CompTIA Network+ (N10-007) — Question 160

Joe, a technician, is attempting to resolve an issue with an off-site router remotely. Joe needs to reset the WAN connection settings and wants to ensure he will have access to the router at all times to monitor the changes.
Which of the following solutions would BEST meet this goal?

Answer options

• A. Use a secure SSH connection over the WAN link.
• B. Telnet into the router over the company VPN.
• C. Implement a modem on the AUX port.
• D. Configure a DSL router to the console port.

Correct answer: C

Explanation

The best solution is to set up a modem on the AUX port, as this allows for out-of-band management and ensures access to the router regardless of the WAN link's status. Using SSH or Telnet relies on the WAN connection being functional, which may not be the case if the issue is with the WAN settings. Configuring a DSL router to the console port does not provide the desired remote access capabilities.
