1In an 802.11ax (Wi-Fi 6) deployment, OFDMA divides a 20 MHz channel into the smallest possible Resource Units (RUs). What is the smallest RU size defined by 802.11ax?

A.26-tone RU

B.52-tone RU

C.106-tone RU

D.242-tone RU

Explanation: 802.11ax defines five OFDMA Resource Unit sizes: 26-tone, 52-tone, 106-tone, 242-tone, 484-tone, and 996-tone. The 26-tone RU is the smallest, occupying roughly 2 MHz of bandwidth, and allows the AP to serve up to nine clients simultaneously on a 20 MHz channel.

2Which 802.11ax feature allows an AP to schedule when battery-powered clients wake to transmit, reducing IoT device power consumption?

A.BSS Coloring

B.Target Wake Time (TWT)

C.Spatial Reuse

D.Beamforming

Explanation: Target Wake Time (TWT) negotiates a wake schedule between the AP and client so the client can sleep until its scheduled service period. TWT is especially valuable for battery-powered IoT and mobile devices because it cuts the time the radio must remain active.

3A Huawei AirEngine 8760-X1-PRO AP advertises a maximum modulation of 1024-QAM. Which 802.11 standard introduced 1024-QAM?

A.802.11ac Wave 2

B.802.11ax

C.802.11n

D.802.11be

Explanation: 802.11ax (Wi-Fi 6) introduced 1024-QAM (10 bits per symbol), increasing peak per-spatial-stream rates by about 25% over 256-QAM at high SNR. 802.11be (Wi-Fi 7) later added 4096-QAM.

4Which 802.11be (Wi-Fi 7) feature allows a single client to simultaneously transmit on multiple bands (for example 5 GHz and 6 GHz) within one association?

A.Multi-Link Operation (MLO)

B.BSS Coloring

C.Channel Bonding

D.Aggregated MAC Protocol Data Unit (A-MPDU)

Explanation: Multi-Link Operation (MLO) is a 802.11be capability that lets a Multi-Link Device (MLD) bind 2.4/5/6 GHz radios into a single logical association so traffic can be load-balanced or duplicated across links for lower latency and higher throughput.

5Wi-Fi 6E expands Wi-Fi 6 into which radio band?

A.2.4 GHz

B.5 GHz

C.6 GHz

D.60 GHz

Explanation: Wi-Fi 6E extends 802.11ax operation into the 6 GHz band (5.925-7.125 GHz in much of the world), adding up to 1200 MHz of new spectrum and seven 160 MHz channels free of legacy 802.11a/n/ac devices.

6In a Huawei FIT AP architecture, which protocol carries both control and data plane traffic between the AP and the AC?

A.LWAPP

B.CAPWAP

C.GRE only

D.IPsec

Explanation: Huawei FIT APs use CAPWAP (RFC 5415/5416) over UDP. The control plane uses UDP 5246 with DTLS by default, and the data plane uses UDP 5247. Tunnel-forwarding mode encapsulates all client traffic to the AC inside CAPWAP.

7Which Huawei AC discovery method uses DHCP Option 43 to deliver the AC IP address to a FIT AP?

A.Static AC IP configured via console

B.Layer 2 broadcast discovery

C.DHCP-based dynamic discovery

D.DNS SRV-record discovery

Explanation: With DHCP-based discovery, the DHCP server returns Option 43 (Vendor Specific Information) carrying the AC IP list. The FIT AP parses Option 43 sub-option 3 in Huawei format and unicasts CAPWAP Discovery Request packets to those ACs.

8On a Huawei AC running V200R023, which CLI command displays the runtime CAPWAP tunnel state of all online APs?

A.display ap all

B.display capwap configuration

C.display station all

D.display radio all

Explanation: display ap all lists every registered AP with its AP ID, name, MAC, IP, AP type, and current State (such as nor for normal). It is the standard first command for verifying CAPWAP tunnel and AP onlining state.

9A Huawei AC6800V is configured with both wired source interface Vlanif100 and a loopback. Which is the recommended CAPWAP source interface for a multi-segment AP deployment?

A.The physical interface closest to the APs

B.A dedicated loopback interface

C.Vlanif1 (default management VLAN)

D.Whichever interface receives the first Discovery Request

Explanation: Best practice is to bind capwap source interface to a loopback. A loopback is always up and reachable from any routed path, so APs can re-establish CAPWAP tunnels even if a physical uplink fails or routing converges via a different interface.

10In Huawei AC + FIT AP tunnel forwarding mode, where is user-traffic VLAN 802.1Q tagging added?

A.At the AP, before CAPWAP encapsulation

B.On the AC, after CAPWAP decapsulation

C.On the access switch closest to the AP

D.On the egress core switch

Explanation: In tunnel forwarding mode the AP encapsulates the entire 802.11 MSDU into CAPWAP and sends it to the AC. The AC terminates CAPWAP, maps the user to the configured service VLAN, and adds the 802.1Q tag before forwarding to the wired network.
