CompTIA Network+ (N10-007) — Question 287

An ISP technician frequently needs to administer a router remotely in the event of a configuration error or WAN outage. Which of the following technologies would facilitate the required connectivity?

Answer options

• A. Remote access VPN
• B. Remote file access
• C. Out-of-band
• D. Secure Shell

Correct answer: C

Explanation

The correct answer is C, Out-of-band, as it allows a technician to manage network devices independently of the main data network, which is crucial during outages. Remote access VPN (A) provides secure access but relies on the primary network being operational, while Remote file access (B) and Secure Shell (D) do not specifically address the need for remote router administration during outages.
