CompTIA Network+ (N10-008) — Question 855

A network administrator is trying to add network redundancy for the server farm. Which of the following can the network administrator configure to BEST provide this capability?

Answer options

• A. VRRP
• B. DNS
• C. UPS
• D. RPO

Correct answer: A

Explanation

The correct choice is VRRP, which stands for Virtual Router Redundancy Protocol, and it provides high availability by allowing multiple routers to work together, ensuring that if one fails, another can take over. DNS, UPS, and RPO do not offer the same level of network redundancy; DNS resolves names, UPS provides power backup, and RPO relates to data loss tolerance, but none directly enhance network redundancy like VRRP does.
