A port in a redundant topology is currently in the blocking state and is not receiving BPDUs. To ensure that this port does not erroneously transition to the forwarding state,
which command should be configured to satisfy the requirement?()

B.BPDU filter configured on a link to another switch
C.Spanning Tree Protocol enabled on both Layer 2 and multilayer switches
D.PortFast enabled on all access and trunk ports

B.Configuration changes made on a physical port that is a member of a port-channel interface apply to the port-channel interface.

A.By default, native VLAN packets going out this port will be tagged.
B.Without an encapsulation command, 802.1Q will be the default encapsulation if DTP fails to negotiate a trunking protocol.
C.The interface will support the reception of tagged and untagged traffic.
D.If the device connected to this port is not 802.1Q-enabled, it will not be able to handle 802.1Q packets.
