Why each option

The exhibit shows a storm-control or broadcast suppression configuration on Ethernet 1/1 that fully suppresses all broadcast traffic on that interface.

AAll broadcast traffic is suppressed on Ethernet 1/1.Correct

When storm-control is configured with a broadcast level of 0 or broadcast blocking is enabled on an interface, the switch drops all broadcast frames arriving on that port. This results in complete suppression of broadcast traffic on Ethernet 1/1, which is exactly what the exhibit configuration demonstrates.

BAll broadcast and multicast traffic is allowed on Ethernet 1/1.

The configuration suppresses broadcast traffic rather than allowing it, and multicast suppression is a separate setting that the exhibit does not indicate is disabled.

CAll broadcast traffic is allowed on Ethernet 1/1.

The exhibit shows broadcast traffic being suppressed and dropped, which is the opposite of allowing all broadcast traffic through the interface.

DAll broadcast and multicast traffic is suppressed on Ethernet E1/1.

The configuration shown targets broadcast traffic only; suppressing multicast requires a separate command, and the exhibit does not indicate multicast is also being suppressed.
