CompTIA Cloud+ (CV0-003) — Question 73

A cloud engineer is performing updates to an application and needs to gracefully stop any new transactions from processing before the updates can be applied. Which of the following steps should the engineer take?

Answer options

• A. Enable maintenance mode from the application dashboard
• B. Wait until after business hours to conduct the change when the system is not in use
• C. Run a kill command on the system to stop the application services
• D. Use a load balancer to redirect traffic to other systems serving the application

Correct answer: D

Explanation

The correct answer is D because using a load balancer allows the engineer to redirect incoming traffic to other servers, effectively preventing new transactions while updates are applied. Options A and B do not directly prevent new transactions from being processed, and option C is disruptive and not a graceful method of stopping transactions.
