Huawei Updated H19-301_V3.0 Exam Questions and Answers by dillon

Understanding Overlay Topologies in SD-WAN:

In Huawei's SD-WAN solution, overlay networks are created on top of the physical underlay network. These overlays can be customized based on specific services or applications.

Service Independence:

Different service topologies (e.g., voice, video, data) areindependent of each other, allowing granular control over traffic paths, QoS policies, and security settings.

Conclusion:The statement is TRUE because overlay topologies in Huawei's SD-WAN solution are service-specific and operate independently.

SecoManager is Huawei's security controller, designed to provide centralized management and intelligent orchestration for various security devices. Below is an analysis of each option:

Identification of the real attack source IP addresses of botnets based on machine learning, enhancing defense against CC attacks : SecoManager uses AI and machine learning to analyze traffic patterns and identify malicious activities, such as botnet attacks and CC (Challenge Collapsar) attacks.

Policy redundancy analysis : This is not a feature of SecoManager. While it provides policy management, redundancy analysis is typically handled by other tools or controllers.

High-performance collection, query, and storage of session logs and threat logs : SecoManager collects and analyzes logs from security devices, enabling administrators to monitor threats and troubleshoot issues efficiently.

Unified management of multiple security devices, including firewalls, IPS devices, and anti-DDoS devices : SecoManager integrates with various security devices, providing a single platform for configuration, monitoring, and policy enforcement.

Thus, the correct answers are A , C , and D .

Comprehensive and Detailed in Depth Explanation:WPA3 (Wi-Fi Protected Access 3) introduces enhanced security features compared to WPA2. One of the key improvements is the use of a 192-bit encryption key in the WPA3 Enterprise mode, which provides stronger cryptographic protection. This is part of the "WPA3-Enterprise 192-bit" mode, designed for high-security environments such as government and financial institutions.

The increased key length enhances resistance to brute-force attacks and ensures better protection of sensitive data. Additionally, WPA3 includes features like Simultaneous Authentication of Equals (SAE), which replaces the Pre-Shared Key (PSK) mechanism, further improving security.

Huawei's datacom portfolio includes the "Four Engines," which represent key product lines for different networking domains:

NetEngine:High-performance routers for enterprise WAN and data center interconnects.

CloudEngine:Data center switches designed for high-density, low-latency environments.

AirEngine:Wireless access points (APs) for Wi-Fi 6 and beyond.

HiSecEngine:Security products, including firewalls and intrusion prevention systems.

The optionAREnginedoes not belong to the "Four Engines" lineup. It appears to be unrelated to Huawei's official datacom product categories.
