Which layer of the OSI reference model does a switch work at?. Transport layer. Physical layer. Network layer. Data link layer.

Refer to the graphic. A switch attempts to forward a frame to the MAC destination 5489-98ec-f011. What operation will occur on the switch?. The switch will send a request to obtain the MAC address of 5489-98ec-f011. The switch will report that the destination is unreachable and report this to the source. The switch will flood the frame via all ports, with exception of the port on which the frame was received. The switch will drop the frame because it does not have an entry in its MAC address table.

Which of the following description is wrong about the Layer 2 Ethernet switch?. Layer 2 Ethernet switch works at the data link layer. Ability to learn MAC address. It is necessary to make certain modifications to the three-layer header of the forwarded message, and then forward it. Forward according to the Layer 2 header information of the Ethernet frame.

Which of the following descriptions about STP are incorrect?. All the ports of the root switch are designated ports. All the ports of the root switch are root ports. The switch with the smallest priority value is elected as non-root switch. A Layer-2 switching network can have only one designated switch.

What is the total length of the Flags field in the RSTP BPDU message?. 8 bits. 4 bits. 6 bits. 2 bits.

As specified by the RSTP protocol, when a root port fails, which type of port will function as a new root port and enters the forwarding state without any delay?. Edge Port. Alternate Port. Backup Port. Forwarding Port.

Which of the following statements regarding the routing table are correct?. The metrics of different routing protocols are comparable. The routes from generated by different protocols have different preferences. The metrics of different routing protocols are not comparable. The next hop in the routing table is redundant because the outgoing interface can be used for packet forwarding.

Which of the following commands can be used to display the routing table on a Huawei router?. display interface. display current-configuration. display ip path. display ip routing-table.

Which of the following entries is not included in the routing table?. Cost. Source address. Destination address. Next hop.
