Huawei HCIP-WLAN CEWA(Huawei Certified ICT Professional-Wireless Local Area Network-Constructing Enterprise WLAN Architecture) Sample Questions:

1. Which statements about reliability measurement are TRUE? (Multiple Choice)

A) The formula for calculating the MTTR is as follows: MTTR= Fault detection time + Hardware replacement time + System initialization time + Link recovery time + Route convergence time + Forwarding recovery time A smaller MTTR indicates a higher reliability.
B) MTTR refers to the average time from the fault occurrence time to the fault recovery time.
C) Generally, system reliability is determined by mean time between failure (MTBF) and mean time to repair (MTTR).
D) MTBF refers to the average time (usually expressed in hours) from the fault occurrence time to the fault recovery time. A larger MTBF indicates a higher reliability.

2. Which of the following measures can be taken to make STAs preferentially associate with the 5 GHz radio? (Multiple Choice)

A) Configure an AP to preferentially respond to Probe Request packets on the 5 GHz radio sent by STAs, and respond for several times before responding Probe Request packets on the 2.4 GHz radio.
B) Configure a higher Beacon frame rate, a longer interval for sending Beacon frames, and a smaller number of retransmissions of Probe packets on the 5 GHz radio than on the 2.4 GHz radio.
C) Configure the transmit power on the 5 GH radio 3 dB to 8 dB higher than that on the 2.4 GHz radio.
D) Configure an AP to reject the request from a STA to associate with the 2.4 GHz radio of an AP, and allow STA association only after the number of rejections reaches the threshold. Configure an AP to immediately allow STA association if a STA requests to associate with the 5 GHz radio.

3. On a WLAN, which of the following attack detection functions require support of the dynamic blacklist function? (Multiple Choice)

A) Spoofing attack detection
B) Brute force attack detection
C) Weak IV attack detection
D) Flooding attack detection

4. 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) STA
B) Ad-hoc
C) AP
D) Wireless bridge

5. Which of the following statements is TRUE about the address of the AC that an AP accesses in VRRP HSB mode?

A) The AP accesses any address configured on the AC.
B) The AP accesses the physical address of the active AC.
C) The AP accesses the virtual address of the active or standby AC.
D) The AP accesses the physical address of the standby AC.
