CompTIA Network+ (N10-007) — Question 112

A second router was installed on a network to be used as a backup for the primary router that works as a gateway. The infrastructure team does not want to change the IP address of the gateway on the devices. Which of the following network components should be used in this scenario?

Answer options

• A. Loopback IP
• B. Virtual IP
• C. Reserved IP
• D. Public IP

Correct answer: B

Explanation

The correct answer is B, Virtual IP, which allows multiple devices to share the same IP address, enabling seamless failover without changing device configurations. The other options do not provide the capability to maintain the same gateway IP address for devices in the event of a router failure.
