NEW QUESTION # 10
Which of the following wireless security standards was proposed by China?
Answer: B
Explanation:
WAPI, or WLAN Authentication and Privacy Infrastructure, is the wireless LAN security standard proposed by China. It provides wireless link authentication and data-protection mechanisms and was developed as an alternative security framework for WLAN environments. Huawei's training material explicitly identifies WAPI as a WLAN security standard proposed in China and states that it provides stronger protection than legacy WEP and WPA mechanisms.
WPA, WPA2, and WPA3 belong to the Wi-Fi Protected Access family maintained through Wi-Fi industry certification. WPA was introduced as an interim improvement over WEP. WPA2 adopted stronger IEEE
802.11i security mechanisms, including AES-based CCMP. WPA3 later introduced stronger password- authentication and enterprise-security options.
WAPI incorporates authentication and encryption as part of an integrated wireless security architecture. Its deployment depends on regional requirements, terminal compatibility, AP support, and the organization's regulatory or cryptographic-policy obligations. The question asks which standard originated as a Chinese wireless security standard, not which standard is most widely deployed internationally. Therefore, WAPI is the only correct choice, making option B the verified answer.
NEW QUESTION # 11
Which of the following Wi-Fi 7 APs offers PCIe card-based IoT functions?
Answer: B
Explanation:
The AirEngine 6776I-X6TH is the model designed to provide PCIe card-based IoT expansion. The PCIe interface enables an appropriate IoT expansion card to be installed so that the AP can support additional wireless or sensing technologies according to the deployment requirement. This allows the same physical access infrastructure to deliver enterprise Wi-Fi and IoT connectivity.
The capability is useful in retail, healthcare, education, manufacturing, and asset-management environments, where technologies such as Bluetooth, RFID, Zigbee, electronic shelf labels, location services, or specialized sensing systems may need to coexist with the WLAN. A modular card design is preferable when an organization requires selectable or upgradeable IoT functions rather than only fixed integrated capabilities.
Huawei's Wi-Fi and IoT convergence architecture reduces repeated cabling, separate power systems, and independently managed wireless networks. It enables an IoT-capable AP to provide the installation position, power, management connectivity, and uplink data channel required by IoT modules. Among the models listed, the AirEngine 6776I-X6TH is the PCIe card-based IoT model. Therefore, option A is correct.
NEW QUESTION # 12
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 # 13
Which of the following statements are true about traffic encryption on SD-WAN links?
Answer: B,C
Explanation:
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.
NEW QUESTION # 14
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.
