Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q12-Q17):

NEW QUESTION # 12
ON a stateful inspection Firewall where there is no session table, when the status detection mechanism is enabled and the second packet (CYN+ACK) of 3-way hadshakes reaches the firewall. Which of the following statements is true?

A. If the firewall security policy permits packets to pass, the session table is created.
B. If the firewall security policy permits packets to pass, the packets can pass the firewall.
C. By default, when status detection is disabled and the permit policy is configured packets can pass.
D. Packets must pass the firewall, and a session table is established.

Answer: B

NEW QUESTION # 13
In IP multicast transmission, packets are transmitted from a source to a group of receivers. Which of the following statements are true about IP multicast technologies?

A. Compared with unicast, IP multicast increases the load of information sources.
B. Compared with broadcast, IP multicast prevents information flooding.
C. Compared with unicast, IP multicast improves information transmission security.
D. Compared with broadcast, IP multicast effectively conserves network bandwidth.

Answer: B,D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
* IP Multicast vs. Broadcast:
* A. TRUE # Unlike broadcast, which sends data to all hosts in a subnet, multicast only sends data to interested receivers, preventing flooding.
* B. TRUE # Multicast optimizes bandwidth usage by sending a single copy of data, which is then replicated at network routers only when necessary.
* IP Multicast vs. Unicast:
* C. FALSE # Multicast does not improve security; it may expose data to unintended receivers if not properly controlled.
* D. FALSE # Multicast reduces the load on the source because a single data stream serves multiple receivers instead of sending individual unicast streams.
# Reference: Huawei HCIA-Datacom Study Guide, IP Multicast Principles and Benefits.

NEW QUESTION # 14
As shown in the figure, the stateful inspection firewall forwards the packet because the packet matches the session status of the firewall.

A. FALSE
B. TRUE

Answer: B

Explanation:
A stateful inspection firewall tracks the state of active connections. If a packet matches an existing session in the firewall's state table, it is allowed to pass. The diagram indicates that the TCP packet matches the session state, so the firewall forwards it .

NEW QUESTION # 15
A large shopping mall configures a VLAN pool to prevent network performance deterioration caused by potentially large broadcast domains.
A network engineer runs the display vlan pool name STA command to check information about the VLAN pool.
The following command output is displayed:
<AC> display vlan pool name STA Name : STA Total : 2 Assignment: hash Threshold Notify Count: 3 Threshold Notify time(min): 3 VLAN ID : 2 4
Which of the following statements are true?

A. The VLANs with the IDs of 2 and 4 are added to the VLAN pool.
B. The name of the VLAN pool is STA.
C. The total number of VLAN pools is 2.
D. The VLAN pool uses the even VLAN assignment algorithm.

Answer: A,B

Explanation:
The command output confirms that the VLANs with IDs 2 and 4 are part of the VLAN pool named "STA." The VLAN pool concept is used to allocate VLANs dynamically to devices or subnets, which reduces broadcast domain size and improves network efficiency. The total number of VLAN pools is unrelated to this output, and the assignment algorithm (hash or even) is not explicitly mentioned in the output. Huawei VLAN pool management references align with this analysis .

NEW QUESTION # 16
Four routers run IS-IS and have established adjacencies. The area IDs and router levels are marked in the following figure. Which of the following statements is true?

A. The LSDB of R2 does not contain the LSP of R4.
B. The LSDB of R2 does not contain the LSP of R3.
C. The LSDB of R1 does not contain the LSP of R4.
D. The LSDB of R3 does not contain the LSP of R4.

Answer: C

Explanation:
R1 is a Level-1 router in Area 49.0001, while R4 is in Area 49.0004. Level-1 routers only maintain LSDBs for their own area and do not contain LSPs from other areas, such as R4's LSP.
R2 is a Level-1-2 router, so it maintains LSDBs for both Area 49.0001 (Level-1) and Level-2 domains, which include LSPs from R4.
R3 and R4, as Level-2 routers, exchange LSPs with each other within the Level-2 domain.
Thus, the LSDB of R1 does not include R4's LSP .
