Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q254-Q259):

NEW QUESTION # 254
The VRID of the VRRP virtual router is 3 and the virtual IP address is 100.1.1.10. What is the virtual MAC address?

  • A. 01-00-5E-00-01-03
  • B. 00-00-5E-00-01-64
  • C. 01-00-5E-00-01-64
  • D. 00-00-5E-00-01-03

Answer: D

Explanation:
The virtual MAC address for a VRRP virtual router is determined by the formula 00-00-5E-00-01-[VRID in hexadecimal]. For VRID 3, the hexadecimal equivalent is 03. Thus, the virtual MAC address is 00-00-5E-00-
01-03 .


NEW QUESTION # 255
Which of the following routing protocols support the default route through command configuration?

  • A. IS-IS
  • B. BGP
  • C. ICMP
  • D. OSPF

Answer: A,B,D

Explanation:
BGP, IS-IS, and OSPF support the configuration of default routes through specific command configurations.
For example, BGP uses the default-originate command, IS-IS uses a default-route-advertise method, and OSPF can advertise default routes using default-information originate. ICMP, however, is not a routing protocol and does not support this functionality .


NEW QUESTION # 256
If a router ID is configured in both the system via and the BGP view, BGP uses the router ID configured in the BGP view because the BGP view takes precedence over the system view.

  • A. FALSE
  • B. TRUE

Answer: B

Explanation:
When the router ID is configured in both the system view and the BGP view, the router ID in the BGP view takes precedence because BGP-specific configurations override global settings. This ensures that BGP operates with the most relevant configurations .


NEW QUESTION # 257
Huawei modular devices have multiple hardware modules that provide different functions. Match the following hardware modules with their functions.

Answer:

Explanation:

Explanation:
The hardware modules of Huawei modular devices and their functions are:
Main Processing Unit (MPU):Provides control and management planes for the entire system, responsible for protocol processing, system security, and software upgrades.
Switch Fabric Unit (SFU):Provides the data plane, enabling high-speed data switching between service modules.
Line Processing Unit (LPU):Manages data forwarding, offering various interfaces (optical and electrical) for data access.


NEW QUESTION # 258
On an OSPF network, LSDBs are used to store LSAs. Common LSAs include router LSAs and network LSAs. Which of the following items is not included in the 3-tuple that is used to uniquely identify an LSA?

  • A. LSType
  • B. Link State ID
  • C. LS Sequence Number
  • D. Advertising Router

Answer: C

Explanation:
Comprehensive and Detailed in-depth Step-by-Step Explanation:
In OSPF,Link State Advertisements (LSAs)are used to exchange routing and topology information. Each LSA in the OSPF network is uniquely identified using a3-tuple identifier, which consists of:
Link State ID:
The Link State ID uniquely identifies the LSA within the OSPF area. Its value depends on the LSA type. For example, for a Router LSA, the Link State ID is the originating router's Router ID.
Advertising Router:
This is the Router ID of the router that generated the LSA. It identifies which router is responsible for creating and advertising this LSA.
LSType:
This field identifies the type of LSA (e.g., Router LSA, Network LSA, Summary LSA, AS-External LSA, etc.). It is crucial for interpreting the purpose and content of the LSA.
TheLS Sequence Numberis not part of the 3-tuple that uniquely identifies the LSA. Instead, it is used to determine the most recent version of the LSA in case there are multiple instances of the same LSA.
