CompTIA Security+ (SY0-601) — Question 135

A Chief Security Officer is looking for a solution that can reduce the occurrence of customers receiving errors from back-end infrastructure when systems go offline unexpectedly. The security architect would like the solution to help maintain session persistence. Which of the following would BEST meet the requirements?

Answer options

• A. Reverse proxy
• B. NIC teaming
• C. Load balancer
• D. Forward proxy

Correct answer: C

Explanation

The correct answer is C, Load balancer, as it distributes incoming traffic across multiple servers, ensuring that if one server goes down, the others can take over, thus maintaining session persistence. Options A and D, Reverse proxy and Forward proxy, primarily handle requests and do not manage load distribution to maintain sessions. NIC teaming (Option B) enhances network reliability but does not directly address session persistence or error management for users.
