Huawei HCIA-Datacom V2.0 Sample Questions (Q130-Q135):

NEW QUESTION # 130
On an STP network, an administrator wants SW2 to be elected as the root bridge. Which of the following methods can be used to achieve this goal?

Answer: D

Explanation:
In STP, the root bridge is elected based on the lowest bridge ID (BID). A BID is composed of the bridge priority and the MAC address of the switch. The device with the smallest BID becomes the root bridge.
Therefore, if an administrator wants SW2 to become the root bridge, the most direct and correct method is to configure a lower system priority on SW2, making option C correct.
Option A is incorrect because port priority affects port-role selection in some tie-breaking scenarios, but it does not determine root-bridge election. Option B is the opposite of what is required, because a higher system priority makes the BID larger and reduces the chance of being elected as root. Option D is also incorrect because root path cost is used by non-root bridges to select the best path to the existing root bridge; it does not determine which switch becomes the root bridge in the first place. HCIA-Datacom stresses that bridge priority tuning is the standard administrative method used to control root bridge placement in campus networks for stable and predictable Layer 2 topology design.


NEW QUESTION # 131
You can enter a question mark (?) in the CLI of a Huawei switch to obtain online help. Which of the following statements is true about the meaning of < cr > in the output of the command sysname SW1?
[HUAWEI] sysname SW1?
< cr >

Answer: A

Explanation:
In the Huawei command-line interface, the question mark ? provides real-time command help based on the current input. When the output shows < cr > , it means that the command can end at that point by pressing Enter . In other words, there is no additional keyword or parameter required in that position. Therefore, option B is correct.
In the example sysname SW1?, the device interprets SW1 as a complete and valid hostname parameter for the sysname command. Since nothing else is required after the hostname, the CLI displays < cr > to indicate command completion is allowed. This behavior is common in Huawei devices and is important for daily operation and troubleshooting because it helps engineers understand whether a command is complete, whether more arguments are needed, or whether optional parameters are available. Options about incorrect keywords or incomplete commands do not apply here, because the entered command syntax is already valid.
Understanding < cr > is a basic but important CLI skill in HCIA-Datacom operations.

NEW QUESTION # 132
Assume that you cannot configure an IP address for GE1/0/1 on a Huawei switch. Which of the following commands can you run in the interface view to resolve this problem?

Answer: A

Explanation:
On Huawei switches, a physical Ethernet interface usually works as a Layer 2 switch port by default. A Layer
2 interface cannot be assigned an IP address directly. If an administrator wants to configure an IP address on such an interface, the interface must first be converted into a Layer 3 interface. The command used for this is undo portswitch, so option B is correct.
After this command is executed, the interface no longer behaves as a Layer 2 switching port and can then support Layer 3 features such as direct IP address configuration. Options A, C, and D are all Layer 2 port-type commands used to configure the interface as a trunk, access, or hybrid port. These commands do not solve the problem because they keep the interface operating at Layer 2. HCIA-Datacom emphasizes the difference between Layer 2 switching interfaces and Layer 3 routed interfaces on switches. Understanding when to use undo portswitch is important in campus network deployment, especially when configuring routed uplinks, management interfaces, or inter-device Layer 3 links on switches.


NEW QUESTION # 133
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: D

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 # 134
On a switched network, the administrator has completed the VLAN-related configuration shown in the figure on SW1. If the administrator runs the ping 192.168.1.2 command on PC1, the ping will fail.

Answer: A

Explanation:
Both switch ports shown in the exhibit are configured as trunk ports and VLAN 10 is permitted, but the configuration does not change the trunk PVID from its default value of VLAN 1. On Huawei switches, untagged frames received on a trunk interface are associated with the interface PVID. A normal PC sends untagged Ethernet frames, so traffic from both PC1 and PC2 is classified into VLAN 1. VLAN 1 is permitted on a trunk by default unless it is explicitly removed with an undo port trunk allow-pass vlan 1 command. As a result, the two PCs remain in the same Layer 2 broadcast domain through VLAN 1 and can exchange ARP and ICMP traffic. Merely adding VLAN 10 to the allowed VLAN list does not force untagged host traffic into VLAN 10. Therefore, the statement that pinging 192.168.1.2 from PC1 must fail is incorrect. The correct response is FALSE, option B.
