Huawei H12-321 Online Questions & Answers

• Question 311:

  In intelligent roaming, for a terminal that supports 802.1v, the AP can assign a target AP to it, requiring it to roam actively without kicking the user off the line.

  A. Correct
  B. False
  A. Correct

• Question 312:

  Radio calibration is implemented as follows: An AP discovers a neighbor, and sends neighbor information to the AC, The AC analyzes the neighbor relationship to obtain the topology between the APs. Then the AC allocates channels to each AP, calculates interference between APs, and adjusts AP channel allocation based on the analysis result to gradually minimize interference between APs.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 313:

  Which of the following statements about N+1 backup is TRUE?

  A. The models and software versions of the active and standby ACs must be the same.
  B. The active and standby ACs can be of different models but must use the same software version.
  C. A standby AC can provide backup services for multiple active ACs. This mode reduces device purchase costs and has higher reliability than VRRP HSB.
  D. N+1 backup is a cold backup mode, which backs up AP and STA information.
  B. The active and standby ACs can be of different models but must use the same software version.

• Question 314:

  On an N+1 backup network, the AP establishes a CAPWAP link with the primary AC. The standby AC sends the primary discovery packets to the local device. The resource consumption of the AP is smaller than that of the dual link.

  A. Correct
  B. False
  A. Correct

• Question 315:

  For a small-scale enterprise, which of the following WIDS/WIPS functions is recommended for WLAN security guarantee?

  A. Rogue device detection
  B. Rogue device countermeasure
  C. WIDS attack detection
  D. Blacklist and whitelist
  D. Blacklist and whitelist

• Question 316:

  Which of the following statements about the three backup modes are TRUE? (Multiple Choice)

  A. Dual-link HSB: backs up AP, STA, and CAPWAP link information.
  B. VRRP HSB: backs up AP, STA, and CAPWAP link information.
  C. No matter in hot standby or cold standby mode, a standby AC can provide backup services for only one active AC.
  D. Dual-link backup is a cold backup mode, which does not back up STA information. An AP sets up a link with both the active and standby ACs. During an active/standby switchover or a revertive switchover, STAs need to go online again and services are temporarily interrupted.
  B. VRRP HSB: backs up AP, STA, and CAPWAP link information.
  D. Dual-link backup is a cold backup mode, which does not back up STA information. An AP sets up a link with both the active and standby ACs. During an active/standby switchover or a revertive switchover, STAs need to go online again and services are temporarily interrupted.

• Question 317:

  The illegal device defense function is to limit the AP or client access by configuring the blacklist function based on the illegal device.

  A. Correct
  B. False
  A. Correct

• Question 318:

  During the roaming process, which packets are handled improperly may cause tunnel aggregation problems?

  A. Unknown unicast
  B. Broadcast
  C. Multicast
  D. Multicast
  B. Broadcast
  C. Multicast

• Question 319:

  Which of the following statements about rogue device countermeasure on a WLAN with the WIDS function enabled are TRUE? (Multiple Choice)

  A. After an AC identifies a rogue AP, it sends rogue AP information to a monitor AP. The monitor AP sends a broadcast Deauthentication frame with the rogue AP's identity information.
  B. After an AC identifies a rogue AP, it sends rogue AP information to a monitor AP. The monitor AP sends a unicast Deauthentication frame with the rogue AP's identity information.
  C. After an AC identifies a rogue STA, it sends rogue STA information to a monitor AP. The monitor AP sends a unicast Deauthentication frame with the rogue STA's BSSID or MAC address.
  D. After an AC identifies a rogue STA, it sends rogue STA information to a monitor AP. The monitor AP sends a broadcast Deauthentication frame with the rogue STA's BSSID or MAC address.
  A. After an AC identifies a rogue AP, it sends rogue AP information to a monitor AP. The monitor AP sends a broadcast Deauthentication frame with the rogue AP's identity information.
  C. After an AC identifies a rogue STA, it sends rogue STA information to a monitor AP. The monitor AP sends a unicast Deauthentication frame with the rogue STA's BSSID or MAC address.

• Question 320:

  Which of the following descriptions is wrong about the AD server and the LDAP server?

  A. AD is a Windows Server-specific directory server
  B. LDAP can be installed on Windows Server
  C. The directory service protocol used by the AD server is the AD protocol.
  D. The directory service protocol used by the AD server is the LDAP protocol.
