NEW QUESTION # 38
The AirEngine 8771-X1T has dynamic-zoom smart antennas that can switch between omnidirectional and high-density modes.
Answer: A
Explanation:
The statement is true. The AirEngine 8771-X1T uses dynamic-zoom smart-antenna technology that can adapt its radiation characteristics according to the deployment environment. In omnidirectional mode, the antenna pattern is optimized to provide broad and balanced coverage, making it appropriate for ordinary offices, corridors, classrooms, and other environments where users are distributed over a relatively large area.
In high-density mode, the antenna pattern is adjusted to concentrate radio energy more effectively within the intended service area. This reduces unnecessary signal leakage, limits interference between neighboring APs, and improves concurrent-user performance in lecture halls, conference rooms, auditoriums, and similar high- density environments.
The switching capability is more effective than using a permanently fixed antenna pattern because WLAN conditions can change as users move and traffic density increases or decreases. Huawei's training material states that dynamic-zoom smart antennas dynamically switch between omnidirectional and high-density modes, improving coverage in omnidirectional mode while strengthening the user experience in high-density scenarios. Therefore, option A is correct.
NEW QUESTION # 39
Which of the following Wi-Fi 7 APs offers PCIe card-based IoT functions?
Answer: C
Explanation:
The AirEngine 6776I-X6TH is the model designed to provide PCIe card-based IoT expansion. The PCIe interface enables an appropriate IoT expansion card to be installed so that the AP can support additional wireless or sensing technologies according to the deployment requirement. This allows the same physical access infrastructure to deliver enterprise Wi-Fi and IoT connectivity.
The capability is useful in retail, healthcare, education, manufacturing, and asset-management environments, where technologies such as Bluetooth, RFID, Zigbee, electronic shelf labels, location services, or specialized sensing systems may need to coexist with the WLAN. A modular card design is preferable when an organization requires selectable or upgradeable IoT functions rather than only fixed integrated capabilities.
Huawei's Wi-Fi and IoT convergence architecture reduces repeated cabling, separate power systems, and independently managed wireless networks. It enables an IoT-capable AP to provide the installation position, power, management connectivity, and uplink data channel required by IoT modules. Among the models listed, the AirEngine 6776I-X6TH is the PCIe card-based IoT model. Therefore, option A is correct.
NEW QUESTION # 40
Which of the following statements are true about traffic encryption on SD-WAN links?
Answer: A,B
Explanation:
Huawei SD-WAN allows encryption to be controlled by virtual network and by specific device relationships.
When encryption is enabled for a VN, the overlay data channels carrying that VN's traffic use IPsec protection across the relevant WAN links. This provides consistent isolation and confidentiality for the department or service represented by that VN.
Encryption can also be enabled between selected devices or sites. In that case, secure data channels are established for traffic exchanged between those specified endpoints, while other device relationships can continue using GRE without IPsec according to their policies.
Application-specific encryption, as described in option C, is not the supported control granularity. Application identification can influence intelligent traffic steering, QoS, and security-policy selection, but it does not mean that only the payload of a selected application is independently encrypted inside an otherwise unencrypted SD-WAN tunnel.
A transport network is an underlay WAN such as MPLS or the Internet. Enabling encryption is an overlay tunnel policy rather than a mechanism that encrypts all traffic belonging to an entire TN. Huawei distinguishes TNs as underlay networks and GRE or IPsec VPNs as overlay data channels. Therefore, only A and B are correct.
NEW QUESTION # 41
On a large campus network, inter-WAC roaming should be avoided as much as possible to ensure the roaming experience.
Answer: A
Explanation:
The statement is true as a WLAN design recommendation. Inter-WAC roaming is supported, but it introduces more control-plane interaction and forwarding complexity than intra-WAC roaming. The Home WAC and Foreign WAC must belong to the same mobility group, synchronize station and AP information, and establish an inter-WAC CAPWAP tunnel for control information and, in some scenarios, service forwarding.
Additional synchronization, tunnel processing, route handling, and failure dependencies can increase roaming delay and complicate troubleshooting. This is especially relevant for delay-sensitive applications such as voice, video, automated guided vehicles, and real-time production systems. A better design places APs between which users frequently move under the same WAC wherever controller capacity and physical topology permit.
Avoiding inter-WAC roaming does not mean disabling the function entirely. Large campuses may require multiple WACs for scale, redundancy, or geographic distribution. Mobility groups should still be configured for unavoidable cross-controller movement. However, buildings, floors, and continuous roaming areas should be assigned carefully so that normal roaming remains intra-WAC. Therefore, the recommendation in the statement is correct, and the answer is True.
NEW QUESTION # 42
Which of the following is not part of an IFIT measurement model?
Answer: C
Explanation:
The Network Management System is not an element of the IFIT measurement model. An IFIT measurement definition identifies the traffic to be measured, the locations where measurement actions occur, and the direction in which the flow is evaluated. The measurement flow specifies the target packets, usually through flow-identification fields. Measurement points define where packets are marked, counted, timestamped, or reported, such as ingress, transit, and egress nodes. Measurement direction distinguishes forward and reverse monitoring so that packet loss, delay, and path behavior can be analyzed correctly for each direction.
An NMS or controller remains operationally important because it creates measurement tasks, distributes configurations, receives telemetry data, correlates the results, and presents fault-location information.
However, it is the management and analysis system surrounding the measurement model, not one of the model's constituent measurement parameters.
Huawei positions IFIT as a high-precision telemetry mechanism used to delimit and locate application-quality faults. The training material highlights IFIT's capability to locate faults rapidly and detect packet loss with extremely high reliability. Therefore, the component that is not part of the measurement model is the NMS.
