Which of the following statements is TRUE about AirEngine products?
Correct Answer:
B
Huawei'sAirEngineseries includes a range of Wi-Fi 6 APs with varying capabilities: AirEngine 5762-12:Supports a maximum device rate of2.975 Gbps, not 1.775 Gbps, making option A incorrect.
AirEngine 6761-21:Supports a maximum device rate of3.55 Gbps, making option B correct. AirEngine 5762-12SW:Does support the leader AP feature, making option C incorrect. AirEngine 5761-11:Does not have 2.5GE ports, making option D incorrect.
TheAirEngine 6761-21stands out for its high performance, making it suitable for demanding environments like large enterprises and campuses.

Which of the following statements are TRUE about iMaster NCE in terms of management and control?
Correct Answer:
AB
HuaweiiMaster NCEis acentralized network management and control systemforSDN-capableandtraditionaldevices.
(A) True – SDN control via NETCONF/YANG:iMaster NCE usesNETCONF(based on theYANG model) to manage and controlSDN-enableddevices, automating configuration and policy enforcement.
(B) True – SNMP for traditional devices:Traditional network devices (non-SDN) are managed throughSNMP (Simple Network Management Protocol), which provides device
monitoring and basic configuration.
(C) False – No direct control through CU (Control Unit):Huawei does not define aCUas an independent management entity in iMaster NCE. Instead, SDN-capable devices are controlled viaNETCONF/YANG, while traditional devices rely onSNMP.

Which option is the product having a wired side and a wireless side? On the wired side, APs connect to the campus network using Ethernet. On the wireless side, APs connect to downstream wireless terminals using the 802.11 protocol.
Correct Answer:
C
AWLAN (Wireless Local Area Network)is anetwork that connects wireless devices (Wi-Fi terminals) via access points (APs)using the802.11 protocol.
(A) LAN – False:A LAN is a broader concept that includes both wired and wireless networks.
(B) WAN – False:A WAN connects geographically distant networks, not local wireless devices.
(C) WLAN – True:APs connect to the wired network via Ethernet and provide wireless connectivity to devices.
(D) MAN – False:A MAN (Metropolitan Area Network) spans a city or large area, not limited to wireless connectivity.

The address that functions at the data link layer is called an IP address. Each network adapter that complies with the IEEE 802 standard must have an IP address.
Correct Answer:
B
The statement is incorrect because IP addresses function at the network layer (Layer 3) of the OSI model, not the data link layer (Layer 2). At the data link layer, devices useMAC addresses(Media Access Control addresses) to identify each other. MAC addresses are unique identifiers assigned to network adapters and are defined by the IEEE 802 standard.While IP addresses are essential for routing data across networks, they are not directly related to the data link layer. Therefore, the claim that "the address that functions at the data link layer is called an IP address" is false.

SRv6 can traverse all types of private lines for traffic optimization. Huawei NetEngine AR821 E can support SRv6.
Correct Answer:
A
Understanding SRv6 Capabilities:
SRv6 (Segment Routing over IPv6) is a next-generation networking technology that enables flexible traffic engineering and seamless traversal across different types of private lines.
Huawei NetEngine AR821 E Support for SRv6:
TheNetEngine AR821 Erouter supports SRv6, making it suitable for SD-WAN andWAN deployments where traffic optimization and path control are critical.
Conclusion:The statement is TRUE because SRv6 can traverse all types of private lines, and the NetEngine AR821 E supports SRv6.
