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
✓
interval 150 ms, min_rx 150 ms, multiplier 3
If no BFD timers are configured under the interface, the default values are: interval = 150 ms, min_rx = 150 ms, multiplier = 3. These are the defaults used when 'bfd interval' is not specified.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
interval 100 ms, min_rx 100 ms, multiplier 3
Why it's wrong here
These are not the defaults; 100 ms is a common configured value but not default.
- ✓
interval 150 ms, min_rx 150 ms, multiplier 3
Why this is correct
Correct. The default BFD timers on Cisco IOS-XE are 150 ms interval, 150 ms min_rx, and multiplier 3.
- ✗
interval 200 ms, min_rx 200 ms, multiplier 5
Why it's wrong here
These are not the default values.
- ✗
interval 50 ms, min_rx 50 ms, multiplier 3
Why it's wrong here
50 ms is too low for default; it is a common custom value.
