Huawei H19-301_V3.0 HCSA-Presales-IP Network Certification V3.0 Exam Practice Test

Answer : B

TheUSG6000E-Bfirewall doesnotsupport hardware bypass by default. If hardware bypass functionality is required, anexternal bypass devicemust be purchased and configured.Hardware bypass ensures network continuity in case of a firewall failure by physically rerouting traffic around the device. Since this feature is not included by default in the USG6000E-B, additional hardware is necessary to achieve it.

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.

Answer : C

To defend againstapplication-layer DDoS attacks, Huawei'sAntiDDoSproduct is the most suitable choice.Key details about the options:

HiSec Insight:A security analytics platform for threat detection and response, but not specifically designed for DDoS mitigation.

USG6000E:A next-generation firewall with basic DDoS protection, but limited in handling large-scale or sophisticated attacks.

AntiDDoS:A dedicated solution for detecting and mitigating DDoS attacks, including application-layer attacks like HTTP floods.

FireHunter:A sandboxing solution for advanced threat detection, not DDoS defense.

TheAntiDDoSproduct excels in identifying and mitigating application-layer attacks by analyzing traffic patterns and applying granular mitigation policies.

Answer : B

While Huawei'sUSG series firewallsinclude basicanti-DDoS capabilities, they are not designed to completely replace standaloneanti-DDoS products. Firewalls primarily focus on access control, threat prevention, and policy enforcement, whereas dedicated anti-DDoS solutions offer advanced features like large-scale traffic scrubbing, anomaly detection, and mitigation for massive DDoSattacks.For environments facing sophisticated or volumetric DDoS threats, standalone anti-DDoS appliances or cloud-based services are recommended to complement firewall capabilities.
