I disagree, D seems like overkill for just testing an update.

Wait, can you really split traffic with a new VPC? Sounds complicated.

Option B is the best choice for canary testing!

I recall we discussed deploying new versions in App Engine, but I can't remember if we covered the differences between options B and D. They both mention splitting traffic, right?

I feel like option C is a bit overkill for just testing an update. Using a new VPC seems unnecessary when we can split traffic directly in App Engine.

I'm not entirely sure, but I remember something about canary testing. Was that related to option A? It might be a good approach too.

I think option B sounds familiar because we talked about traffic splitting in our last study session. It seems like a safe way to test updates.

Okay, I've got this. The key is to allow the virtual server to connect to the USB drive, so port mapping is the way to go.

Okay, let me think this through. Shrinkage rate is probably about the loss of material or quality during manufacturing or storage, rather than just a reduction in demand. I'll go with option B or D.
