CompTIA Cloud+ (CV0-004) — Question 41

A company implements a web farm with 100 servers behind an application load balancer. During scaling events, new web servers that are placed in service have not loaded all their modules, which causes some requests to the web farm to fail. Which of the following should the cloud engineer implement to address the scaling issue?

Answer options

• A. Instance warm-up
• B. Scheduled scaling
• C. Event-based scaling
• D. Load balancer passthrough

Correct answer: A

Explanation

The correct answer is 'Instance warm-up' because it ensures that new servers are fully initialized and ready to handle requests before being added to the load balancer's pool. The other options do not directly address the issue of modules not being loaded on new instances; for example, scheduled scaling and event-based scaling focus on when to add servers rather than ensuring they are ready for traffic.
