[All LFCA Questions]

An IT associate has a web application running on multiple servers, configured to scale based on CPU usage. The current configuration has a minimum size of 1 and a maximum size of 5 servers, designed to launch and spread the instances across 3 Availability Zones (AZ). During a low utilization period, an entire AZ went down, and the application experienced downtime. What can the IT associate do to increase the availability of the application?

Scaling based on number of requests? Interesting, but what if the requests are low and the CPU usage is still high?

Hmm, increasing the minimum to 2 seems like a good start. At least we'll have a fallback if one AZ goes down.

I think increasing the maximum to 6 servers would provide better redundancy in case of AZ failure.

I disagree, I believe changing to scale based on number of requests would be a better solution.
