Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It separates policing actions strictly for Layer 2 control frames
Why it's wrong here
Control frames are handled by separate routing-protocol filters.
- ✓
It shares a single policer bucket across all forwarding classes on the logical interface
Why this is correct
It enforces rate limits across the entire logical interface aggregate.
- ✗
It disables hardware-based policing and falls back to RE software rate-limiting
Why it's wrong here
Logical interface policers execute in hardware on supported ASICs.
- ✗

Why it's wrong here
