Demo Questions

Question 1
To which of the following scenarios is radio calibration applicable? (Choose all that apply.)
  1. Enterprise office scenario
  2. Rail transportation scenario
  3. High-density scenario
  4. WDS or mesh backhaul scenario
Correct answer: A, B, C
Question 2
In a dual-link HSB scenario, after an AP sets up a CAPWAP links with the active and standby WACs, which of the following types of packets does the AP periodically send to the WACs to detect link status?
  1. DTLS
  2. Join
  3. Echo
  4. Keepalive
Correct answer: C
Question 3
In a dual-link backup scenario, the active/standby link switchover mode is set to priority. When the active link recovers, the AP detects that the original active link has a higher priority and triggers a switchback. How many Echo intervals does the AP wait for before switching back to the original primary WAC?
  1. 20
  2. 10
  3. 15
  4. 5
Correct answer: B
Question 4
Which of the following statements about EAP relay and EAP termination are false? (Choose all that apply.)
  1. In EAP termination mode, an access device encapsulates EAP packets sent by an 802.1X client into RADIUS packets, without processing the data in the EAP packets.
  2. In EAP relay mode, an access device extracts information from EAP packets, encapsulates the information into RADIUS packets, and sends the RADIUS packets to an authentication server.
  3. In EAP termination mode, an access device extracts client authentication information from the EAP packets sent by a client and encapsulates the information using the standard RADIUS protocol. The access device supports only the EAP MD5-Challenge authentication method.
  4. The EAP termination mode simplifies the processing on an access device and supports various authentication methods. However, this mode requires an authentication server to support EAP and have high processing capability.
Correct answer: A, B
Question 5
Which of the following encapsulation formats are used for EAP termination in 802.1X authentication?
  1. EAP-TLS
  2. EAPoL
  3. EAPoR
  4. EAP
Correct answer: C
Question 6
The display sync-configuration compare command is executed on the backup WAC in HSB to check wireless configuration synchronization. Based on the command output, which of the following statements are true? (Choose all that apply.)

  2. The home agent communicates with the gateway on the STAs’ home network at Layer 3
  3. A home AP can function as a home agent of STAs.
  4. A home WAC can function as a home agent of STAs.
Correct answer: B, D
Question 9
Which of the following statements about fingerprint-based positioning technology are true?
  1. The positioning engine generates a virtual fingerprint library through calculations based on the AP deployment and environment information.
  2. Terminals learn from each other to form a fingerprint library that can be shared.
  3. APs collect surrounding environment information to form a fingerprint library.
  4. The fingerprint map is obtained through onsite information collection.
Correct answer: D
Question 10
Which of the following statements are true about data collection of iMaster NCE-CampusInsight?
  1. iMaster NCE-CampusInsight uses telemetry to implement efficient data collection.
  2. Calculated data can be displayed on iMaster NCE-CampusInsight only after a license is loaded on the device management page.
  3. To collect data from WLAN devices, ensure that WACs can communicate with the southbound IP address of iMaster NCE-CampusInsight. APs do not need to communicate with the southbound IP address of iMaster NCE-CampusInsight.
  4. The UTC time of iMaster NCE-CampusInsight must be the same as that of its managed devices.
Correct answer: A, C
Question 11
Which of the following configuration may cause STAs to experience a slow Internet connection?
  1. QoS CAR is configured in the traffic profile
  2. Radio 1 of APs is disabled
  3. TKIP encryption is configured, causing a low link setup rate
