A. If multiple backup root bridges are set, when the root bridge fails, the backup root bridge with the smallest MAC address will become the root of the specified MST instance.

B. If not specified, the root bridge of all instances in the MST region is the root bridge of the IST by default.

C. The root primary command can be used to specify the preferred root bridge in a certain instance. After the command is specified, the priority of the root bridge cannot be modified.

D. The root secondary command can be used to specify a backup root bridge in a certain instance.
When the root bridge fails or is shut down, the backup root bridge can replace the root bridge and become the root bridge of the specified spanning tree instance.

A. If no authentication is used, the server will return verification success in any case

B. Password verification is an authentication method that must be supported

C. During the password verification process, the server will check the legitimacy of the user's private key and password. If they are legitimate, the request will be accepted.

D. No authentication is an optional authentication method

A. VLAN 40

B. VLAN 20

C. VLAN 30

D. VLAN 10

A. The routing protocol must select a standard dynamic routing protocol

B. Network equipment is provided by at least three different manufacturers

C. All devices must support the standard topology discovery protocol

D. Each manufacturer's network equipment must be managed using its own network management system

A. You need to enable the local proxy ARP function in the VLAN10 view of SWA so that PCA can communicate with PCB.

B. The local proxy ARP function needs to be enabled in the VLAN20 view of SWB so that PCA can communicate with PCB.

C. The local proxy ARP function needs to be enabled in the VLAN10 virtual interface view of SWA so that PCA can communicate with PCB.
E You need to enable the local proxy ARP function in the VIAN20 virtual interface view of SWB so that PCA can communicate with PCB.

D. PCA can communicate directly with PCB without additional configuration

A. If STP wants to shorten the convergence time, it can only configure a shorter FORWARD Delay time, but this will affect the stability of the network.

B. Compared with STP, STP defines a fast switch mechanism for root ports, which allows Altemate to quickly become the new root port when there is a port failure.

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

D. Compared with STP, RSTP defines a fast switch mechanism for the root port, so that the port connected to the host can quickly enter the forwarding state

A. The data frame with VLAN10 tag is discarded when it enters port Ethernet 1/0/1

B. The data frame with VLAN10 tag will be stripped of the tag when it leaves port Ethernet 1/0/1

C. Data frames with VLAN1 tags will be discarded when they enter port Ethernet 1/0/1

D. The data frame with VLAN10 tag will not be stripped when it leaves port Ethernet 1/0/1.

A. If the Gigabitethernet 2/0/2 port fails, the SWA switch will broadcast flush messages in all VLANs.

B. Under normal circumstances, SWA switch traffic will be upstream through Gigabitethernet 2/0/2

C. Normally, the SWA switch traffic will be upstream through Gigabitethernet 2/0/1

D. If the GigabitEthernet 2/0/1 port fails, the SWA switch will broadcast flush messages in all VLANs.

A. If the link between SWC and SWA is disconnected, SWC will send a TCN BPDU from port E0/3

B. If the link between SWB and SWC is disconnected, both SWB and SWC will send TCN BPDUs from port EO/2.

C. SWD will send TCN BPDU from port E0/1

D. SWB will send TCN BPDU from port E0/2

A. When switches from different manufacturers communicate with each other through MSTP, as long as the domain name, revision level, and VLAN instance mapping are configured exactly the same, the switches can be guaranteed to belong to the same MST region.

B. Since different vendors have different keys, different summary results may be obtained even if the VLAN instance mappings are the same.

C. H3C switches can achieve MSTP interoperability with switches from other manufacturers by configuring summary snooping.

D. When digest snooping is configured, the H3C switch will use the same hash algorithm and key as the peer vendor when performing digest calculations.

A. Host Overlay

B. Multi-tenancy

C. Network Overlay

D. Security Management

A. Alternate ports will neither send configuration BPDUs nor TCN BPDUs.

B. Configuration BPDU is only sent from the designated port, and TCNBPDU is only sent from the root port.

C. Configuration BPDU is usually only sent periodically by the root bridge, while TCNBPDU may be sent by other bridges except the root bridge.

D. Configuration BPDU is usually received only from the root port, and TCNBPDU is received only from the designated port

A. Join

B. Prune

C. Graft

D. Hello

E. Graft-ACK

F. Assert

A. Determine the router end by listening to IGMPQuery messages and IGMP-Snooping

B. By listening to IGMPReport messages, IGMP-Snooping adds ports to known multicast groups or creates new multicast forwarding entries

C. Layer 2 devices rely on IGMP-sliooping to snoop IGMP messages and maintain multicast address forwarding entries at Layer 2

A. Router RTB enables VRRPV3 protocol

B. Router RTB enables VRRPV2 protocol

C. VRRP simple character authentication is enabled on router RTB

D. Router RTB is the owner of the VRRP IP address

A. GetBulkRequest

B. SetRequest

C. GetNextRequest

D. GetRequest

A. Allows dynamic invocation of IT resources through open interfaces to achieve a standard, compatible, secure, intelligent and manageable IT application environment

B. Each module can be planned and deployed separately. Network functions can be added or removed by adding or removing modules, which is conducive to building complex networks.

C. It replaces the traditional hierarchical network model, making it easier to plan and deploy the network.

D. Allow different application functions or application systems to share data, resources and capabilities and participate in business processes
