H19-301_V3.0 Exam Dumps - Huawei HCPA-IP Network Questions and Answers

Understanding Telnet:Telnet is a protocol used for remote management of networkdevices. Unlike console port management, which requires a physical connection, Telnet operates over the network.

Address Requirement:For Telnet communication to occur, the client must have an IP address. This is because Telnet relies on the TCP/IP protocol suite, and communication is established using IP addresses.

Why Not Other Options?

VLAN:A VLAN (Virtual Local Area Network) is a logical segmentation of a network but does not directly represent an address for communication.

AS:An Autonomous System (AS) is a collection of IP networks under a single administrative domain, not an address type.

MAC:A MAC address is a hardware identifier used at Layer 2 of the OSI model. While important for local network communication, it is not sufficient for Telnet, which operates at Layer 3.

Conclusion:The correct answer is IP, as it is the fundamental addressing scheme required for Telnet communication.

YANG (Yet Another Next Generation) is adata modeling languageused to define the structure of configuration and state data manipulated by network management protocols.

NETCONF (Network Configuration Protocol)is a network management protocol thatrelies on YANGto provide a standardized way to configure and manage network devices.

YANG defines the structure, while NETCONF provides the transport mechanism to read, modify, and delete configurations.

Other options explained:

SNMP(Simple Network Management Protocol) is used for monitoring but doesnotuse YANG.

CLI(Command-Line Interface) is a manual method for device configuration andnot standardized by YANG.

Telemetryis used for real-time data streaming but isnot dependent on YANG.

The Huawei CloudEngine S8700-10 is a high-performance aggregation switch designed for enterprise campus networks. It supports up to 4 power modules , which provide redundancy and ensure stable operation even in the event of a power module failure. Redundant power supplies are critical for maintaining network uptime and reliability, especially in mission-critical environments.

The other options (2, 6, and 8) do not match the specifications of the S8700-10. While some models in the S8700 series may support fewer or additional power modules, the S8700-10 specifically accommodates up to 4 power modules.

Overview of Huawei CloudFabric 3.0:

Huawei CloudFabric 3.0 is a next-generation data center network solution that emphasizes automation, intelligence, and unified connectivity for diverse workloads.

Analysis of Each Differentiator:

Full-lifecycle automation:CloudFabric 3.0 provides end-to-end automation for provisioning, configuration, and management, reducing operational complexity.

Network-wide intelligent O&M:AI-driven tools enable proactive fault detection, analysis, and resolution, improving network reliability.

All-wireless access:This is incorrect. CloudFabric 3.0 focuses on wired Ethernet networks rather than all-wireless access.

All-Ethernet storage and HPC network:CloudFabric 3.0 supports unified Ethernet-based connectivity for storage, high-performance computing (HPC), and other workloads, simplifying infrastructure.

Conclusion:The correct differentiators are Options A, B, and D.

Overview of S5731-L Remote Units (RUs):

The S5731-L series includes remote units (RUs) designed for distributed campus networks. These RUs connect to a central switch via uplink ports.

Uplink Port Flexibility:

The RUs supportoptical, electrical, and hybrid optical-electrical ports, allowing flexible selection based on the distance between the RU and the central switch.

Optical ports are used for long-distance connections, while electrical ports are suitable for shorter distances. Hybrid ports combine both options for maximum versatility.

Conclusion:The statement is TRUE because the S5731-L RUs support multiple uplink port types for flexible deployment.

TCP (Transmission Control Protocol) is a connection-oriented protocol with several key characteristics:

Connectionless : This is not a characteristic of TCP. TCP establishes a connection before transmitting data using a three-way handshake.

Flow control and window mechanism : TCP uses flow control and sliding window mechanisms to manage data transmission rates and prevent buffer overflow.

Connection-oriented : TCP establishes, maintains, and terminates connections between endpoints.

Reliable transmission : TCP ensures reliable delivery of data through acknowledgments, retransmissions, and error detection.

UDP, not TCP, is a connectionless protocol. Therefore, the correct answer is A .

Understanding SecoManager Deployment Modes:

SecoManager is a security controller that integrates with Huawei's iMaster NCE platforms to manage security policies across networks.

Analysis of Each Mode:

Integrated deployment with iMaster NCE-IP:Supported for managing security in IP/MPLS networks.

Integrated deployment with iMaster NCE-Fabric:Supported for data center and cloud fabric security management.

Integrated deployment with iMaster NCE-Campus: Not supportedbecause SecoManager focuses on specialized security scenarios, while iMaster NCE-Campus manages campus networks.

Independent deployment:Supported for standalone security management.

Conclusion:The correct answer is Option C, as integrated deployment with iMaster NCE-Campus is not a valid SecoManager deployment mode.
