Huawei HCIA-Datacom V2.0 H12-811_V2.0 Prüfungsfragen mit Lösungen (Q33-Q38):

33. Frage
Which of the following hosts are reachable to the host at 192.168.1.200/27 at Layer 2? (Select all that apply)

A. 192.168.1.222/27
B. 192.168.1.192/27
C. 192.168.1.193/27
D. 192.168.1.221/27

Antwort: A,C,D

Begründung:
A /27 subnet mask is 255.255.255.224, which means each subnet contains 32 IP addresses. The subnet increments in blocks of 32 in the last octet: 0, 32, 64, 96, 128, 160, 192, 224. The address 192.168.1.200/27 belongs to the subnet 192.168.1.192/27.
For this subnet, the network address is 192.168.1.192, the broadcast address is 192.168.1.223, and the valid host range is from 192.168.1.193 to 192.168.1.222. Therefore, 192.168.1.221/27, 192.168.1.193/27, and
192.168.1.222/27 are all valid host addresses in the same subnet and are reachable at Layer 2 without routing.
That makes A, C, and D correct.
Option B is not correct because 192.168.1.192/27 is the network address of the subnet and cannot be assigned to a host by default. This question checks IP subnetting and the ability to identify valid hosts within the same broadcast domain.

34. Frage
The essence of communication is the transmission and exchange of information between two or more points.
The three elements of communication are the sender, content, and transmission channel of the information.
The receiver of the information is not included among these elements.

A. TRUE
B. FALSE

Antwort: B

Begründung:
This statement is false because the receiver is one of the fundamental elements of communication. In basic communication theory, a complete communication process requires at least four essential elements: the sender
, the information or message content , the transmission medium or channel , and the receiver . If the receiver is missing, communication cannot be completed because there is no endpoint to accept, interpret, or respond to the transmitted information.
In datacom networks, this concept maps directly to real networking scenarios. A source host generates data, the data is carried over some medium such as copper, fiber, or wireless, and a destination host receives the data. Network devices such as switches and routers assist the forwarding process, but the fundamental communication model still includes both communicating endpoints. HCIA-Datacom emphasizes the complete sender-to-receiver process when introducing network communication basics, protocol encapsulation, and forwarding. Therefore, excluding the receiver from the communication elements is conceptually incorrect.
The correct understanding is that sender, receiver, information content, and channel together form the essential basis of communication.

35. Frage
Secure Shell (SSH) is a protocol that uses encryption and authentication mechanisms to implement network services, such as secure access and file transfer, securely over an insecure network. Which of the following protocols use SSH? (Select all that apply)

A. SFTP
B. DNS
C. STelnet
D. NETCONF

Antwort: A,C,D

Begründung:
Several upper-layer management and file transfer protocols use SSH as their secure transport foundation.
SFTP is the SSH File Transfer Protocol and operates over SSH, making option C correct. STelnet is secure Telnet implemented over SSH, so option D is also correct. NETCONF commonly uses SSH as its transport protocol for secure configuration management and device orchestration, making option B correct as well.
Option A, DNS, does not use SSH as its normal transport protocol. Traditional DNS operates over UDP or TCP port 53, depending on the query or transfer type. Although DNS security extensions and encrypted DNS variants exist, they are not based on SSH. HCIA-Datacom emphasizes the role of SSH in secure network management because it replaces insecure plaintext protocols and provides confidentiality, integrity, and authentication. In practical Huawei enterprise deployments, SSH-based protocols are widely used for interactive device login, automated configuration delivery, and secure file operations. This question tests recognition of management protocols that inherit SSH's secure channel rather than protocols that operate independently at the application layer.

36. Frage
Both SNMP Trap and Inform Request are used by managed devices to send alarms to the NMS. Inform Request requires an acknowledgment from the NMS, whereas Trap does not.

A. FALSE
B. TRUE

Antwort: B

Begründung:
This statement is true . In SNMP, both Trap and Inform messages are used by managed devices to proactively report alarms or events to the Network Management System (NMS) . However, their reliability behavior is different. A Trap is sent without requiring an acknowledgment from the NMS. Once it is transmitted, the sender does not confirm whether the manager actually received it.
By contrast, an Inform Request requires the NMS to send a response confirming receipt. If the managed device does not receive the acknowledgment within the expected time, it can retransmit the Inform message.
Because of this, Inform is considered more reliable than Trap, although it also introduces slightly more overhead. HCIA-Datacom highlights this difference when explaining SNMP-based monitoring and alarm reporting. In real network O & M scenarios, the choice between Trap and Inform depends on the required balance between reliability and simplicity. This question tests a very standard SNMP knowledge point: Trap is unacknowledged , while Inform is acknowledged . Understanding this distinction helps network engineers choose suitable alarm reporting mechanisms in enterprise monitoring platforms.

37. Frage
Which of the following IP addresses cannot be configured for a host by default?

A. 172.16.1.1/16
B. 10.0.0.1/8
C. 192.168.1.1/24
D. 224.0.0.1/24

Antwort: D

Begründung:
The address 224.0.0.1/24 cannot be configured as a normal host IP address by default because it belongs to the Class D multicast address range . IPv4 multicast addresses range from 224.0.0.0 to 239.255.255.255 and are reserved for multicast group communication rather than assignment to host interfaces as ordinary unicast addresses. Therefore, option D is correct.
The other three options are all private unicast address ranges and can be configured on hosts in private networks. 10.0.0.1/8 belongs to the 10.0.0.0/8 private range, 172.16.1.1/16 belongs to the 172.16.0.0/12 private range, and 192.168.1.1/24 belongs to the 192.168.0.0/16 private range. These are commonly used in enterprise and campus networks. HCIA-Datacom teaches that host IP address planning must distinguish between unicast, multicast, loopback, broadcast, and other special-purpose ranges. Multicast addresses identify multicast groups and are processed differently by hosts and network devices, so they are not valid default host addresses for ordinary end-to-end IP communication.
