Google Professional Cloud DevOps Engineer Exam - Topic 6 Question 61 Discussion

You are investigating issues in your production application that runs on Google Kubernetes Engine (GKE). You determined that the source Of the issue is a recently updated container image, although the exact change in code was not identified. The deployment is currently pointing to the latest tag. You need to update your cluster to run a version of the container that functions as intended. What should you do?
D) Alter the deployment to point to the sha2 56 digest of the previously working container.
A) Create a new tag called stable that points to the previously working container, and change the deployment to point to the new tag.
B) Apply the latest tag to the previous container image, and do a rolling update on the deployment.
C) Build a new container from a previous Git tag, and do a rolling update on the deployment to the new container.

Wait, can we really just revert to a previous Git tag like that?

I think building a new container from a previous Git tag might be overkill. Isn't there a simpler way to just point to the previous image?

I feel like we practiced a question similar to this where we had to revert to a previous version. Was it about using the sha256 digest?

I'm not entirely sure, but I think creating a stable tag could be a good option. It seems like a safer way to revert.

I think I've got a good handle on this. Option C seems like the most straightforward way to revert to a known working version. I'll make sure to test it thoroughly before applying the changes to the production environment.

Option D looks interesting - altering the deployment to point to the previous container's SHA-256 digest. I wonder if that would be a more reliable way to revert to a working version. I'll have to research that a bit more.

Hmm, I'm a bit unsure about this one. I'm considering option A, creating a new "stable" tag, but I'm not sure if that's the best approach. I'll have to think it through carefully.

This seems like a straightforward question. I think I'll go with option C - building a new container from a previous Git tag and doing a rolling update on the deployment. That way, I can easily revert to a known working version without having to create a new tag.

This looks like a straightforward question about the types of variables used in discovery patterns. I'll need to carefully review the options and choose the three that best fit the description.

This is a good question to test our understanding of FC fabric security. WWPN zoning is definitely the way to go, and VLAN is a smart choice to add an extra layer of isolation. I feel confident about these two options.

This is a good test of our understanding of Power BI security features. I think option B, where we have the Azure network security team create security groups and then configure RLS to use those groups, is the best approach to meet the requirements.

Okay, I've got this. Services are enterprise-centric because the service-orientation approach is focused on aligning IT capabilities with business needs and requirements. I'll select the answer that best captures this idea.

I don't know, I'm kind of leaning towards option D. Pointing to the SHA256 digest seems like it might be a bit more robust, you know? It's not dependent on tags or anything like that. But I can see the appeal of C as well. Tough call.

Haha, can you imagine if we tried option B? 'Apply the latest tag to the previous container image'? That's like trying to put a fresh coat of paint on a broken-down car and expecting it to run better. No, I think C is the way to go. Keep it simple, you know?

Yeah, I agree with you there. Option C seems like the most straightforward approach. We know the previous version was working, so let's just build a new container from that and swap it in. I'm not a big fan of the other options - they seem like they might introduce more complexity than necessary.

Hmm, this is a tricky one. I'm not sure if I fully understand the context here. But from what I can gather, it seems like we need to revert to a previous, working version of the container image. I think option C might be the way to go - building a new container from a previous Git tag and doing a rolling update on the deployment.
