문제4

The following statement about the three-layer switch is correct.

A. The Layer 3 switch contains two parts: a Layer 2 VLAN forwarding engine and a Layer 3 forwarding engine

B. The three-layer switch functionally realizes the division of VLANs, the two-layer switching within the VLAN and the functions of inter-VLAN routing

C. The three-layer forwarding engine of the three-layer switch is equivalent to the function of the router in the traditional networking, using hardware ASIC technology to realize the three-layer routing and forwarding across network segments

정답: A,B,C,D

문제5

Regarding priority mapping and priority trust, there are correct statements

A. After the packet enters the switch port, it will enter the queue according to the priority of 802.1P by default

B. After the packet enters the switch, if you want to queue according to the 802.1P or DSCP value, you must configure the port to trust 802.1P or DSCP

C. After the packet enters the switch port, it will enter the queue according to the priority of DSCP by default

D. After the message enters the switch port, it will enter the queue according to the priority of the port by default

정답: B,D

문제6

As shown in the network, the switch enables RSTP, assuming that the cost of each link is the same, the following statements are correct:

A. If the SWD port EO/1 is down, the SWD port E0/2 will immediately change from the Alternate port to the new root port

B. Assuming that the spanning tree operating mode of SWB and SWC is modified to STP, the Alternate port of SWD can still enter the forwarding state directly after it becomes the new root port

C. If there are multiple alternate ports on the SWD, when the root port is down, SWD will select the port with the highest priority from these alternate ports as the new root port

D. After topology convergence, SWD will have one port as an alternate port

정답: C,D

문제7

D. -There can only be one C-RP in a PIMSM domain

정답: C

문제10

The customer LAN switches SWA, SWB, and SWC form the RRPP ring main ring 1, and the switch SWA has the following configuration information:
[SWA] rrpp domain 1
[SWA-rrpp-domain1] control-vlan 4092
If the switch SWA ports Gigabitethernet 1/0/1 and Gigabitethernet 1/0/2 are connected to the RRPP ring, we can know from the above information

A. If SWA is the master node, when the R&PP ring is in a healthy state, the SWA secondary port only allows VLAN4092 to pass

B. If SWA is a transit node, when the RRPP ring is in a healthy state, the SWA main port only allows VLAN4092 to pass

C. If SWA is the master node, the functions of GigabitEthernet 1/0/1 and GigabitEthem 1/0/ 1/0/2 are the same

D. If SWA is a transmission node, the functions of Gigabitethernet1/0/1 and Gigabitethernet1/0/2 are the same

정답: A,D

문제11

In the switching network as shown in the figure, all three switches have only default VLAN1. The interconnection ports of the three switches are Trunks, and all VLANs are allowed to pass. All three switches have the global and port GVRP functions enabled. VLAN 10 is created on the switch SWA, VLAN 20 is created on the switch SWC, and the GVRP registration mode of the Ethernet1/0/1 port is set to Forbidden on the switch SWA. Check the status of each Trunk port on the three switches. (Choose one or more)

A. [SWB]display interface Ethernet 1/0/1 Ethernet1/0/1 current state: UP ...... PVID: 1 Mdi type: auto Link delay is 0(sec) Port link-type: trunk VLAN passing: 1 (default vlan), VLAN permitted: 1 (default vlan), 2-4094 Trunk port encapsulation: IEEE 802.1q

문제12

Regarding loop protection, the following statements are correct

A. After the loop protection function is activated, when the BPDU saved on the port ages, the loop protection takes effect

B. Link congestion or single link may cause loops

C. If the role of the root port changes, it will become the Discarding state, without forwarding packets, so that no loop will be formed in the network. The Discarding state will be maintained until the port receives the BPDU again and becomes the root port again.
