CompTIA CompTIA Mobility+ N10-005 Questions & Answers

• Question 161:

  Several users are reporting connectivity issues with their laptops. Upon further investigation, the network technician identifies that their laptops have been attacked from a specific IP address outside of the network. Which of the following would need to be configured to prevent any further attacks from that IP address?

  A. Port security

  B. IDS

  C. Firewall rules

  D. Switch VLAN assignments

  Correct Answer: C

  Firewall rules block or allow specific traffic passing through from one side of the router to the other. Inbound rules (WAN to LAN) restrict access by outsiders to private resources, selectively allowing only specific outside users to access specific resources. Outbound rules (LAN to WAN) determine what outside resources local users can have access to.

• Question 162:

  Which of the following performs authentication and provides a secure connection by using 3DES to encrypt all information between two systems?

  A. HTTPS

  B. SSH

  C. RSA

  D. SSL

  Correct Answer: B

  DES encryption algorithm encrypts data three times. Three 64-bit keys are used, instead of one, for an overall key length of 192 bits (the first encryption is encrypted with second key, and the resulting cipher text is again encrypted with a third key).

• Question 163:

  Which of the following is used to limit the amount of bandwidth used on a link for different applications to improve overall performance?

  A. QoS

  B. Fault tolerance

  C. Load balancing

  D. Traffic shaping

  Correct Answer: D

• Question 164:

  The security administrator needs to restrict specific devices from connecting to certain WAPs. Which of the following security measures would BEST fulfill this need?

  A. WAP placement

  B. MAC address filtering

  C. Content filtering

  D. Encryption type and strength

  Correct Answer: B

  MAC Filtering (or EUI filtering, or layer 2 address filtering) is a security access control method whereby the 48-bit address assigned to each network card is used to determine access to the network.

• Question 165:
