Huawei H12-321 Online Questions & Answers

• Question 1:

  Which routing protocol types are supported by the HWMP protocol?

  A. pro-active
  B. OSPF
  C. on-demand
  D. IGRP
  A. pro-active
  C. on-demand

• Question 2:

  Which of the following statements are TRUE about band steering supported by Huawei devices? (Multiple Choice)

  A. Load balancing between the 2.4 GHz and 5 GHz radios is considered in band steering. An AP determines the radio with which a STA preferentially associates based on numbers of access users on the 2.4 GHz and 5 GHz radios.
  B. Check whether the number of access users on an AP exceeds the start threshold for load balancing between radios. If not, STAs can preferentially associate with the 5 GHz radio.
  C. If the number of access users on an AP exceeds the start threshold for load balancing between radios, the AP determines the frequency band to which the STA connects based on radio load difference computed according to the formula (Number of access users on the 5 GHz radio -Number of access users on the 2.4 GHz radio/Number of access users on the 5 GHz radio x 100%).
  D. After the number of users associated with an AP reaches the start threshold for load balancing between radios, if the value obtained based on the formula (Number of access users on the 5 GHz radio - Number of access users on the 2.4 GHz radio/Number of access users on the 5 GHz radio x 100%) is greater than the gap-threshold value, the AP preferentially associates with the STA on the 5 GHz radio.

• Question 3:

  In the WLAN network using the Agile Controller as the admission controller, the following statement about the pre-authentication domain is correct.

  A. The pre-authentication domain is configured in the same way as the post-authentication domain.
  B. If an ACL is used to match the pre-authentication domain, a user ACL is required.
  C. There are two configuration methods for the pre-authentication domain, one is to call the ACL, and the other is to directly add the exemption rule.
  D. The address that needs to be released before the authentication domain is generally an antivirus gateway, firewall, and mail server.
  B. If an ACL is used to match the pre-authentication domain, a user ACL is required.
  C. There are two configuration methods for the pre-authentication domain, one is to call the ACL, and the other is to directly add the exemption rule.
