質問 # 44
Traffic can be forwarded directly between the two PRP ports of a PRP RedBox.
正解：B
解説：
The statement is false. In Parallel Redundancy Protocol, LAN A and LAN B must remain two separate, failure-independent networks. A PRP RedBox connects a singly attached node or conventional network to both parallel LANs and behaves toward the PRP network like a doubly attached node. It duplicates outgoing frames and transmits one copy through each PRP port. For incoming traffic, it accepts the first valid copy and discards the later duplicate before forwarding the frame through its interlink port.
The RedBox must not operate as a normal bridge that directly forwards frames from its LAN A port to its LAN B port. Doing so would connect the two redundant LANs, potentially creating loops, duplicate propagation, broadcast amplification, and a common failure path. That would defeat the fundamental PRP requirement that failure or disruption in one LAN must not affect the other.
The original video contains the typing error "PPR RedBox"; the correct term is PRP RedBox , meaning Parallel Redundancy Protocol Redundancy Box. PRP topology requires two separate networks with no direct links between them, while the RedBox provides controlled redundant attachment for non-PRP devices.
質問 # 45
Which of the following encryption algorithms is used by WPA3?
正解：B
解説：
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.
質問 # 46
Which of the following statements is false about GRE over IPsec?
正解：B
解説：
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.
質問 # 47
Which of the following statements are true about wireless traffic forwarding modes on a fabric wireless network?
正解：A、B、C、D
解説：
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.
質問 # 48
Which of the following protocol data packets can be encapsulated in a VPN using GRE?
正解：A、B、C、D
解説：
GRE is a multiprotocol encapsulation mechanism and can carry all the listed packet types. It inserts a GRE header around the original payload and then places the resulting GRE packet inside a delivery-protocol packet. Because the GRE header contains a Protocol Type field identifying the encapsulated payload, GRE is not restricted to ordinary IPv4 unicast traffic.
IPv6 packets can be transported as GRE payloads when supported by the tunnel endpoints. IP unicast traffic is the most common use case. GRE can also carry IP multicast and broadcast packets, which is one of its major advantages over basic IPsec tunnel selectors that traditionally focus on IP unicast traffic. This enables routing protocols, multicast applications, discovery traffic, and other non-unicast services to operate across a logical point-to-point tunnel.
RFC 2784 defines GRE as a general mechanism for encapsulating an arbitrary network-layer protocol over another network-layer protocol. It also defines the Protocol Type field used to identify the carried payload.
Huawei uses GRE as an SD-WAN overlay data-channel option and can additionally secure it using IPsec when confidentiality and integrity are required.
