that indicates the network connection is working. If the workstation cannot access a website using its domain name (like diontraining.com or facebook.com), it indicates a problem might exist with the DNS server.

Which of the following ports should you block at the firewall if you want to prevent a remote login to a server from occurring? ​ 443 ​ 25 ​ 110 ​ 23

23 Explanation OBJ-2.1: Port 23 is used by telnet, which administrators use to connect remotely to a server and issue commands via a command-line interface. Telnet is not commonly used in networks anymore because all of the commands sent back and forth to the server are passed without any encryption or protection. Therefore, telnet is a security risk and has been mostly replaced by SSH (Port 22). Port 25 is used by SMTP, Port 110 is used by POP3, and port 443 is used by HTTPS.

A DHCP Server

DHCP Server is a network server that automatically provides and assigns IP addresses, default gateways, and other network parameters to client devices

As a PC Technician, you are on the road most of the day and use a laptop. When you get back to your office at the end of the day, you want to be able to quickly connect a larger external monitor, keyboard, and mouse to your laptop through a single USB port to perform additional work on the larger screen. Which type of device should you choose to provide all the functionality above? ​ USB 4-port hub ​ Docking station (Incorrect) ​ Port replicator (Correct) ​ Thunderbolt

Explanation A port replicator is a device used to connect multiple peripherals to a laptop quickly. The monitor, printer, network, keyboard, and mouse are permanently plugged into the port replicator, connecting to the laptop via the USB port. A docking station provides additional capability to a laptop and further expansion of its capabilities. For example, a docking station can provide power, external monitor connections, additional storage, and even CD/DVD drives in them. A USB 4-port hub will only provide USB expansion (which doesn't support a monitor by default) and is therefore not a possible right answer to this question.

Jason is attending the CompTIA Partner's Summit convention this year. While at the conference, Jason will need to ensure his smartphone has enough battery power to last the entire day without having to recharge it since it is hard to find an available electrical outlet in the conference rooms. Jason needs to ensure his smartphone is always available for use in order to receive updates from his team back home, as well. Which of the following would you recommend Jason use to ensure he can use the phone all day without his smartphone running out of power? ​ Set the smartphone to airplane mode ​ Bring a power strip so that more than one person can use an electrical wall outlet ​ Use a wireless charging pad ​ Use a smartphone case with a built-in battery

Explanation OBJ-1.5: To extend the device's battery life and enable Jason to use it continuously throughout the day, it is recommended that he use a smartphone case with a built-in battery. These cases can provide enough battery power for an additional 8-12 hours of use. A wireless charging pad is a bad choice since you cannot easily use the phone while it is on the charger, and the charger still needs a power source (like an outlet). A power strip would also be a poor choice because it assumes there is a wall outlet available. Airplane mode is a bad choice because it may reduce the power needed (and therefore extends the battery life), but it also will prevent any connectivity over the cellular network.

You have just set up an FTP server to allow users to download the new open-source application your company is releasing. Which port should be opened to allow users to connect to this server? ​ 23 ​ 25 (Incorrect) ​ 22 ​ 21

The device should log the event, but it should not take any action to stop it. Which of the following devices would be the BEST for you to select? ​ IPS (Incorrect) ​ Proxy server ​ Authentication server ​ IDS (Correct)

Explanation OBJ-2.5: An intrusion detection system is a device or software application that monitors a network or system for malicious activity or policy violations. Any malicious activity or violation is typically reported to an administrator or collected centrally using a security information and event management system. Unlike an IPS, which can stop malicious activity or policy violations, an IDS can only log these issues and not stop them.

You are trying to select the best device to install to proactively stop outside attackers from reaching your internal network. Which of the following devices would be the BEST for you to select? ​ Proxy server ​ IPS (Correct) ​ Syslog server ​ IDS

Explanation OBJ-2.5: An intrusion prevention system (IPS) is a form of network security that detects and prevents identified threats. Intrusion prevention systems continuously monitor your network, looking for possible malicious incidents, and capturing information about them. An IPS can block malicious network traffic, unlike an IDS, which can only log them.

Which of the following is a public IP address? ​ 10.3.2.1 ​ 169.254.2.1 ​ 8.4.2.1 (Correct) ​ 192.168.2.1 (Incorrect)

Explanation OBJ-2.6: The IP address of 8.4.2.1 is public and is therefore routable. The IP address of 10.3.2.1 is a private Class A IP address, and therefore non-routable. The IP address of 192.168.2.1 is a private Class C IP address, and therefore non-routable. The IP address of 169.254.2.1 is an APIPA (Automatic Private IP Address), and therefore non-routable.

You work as a computer technician for a production company that travels worldwide while filming and editing music videos. Due to the nature of video editing, you will be building a video production workstation for the company that will have the maximum amount of RAM, an 8-core CPU, a dedicated GPU, and a redundant array of solid-state devices for storage. You are now determining which power supply to install in the system. What is the MOST important characteristic to consider when choosing a power supply? ​ Efficiency rating ​ Amperage of 12V rail ​ Number of SATA connectors ​ Input voltage

Explanation OBJ-3.7: This question provides you with many details, but the key phrase in finding the answer is in the first sentence. This computer will be traveling worldwide, and the most important consideration will be the input voltage. If you choose a 120-volt power supply, it would be destroyed if plugged into a 240-volt outlet (commonly used outside the United States). Conversely, if you use a 240-volt power supply and plug it into a 120-volt outlet, it will not function due to the lower voltage. Therefore, you need to pick a power supply with dual voltage selection capability for maximum compatibility worldwide.

You just printed a new sign for your office using thick cardstock paper with your network printer. Unfortunately, when you pick up the cardstock from the laser printer's output tray, the printed image smears across the paper. Attempting to troubleshooting this problem, you decide to print another sign using regular printer paper and determine that the image does not smear when touched on the regular printer paper. Which of the following would be the NEXT step to perform in your troubleshooting efforts? ​ Replace the toner cartridge in the printer ​ Increase the temperature of the fuser element ​ Change the feed rate of the paper ​ Clean the printer's transfer roller

Increase the temperature of the fuser element (Correct) Explanation OBJ-5.6: When printing with a laser printer, the paper passes through rollers in the fuser assembly, where temperatures up to 801 F (427 C) and pressure are used to bond the toner to the paper permanently. If you often print with specialty paper (i.e., envelopes, cardstock, & labels), you may want to turn up the fuser temperature on your printer. With thicker paper types, heat does not transfer as easily as it can with standard paper, which means the toner may not bond as well, and the image can be smeared when you touch it.

You are working as a Managed Service Provider for a large chain of doctor's offices. The company is opening a new office downtown. The office needs 2 computers to be installed at the receptionists' desk to schedule appointments, read email, browse the web, and conduct basic word processing tasks. Which of the following type of computers would BEST meet the needs of this doctor's office? ​ CAD workstation ​ Thick client ​ Touch screen kiosk ​ Audio/video editing workstation

OBJ-3.8: A thick client (also called a fat client) is a computer that will perform the bulk of the data processing in client/server applications on the local computer. There is no need for continuous server communications with thick clients as it is mainly communicating archival storage information to the server. The thick client has an operating system and applications installed directly on its own hard drive. Thick clients are considered a standard workstation in most business environments and can support email, web browsing, word processing, and other basic tasks.

A client states that their computer is experiencing slow performance when reading or writing to the hard drive. You have already verified that it is not a system (software) performance issue, and the system is not overheating. Which of the following would be the BEST action to take in attempting to fix this problem? ​ ​ Clean the cooling fans of the system ​ Run the disk repair tool ​ Backup the hard drive

RUN DISK REPAIR TOOL Explanation OBJ-5.3: Slow performance can be a symptom of overheating or other problems. Since we eliminated overheating as the cause, the issue is most likely caused by a file system problem. To fix this problem, you should try running the disk repair tool or run the Disk Defragmenter tool (for non-SSD devices) to optimize the file system and read/write performanc

You are installing some new hard drives in a legacy Novell NetWare server in a closed IPX network. The hard drive has a 4-bit set of jumpers that must be configured to represent the device's ID number (0-15) in the storage device chain. Which of the following types of connectors would you use for data transfer with these hard drives? ​ USB ​ SCSI (Correct) ​ SATA (Incorrect) ​ PATA Explanation

SCSI SKUZZY

DNS (Domain Name System)

The Internet's system for converting alphabetic names into numeric IP addresses.

You see streaks of toner across your papers when you print things using your office's laser printer. What is the MOST likely cause of this problem? ​ Change the feed rate of the paper ​ Clean the printer's transfer roller ​ Increase the temperature of the fuser element ​ Replace the toner cartridge in the printer

answer is B Explanation OBJ-5.6: The transfer roller is one of the most important components inside the printer, as it charges the toner in the drum before it transfers to the paper. If you see streaks of toner on your printouts, this is usually an indication of a dirty transfer roller. Consequently, occasionally cleaning the transfer roller can keep your printed documents clean and streak-free. You may print hundreds or even thousands of pages on your laser printer between toner cartridge changes, so it is prudent to clean the unit whenever you change the toner cartridge to keep used toner from building up and clogging the print mechanism.

The large multi-function printer in your office is shared between 12 people. Unfortunately, it has stopped working, and the technicians have determined it must be replaced. A new printer has been ordered, but it will be 2 weeks until it arrives. The only other printer available in your office is the manager's printer, but it is connected via USB to their workstation. One of the technicians would like to share the manager's printer with the other 12 employees for the next 2 weeks as a temporary workaround. Unfortunately, there are no spare wired network jacks available in the office to connect the printer to the network directly, but there is a wireless access point nearby. Which of the following is the BEST way for the technician to allow the 12 employees to access the manager's printer? ​ Configure a new printer on each user's workstation and point it to the manager's IP address ​ Purchase a portable wireless print server and connect the printer to it using USB ​ Share the printer directly from the manager's computer by creating a share and giving the other employee's access rights to the share ​ Provide a USB thumb drive to each employee so that they can transfer their files to the manager's computer for direct printing

ANSWER is B + OBJ-3.10: The BEST solution would be to use a wireless print server to connect the printer to it using USB. This wireless print server can then receive the print jobs directly from all of the network users. It is not recommended that the technician create a share on the manager's computer or set the printer configuration to the manager's IP address since all print jobs would fail anytime the manager shut down or restarted their computer. Using a USB drive to transfer the files to the manager's computer each time someone wanted to print is also not a good solution since this is difficult for the users and will be disrupting the manager's work every time someone needed to print something.

Which of the following types of connectors are used to terminate a serial cable for an external modem? ​ DB-9 ​ RJ-11 ​ RG-6 ​ RJ-45

ANYTIME ITS A MODEN ITS DB-9 Explanation OBJ-3.2: DB-9 connectors are designed to work with the EIA/TIA 232 serial interface standard, which determined the function of all nine pins as a standard so that multiple companies could design them into their products. DB-9 connectors were commonly used for serial peripheral devices like keyboards, mice, joysticks, and data connectivity. Today, the DB9 has mostly been replaced by more modern interfaces such as USB, PS/2, Firewire, etc. However, there are still many legacy devices that use the DB-9 interface for serial communication.

You are troubleshooting a computer that will not boot. After gathering information from the client about the symptoms they have experienced, you believe the power supply may be faulty. You used a power supply tester to determine if the power supply provides the right amount of output voltage and has determined the power supply is only providing 50% of the voltage that it is supposed to provide to the workstation. What is the next step you should perform according to the CompTIA troubleshooting methodology? ​ Verify full system functionality and, if applicable, implement preventative measures ​ Establish a theory of probable cause (question the obvious) ​ Establish a plan of action to resolve the problem and then implement the solution ​ Identify the problem

Explanation OBJ-5.1: After testing your theory, you will move into the "establish an action plan to resolve the problem and implement the solution" step of the troubleshooting methodology. For the exam, you must be able to list and identify the 6 steps of the CompTIA troubleshooting methodology in order. (1) Identify the problem. (2) Establish a theory of probable cause (question the obvious). (3) Test the theory to determine the cause. (4) Establish a plan of action to resolve the problem and then implement the solution. (5) Verify full system functionality and, if applicable, implement preventative measures. (6) Document findings, actions, and outcomes.

You are attempting to troubleshoot a computer for a user. When you attempt to turn on the computer by pressing the power button, the computer turns on, and the fan spins normally. There is no output displayed on the screen from the PCIe x16 video card. You turn off the computer, remove the processor and the memory, and attempt to power on the computer again. During the boot-up sequence, you do not hear any POST beep codes, but the fans still spin normally. Which of the following is the MOST likely cause of his issue? ​ The power supply's voltage switch is set to 240V but the power outlet is providing 110V ​ The CMOS battery needs to be replaced ​ The power supply wattage is too low for the components in the computer ​ The motherboard has failed and needs to be replaced

Explanation OBJ-5.2: If your computer won't boot, but fans spin continuously, it indicates a problem with the power supply, the motherboard, or overheating could be occurring. When the power supply to your computer fails, it won't start or power-up, but the fans spin (as described in this question). One of the reasons your computer won't boot but the fans spin could be a bad processor or memory chip. To isolate this as a reason, you should remove the processor and memory and then attempt to boot up the computer and listen for a POST beep code. In this case, we could eliminate the motherboard, processor, and memory as the issue's source since no POST beep codes were heard. Based on the symptoms and actions performed, it appears that the power supply is not providing enough wattage to all the components of the computer, which is why the fans are spinning (they use low wattage) while the rest of the system fails to boot.

Your computer keeps losing track of time and the date in the system. Which of the following is MOST likely causing this issue? ​ The CMOS battery is dead and needs to be replaced (Correct) ​ The power supply is faulty ​ The memory is corrupted ​ The motherboard's device drivers need to be updated (Incorrect) the need for a CMOS battery by replacing it with an area of

Explanation OBJ-5.2: Most motherboards (especially older ones) have a small coin-sized battery installed on them to power the CMOS RAM when the computer is powered down. This is where the BIOS settings and date/time are saved when power is removed from a workstation. If a computer continually loses track of the day/time, this is a classic sign that the CMOS battery is dead and needs to be replaced. Please note that some newer motherboards have replaced

A user is complaining that they are hearing a whining noise coming from their workstation. You begin to troubleshoot the issue and determine that it is not an issue with the hard drive but is instead caused by the case fan. Which of the following actions would BEST solve this issue? ​ Spray a little bit of WD-40 into the fan to lubricate it ​ Remove and reseat the case fan ​ Replace the case fan ​ Spray the fan with compressed air to remove any dirt, debris, or dust

Explanation OBJ-5.2: Most workstations have numerous cooling fans installed, including 1 or 2 case fans, a processor fan, and a power supply cooling fan. If you hear a whining or grinding sound from one of these fans, you should replace the fan with a new one, as this is a symptom/sign of impending failure of the cooling fan. If the fan in the power supply is faulty, replace the ENTIRE power supply. You should never attempt to repair or fix a broken power supply or broken power supply cooling fan due to the power supply's high voltage electrical components.

A client reports that their workstation is continually crashing when using certain applications on their Windows system. The system will stop working and display a BSOD error on the screen. Which of the following is the most likely cause of this BSOD error? ​ Failure of the graphics card ​ Failure or corruption of the memory ​ Failure of the power supply ​ Failure of the processor

Explanation OBJ-5.2: The Blue Screen of Death (BSOD) is a "stop screen" that appears when the Windows operating system detects a critical error and literally stops the system so that the error doesn't cause any loss of data. All operating systems have some form of "stop screen," but the Windows version got the name BSOD since it was a screen with a full blue background and white text containing troubleshooting information and error codes. On a Mac (OS X) system, the BSOD is replaced by the "Pinwheel of Death," which is an endlessly spinning mouse pointer displayed on the screen. This usually occurs due to a memory failure or memory corruption in the system.

The video editor at Dion Training has submitted a trouble ticket stating her editing workstation makes a loud clicking noise whenever she is editing videos for an upcoming course. You initially thought the system fans were causing the noise. You have replaced the fans, but the noise continues to be heard when applications are loaded or the videos are being edited. Which of the following actions should you perform NEXT? ​ Replace the hard disk (Incorrect) ​ Perform a full backup of the hard disk (Correct) ​ Scan the system for viruses ​ Perform a System Restore

Explanation OBJ-5.3: The next thing you should do is to perform a full backup of the hard drive. A clicking noise is commonly associated with a hard drive that is about to fail. Therefore, you should first conduct a full backup of the hard drive and then replace the faulty drive with a new hard drive to prevent any data loss from occurring.

Which cloud computing concept is BEST described as focusing on the replacement of physical hardware at a customer's location with cloud-based resources? ​ SaaS ​ IaaS ​ SECaaS ​ PaaS

Iaas Explanation OBJ-4.1: Infrastructure as a Service (Iaas) is focused on moving your servers and computers into the cloud. If you purchase a server in the cloud and then install and manage the operating system and software, this is Iaas.

You are working as a technician for a college. One of the professors has submitted a trouble ticket stating that the projector connected to the workstation in his classroom is too dim. You look at the image being projected on the wall and notice it is dim, but the image appears to be displayed clearly and correctly. What is the FIRST thing you should do to make the image brighter? ​ Update the video driver on the workstation ​ Replace the bulb in the projector ​ Modify the workstation's video resolution ​ Increase the contrast on the projector

Explanation OBJ-5.4: If the image being displayed is dim, this could be an issue with your project's contrast. By increasing the contrast, you can increase the amount of light reflected from an all white image and an all black image. The higher the contrast ratio, the brighter the whites will appear in the image. For example, if you have a projector with a 3000:1 contrast ratio, this means that the white image is 3000 times brighter than the black image. The higher the contrast ratio, the more detail you can see on the projected image, regardless of whether it is numbers, pictures, graphs, text, or video. Contrast is what makes it possible for us to see the subtle shades of colors. If the project supports the contrast or contrast ratio adjustment, you should increase the contrast to brighten the screen's image.

A salesman has been traveling to different businesses all day to give a sales presentation. Each time, he was starts up his laptop and logs into Windows to show his PowerPoint presentation to the customer. During his second appointment, his laptop lost power and shut itself off abruptly. He arrives at his third appointment and plugs in his laptop to recharge it. When he powers on his laptop, he sees a very low-resolution version of his normal desktop. He attempts to change the resolution from 800 x 600 to 1920 x 1080 (his normal resolution) but cannot find it in the Display Settings options inside of Windows. Which of the following could be the cause of this error? ​ Corrupted motherboard firmware ​ Corrupted or missing display driver ​ Graphics card failure ​ Corrupted memory module

Explanation OBJ-5.4: If your display is shown in low resolution (640 x 480 or 800 x 600), but the computer isn't in Safe Mode, it is usually a driver issue. For some reason, the laptop's display driver has become corrupted between the salesman's last appointment and this appointment. Without a valid display driver, Windows will revert to the "Generic VGA" driver, limiting the system's highest resolution to 1024 x 768. To solve this issue, you should reinstall a new display driver for the laptop's appropriate graphics card.

You had just bought a top of the line smartphone 2 months ago. In the last week, though, the smartphone seems to be running slowly. About 3 weeks ago, a new version of the phone's operating system was installed. At first, everything was still working fine, but this week the smartphone is very sluggish. You brought the smartphone back to the store to diagnose the problem. They have run a full set of diagnostics on the smartphone's hardware, but no issues were found to exist with the hardware. What do you think is MOST likely causing the poor performance with this smartphone? ​ The newly installed operating system update is too resource-intensive for this smartphone's hardware ​ A lot of the apps on the device are performing an update based on the newer OS being released ​ The internal storage device of the smartphone is faulty ​ The smartphone was set to airplane mode by mistake

Explanation OBJ-5.5: The most likely cause for the slowdown of this top of the line smartphone is that too many apps are simultaneously trying to perform an update, and it is overwhelming the processor and memory. This commonly occurs within a week or two of a newly installed OS version. For example, if we upgrade from iOS 12 to iOS 13, all of the apps are updated and recoded to support the newer OS version. They are usually released within 1-2 weeks of the newly released version. Since the hardware passed all the diagnostics, the problem cannot be the internal storage. The OS update isn't too resource-intensive since it is only a two-month-old top of the line device.

You are working as a laptop repair technician. You just received a laptop that was reported to have a glass of water spilled on it. You want to examine the components in the laptop to begin troubleshooting it. What are the first steps you should take as part of your troubleshooting process? ​ Remove the external casing of the laptop and document the screw locations ​ Submerge the laptop in a large bowl of rice to fully dry out the inner components ​ Watch a YouTube video for tutorials on how to fix this model of laptop ​ Consult your fellow coworkers for suggestions and advice

Explanation OBJ-5.5: When you are taking apart a laptop, it is important to keep track of each of the screws and the location that they were removed from. Many of the screws may appear to be the same height or width, but they may actually be different. One easy way to keep track of these parts is to create a grid on a sheet of printer paper and place the screws on this makeshift diagram. While the other options may be useful, the question asks you what you should do first to examine the laptop components. To perform that examination, you must remove the external casing and its screws.

Tom, a salesman, is trying to print a 3-page report to the network printer located in the Sales department's office space. He walks over to the printer but doesn't see the pages in the printer's output tray. He checks the on-screen display of the printer, but he doesn't see any errors listed. Tom tries a few more times, but he gets the same results. Frustrated, Tom selects the network printer for the Customer Service department and sends his print job there. He walks over to their offices and finds his 3-page report sitting in that printer's output tray. Tom asks you to help him solve this printing problem. What action should you take FIRST to help solve Tom's problem? ​ Ask one of Tom's co-workers to attempt to print something to the Sales department's printer to verify it is working properly ​ Verify that Tom has been sending the document to the correct network printer's queue (Correct) ​ Login to the network's print server, stop and restart all of the ​ Stop and restart the PC's print spooler service using your administrator account

Explanation OBJ-5.6: The first thing you should do is verify that this problem is not caused by user error. To do this, you should verify which network printer queue Tom had been sending the document to the first few times. You may wish to ask a coworker to print to the Sales department's printer, but that would be your second step AFTER verifying the user was printing to that print queue properly first. Since the print job was successful once Tom switched to another printer, the PC's print spooler worked properly, so you don't need to restart it. It would be best if you did not restart all of the shared printer queues since this would affect all company employees and is not necessary to solve this issue.

Several users from the Sales & Marketing department have called the service desk complaining that they cannot access the internet from their workstations. You arrive at the salesperson's workstation, open the command prompt, and enter the command IPCONFIG. The command returns an IPv4 address of 10.1.2.3, a subnet mask of 255.255.255.0, and a default gateway of 10.1.2.1. You attempt to run the command "ping 8.8.8.8" but get the message "Request timed out" displays four times on the screen. You attempt to ping the IP of the salesperson's workstation sitting next to this workstation and receive four successful replies from the command. You then try to ping the gateway (10.1.2.1) but again receive the message of "Request timed out" on your screen. Which of the following is MOST likely the problem with the salespeople's internet connectivity? ​ The salespeople are getting APIPA addresses from the DHCP server (Incorrect) ​ The wireless access point in the Sales & Marketing department is not working properly ​ The router that connects the Sales & Marketing department to the rest of the company is not functioning properly (Correct) ​ This is a DNS issue since you cannot access the internet

Explanation OBJ-5.7: Since you can ping other workstations within the Sales & Marketing department, but you cannot successfully ping the gateway device (the router), this indicates that the router is non-functioning at this time. If the router is not functioning, the workstations will be unable to access any devices or servers outside of the Sales & Marketing department since the router is necessary to connect them to those devices.

You have just installed a new hard disk drive into your computer, but the motherboard does not recognize it within the BIOS/UEFI. You have verified the drive is properly connected to the motherboard and the power supply with the correct cables, but it still is not recognized. Which of the following actions would BEST solve this problem? ​ Update the firmware of the motherboard ​ Format the new hard drive as NTFS ​ Format the new hard drive as FAT-32 ​ Configure a RAID in the BIOS/UEFI

Explanation UPDATE THE FIRMWARE OF MOTHERBOARD

You are setting up a new wireless network at the local brand of your community's public library. Previously, the library only had a small wired network that relied on statically assigned IP addresses. You just finished installing all of the wireless access points. You configured a server to automatically provide an IP address to wireless clients when connecting to one of the wireless access points. To test the new wireless network, you turn on your wireless adapter on your laptop and connect to the network. Your laptop is automatically assigned an IP address of 192.168.1.12 from the DHCP server, and you can ping the default gateway of 192.168.1.1. You open a web browser and attempt to connect to diontraining.com, but you cannot connect and instead receive an error. You attempt to ping the IP address for the Google DNS server (8.8.8.8) and are successful. Which of the following should you attempt to do NEXT to resolve this issue? ​ Disable the Broadcast SSID option for the wireless access point ​ Verify that the DHCP server is properly configured to provide the IP address of a DNS server ​ Disable the Windows Firewall to ensure it isn't blocking your access to the website ​ Enable DHCP inside of your laptop's network adapter settings

Explanation CORRECT B OBJ-5.7: Since you are already connected to the wireless network and can ping the gateway using its IP address, you already know the SSID and DHCP are properly configured (therefore, you should not select these options). It is a poor security practice to disable the firewall, so it is not recommended that you choose this option. Since we cannot access a website using its domain name (diontraining.com), we can successfully ping a remote server using its IP address (8.8.8.8). This indicates that your laptop has not been properly assigned a DNS server to use by the DHCP server. Therefore, you need to verify the DHCP server is properly configured to provide the IP address of a DNS server to the clients when it assigned them their IP address configuration information.
