MSTP uses slacked VLAN tags to extend a Layer 2 Ethernet connection between multiple sites

NEW QUESTION 16

Referring to the exhibit, there are multiple ASM groups in the 224.0.0.0/4 range.
Which configuration change is needed to ensure R1 is always the RP for group 224.224.1.1?

Set the priority on R1 to zero.

Increase the priority on R1 to higher than R2.

Configure R1 with a higher local RP address.

Ensure R1 has a more specific group range.

NEW QUESTION 17
Packets enter a Juniper device and are classified as best effort. During the processing of the packet, the classification of the packets is changed to expedited forwarding by a multi-field classifier. The device is using the default CoS policies Which statement is true in this scenario?

The packet is forwarded according to the new packet classification, and the DSCP bits are rewritten to the new class.

The packet is forwarded according to the new packet classification, and the DSCP bits do not change.

The packet is forwarded according to the original packet classification, and the DSCP bits do not change.

The packet is forwarded according to the original packet classification, and the DSCP bits are rewritten to the new class.

NEW QUESTION 18
