• Question 161:

  You are asked to associate the v100 and v200 VLANs with the ge-0/0/1 interface. Which two configurations are correct? (Choose two.)

  A. {master:0}[edit] user@switch# show interfaces ge-0/0/1 unit 0 { family ethernet-switching { vlan { members [ v100 v200 ]; } } }

  B. {master:0}[edit] user@switch# show interfaces ge-0/0/1 unit 0 { family ethernet-switching { port-mode trunk; vlan { members [ v100 v200 ]; } } }

  C. {master:0}[edit] user@switch# show vlans v100 { vlan-id 100; interface { ge-0/0/1.0; } } v200 { vlan-id 200; interface { ge-0/0/1.0; } }

  D. {master:0}[edit] user@switch# show vlans v100 { vlan-id 100; l3-interface ge-0/0/1.0; } v200 { vlan-id 200; l3-interface ge-0/0/1.0; }

  A.

  The software is ignoring the fbf routing instance because it uses a reserved name.

  B.

  The software is ignoring the default route in the fbf routing instance because there is no default route in the main routing instance.

  C.

  The software is not able to find an interface on the router configured with the 10.210.12.129 address.

  D.

  The software is not able to resolve the next hop of the default route in the fbf routing instance.

  Correct Answer: D
