H19-301_V3.0 Leak Questions

Enterprise networks are vulnerable to a variety of cyberattacks, including:

Remote code execution:Attackers exploit vulnerabilities to execute malicious code on target systems, potentially gaining full control.

Cross-site attacks:Includes Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF), where attackers manipulate web applications to steal data or perform unauthorized actions.

Command line injection:Attackers inject malicious commands into input fields, compromising system integrity.

Brute-force attacks:Attackers attempt to guess passwords or encryption keys through repeated trial-and-error attempts.

These attack methods highlight the importance of implementing robust security measures, such asfirewalls, intrusion detection/prevention systems, and regular patching.

Geographic Redundancy in SD-WAN Controllers:

Huawei's SD-WAN solution provides geographic redundancy to ensure high availability and disaster recovery.

Analysis of Each Statement:

Option A:This is correct. The active and standby clusters share the same domain name or IP address, enabling seamless failover during an active/standby switchover.

Option B:This is correct. Geographic redundancy requires the active and standby clusters to have the same number of nodes to ensure balanced performance.

Option C:This is correct. Huawei's SD-WAN solution supports only one active cluster and one standby cluster for geographic redundancy.

Option D:This is incorrect. While the active and standby clusters synchronize data in real time, only the active cluster provides services. The standby cluster remains idle until a failover occurs.

Conclusion:The FALSE statement is Option D.

Autonomous Driving Network (ADN) Levels:

The ADN standard defines six levels (L0 to L5), ranging from manual operations (L0) to fully autonomous operations (L5).

Highest Level (L5):

AtL5, the network achieves full autonomy, capable of self-configuration, self-optimization, and self-healing without human intervention.

Conclusion:The statement is TRUE because the highest level of the ADN standard is indeed L5: full autonomous network.

Huawei's CloudFabric Easy Solution is designed to simplify data center network deployment and operations. The "EASY" framework highlights the following four key aspects:

EasY-Maintenance : The solution emphasizes simplified operations and maintenance (O&M) through automation and intelligent tools. For example, it leverages AI-powered analytics to predict and resolve issues proactively.

Simplification : CloudFabric Easy focuses on reducing complexity in network design, deployment, and management. It achieves this by integrating advanced technologies like intent-driven networking (IDN) and zero-touch provisioning (ZTP).

Automation : Automation is a cornerstone of the solution, enabling tasks like configuration, provisioning, and troubleshooting to be performed automatically. This minimizes human intervention and reduces the risk of errors.

While "expandability" and "easy sales" are important considerations in network design and marketing, they are not part of the official "EASY" highlights of the CloudFabric Easy Solution.
