Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Excess traffic exceeding the threshold is dropped by the switch hardware.
Why this is correct
Storm control drops traffic that exceeds the defined rate limit until levels subside.
- ✗
Traffic is rate-shaped and buffered in the output queue until congestion clears.
Why it's wrong here
Storm control typically polices (drops) traffic rather than shaping or buffering ingress broadcast floods.
- ✗
The interface is immediately shut down and placed in an error-disabled state.
Why it's wrong here
Shutting down is a port security violation action, not the default storm control action (which drops excess traffic).
- ✗
The switch sends SNMP traps and forwards the traffic with a low-priority CoS marking.
Why it's wrong here
Storm control drops the traffic rather than remarking and forwarding it.
