CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 561:

  A company is undergoing expansion but does not have sufficient rack space in its data center.

  Which of the following would be BEST to allow the company to host its new equipment without a major investment in facilities?

  A. Using a colocation service

  B. Using available rack space in branch offices

  C. Using a flat network topology

  D. Reorganizing the network rack and installing top-of-rack switching

  Correct Answer: A

  A colocation service is a service that provides rack space, power, cooling, security, and connectivity for a company's network equipment in a data center. A colocation service can be used when a company does not have sufficient rack space

  in its own data center and does not want to invest in building or expanding its own facilities. By using a colocation service, a company can host its new equipment in a professional and reliable environment without a major investment in

  facilities. References:

• Question 562:

  A network administrator would like to purchase a device that provides access ports to endpoints and has the ability to route between networks. Which of the following would be BEST for the administrator to purchase?

  A. An IPS

  B. A Layer 3 switch

  C. A router

  D. A wireless LAN controller

  Correct Answer: B

• Question 563:

  A consultant is working with two international companies. The companies will be sharing cloud resources for a project.

  Which of the following documents would provide an agreement on how to utilize the resources?

  A. MOU

  B. NDA

  C. AUP

  D. SLA

  Correct Answer: D

• Question 564:

  A company has wireless APS that were deployed with 802.11g. A network engineer has noticed more frequent reports of wireless performance issues during the lunch hour in comparison to the rest of the day. The engineer thinks bandwidth consumption will increase while users are on their breaks, but network utilization logs do not show increased bandwidth numbers. Which Of the following would MOST likely resolve this issue?

  A. Adding more wireless APS

  B. Increasing power settings to expand coverage

  C. Configuring the APS to be compatible with 802.1la

  D. Changing the wireless channel used

  Correct Answer: C

  802.11g is an older wireless standard that operates in the 2.4 GHz frequency band and has a maximum data rate of 54 Mbps. 802.11a is a newer wireless standard that operates in the 5 GHz frequency band and has a maximum data rate of 54 Mbps. By configuring the APS to be compatible with 802.11a, the network engineer can reduce interference and congestion in the 2.4 GHz band and improve wireless performance.

• Question 565:

  A technician is trying to determine whether an LACP bundle is fully operational. Which of the following commands will the technician MOST likely use?

  A. show interface

  B. show config

  C. how route

  D. show arp

  Correct Answer: A

  Link Aggregation Control Protocol (LACP) is a standard protocol used to bundle multiple physical links together to form a single logical link. To determine whether an LACP bundle is fully operational, the technician will likely use the "show interface" command. This command is used to display the status of network interfaces on a device, such as a switch or router.

  When the technician runs the "show interface" command, the output will include the status of the LACP bundle, such as whether it is up or down and whether all of the physical links in the bundle are active and working properly. The technician can also use the command "show interfaces ethernet [interface-number] lacp" to display the LACP information for a specific bundle.

• Question 566:

  A company streams video to multiple devices across a campus. When this happens, several users report a degradation of network performance. Which of the following would MOST likely address this issue?

  A. Enable IGMP snooping on the switches.

  B. Implement another DHCP server.

  C. Reconfigure port tagging for the video traffic.

  D. Change the SSID of the APs

  Correct Answer: A

  IGMP snooping stands for Internet Group Management Protocol snooping. It is a feature commonly found in network switches that helps optimize multicast traffic distribution. In this scenario, when video streaming is causing a degradation of network performance, enabling IGMP snooping on the switches would be the most likely solution.

  Multicast traffic, such as video streams, can flood the network if not properly managed. IGMP snooping allows switches to intelligently forward multicast traffic only to the ports where interested receivers are located. By enabling IGMP snooping, the switches can efficiently deliver the video streams to the devices requesting them, reducing unnecessary network congestion and improving overall network performance.

  Therefore, enabling IGMP snooping on the switches is the most appropriate solution to address the reported degradation of network performance during video streaming.

• Question 567:

  A network administrator is trying to add network redundancy for the server farm. Which of the following can the network administrator configure to BEST provide this capability?

  A. VRRP

  B. DNS

  C. UPS

  D. RPO

  Correct Answer: A

  VRRP is an open standard protocol, which is used to provide redundancy in a network. It is a network layer protocol (protocol number-112). The number of routers (group members) in a group acts as a virtual logical router which will be the default gateway of all the local hosts. If one router goes down, one of the other group members can take place for the responsibilities for forwarding the traffic.

• Question 568:

  A network technician receives a report from the server team that a server's network connection is not working correctly. The server team confirms the server is operating correctly except for the network connection. The technician checks the switchport connected to the server and reviews the following data;

  

  Which of the following should the network technician perform to correct the issue?

  A. Replace the Cat 5 patch cable with a Cat 6 cable

  B. Install a crossover cable between the server and the switch

  C. Reset the switchport configuration.

  D. Use NetFlow data from the switch to isolate the issue.

  E. Disable MDIX on the switchport and reboot the server.

  Correct Answer: A

  "Bad cables, incorrect pinouts, or bent pins: Faulty cables (with electrical characteristics preventing successful transmission) or faulty connectors (which do not properly make connections) can prevent successful data transmission at Layer 1.

  A bad cable could simply be an incorrect category of cable being used for a specific purpose. For example, using a Cat 5 cable (instead of a Cat 6 or higher cable) to connect two 1000BASE-TX devices would result in data corruption. Bent pins in a connector or incorrect pinouts could also cause data to become corrupted."

• Question 569:

  Which of the following is conducted frequently to maintain an updated list of a system's weaknesses?

  A. Penetration test

  B. Posture assessment

  C. Risk assessment

  D. Vulnerability scan

  Correct Answer: D

  A vulnerability scan is an automated process that checks a system or network for known vulnerabilities, such as outdated software versions, misconfigured settings, and unpatched systems. It checks the system against a database of known vulnerabilities and generates a report of any weaknesses that are found. This process is usually done periodically, such as weekly or monthly, to ensure that the system stays up-to-date with the latest patches and security updates.

• Question 570:

  A security engineer is installing a new IOS on the network. The engineer has asked a network administrator to ensure all traffic entering and leaving the router interface is available for the IDS. Which of the following should the network administrator do?

  A. Install a network tap for the IDS

  B. Configure ACLs to route traffic to the IDS.

  C. Install an additional NIC into the IDS

  D. Install a loopback adapter for the IDS.

  E. Add an additional route on the router for the IDS.

  Correct Answer: A

  a network tap is a way of connecting an IDS out of band, which means it does not interfere with the normal network traffic. A network tap allows you to view a copy of the network traffic transmitted over the media being tapped.
