Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The subnet CIDR ranges overlap.
Why this is correct
Overlapping subnets result in an INACTIVE peering state.
- ✗
The IAM permissions for the peer are insufficient.
Why it's wrong here
IAM permissions are not checked for peering state.
- ✗
The dynamic routing mode differs.
Why it's wrong here
Different routing modes do not cause INACTIVE state; they affect route propagation.

Why it's wrong here
Firewall rules do not affect peering state; they only control traffic.
