The 802.11b protocol defines 14 channels in the 2.4GHz frequency band, and there is overlap in the frequency spectrum between adjacent channels.
In order to maximize the use of frequency band resources, which set of channels can be used for wireless coverage?

The MAC address table on a layer 2 switch is shown in the figure.

When the switch receives a frame with a destination MAC address of 00-13-72-8E-4B-C1 from the E1/0/2 interface, the switch will ______ the frame.

As shown in the figure, S3610 switch SWA uses ports E1/0/1 and E1/0/2 to connect to another switch SWB. In order to increase bandwidth, static link aggregation needs to be configured on the switch.
Which of the following configuration is correct? (multiple choice)

The customer router connects to the operator's network through the S1/0 interface. The S1/0 interface uses the default configuration.
The following route is configured on the router: [MSR]ip route-static 0.0.0.0 0.0.0.0 Serial1/0
However, when viewing the routing table through display ip routing-table, it is found that the route is not displayed in the routing table. Based on this, it is speculated that the possible reason is ______. (Multiple choice)

A company purchased switches from two manufacturers, A and B, for network engineering implementation. Need to use link aggregation technology between the switches of the two vendors. After consulting the relevant documents, it is found that the switch of manufacturer A does not support the LACP protocol.
