CompTIA Network+ (N10-007) — Question 427

A network administrator plans to install network connectivity at a new remote office location. The administrator is concerned about how to troubleshoot network connectivity issues and reconfigure the remote router. The technician should use __________.

Answer options

• A. an SD card with a backup configuration.
• B. a TFTP server on the main network for backup configurations.
• C. a modem using POTS.
• D. a second Ethernet interface for remote access.

Correct answer: C

Explanation

The correct answer is C, a modem using POTS, as it provides a reliable way to access the remote office for troubleshooting and configuration over traditional phone lines. Options A and B are not suitable for direct remote access to the router, while D involves an additional interface that does not address the need for remote connectivity.
