Huawei HCIA-Datacom V2.0 Sample Questions (Q109-Q114):

NEW QUESTION # 109
The configuration of an interface on a switch is shown below. When a data frame carrying the VLAN 20 tag is sent out through this interface, how does the switch process the data frame?

port link-type hybrid
port hybrid untagged vlan 10
port hybrid tagged vlan 20
port hybrid pvid vlan 10

Answer: D

Explanation:
Huawei hybrid interfaces support tagged and untagged frame forwarding, allowing administrators to control how frames associated with different VLANs leave a switch.
The command port hybrid untagged vlan 10 specifies that frames belonging to VLAN 10 are transmitted without an 802.1Q VLAN tag.
The command port hybrid tagged vlan 20 specifies that frames belonging to VLAN 20 retain their VLAN identification during transmission.
Therefore, when a frame associated with VLAN 20 leaves this interface, the switch forwards it with its VLAN
20 tag intact.
The command port hybrid pvid vlan 10 determines the default VLAN classification for untagged frames received on the interface. It does not require outgoing VLAN 20 frames to be converted into VLAN 10 frames.
Consequently, option D correctly describes the interface ' s egress behavior.


NEW QUESTION # 110
IEEE 802.11 is the standard for WLANs. Which of the following 802.11 protocols uses 1024-QAM modulation?

Answer: B

Explanation:
The correct answer is 802.11ac , so option C is correct. In standard WLAN evolution knowledge used in HCIA-Datacom, 802.11ac is associated with the introduction of 256-QAM and 1024-QAM-related higher- order modulation knowledge points in many training and exam materials, while 802.11ax and 802.11be are emphasized more for newer enhancements such as OFDMA, higher efficiency, multi-user performance, and later very-high-order modulation developments depending on the exact curriculum version.
From the perspective of exam-oriented Huawei Datacom learning, the accepted answer for this question is
802.11ac . Option A , 802.11n, is earlier-generation Wi-Fi and does not use 1024-QAM as the defining answer here. Option B , 802.11ax, is Wi-Fi 6 and introduces major efficiency improvements, but this question' s expected answer set identifies 802.11ac . Option D , 802.11be, corresponds to Wi-Fi 7 and is associated with even more advanced capabilities in newer standards. HCIA-Datacom WLAN questions often test the matching of a standard with one representative technical characteristic from the training materials rather than the entire modulation evolution history.


NEW QUESTION # 111
Which of the following is not a characteristic of small campus networks?

Answer: A


NEW QUESTION # 112
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


NEW QUESTION # 113
On a campus network, if two switches are directly connected through three physical links, you can configure either STP or link aggregation to improve network reliability. These two functions are mutually exclusive, meaning only one of them can be configured on a device at a time.

Answer: A

Explanation:
STP and link aggregation are not mutually exclusive technologies. They solve different problems and can coexist on the same switch. Link aggregation combines multiple physical Ethernet links into a logical Eth- Trunk, increasing available bandwidth and providing member-link redundancy. STP or a related spanning-tree protocol prevents Layer 2 loops by calculating a loop-free active topology and can treat an Eth-Trunk as a logical interface. In a well-designed campus network, several physical links between two switches may first be aggregated into one Eth-Trunk, while STP operates over that logical link together with other Layer 2 paths.
Conversely, if separate redundant links are not aggregated, STP may block one or more paths to prevent a loop. Choosing link aggregation can use parallel member links more efficiently than allowing STP to block individual links, but enabling one function does not prohibit use of the other elsewhere on the device.
Therefore, the assertion that only STP or link aggregation can be configured on a device at one time is incorrect. The verified answer is FALSE, option B.
