CompTIA Cloud+ (CV0-003) — Question 148

A systems administrator is troubleshooting an application that is configured to auto-scale with a minimum of two nodes and a maximum of four. The application will scale out if the CPU utilization of one of the nodes exceeds 80% for more than five minutes and will scale in if the CPU utilization of one of the nodes drops under
20% for more than ten minutes. There is a reverse proxy in front of the application. The systems administrator notices two of the nodes are often running over 80% for a long period of time, which is triggering the creation of the other two nodes; however, they are being created and terminated while the load in the first two remains over 50% all the time. Which of the following should the administrator configure to fix this issue?

Answer options

• A. Disable DNS caching in the reverse proxy.
• B. Reduce the minimum node count to one.
• C. Disable TLS tickets.
• D. Reduce the scale-out rule to 50%.
• E. Increase the scale-in rule to 50%.

Correct answer: E

Explanation

The correct answer is E because increasing the scale-in rule to 50% will prevent nodes from being removed while the remaining nodes are still under significant load, ensuring there are enough resources to handle traffic. The other options do not address the issue of node availability under high load and might compromise application performance or functionality.
