Question 96

In the PIM-DM network as shown in the figure, part of the unicast routing table of routers RT1 and RT2 is as follows:
<RT1>display ip routing-table
Routing Tables: Public
Destination/MaskProtoPreCost NextHop Interface
1.1.0.0/16xxxxP1-1 C1-110.1.1.1POI11
1.1.1.0/24xxxxP1-2 C1-210.1.1.1Port1
<RT2>display ip routing-table
Routing Tables: Public
Destination/MaskProtoPreCost NextHop Interface
1.1.1.0/24XXXX P2-1 C2-111.1.1.1Port2
1.1.1.1/32XXXX P2-2 C2-211.1.1.1Port2
Then, when routers RT1 and RT2 perform Assert, the winner should be

A.If P1-2=P2-2, C1-2<C2-2, RT2 wins

B.If P1-2=P2-2, C1-2=C2-2, RT2 wins

C.If P1-1=P2-2, C1-1<C2-2, RT1 wins

D.If P1-1=P2-2, C1-1=C2-2, RT1 wins

E.If P1-2>P2-2, C1-1<C2-2, RT2 wins

F.If P1-1>P2-2, C1-1<C2-2, RT1 wins

Question 97

The following statements about the PIM SM joining process are correct.

A.If there are still receivers in the shared network segment under the interface where the upstream router receives the pruning message, the receiver will send a group join message

B.As long as the DR has a local receiver of multicast group G, the DR will periodically send join messages upstream

C.When there is no receiver of multicast group G in the DR, the DR will send a pruning message to the upstream router

D.Both PIMSM and PIM DM have a pruning veto process

Question 98

Two routers RTA and RTB are connected through a LAN to form a VRRP backup group. The configuration of each interface is as follows:
GigabitEthernet1/0.1 of RTA
vlan-type dot1 q vid 2
ip address 192.168.0.252 255.255.255.0
vrrp vrid 1 virtual-ip 192.168.0.254
vrrp vrid 1 priority 120
GigabitEthernet1/0.2 of RTA
vlan-type dot1 q vid 3
ip address 192.168.1.252 255.255.255.0
vrrp vrid 2 virtual-ip 192.168.1.254
vrrp vrid 2 priority 120
GigabitEthernet1/0.1 of RTB:
vlan-type dot1 q vid 2
ip address 192.168.0.253 255.255.255.0
vrrp vrid 1 virtual-ip 192.168.0.254
GigabitEthernet1/0.2 of RTB:
vlan-type dot1 q vid 3
ip address 192.168.1.253 255.255.255.0
vrrp vrid 2 virtual-ip 192.168.1.254
The IP addresses of HostA and HostB in the LAN are 192.168.0.1 and 192.168.1.1 respectively. From the above information, we can know

A.If the backup group uses virtual MAC, the gateway MAC addresses learned by HostA and HostB are inconsistent

B.The backup group uses virtual MAC mode, and the gateway MAC addresses learned by HostA and HostB are the same

C.If the backup group uses real MAC mode, the gateway MAC addresses learned by HostA and HostB are inconsistent

D.If the backup group uses real MAC mode, the gateway MAC addresses learned by HostA and HostB are the same

Question 99

Which statement is correct about the communication between switch VLANs?

A.In RSTP, the downstream device will respond to the BPDU with Agreement set only after receiving the BPDU with both Proposa and Agreement set to from the upstream device

B.Both RSTP and MSTP require the designated port of the upstream device to perform rapid migration after receiving the Agreement message from the downstream device

C.By configuring stp no-agreement-check on the port, the MSTP switch will not check whether the Agreement bit is set in the Proposal BPDU sent upstream

D.In the figure, by default, the SWA port E1/0/1 needs to wait twice the duration of the Forward Delay before it can enter the Forwarding state

Question 100

The switches SWA and SWB are connected together through two optical fiber Gigabit Ethernet links, and the switch SWA has the following interface configuration:
[SWA]interface GigabitEthernet 1/0/1
[SWA-GigabitEthernet1/0/1]gvrp
[SWA-GigabitEthernet1/0/1]port link-type trunk
[SWA-GigabitEthernet1/0/1]port trunk permit vlan 1 10
[SWA]interface GigabitEthernet 1/0/2
[SWA-GigabitEthernet1/0/2]port link-type trunk
[SWA-GigabitEthernet1/0/2]port trunk permit vlan 1 10
If you want to configure link aggregation to aggregate these two links together, if the configuration on the SWB is correct, you can know from the above information

A.Only by changing the configuration of GigabitEthe1/0/2 to be consistent with GigabitEthe1/0/1, can they join the same aggregation group

B.Only when GigabitEthernet1/0/2 and Gigabit1/0/1 allow all VLANs to pass, they can join the same aggregation group

C.After link aggregation is configured on SWASWB, if both SWA and SWB enable MSTP on the aggregation port, one of GigabitEthe1/0/1 and GigabitEthe1/0/2 will be blocked

D.After link aggregation is configured on both SWA and SWB, if both SWA and SWB enable MSTP on the aggregation port, GigabitEthernet1/0/1 and GigabitEthe1/0/2 can participate in forwarding
