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

Fat APs(Autonomous APs) operateindependentlyand donotrequire a centralized wireless controller.

Theyperform all wireless functions, including:

Wireless authentication

Encryption

User access management

Data packet forwarding

Fit APs, on the other hand, depend on a wireless controllerfor centralized management.

Fat APs are best suited for small-to-medium networkswhere centralized control is unnecessary.

Understanding SRv6 Capabilities:

SRv6 (Segment Routing over IPv6) is a next-generation networking technology that enables flexible traffic engineering and seamless traversal across different types of private lines.

Huawei NetEngine AR821 E Support for SRv6:

TheNetEngine AR821 Erouter supports SRv6, making it suitable for SD-WAN andWAN deployments where traffic optimization and path control are critical.

Conclusion:The statement is TRUE because SRv6 can traverse all types of private lines, and the NetEngine AR821 E supports SRv6.

iMaster NCE (Network Cloud Engine) uses NETCONF (Network Configuration Protocol) to deliver configurations to network devices. NETCONF is an XML-based protocol that provides a standardized way to configure and manage network devices programmatically.

Telemetry : Used for collecting operational data from devices, not for configuration delivery.

SDN : Refers to a broader concept of software-defined networking, not a specific protocol.

RESTful : Used for API interactions but not for device configuration.

Thus, the correct answer is A , as NETCONF is the primary protocol used by iMaster NCE for configuration delivery.

MACsec (Media Access Control Security)is a Layer 2 encryption protocol that ensures secure and reliable communication over Ethernet links. Among Huawei'sNetEngine 8000 series routers, the following models support MACsec:

NetEngine 8000 M6:High-performance router with MACsec support for secure WAN connections.

NetEngine 8000 MIC:Modular interface card-based router with MACsec capabilities.

NetEngine 8000 F1A:Fixed configuration router supporting MACsec for secure access links.

TheNetEngine 8000 MIAdoes not support MACsec, making it unsuitable for scenarios requiring Layer 2 encryption.

Hyper-converged data center network solutions emphasize automation across the entire lifecycle, from deployment to operations. Below is an analysis of each option:

100% unleashing of computing power : While automation can optimize resource allocation, achieving 100% utilization of computing power is not directly tied to full-lifecycle automation.

TTM reduced by 90% : Full-lifecycle automation streamlines processes such as provisioning, configuration, and scaling, significantly reducing Time-to-Market (TTM). This is a direct benefit of automation.

Proactive prediction of 90% of faults : Proactive fault prediction is typically achieved through AI-driven analytics, not solely through automation.

Storage performance improved by 90% : Improvements in storage performance are more closely related to advancements in hardware (e.g., NVMe over Fabrics) and software optimizations, rather than automation.

Thus, the correct answer is B , as full-lifecycle automation primarily reduces TTM.

Comprehensive and Detailed in Depth Explanation:An MPLS (Multiprotocol Label Switching) network uses Label Switched Paths (LSPs) to forward packets. However, an LSP is unidirectional , not bidirectional. This means that the path is established in one direction only, from the ingress Label Edge Router (LER) to the egress LER. For bidirectional communication, two separate LSPs are required—one for each direction.

This concept is critical in understanding MPLS architecture, as it ensures efficient packet forwarding based on labels rather than IP addresses. The unidirectional nature of LSPs allows for better traffic engineering and control over data flow in MPLS networks.

ALocal Area Network (LAN)connectsdevices within a limited geographic areasuch as an office, campus, or home.

LANs typically include:

Switches

Routers

Access Points

Computers, printers, and other end devices

LANs operate using Ethernet or Wi-Fiand providehigh-speed communication and resource sharingwithin the network.

Unlike WANs (Wide Area Networks), LANs do not rely on carrier-leased connectionsand cover smaller areas.
