H19-301_V3.0 Exam Dumps - HCSA-Presales-IP Network Certification V3.0

TheAC6805is a high-performance wireless access controller (AC) designed for large-scale enterprise networks. It supports a maximum forwarding rate of120 Gbps, enabling it to handle high-density wireless traffic efficiently.This capability makes the AC6805 suitable for environments with thousands of concurrent users, such as stadiums, airports, and large campuses. Its high forwarding rate ensures minimal latency and optimal performance for mission-critical applications.

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.

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.

Huawei firewalls come preconfigured with several default security zones, each serving a specific purpose:

DMZ (Demilitarized Zone):A buffer zone between the internal network and external networks, often used to host public-facing servers like web servers.

Local:Represents the firewall itself. Traffic destined for the firewall (e.g., management traffic) is associated with this zone.

Untrust:Represents external, untrusted networks such as the Internet. Security policies typically restrict traffic from this zone.

Trust:Represents internal, trusted networks. Traffic within this zone is generally considered safe.

These zones form the foundation of firewall security policies, allowing administrators to control traffic flows between different parts of the network.
