Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Memory exhaustion
Why it's wrong here
Would cause general instability, not specific blockages.
- ✓
Implicit Deny policy
Why this is correct
If no explicit allow rule matches, traffic is dropped by the implicit deny.
- ✗

Why it's wrong here
Would show as a handshake failure, not a blocked policy.

BGP path selection error
Why it's wrong here
BGP doesn't block traffic, it only routes it.
