Which of the following actions should the administrator take to decrease the CPU utilization?

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.)
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.

Answer: B,C

Explanation:

Moving the digital certificate to the load balancer and configuring the communication between the load balancer and the VMs to use HTTP are two actions that will decrease the CPU utilization of the VMs that are running behind a network load balancer with two VMs, each with its own digital certificate configured. Moving the digital certificate to the load balancer will offload the SSL/TLS encryption and decryption tasks from the VMs to the load balancer, which can reduce the CPU overhead and improve performance. Configuring the communication between the load balancer and the VMs to use HTTP will eliminate the need for encryption and decryption between them, which can also reduce CPU consumption. However, this may introduce security risks if sensitive data is transmitted over HTTP.
