CompTIA CompTIA Mobility+ N10-005 Questions & Answers

• Question 601:

  A network technician has just upgraded a switch. The new switch's IP range and subnet mask correctly match other network devices. The technician cannot ping any device outside of the switch's own IP subnet. The previous switch worked correctly with the same settings.

  Which of the following is MOST likely the problem?

  A. The proxy server is set incorrectly.

  B. The Ethernet cable is pinched.

  C. The network gateway is set incorrectly.

  D. The IP address is set incorrectly.

  Correct Answer: C

  When user is able to ping everything in its own subnet that means that all the hosts are reachable however when you are not able to ping anything outside of this subnet then please check if the device is sending traffic to the correct host who should forward it to the further devices.

• Question 602:

  Which of the following standards can operate at either 20MHz or 40MHz channel spacing?

  A. 802.11a

  B. 802.11b

  C. 802.11g

  D. 802.11n

  Correct Answer: D

  The 2.4 GHz ISM band is fairly congested. With 802.11n, there is the option to double the bandwidth per channel to 40 MHz which results in slightly more than double the data rate. However, when in 2.4 GHz, enabling this option takes up to 82%[10] of the unlicensed band, which in many areas may prove to be infeasible.

  The specification calls for requiring one primary 20 MHz channel as well as a secondary adjacent channel spaced ?0 MHz away. The primary channel is used for communications with clients incapable of 40 MHz mode. When in 40 MHz mode, the center frequency is actually the mean of the primary and secondary channels.

  Which of the following should the technician do NEXT?

  A. Plan to reboot the concentrator as the potential solution

  B. Escalate the problem to management

  C. Continue to speak to users, questioning if changes have been made

  D. Test access to the concentrator to confirm the status

  Correct Answer: D

• Question 606:

  A technician has narrowed down the cause of a problem to two possible sources. Which of the following should the technician do NEXT?

  A. Implement a solution for both causes to be sure all possibilities are covered.

  B. Choose the more likely cause and test to confirm.

  C. Establish a plan of action for each.

  D. Choose the less likely cause and test to eliminate.

  Correct Answer: B

• Question 607:

  A user reports that they are unable to connect to the network. Upon further investigation, a technician notices that the user has an IP address/subnet mask combination of 192.168.204.255/24. The default gateway for the network is

  192.168.204.254.

  Which of the following could the user's IP address be changed to so that they could connect to the network?

  A. 192.168.204.0/27

  B. 192.168.204.1/27

  C. 192.168.204.112/24

  D. 192.168.204.254/24

  Correct Answer: C
