Correct answer & explanation
✓
Hashing algorithm
IKE Crypto Profiles define encryption algorithms, hashing algorithms, and Diffie-Hellman groups for Phase 1.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Tunnel interface IP
Why it's wrong here
Not a crypto profile setting.
