TURE

FALSE

NEW QUESTION 291
An engineer uses two routers to test IPv6 services, and simulates the interconnection between headquarters and branches by running BGP4+.

The logical topology of the network is shown in the figure. Regarding the transmission of IPv6 routes between two devices, which of the following statements is wrong?

When routing is transmitted, it will carry recognized mandatory attributes such as AS_Path

BGP4+ transmits routing information between peers through Update packets

When routing, the Next_Hop attribute must be an IPv6 global unicast address

If the Update message carries the MP_REACH_NLRI attribute, it means that the advertised route is reachable

NEW QUESTION 292
Which of the following descriptions are correct about IGMPv1 and IGMPv2? (Multiple choice)

Both routers need to confirm the two routers after sending them. Otherwise, they need to be retransmitted.

The master-slave relationship in the DD packet exchange of OSPFA is not bound to the DR/BDR. The CSNP packet is generated only by the DIS.

Once the adjacency relationship is established, CSNP packets and DD packets will stop sending.

The two routers do not need to confirm the peer router after sending.

NEW QUESTION 294

The PIM Join message is only sent when the multicast tree is established for the first time

The PIM Join message is sent every 60 seconds to refresh the status of the upstream router mroute for the multicast tree

The upstream router sends a PIM Join confirmation in response to each PIM Join message received from the downstream router

NEW QUESTION 295
What improvements have been made to the IGMPv2 protocol compared to IGMPv1? (Multiple Choice)

Added maximum response time field

Added specific source group query messages

NEW QUESTION 296
The correct description in the following of BGP loop protection is: (Multiple Choice)
