Which of the following statements regarding the designated router (DR) are true? (Choose all that apply.)

In DR election on a network segment, if two routers have the same DR priority, the one with a larger IP address wins.

The receiver DR sends Join messages to the multicast source or RP.

The assert winner on a shared network segment may not be the DR on the network segment.

In DR election on a network segment, if two routers have the same DR priority, the one with a larger IP address wins.

The source DR sends Register messages to the RP by multicast.

The receiver DR sends Join messages to the multicast source or RP.

The assert winner on a shared network segment may not be the DR on the network segment.

On a campus network, the gateway is usually configured on the aggregation layer. What advantages does this design have compared with configuring the gateway on the access layer? (Choose all that apply.)

Properly design the Layer 2 network scale, reduce network segment allocation, and improve network management efficiency.

Allow configuring access devices as Layer 2 devices, reducing network construction costs.

Reduce the broadcast domain on the network and the probability of broadcast storms.

Achieve separate convergence of Layer 2 and Layer 3 to increase the convergence speed and network stability.

Properly design the Layer 2 network scale, reduce network segment allocation, and improve network management efficiency.

Allow configuring access devices as Layer 2 devices, reducing network construction costs.

Leverage the STP and VRRP mechanisms to improve network reliability.
