Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Port priority (low, high, critical)
Why this is correct
Port priority can be configured per interface to determine power shedding order.
- ✓
Disabling PoE on a specific interface
Why this is correct
PoE can be disabled on individual ports using interface-level configurations.
- ✗
Dynamic voltage step-down thresholds based on cable length
Why it's wrong here
Voltage step-down based on cable length is not a configurable Junos PoE feature.
- ✗
Automatic cable resistance compensation profiling
Why it's wrong here
Cable resistance profiling is handled by hardware physical layer auto-calibration, not manual CLI configuration.
- ✓
Maximum power limit in watts or milliwatts
Why this is correct
Administrators can restrict the maximum power a specific port can deliver.
