Which of the following sets of commands CANNOT be included in the plan to implement HSRP on a Layer 3 switch port?

A. interface port-channel no switchport

B. interface fastethernet no switchportip address

C. interface fastethernet switchport mode access

D. interface vlan ip address








 

Suggested Answer: C

The following set of commands cannot be included in the implementation plan to configure HSRP on a Layer 3 switch port: interface fastethernet switchport mode access
This set of commands creates an access port on the switch. The access port can then be assigned to a VLAN. HSRP cannot be enabled on access ports. To enable HSRP on a switch port, the port has to be any of the following:
EtherChannel port Refers to a Layer 3 switch port used for EtherChannel
Routed port Refers to a Layer 3 port on a switch used for routing
Switch virtual interface (SVI) Refers to a Layer 2 switch port used for inter-VLAN routing
The interface port-channel and no switchport commands allow you to create a Layer 3 port-channel interface, which can be logically bound with other port-channel interfaces to form an EtherChannel. Port-channel interfaces can be configured as either Layer 2 or Layer 3 interfaces. The interface port-channel command is used to create a Layer 3 port-channel interface.
The following set of commands creates a routed port:
interface fastethernet
no switchport
ip address
Routed ports are physical Layer 3 interfaces that allow you to configure a switch as a router. The no switchport command allows the port to be used purely as a
Layer 3 port. This command restarts the port thereby deleting any Layer 2 configuration settings on the switch.
The following set of commands is used to create an SVI, which is a logical interface that allows you to enable inter-VLAN routing on Layer 3 switches: interface vlan ip address
SVIs are configured as VLAN interfaces and have at least one physical interface assigned to the VLANs.
