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

802.1X Authentication
Why it's wrong here
Used for network access control, not DHCP forwarding.
- ✓
IP Helper Address
Why this is correct
This forwards the DHCP broadcast to the designated server.

Snooping is a security feature to prevent rogue servers, not for forwarding.
