Huawei HCIA-Datacom V2.0 Sample Questions (Q105-Q110):

NEW QUESTION # 105
When a Huawei device functions as an SSH client to log in to another network device for the first time, the ssh client first-time enable command must be run to enable the first-time login function of the SSH client.
Otherwise, the login fails.

Answer: B

Explanation:
The HCIA-Datacom V2.0 Training Material describes the configuration of Huawei devices operating as SSH clients.
For the first-time-login workflow, the command ssh client first-time enable enables the SSH client to establish its initial connection with an SSH server whose host public key has not already been trusted.
SSH provides authentication, encryption, and integrity protection to secure remote management traffic.
During initial connection establishment, the SSH client must handle the server ' s host public key to establish trust.
The first-time-login function permits this initial trust-establishment process. Without it, a connection to a server whose host key has not been provisioned may fail.
The training material explicitly includes this command in its SSH client configuration procedure.
Therefore, within the first-time-login configuration scenario described in the question, the statement is TRUE.


NEW QUESTION # 106
When Telnet or the web system is used to manage a device, which of the following mechanisms can be deployed to allow only fixed user IP addresses to log in to the device?

Answer: A

Explanation:
An Access Control List (ACL) can filter packets based on specified matching conditions, including source and destination IP addresses.
Huawei ' s HCIA-Datacom training material explains that ACLs provide traffic classification and access- control capabilities.
To restrict remote management access, an administrator can configure ACL rules that permit connections originating from authorized management IP addresses and deny connections from other sources.
The ACL must be applied to the appropriate management service or user interface for the restrictions to take effect.
Option A is incorrect because telemetry is primarily used for collecting and reporting operational data.
Option C is incorrect because SNMP is designed for network monitoring and management rather than implementing the specified login-source filtering mechanism.
Option D provides authentication, authorization, and accounting, but it is not the direct mechanism requested for filtering specific source IP addresses.
Therefore, option B is correct.


NEW QUESTION # 107
Huawei network devices support multiple types of storage devices. After the administrator enters the save command in the user view of a switch, the current configuration file is saved to the SDRAM. After the switch restarts, the configuration file still takes effect.

Answer: B

Explanation:
On Huawei switches, the active configuration is stored in SDRAM during operation, but SDRAM is volatile memory. The save command writes the configuration to non-volatile storage (such as NVRAM/flash), not to SDRAM. This is what allows the configuration to persist after a restart.


NEW QUESTION # 108
NAPT and Easy IP translate both IP addresses and port numbers to allow multiple private IP addresses to share multiple public IP addresses.

Answer: B

Explanation:
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.


NEW QUESTION # 109
On the network shown in the figure, R1 and R2 are directly connected through a physical link.
When the link is normal, R1 can ping the IP address of R2's interface.

Answer: B

Explanation:
Although R1 and R2 are directly connected and belong to the same subnet (10.0.12.0/24 vs
10.0.21.0/24), they are actually in different IP networks. R1's interface is in 10.0.12.0/24 while R2's interface is in 10.0.21.0/24, which are not the same subnet, so they cannot communicate directly at Layer 3 without routing. Therefore, R1 cannot successfully ping R2's interface IP under normal conditions.
