Which command will display the active configuration?

A. user@router> show configuration

B. user@router# show

C. user@router> show system configuration

D. user@router> show system commit

-- Exhibit -[edit interfaces ge-0/0/1]

user@router# show

unit 100 {

vlan-id 100;

family inet {

address 10.1.1.1 /24;

}

}

[edit interfaces ge-0/0/1]

user@router# commit check

[edit interfaces ge-0/0/1]

'unit 100'

A. You must set the vlan-tagging parameter under the [edit interfaces ge-0/0/1] hierarchy.

B. You must use the rename command to change unit 100 to unit 0.

C. You must set the encapsulation flexible-ethernet-services parameter under the [edit interfaces ge-0/0/1] hierarchy.

D. You must set the encapsulation vlan-ccc parameter under the [edit interfaces ge-0/0/1 unit 100] hierarchy.

-- Exhibit -user@router> show configuration

groups {

ge-int {

B. Apply the ge-int group to the configuration at the [edit interfaces ge-0/0/1] hierarchy.

C. Apply the ge-int group to the configuration at the [edit interfaces ge-0/0/1 unit 0] hierarchy.

D. Apply the ge-int group to the configuration at the [edit interfaces] hierarchy.

Which two statements are true about the primary address on an interface? (Choose two.)

A. It is the address used by default as the local address for broadcast and multicast packets sourced locally and sent out of the interface.

B. You use the primary address when you have multiple IP addresses belonging to the same subnet on the same interface.

C. It can be useful for selecting the local address used for packets sent out of unnumbered interfaces when multiple non-127 addresses are configured on the loopback interface.

D. By default, the primary address on an interface is selected as the numerically highest local address configured on the interface.
