CompTIA CySA+ (CS0-001) — Question 26

A company has recently launched a new billing invoice website for a few key vendors. The cybersecurity analyst is receiving calls that the website is performing slowly and the pages sometimes time out. The analyst notices the website is receiving millions of requests, causing the service to become unavailable. Which of the following can be implemented to maintain the availability of the website?

Answer options

• A. VPN
• B. Honeypot
• C. Whitelisting
• D. DMZ
• E. MAC filtering

Correct answer: C

Explanation

The correct answer is C - Whitelisting, as it can help control access to the website by allowing only authorized users, thereby reducing the number of requests and enhancing availability. The other options like VPN, Honeypot, DMZ, and MAC filtering do not directly address the issue of excessive requests affecting service availability.
