質問 # 163
When the CloudCampus solution is applied to small or medium-sized campus networks, which description of the access layer design is correct?
- A. Select an appropriate access switch model based on whether PoE support is required and the number of access APs.
- B. When selecting a switch, you need to calculate the number of connected APs * AP power < the power the POE switch can provide. Therefore, you need to choose a POE switch with an appropriate power supply based on the specific model and number of APs.
- C. For micro-store scenarios where AP coverage is required, APs and egress devices must be deployed in the store. APs cannot be directly connected to egress links and do not support NAT.
- D. For medium-sized supermarkets and general education scenarios with large network scales, a stacked network is recommended for the access layer. When a single access device can meet the access density of downstream terminals, a single-device network can be used at the access layer. When the upstream devices at the access layer use a stacked network, an Eth-Trunk link is recommended to connect the upstream devices. If multiple APs are required for coverage, expand AP access using POE LSW.
正解：A、B、D

質問 # 168
Which of the following statements about AP installation locations is correct? Multiple choice
- A. The material of the ceiling is generally very thin, and the impact on coverage can be ignored
- B. For aesthetic reasons, you can consider placing the AP on the ceiling.
- C. If the site has an integral suspended ceiling, the AP should be placed near the maintenance port as much as possible.
- D. When mounting on a wall or under a ceiling, drilling may be required. Please confirm with the property management whether this is feasible during the survey.
正解：A、B、C、D
質問 # 169
In a WLAN network environment, wireless client access can be controlled by selectively selecting blacklists and whitelists. Which of the following statements about blacklists and whitelists is incorrect?
- A. Use the blacklist function. If the blacklist is empty, any STA is allowed to go online.
- B. Use the whitelist function. If the whitelist is not empty, only STAs matching the whitelist can go online, and other STAs cannot go online.
- C. Use the blacklist function. If the blacklist is not empty, STAs matching the blacklist cannot go online, while other STAs can go online.
- D. Use the whitelist function. If the whitelist is empty, no STA will be allowed to go online.
正解：D
質問 # 170
The RF tuning principle includes the following steps. Which of the following is the correct order?
1) AP reports detection results
2) All APs perform neighbor detection
3) The AC enables global tuning and notifies each AP to start periodic neighbor detection.
4) AC sends the optimization results
5) After the AC waits for all APs to report neighbor information, it starts running the global tuning algorithm to allocate channel power to the APs.
- A. 1-2-3-4-5
- B. 2-1-3-5-4
- C. 3-2-1-4-5
- D. 3-2-1-5-4
正解：D

質問 # 172
Which of the following statements about directional antennas and omnidirectional antennas is correct?
- A. Omnidirectional antennas are easier to plan than directional antennas
- B. Omnidirectional antennas are preferred when the coverage distance is long.
- C. Directional antennas are suitable for coverage areas such as pedestrian streets.
- D. Try to use omnidirectional antennas for planning
正解：C、D
質問 # 173
The EAP protocol packets used in the 802.1X authentication process are BPDU packets. Huawei switches currently do not forward BPDU packets at Layer 2 by default. Therefore, if a Layer 2 switch exists between the 802.1X-enabled device and the user, Layer 2 transparent transmission must be configured on it. Otherwise, EAP packets sent by the user will not reach the authentication device, and authentication will fail.
- A. Correct
- B. Error
正解：A
質問 # 174
What technology implements application quality awareness in iMaster NCE-CampusInsight?
- A. eMDl
- B. iFit
- C. AI recognition
- D. iPCA
正解：A
質問 # 175
AP supporting optical-electric hybrid cable can support long-distance power supply over 2000 meters
- A. Correct
- B. Error
正解：B
質問 # 176
What technology does Huawei's SD-WAN solution use to achieve intelligent routing?
- A. SPR
- B. Equal-cost routing
- C. ACL
- D. Static routing
正解：A
質問 # 177
In Huawei's SD-WAN solution, iMasterNCE establishes a management channel with CPE devices through the Restful protocol.
- A. Correct
- B. Error
正解：A
質問 # 178
Which of the following statements about IPv6 terminal access solutions in WLAN services is correct?
- A. Configure different VLANs for guest SSIDs. Use the core switch or WAC as the gateway for wireless access guest terminals. Use a hybrid SLAAC solution to assign IPv6 addresses. MAC authentication is recommended.
- B. If there are terminals that cannot obtain DNS information through SLAAC, it is recommended to configure an IPv6 static address solution on the gateway.
- C. The core switch or WAC serves as the gateway for wireless access office terminals. A hybrid SLAAC solution can be used to configure IPv6 addresses for the terminals. Authentication methods include 802.1x and Portal+MA
