CompTIA Network+ (N10-008) — Question 420

A network administrator is configuring a static DSL connection on the perimeter router to use a backup route to the fiber connection using OSPF routing. The administrator notices all traffic is going over the DSL connection and both links are working. Which of the following should the administrator do to adjust the routing settings for the fiber connection to be used by the router?

Answer options

• A. Add the DSL connection to the neighbor table for OSPF protocol
• B. Change the routing protocol to EIGRP for the fiber connection
• C. Increase the administrative distance of the DSL connection
• D. Create a separate VLAN for the DSL connection

Correct answer: C

Explanation

Increasing the administrative distance of the DSL connection makes it less preferred compared to the fiber connection, allowing the router to prioritize the fiber link for traffic. The other options do not address the issue effectively; adding the DSL connection to the neighbor table does not change routing preference, switching protocols could complicate the setup unnecessarily, and creating a separate VLAN does not impact OSPF routing metrics.
