NEW QUESTION # 41
Which of the following protocol data packets can be encapsulated in a VPN using GRE?
Answer: A,B,C,D
Explanation:
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.
NEW QUESTION # 42
Which of the following models supports IPS, antivirus, and URL filtering at the same time?
Answer: A
Explanation:
The AR5710-SE is the security-enhanced model that supports intrusion prevention, antivirus, and URL filtering concurrently. The "SE" variant is designed for branch scenarios requiring integrated routing and advanced security processing instead of only basic WAN connectivity and packet forwarding.
IPS examines network traffic for attack signatures and abnormal behavior and can block detected intrusions.
Antivirus inspection identifies malicious files or content using security-signature databases. URL filtering controls access to websites based on categories, reputation, or explicitly configured allowlists and blocklists.
Supporting all three functions simultaneously allows the AR5710-SE to operate as both an SD-WAN CPE and a secure branch egress gateway, reducing the requirement for an additional branch firewall.
Huawei's SD-WAN security architecture identifies firewall protection, antivirus, IPS, and URL filtering as its principal service-traffic security functions. Huawei also recommends advanced security functions such as URL filtering, IPS, and antivirus for branch scenarios requiring stronger Internet-egress protection. Among the listed models, the AR5710-SE provides the combined feature set. Therefore, option A is correct.
NEW QUESTION # 43
Which of the following can be determined through a survey of the terminal types on a customer's network?
Answer: A
Explanation:
A terminal-type survey primarily determines the appropriate network admission control solution. Different terminal categories have different authentication capabilities and security requirements. Corporate laptops may support 802.1X authentication, guests may require Portal authentication, and printers, cameras, sensors, and other dumb terminals commonly require MAC-address authentication or automatic terminal identification.
Huawei recommends selecting authentication technologies according to the terminal type and usage scenario.
For example, access switches can serve as authentication points for wired dumb terminals, while APs or other access devices can perform authentication for wireless users. After terminal identification is enabled, iMaster NCE-Campus can automatically assign VLANs, ACLs, security groups, QoS parameters, and other authorization policies according to terminal category.
The survey therefore establishes which endpoints support interactive authentication, which require non- interactive admission, and which must receive special isolation or compliance policies. It does not independently determine the complete physical network architecture or the overall O & M platform.
Consequently, the terminal survey is used to formulate the network admission control solution, making option C correct.
NEW QUESTION # 44
Which of the following capabilities were introduced with Wi-Fi 7?
Answer: B,D
Explanation:
The capabilities introduced with Wi-Fi 7 are 4096-QAM and channel bandwidth of up to 320 MHz. Wi-Fi 7, based on IEEE 802.11be Extremely High Throughput, doubles the maximum channel width available under Wi-Fi 6 and Wi-Fi 6E from 160 MHz to 320 MHz where sufficient regulatory spectrum is available. It also introduces 4096-QAM, encoding 12 bits per modulation symbol compared with 10 bits for Wi-Fi 6's 1024- QAM. This can increase peak spectral efficiency when the signal-to-noise ratio is sufficiently high.
The other options were available before Wi-Fi 7. Support for up to eight spatial streams existed in earlier IEEE 802.11 generations, and MU-MIMO was already supported before Wi-Fi 7, with major uplink and downlink enhancements delivered by Wi-Fi 6. The 6 GHz band was commercially introduced through Wi-Fi
6E. Huawei's material specifically describes Wi-Fi 6E as extending Wi-Fi 6 into the 6 GHz spectrum. Wi-Fi 7 continues using 6 GHz but did not introduce it. Therefore, only A and C are correct.
NEW QUESTION # 45
Which of the following are Target Wake Time (TWT) technologies?
Answer: B,C,D
Explanation:
Broadcast TWT, Individual TWT, and Implicit TWT are valid Target Wake Time concepts. Individual TWT establishes a wake schedule between an AP and a specific station. Broadcast TWT advertises scheduling information that multiple stations can use, reducing individual negotiation overhead and coordinating groups of devices. An implicit TWT agreement defines a repeating schedule in which subsequent wake times are calculated from the agreed wake interval instead of being renegotiated for every service period.
These mechanisms allow stations, particularly battery-powered IoT devices, to sleep for predictable periods and wake only when transmission or reception is scheduled. TWT consequently reduces power consumption, channel contention, collisions, and unnecessary medium access in dense WLAN environments. Research describing IEEE 802.11ax TWT confirms that the mechanism schedules station transmission periods and allows stations to remain asleep outside their negotiated service periods.
"Multicast TWT" is not one of the standard TWT concepts represented by this question. Broadcast scheduling can cover multiple stations, but that does not create a separate mechanism formally identified here as Multicast TWT. Therefore, the correct answers are A, B, and C.
