A. The POE system consists of two parts: PSE equipment and PD equipment, where PD is the power supply device and PSE is the powered device.

B. POE usually uses two power supply methods: mid-span and end-span

C. The voltage provided by the POE power supply is 48V, and the output power usually does not exceed 13W

D. Usually PSE can support mid-span and end-span, while PD can only support one.

A. Netconf protocol is mainly responsible for issuing configurations to SDN network element devices and obtaining device status changes

B. The EVPN protocol obtains ARP and other information through the controller and synchronizes the information across the entire network

C. The Ovsdb protocol is mainly responsible for issuing configurations and forwarding and policy-related entries to SDN virtual switch devices

D. The openFlow protocol is mainly responsible for sending forwarding table entries and policy table entries to the Openflow forwarding device

A. As long as the network topology and unicast routing information remain unchanged, the SPT tree will not change.

B. After the diffusion-pruning process, an SPT is formed between the multicast source and the multicast receiver.

A. Ports configured as edge ports can directly enter the forwarding state without delay

B. The ports that interconnect SWB and SWC can be configured as edge ports to achieve rapid topology convergence

C. If the edge port receives BPDU, it will enter the blocking state

D. Port E0/3 of SWB and SWC can be configured as an edge port

A. It can correct the problem of multicast data packets arriving out of order

B. Best effort delivery, low latency application requirements cannot be guaranteed

C. No congestion control

D. Data packets are received repeatedly

A. Security card

B. Security Management

C. Apply IPSec at network egress

A. No authentication is an optional authentication method

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

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

D. 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.

A. The traffic of VLAN 102 on the SWA switch will be upstreamed through Gigabitethernet 2/0/1

B. The traffic of VLAN 102 on the SWA switch will be transmitted upstream through GigabitEthe 2/0/2

C. The traffic of VLAN 2 on the SWA switch will be transmitted upstream through GigabitEthernet 2/0/1.

D. The traffic of VLAN 2 on the SWA switch will be upstreamed through Gigabitethernet 2/0/2

A. After configuring BPDU protection, the edge end will be closed when receiving BPDU

B. BPDU protection is configured in the protected port view

C. B PDU protection is configured in system view

D. An edge port without BPDU protection configured will become a non-edge port after receiving a BPDU.

A. EVPN can automatically generate routing entries based on virtual machine ARP

B. EVPN VXLAN tunnels are automatically established through type 3 routing

C. EVPN is implemented by extending lSIS

D. EVPN uses 5 types of routing to advertise MAC/IP and other information

A. The calculation of IST only requires the value in the MST exclusive field

B. The number of MSTI configuration messages is determined by the number of VLANs

C. MSTI configuration messages are used for spanning tree calculation in MSTI

D. The MST configuration ID field is used to determine whether the switches belong to the same MST region.

A. When SWB accesses PCA, the message from SWB's GigabitEth1/0/4 does not carry a VLAN Tag

B. PCA's message comes out of SWA's GigabitEthem1/0/3 port and enters SWB's GigabitEthem1/0/4 port. The VLAN tag it carries is VLAN 10.

C. The PCA message enters from the GigabitEthem1/0/1 port of SWA and comes out from the GigabitEthem1/0/3 port with the VLAN Tag VLAN 1

D. SWB's message enters from SWA's GigabitEthem1/0/3 port and leaves from GigabitEthem1/0/1 port with the VLAN tag VLAN10.
