In NTP client/server mode, which of the following statements about configuration verification are correct? (Multiple choice)

• A.The client should associate the key with the server to successfully complete the verification.
• B.If the client does not enable authentication and the server enables authentication, the client's clock can also be synchronized
• C.When enabling authentication, you must configure both the authentication key and the trusted key.
  Otherwise, authentication cannot be started normally.
• D.The authentication of the client and server must be consistent, otherwise the clock synchronization will fail.

As shown in the figure, there is no connection between SWA and SWB at the beginning. SWA and SWB enable RSTP. When the topology is stable, the ports connecting SWA and SWB assume that SWA will become the new root bridge. Which of the following statements are correct? (Multiple choice)

• A.During the P/A process, no timer will be used, so the designated port can quickly enter the forwarding state, thereby achieving rapid network convergence.
• B.After SWB completes the synchronization process, it will reply with an Agreement message to SWA, and its port E1/0/1 will immediately enter the forwarding state.
• C.After receiving the Agreement message sent by SWB, SWA's port E1/0/1 will immediately enter the forwarding state.
• D.The designated port of SWB will continue the P/A handshake process with the downstream switch

The IP address of host PCA is 40.1.1.1, and the MAC address is 0011.1111.1111. It is connected to the GigabitEthernet1/0/1 port of switch SWA. The following commands are configured on switch SWA:
[SWA] vlan 10
[SWA-vlan10] quit
[SWA] vlan 20
[SWA-vlan20] protocol-vlan ipv4
[SWA-vlan20] quit
[SWA] vlan 30 [SWA-vlan30] quit
[SWA] mac-vlan mac-address 0011-1111-1111 vlan 30
[SWA] vlan 40
[SWA-vlan40] ip-subnet-vlan ip 50.1.1.0 255.255.255.0
[SWA-vlan40] quit
[SWA] interface GigabitEthernet 1/0/1
[SWA-GigabitEthernet1/0/1] port link-type hybrid
[SWA-GigabitEthernet1/0/1] port hybrid pvid vlan 10
[SWA-GigabitEthernet1/0/1] port hybrid vlan 10 20 30 40 untagged
[SWA-GigabitEthernet1/0/1] port hybrid protocol-vlan vlan 20 0
[SWA-GigabitEthernet1/0/1] port hybrid ip-subnet-vlan vlan 40
[SWA-GigabitEthernet1/0/1] mac-vlan enable
[SWA-GigabitEthernet1/0/1] vlan precedence ip-subnet-vlan
After the configuration is complete, can you tell which one the PCA will join?

• A.VLAN 20
• B.VLAN 30
• C.VLAN 10
• D.VLAN 40

As the basis for the implementation of the SNMP protocol, the managed objects in the MIB can be identified by object name or OID. Which of the following descriptions of the managed objects are correct? (Multiple choice)

• A.The managed object exists in the form of a node, which can be represented by either object name or OID, and the two are mapped one to one.
• B.Scalar nodes only have read attributes, not write attributes
• C.Leaf nodes are divided into table nodes and scalar nodes. When the network management workstation accesses a leaf node, it must add the instance ID after the corresponding OID of the leaf node.
• D.The nodes in MIB are divided into leaf nodes and non-leaf nodes. Non-leaf nodes cannot be accessed.

In PIM-DM networking, which of the following is correct about the router sending the Prune message? (Multiple choice)

• A.After the router RPF interface receives the Prune message, it will no longer receive messages from the corresponding multicast group on this interface.
• B.After the router interface receives the Prune message, it will no longer send messages of the corresponding multicast group on this interface.
• C.When the router has no local directly connected multicast receiver, it sends a Prune message to the upstream RPF neighbor.
• D.When the outbound interface list in the router (S, G) table entry is empty, a Prune message is sent to the upstream RPF neighbor.
• E.The party that fails the Assert will send a Prune to the winning party
