MUX VLAN provides a mechanism for network resource control based on VLANs. Which of the following concepts do not belong to the MUX VLAN?

Question 781

LSRs use various label distribution control modes to set up LSPs. Which of the following statements is false?

There are two label distribution control modes: independent and ordered.

If the label advertisement mode is DU and the label distribution control mode is Independent, an LSR distributes labels without waiting for labels from the downstream device.

If the label advertisement mode is DoD and the label distribution control mode is Independent, the transit device distributes labels only after receiving a label mapping message from the egress device.

If the label advertisement mode is DU and the label distribution control mode is Ordered, the transit LSR distributes labels to the ingress device only after receiving a label mapping message from the egress device.

Question 784

Which of the following statements regarding multicast routing are true? (Choose all that apply.)

A multicast routing protocol is used to create and maintain multicast routes, and to forward multicast data packets correctly and efficiently.

Multicast routes form a unidirectional loop-free data transmission path from a data source to multiple receivers. This transmission path is a multicast distribution tree.

Multicast routing protocols can be divided into intra-domain and inter-domain multicast routing protocols.

The multicast routing protocol includes the IGMP protocol.
