NEW QUESTION # 53
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 # 54
Which of the following statements are true about selecting network access authentication points?
Answer: B,C,D
Explanation:
Authentication points should generally be placed on access devices close to the terminals. For wireless users, the AP or WLAN access device is the natural admission point because it directly controls the station's wireless association and service access. For wired users, the access switch directly connects the endpoint and can enforce 802.1X, MAC-address authentication, VLAN authorization, ACLs, and security-group policies.
Huawei recommends access devices as authentication points for employees and specifically recommends access switches as authentication points for wired dumb terminals using MAC-address authentication.
Deploying enforcement close to endpoints prevents unauthenticated or unauthorized traffic from traversing deeper into the campus network. It also improves fault isolation, policy granularity, and scalability because admission processing is distributed across access devices.
Option A is incorrect. A centralized authentication point can simplify configuration and policy management, but it does not inherently provide higher performance. It can create concentrated processing pressure, enlarge the Layer 2 scope, and allow unauthenticated traffic to travel farther before being evaluated. Therefore, the recommended principles are represented by B, C, and D.
NEW QUESTION # 55
In hierarchical networking, which of the following devices is used for communication between different areas?
Answer: C
Explanation:
A border device, or more precisely a device at a border site, provides communication between different areas in a hierarchical SD-WAN topology. The hierarchical model divides a large WAN into multiple areas. Each area can independently use a hub-spoke or full-mesh topology, while selected border sites connect the local area to a centralized backbone area.
When a non-border site receives a route originating in another area, the route's next-hop site ID is changed to the border site in its own area. The local border device then forwards traffic toward the border site in the destination area or toward an interconnected hub site. Ordinary edge devices provide connectivity for their own sites but do not automatically perform cross-area transit.
Huawei describes border sites as members of both the level-2 area network and the level-1 backbone network.
These sites collectively implement interconnection between areas. Huawei further explains that inter-area routes point to border sites and recommends two border sites operating in active/standby mode for reliability.
Therefore, the correct answer is B.
NEW QUESTION # 56
Which of the following statements is false about Layer 3 roaming?
Answer: D
Explanation:
Option B is false because a station retains its original IP address during Layer 3 roaming. Preserving the IP address is essential for maintaining active application sessions when the station moves between APs associated with different service VLANs, Layer 2 domains, and gateways. Huawei's training diagram shows the same station IP address before and after roaming, while the service VLAN changes.
When the STA initially accesses the WLAN, a Home AP or HAP is selected for it. After the STA roams to a Foreign AP, the new AP obtains the station information and establishes the required forwarding relationship with the HAP. In direct-forwarding implementations, the STA's traffic is encapsulated and forwarded to the HAP, which preserves access through the original network and gateway.
Therefore, A and C accurately describe HAP-based Layer 3 roaming. Option D is also correct: the APs use the same SSID and authentication mode but different service VLANs. The station's IP address does not change, so B is the false statement.
NEW QUESTION # 57
What are the modes of the HSR RedBox?
Answer: A,B,C,D
Explanation:
An industrial RedBox can provide all four listed interconnection modes. In HSR-SAN mode, it connects a singly attached node that does not natively support High-availability Seamless Redundancy to an HSR network. The RedBox duplicates frames entering the HSR domain and removes duplicate frames before delivering traffic to the SAN.
HSR-PRP mode interconnects an HSR ring with a Parallel Redundancy Protocol network while preserving seamless redundancy. PRP-PRP mode couples two PRP network domains, while HSR-HSR mode connects separate HSR rings. Depending on the implementation, the HSR-HSR interconnection function may also be described as a QuadBox function because four HSR-facing ports can be involved.
The essential RedBox responsibilities are frame conversion, duplication, duplicate elimination, sequence- number handling, and prevention of unintended forwarding loops between redundancy domains. HSR and PRP use compatible duplicate-identification principles, enabling controlled interconnection between these network types without introducing a single point of failure. RedBoxes also provide redundant connectivity for devices that have only one ordinary Ethernet interface.
