Huawei HCIA-Datacom V2.0 Sample Questions (Q139-Q144):

NEW QUESTION # 139
A small enterprise's switches do not support LACP. Therefore, the administrator manually binds two links between two switches into an Eth-Trunk. Which of the following statements are false about this scenario? (Choose all that apply.)

Answer: A,D

Explanation:
Manually configured Eth-Trunk (static aggregation) does not support dynamic link management features such as automatic link addition or load-based negotiation. If a link fails, it is simply removed from forwarding but not automatically replaced by another link, and the system does not dynamically add new active links.
Also, static Eth-Trunk operates in load-sharing mode, not active/standby mode, so both links forward traffic simultaneously under normal conditions.


NEW QUESTION # 140
Enterprise data center (DC) services are no longer carried by physical machines or provided only for internal users. Instead, cloud platforms integrate resources in a unified manner and provide services for external users.
Continuous service innovation requires the DC construction mode to evolve from single-DC to multi-site multi-DC.

Answer: A

Explanation:
The statement describes the broader evolution of enterprise data centers from isolated, hardware-centric facilities toward cloud-based resource pools and multi-site service architectures. Virtualization and cloud platforms decouple many applications from individual physical servers and allow compute, storage, and network resources to be centrally orchestrated and delivered to internal or external consumers. As service scale and continuity requirements increase, organizations may deploy multiple data centers across sites for disaster recovery, geographic access, capacity expansion, active-active services, or regulatory separation.
Network technologies such as VXLAN-based fabrics and data center interconnect mechanisms support this transition by extending or interconnecting services while maintaining segmentation and reachability policies.
The exact architecture depends on business requirements, but the direction described in the question-from a single data center toward multi-site, multi-data-center construction as services evolve-is consistent with Huawei Datacom data center design concepts. Therefore, the statement is TRUE and option A is the correct answer.


NEW QUESTION # 141
Before calling a class from a third-party library in Python code, you must import relevant modules using import or from... import statements.

Answer: B

Explanation:
In Python, importing modules is not strictly required before calling a class only in all cases. While standard practice is to use import or from...import to access classes from third-party libraries, Python can still reference classes indirectly (for example through dynamic imports, exec, or prior namespace exposure). Therefore, the statement that it is mandatory in all cases is incorrect.


NEW QUESTION # 142
When a Huawei network device functions as an FTP server, which of the following are possible causes of an FTP client failing to log in to the FTP server? (Select all that apply)

Answer: A,B,C,D

Explanation:
All four options are possible causes of FTP login failure, so the correct answer is A, B, C, and D.
Option A is correct because if the FTP server function is not enabled on the Huawei device, the device cannot provide FTP services and the client cannot log in. Option B is also correct because if the authorized directory is not specified for the FTP user, the user may not be able to complete login or access file services properly, depending on the FTP user configuration requirements.
Option C is correct because an FTP user account must be configured with the required username and password; otherwise, authentication cannot succeed. Option D is also correct because if the network between the FTP client and the device is unreachable, the client cannot establish the FTP connection at all.
In HCIA-Datacom troubleshooting, FTP login failure is usually checked from four aspects: service enablement, user configuration, permission or directory authorization, and network connectivity.
This question tests standard remote maintenance troubleshooting logic for file transfer services on Huawei network devices.


NEW QUESTION # 143
On the network shown in the figure, the three PCs belong to VLAN 2. When configuring interface- based VLAN assignment, the administrator only forgets to configure the PVID of GE1/0/1.
However, PC1 can still communicate with PC2 at Layer 2.

Answer: B

Explanation:
If GE1/0/1 does not have its PVID configured, it uses the default VLAN (typically VLAN 1). This means PC1's untagged traffic will be placed into VLAN 1 instead of VLAN 2, while PC2 is correctly in VLAN 2. Since they are in different VLANs, Layer 2 communication between PC1 and PC2 is not possible.
