Huawei HCIA-Datacom V2.0 Sample Questions (Q26-Q31):

NEW QUESTION # 26
R1 has two equal-cost routes to 10.0.12.0/24 after the following commands are configured.
[R1] ip route-static 10.0.12.0 24 10.0.12.2 preference 60
[R1] ip route-static 10.0.12.0 24 10.0.21.2 preference 60

Answer: B

Explanation:
The source key marks this statement TRUE, but the topology makes that answer technically incorrect. R1 is shown with interface address 10.0.12.1/24, which automatically installs a directly connected route to 10.0.12.0
/24. On Huawei VRP, a direct route has preference 0, whereas a static route has preference 60 unless another value is configured. The two commands do configure two static routes with the same preference, and equal- preference static routes can support load balancing when they are the best routes to a destination. Here, however, both static routes are for the same prefix that R1 already owns as a connected network. The direct route has a higher priority because its preference value is smaller, so it is selected in the active IP routing table instead of the two preference-60 static routes. Therefore the assertion that R1 has two active equal-cost routes to 10.0.12.0/24 is FALSE as the question and exhibit are written. The verified answer is B, and the original source key A should be corrected.


NEW QUESTION # 27
Which of the following phases are required for establishing a connection between an SSH server and an SSH client? (Select all that apply)

Answer: A,B,C,D

Explanation:
The establishment of an SSH connection includes multiple mandatory phases that ensure both secure communication and authenticated access. First, the SSH client and server perform version negotiation to determine a mutually supported SSH protocol version. Then they carry out algorithm negotiation, during which they agree on the encryption algorithm, key exchange algorithm, integrity algorithm, and other security parameters to be used for the session.
After that, the peers perform key exchange, which is used to derive shared session keys securely over an insecure network. This stage is essential because it enables subsequent communication to be encrypted and protected against interception. Finally, once the secure channel has been established, user authentication is performed so that the server can verify the identity of the client user. This can be done using a password, public key, or other supported authentication method.
Therefore, all four options are required phases in the SSH connection establishment process.
HCIA-Datacom emphasizes these steps because SSH is a core secure management protocol used to replace insecure protocols such as Telnet and FTP in modern network operation and maintenance.


NEW QUESTION # 28
On the campus network shown in the figure below, the core switch Core1 functions as a Layer 3 gateway and as a DHCP server to dynamically assign IP addresses to AP1, PC1, PC2, and PC3.
The network below Core1 is a Layer 2 network. WAC1 and R1 are connected to Core1 at Layer
3. AP1 goes online through VLAN 100. The wireless service VLAN is VLAN 101, and the wired service VLANs for PC2 and PC3 are VLAN 102 and VLAN 103, respectively. Additionally, the direct forwarding mode is used for wireless traffic forwarding. If no additional VLANs are allowed on device interfaces, which of the following VLANs must be allowed on GE1/0/1 of ACC1? (Select all that apply)

Answer: A,C,D

Explanation:
According to the original topology and service-planning question, the required VLANs are VLAN
100, VLAN 101, and VLAN 102, so options A, B, and C are correct. In HCIA-Datacom campus design questions, VLAN planning is usually based on service separation, such as user services, voice services, wireless services, management services, or specific departmental segmentation.
Each service type is assigned an appropriate VLAN so that broadcast domains are separated and policies can be applied more effectively.


NEW QUESTION # 29
On the network shown in the figure, the administrator creates Eth-Trunk 1 in manual mode on SW1 and SW2, adds GE1/0/1 and GE1/0/2 on both switches to the Eth-Trunk 1, and sets the traffic forwarding mode to per- packet load balancing. However, the administrator finds that traffic from VLAN 10 cannot be forwarded, while traffic from VLAN 20 can be forwarded normally. The administrator verifies that the configuration of SW1 is correct. Which of the following statements are false about this fault scenario? (Select all that apply)

Answer: B,C,D

Explanation:
An Eth-Trunk combines multiple physical interfaces into one logical interface. VLAN permissions are configured on the logical Eth-Trunk rather than independently on individual member interfaces.
Option B describes a possible cause because SW2 may not permit VLAN 10 on Eth-Trunk 1, even though VLAN 20 is permitted.
Option A does not adequately explain the VLAN-specific failure. A failed member link would affect traffic distribution across the aggregated connection rather than inherently block only VLAN 10.
Option C is also inconsistent with normal VLAN 20 forwarding because incompatible aggregation modes could prevent the logical connection from operating correctly.
Option D is false because Eth-Trunk member interfaces do not independently control VLAN forwarding permissions.
Therefore, A, C, and D are the false explanations of the described fault.


NEW QUESTION # 30
The figure shows the process of a DHCP client obtaining an IP address from a DHCP server for the first time.
Match the following DHCP message types with the corresponding numbered stages shown in the figure.

Answer:

Explanation:

Explanation:
B, A, D, C
The HCIA-Datacom V2.0 Training Material explains that DHCP clients obtain IP addresses through four stages: Discovery, Offer, Request, and Acknowledgment.
In stage 1, the client broadcasts a DHCP DISCOVER message to locate available DHCP servers because it does not yet know the server ' s IP address.
In stage 2, a DHCP server responds with a DHCP OFFER containing an available IP address and other configuration parameters.
In stage 3, the client broadcasts a DHCP REQUEST to indicate the selected server and requested address.
Finally, in stage 4, the selected server sends a DHCP ACK confirming the allocation.
This four-stage process is commonly called DORA: Discover, Offer, Request, and Acknowledge.
