Use the show route 77.0.0.1 command on Node device LC0.

B.

Use the show route table inet.0 command on Node device LC0.

C.

Use the show route fabric table default.bridgevpn.0 77.0.0/24 extensive command on Node device LC0.

D.

Use the show route fabric table default.inet.0 77.0.0/24 extensive command on Node device LC0.

 

Answer: D

Referring to the exhibit, which statement is true?

 

A.

The configuration file will commit and will treat RSNG-1:ae47 as an access port associated with the default VLAN.

B.

The configuration file will not commit because of the limited number of aggregated interfaces associated with the network Node group.

C.

The configuration file will not commit because RSNG-1:ae47 is configured as an access port and is associated with multiple VLANs.
