Then, when the receiver (Receiver) sends a group join request, which of the following routers have (*, G) entries

B.RT2

C.RT1

GB0-371-ENU Exam Question 47

Regarding the bridge ID of STP, which statement is correct?

A.Bridge ID is composed of bridge MAC address and priority field. When comparing bridge ID, compare the MAC address first. The smaller MAC address value is preferred.

B.The bridge with the smallest bridge ID in the network will eventually become the root bridge after STP calculation

C.The length of the bridge priority field is 2 bytes, so the value range of the bridge priority is 0-65535

D.The MAC addresses of SWA and SWB are 00-E0-FC-00-00-11 and 00-E0-FC-11-00-11, and the priority of the two are 32768 and 4096 respectively. When SWA and SWB are used After ring networking and spanning tree protocol is enabled, SWA will become the root bridge

GB0-371-ENU Exam Question 48

The topology is shown in the figure, and the STP calculation is performed. The correct result is

A.SWD port E0/2 is the root port

B.SWA is the root bridge in the network

C.SWB port E0/2 is the designated port

D.SWC will forward configuration BPDUs from port E0/3 to SWD

GB0-371-ENU Exam Question 49

Which statement is correct about the communication between switch VLANs?

A.The hosts in the VLAN divided by the switch can communicate, but the hosts in the VLAN cannot communicate

B.After the two-layer switch divides VLANs, hosts in different VLANs can use routers to realize communication. The method is that there is a physical interface and a physical connection between the router and each VLAN.

C.After the two-layer switch divides VLANs, hosts in different VLANs can communicate with the router by using an interface to connect the trunk port of the switch, and the router must support the 802.1Q protocol

D.After the three-layer switch divides VLANs, hosts in different VLANs can communicate. The method is that the three-layer switch creates a virtual three-layer VLAN interface for each VLAN, and the VLAN interface needs to be configured with the corresponding IP address

GB0-371-ENU Exam Question 50

Regarding the configuration of BPDU and TCNBPDU, the statements are correct.

A.Configuration BPDUs are usually only sent periodically by the root bridge, and TCNBPDUs may be sent by other bridges except the root bridge.

B.The configuration BPDU is usually received only from the root port, and the TCNBPDU is only received from the designated port

C.Configure BPDUs to be sent only from the designated port, and TCNBPDUs to be sent only from the root port

D.AIternate port will neither send configuration BPDU nor TCNBPDU
