Huawei HCIP-WLAN CEWA(Huawei Certified ICT Professional-Wireless Local Area Network-Constructing Enterprise WLAN Architecture) Sample Questions:
The AP periodically sends Discovery Request messages to check whether the original primary tunnel recovers. If the original primary tunnel recovers, the AP switches STA data back to this tunnel after a delay because this tunnel has a higher priority than the other one.
To prevent frequent switchovers caused by network flapping, the AP requests ACs to perform revertive switchover after six Echo intervals, and then sends STA data to the new active AC.
- A. FALSE
- B. TRUE
Correct Answer: A 🗳️
Which statements about Mesh radio are TRUE? (Multiple Choice)
- A. The distance settings between neighboring Mesh nodes must be the same.
- B. The 2.4 GHz frequency is recommended for Mesh.
- C. Short GI is recommended regardless of the distance to improve bandwidth on air interfaces.
- D. The power settings on neighboring Mesh nodes must be the same to ensure equivalent bidirectional bandwidth.
Correct Answer: A,D 🗳️
To remain the existing wired network architecture, an enterprise deploys the AC in bypass mode. Considering the large data traffic on the WLAN and needs for AC capacity expansion in the future, it is recommended that the tunnel forwarding mode be used to transmit WLAN services.
- A. FALSE
- B. TRUE
Correct Answer: A 🗳️
In which authentication mode can user information synchronized by the Agile Controller be used? (Multiple Choice)
- A. Portal authentication
- B. 802.1x authentication
- C. Agile Controller login authentication
- D. MAC address bypass authentication
Correct Answer: A,B 🗳️
In some regions, radar systems work in the 5 GHz frequency band, which interfere with radio signals of APs working in the 5 GHz frequency band. The DFS function enables APs to detect interference on their current working channels. However, the engineers need to manually switch the APs to other channels.
- A. FALSE
- B. TRUE
Correct Answer: A 🗳️
