A. The destination IP address of the member Leave message is the same as the group address in the message

B. The destination IP address of the specific group query message is the same as the group address in the message

C. The destination IP address of the general group query message is 224.0.0.1, and the group address field in the message is 0.0.0.0

D. The destination IP address of the member report message is the same as the group address in the message

A. Service Layer

B. Network layer

C. Business Layer

D. Application layer

A. The MSTP BPDU consists of the RSTBPDU field and the MST-specific field.

B. If the MST region is regarded as a switch running RSTP logically, the CIST region root ID is equivalent to the designated bridge ID of the RSTP switch. Usually, this ID is the smallest bridge ID in the MST region.

C. If the MST region is regarded as a switch running RSTP logically, the CIST external path cost is equivalent to the root path cost of the RSTP switch.

D. To calculate CST, only the value of the RSTBPDU field is required

A. The Alternate port and Backup port on the CST must be the region boundary port and must not be in the MST region.

B. The calculation process of MSTP is to first calculate CST and IST through MSTBPDU, and then the switches in the domain send MSTIBPDU to calculate the spanning tree of each instance.

C. When calculating CST, external path costs are given priority, and internal path costs are compared only when external path costs are the same.

D. In MSTP, since the ports at both ends of the link may be designated ports in different instances, the ports at both ends of the link may both receive and send MST BPDUs at the same time.

A. A spanning tree instance in MSTP can contain multiple VLANs

B. The basic idea of MSTP is to calculate a spanning tree for each VLAN, and each tree corresponds to a spanning tree instance.

C. In MSTP, a VLAN can be mapped to multiple spanning tree instances as needed.

D. MSTP is defined in 802.1s. It can meet the requirements of fast convergence and load sharing.

A. Compared with STP, STP defines a fast switch mechanism for designated ports, which allows the designated port to quickly enter the forwarding state without waiting for twice the Forward Delay time.

B. Compared with STP, STP defines a fast root port switching mechanism, which allows the Alternate to quickly become the new root port.

C. If STP wants to shorten the convergence time, it can only configure a smaller ForwardDelay time, but this may affect the stability of the network.

D. Compared with STP, RSTP defines edge ports, which can make the ports connected to the i machine quickly enter the forwarding state

A. SOA solutions require the integration of IT infrastructure and the construction of a unified IT infrastructure platform based on network technology.

B. ITolP solution embodies the core idea of SOA

C. SOA is based on the network, eliminates the information gap caused by heterogeneous systems, integrates storage, security, multimedia and other services, and realizes the componentization and resourceization of IT infrastructure.

D. ITolP allows for flexible, rapid, and efficient construction of enterprise intelligent applications, and can quickly adapt to changes in enterprise business processes

A. After SWA receives the BPDU with TC set, it will clear all MAC address tables and send the RST BPDU with TC set from E0/2.

B. After receiving the BPDU with TC set, SWC will clear the MAC address learned on port E0/1 and send a RST BPDU with TC set from the port.

C. SWB will send a RST BPDU with TC set within twice the Hello Time.

D. SWB will clear the MAC addresses learned on ports E0/1 and E0/2 and send RST BPDUs with TC set from these two ports.

A. If sub-ring 2 and sub-ring 3 are added to the same ring group, the edge nodes and auxiliary edge nodes of sub-ring 2 and sub-ring 3 in the ring group can be different

B. It is not possible to add sub-ring 2 and sub-ring 3 to the same ring group.

C. If sub-ring 2 and sub-ring 3 are added to the same ring group, the ring groups should be configured on the switches SWB, SWC, SWE, and SWF respectively and the configurations should be consistent.

D. If sub-ring 2 and sub-ring 3 are added to the same ring group, the primary ring links corresponding to the edge nodes and auxiliary edge nodes of sub-ring 2 and sub-ring 3 in the ring group should be consistent.

A. Isolate-user-vlan technology

B. Port isolation technology

C. Using the port hybrid attribute

D. Super VLAN technology

A. oVSDB

B. VXLAN

C. OpenFlow

D. NVGRE

A. When SWB's port E0/2 goes down, SWD's port E0/2 becomes the new root port and immediately enters the forwarding state

B. Since SWB and SWC do not enable the spanning tree protocol, when the root port of SWD goes down, the alternate port cannot immediately become the new root port and enter the forwarding state.

C. When SWB's port EO/2 is DOWN, SWD's port EO/2 will wait for 3 Hello Times before becoming the new root port and entering the forwarding state.

D. SWD will have a port with the role of Alternate
