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?

Increasing the max to 6 won't fix the AZ issue.

Changing to scale based on requests could help with traffic spikes.

Surprised the AZs went down completely!

I disagree, scaling by requests might be better.

Increasing the minimum to 2 seems smart.

Increasing the maximum to 6 seems like it could help, but I wonder if that really addresses the underlying issue. Not sure about option D.

I practiced a similar question where reducing AZs actually led to more downtime. So, I don't think option C is the right move here.

I'm not entirely sure, but I think scaling based on requests might help with load balancing. Option B could be a good choice, but I need to think more about it.

I remember we discussed how increasing the minimum servers could help maintain availability during an AZ failure. So, option A sounds reasonable.

This is a tricky one, but I think I have a good strategy. Decreasing the number of AZs could reduce the impact of an AZ failure, so I'll go with option C.

I'm a little confused by this question. Scaling based on CPU usage seems like a good approach, but I'm not sure if changing the scaling metric is the right solution here. I'll need to re-read the question carefully.

Okay, I think I've got this. The key is to spread the instances across more Availability Zones to reduce the impact of a single AZ going down. I'll go with option A.

Hmm, I'm a bit unsure about this one. Increasing the minimum number of servers could help, but I'm not sure if that's the best approach. I'll need to think it through.

Hmm, I'm a bit unsure about this one. I'll need to review the OSPF Router ID details again.

This seems like a straightforward question about resource management. Based on the details provided, the approach being described is likely used to identify resource capacity and capability, which is crucial for making the case for acquiring new resources.

Wait, did the question say the AZ went down, or the IT associate? Either way, I hope they have a backup plan, like a cup of coffee and a good sense of humor.

Increasing the maximum to 6? That's overkill, unless we're planning to host the entire internet on this app.

Decreasing the AZs to 2? That's risky, we might as well put all our eggs in one basket!

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.
