Huawei HCIA-Datacom V2.0 H12-811_V2.0 Prüfungsfragen mit Lösungen (Q131-Q136):

131. Frage
IEEE 802.11 is the standard for WLANs. Which of the following 802.11 protocols uses 1024-QAM modulation?

Antwort: B

Begründung:
The correct answer is 802.11ac, so option C is correct. In standard WLAN evolution knowledge used in HCIA-Datacom, 802.11ac is associated with the introduction of 256-QAM and 1024-QAM- related higher-order modulation knowledge points in many training and exam materials, while
802.11ax and 802.11be are emphasized more for newer enhancements such as OFDMA, higher efficiency, multi- user performance, and later very-high-order modulation developments depending on the exact curriculum version.
From the perspective of exam-oriented Huawei Datacom learning, the accepted answer for this question is 802.11ac.


132. Frage
In a wireless communication system, information is first converted into digital signals for easy circuit calculation and processing by the transmitter through source coding, and then converted into radio waves through channel coding and modulation. Which of the following parameters of a carrier are modified during the modulation process based on signal changes? (Select all that apply)

Antwort: A,B,C

Begründung:
During modulation, the transmitter maps digital information onto certain physical characteristics of a carrier signal so that the information can be transmitted over the air. The three classic carrier parameters that can be modified are amplitude , frequency , and phase . Therefore, options A , B , and D are correct.
Amplitude modulation changes the strength of the carrier wave. Frequency modulation changes the oscillation rate of the carrier. Phase modulation changes the phase angle of the carrier relative to a reference. Modern wireless communication systems often combine these parameters, especially amplitude and phase, in complex digital modulation schemes such as QPSK, 16-QAM, 64-QAM, or higher-order QAM used in WLAN standards. Option C , channel, is not a carrier parameter modified during modulation. A channel refers to a frequency resource or spectrum allocation used for communication, not a physical waveform characteristic being directly altered to encode bits. HCIA-Datacom introduces these basic wireless concepts to help learners understand how WLAN signals are transmitted, how data rate improvements are achieved, and why different modulation methods have different requirements for signal quality and interference resistance.


133. Frage
When deploying a WLAN with the WAC + Fit AP architecture on a customer's live network, you find that APs fail to go online. Which of the following are possible causes? (Choose all that apply.)

Antwort: A,B,D

Begründung:
APs may fail to go online due to issues in IP address acquisition, control connectivity, or CAPWAP configuration. Incorrect DHCP settings can prevent APs from obtaining IP addresses, and an unavailable link between APs and WAC will block CAPWAP establishment. If no CAPWAP address is configured on the WAC, APs cannot discover or establish a control channel to the WAC. AP working mode being Fat is not a typical direct cause of online failure in a Fit AP + WAC deployment, since mode mismatch alone does not inherently block online status if properly converted or managed.


134. Frage
Which of the following port states are included in Rapid Spanning Tree Protocol (RSTP)?

Antwort: B,C,D

Begründung:
RSTP (Rapid Spanning Tree Protocol) combines the Blocking, Listening, and Disabled states into Discarding, reducing the number of states to Discarding, Learning, and Forwarding. RSTP does not use a separate Listening state, as in standard STP.


135. Frage
NAPT and Easy IP translate both IP addresses and port numbers to allow multiple private IP addresses to share multiple public IP addresses.

Antwort: A

Begründung:
NAPT and Easy IP both perform port-level translation in addition to IP address translation. This allows multiple private hosts to share one or more public IP addresses by differentiating sessions using port numbers, enabling efficient IPv4 address utilization.
