Huawei HCIA-Datacom V2.0 Sample Questions (Q22-Q27):

NEW QUESTION # 22
Which of the following port states are included in Rapid Spanning Tree Protocol (RSTP)?

Answer: A,C,D

Explanation:
RSTP (Rapid Spanning Tree Protocol) combines the Blocking, Listening, and Disabled states into Discarding, reducing the number of states to Discarding, Learning, and Forwarding. RSTP does not use a separate Listening state, as in standard STP.


NEW QUESTION # 23
In IPv4, the Options field can extend the header length from 20 bytes up to 60 bytes. To provide support for more options, IPv6 introduces the concept of extension headers. This design allows new options to be added without altering the existing header structure, demonstrating excellent flexibility.

Answer: A

Explanation:
IPv6 was designed to improve flexibility compared to IPv4 by removing the variable-length options field from the base header and introducing extension headers instead. This allows new features and options to be added in a modular way without changing the fixed IPv6 header structure, making the protocol more extensible and efficient.


NEW QUESTION # 24
Which of the following is the default value of the Router Dead Interval field in OSPF Hello packets on a broadcast network?

Answer: D

Explanation:
The default Router Dead Interval in OSPF is 40 seconds for broadcast and point-to-point networks. This interval defines the time period a router waits to receive hello packets before declaring a neighbor as down.


NEW QUESTION # 25
Drag and Drop Question
On the switched network shown in the figure, STP is enabled on all devices. SW1 is the root bridge. The port costs are shown in the figure. Other parameters retain the default values. Match the port roles after the network is stable with the ports. (Token is reusable)

Answer:

Explanation:

Explanation:
Designated port: GE1/0/1 of SW1, GE1/0/2 of SW1, GE1/0/3 of SW2
Root port: GE1/0/1 of SW2, GE1/0/3 of SW3
Alternate port: GE1/0/2 of SW3
SW1 is the root bridge, so all its active interfaces toward other switches operate as designated ports. Each non-root switch selects its root port based on the lowest total path cost to SW1: SW2 prefers the direct link to SW1, while SW3 prefers the path via SW2 because it has a lower cumulative cost than its direct link to SW1. On the SW2-SW3 segment, the switch with the lower path cost to the root becomes the designated port, while the other side becomes an alternate (blocked) port to prevent loops.


NEW QUESTION # 26
During WLAN deployment, a Fit AP fails to go online on the WAC. You log in to the WAC and run the display ap online-fail-record command to locate the fault. The command output shows that the cause is Insufficient license resources . This means that the license resources on the WAC are insufficient and that you need to expand the license capacity.

Answer: A

Explanation:
This statement is true . On a Huawei WAC, the number of APs that can go online is controlled by the available license resources . If a Fit AP fails to come online and the command display ap online-fail-record shows Insufficient license resources , it means the controller does not currently have enough licensed capacity to allow additional APs to register successfully.
In this case, the administrator must expand the license capacity or adjust existing license allocation so that the AP can be admitted. This is a common WLAN deployment issue, especially when new APs are added without first verifying the current AP license limit on the WAC. HCIA-Datacom troubleshooting methodology emphasizes interpreting controller diagnostics and fault records accurately. An AP can fail to go online for many reasons, including CAPWAP reachability problems, version mismatch, authentication issues, or licensing limitations. When the failure reason explicitly indicates insufficient license resources, the troubleshooting direction is clear: the controller's AP license capacity must be checked and, if necessary, increased. This question tests the ability to map a specific WAC alarm record to the correct operational response.


NEW QUESTION # 27
