Regarding the Stub region and the NSSA region of the OSPF protocol , the following statement is incorrect with a single choice
Correct Answer: B
Question 117
The DHCP protocol assigns to clients-some TCPIP-related parameter information-in the process DHCP defines a variety of messages that are encapsulated at the transport layer :(sortic).
Correct Answer: A
Question 118
In the gRPC-based telemetry protocol, the data model layer consists of theRPC layer,telemetry layer, andservice data layer. Drag the.proto fileto the layer where the file should be located.
Correct Answer:
A screenshot of a computer AI-generated content may be incorrect. Comprehensive and Detailed In-Depth Explanation: ThegRPC-based telemetry protocolutilizesprotocol buffers (.proto files)to define the structure and data format used in communication between a client and a server. In Huawei ' s telemetry architecture, these files are categorized based on their roles in the data model. 1. RPC Layer: File:huawei-grpc-dialin.proto TheRPC layer (Remote Procedure Call layer)handles communication between the client and server. The filehuawei-grpc-dialin.protodefines thegRPC service interfaces, message structures, and procedures for remote method invocation. It is essential forestablishing communicationandinvoking telemetry data collection. Function:Managesdial-in and dial-out connectionsbetween the telemetry client and the server. 2. Telemetry Layer: File:huawei-telemetry.proto Thetelemetry layeris responsible forcollecting, packaging, and exporting telemetry data. The filehuawei-telemetry.protocontains thedata modelused for telemetry reporting, includingstreaming data formatsandtelemetry messages. It defines how thecollected datais organized and transmitted. Function:Provides astructured way to export telemetry datain real-time or batch mode. 3. Service Data Layer: File:huawei-debug.proto Theservice data layercontains data models related todiagnostics, debugging, and operational data. The filehuawei-debug.protois used tocollect debugging informationfrom network devices. This file is crucial fortroubleshooting and monitoring the healthof the system. Function:Facilitatesdebugging and diagnostic telemetry data collection. Why This Mapping Is Correct: The mapping is based on thefunctional role of each layerand thepurpose of each .proto filein the Huawei gRPC-based telemetry architecture. Correctly identifying the file location is crucial foreffective telemetry configurationanddata collection.

Question 119
New IS-IS TLVs are used to carry IPv6 addresses and reachability information to support IPv6 route processing and calculation.
Correct Answer: A
IS-IS was originally designed for IPv4, but extensions via TLVs (Type-Length-Value) allow it to support IPv6. These are referred to as New IS-IS TLVs, including TLV 236 (IPv6 Reachability), TLV 232 (IPv6 Interface Address), etc. These TLVs are crucial for IPv6 route computation within IS-IS. Exact Extract - HCIE-Datacom Guide - IPv6 Routing Protocols Chapter "IS-IS uses new TLVs such as TLV 236 and TLV 232 to carry IPv6 prefix and interface address information. These TLVs are essential to enable IPv6 route calculation." Reference: Huawei HCIE-Datacom Training Manual - IS-IS for IPv6 Support HCIE-Datacom Study Guide - IS-IS TLVs Overview Section
Question 120
MPLS supports both static and dynamic LSP establishment. Which of the following protocols cannot dynamically establish LSPs in MPLS TE scenarios? (Select all that apply)
Correct Answer: A,C,D
InMPLS Traffic Engineering (TE),Label Switched Paths (LSPs)can be established: Statically: Manual configuration. Dynamically: Typically viaRSVP-TE. Protocol roles: RSVP-TE:Used to dynamically establish and signal TE LSPs## OSPF / IS-IS: Act asIGP protocolsand provide TE-related link-state information (like bandwidth) butdo not establish LSPs themselves## BGP: Used forroute advertisement, not forLSP setupin MPLS TE ## Correct answers: A, C, D Reference:Huawei HCIE-Datacom V1.0 Study Guide -Chapter: MPLS TE FundamentalsSection: LSP Establishment Mechanisms
