Huawei HCIA-Datacom V2.0 認定 H12-811_V2.0 試験問題 (Q28-Q33):

質問 # 28
R1 has the following configurations:
[R1] nat address-group test 1
[R1-address-group-test] section 1 100.1.23.1 100.1.23.254
[R1-address-group-test] mode pat
[R1-address-group-test] quit
[R1] nat-policy
[R1-policy-nat] rule name test
[R1-policy-nat-rule-test] source-address range 192.168.0.0 192.168.255.255
[R1-policy-nat-rule-test] action source-nat address-group test
[R1-policy-nat-rule-test] quit
[R1-policy-nat] quit
[R1] interface GE 0/0/2
[R1-GE0/0/2] nat enable
[R1-GE0/0/2] quit
Which of the following statements is false ?

正解：A

解説：
Option C is false. In this configuration, the NAT address group test contains the public address range
100.1.23.1 to 100.1.23.254 , and the address group works in PAT mode . Port Address Translation allows multiple different intranet users to share the same public IP address while being distinguished by different transport-layer port numbers. Therefore, intranet users with different private IP addresses do not have to use different post-NAT public IP addresses.
Option A is true because 100.1.23.254 is included in the configured public address pool and can be used for source NAT. Option B is also true because NAT is enabled on GE0/0/2 , so if user traffic does not leave through that interface, the NAT policy may not be applied and public access may fail. Option D is true because the configured source address range includes 192.168.1.100, which falls within 192.168.0.0 to
192.168.255.255. HCIA-Datacom teaches that NAT behavior depends on matching traffic, address pools, PAT or no-PAT mode, and the interface where NAT is enabled. This question mainly tests understanding of source NAT and PAT address-sharing behavior.


質問 # 29
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)

正解：A、C、D

解説：
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.


質問 # 30
The following command output is displayed on R1:
[R1] display aaa configuration
Domain Name Delimiter : @
Domainname parse direction : Left to right
Domainname location : After-delimiter
Administrator user default domain : default_admin
Normal user default domain : default
Domain : total: 256 used: 3
Authentication-scheme : total: 32 used: 2
Accounting-scheme : total: 32 used: 1
Authorization-scheme : total: 32 used: 2
Service-scheme : total: 256 used: 0
Recording-scheme : total: 32 used: 0
Local-user : total: 512 used: 2
Remote-admin-user block retry-interval : 5 Min(s)
Remote-admin-user block retry-time : 3
Remote-admin-user block time : 5 Min(s)
Session timeout invalid enable : No
Which of the following statements is false?

正解：B

解説：
Comprehensive and Detailed 150 to 200 words of Explanation From Datacom knowledge:
The false statement is B . From the AAA configuration output, the value of Remote-admin-user block time is clearly shown as 5 Min(s) , which means the account lockout duration is 5 minutes , not 30 minutes.
Option A is true because Remote-admin-user block retry-time : 3 indicates that after 3 consecutive authentication failures , the account will be blocked. Option C is also true because the displayed Domain Name Delimiter is @ , which is the separator used in usernames such as [email protected]. Option D is true as well because the output shows Local-user : total: 512 used: 2 , meaning that the device supports a maximum of 512 local users , and currently 2 local users have been created.
This question checks the ability to correctly read AAA configuration output on Huawei devices. In HCIA- Datacom knowledge, it is important to distinguish between retry interval , retry count , and block time , because these values represent different security control parameters and are often confused during troubleshooting or configuration review.


質問 # 31
In the leader AP networking architecture, the leader AP functions as a WAC and uses the CAPWAP protocol to uniformly manage and configure Fit APs.

正解：A

解説：
This statement is true . In the leader AP networking architecture, one AP acts as the leader AP , taking on controller-like functions similar to those of a WAC for a small or medium-sized WLAN deployment. It can centrally manage other Fit APs and deliver unified wireless configurations such as SSIDs, security settings, and radio parameters. CAPWAP is used for management and control communication between the leader AP and the managed Fit APs.
This architecture is useful in scenarios where deploying a dedicated WAC is unnecessary or uneconomical, but centralized AP management is still desired. It provides a balance between simplicity and control and is commonly used in branch offices, small campuses, and similar environments. HCIA-Datacom explains leader AP networking as an intermediate solution between fully autonomous AP deployment and full WAC + Fit AP enterprise architecture. The key point is that the leader AP behaves as the management node for the other APs and enables unified configuration and control. Therefore, the statement correctly describes both the role of the leader AP and the use of CAPWAP in this architecture.


質問 # 32
During VLAN planning for a campus network, VLAN IDs for different service types must be allocated consecutively, without redundancy, to prevent omissions in future allocations.

正解：B

解説：
This statement is false . In campus network VLAN planning, VLAN IDs do not have to be allocated strictly consecutively without any gaps. In fact, leaving some reserved VLAN IDs is often a practical and recommended design approach. VLAN planning should focus on clarity, scalability, maintainability, and service separation , rather than on forcing all VLAN IDs to be contiguous.
For example, an administrator may reserve certain VLAN ranges for user access, voice services, management, wireless services, guest access, future expansion, or specific departments. Such structured planning makes later network expansion easier and reduces the risk of service conflicts or disruptive renumbering. HCIA- Datacom emphasizes that good campus network planning should consider current requirements and future growth. Consecutive allocation may look tidy at first, but it can actually reduce flexibility and make later additions more difficult. Therefore, the idea that VLAN IDs must be assigned consecutively without redundancy to avoid omissions is not a correct design principle. Reasonable reservation and categorized allocation are often more beneficial in real enterprise campus networks.
