NEW QUESTION # 25
On which public cloud can the AR6700V-L running R024C10 not be deployed?
Answer: A
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 # 26
Which of the following encryption algorithms is used by WPA3?
Answer: A
Explanation:
The intended answer is AES-256. In certification material, this question normally refers to the enhanced WPA3-Enterprise 192-bit security suite, which uses the GCMP-256 data-protection algorithm based on AES-
256, together with stronger integrity and key-management components. AES-512 is not a standardized AES variant, and RC4 is the obsolete stream cipher associated with legacy WEP and TKIP-era protection rather than WPA3.
There is an important technical qualification: WPA3 is a family of certification modes, not one universal cipher suite. WPA3-Personal commonly uses Simultaneous Authentication of Equals for password- authenticated key establishment and requires CCMP-128, which is based on AES-128. WPA3-Enterprise 192- bit mode, however, uses AES-256 in GCM mode. Therefore, the original wording is broader than it should be.
A technically precise version would ask which algorithm is associated with the WPA3-Enterprise 192-bit security suite. Under the intended Huawei examination scope and the supplied single-choice options, option B is correct. That distinction is crucial when interpreting this simplified examination item.
NEW QUESTION # 27
What is the maximum number of access units supported by a central switch on a passive Ethernet network (PEN)?
Answer: B
Explanation:
A central switch in the relevant passive Ethernet network architecture supports a maximum of 48 access units.
The architecture replaces a conventional multi-layer access design with a centralized switch and distributed remote or access units. The access units function as extensions of the central switch's ports, simplifying device management, configuration, and topology maintenance.
Huawei's CloudEngine S5731-H fixed central-switch specification provides models with 24 or 48 hybrid optical-electrical downlink ports. The 48-port model can therefore directly manage up to 48 associated access or remote units under the design limits represented by this question. The same hybrid links can provide data transmission and remote PoE power, enabling access units to be installed closer to terminals without requiring conventional active aggregation equipment at every location.
The central switch automatically discovers the topology, while remote units behave as extended ports rather than independently managed switches. This reduces management nodes and simplifies a traditional three- layer network into a two-layer architecture. The larger values of 64, 72, and 96 exceed the supported maximum for the specified central-switch implementation. Therefore, option C is correct.
NEW QUESTION # 28
Which of the following statements is false about GRE over IPsec?
Answer: D
Explanation:
Option B is false because it reverses the encapsulation behavior. In IPsec transport mode, the IPsec security header is inserted after the existing IP header; a new outer IP header is not normally added. In tunnel mode, the complete original IP packet is encapsulated and a new outer IP header is added. Tunnel mode therefore generally introduces greater overhead and produces a longer packet than transport mode, not the reverse.
The remaining statements are correct. IPsec supports both transport and tunnel modes. GRE over IPsec performs GRE encapsulation first, allowing GRE to transport the original payload, and then applies IPsec protection to the resulting GRE packet. The IPsec security association is established between the GRE tunnel endpoints, protecting the GRE-encapsulated traffic as it traverses an untrusted transport network.
Huawei SD-WAN data channels can use either GRE or GRE over IPsec. GRE provides flexible overlay encapsulation, while IPsec adds confidentiality, integrity, origin authentication, and anti-replay protection for site-to-site traffic. Huawei specifically identifies IPsec encryption as the mechanism securing site-to-site SD- WAN services.
NEW QUESTION # 29
Which of the following WLAN networking solutions is recommended when there are 15,000 wireless terminals on the customer network?
Answer: C
Explanation:
A network serving 15,000 wireless terminals is a large-scale WLAN and should use a standalone WAC solution. A dedicated WAC provides independent controller resources, scalable AP and user management, centralized WLAN policy control, and the ability to deploy controller redundancy without tying wireless- control capacity directly to a specific core-switch service card.
Huawei recommends a standalone WAC when the wireless network scale is large or when the wireless network is deployed independently over an existing wired campus. The WAC is typically connected to the aggregation or core layer in off-path mode, and VRRP hot standby can be used to improve reliability.
Native WAC solutions are valuable for unified wired and wireless management, authentication, forwarding, and policy enforcement. However, for a very large number of wireless terminals, the controller platform must be selected according to user, AP, traffic, and forwarding-capacity specifications. A standalone WAC allows the wireless control plane to be sized and expanded independently.
Option C provides the dedicated WAC together with the required core and aggregation or access infrastructure. Therefore, it is the recommended architecture for 15,000 wireless terminals.
