A user is attempting to watch a high-definition video being streamed from the media server over the network. However, the user complains that the experienced video quality is poor. While logged on to router B, a Juniper Networks device, you notice that video packets are being dropped.
In this scenario, what would solve this problem?

  • A. Adjust the scheduler for the expedited-forwarding forwarding class to support a higher transmit rate.
  • B. Adjust the expedited-forwarding BA classifier to router B's ge-0/0/0 interface to support a higher transmit rate.
  • C. Adjust the scheduler-map to support a higher transmit rate.
  • D. Adjust the expedited-forwarding BA classifier on router B's ge-0/0/1 interface to support a higher transmit rate.


Answer : D

There are two BGP routes to 10.200.200.0/24 received from two external peers. Route 1 comes from a neighbor with a router ID of 10.10.100.1 and a peer IP address of 10.10.30.1, and route 2 comes from a neighbor with a router ID of 10.10.200.1 and a peer IP address of 10.10.50.1. Both routes have the same MED value, origin value, AS path length, and local preference number.
In this scenario, which statement is correct about the active route?

  • A. Route 1 will be active because of the peer IP address.
  • B. Route 2 will be active because of the peer IP address.
  • C. Route 1 will be active because of the router ID.
  • D. Route 2 will be active because of the router ID.


Answer : D

  • B. multiple supplicant mode
  • C. single-secure supplicant mode
  • D. MAC authentication mode
