Question 541

Compared to IPV4 multicast, which of the following descriptions is the characteristic of IP6 multicast?

IPv6 multicast does not contain MSDP and dense mode

The first 8bit IPV6 multicast address is always FF(11111111).

IPv6 multicast clients use IGMPv3 to join multicast groups

IPv6 multicast load sharing extends the multicast routing rules and is completely independent of RPF check

Question 544

What is the significance of reserved multicast address 224000~22400255?

The multicast address range is reserved for the management of multicast addresses, and is valid locally

The address identifies Global lnternet, and the address range is valid for the entire network

This multicast address range is reserved for the management of multicast addresses, which cannot transmit multicast traffic to the Internet

Any legitimate multicast traffic and multicast application Junhui adopts an address change

The multicast address range is reserved for link-local multicast traffic, including network control messages, and the address range is only valid locally

Question 545

Regarding the WRR (Weight Round Robin) description of the error is ?( Multiple select).

WRR avoids congestion in the network

WRR guarantees that various queues are allocated to a certain amount of bandwidth

WRR is a congestion management technique

WRR can no longer use

WRR on GE interfaces to ensure that critical services are prioritized for

Question 546

Why is BGP an enhanced distance vector routing protocol?

According to the routing rules of BGP routing, the route with lower MED is preferred

BGP uses the ASPATH attribute to record all autonomous system numbers that a route passes through into an AS list, and based on that attribute, routes with shorter AS-PATH are preferred

NEXT_HOP is a recognized mandatory attribute

BGP cannot accept routes that carry a local AS number in the AS_PATH

Question 547

Which of the following options is correct?

Unicast and broadcasting cannot effectively achieve data transmission between one source and multiple destinations on P2MP, but multicast technology can

Multicast technology is able to reduce redundant traffic, so network bandwidth can be saved C.Multicast technology is used for "-to-many" applications

Since multicast is based on TCP to establish a connection, multicast technology can ensure the reliable transmission of data

Question 548

What is the exact description of the SSM features?

Using SSM, the receiver can use INCLUDE in IGMPv3 to indicate that the source

SSM he wishes to join is an extension of the DVMP protocol. to efficiently transmit one-to-many communication traffic

SSM requires MSDP to discover active sources in other PIM domains

Routing multicast traffic in the SSM is done by relying on the number of sources, and the RP is used for the receiver to answer the corresponding number of sources
