A. Among the many actions defined by OpenFlow, drop means to discard directly

B. Feature Request message is used to negotiate the OpenFlow version

C. OpenFlow channels can be encrypted using TLS

D. Hello message is used for OpenFlow keepalive

A. After the loop protection function is enabled, when the BPDU stored on the port ages, the loop protection takes effect.

B. If the role of the root port changes, it will change to the Discarding state and will not forward messages, so as not to form a loop in the network. The Discarding state will be maintained until the port receives a BPDU again and becomes a root port again.

C. In MSTP, this function is valid for root ports, alternate ports, and backup ports.

D. Link blocking or one-way link may cause loops

A. Before deleting the primary IP address of the VLAN interface, you must first delete the secondary IP address.

B. Only when two or more VLAN interfaces are configured with IP addresses, the switch will have the Layer 3 routing forwarding function.

C. As long as an IP address is configured for a VLAN interface, the switch will have Layer 3 routing and forwarding capabilities.

D. When configuring a primary IP address for a VLAN interface, if the interface already has a primary IP address, the original primary IP address must be deleted before configuring a new primary IP address.

A. If there are multiple alternate ports on SWD, when the root port is DOWN, SWD will select the port with the highest priority from these alternate ports as the new root port

B. If the SWD port EO/1 goes down, the SWD port EO/2 will immediately change from an alternate port to a new root port.

C. If the spanning tree operation mode of SWB and SWC is changed to STP, the Alternate port of SWD can still directly enter the forwarding state after becoming the new root port.

D. After the topology converges, SWD will have one port as an alternate port

A. Data frames with VLAN 20 tags will be discarded when they enter port Ethernet 1/0/2

B. The data frame with VLAN1 tag will not be stripped when it leaves port Ethernet1/0/2

C. The current switch has only VLAN1 and VLAN10.

D. Port Ethernet1/0/2 only allows data from VLAN 1 and VLAN 10 to pass through.

A. 232.255.255.255

B. 224.0.0.13

C. 239.255.255.255

D. 242.255.255.250

A. RT2

B. RT1

C. RT3

A. Traffic between firewalls and load balancers is directly interconnected through the secure intranet without going through a gateway

B. Hardware firewall mounted on the gateway

C. Security devices and gateways communicate with each other through VXLAN

D. Hardware load balancing is mounted on the gateway

A. MAC20

B. 0000.0000.0000

C. MAC10

D. MAC_A

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. True

B. False

A. If the user authentication is successful, the port will leave the Guest VLAN

B. If the user fails authentication, he can only access the resources in the VLAN that the user initially configured.

C. If the user authentication is successful, the user may return to the initially configured VLAN

D. If the user fails authentication, he can only access resources in the Guest VLAN

A. VLAN3

B. VLAN 1

C. VLAN 10

D. VLAN2

A. IGMPV2 and IGMPV3 have specific group query messages

B. The election principles of the three version queryers are the same

C. IGMPV2 and IGMPV3 designed a member reporting suppression mechanism

D. Only IGMPV3 has a specific group joining mechanism

E. IGMPv1 does not have leave messages

A. Southbound interfaces such as OpenFlow and Netconf

B. RestFul API and other northbound interfaces

C. VXLAN

D. Strong control and weak control

A. TO_IN (A, G)

B. TO_IN (Null, G)

C. TO_EX (Null, G)

D. TO_EX (A, G)

A. Configure the PIM protocol

B. Enter IGMP view

C. SB sets the IGMP protocol version

D. Enable multicast globally using the multicast routing-enable command
