Huawei HCIA-Datacom V2.0 Sample Questions (Q30-Q35):

NEW QUESTION # 30
Which of the following is not a type of OSPF packets?

Answer: A

Explanation:
OSPF defines five protocol packet types: Hello, Database Description (DD), Link State Request (LSR), Link State Update (LSU), and Link State Acknowledgment (LSAck). A Link State Advertisement, or LSA, is not itself an OSPF packet type. LSAs are data structures that describe topology or routing information and are carried inside OSPF packets, especially LSU packets. For example, an LSU packet may transport one or more LSAs to a neighbor, and an LSAck packet acknowledges receipt of LSAs. Hello packets discover and maintain neighbor relationships, DD packets summarize LSDB contents during synchronization, and LSR packets request specific missing LSAs. The distinction between an LSA and an LSU is important in Huawei Datacom study material because they operate at different conceptual levels: an LSA is routing information, whereas an LSU is the OSPF protocol packet that transports that information. Therefore, among the choices, LSA is the item that is not one of the five OSPF packet types. The correct answer is B.


NEW QUESTION # 31
Four links between two switches establish an Eth-Trunk in manual mode, and the bandwidth of each link is 1 Gbit/s. One of the links fails. Which of the following statements are true about this scenario? (Select all that apply)

Answer: B,D

Explanation:
In an Eth-Trunk working in manual mode, multiple physical member links are bundled into one logical interface to provide higher bandwidth and link redundancy. If one of four 1 Gbit/s member links fails, the Eth-Trunk does not go down as long as at least one valid member link remains active. Therefore, statement A is correct. Since one link has failed and three member links remain available, the total available bandwidth becomes 3 Gbit/s, so statement B is also correct.


NEW QUESTION # 32
An engineer is configuring Fit AP onboarding on a Huawei WAC. After the engineer completes network connectivity and CAPWAP configuration, the next step is to configure the AP authentication mode. Which AP authentication modes can the engineer choose to configure?
(Choose all that apply.)

Answer: A,B,C

Explanation:
Huawei WAC supports multiple AP authentication modes during Fit AP onboarding, including MAC-based authentication, SN-based authentication, and no-authentication mode. These methods define how the WAC verifies and allows APs to join the network. IP-based authentication is not a valid AP authentication mode in this context.


NEW QUESTION # 33
On the network shown in the figure, the three PCs belong to VLAN 2. When configuring interface- based VLAN assignment, the administrator only forgets to configure the PVID of GE1/0/1.
However, PC1 can still communicate with PC2 at Layer 2.

Answer: B

Explanation:
If GE1/0/1 does not have its PVID configured, it uses the default VLAN (typically VLAN 1). This means PC1's untagged traffic will be placed into VLAN 1 instead of VLAN 2, while PC2 is correctly in VLAN 2. Since they are in different VLANs, Layer 2 communication between PC1 and PC2 is not possible.


NEW QUESTION # 34
In the WLAN networking, multiple APs can broadcast the same SSID and belong to the same BSSID, allowing STAs to stay connected to the same wireless network wherever they move.

Answer: B

Explanation:
In WLAN networks, multiple APs can broadcast the same SSID to provide seamless roaming for STAs, but they do not share the same BSSID. Each AP has a unique BSSID (typically the MAC address of its radio interface). Roaming works based on SSID consistency while maintaining different BSSIDs per AP, so the statement is incorrect.


NEW QUESTION # 35
