Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

set system authentication-key <key>
Why it's wrong here
This sets global system authentication, not per-peer MSDP TCP authentication.

Why it's wrong here
MSDP authentication is configured under protocols msdp, not protocols pim.
- ✓
