Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q206-Q211):

NEW QUESTION # 206
What parameters can a DHCP6 server assign to a DHCPv6 client?

  • A. IPV6 address/prefix
  • B. DNS server address
  • C. SNTP server address
  • D. Gateway address

Answer: A,B,C

Explanation:
* Understanding DHCPv6:
* DHCPv6 (Dynamic Host Configuration Protocol for IPv6) is used to assign configuration parameters to IPv6 clients.
* It supports both stateful and stateless modes:
* Stateful: Assigns IPv6 addresses and other configuration parameters.
* Stateless: Assigns only configuration parameters (e.g., DNS server) without providing IPv6 addresses.


NEW QUESTION # 207
Four routers run IS-IS and have established adjacencies. The area IDs and router levels are marked in the following figure. R1 and R2 are connected through a PPP link, and R3 is the DIS. Which of the following statements are true?

  • A. R2 sends an LSP to R3 and R4 in unicast mode.
  • B. If R1 sends an LSP, R2 needs to send a PSNP for acknowledgment.
  • C. R3 periodically sends CSNPs to implement Level-2 LSDB synchronization.
  • D. If R2 sends a Level-2 LSP, R3 needs to send a PSNP for acknowledgment.

Answer: B,C

Explanation:
R3, as the DIS in the Level-2 domain, periodically sends Complete Sequence Number Protocol Data Units (CSNPs) to ensure LSDB synchronization among Level-2 routers.
R1 and R2 are in a Level-1 domain, and IS-IS requires the receiving router (R2) to acknowledge an LSP from R1 by sending a Partial Sequence Number Protocol Data Unit (PSNP).
IS-IS LSPs in a broadcast network are sent using multicast, not unicast, making option C incorrect.
For Level-2 LSPs, acknowledgments are not provided using PSNP by R3; CSNPs are sufficient for synchronization .


NEW QUESTION # 208
On an IS-IS network, two directly connected routers establish a neighbor relationship through the three-way handshake mechanism by default, regardless of whether the network type is P2P or broadcast.

  • A. FALSE
  • B. TRUE

Answer: B

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
* IS-IS Three-Way Handshake:
* IS-IS uses a three-way handshake to establish neighbor relationships.
* This process is applied on both point-to-point (P2P) and broadcast network types to confirm bidirectional communication.
* P2P Networks:
* Routers directly exchange IS-IS Hello (IIH) packets to establish adjacency.
* Broadcast Networks:
* IS-IS also uses the three-way handshake on broadcast networks to ensure that the Designated Intermediate System (DIS) election and adjacency formation are correct.

NEW QUESTION # 209
The IP prefix list configuration on a Huawei router is shown below. Which of the following routes can match this IP prefix list?
bash
Copy
[huawei] ip ip-prefix test index 10 permit 10.0.0.0 8 less-equal 32

  • A. 10.1.1.0/24
  • B. 10.1.1.0/6
  • C. 10.0.0.0/16
  • D. 10.1.1.1/32

Answer: A,C,D

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. Understanding the Prefix List Configuration:
The command ip ip-prefix test index 10 permit 10.0.0.0 8 less-equal 32 defines the following:
* The prefix base is 10.0.0.0 with a mask length of 8 bits.
* The less-equal 32 condition allows routes with mask lengths ranging from 8 to 32 bits to match.
2. Analysis of Each Route:
Option A: 10.1.1.1/32
* Correct.
* The prefix 10.1.1.1/32 falls within the 10.0.0.0/8 network range and has a mask length of 32 bits, which satisfies the less-equal 32 condition.
Option B: 10.1.1.0/6
* Incorrect.
* The prefix 10.1.1.0/6 has a mask length of 6 bits, which is shorter than the base prefix length of 8. It does not satisfy the condition.
Option C: 10.1.1.0/24
* Correct.
* The prefix 10.1.1.0/24 falls within the 10.0.0.0/8 network range and has a mask length of 24 bits, which satisfies the less-equal 32 condition.
Option D: 10.0.0.0/16
* Correct.
* The prefix 10.0.0.0/16 falls within the 10.0.0.0/8 network range and has a mask length of 16 bits, which satisfies the less-equal 32 condition.
3. Summary:
* The prefixes that match the configuration are 10.1.1.1/32, 10.1.1.0/24, and 10.0.0.0/16.


NEW QUESTION # 210
By default, some security zones are created when Huawei firewalls are enabled. Which of the following security zones is created by users?

  • A. DMZ
  • B. ISP
  • C. Local
  • D. Trust

Answer: A

Explanation:
By default, Huawei firewalls create security zones such as Trust, Untrust, and Local. The DMZ (Demilitarized Zone) is a security zone explicitly created by users. A DMZ is used to isolate an internal network from the external one, providing an additional layer of security by placing public-facing services (e.
g., web servers) in this intermediary zone. This setup ensures that if a public-facing service is compromised, the internal network remains secure. Huawei Firewall configuration steps confirm this zoning principle, making DMZ creation an explicit user-driven action .
