D. MAC address bypass authentication

Answer: ABC

Question: 2

Which of the following statements about Option 43 in the N+l backup networking are TRUE?

(Multiple Choice)

A. After Option 43 is configured, the AP only unicasts Discovery Request messages to the AC's IP

addresses carried in Option 43.

B. If the AC with the IP address carried in Option 43 does not respond, the AP fails to discover the AC.

C. When configuring Option 43, you need to specify IP addresses of the active and standby ACs for

the AP, and IP addresses of the other active ACs.

D. The command for setting Option 43 on the DHCP server to IP addresses of the active and standby

ACs is option 43 sub-option 2 ip-address ip-address &<l-8>.

Answer: AD

Question: 3

On WLANs where many users exist, such as WLANs in high density scenarios, users compete fiercely

to occupy channels as the number of online users increases. As a result, network quality

deteriorates. To ensure network access experience of online users, Calling Access Control (CAC) can

be configured. CAC allows an AP to control user access based on the CAC thresholds set according to

the radio channel usage, number of online users on a radio, or terminal signal-to-noise ratio (SNR),

ensuring network access quality of online users.

A. TRUE

B. FALSE

Answer: A

Question: 4

Which of the following STAs does MAC address authentication suit the most?

A. Office PC running a Windows OS

B. Testing PC running a Linux system

C. Mobile terminal, such as a smartphone

D. Network printer

Answer: D

Question: 5

On a WLAN with the WIDS function enabled, which of the following devices will NOT trigger rogue

device alarms after they are identified as rogue devices? (Multiple Choice)

A. AP

B. Ad-hoc

C. Wireless bridge

D. STA

Answer: BCD

Question: 6

Engineers of a large enterprise configure the VLAN Pool function when deploying the WLAN. Which

of the following options may be the reasons for configuring the function? (Multiple Choice)

A. There are a large number of IP address requests in some areas.

B. Users request to obtain fixed IP addresses.

C. To reduce the broadcast domain to limit the number of broadcast packets, thereby to improve the

network performance.

D. Break the limit that one SSID can only correspond to one VLAN.

Answer: ACD

Question: 7

On a WLAN that uses the Agile Controller as the admission control server, which of the following is

NOT the cause of 802.lx authentication failures?

A. The key used by the Agile Controller to connect to the device is different from the key configured

on the device.

B. The accounting interval is not configured.

C. Port 1813 is used on the server.

D. The matched authorization rule defines the action "deny".

Answer: B

Question: 8

Which of the following statements about the second Fresnel zone are TRUE? (Multiple Choice)

A. If the RF signal and primary signal have the same frequency and different phases and the two

signals intersect, the RF signal weakens or even offsets the primary signal. Because reflection is one

of the factors causing interference to the primary signal, impact of the second Fresnel zone on signals

must be considered during evaluation of point-to-point communication links.

B. If signals in the second Fresnel zone are reflected to the receive end due to the antenna height and

terrain, the link quality may degrade.

C. Impact of the second Fresnel zone should be considered during network planning and

troubleshooting, especially in flat and dry environments (such as deserts).

D. The second Fresnel zone is surrounded by the first Fresnel zone.

Answer: ABC

Question: 9

When the STA uses the WPA2-802.1x security policy and supports fast roaming, the STA only needs to

perform key negotiation, but does not need to pass 802.lx authentication again during roaming.
