Which of the following descriptions about the IP address of the VLAN interface of the H3C three- layer switch is correct? (Multiple choice)
A. When configuring a primary IP address for a VLAN interface, if the interface already has a primary IP address, the original primary IP address must be deleted before configuring a new primary IP address.
B. Before deleting the primary IP address of the VLAN interface, you must first delete the secondary IP address.
C. Only when two or more VLAN interfaces are configured with IP addresses, the switch will have the Layer 3 routing forwarding function.
D. As long as an IP address is configured for a VLAN interface, the switch will have Layer 3 routing and forwarding capabilities.
正解：B,C

質問 2：
Regarding the description of Private VLAN technology and Super VLAN technology, which of the following is correct?
A. Super VLAN technology is also called VLAN aggregation. Its main purpose is to solve the problem of IP address waste or insufficient VLAN interface quantity.

2. When a switch running MSTP and a switch running RSTP work together, which of the following is correct? (Multiple choice)

A) The MSTP switch will regard the RSTP switch as an MSTP domain consisting of a single switch.
B) The MSTP switch will parse the RSTBPDU into an MST BPDU, where IRPC is 0

D) MSTP switches and RSTP switches can belong to the same MST region

3. The customer LAN switches SWA, SWB, and SWC form the RRPP ring main ring 1. The switch SWB has the following configuration information:
[SWB] rrpp domain 1
[SWB-rrpp-domain1] ring 1 node-mode transit primary-port gigabitethernet 2/0/1 secondary-port gigabitethernet 2/0/2 level 0 If switch SWA is the master node of primary ring 1, and if switch SWB port GigabitEthem2/0/1 fails, what can we learn from the above information? (Multiple choice)

A) If switch SWB finds that port GigabitEthernet 2/0/1 is Up again, it will immediately unblock the port.
B) SWA will send a Link-Down message to notify all nodes
C) The switch SWA will send a Common-Flush message to notify all transmission nodes
D) The switch SWA immediately switches to the Failed state and releases the secondary port

4. In the network shown in the figure, the interconnection lines between RT1, RT2, RT3, RT4 and RT5 are all Gigabit Ethernet lines, running OSPF, and the corresponding network segments are released to achieve routing intercommunication. The routers all run the PIM SM protocol, and the RP is 1.1.1.1. RT4 is connected to a receiver, and IGMP is enabled on the corresponding interface. When the multicast traffic initially forwarded along the RPT is switched to the SPT, which of the following routers constitute the SPT? (Multiple choice)

A) RT2
B) RT1
C) RT4
D) RT3
E) RT5

5. The topology is shown in the figure. Perform STP calculation. Which of the following is correct?
(Multiple choice)

A) SWD needs to determine the root port by comparing the ID of the port where it receives the configuration BPDU
B) If the bridge priority of SWD is set to 0, SWD will become the root bridge, and ports E0/1 and E0/2 will both be designated ports.
C) Since the root bridge ID, root path cost, designated bridge ID, and designated port are all the same, the root port of SWD cannot be determined.
D) If the bridge priority of SWD is set to 0, port E0/2 of SWD will only receive configuration BPDUs instead of sending configuration BPDUs
