H3CSE-RS-SW Sample Questions:
In the switching network shown in the figure, VLAN10 is set as isolate-user-vlan on switch SWA, VLAN2 and VLAN3 are secondary VLANs of VLAN 10; VLAN2-VLAN20 is created on switch SWB, and VLAN20 is set as isolate-user-vlan, and VLAN4 is the secondary VLA of VLAN20. After setting the IP addresses of each device as shown in the figure, which of the following statement is correct?
- A. When SWB accesses PCA, the message from SWB's GigabitEth1/0/4 does not carry a VLAN Tag
- B. PCA's message comes out of SWA's GigabitEthem1/0/3 port and enters SWB's GigabitEthem1/0/4 port. The VLAN tag it carries is VLAN 10.
- C. The PCA message enters from the GigabitEthem1/0/1 port of SWA and comes out from the GigabitEthem1/0/3 port with the VLAN Tag VLAN 1
- D. SWB's message enters from SWA's GigabitEthem1/0/3 port and leaves from GigabitEthem1/0/1 port with the VLAN tag VLAN10.
Correct Answer: A 🗳️
Which of the following multicast group management protocols can support the SSM model?
(Multiple choice)
- A. MLDvl
- B. IGMPV2
- C. IGMPV3
- D. IGMPvl
- E. MLDV2
Correct Answer: C,E 🗳️
PIM-DM provides a state refresh mechanism. Which of the following statements are correct?
(Multiple choice)
- A. The router will reset the pruning timer after receiving the State Refresh message
- B. The router directly connected to the receiver sends a State Refresh message
- C. When the interface is in pruning state, the pruning flag in the State Refresh message is 1
- D. When the interface is in forwarding state, the prune flag in the State Refresh message is 0
- E. After receiving the State Refresh message, the router sends a State Refresh message to the interfaces of all PIM neighbors.
Correct Answer: A,C,D 🗳️
Regarding loop protection, which of the following is correct? (Multiple choice)
- A. In MSTP, this function is valid for root ports, alternate ports, and backup ports.
- B. If the role of the root port changes, it will change to the Discarding state and will not forward messages, so as not to form a loop in the network. The Discarding state will be maintained until the port receives a BPDU again and becomes a root port again.
- C. After the loop protection function is enabled, when the BPDU stored on the port ages, the loop protection takes effect.
- D. Link blocking or one-way link may cause loops
Correct Answer: A,B,C,D 🗳️
The figure shows the stable topology after STP calculation convergence. Which of the following statements is correct? (Multiple choice)
- A. This BPDU is a configuration BPDU, and the destination address is 01-80-C2-00-00-0
- B. The aging time for the port to save the BPDU is MaxAge
- C. The sending period of this BPDU is HelloTime
- D. SWA is the root bridge in the network
Correct Answer: A,B,C,D 🗳️
