Question 1

In the network connection shown in the figure, SWA and SWB are three-layer switches, running STP+VRRP, and after the initial configuration is completed, SWA is the root of STP and the Master of VRRP. SWC is a two-layer switch connected to the terminal. Which of the following description of the network link failure is correct? (Multiple choice)

A. When the link between SWB and SWC is disconnected, the port status on the remaining STP links does not change and remains Forwarding. B. When the link between SWB and SWC is disconnected, the VRRP Master will remain unchanged and the SWC downstream terminal can still communicate normally. C. When only the link between SWB and SWC is intact, SVVA and SWB will become the Master of VRRP, and the lower end of SWC can communicate normally with the gateway. D. When only the link between SWB and SWC is intact, the VRRP Master will remain unchanged, but the SWC downstream terminal cannot communicate with the gateway.

Question 4

The customer has two routers connected through a LAN. The two routers form a VRRP backup group. The relevant 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
The MAC of the GigabitEthernet1/0 interface of the RTA router is 000f-4300-0001, and the MAC of the GigabitEthernet1/0 interface of the RTB router is 000f-4300-0002. If RTA uses the aggregation group Real-mac mode and RTB uses the aggregation group Virtual-mac mode, what can we learn from the above information? (Multiple choice)

A. The gateway MAC received by the LAN PC is 0000-5e00-0101 B. RTA and RTB cannot establish a VRRP group C. If the gateway MAC received by the LAN PC is 0000-5e00-0101, the router RTB is in VRRP Master state D. The gateway MAC received by the LAN PC is 000f-4300-0001

Question 6

As shown in the figure, each switch enables RSTP. Assuming that the link cost values are the same, which of the following is correct? (Multiple choice)

A. If RSTP of both SWB and SWC is cancelled, port EO/2 of SWA will become the backup port. B. If RSTP is disabled on SWB, port EO/1 of SWC will become the root port C. SWB's port E0/1 is an alternate port. D. Network computation convergence does not require waiting for twice the Forward Delay time

Question 7

In PIM-DM networking, which of the following is correct about the router sending the Prune message?

A. After the router interface receives the Prune message, it will no longer send messages of the corresponding multicast group on this interface. B. The party that fails the Assert will send a C. When the outbound interface list in the router (S, G) table is empty, a Prune message is sent to all PIM neighbors. D. When the router has no local directly connected multicast receiver, it sends a Prune message to all PIM neighbors.

1/0/2, Ethernet 1/0/3, and Ethernet 1/0/5 ports to VLAN 10, which of the following is correct? (Multiple choice)

A. [SWA-vlan10] port Ethernet 1/0/1 to 1/0/3 Ethernet1/0/5 B. [SWA-vlan10] port Ethernet 1/0/1 to Ethernet 1/0/3 Ethernet1/0/5 C. [SWA-vlan10] port Ethernet 1/0/1 Ethernet 1/0/2 Ethernet 1/o/3 Ethernet1/0/5 D. [SWA-vlan10] port from Ethernet 1/0/1 to Ethernet 1/0/3 Ethernet1/0/5
