Someone left a flash drive on the computer. ​ b. Someone cleared CMOS. ​ c. The computer's hard drive has failed. ​ d. The CMOS boot order is incorrect.

a. Someone left a flash drive on the computer. Someone left a flash drive in the computer. This is a classic example of "Keep It Simple." There could be an argument for ANY of these answers, but CompTIA wants you to look for the easy answer first. People are notorious for leaving USB drives, and other removable media in computers. If the boot order looks for one of these drives, the computer will try to boot from it. Granted, on more modern PCs you usually get a "Press a key to boot from removable drive" type of error, but not all computers do this.

A user has just dropped off his laptop reporting that the screen is very dim and it's difficult to make out the icons on the desktop. When you plug in an external monitor to the system, it brings up the desktop perfectly. Which of the following needs to be replaced? ​ a. The LCD inverter ​ b. The LCD panel ​ c. The VGA card ​ d. The external monitor

a. The LCD inverter Correct Answer: The LCD inverter is likely not supplying voltage to the backlights (CCFLs) and will need to be replaced. Incorrect Answers: The external monitor was there to help us diagnose this malfunctioning laptop. And it did its job perfectly. While the LCD panel may seem like a good answer, it's probably not the BEST answer. We can still see the icons—they are just very dim and hard to make out. It's more likely a problem with the backlights or the inverters that power the backlights. The VGA card is working just fine, if it wasn't, we would have had nothing on the external monitor we connected.

A technician receives a report from a client that is having issues with colors on a monitor. The technician notices that the monitor does not appear to have any red hues. The technician sees that the monitor has two types of inputs. VGA is currently in use, and the HDMI cable is not.

Mike's newly configured computer (using manual IP settings) can't access a Web site by its fully-qualified domain name (FQDN), but he can access it by the Web site's IP address. Everyone else on the network can access the site by the FQDN. Which of the following is the MOST likely problem? ​ a. The computer's DNS settings are incorrect. ​ b. The computer's DNS Client service is disabled. ​ c. The computer does not have DNS permissions enabled on the default gateway. ​ d. The computer's DNS server is down.

a. The computer's DNS settings are incorrect. Correct Answer: Your DNS settings are incorrect. Given that most systems use DHCP, it's rare to have a problem like this, but if you typed in invalid manual DNS settings into your NIC's Properties, this can happen. Incorrect Answers: If you were to turn off the DNS Client service on your computer, you would get this problem. However, there is a much smaller chance that this service would be disabled than that someone had entered an invalid DNS service IP address. In a single network, everyone USUALLY uses the same DNS server, so if the DNS server is down for you, it's down for everyone else. Granted, you might have a different DNS server, so this answer is valid, but not as valid as entering an invalid DNS server IP address. Routers don't have an item in their Access Control Lists called "DNS permissions". You COULD block DNS from getting through your router by blocking port 53 (DNS), but then no one could get DNS access. Most routers have the ability to block a port number for a single IP or MAC address, but, again, it's simply too unlikely.

Which of the following statements is true regarding scanners? ​ a. The higher the resolution, the faster the image scans. ​ b. The brighter the image, the brighter the imaging lamp. ​ c. Scanners might need more internal memory to scan at higher resolutions. ​ d. The higher the scanner resolution, the larger the image file.

a. The higher the scanner resolution, the larger the image file. Increasing the resolution makes for more pixel data to store, and therefore larger image files.

You are installing a new video card on a PC. What is the most reliable place to get the most up-to-date driver? ​ a. The manufacturer's Web site ​ b. The installation disc that came with your new video card ​ c. The Windows driver library on the OS installation disc ​ d. The default PnP driver

a. The manufacturer's Web site Correct Answer: The best place to find the most up-to-date driver is the manufacturer's Web site. Incorrect Answers: Drivers may change after the card is made and shipped, so the installation disc is a no-go. Windows has a good library of drivers, but they will not be as up-to-date as the manufacturer's latest drivers. Any default driver is just a very basic driver designed for the lowest common denominator; such a driver will never be the most-up-to-date.

Martha's inkjet printer's output has the bottom of every letter missing in text and strange horizontal lines evenly spaced in her images. What part of the inkjet should she check for problems? ​ a. The printhead ​ b. The printer's resolution ​ c. The paper take-up rollers ​ d. The photosensitive drum

a. The printhead Correct Answer: Missing lines of horizontal print always point to a problem with the printhead. Incorrect Answers: The paper is being printed on, so it's not the take-up rollers. Inkjet printers do not have photosensitive drums. The printer resolution is not at fault, either.

The printer needs a maintenance kit replaced. ​ c. The TCP/IP print spooler service needs to be restarted. ​ d. Replace the network cable on the printer.

a. The security settings for the print spooler need to be modified to include the department. Correct Answer: Since other departments are accessing the print spooler without difficulty, the department that is having the problem does not have the proper permissions to use the print spooler. Incorrect Answers: The printer is working for other departments; no maintenance is needed. Other departments are accessing the print spooler without difficulty; the spooler is working properly. Other departments are accessing the printer properly; the cable does not need to be replaced.

What should you now suspect? ​ a. The network switch ​ b. The printer's IP address ​ c. The printer's NIC ​ d. The subnet mask for the entire network

b. The printer's IP address Correct Answer: The printer's IP address looks like it is not in the same network as the rest of the PCs—certainly worth checking next! Incorrect Answers: The network switch is not the problem if you can still access the server and the Internet. The printer's NIC is probably not the issue if it can self-test okay. The network's subnet mask is not the issue if the server and Internet can be accessed.

An older network needs to labeled to show where each network connection terminates in a patch panel. Which of the following tools would be BEST for the technician to identify the connections? ​ a. Cable tester ​ b. Tone generator and probe ​ c. Punchdown tool ​ d. RJ-45 loopback plug

b. Tone generator and probe When a cable is plugged into a tone generator, it sends a tone through the cable that can be detected through a receiver called a probe. The probe can be pointed at each cable on the switch. When the probe touches the cable that is plugged into the tone generator, the tone can be heard through the probe. Incorrect Answers: An RJ-45 loopback plug is used to test the connection, not to find a cable. A punch-down tool is used to insert the wire into a patch panel. A cable tester can only test a cable for electrical connection.

c. Error at boot: "Windows could not start" Error at boot: "Windows could not start." BOOT.INI's main job is to point to a valid copy of Windows, usually stored in a folder called \WINNT or \WINDOWS. If BOOT.INI doesn't point out a valid copy, this is the error you'll get. Incorrect Answer: Error at boot: "NTLDR is missing." Your Master Boot Record points to NTLDR. If there's a problem with the MBR, if it's corrupt or if the boot order is incorrect, then you'd get this error. Error at boot: "No boot device present". This happens when the BIOS is pointing to a drive that has no bootable partitions. Windows boots into Safe Mode only. While many issues may cause this to happen, if you're able to boot into Safe Mode, you have a bootable copy of Windows and your BOOT.INI is fine.

Any network using hubs can be substantially improved simply by replacing the hubs with: ​ a. Bridges ​ b. Routers ​ c. Switches ​ d. CAT6

c. Switches Correct Answer: Switches work at layer 2 of the OSI networking model—a standard in network communication that you will learn more about in Network+. By existing at layer 2, switches remember communication between nodes based on MAC addresses, creating direct connections instead of a single shared connection for the entire network in the case of hubs. Incorrect Answer: A bridge connects multiple network segments, but only has one incoming port and one outgoing port. A router is a different kind of networking device. Where switches connect computers together, routers connect networks together based on IP addresses rather than MAC addresses. CAT6 is Category 6 network cabling. This particular type of network cabling can go at speeds up to 10Gbps.

d. 127.0.0.1 Correct Answers: The IP address 127.0.0.1 is known as localhost. It enables the computer to ping itself. Incorrect Answers: 169.254.136.32 is an Automatic Private IP Addressing (APIPA) address and the other two answers are random valid IP addresses.

You set up all Windows 10 systems with TCP/IP and DHCP automatic addressing. One of the machines cannot connect to the network. You check its IP address with IPCONFIG and find that it has an address of 169.254.12.124. All the other machines in the network are working fine and you have confirmed that there are no cabling problems. How did this machine get this IP address, and what does it tell you? ​ a. This IP address indicates that someone manually assigned the address. ​ b. Windows remembers the last IP address assigned and is trying to use that address. ​ c. The IP is assigned by Automatic Private IP Addressing (APIPA) and this machine is not able to access the DHCP server. ​ d. Windows do not need an IP address to boot.

c. The IP is assigned by Automatic Private IP Addressing (APIPA) and this machine is not able to access the DHCP server. Automatic Private IP Addressing (APIPA) is generated by Windows and enables a computer to automatically assign an IP address if the Dynamic Host Configuration Protocol server is not present. If the DHCP server is unavailable, the computer assigns itself an IP address in the range of 169.254.0.0 - 169.254.255.255. Incorrect Answers: Windows remembers the last IP address assigned and is trying to use that address. This might be true if automatic addressing was disabled and you were using a static IP address. This IP address indicates that someone manually assigned the address. It could have been manually assigned, but because it is in the range of what APIPA assigns, it would be better to assume otherwise. Windows do not need an IP address to boot. Very true, but also an absurd answer to this question.

A technician is dispatched to a user's home to secure a wireless network. The SOHO user has only one system to connect wirelessly, yet wishes to protect her Wi-Fi network from unauthorized use. Which of the following will best meet the user's requirements? ​ a. Configure the use of static IP addresses ​ b. Configure the use of DHCP ​ c. Configure the network to utilize a proxy ​ d. Configure the router to allow access by specific MAC addresses

d. Configure the router to allow access by specific MAC addresses Correct Answer: MAC filtering enables you to select which computers you want to allow on to the network based on their MAC addresses. In this case, only one system needs to connect, so that's the one you should allow. Incorrect Answers: Using DHCP won't prevent unauthorized computers from connecting. DHCP just hands out IP addresses automatically. Static IP addresses won't help, either. Using a proxy just makes your computer connect to the Internet through an intermediary server.

A company is updating their office routers that handle all incoming and outgoing networking traffic. They would like the PCs to immediately connect to the internet and network resources, without any additional configuration. Which protocol should the technician use to meet the requirements? ​ a. Port forwarding ​ b. NAT ​ c. QoS ​ d. DHCP

d. DHCP Correct Answer: Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway. Incorrect Answers: NAT is used to translate private LAN addresses into a shared public address. Port forwarding allows calls to a particular port of a public address to be directed to a specified internal IP address and port. QoS is used in a router to prioritize and optimize inbound and outbound traffic.

A technician is installing and configuring a SOHO wireless network for a client. The client only wants five authorized computers to connect to the network within a defined IP range. Which of the following should the technician configure on the router? (Select two.) ​ a. SSID ​ b. DMZ ​ c. ARP ​ d. DHCP ​ e. MAC filtering

d. DHCP, e. MAC filtering Correct Answer: DHCP is the technology in charge of handing out IP addresses dynamically, and you can configure it to stay within a certain range of IP addresses. Meanwhile, MAC filtering enables you to create a list of PCs allowed on the network based on their MAC addresses. Incorrect Answers: A demilitarized zone (or DMZ) is a security measure designed to protect internal systems from outside threats by exposing a part of the network to the outside. ARP, or address resolution protocol, resolves network layer addresses (for example, IP addresses) to link-layer addresses (MAC addresses). SSID refers to the name of a wireless network.

While trying to type, a user reports that his notebook is randomly moving the cursor or mouse, which causes him to make a lot of typing errors. What action can the technician take to solve the issue for the user? ​ a. Adjust the settings so the mouse moves at a slower rate ​ b. Adjust the settings so the mouse moves at a faster rate ​ c. Reverse the buttons on the mouse pad ​ d. Disable the mouse touchpad.

d. Disable the mouse touchpad. Touchpads on laptops can get bumped by your thumb or the palm of your hands as you type. Most laptops have a button or a function key that will allow you to disable the mouse touchpad. Incorrect Answers: The rate of the mouse (quick or slow) is not effecting your cursor movement. This is generally caused by your hands touching the touch pad. Reversing the buttons will not assist, as it is commonly your hands touching the touch pad.

One of the network printers is producing copies where the toner is smeared on paper after printing. What component should be checked? ​ a. Paper output tray ​ b. Maintenance kit ​ c. Fuser ​ d. Print spooler

d. Fuser Thermal and laser printers use a fuser to heat the toner to a melting point. Once melted, the toner will fuse with the fibers of the paper. Incorrect Answers: A maintenance kit is a kit of replacement parts. It may assist in the repair, but it is not a component. The paper output tray is only used once the printing process is complete. It will not affect the print job. The print spooler is a software-based program that schedules print jobs; it does not affect the actual printing.

Scott's excited that his new laptop has a Gigabit Ethernet (1000BaseT) capable NIC. However, when he plugs it into his network at the office, he only gets 100Mbit speeds. What's the problem? ​ a. He needs to set the NIC's speed settings to "AUTO." ​ b. The other computers on the network only support 100BaseT. ​ c. He needs to update the NIC's drivers. ​ d. His switch only supports 100BaseT.

d. His switch only supports 100BaseT. Correct Answer: His switch only supports 100BaseT. When two Ethernet devices connect, they negotiate in order to set themselves to the highest possible speed. In this case, the switch is 100BaseT. Incorrect Answers: The drivers are fine. Your NIC's speed has nothing to do with the other computers. However, your actual data throughput will depend on the speed of the entire connection between the two communicating devices. Most NICs do have a property that defines the speed. In almost all cases this is set by default to "AUTO." There is a tiny chance that Scott's NIC is set to 100BaseT, but it's not nearly as common as the correct answer.

Which program is the best choice to use to clear the SSL cache? ​ a. Regedit ​ b. Windows Firewall ​ c. Windows Update ​ d. Internet Explorer

Kevin has just installed a LED-backlit LCD display. Which of the following is true about the native resolution of a digital display? ​ a. It is the lowest resolution ​ b. It causes the display to use pixel interpolation ​ c. It has the slowest refresh rate ​ d. It provides the best quality display

d. It provides the best quality display Correct Answer: When you set your display to use the native resolution, that means you are going to use the resolution that it was created for, which means it will provide you with the best quality image it can produce. Incorrect Answers: Granted, LCDs do have refresh rates. That's the time it takes to redraw the screen. However, LCDs don't have refresh rates the way a CRT has a refresh rate. Regardless, the refresh rate has nothing to do with the native resolution. Your LCD will experience pixel interpolation—an effect used to blur the edges of pixel to create rounded edges—if you DON'T set your monitor to the native resolution. The lowest resolution would be the exact opposite of the native resolution.

What would you use to enable multiple PCs to share a monitor? ​ a. Bridge ​ b. Wireless keyboard ​ c. Router ​ d. KVM

d. KVM Correct Answer: A KVM (which stands for keyboard, video, and mouse) enables you to share a single monitor and set of inputs among several computers. They're used extensively in computer repair shops. Incorrect Answers: A router connects two networks together. A network bridge combines two distinct networks into one larger network. A wireless keyboard won't help you use to share a monitor among PCs.

Incorrect Answers: RAID 1 is mirroring. RAID 5 is block-level striping with distributed parity. RAID 10 is a hybrid RAID. It's a mirrored set in a striped set.

You upgrade your network to 1000 Mbps from 100 Mbps. You install a new 1000-Mbps network adapter into your Windows system. You check the device manager and see no errors or warnings. You configure the TCP/IP settings to be as they were for the previous network adapter. Upon restarting the computer, you cannot access the network. You ping your IP address locally and receive the error message, "Request timed out." You then ping 127.0.0.1 and receive the same error message. What do you do? ​ a. Set the network adapter to run at 100 Mbps only. ​ b. Replace the network cabling. ​ c. Replace the network card drivers. ​ d. Replace the NIC.

d. Replace the NIC. You tried to ping 127.0.0.1, which is the loopback address, as well as your local IP address, and received the same error messages both times. This would indicate a faulty NIC in your workstation. Incorrect Answers: Nothing was changed about the cables, so that would not be the problem. Typically driver problems result in an error message during installation, so it's not the drivers. Also, you checked the device manager and everything was OK. Modern NICs can auto-negotiate for speed, so setting it to run at 100 Mbps wouldn't really do much.

You have just assembled your first PC. You hit the power button and the computer turns on. As the computer runs through POST, it starts beeping multiple times and you don't see anything displayed on the LCD. You notice there are no activity lights flashing for the HDD. However, when you check the inside of the computer, you can hear the drive spinning up. What is the NEXT thing you are going to check in order to get the PC functioning? ​ a. Replace the LCD with one that functions ​ b. Change the jumper settings to C/S ​ c. Reseat your Front Panel LEDs ​ d. Reseat your RAM

d. Reseat your RAM Correct Answer: Reseat your RAM. Amongst all the information you were able to gather from this scenario, knowing that it was making multiple beeps is an indication that the RAM is not seated correctly or worse yet... is bad! Incorrect Answers: Changing your hard drive settings to Cable Select (C/S) won't affect your outcome of POST. Replacing the LCD monitor won't change the lack of character on the screen because your RAM still needs to be seated. Reseating your Front Panel LED's, while a good idea considering you don't see hard drive activity, would not fix a no-boot situation like you are in.

A technician is called onsite to solve a network connection error. Upon arrival, the technician observes a message on the screen stating there is no boot drive found. Which of the following steps should the technician take next? ​ a. Repair the boot sector using recovery console ​ b. Inform the customer the hard drive has crashed and replaced the drive ​ c. Restart the system to verify the proper boot sequence ​ d. Restart the system, booting from a system recovery disc

d. Restart the system to verify the proper boot sequence Correct Answer: The first thing to do after a boot error is to make sure the boot sequence is correct. Incorrect Answers: You can use the recovery console to repair the boot sector on a drive, but if the drive isn't showing up at all, the recovery console won't help much. A system recovery disc won't help a boot device show up. Don't just replace the drive straight away. There may still be hope!

In such a scenario, the computer would still have turned on but would have been unable to access the OS.

In laser printer technology, what occurs during the writing stage of the image formation? ​ a. A uniform negative charge is applied to the drum. ​ b. An alternating charge is applied to the drum. ​ c. The print image is transferred to the paper. ​ d. The print image is written to the drum.

d. The print image is written to the drum. The laser strikes the drum in the areas that are to be printed, giving those areas a less negative charge. This makes these areas relatively positive so that they attract the toner.

Using your Web browser, you can access a number of Web sites. However, certain sites just give a screen saying, "You may not access this page." Which of the following is the most likely reason for this? ​ a. DNS is down on those sites. ​ b. You do not have HTTPS enabled. ​ c. The problem sites all require usernames and passwords ​ d. Your Web browser is using a proxy server

d. Your Web browser is using a proxy server Correct Answer: Your Web browser is using a proxy server. One of the main reasons for using a proxy server is to block unacceptable sites. The error described in the question is indicative of a proxy server. Incorrect Answers: If DNS was down, your browser would not be able to find the website and would give an error to that effect. While it is possible to shut down HTTPS on your browser, it is highly unlikely. If the problem sites all required usernames and passwords, you would get a prompt for a username and password.

A user complains of discoloration of the screen on their monitor after leaving their system on during vacation. This is an example of: ​ a. dead backlight ​ b. dead pixels ​ c. ESD ​ d. burn-in ​ e. EMI

d. burn-in Correct Answer: Burn-in on a monitor is a permanent discoloration of areas caused by the prolonged display of an image that does not move. It creates a permanent ghost-like image of the object. Screen savers were a common preventative solution to burn-in. Incorrect Answers: A dead backlight will not cause discoloration. ESD does not cause discoloration on the screen. Dead pixels will show small areas with no image display. EMI would only cause temporary display interference, it would not leave a discoloration.
