Question 56

The following statements about the STP protocol are correct

A.All VLANs in the STP network share a spanning tree, and load sharing of different VLANs on Trunk links cannot be realized.

B.If there are a large number of hosts in the STP network, frequent online and offline of the hosts will generate a large number of TCN BPDUs

C.The port in STP must pass two ForwardDelays from Blocking to Forwarding before data can be sent.

D.When the topology changes frequently, some ports are often in Blocking state, which may cause long-term network interruption

Question 57

As the above topology, the loop formed by SWA, SWB and SWC enables STP, then the following statement is correct:

A.Before joining SWD, after STP converges, SWC will receive configuration BPDUs from both E0/1 and E0/2

B.After the STP converges, connect the SWD to the network through the dotted link 1 in the figure, and the SWD will first send the configuration BPDU with itself as the root, and the SWB will immediately respond to the configuration BPDU with the SWA as the root.

C.Before joining SWD, after STP convergence, SWB port E0/2 is an alternate port

D.After the STP converges, connect the SWD to the network through the dotted link 1 in the figure, then the SWD will first send the configuration BPDU with itself as the root, and after the longest Hello Time, the SWC will send the SWD the configuration with the SWA as the root BPDU

Question 58

Before configuring Layer 3 multicast, the first configuration that needs to be done is

A.Configure PIM protocol

B.SB sets the IGMpi protocol version

C.Enter IGMP view

D.Enable multicast globally through the multicastrouting-enable command

Question 59

When the switch running MSTP and the switch running RSTP work together, the statement is correct.

A.MSTP switch and RSTP switch can belong to the same MST domain

B.MSTP switch will parse RSTBPDU into MST BPDU, where IRPC is 0

C.The RSTP switch regards the MST domain as a logical switch, and the bridge ID is the ID of the switch directly connected to the RSTP switch in the MST domain

D.The MSTP switch will treat the RSTP switch as an MSTP domain composed of a single switch

Question 60

To configure the Ethernet1/0/1 port of the switch SWA as a hybrid port, its PVID is VLAN20, and when sending VLAN20 data frames without tagging, when sending VLAN 10 data frames, then the following configuration Is the process correct (choose one or more)

A.[SWA]vlan10 [SWA-vlan 10]quit [SWA]vlan 20 [SWA-vlan20]quit [SWA]interface Ethernet 1/0/1 [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]vlan10 [SWA-vlan10]quit [SWA]vlan 20 [SWA-vlan20]quit [SWA]interface Ethernet 1/0/1 [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 [SWA-Ethernet1 /0/1 ]port hybrid vlan 20 untagged

C.[SWA]vlan10 [SWA-vlan 10]quit [SWA]vlan 20 [SWA-vlan20]port Ethernet 1/0/1 [SWA-vlan20]quit [SWA]interface Ethernet 1/0/1 [SWA-Ethernet1 /0/1 ]port link-type hybrid [SWA-Ethernet1 /0/1]port hybridvlan 10 tagged

D.None of the above is correct

E.[SWA]interfaceEthernet 1/0/1 [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 [SWA-Ethernet1/0/1]port hybrid vlan 20 untagged [SWA-Ethernet1/0/1]quit [SWA]vlan 10 [SWA-vlan10]quit[SWA]vlan 20
