• Question 322:

  APs in monitoring mode in a WLAN network can not only monitor peripheral devices but also forward WLAN data.

  A. Correct
  B. False
  B. False

• Question 323:

  In the packet-by-packet power adjustment feature, the AP selects the transmit power for the terminal before sending the data packet. The basis is the current signal strength of the terminal. If the terminal signal is good, it is sent at a lower power. Otherwise, it is sent at a higher power.

  A. Correct
  B. False
  A. Correct

• Question 324:

  In the N+1 backup networking shown in the figure, 300 APs (API to AP300) go online on AC1 and 400 APs (AP301 to AP700) go online on AC2. AC3 is the standby AC and a maximum of 700 online APs can be configured on AC3. However, AC3 allows a maximum of 500 APs to go online concurrently. Which of the following statements are FALSE when the configuration remains unchanged? (Multiple Choice)

  

  A. If AC1 fails, 300 APs (API to AP300) perform an active/standby switchover and go online on AC3.
  B. If AC2 fails, 400 APs (AP301 to AP700) perform an active/standby switchover and go online on AC3.
  C. If AC1 and AC2 fail concurrently, only 500 APs (API to AP500) perform an active/standby switchover and go online on AC3. The rest 200 APs cannot go online on AC3 and services on these APs are interrupted.
  D. After the faulty AC1 or AC2 recovers, APs that perform a revertive switchover and go online on AC1 or AC2 are uncertain.
  C. If AC1 and AC2 fail concurrently, only 500 APs (API to AP500) perform an active/standby switchover and go online on AC3. The rest 200 APs cannot go online on AC3 and services on these APs are interrupted.
  D. After the faulty AC1 or AC2 recovers, APs that perform a revertive switchover and go online on AC1 or AC2 are uncertain.

• Question 325:

  In the WLAN network environment, which categories can be classified according to the device security category?

  A. Legal equipment
  B. Illegal equipment
  C. Testing equipment
  D. Interference equipment
  A. Legal equipment
  B. Illegal equipment
  D. Interference equipment

• Question 326:

  When configuring the connection between the Agile Controller and WLAN, we need to configure a port number if we want to enable Portal, as shown in the following configuration. The default port number is 2000. What is the function of this port number? [AC] web-auth-server listening-port 2000

  A. Destination port number in the packets that the WLAN device sends to the Portal server
  B. Number of the port that WLAN device uses to process Portal protocol packets
  C. Source port number in the packets that the WLAN device sends to the Portal server
  D. Number of the port that the WLAN device uses to receive Portal protocol packets
  B. Number of the port that WLAN device uses to process Portal protocol packets

• Question 327:

  There are three implementations of CAC. What is wrong about the CAC implementation based on channel utilization?

  A. When receiving a new user online request, the AP first calculates the channel utilization rate on the current radio. If the new user threshold is not reached, the new user is allowed to go online.
  B. If the channel utilization reaches the new user threshold after the new user goes online, the access request of other new users is rejected, and an alarm is sent, but the SSID cannot be hidden.
  C. For the access of the roaming user, check whether the channel utilization has reached the roaming user threshold. If it is reached, the roaming user access request is rejected and an alarm is sent.
  D. The AP periodically detects the channel utilization of the radio. Once it falls below the new user threshold, it sends a release alarm to allow new users to go online.
  B. If the channel utilization reaches the new user threshold after the new user goes online, the access request of other new users is rejected, and an alarm is sent, but the SSID cannot be hidden.

• Question 328:

  If a small AP that can accommodate up to 90 people is deployed with 3 APs, the CAC can be configured on each AP to limit the number of users to 30. If the SSID is hidden, the load balancing between APs can be implemented indirectly.

  A. Correct
  B. False
  A. Correct

• Question 329:

  Which of the following statements about backup CAPWAP tunnel setup are TRUE? (Multiple Choice)

  A. The AP and ACs set up the primary and backup tunnels at the same time and complete configuration delivery.
  B. The AP sends a Discovery Request message to the standby AC in broadcast mode.
  C. The AP sends a Join Request message, notifying the standby AC that the configurations have been delivered.
  D. After receiving the Join Request message, the AC sets up a CAPWAP tunnel with the AP but does not deliver configurations to the AP.
  C. The AP sends a Join Request message, notifying the standby AC that the configurations have been delivered.
  D. After receiving the Join Request message, the AC sets up a CAPWAP tunnel with the AP but does not deliver configurations to the AP.

• Question 330:

  In the WLAN network with WIDS enabled, what is the correct statement about the illegal device counter-function?

  A. When the AC determines that the device is a rogue AP, it notifies the monitoring AP of the rogue AP. The monitoring AP sends a broadcast deauthentication frame as an illegal AP.
  B. When the AC determines that the device is a rogue AP, it notifies the monitoring AP of the rogue AP. The monitoring AP sends a unicast deauthentication frame as an illegal AP.
  C. When the AC determines that the device is an illegal user terminal, the monitoring AP uses the BSSID or MAC address of the illegal device to send a unicast deauthentication frame.
  D. When the AC determines that the device is an illegal user terminal, the monitoring AP uses the BSSID or MAC address of the illegal device to send a broadcast deauthentication frame.
  A. When the AC determines that the device is a rogue AP, it notifies the monitoring AP of the rogue AP. The monitoring AP sends a broadcast deauthentication frame as an illegal AP.
  C. When the AC determines that the device is an illegal user terminal, the monitoring AP uses the BSSID or MAC address of the illegal device to send a unicast deauthentication frame.
