Which of the following WLAN networking solutions is recommended when there are 15,000 wireless terminals on the customer network?
Correct Answer: B
Question 12
Which of the following statements are true about traffic encryption on SD-WAN links?
Correct Answer: A,B
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.
Question 13
Which of the following functions is supported by the AR6177?
Correct Answer: C
The distinguishing function supported by the AR6177 is VDSL. VDSL, or Very-high-bit-rate Digital Subscriber Line, enables a branch router to obtain WAN connectivity over existing copper telephone infrastructure. It is appropriate for small branches and distributed sites where Ethernet private lines, fiber, or mobile connections are unavailable or commercially impractical. The AR6177 can terminate the VDSL access circuit and provide routing, NAT, DHCP, VPN, and other branch-gateway functions for the connected LAN. In this single-answer question, Wi-Fi and PoE are not the defining integrated capabilities of the AR6177 model. Similarly, the complete combination of IPS, antivirus, and URL filtering belongs to a security-enhanced product profile rather than the function used to distinguish the AR6177. Huawei's campus design material recognizes DSL links as a specific WAN-access category and notes that deployments involving complex or low-speed links, including DSL, may require an appropriate branch-device deployment method. The model is therefore selected when direct VDSL-based WAN access is required. Consequently, VDSL is the supported capability intended by this question, and option C is correct.
Question 14
On which public cloud can the AR6700V-L running R024C10 not be deployed?
Correct Answer: B
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.
Question 15
Which 5G-Advanced capabilities does the AR5710-S8T1XWE-NRGL support?
Correct Answer: A,B,C,D
The AR5710-S8T1XWE-NRGL supports all four listed 5G-Advanced capabilities. Support for 3GPP Release 16 enables enhanced 5G New Radio functions and provides the standards foundation for improved mobile- WAN capacity, reliability, and service performance. Carrier aggregation combines multiple component carriers to increase available throughput. Downlink 3CC allows three component carriers to be aggregated for received traffic, while uplink 2CC combines two carriers for transmitted traffic. This is valuable for high-bandwidth branch access, video backhaul, and mobile private- network scenarios. Support for eight APNs permits multiple logically separated mobile services or provider profiles to be configured. Different APNs can represent enterprise services, management traffic, production systems, backup connectivity, or isolated customer networks. Global-frequency-band support improves deployment flexibility across countries and carrier networks, subject to local spectrum regulation and the supported modem variant. Huawei SD-WAN can use 5G as a primary, secondary, or bypass link and supports combinations such as dual 5G and 5G plus wired connectivity for service assurance. Therefore, NR Release 16, carrier aggregation, eight APNs, and global frequency bands are all supported.
