The switch SWA and SWB are connected together by two optical fiber Gigabit Ethernet links. 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
It can be seen from the above

• A.GigabitEthernet1/0/1 and GigabitEthe1/0/2 cannot join the same aggregation group
• B.Only by changing the configuration of GigabitEthe1/0/2 to be consistent with GigabitEthe1/0/1, can they join the same aggregation group
• C.If MSTP is enabled on the SWA switch, GigabitEthe1/0/1 and GigabitEthe1/0/2 can participate in forwarding
• D.If SWA4 is switched to enable MSTP, one of GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 will be blocked

Which of the following elements may the MAC address table entry of the switch contain?

• A.VLANID
• B.MAC address
• C.Port number
• D.IP address
• E.Aging time

The following statements about BSR and RP in PIMSM are correct:

• A.During C-BSR election, the priority is first compared, and then the IP address of the bootstrap message is compared
• B.BSR is generated through an automatic election process between C-BSR
• C.After receiving the C-RP announcement message, the BSR calculates the RP to be selected by each multicast group according to the relationship between the RP and the multicast group, and multicasts the calculation result
• D.C-RP routers periodically send announcement messages in multicast mode

There are multiple IGMPv2 group member hosts (Client1/Client2/Client3) in the shared network segment, and multiple IGMPv2 routers (Router1/Router2), as shown in the following figure:
192.168.207.254 192.168.207.253
Router1 Router2
+++++
Clientl Client2 Client3
192.168.207.1 192.168.207.2192.168.207.3
So, the following statement is correct

• A.After the host receives the general group query message, after the first host sends the Report message, the other hosts' Report messages are suppressed
• B.Only Router2 periodically sends general group queries to the shared network segment
• C.After the host receives the query message, only Clients send the Report message
• D.Routerl and Router2 periodically send general group queries to the shared network segment
• E.After the host receives the general group query message, Client1, Client2, and Client3 may all send Report messages
• F.Only Router1 periodically sends general group queries to the shared network segment

Regarding the BPDU format of MSTP, the correct statement is

• A.MSTI specifies that the port priority field is 2 bytes in length, including 1 byte of port priority and 1 byte of port number
• B.MSTI specifies that the bridge priority field has a length of 8 bytes, including two bytes of bridge priority and 6 bytes of bridge MAC address
• C.The MSTI calculation process will use the timer value in RSTBPDU instead of carrying the timer parameter in each MSTI configuration message
• D.If the switch is not configured with VLAN to instance mapping, MSTBPDU will not carry any MSTI configuration message
