Huawei HCIA-Datacom V2.0 Sample Questions (Q42-Q47):

NEW QUESTION # 42
On the network shown in the figure, GE1/0/1 and GE1/0/2 of SW1 are access interfaces, and their PVIDs are VLAN 2 and VLAN 3 respectively. GE1/0/1 of SW2 is also an access interface, and its PVID is VLAN 4.
Which of the following configurations on SW1 and SW2 can ensure that data packets sent from PC1 and PC2 can reach PC3?

Answer: B,C

Explanation:
PC1 and PC2 are in different VLANs on SW1, while PC3 is in VLAN 4 on SW2. To allow traffic from VLAN 2 and VLAN 3 users to reach PC3 through the inter-switch link, SW1 must be able to send frames from PC1 and PC2 toward SW2 in a form that SW2 can place into VLAN 4.
Option B is valid because a hybrid interface on SW1 can send frames from VLAN 2 and VLAN 3 untagged, and setting the PVID to VLAN 4 allows untagged inbound frames on the peer side to be associated appropriately when matched with the SW2 configuration. Option C is also valid because configuring SW2's GE1/0/3 as a trunk allowing VLAN 4 and setting its PVID to VLAN 4 means untagged frames arriving from SW1 are treated as belonging to VLAN 4 and can then be forwarded to PC3 through its access interface.
Option A is incomplete because only configuring SW2 does not solve the VLAN handling on SW1. Option D is incorrect because a trunk on SW1 would send VLAN 2 and VLAN 3 frames tagged, which would not match the VLAN 4-only expectation on SW2 in this scenario.


NEW QUESTION # 43
The network administrator performs the configuration shown in the figure on SW1 and SW2.
Which of the following statements are false about this scenario? (Choose all that apply.)

Answer: A,B,D

Explanation:
PC1 is in VLAN 1 and PC2 is in VLAN 3 on SW1, so they are in different VLANs and cannot communicate at Layer 2.
PC1 and PC3 are both in VLAN 1, but VLAN 1 traffic is not allowed on the trunk link, so communication between switches for VLAN 1 traffic is blocked.
PC2 is in VLAN 3 while PC3 is in VLAN 1, so they are in different VLANs and cannot communicate at Layer 2.
PC2 and PC4 are both in VLAN 3, and VLAN 3 is permitted across the trunk, so they can communicate successfully.


NEW QUESTION # 44
The essence of communication is the transmission and exchange of information between two or more points.
The three elements of communication are the sender, content, and transmission channel of the information.
The receiver of the information is not included among these elements.

Answer: A

Explanation:
This statement is false because the receiver is one of the fundamental elements of communication. In basic communication theory, a complete communication process requires at least four essential elements: the sender, the information or message content, the transmission medium or channel, and the receiver. If the receiver is missing, communication cannot be completed because there is no endpoint to accept, interpret, or respond to the transmitted information.
In datacom networks, this concept maps directly to real networking scenarios. A source host generates data, the data is carried over some medium such as copper, fiber, or wireless, and a destination host receives the data. Network devices such as switches and routers assist the forwarding process, but the fundamental communication model still includes both communicating endpoints. HCIA-Datacom emphasizes the complete sender-to-receiver process when introducing network communication basics, protocol encapsulation, and forwarding. Therefore, excluding the receiver from the communication elements is conceptually incorrect.
The correct understanding is that sender, receiver, information content, and channel together form the essential basis of communication.


NEW QUESTION # 45
In the STP topology shown in the figure, all links have the same path cost, and SW1 is the root bridge. Which of the following ports will become designated ports? (Select all that apply)

Answer: B,C,D

Explanation:
In STP, the root bridge has all its active ports elected as designated ports on each connected segment. On non-root switches, one port is selected as the root port , and on each LAN segment, one designated port is elected based on the best BPDU. Since SW1 is the root bridge and all links have equal cost, the election depends first on the path cost to the root, then on bridge ID, and then on port ID if needed.
According to the topology, the ports that become designated are GE1/0/2 of SW2 , GE1/0/1 of SW2 , and GE1/0/3 of SW3 , which correspond to option A , B , and C . Option D is not a designated port in this topology because that segment has another port with a superior BPDU and therefore SW4's port does not win the designated-port election. HCIA-Datacom emphasizes that designated ports are elected per segment , not per switch, and that every non-root switch must compare received BPDUs to determine root and designated roles. This question tests the ability to apply STP election logic rather than simply memorizing port-role definitions.


NEW QUESTION # 46
When planning IPv4 addresses for a campus network, which of the following methods can you use to assign an IP address to the interface connecting the campus egress device to the WAN?
(Choose all that apply.)

Answer: A,B,C

Explanation:
For IPv4 WAN-facing interfaces in campus networks, valid address assignment methods include static configuration, DHCP-based dynamic allocation, and PPPoE for access authentication and address assignment in broadband scenarios. These are all standard IPv4 mechanisms for obtaining or configuring IP addresses on WAN interfaces.
SLAAC is an IPv6 stateless auto-configuration mechanism and is not used for IPv4 address assignment, so it is not applicable in this context.
