1Which IEEE 802.11 amendment is commonly marketed as Wi-Fi 6?
A.802.11ac
B.802.11n
C.802.11ax
D.802.11be
Explanation: 802.11ax is the IEEE amendment branded as Wi-Fi 6 (and Wi-Fi 6E when extended into the 6 GHz band). It introduces OFDMA, uplink and downlink MU-MIMO, 1024-QAM, and BSS coloring to improve performance in dense environments.
2Which two frequency bands were the original WLAN bands defined for IEEE 802.11 before the 6 GHz extension?
A.900 MHz and 2.4 GHz
B.2.4 GHz and 5 GHz
C.5 GHz and 6 GHz
D.2.4 GHz and 60 GHz
Explanation: Mainstream Wi-Fi prior to Wi-Fi 6E used the 2.4 GHz ISM band and the 5 GHz UNII bands. 6 GHz was added later for Wi-Fi 6E and Wi-Fi 7 operation.
3In North America, which three 2.4 GHz channels are typically used together because they do not overlap when 20 MHz channel widths are deployed?
A.1, 5, 9
B.1, 6, 11
C.2, 7, 12
D.3, 8, 13
Explanation: With 20 MHz channels in the 2.4 GHz band, channels 1, 6, and 11 are the standard non-overlapping set used in North America. Co-channel reuse with this triple minimizes adjacent-channel interference.
4What does the unit dBm represent in WLAN RF measurements?
A.Power referenced to 1 milliwatt
B.Antenna gain referenced to an isotropic radiator
C.Signal-to-noise ratio in decibels
D.Free space path loss
Explanation: dBm expresses absolute power on a logarithmic scale referenced to 1 milliwatt. 0 dBm equals 1 mW, +20 dBm equals 100 mW, and -30 dBm equals 1 microwatt.
5A Huawei AP transmits at 17 dBm and uses an antenna with a gain of 5 dBi. Ignoring cable loss, what is the EIRP?
A.12 dBm
B.22 dBm
C.85 dBm
D.17 dBm
Explanation: Equivalent Isotropically Radiated Power (EIRP) equals transmit power plus antenna gain minus cable loss. 17 dBm + 5 dBi - 0 dB = 22 dBm.
6Which three Huawei AP working modes are commonly described in HCIA-WLAN materials?
A.Fat AP, Fit AP, and Cloud AP
B.Master AP, Slave AP, and Mesh AP
C.Bridge AP, Switch AP, and Router AP
D.Indoor AP, Outdoor AP, and Backbone AP
Explanation: Huawei classifies APs by working mode as Fat AP (autonomous), Fit AP (centrally managed by an AC over CAPWAP), and Cloud AP (managed by iMaster NCE-Campus or eSight cloud).
7Which protocol is used between a Huawei AC and Fit APs to carry control and management traffic?
A.LWAPP
B.CAPWAP
C.GRE
D.SNMP
Explanation: CAPWAP (Control And Provisioning of Wireless Access Points) is the IETF protocol used between an Access Controller and Fit APs. Huawei ACs use CAPWAP to provision, configure, and manage Fit APs.
8In a Huawei CAPWAP deployment, which security protocol is used to encrypt the CAPWAP control tunnel by default?
A.IPsec
B.DTLS
C.TLS
D.SSH
Explanation: CAPWAP encrypts the control tunnel using DTLS (Datagram Transport Layer Security). The data tunnel may be left unencrypted or encrypted with DTLS depending on configuration.
9Which UDP port does CAPWAP use for the control channel between an AC and an AP?
A.5246
B.5247
C.443
D.1812
Explanation: CAPWAP uses UDP port 5246 for the control channel and UDP port 5247 for the data channel, as defined in RFC 5415.
10Which of the following is the medium access method used by 802.11 stations to share the wireless channel?
A.CSMA/CD
B.CSMA/CA
C.Token passing
D.TDMA
Explanation: 802.11 uses Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) under the Distributed Coordination Function (DCF). Stations sense the medium and use random backoff to avoid collisions because collisions cannot be reliably detected on a wireless channel.
