How does a Junos device learn about MAC addresses when II is first connected to an Ethernet LAN?

A. The device sends out a network broadcast message asking tor all devices and MAC addresses on the network and stores this information In addition lo the interface from which the response was received.

B. The device learns the destination MAC addresses from traffic in the network and stores this MAC address in addition to the interface from which the traffic was received.

C. The device learns the source MAC addresses from traffic in the network and stores this MAC address in addition to the interface from which the traffic was received.

D. The device sends out a network multicast message asking for all devices and MAC addresses on the network and stores this Information in addition to the interface from which the response was received.

Which statement describes integrated routing and bridging (IRB) interfaces?

A. An IRB interface Is an IP gateway For hosts of a bridge domain.

B. An IRB interface assigns interfaces to VLANs.

C. An IRB interface enables Layer 2 switching on the router.

D. An IRB interface defines a bridge domain.

Exhibit.

Referring to the exhibit, you have configured an aggregate route that represents the 172.21.0.0/24, 172.21.1.0/24, and 172.21.2.0/24 networks. However, when you view the routing table, your new route hidden.

B. Verify that you have configured a policy on the device to accept aggregate routes.

C. Verify that you have defined a metric value for the aggregate route.

D. Verify that you have set the preference to a lower default value.
