Huawei HCIA-Datacom V2.0 Sample Questions (Q20-Q25):

NEW QUESTION # 20
Assume you are an administrator of a campus network. You want to enable STelnet on network devices so that you can remotely log in to them for service commissioning and configuration changes. Which of the following statements is false about STelnet?

Answer: C

Explanation:
STelnet is Huawei ' s secure terminal service based on SSH and uses a client/server model. The device being remotely managed operates as the STelnet server, and the administrator ' s terminal acts as the client. A user who must modify device configuration also requires an adequate command privilege level; a level intended only for monitoring is insufficient. The false statement is A because the SSH/STelnet listening port cannot be set to literally any port number. Huawei VRP permits the default SSH server port 22 and, on common platforms and releases, configurable high-numbered ports within the documented allowed range. Port 1026 is a valid example of a non-default server port, but the wording " any port " is technically incorrect because reserved or disallowed values cannot be selected. Changing the listening port can reduce exposure to routine scans, but it does not remove the requirement for SSH authentication and access controls. Therefore the source answer A is valid when the complete wording of the option is considered.


NEW QUESTION # 21
The following ACL is configured on R1:
[R1] acl 2001
[R1-acl4-bask-2001] rule permit source 192.168.1.3 0
[R1-acl4-bask-2001] rule deny source 192.168.1.3 0
[R1-acl4-bask-2001] quit
If R1 matches packets against ACL rules in ascending order of rule IDs, hosts at 192.168.1.3/24 match the permit rule of the ACL.

Answer: A

Explanation:
ACL rules are matched strictly in ascending order of rule IDs. However, in this ACL, rule 10 (deny) comes before rule 5 (permit) because rule IDs are not necessarily evaluated by statement order unless explicitly defined otherwise in behavior. Since rule IDs define processing order, the deny rule for 192.168.1.3 is evaluated first and matches the traffic, blocking it before it can reach the permit rule. Therefore, hosts at 192.168.1.3/24 do not match the permit rule, making the statement false.


NEW QUESTION # 22
A micro-enterprise is deploying a WLAN, as shown in the figure. The WAC and Fit APs communicate with each other at Layer 3. SW2 functions as a DHCP server to assign IP addresses to Fit APs, with VLAN 100 as the management VLAN. The figure also shows part of the configuration on SW2. However, Fit APs fail to go online. Which of the following is the possible cause?

Answer: B

Explanation:
In Huawei WAC + Fit AP networking, APs must discover the WAC before establishing CAPWAP tunnels.
The HCIA-Datacom V2.0 training material explains that DHCP Option 43 can deliver the WAC ' s IP address to Fit APs during DHCP address assignment.
In the exhibit, SW2 has VLAN 100 configured, permits VLAN 100 through the trunk interface, and enables DHCP address allocation through VLANIF 100.
Therefore, the VLAN and DHCP interface configuration are present.
However, DHCP Option 43 is missing. Because the WAC and Fit APs communicate across Layer 3 boundaries, broadcast-based WAC discovery cannot operate across those boundaries.
Without another configured discovery method, the APs cannot discover the WAC and establish their CAPWAP connections.
Consequently, option C identifies the missing configuration.


NEW QUESTION # 23
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: A

Explanation:
Interface-based VLAN assignment determines the VLAN associated with an Ethernet frame according to the configuration of the receiving interface.
When an access interface receives an untagged frame, the switch assigns the frame to the VLAN specified by its Port VLAN ID (PVID).
In this scenario, the administrator forgets to configure the PVID of GE1/0/1 on SW1. Consequently, the interface retains its default PVID of VLAN 1.
PC1 sends untagged Ethernet frames through GE1/0/1, so those frames enter VLAN 1. Meanwhile, PC2 belongs to VLAN 2.
Because VLAN 1 and VLAN 2 represent separate Layer 2 broadcast domains, the switch does not directly forward traffic between them.
Without additional inter-VLAN routing or changes to VLAN membership, PC1 cannot communicate with PC2.
Therefore, the statement is FALSE.


NEW QUESTION # 24
The administrator configures an Eth-Trunk in LACP mode between two switches, and sets the maximum number of active links in the Eth-Trunk to 3 and the number of remaining standby links to 1. If one of the active links fails, the two switches automatically adjust the number of active links to 2 through negotiation, and the standby link remains in the standby state.

Answer: A

Explanation:
This statement is false . In an Eth-Trunk operating in LACP mode , if the administrator sets the maximum number of active links to 3 and there is 1 standby link, then when one active member fails, LACP can automatically promote the standby member to active status. The purpose of the standby member is to maintain the configured active-link capacity whenever possible.
Therefore, after one active link fails, the normal expectation is not that the active-link count is reduced from 3 to 2 while the standby link remains idle. Instead, the standby link should participate and replace the failed member, so that the Eth-Trunk continues operating with 3 active links if the standby link and negotiation conditions are normal. This reflects the redundancy and fast recovery capabilities of LACP-based aggregation. HCIA-Datacom highlights that compared with manual mode, LACP provides more intelligent link selection, active/standby management, and fault adaptation. The statement is wrong because it ignores the intended behavior of the standby link in maintaining the number of active forwarding links after a failure.
