Google Professional Cloud DevOps Engineer Exam - Topic 1 Question 18 Discussion

You support a production service that runs on a single Compute Engine instance. You regularly need to spend time on recreating the service by deleting the crashing instance and creating a new instance based on the relevant image. You want to reduce the time spent performing manual operations while following Site Reliability Engineering principles. What should you do?
A) File a bug with the development team so they can find the root cause of the crashing instance.
B) Create a Managed Instance Group with a single instance and use health checks to determine the system status.
C) Add a Load Balancer in front of the Compute Engine instance and use health checks to determine the system status.
D) Create a Stackdriver Monitoring dashboard with SMS alerts to be able to start recreating the crashed instance promptly after it has crashed.

D sounds like a band-aid solution, not a fix.

Health checks are a must, so B or C makes sense.

Surprised that filing a bug (Option A) is even an option here.

I disagree, a Load Balancer (Option C) is more effective for scaling.

Option B is the way to go! Managed Instance Groups are super helpful.

Option D seems like a reactive approach. I’d rather have something proactive like option B to avoid the crashes in the first place.

I remember practicing a question like this where we discussed using a Load Balancer. But I feel like that might be overkill for a single instance.

I'm not entirely sure about the health checks part. Do they really help with just one instance, or is it more effective with multiple?

I think option B sounds familiar. Managed Instance Groups can automatically recreate instances, which aligns with SRE principles.

I think the best approach here is to ask open-ended questions that allow Mr. Moore to express his thoughts more freely, without pressuring him for a detailed or well-organized response. That way, we can get a better sense of his understanding without making him feel uncomfortable.

Always check for cloud configurations in AEM questions - Analytics seems like the most direct way to manage tracking pixels.

The itsi_summary index sounds promising. That's probably where I'd start looking for ITSI-specific error messages.

I think PTAs give customers more control over their funds, right? Like being able to manage transactions directly with the correspondent bank?

Hmm, I'm a bit unsure here. The question mentions "System Optimization" in WEM, but there are a few different options. I'll need to carefully consider each one to determine which is most relevant for addressing disk contention.
