Question 3

DRAG DROP
Drag the reasons for AP onboarding failures on the left to the corresponding troubleshooting
operations on the right.

Answer:

None

User Votes:

Explanation:
According to the Huawei documents and resources, the troubleshooting operations for the AP
onboarding failures are as follows:
APS fail to be authenticated by the WAC: Whitelist the APS. The WAC can authenticate APs based on
their MAC addresses or SNs. If an AP is not whitelisted on the WAC, it cannot be authenticated and
onboarded.
License resources on the WAC are insufficient: Expand the license capacity. The WAC can manage a
limited number of APs based on its license. If the license resources are insufficient, some APs cannot
be onboarded.
APS fail to obtain IP addresses: Check the DHCP server. The APs need to obtain IP addresses from a
DHCP server before they can communicate with the WAC. If the DHCP server is not configured or
reachable, the APs cannot obtain IP addresses and onboard.
APS fail to ping the WAC: Check the network between the WAC and APS. The APs need to ping the
WAC to discover its IP address and establish a CAPWAP tunnel. If there is a network problem
between the WAC and APs, such as incorrect VLAN configuration or firewall blocking, the APs cannot
ping the WAC and onboard.
Therefore, APS fail to be authenticated by the WAC - c, License resources on the WAC are insufficient
- b, APS fail to obtain IP addresses - d, APS fail to ping the WAC - a is the correct answer. Reference: :

Question 4

Which of the following statements about WLAN roaming and signal strength Is false?

  • A. Smart roaming can be enabled on the WAC to help ST As roam and associate with APs with better signals.
  • B. Generally, a STA roams when it detects that the signal strength is less than -75 dBm.
  • C. STAs can roam between WACs in dual-link HSB mode.
  • D. In most cases, the signal strength of a STA should range from -45 dBm to -65 dBm.

B

Question 5

When calculating the number of APs, you can divide the total required bandwidth by the maximum
bandwidth of a single AP.

  • A. True
  • B. False
Answer:

B

User Votes:
A
50%
B
50%

Explanation:
When calculating the number of APs, you cannot simply divide the total required bandwidth by the
maximum bandwidth of a single AP. You also need to consider other factors such as signal coverage
area, user density, interference level, and application type.

Question 6

Which of the following statements are true about the WLAN site survey In different typical
scenarios? (Select All that Apply)

  • A. In a classroom scenario. If the walls are made of reinforced concrete, the signal attenuation Is high. In this case, you are advised to test the attenuation during the site survey. Additionally, pay attention to the locations of ELV rooms in the teaching building.
  • B. In an office scenario, the load-bearing columns and partitions affect the signal coverage. If an integrated ceiling is used, deploy APs near maintenance entrances. If a metal ceiling is used, mount APs on the ceiling or wall.
  • C. In a ward-round scenario, high requirements are posed on the coverage field strength, roaming effect, and bandwidth. Determine the interference of medical equipment and the areas where Wi-Fi signals are not allowed.
  • D. In a stadium scenario, the onsite environment is complex and cabling is difficult. Therefore, confirm with the property management company about ELV rooms and cabling. If the transmission distance is too long, consider deploying more switches. During the survey, focus on the interference between APs and AP mounting modes.

Question 7

In the early phase of a project, after the project requirements are clarified, the project owner should
Checklist to describe the customer's requirements. (Capitalize the first letter of each word.)

Answer:

Customer
Requirement
Specification


Explanation:
Customer Requirement Specification (CRS) is a document that needs to be output after the project
requirements are clarified. The CRS describes the customer’s requirements in detail and serves as the
basis for subsequent project design and delivery.

During a project lifecycle, the______ document needs to be output after the high level design be
output after the low level design is complete. (Enter the acronyms in capital letters.)

Answer:

ATP

User Votes:

Explanation:
ATP stands for Acceptance Test Plan, which is a document that needs to be output after the low level
design is complete. The ATP describes the acceptance criteria and test cases for the project.

  • A. Capacity planning
  • B. Network design
  • C. AP position planning
  • D. Deployment planning
Answer:

C

Explanation:
According to the Huawei documents and resources, the HLD phase is the high-level design phase of a
WLAN project. It involves the following items:
Capacity planning: Determines the number and types of devices required for the WLAN network
based on the customer’s requirements and network scale.
Network design: Designs the network topology, IP addressing scheme, VLAN division, security
policies, and other network parameters for the WLAN network.
Deployment planning: Plans the deployment sequence, schedule, resources, and risks for the WLAN
project.
AP position planning is not involved in the HLD phase. It is part of the LLD phase, which is the low-
level design phase of a WLAN project. It involves the detailed design of AP positions, antenna types,
channel allocation, power adjustment, and other wireless parameters for the WLAN network.
Therefore,
C
is
