A. Layered Troubleshooting

B. Blocking Troubleshooting

C. substitution method

A. AP and AC routes are unreachable | The license on the AC is not enough

B. AP is not powered on

C. The radio port configuration on the AC is incorrect

D. The serial number of the AP template on the AC is incorrectly configured

E. The AP cannot get an IP address because the DHCP address pool is full

A. 802.1X authentication occurs after the association is completed, and the authentication and encryption trust interaction with the AP is completed through eapol

B. 802.1X authentication occurs during the authentication process, and the association process starts after the authentication is completed. The question bank is required for the association process.

C. PSK authentication occurs during the authentication process, and the association process starts after the authentication is completed

D. PSK authentication occurs after the association is completed, and the authentication and encryption information exchange with the AP is completed through eapol

A. AP hardware problem

B. The version on the AC does not match the version on the AP

C. There is no version of this AP on the AC

D. There is not enough space on the AP to store the version

A. arp-snooping enable

B. user-isolation enable

C. DHCP-snooping enable

D. port-security enable

A. The wireless user switches from SSID A to SSID B, which is a roaming behavior.

B. Wireless users can roam across ACs

C. When the wireless user travels, the IP address of the client changes, and the VLAN changes.

D. When the wireless user roams, the IP address of the client remains unchanged, and the VLAN remains unchanged.

A. Female

B. male

A. Fat AP and Thin AP can bridge each other

B. Fat AP and Fat AP can bridge each other

C. Bridging links can be cascaded, but since each level of bridging will bring about 50% link bandwidth loss and increase delay, it is not recommended to use multi-level bridging cascades

D. Thin AP and Thin AP cannot bridge each other

E. Generally used with high-gain directional antennas for long-distance bridging, and ensure that the Fresnel area between the AP connections at both ends of the bridge is not blocked by obstacles

A. Cassette devices are directly connected for stacking

B. stacking devices in the same frame

C. Boxed devices are stacked across devices

D. Cross-frame device stacking

A. 802.11g devices are compatible with 802.11b devices

B. The modulation mode of 802.11g 54Mbps is the same as that of 802.11a 54Mbps, both of which use OFDM technology

C. 802.11g devices are compatible with 802.11a devices

D. 802.11g provides the same maximum speed as 802.11b

A. The interference from FM radio is narrowband.

B. The signal of each frequency point in the spectrum analyzer should be a standard sine wave if viewed through an oscilloscope.

C. There are two common methods for signal analysis: time domain analysis and frequency domain analysis. Time domain analysis is usually viewed with an oscilloscope, while frequency domain analysis is usually viewed with a spectrum analyzer.

D. In theory, white noise affects all frequencies of a radio signal uniformly, while narrowband interference is noise only within a small range of frequencies.

A. The AP installation location must meet the engineering design requirements. If the AP installation location needs to be changed, the approval of the design unit and the construction unit must be obtained, and the change procedures must be handled.

B. The outdoor construction site should be easy to fix the device without obstruction; the building wall involved in the outdoor hardware installation should be firm and complete.

C. If the AP is placed in a waterproof box, the box must be firmly fixed and kept vertical: the box should be ventilated to facilitate the heat dissipation of the equipment: the box can be installed on the inner façade of the roof wall to block light In order to keep out the rain, all cables entering the waterproof box need to be waterproofed or routed downwards; the waterproof box can also be fixed on the pole used to install the antenna with a hoop.

D. Lightning protection and waterproofing must be done for outdoor equipment installation: Additional lightning protection devices are required for outdoor construction, such as lightning rods, ground stakes, grounding bars, etc. The AP surface should be perpendicular to the horizontal plane, and the outlet holes for wiring should be waterproofed Strict waterproof sealing measures should be taken at each joint.

A. High roaming requirements

B. High requirements for signal strength and coverage

C. There is a hidden danger of mutual interference between different signal systems

D. low user density

A. <H3C>ap-model fit

B. <H3C>ap-mode fit

C. [H3C] ap-model fit

D. [H3C] ap-mode fit
