[All Professional Cloud DevOps Engineer Questions]

You support a stateless web-based API that is deployed on a single Compute Engine instance in the europe-west2-a zone . The Service Level Indicator (SLI) for service availability is below the specified Service Level Objective (SLO). A postmortem has revealed that requests to the API regularly time out. The time outs are due to the API having a high number of requests and running out memory. You want to improve service availability. What should you do?

I’m surprised the API is running out of memory on a single instance!

Wait, can we really fix this just by adding more instances?

Changing the SLO? That's just lowering the bar.

I think load balancing is the way to go!

Moving to higher-spec instances sounds like a solid plan.

D sounds tempting for failover, but I wonder if it would actually improve availability during high traffic. I think we practiced something similar in class, but I can't remember the specifics.

I feel like changing the SLO to match the SLI, like option A suggests, is just a workaround and not a real fix. But I can't recall if that's ever a good practice.

I think C might be the way to go since it mentions load balancing, which could really help with high traffic. I just hope I remember the details about setting that up correctly.

I remember we discussed how increasing memory could help with timeouts, so B seems like a good option, but I'm not sure if it's the best long-term solution.

I'm a bit confused by this question. Is the answer really that straightforward, or is there some nuance I'm missing? I'll need to re-read the question and options carefully.

Okay, let's see here. The options mention "Queues Activity," "Queues Performance," "My Queues Activity," and just "Queues." I'm thinking the "Queues Performance" view might be the one that shows the current metrics and information for members.
