Question 101

Regarding the basic concepts of MSTP, the correct statement is

A.CIST is a tree calculated by all switches in the network, and its root is the total root in the network

B.The common root of CIST is the switch with the smallest bridge ID among all switches in the network

C.The regional root of CIST is the root bridge of IST in a certain region

D.The domain root of CIST refers to the switch with the highest priority in a certain domain

Question 102

There are multiple IGMPv2 group member hosts (Client1/Client2/Client3) in the shared network segment, and multiple IGMPv2 routers (Router1/Router2), as shown in the following figure:
192.168.207.254 192.168.207.253
Router1 Router2
+++++
Clientl Client2 Client3
192.168.207.1 192.168.207.2192.168.207.3
So, the following statement is correct

A.Only Router1 periodically sends general group queries to the shared network segment

B.After the host receives the query message, only Clients send the Report message

C.After the host receives the general group query message, after the first host sends the Report message, the other hosts' Report messages are suppressed

D.Routerl and Router2 periodically send general group queries to the shared network segment

E.Only Router2 periodically sends general group queries to the shared network segment

F.After the host receives the general group query message, Client1, Client2, and Client3 may all send Report messages

Question 103

Routers running PIM-DM will periodically send Hello messages to discover neighbors, establish and maintain neighbor relationships. The following descriptions of Hello messages are correct. __

A.When the router runs IGMPV2, the DR is elected for the shared network segment through the PIMHello message, and the DR serves as the Querier of IGMP

B.If Hello messages have the same priority, the router with the larger interface IP address will become the DR

C.All PIM routers are members of the 224.0.0.13 multicast group

D.The router sends PIM Hello in multicast mode, the destination address is 224.0.0.13

E.When the DR is elected, the router with the higher priority of the Hello message will become the DR

Question 104

Two routers RTA and RTB are connected through a LAN to form a VRRP backup group. The interface configuration of each router is as follows:
GigabitEthernet1/0 of RTA
ip address 192.168.0.252 255.255.255.0
ip address 192.168.1.252 255.255.255.0 sub
vrrp vrid 1 virtual-ip 192.168.0.254
vrrp vrid 1 priority 120
vrrp vrid 2 virtual-ip 192.168.1.254
GigabitEthernet1/0 of RTB
ip address 192.168.0.253 255.255.255.0
ip address 192.168.1.253 255.255.255.0 sub
vrrp vrid 1 virtual-ip 192.168.0.254
vrrp vrid 2 virtual-ip 192.168.1.254
vrrp vrid 2 priority 120
From the above information-know

A.Router A is the master router of backup group 1, and router B is the master router of backup group 2.

B.Router A is the master router of backup group 1, and backup group 2 has no master router

C.Backup group 1 can be successfully established, and backup group 2 can be successfully established

D.Backup group 1 can be successfully established, but backup group 2 cannot be successfully established

Question 105

The customer's two routers are connected together through a LAN, and the two routers form a VRRP backup group and the related configuration is as follows:
[RTA-GigabitEthernet1 /0]display this
ip address 192.168.0.252 255.255.255.0
vrrp vrid 1 virtual-ip 192.168.0.254
vrrp vrid 1 priority 120
[RTB-GigabitEthernet1/0]display this
ip address 192.168.0.253 255.255.255.0
vrrp vrid 1 virtual-ip 192.168.0.254
RTA router GigabitEthernet1/0 interface MAC is 000f-4300-0001, RTB router GigabitEthernet1/0 interface MAC is 000f-4300-0002 If RTA adopts aggregation group Real-mac mode, RTB adopts aggregation group virtual-mac mode, from the above information Learned

A.If the gateway MAC received by the LAN PC is 0000-5e00-0101, the router RTB is in the VRRP Master state

B.The gateway MAC received by the LAN PC is 000f-4300-0001

C.RTA and RTB cannot establish VRRP group

D.The gateway MAC received by the LAN PC is 0000-5e00-0101
