NEW QUESTION # 29
Huawei provides an innovative technology that can maintain smooth video when traffic packet loss between enterprise branches reaches up to 20%. Which technology provides this capability?
Answer: C
Explanation:
A-FEC, or Adaptive Forward Error Correction, is the correct technology. It protects delay-sensitive traffic by adding calculated redundant packets to the original packet stream. If some original packets are lost during WAN transmission, the receiving edge device can reconstruct them using the surviving original and redundant packets rather than waiting for end-to-end retransmission.
The key distinction between ordinary FEC and A-FEC is adaptation. With A-FEC, the receiving device reports real-time packet-loss and continuous-loss information to the transmitting device through FEC acknowledgement messages. The transmitting edge then dynamically increases or decreases the redundancy ratio according to actual network conditions. This provides stronger recovery during severe loss while avoiding unnecessary bandwidth overhead when link quality improves. Huawei describes this feedback- controlled adjustment as a mechanism that can alleviate or eliminate the impact of packet loss.
IFIT and IPCA are primarily measurement and service-quality analysis technologies; they do not reconstruct lost video packets. Fixed FEC does not adapt its redundancy level as effectively to changing loss conditions.
Therefore, the technology intended for smooth video under packet loss of up to 20% is A-FEC.
NEW QUESTION # 30
Which of the following are Target Wake Time (TWT) technologies?
Answer: A,B,C
Explanation:
Broadcast TWT, Individual TWT, and Implicit TWT are valid Target Wake Time concepts. Individual TWT establishes a wake schedule between an AP and a specific station. Broadcast TWT advertises scheduling information that multiple stations can use, reducing individual negotiation overhead and coordinating groups of devices. An implicit TWT agreement defines a repeating schedule in which subsequent wake times are calculated from the agreed wake interval instead of being renegotiated for every service period.
These mechanisms allow stations, particularly battery-powered IoT devices, to sleep for predictable periods and wake only when transmission or reception is scheduled. TWT consequently reduces power consumption, channel contention, collisions, and unnecessary medium access in dense WLAN environments. Research describing IEEE 802.11ax TWT confirms that the mechanism schedules station transmission periods and allows stations to remain asleep outside their negotiated service periods.
"Multicast TWT" is not one of the standard TWT concepts represented by this question. Broadcast scheduling can cover multiple stations, but that does not create a separate mechanism formally identified here as Multicast TWT. Therefore, the correct answers are A, B, and C.
NEW QUESTION # 31
On which public cloud can the AR6700V-L running R024C10 not be deployed?
Answer: D
Explanation:
For the R024C10 software release specified in the question, the AR6700V-L cannot be deployed on Google Cloud Platform. The supported environments represented by this release and question are Amazon Web Services, Oracle Cloud, and Microsoft Azure.
Public-cloud support for a virtual CPE is release-specific. A virtual router requires more than generic virtual- machine compatibility. Huawei must provide or validate the appropriate cloud image, virtual network- interface drivers, deployment template, bootstrap mechanism, licensing integration, resource specifications, and controller-registration process for each cloud platform. Therefore, support for one KVM- or VMware- based environment does not automatically mean that every public-cloud provider is supported.
A cloud-hosted virtual CPE enables branches to establish overlay connectivity directly with cloud workloads and allows the controller to provide unified management and policy orchestration for physical and virtual edge devices. Huawei describes this model as deploying a virtual SD-WAN router on a public cloud to implement branch-to-cloud interconnection and unified policy orchestration. Under the R024C10 compatibility matrix tested by this question, GCP is excluded. Therefore, option B is correct.
NEW QUESTION # 32
Which of the following statements is false?
Answer: D
Explanation:
Option C is false. Traditional QoS can classify traffic and provide differentiated treatment for service categories such as voice, video, and ordinary data. It normally performs classification, marking, policing, shaping, congestion avoidance, and queue scheduling on an interface. This provides service-level differentiation but does not deliver sufficiently refined simultaneous management across multiple users and multiple applications.
Huawei's material explicitly states that traditional QoS schedules traffic based on port bandwidth and can differentiate traffic according to service levels, but it is difficult to distinguish traffic by user. It also states that traditional QoS cannot manage and schedule traffic from multiple services and multiple users simultaneously.
HQoS addresses this limitation through hierarchical, multi-level queues. For example, a parent level can allocate bandwidth to departments, VPNs, sites, or users, while child queues prioritize applications such as voice, video, email, and best-effort traffic. Huawei describes HQoS as hierarchical scheduling that differentiates both services and users. Therefore, statements A, B, and D are correct, while statement C incorrectly attributes an HQoS capability to traditional QoS.
NEW QUESTION # 33
Which of the following deployment modes are supported by AR routers?
Answer: B,C,D
Explanation:
AR routers support registration query center-based deployment, email-based deployment, and DHCP Option
148-based deployment. In registration query center deployment, the router obtains basic network connectivity, resolves or contacts Huawei's registration service, retrieves the address and port of iMaster NCE, and then initiates registration. Huawei identifies AR routers, firewalls, switches, and APs as applicable devices for this method.
Email-based deployment is a major SD-WAN ZTP method for AR routers operating as CPEs. An administrator creates the site and ZTP configuration on iMaster NCE and sends a deployment URL to the onsite engineer. After the URL is opened and the parameters are written to the router, the device connects to the WAN and automatically registers with the controller.
DHCP Option 148 can provide the controller's southbound IP address and port number to an IPv4 AR router, enabling automatic registration. Barcode scanning through the CloudCampus APP is specifically presented as an AP onboarding method, not an AR-router deployment method. Therefore, A, C, and D are correct.
