NEW QUESTION # 11
Which 5G-Advanced capabilities does the AR5710-S8T1XWE-NRGL support?
Answer: A,B,C,D
Explanation:
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.
NEW QUESTION # 12
A label stack is an ordered set of labels. MPLS supports a maximum of three layers of nested labels.
Answer: A
Explanation:
The statement is false. An MPLS label stack is an ordered sequence of label-stack entries, with the top label processed first and the bottom identified by the Bottom-of-Stack bit. However, the MPLS architecture does not define a universal maximum of three nested labels. An MPLS forwarding operation may replace the top label, remove it, or push one or more additional labels onto the stack.
Practical label depth is constrained by device implementation, forwarding ASIC capabilities, packet size, and the number of network functions being encoded. A conventional MPLS VPN may use two labels: a transport label and a VPN label. More advanced deployments can add labels for traffic engineering, segment routing, entropy, service chaining, or hierarchical transport. This can produce stacks deeper than three entries.
Therefore, "three layers" may describe a limitation of a particular platform, software version, or deployment design, but it is not an MPLS protocol maximum. RFC 3032 defines the stack as a sequence of four-byte entries and explicitly allows one or more entries to be pushed without specifying a three-label ceiling.
NEW QUESTION # 13
Which of the following can be prevented by using the unauthorized access prevention function of Huawei switches?
Answer: B,C
Explanation:
Huawei switches' unauthorized access prevention function can prevent users from connecting unauthorized hubs and sharing network access through unauthorized Wi-Fi hotspots. An unauthorized hub allows multiple terminals to enter the network through a port intended for a single managed endpoint. This can bypass normal terminal-count limitations, admission controls, and access-policy enforcement.
Unauthorized Wi-Fi hotspot sharing occurs when a user connects an authenticated endpoint to the enterprise network and then enables hotspot or connection-sharing functionality. Other terminals can subsequently access the network through that endpoint without completing the required authentication process. Huawei switches can analyze terminal behavior, MAC-address relationships, packet characteristics, and access patterns to identify and restrict this behavior.
A USB flash drive is a local storage device and does not provide Ethernet network access, so option A is unrelated to switch-based unauthorized network access prevention. An unauthorized router is normally controlled through device identification, NAC, port security, or explicit access policies rather than the specific hub and hotspot-sharing prevention function described by this question.
Huawei intelligent terminal management combines terminal identification, authorization, traffic analysis, and bogus-terminal detection to achieve visualized access and prevent unauthorized connectivity.
NEW QUESTION # 14
Which of the following are WAN interconnection models for multi-branch campus networks?
Answer: A,C,D
Explanation:
Huawei SD-WAN supports full-mesh, hub-spoke, and partial-mesh interconnection models. In a full-mesh topology, every site can communicate directly with the other sites. This model minimizes intermediate forwarding and is appropriate when branches frequently exchange latency-sensitive traffic such as voice, video, or collaborative application data.
In a hub-spoke topology, branch sites communicate with a central headquarters or data-center hub. Branch-to- branch traffic normally traverses that hub. The model is simple, scalable, and suitable for enterprises whose applications and shared resources are concentrated at headquarters.
Partial-mesh is used when most sites can communicate directly but some sites lack direct underlay connectivity or do not require direct tunnels. Those sites can communicate through a redirect or intermediate site. Huawei describes full-mesh, hub-spoke, and partial-mesh as supported topology designs and explains the role of a redirect site in partial-mesh networking.
"Partial-spoke" is not a defined SD-WAN topology model. A spoke is a role within hub-spoke networking rather than an independent partial-spoke topology. Therefore, A, B, and D are correct.
NEW QUESTION # 15
Which of the following statements are true about wireless traffic forwarding modes on a fabric wireless network?
Answer: A,B,C,D
Explanation:
All four statements correctly describe the trade-offs between direct and tunnel forwarding. With direct forwarding, an AP sends service traffic directly to the upstream network rather than encapsulating it in a CAPWAP data tunnel to the WAC. This eliminates unnecessary detours, avoids creating a WAC bandwidth bottleneck, reduces WAC load, and generally provides higher forwarding efficiency.
However, on a fabric network, Layer 3 roaming across different edge nodes may require the original edge or another designated device to remain the home agent. The resulting forwarding path and state synchronization can slightly affect roaming performance, making direct forwarding less suitable for extremely roaming- sensitive deployments. Huawei's material explains that after Layer 3 roaming in direct-forwarding mode, traffic may continue to be forwarded through the home agent.
Tunnel forwarding sends AP service traffic through CAPWAP tunnels to the WAC. This simplifies centralized policy enforcement, security control, and traffic management. Its disadvantage is that all wireless traffic may detour through the WAC, increasing forwarding pressure and potentially creating a performance bottleneck.
