NEW QUESTION # 20
Which of the fallowings is not an IPv6 address type?
- A. Anycast address
- B. Unicast address
- C. Multicast address
- D. Broadcast address
Answer: D
Explanation:
Explanation
Broadcast address is not an IPv6 address type. IPv6 does not support broadcast addressing, but uses multicast addressing instead. The other options are valid IPv6 address types. Unicast address identifies a single interface, multicast address identifies a group of interfaces, and anycast address identifies multiple interfaces but delivers packets to only one of them.

NEW QUESTION # 21
Which of the following statements are true about data collection of IMaster NCE-Campuslnslght? (Select All that Apply)
- A. iMaster NCE-Campuslnsight uses telemetry to Implement efficient data collection.
- B. Calculated data can be displayed on iMaster NCE-Campuslnsight only after a license Is loaded on the device management page.
- C. To collect data from WLAN devices, ensure that WACs can communicate with the southbound IP address of iMaster NCE-Campuslnsight. APs do not need to communicate with the southbound IP address of iMaster NCE-Campuslnsight.
- D. The UTC time of iMaster NCE-Campuslnsight must be the same as that of its managed devices.
Answer: A,C
Explanation:
Explanation
B is false because calculated data can be displayed on iMaster NCE-CampusInsight without loading a license on the device management page. The license only affects the number of devices that can be managed by iMaster NCE-CampusInsight.
D is false because the UTC time of iMaster NCE-CampusInsight does not need to be the same as that of its managed devices. However, it is recommended that they use the same time zone to avoid confusion.

NEW QUESTION # 30
Drag the short-range wireless IoT technologies on the left to their corresponding descriptions on the right.
Answer:
Explanation:
Explanation
According to the Huawei documents and resources, the definitions of the short-range wireless IoT technologies are as follows:
ZigBee: IEEE 802.15.4-based wireless communication technology is a short-range, and low-power wireless communication technology that supports star, mesh, and hybrid networking.
Bluetooth: With the emergence of IoT industries such as smart wearables, smart home, and Internet of Vehicles, short-range communication technologies are attracting more and more developers.
REID: Its basic principle is to automatically identify objects based on the transmission characteristics of radio signals and space coupling (inductance or electromagnetic coupling) or radar reflection.
Wi-Fi: Wireless networking technology based on IEEE 802.11 is the most popular WLAN technology.
Therefore, ZigBee - 1, Bluetooth - 3, REID - 2, Wi-Fi - 4 is the correct answer. References: :

NEW QUESTION # 31
Assume that a large enterprise needs to deploy a WLAN to provide wireless access for both employees and guests. However, guest data may pose security threats on the network. Which of the following networking modes is applicable to this scenario?
- A. Fat AP networking
- B. Leader AP networking
- C. Navi WAC Networking
- D. Mesh networking
Answer: C
Explanation:
Explanation
Navi WAC networking is a networking mode that uses a WLAN Access Controller (WAC) to manage and control APs. It can provide different authentication and security policies for different user groups, such as employees and guests. Guest data is isolated from the internal network to prevent security threats.

NEW QUESTION # 32
Which of the following statements about the access layer design are true when Huawei's CloudCampus Solution is applied to small and midsize campus networks? (Select All that Apply)
- A. For relatively large networks in midsize shopping malls, supermarkets, and primary/secondary education campuses, it is recommended that stack networking be used at the access layer. If a single device can provide sufficient access capacity for downstream terminals, single-device networking can be used at the access layer. If the upstream devices of access-layer devices are stacked, it is recommended that Eth-Trunks be used to connect to such upstream devices. If more APs need to be deployed, use the PoE switch to increase the number of APs to be connected.
- B. In the mini-store scenario, APs and egress devices must be deployed if Wi-Fi coverage is required. APs cannot directly connect to egress links and do not support NAT.
- C. Select appropriate models of access switches based on whether PoE support is required and how many APs need to access the network.
- D. When selecting a switch, ensure that the following condition is met; Number of connected APs x AP power ^ Power provided by the PoE switch. Therefore, select PoE switches with a proper power supply based on the AP model and quantity.
Answer: C,D
Explanation:
Explanation
A is false because in the mini-store scenario, APs can directly connect to egress links and support NAT if Wi-Fi coverage is required. There is no need to deploy egress devices separately.

Fingerprint-based positioning technology is a method that uses the signal strength or phase difference of wireless signals to locate objects. There are two types of fingerprint-based positioning technology: virtual fingerprint-based positioning and real fingerprint-based positioning. In virtual fingerprint-based positioning, the positioning engine generates a virtual fingerprint library through calculations based on the AP deployment and environment information. In real fingerprint-based positioning, the fingerprint map is obtained through onsite information collection.

NEW QUESTION # 38
In a VRRP HSB scenario, if the VRRP preemption delay is set to a small value, which of the following problems may occur after a master/backup switchover? (Select All that apply)
- A. A master/backup switchback is triggered too quickly.
- B. Service data on the master and backup WACs is lost.
- C. The batch backup process cannot be started.
- D. Backup information is incomplete.
Answer: A,D
Explanation:
Explanation
According to the Huawei documents and resources, the VRRP preemption delay is the time that an AC waits before preempting another AC with a lower priority. If the VRRP preemption delay is set to a small value, the following problems may occur after a master/backup switchover:
B: A master/backup switchback is triggered too quickly. If the master AC recovers soon after a switchover, it may preempt the backup AC again and become the master AC. This may cause frequent switchovers and affect network stability C: Backup information is incomplete. If the backup AC takes over services from the master AC too quickly, it may not have received all the data synchronized from the master AC through HSB. This may cause service interruption or data loss Therefore, B and C are the correct answers. References:

NEW QUESTION # 40
Drag the Huawei's wireless positioning solutions on the left to their corresponding features and application scenarios on the right.
Answer:
Explanation:
Explanation
According to the Huawei documents and resources, the features and application scenarios of the wireless positioning solutions are as follows:
Wi-Fi terminal positioning: Performs network-side positioning generally based on the RSSI, but provides low positioning accuracy. This method applies to scenarios such as precision marketing and customer flow analysis in shopping malls.
Bluetooth tag positioning: Runs based on the built-in Bluetooth module of an AP. The AP reports data to a positioning engine for location resolution. This positioning technology provides low positioning accuracy and applies to asset positioning and personnel positioning scenarios.
UWB positioning: Provides high positioning accuracy, and is applicable to scenarios that require high accuracy, such as intelligent manufacturing, warehousing logistics, and mechanical manufacturing.
Bluetooth terminal positioning: Runs based on the built-in Bluetooth module of an AP, which can be implemented on either the network side or terminal side.
Therefore, Wi-Fi terminal positioning - 3, Bluetooth tag positioning - 4, UWB positioning - 2, Bluetooth terminal positioning - 1 is the correct answer. References: :

After multicast-to-unicast conversion is enabled on an AP's air interface, which of the followings is the destination MAC address of multicast packets sent over the air interface?
- A. MAC address of the multicast source
- B. Multicast MAC address
- C. MAC address of a STA
- D. Broadcast MAC address
Answer: C
Explanation:
Explanation
After multicast-to-unicast conversion is enabled on an AP's air interface, the destination MAC address of multicast packets sent over the air interface is changed to the MAC address of a STA that has joined the multicast group. This improves the transmission efficiency and reliability of multicast packets.
