CompTIA Cloud+ (CV0-003) — Question 11

A systems administrator is analyzing a report of slow performance in a cloud application. This application is working behind a network load balancer with two VMs, and each VM has its own digital certificate configured. Currently, each VM is consuming 85% CPU on average. Due to cost restrictions, the administrator cannot scale vertically or horizontally in the environment. Which of the following actions should the administrator take to decrease the CPU utilization? (Choose two.)

Answer options

• A. Configure the communication between the load balancer and the VMs to use a VPN.
• B. Move the digital certificate to the load balancer.
• C. Configure the communication between the load balancer and the VMs to use HTTP.
• D. Reissue digital certificates on the VMs.
• E. Configure the communication between the load balancer and the VMs to use HTTPS.
• F. Keep the digital certificates on the VMs.

Correct answer: B, C

Explanation

Moving the digital certificate to the load balancer (option B) reduces the processing load on the VMs since they will not need to handle SSL termination. Switching the communication to HTTP (option C) can also lower CPU utilization by eliminating the overhead of HTTPS encryption, allowing the VMs to focus on application processing. The other options either maintain or increase the CPU load, which contradicts the goal of reducing utilization.
