CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 811:

  Which of the following would be the MOST cost-effective recovery solution for a company's lower-priority applications?

  A. Warm site

  B. Cloud site

  C. Hot site

  D. Cold site

  Correct Answer: B

• Question 812:

  Which of the following describes the BEST device to configure as a DHCP relay?

  A. Bridge

  B. Router

  C. Layer 2 switch

  D. Hub

  Correct Answer: B

  A layer 3 switch would have received my vote but not a Data Link layer 2 switch. Routers, IP assignments (DHCP) occur at network layer.

• Question 813:

  A systems administrator wants to use the least amount of equipment to segment two departments that nave cables terminating in the same room. Which of the following would allow this to occur?

  A. A load balancer

  B. A proxy server

  C. A Layer 3 switch

  D. A hub

  E. A Layer 7 firewall

  F. The RSSI was not strong enough on the link

  Correct Answer: C

  A Layer 3 switch would allow this to occur, as it can segment the two departments by creating virtual LANs (VLANs) and routing traffic between them.

  A Layer 3 switch is a type of switch that can perform routing functions in addition to switching. It can use the network layer (Layer 3) of the OSI model to route traffic between different VLANs, which allows for the segmentation of different departments or networks within the same physical space. By creating VLANs for each department and using the Layer 3 switch to route traffic between them, the administrator can segment the two departments without the need for additional equipment.

• Question 814:

  Which of me following security controls indicates unauthorized hardware modifications?

  A. Biometric authentication

  B. Media device sanitization

  C. Change management policy

  D. Tamper-evident seals

  Correct Answer: D

• Question 815:

  A network administrator is troubleshooting a connectivity performance issue. As part of the troubleshooting process, the administrator performs a traceout from the client to the server, and also from the server to the client. While comparing the outputs, the administrator notes they show different hops between the hosts. Which of the following BEST explains these findings?

  A. Asymmetric routing

  B. A routing loop

  C. A switch loop

  D. An incorrect gateway

  Correct Answer: A

  Asymmetric routing is when the flow of packets in one direction passes through a different interface than that used for the return path

• Question 816:

  Logs show an unauthorized IP address entering a secure part of the network every night at 8:00 pm. The network administrator is concerned that this IP address will cause an issue to a critical server and would like to deny the IP address at the edge of the network. Which of the following solutions would address these concerns?

  A. Changing the VLAN of the web server

  B. Changing the server's IP address

  C. Implementing an ACL

  D. Instating a rule on the firewall connected to the web server

  Correct Answer: C

• Question 817:

  An ARP request is broadcasted and sends the following request.

  ''Who is 192.168.1.200? Tell 192.168.1.55''

  At which of the following layers of the OSI model does this request operate?

  A. Application

  B. Data link

  C. Transport

  D. Network

  E. Session

  Correct Answer: B

  An ARP request operates at the data link layer of the OSI model. ARP (Address Resolution Protocol) is a protocol that maps IP addresses to MAC addresses on a local area network. It allows devices to communicate with each other without knowing their MAC addresses beforehand. ARP operates at the data link layer (layer 2) of the OSI model, which is responsible for framing and addressing data packets on a physical medium.

• Question 818:

  A technician is consolidating a topology with multiple SSIDs into one unique SSID deployment. Which of the following features will be possible after this new configuration?

  A. Seamless roaming

  B. Basic service set

  C. WPA

  D. MU-MIMO

  Correct Answer: A

  After consolidating a topology with multiple SSIDs into one unique SSID deployment, seamless roaming will be possible. Seamless roaming is a feature that allows a device to move from one access point to another within the same network without losing its connection. This can be useful in a wireless network with multiple SSIDs, as it allows the device to roam freely between access points without having to disconnect and reconnect to the network. Other features such as basic service set (BSS), WPA, and MU-MIMO may still be possible after the new configuration, but they are not directly related to the consolidation of multiple SSIDs into a single SSID

• Question 819:

  Several end users viewing a training video report seeing pixelated images while watching. A network administrator reviews the core switch and is unable to find an immediate cause.

  Which of the following BEST explains what is occurring?

  A. Jitter

  B. Bandwidth

  C. Latency

  D. Giants

  Correct Answer: B

  Pixelated images while watching a video often indicate that the available bandwidth for transmitting the video stream is insufficient to maintain a high-quality, smooth playback. Bandwidth refers to the amount of data that can be transmitted over a network in a given time period. When there is not enough bandwidth available, the video stream may be compressed or downgraded, resulting in pixelation and reduced visual quality for the viewers. Jitter refers to the variation in the delay of received packets in a network. While jitter can impact the quality of real-time applications like video streaming, it typically causes issues such as audio or video synchronization problems rather than pixelation. Jitter could lead to audio and video being out of sync, but it's less likely to directly cause pixelated images in a video stream.

• Question 820:

  Which of the following DHCP settings would be used to ensure a device gets the same IP address each time it is connected to the network?

  A. Scope options

  B. Reservation

  C. Exclusion

  D. Relay

  E. Pool

  Correct Answer: A
