Question 76

As shown in the network, the switches all run RSTP. Initially, SWA, SWB and SWC are interconnected through links 1, 2, and 3. When the following changes occur in the network connection, the correct statement is:

A.When the link between SWB and SWC is down, both SWB and SWC will send RST BPDU with TC set

B.As shown in the figure, when SWB is connected to another switch SWD running RSTP, SWB will send RSTBPDU with TC set

C.When SWC edge port E0/1 is connected to a PC, SWC will send RST BPDU with TC set

D.As shown in the figure, when SWB is connected to another switch running RSTP, SWD will send RSTBPDU with TC set.

Question 77

In the network connection shown in the figure, SWA and SWB are Layer 3 switches, running STP+VRRP, and after the initial configuration is completed, SWA is the root of STP and Master of VRRP, and SWC is the Layer 2 switch connected to the access terminal , The following description about network link failure is correct

A.When the link between SWA and SWB is interrupted, the VRRP Master will switch, and SWB will become the new VRRP Master

B.After the link between SWA and SWC is interrupted, the VRRP Master will remain unchanged, but the SWC downstream terminal will not communicate with the gateway.

C.When the link between SWA and SWC is interrupted, the topology of STP will change, and G1/0/2 of SWC will become Forwarding

D.When the link between SWA and SWB is interrupted, the topology of STP will change, and both upstream ports of SWC will become Forwarding

Question 78

The Ethemet1/0/1 port configuration of the switch SWA is as follows:
interface Ethernet 1/0/1
port link-type trunk
port trunk permit vlan 10
port trunk pvid vlan 20
Now you need to modify the Ethernet 1/0/1 port of the switch SWA to a Hybrid port, the PVID is VLAN20, and the data frame of VLAN10 is tagged, then the following configuration process is correct (choose one or more)

A.[SWA-Ethernet1/0/1]undoportlink-type [SWA-Ethernet1 /0/1 ]portlink-type hybrid [SWA-Ethernet1/0/1]port hybrid pvid vlan 20 [SWA-Ethernet1/0/1]port hybrid vlan 10 tagged

B.[SWA-Ethernet1/0/1]portlink-type access [SWA-Ethernet1/0/1]port access vlan 20 [SWA-Ethernet1/0/1]port link-type hybrid [SWA-Ethernet1/0/1]port hybrid vlan 10 tagged

C.[SWA-Ethernet1/0/1]portlink-type access [SWA-Ethernet1/0/1]port link-type hybrid [SWA-Ethernet1/0/1]port hybrid pvid vlan 20 [SWA-Ethernet1/0/1]port hybrid vlan 10 tagged

D.[SWA-Ethernet1/0/1]port link-type hybrid

E.None of the above is correct

Question 79

As shown in the network topology, if STP is enabled on SWA and SWD, the statement about SWA and SWD port status changes is correct.

A.If i sets the bridge priority of SWD to 0, the role of SWA port E0/1 will be changed from a designated port to a root port, and the port will remain in the Forwarding state during the transition.

B.If the SWD bridge priority is set to 0, the SWD ports E0/1 and E0/2 will enter the Forwarding state after going through the Listening state and the Learning state

C.SWD port EO/1 will change from designated port to root port in the Listening state

D.If the cost value of the SWD port EO/2 link is changed to 100, the port E0/2 will immediately turn into the new root port and enter the Forwarding state

Question 80

The Ethernets port configuration of the switch SWA is as follows:
interface Ethernet 1/0/1
port link-type trunk
port trunk permit vlan 10
port trunk pvid vlan 20
Now you need to modify the Ethernet1/0/1 port of the switch SWA to a Hybrid port, PVID is VLAN20, and the data frame of VLAN20 is not tagged, and the data frame of VLAN 10 is tagged, Then the following configuration process is correct (choose one or more)

A.[SWA-Ethernet1/0/1]portlink-type access [SWA-Ethernet1/0/1]port link-type hybrid [SWA-Ethernet1/0/1]port hybrid pvid vlan 20 [SWA-Ethernet1/0/1]port hybrid vlan 10 tagged

B.[SWA-Ethernet1/0/1]undoportlink-type [SWA-Ethernet1 /0/1 ]portlink-type hybrid[SWA-Ethernet1/0/1]port hybrid pvid vlan 20 [SWA-Ethernet1/0/1]port hybrid vlan 10 tagged

C.[SWA-Ethernet1/0/1]port link-type access [SWA-Ethernet1/0/1]port access vlan 20 [SWA-Ethernet1/0/1]port link-type hybrid [SWA-Ethernet1/0/1]port hybrid vlan 10 tagged

D.None of the above is correct

E.[SWA-Ethernet1/0/1]port link-type hybrid
