  The best solution is B: Create a custom route with a more specific route than the system-generated one, and use a tag applied to instance-A. This ensures that only instance-A's traffic routes through instance-B without affecting other traffic within the subnet.

• Chose B1

  The answer is B. Lots of discussion about whether you can create a more specific route and whether the tag is necessary. The answer is somewhat in the question: Yes, use a tag applied to instance-A because it allows you to apply the more specific route to just the instance(s) with that tag. The question doesn't say ALL instances in the subnet, just instance-A. As for creating a more specific route: Yes, you can do this and while the documentation is somewhat confusing on this topic, you only need to focus on the static route documentation to be sure: https://cloud.google.com/vpc/docs/static-routes

  At first, I agreed that the answer was A. However, on further reflection, I think this is a "Gotcha" question. While the question doesn't specify "Only instance-A," it also doesn't specify the entire subnet. Answer A would route the *entire subnet*, including instance-A, while Answer B could route *just instance-A.* tl;dr: this is a badly worded question that could be answered multiple ways.
