I think we might need to check the resource quotas first.

Limiting to half sounds smart, good call!

Wait, how do we know the max memory for the namespace?

I think I recall that the request should be set to 160M, but I’m not entirely sure how to determine the limit based on the namespace's max constraint.

I feel a bit confused about the syntax for updating the Deployment. Is it `kubectl edit` or do I need to use `kubectl apply` with a YAML file?

This seems similar to that practice question about resource management we did last week. I think I need to look up the current memory limits for the crayfah namespace first.

I remember we practiced setting resource requests and limits, but I’m not sure how to calculate half the maximum memory constraint for the namespace.

I'm a little confused by the different data sources mentioned. I'll need to make sure I fully understand each one before deciding.

Okay, I think I've got a good handle on this. The key is to identify the factor that wouldn't be relevant in this analysis, like the impact on the current customer base or bank loan covenants. I feel confident I can get this right.

Okay, let's see. The key here is to identify the requirement that is not being addressed in the migration plan. I'll carefully consider each option and try to spot the gap.

My instinct says it's denial of service, but that seems off. It's more about access than service disruption.
