When DCI links are used to extend Layer 2, what must you ensure is configured to prevent broadcast storms?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
STP or a loop prevention mechanism on the bridged interfaces.
L2 extension requires loop prevention mechanisms like BPDU guard or storm control.
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 all interfaces to 'trunk' mode.
Why it's wrong here
Trunking doesn't prevent broadcast storms.
- ✗
Increase the MTU size.
Why it's wrong here
MTU affects fragmentation, not broadcast storm prevention.
- ✗
Disable OMP for the L2 interfaces.
Why it's wrong here
OMP manages L3 routes, not L2 bridging.
- ✓
STP or a loop prevention mechanism on the bridged interfaces.
Why this is correct
Bridging L2 traffic requires loop prevention to avoid broadcast storms.
