If you are using the Zigbee protocol, which of the following types of network is being used? A. Mesh B. Bus C. Ring D. Star

A. Mesh Notes: A mesh network topology is one in which the intermediary network devices are connected directly, but not hierarchically to as many other nodes as possible. They cooperate in such a way so that they can route traffic in the most efficient manner. A full mesh network is one where each network node is connected to all other nodes in the network. This is the most reliable and redundant network topology as it provides the most alternative routes from any source to any destination. Zigbee is not implemented in star, Bus, or Ring topology. A ring topology is a bus topology in a closed loop where data travels around the ring in one direction. When one node sends data to another, the data passes through each intermediate node on the ring until it reaches its destination. A bus network topology is one where each node is connected to a single cable using specialized interface connectors. This central cable is the mainstay of the network and is known as the bus. A signal from the source travels in both directions to all apparatuses connected on the bus cable until it finds the intended recipient. In a network star topology, each network host is connected to a central network device with a point-to-point connection. So, it can be said that every host is indirectly connected to every other host with the help of the central network device.

You need to provide resources for a server that you have set up with a cloud service provider. You do not want the cloud service provider's intervention or dependency on them as you may need to add more resources at odd office hours. Which of the following methods would be good to use in this scenario? [Choose two.] A. Resource pooling B. Rapid elasticity C. Measured service D. On-demand

B. Rapid elasticity D. On-demand Notes: With on-demand, you can provision the resources, such as storage, as and when you need it without the intervention of the cloud service provider. The Rapid elasticity feature gives the advantage of pay-as-you-grow. You can scale up or scale down the infrastructure as you may need. With Rapid elasticity, you can get resources on an instant basis without having to request them from the cloud service provider. The cloud service provider charges the client for services and resource usage. In resource pooling, the cloud service provider provides all resources in a resource pool. You can opt for a specific resource, such as network bandwidth or storage.

You have a USB 2.0 port on your laptop. You usually use this port to connect a USB drive. However, now the USB port is not detecting the USB drive, which is working on another system.

Verify the full system functionality B. Test your solution C. Establish a plan to resolve the problem D. Assume that the problem is resolved

B. Test your solution Notes: When you have a fair idea about the issue, you have developed a theory. Your theory is confirmed after you have reproduced the issue. Then, you need to establish a plan to resolve the issue. You are in the third stage of troubleshooting methodology. You can test the theory in which you also verify the hardware and software configuration. In the fourth stage, after the problem is resolved, you verify the system functionality. You cannot assume that the problem is solved.

You are using Internet Explorer to access an FTP server on the Internet. When you attempt to connect, you get the following error: Windows cannot access this folder. Make sure you typed the file name correctly and that you have consent to access to the folder. The operation timed out. What could be the probable cause? [Choose all that apply.] A. The FTP Server is not configured to accept connections from Internet Explorer. B. The Enable folder view for FTP sites option is enabled in Internet Explorer. C. A firewall on the network is preventing access. D. It is a network bandwidth issue.

B. The Enable folder view for FTP sites option is enabled in Internet Explorer. C. A firewall on the network is preventing access. Notes: This error can be caused due to the following reasons: A firewall is preventing the access to the FTP server and therefore, the connection times out as the connection is not built within the defined time. The second reason is that the Enable folder view for FTP sites option is enabled in Internet Explorer. With this option enabled, Internet Explorer attempts to bypass the firewall and connect to the FTP server directly, which it cannot. You do not need to configure the FTP server to accept connections from Internet Explorer. Network bandwidth issues do not cause this issue.

Which of the following statement can be considered a drawback for the BD-RE discs when you need to re-write them? A. They are slow B. They perform a pre-write C. They can be written once only D. They can write only audio files

B. They perform a pre-write Notes: The only drawback when rewriting BD-RE is that there is a pre-write time. It takes time to erase the existing data and then write the new data. The BD-RE discs are not slow and can be written multiple times. They can store different formats of data.

You use an old laptop that does not have a wireless adapter. You need to connect this laptop to a wireless network. Which of the following methods could you use? A. Add a PCI wireless card in the laptop B. Use a USB wireless adapter C. Connect the wireless access point to the laptop D. Use a Bluetooth dongle

B. Use a USB wireless adapter Notes: You can use a USB wireless adapter and connect to a wireless network. This is the only possible method. You can connect the wireless access point to the laptop using an Ethernet cable, but it is similar to connecting to a wired network. A laptop will not have enough space to add a PCI wireless card, and therefore, this option can be ruled out. A Bluetooth dongle will provide Bluetooth connectivity but not wireless.

Your office has satellite Internet connectivity, which is causing problems. Every time, there is a thunderstorm or heavy rains, there is intermediate connectivity. You want to replace this connection with a fast connection that has low latency and has high speed. What should you do? A. Use a Satellite connection B. Use a fiber connection C. Use a cable connection D. Use a mobile hotspot connection

B. Use a fiber connection Notes: It would be better to replace the satellite connection with a fiber connection. Out of the given choices, only Fiber meets the requirements stated in the scenario. Cable and DSL connections can experience high latency and are not as fast as compared to the Fiber connection, which can provide speed up to 1 Gbps. A hotspot connection is good for an individual, but it cannot serve the entire office and also does not provide high speed.

You are deploying a Web application that will have a database running in the backend. Users from the Internet will log in to the application. You need to secure the application and ensure that the data between each user's system and the Web application is encrypted during transmission. What should you do? Answers A. Enable Windows Firewall on each user's system B. Deploy a Web Application Firewall on the same server as the Web application C. Use the HTTPS with the Web application D. Deploy a network firewall that allows only the Web application

C. Use the HTTPS with the Web application Notes: You need to use HTTPS with the Web application. When HTTPS is used, it encrypts the traffic between the user's system and the Web application. In this scenario, it is the most suitable solution. A Web Application Firewall (WAF) is used for protecting the Web application from attacks, such as cross-site scripting (XSS). It cannot protect the traffic between the user's system and the Web application. Similarly, enabling Windows Firewall will protect each user's system but not the traffic going to the Web application. A network firewall protects the network traffic and the systems that are part of the network. If the Web application is hosted on your network, you will need to allow port 443 for the users to connect to the Web application.

You have been using a Gmail account on your mobile. However, you are no longer able to send E-mails and receive emails. You open Google Chrome and search online for solutions but do not get a proper solution. Which of the following methods can help you resolve this situation? A. Turn off the Airplane mode B. Check if you are connected to the Internet C. Check your password D. Enable the mobile data on the mobile

C. Check your password Note: You can search on google so the other options are eliminated.

You are the administrator for a small network of 20 computers that contain static IP configurations. You need to add 100 more computers on this network. Which of the following protocols would you use to avoid having to configure the IP network configuration parameters of each computer individually? A. NAT B. WINS C. DHCP D. DNS

C. DHCP Notes: Dynamic Host Configuration Protocol (DHCP) automatically provides IP network configuration parameters such as IP addressing, subnet mask, gateway, and DNS server information to devices on the network. The Domain Name System (DNS) is a hierarchical decentralized naming system for computer services and other resources connected to the Internet. It is used to associate various information with domain names. More specifically, it is used to translate IP addresses to human-friendly domain names. Network Address Translation (NAT) is a method of translating one IP address space into another by modifying the network information in the header of the IP packets. Windows Internet Name Service (WINS) is used for NetBIOS name resolution.

You have installed a RAID controller in a system in a proper way. However, the system is not able to detect it. What should be your first step to resolve this issue? A. Install the RAID controller's drivers B. Reseat the RAID controller C. Enable the RAID controller in the BIOS D. Ensure all drive cables are connected properly

C. Enable the RAID controller in the BIOS Notes: After installing the RAID controller, if it is not detected, then you should enable it in the BIOS. After that, reboot the system and RAID controller will be recognized. You do not need to install the RAID controller drivers as the first step. If the operating system detects the RAID controller but does not recognize it, then the drivers need to be installed. Since the scenario states that the RAID controller is installed in a proper way, reseating it is not required. If one or more hard drives are not detected, then you need to ensure all cables are connected properly.

Which of the following can take full advantage of the mATX motherboard? A. Web development B. Document creation C. Gaming D. Web hosting

You are configuring a messaging client on your laptop. You want to retain the messages on the server but also want them to synchronize them with the messaging client on your laptop. Any changes made to the messages must get replicated with the server. Which of the following protocol should you configure in the messaging client? A. POP3 B. S/MIME C. IMAP D. SMTP

C. IMAP The Internet Message Access Protocol (IMAP) stores messages on the server and allows the user to work on the server directly. You will be able to retain the messages on the server as well as synchronize them with the messaging client on your laptop. Any changes made to the messages will get replicated with the server. The Secure/Multipurpose Internet Mail Extensions or S/MIME is used to encrypt and digitally sign the E-mails. The Simple Mail Transfer Protocol (SMTP) is used for sending E-mails across the Internet. POP3 is a client/server protocol that downloads the E-mails from a messaging server. After the E-mails are downloaded, they are deleted from the messaging server.

When you enable Bluetooth on a mobile handset, how does it find a device for pairing? A. It will attempt to connect Bluetooth devices within 10-meters radius B. The connection will be automatically enabled with all Bluetooth-enabled devices C. It will scan for and list Bluetooth-enabled devices within 10-meters radius D. It will attempt to create a connection with all Bluetooth -enabled devices

C. It will scan for and list Bluetooth-enabled devices within 10-meters radius Notes: Show explanation Show answer When you enable Bluetooth on a mobile handset, it will find Bluetooth-enabled devices within 10-meters radius. However, no automatic connection is established. When a user selects a device, then the receiving device sends a unique key that is displayed on the mobile handset. None of the remaining options are correct and are not performed when Bluetooth is enabled on a mobile handset.

You are using a dual-slot graphics adapter in a gaming system, which overheats within a few hours of usage. Which of the cooling method would be most appropriate? A. Temperature sensors B. Thermal paste C. Liquid-based cooling D. Heat pipes

C. Liquid-based cooling Notes: The dual-slot graphics adapter is placed in two adjacent slots on the motherboard and blocks the air flow. Therefore, the system tends to overheat. The liquid-based cooling uses small hoses to send the cooling liquid through the heat exchanger, which that absorbs heat. Thermal paste sits between the heat sink and the processor. It draws the heat from the processor and passes it on to the heat sink. Temperature sensors are built-in to the processors. They help the processor to acknowledge overheating. Once the processor acknowledges that, then it shuts itself down until it is cooled down. Heat pipes vaporize coolant liquid when a component generates heat.

Your laptop's lithium-ion battery provides less than one-hour battery time. What should you do to fix this issue? A. Clean the battery and battery contacts on the laptop B. Drain the battery completely and then charge it C. Replace the battery with a new one D. Take out the battery and reseat it properly

C. Replace the battery with a new one Notes: When the battery provides less than one hour of charging, you can be sure that the battery is reaching the end of its lifecycle. The battery time will keep reducing further until, eventually, the battery fails to provide any battery time at all. It is advisable to replace the battery before the battery reaches that stage. If suddenly you find that the laptop is not able to run on the battery, then you should clean the battery and battery contacts on the laptop. You can also take out the battery and then reseat it completely. If the battery is not seated properly, or if the battery contacts are dirty, the battery may not be able to charge or may not be able to provide the backup. Drain the battery and then charging it will not help in this case. Ideally, you should be draining the battery as much as possible and then charging it.

You do not have a spare cable to charge your phone, and you suspect that the charging port on the phone has got dust inside. You need to clean this port. What should you do? [Choose all that apply.] A. Blow into the charging port B. Use a needle to scrape the dust C. Shake the phone D. Use compressed air E. Use a pin to draw out the dust carefully

C. Shake the phone D. Use compressed air Notes: The best method for removing dust and debris from the changing port on a mobile phone is to use a couple of short quick bursts of compressed air. You may also want to try shaking the phone as gently as possible to see if any loose dust or debris has been dislodged. You would not want to physically blow into the port as air from your mouth may contain moisture, which can cause issues with sensitive electronic components. You should also not stick metal objects such as pins and paperclips into the port as they may hold a static charge that could potentially damage the phone.

If you are building a media streaming server, which of the following should be the most critical requirement of the system? A. High-end cooling B. CPU C. Storage D. Memory

Check on the Internet connectivity B. De-register and register Kindle on your laptop C. Clear the temporary files on your laptop D. Remove the book from the mobile and add it on both the devices

D. Remove the book from the mobile and add it on both the devices Notes: Since the progress of the book is not getting replicated, you should remove the book from both the devices and then add it again. It would start the synchronizing process. This could happen when there is an update for the book. It could break the progress synchronization. You need not de-register and register kindle on your laptop. It would break the synchronization for the remaining books. Since you can synchronize the remaining books, Internet connectivity is not an issue. Temporary files cleanup does not help as these files are saved in the user's profile in the Windows system.

You are using a computer with an IP address of 192.168.2.44 and a subnet mask of 255.255.255.0. You can ping the destination of 192.168.2.66 but not 192.168.3.21 even though you know that the latter is a functioning workstation. The workstation with the IP address, 192.168.3.21 can ping systems on the 192.168.2.x subnet. What could be the reason for this? A. The firewall between both the subnets is blocking the traffic. B. Both are located on a different subnet. C. Duplicate MAC addresses have been detected. D. The default gateway is configured incorrectly.

D. The default gateway is configured incorrectly. Notes: When connectivity is available between hosts on the same subnet and yet is not available between hosts in different subnets, the most likely culprit is the default gateway settings. This is because the default gateway is used for connectivity to networks outside of the local one. A device will examine the destination IP address, and if it is not in the same subnet as itself, it will send the packets to the default gateway. The default gateway will then route the packet appropriately to get to its destination. If the default gateway is configured incorrectly, communication of a host with subnets outside of its own is not possible.

Your organization uses Active Directory with Exchange Server 2016 for messaging. The network is protected by a firewall. You need your laptop to be configured with Outlook 2016 using the IMAP protocol. When you attempt to login to the E-mail account using your domain account, the authentication fails. However, you are able to log in to your laptop. You check with IT support and no other remote user has reported this issue. What could be the probable cause? A. Port 143 is blocked on the firewall B. Exchange Server does not support IMAP. C. IMAP is incompatible with Outlook 2016. D. The password contains Unicode characters. E. The Outlook profile is corrupt.

D. The password contains Unicode characters. Notes: There is an issue with the IMAP and Outlook 2016 and IMAP fails to authenticate a user if the password contains Unicode characters. As a workaround, you can change your password, use a different protocol, such as POP3, or downgrade the Outlook 2016 to 2013. The same password will then work. Port 143 is already open on the firewall as no other remote user has an issue in using IMAP, which is fully compatible with IMAP. Exchange server supports IMAP and POP3. You are currently setting up the Outlook profile and authentication is in process. Once authentication completes, then the profile will be set up.

You have configured two devices to share contact information over NFC. The information sharing starts, but then you move one of the devices a little further away accidentally. Contact sharing between devices now fails. What could be the probable cause? A. NFC connectivity is time-bound, and time has lapsed. B. Both devices are incompatible with each other. C. It is not possible to share contacts using NFC. D. There should be a maximum of two-inches distance between both the devices.

D. There should be a maximum of two-inches distance between both the devices. Notes: The only possible cause, in this case, is that both the devices are more than two inches apart from each other. The maximum distance between the two devices should be two inches when using NFC. You can share contacts using NFC. Since both the devices were earlier connecting, they cannot be incompatible. NFC connectivity is not time bound.

If you want to access blocked websites, hide your location, encrypt data, which of the following should you do? A. Use remote access B. Use Encryption C. Use firewall D. Use VPN

D. Use VPN Notes: VPNs can help access blocked websites, hide your location, encrypt your data, and much more. VPN essentially creates a virtual tunnel between a computer and a server. That virtual cable creates a tunnel that encrypts any data that passes through it. Encryption is used for protecting data when you do not want anyone but the legitimate user to access it. A firewall protects a system, server, or network by allowing or denying access. Remote access allows a user to connect to a remote system.

You have recently setup a new virtual environment with multiple virtual machines. You need to protect these virtual machines and need to ensure that the entire environment is secured. Which device should you use? A. VM B. Router C. Next Generation Firewall D. Virtual firewall E. Virtual switch

D. Virtual firewall Notes: A virtual firewall is a network security device that provides security features of a traditional firewall but functions entirely within a virtualized environment.

In which of the following situations would you update the radio firmware? A. When a device is non-functional B. When there is an issue with the processing speed C. When there is an issue with device memory D. When there is an issue with the cellular signals

D. When there is an issue with the cellular signals Notes: You should update the radio firmware when there is an issue with the cellular connection. A radio firmware contains the configuration parameters for the cellular settings. None of the remaining issues can be fixed with the radio firmware.

You need to transfer critical files from your desktop to a file server. You want to ensure that you use a private and safe data stream. Which of the following should you use? A. SSL B. FTP C. SSH D. SMTP

SSH Notes: Secure Shell or SSH is used to create a secure channel over which Secure File Transfer Protocol (SFTP) functions. SSH ensures that the server has already authenticated the client and that the identity of the client user is available to the protocol.

You have installed an '802.11a' wireless network router which is rated at 54 Mbps but, you observe that it is not able to transmit data even at a rate of 30 Mbps. Where may the problem lie? A. The wireless driver needs to be updated as it will increase the data throughput and solve the issue B. There may be an issue of network congestion so switching the router off and on again will resolve the issue C. The maximum theoretical transmitted throughput is 1/2 of the maximum bi-directional throughput of 27 Mbps. D. The router you have purchased is expected to handle the throughput of 30 Mbps as per written specifications, but the device seems to be of substandard in quality.

The maximum theoretical transmitted throughput is 1/2 of the maximum bi-directional throughput of 27 Mbps. Explanation: Wireless devices are not full duplex. Wireless data has unidirectional flow at any one point in time due to which in actual operation the maximum data transfer rate or throughput will be well below half of the raw wireless network speed. Other options are incorrect because restarting, updating drivers, or going for the best quality product cannot exceed the maximum theoretical limit of 27 Mbps.

You have to deploy a solution on a client site where the solution must consist of a Firewall, Anti-spam, Content filtering, DLP, and Malware scanner. The client wants to receive alerts if suspicious traffic is detected. It should also be able to provide reports on the number of viruses and spam messages blocked, and summaries of content filter violations. The client does not want to load the network with multiple devices and wants a single solution. To be able to meet your goal, which of the following would be an optimal solution for the client? A. Antimalware Tool B. Content Filtering Tool C. Data Loss Prevention (DLP) D. Firewall E. Unified Threat Management (UTM)

Unified Threat Management (UTM) Notes: UTM can perform the functions of: Firewall Anti-spam Content filtering DLP Malware scanner

You configure a Wireless Access Point (WAP); you disable the SSID broadcast. What will be the outcome of this configuration? A. Users will see the wireless network and it will be connected automatically. B. Users will no longer be able to either see the wireless network or connect to itUsers will not be able to connect to the wireless network. C. Users will see the wireless network, but they will not be able to connect to it.. D. Users will no longer be able to see the wireless network, but they can connect to it manually

Users will no longer be able to see the wireless network, but they can connect to it manually Notes: SSID broadcast is the internet name showing up as the connection.
