CompTIA CompTIA Network+ N10-007 Questions & Answers

• Question 11:

  A lab environment hosts Internet-facing web servers and other experimental machines, which technicians use for various tasks. A technician installs software on one of the web servers to allow communication to the company's file server, but it is unable to connect to it. Other machines in the building are able to retrieve files from the file server. Which of the following is the MOST likely reason the web server cannot retrieve the files, and what should be done to resolve the problem?

  A. The lab environment's IDS is blocking the network traffic. The technician can whitelist the new application in the IDS.

  B. The lab environment is located in the DMZ, and traffic to the LAN zone is denied by default. The technician can move the computer to another zone or request an exception from the administrator.

  C. The lab environment has lost connectivity to the company router, and the switch needs to be rebooted. The technician can get the key to the wiring closet and manually restart the switch.

  D. The lab environment is currently set up with hubs instead of switches, and the requests are getting bounced back. The technician can submit a request for upgraded equipment to management.

  Correct Answer: B

• Question 12:

  A company recently completed construction of a new remote office. The network administrator needs to set up new network devices, such as printers and a local file server, at the remote location. The new devices need to be configured on the same Layer 2 network as the main office. Which of the following should the network administrator configure?

  A. Remote desktop gateway

  B. Transport mode IPSec

  C. SSH tunneling

  D. TLS VPN

  Correct Answer: D

• Question 13:

  A technician is performing a site survey in an area of a university where both faculty and students are reporting poor performance of their wireless connections. The technician gathers the following data in the problem area: Which of the following would MOST likely resolve the issue?

  

  A. There are too many wireless clients. Increase the number of APs to handle the traffic load.

  B. The SNR is not at an acceptable level. Change the channel on the APs.

  C. The signal strength is too low. Replace the equipment with devices that have better radio antennas.

  D. The channel numbers on some APs are invalid. Switch AP2 and AP3 to use channel 1.

  E. The type of antenna is inappropriate for the environment. Switch to 13dBi Yagi antennas.

  Correct Answer: B

• Question 14:

• Question 15:

  SIMULATION

  After recent changes to the pictured network, several users are unable to access the servers. Only PC1, PC2, PC3, and PC4 are clickable and will give you access to the command prompt and the adapter configuration tabs.

  INSTRUCTIONS

  Verify the settings by using the command prompt, after making any system changes.

  Next, restore connectivity by making the appropriate changes to the infrastructure.

• Question 16:

  SIMULATION

  You have been tasked with setting up a wireless network in an office. The network will consist of 3 Access Points and a single switch. The network must meet the following parameters:

  The SSIDs need to be configured as CorpNet with a key of S3cr3t!

  The wireless signals should not interfere with each other.

  The subnet the Access Points and switch are on should only support 30 devices maximum.

  The Access Points should be configured to only support TKIP clients at a maximum speed.

  INSTRUCTIONS

  Click on the devices to review their information and adjust the settings of the APs to meet the given requirements.

  B. An IDS will detect traffic anomalies, alert and log them, and block the traffic.

  C. An IDS will detect previously unknown traffic anomalies, alert and log them, and block the traffic.

  D. An IPS will detect traffic anomalies, alert and log them, and allow them through the network.

  E. An IPS will detect previously unknown traffic signatures, and alert and log them.

  F. An IPS will detect traffic anomalies and a predefined signature pattern, alert and log them, and block the traffic.

  Correct Answer: AF

• Question 19:
