Huawei H19-301_V3.0 Exam Questions

Environmental Tolerance of Huawei NetEngine 8000 Series:

The Huawei NetEngine 8000 series is designed for robust performance in challenging environments, including extreme temperatures.

Temperature Range and Outdoor Installation:

These routers are certified to operate in temperatures ranging from-40C to +65C, making them suitable for deployment in outdoor cabinets or harsh conditions.

Conclusion:The statement is TRUE because the NetEngine 8000 series supports the specified temperature range and can be installed in outdoor cabinets.

Understanding the Role of RR (Route Reflector):

In Huawei's SD-WAN solution, the Route Reflector (RR) plays a critical role in distributing routing information and ensuring efficient communication between CPEs (Customer Premises Equipment).

Analysis of Each Statement:

Option A:This is FALSE. The RR in Huawei's SD-WAN solution doesnot directly implement communicationbetween SD-WAN networks and legacy MPLS networks. Instead, it focuses on distributing VPN routes and tunnel information within the SD-WAN overlay network. Communication with legacy MPLS networks typically requires additional integration mechanisms.

Option B:This is correct. The RR can be deployed on a physical AR router or as a virtualized instance (AR1000V vCPE).

Option C:This is correct. The RR can be deployed independently or co-located witha CPE at a site, depending on the network design.

Option D:This is correct. The RR distributes VPN routes and tunnel information between CPEs based on predefined VPN topology policies.

Conclusion:The FALSE statement is Option A.

TheNetEngine 8000 M14is a high-performance aggregation router designed for enterprise and carrier networks. Key features include:

Compact design:With a depth of220 mm, it fits well in space-constrained environmentslike edge locations.

Control/forwarding separation:Ensures efficient processing by separating control plane and forwarding plane functions.

Hardware redundancy:Provides high reliability through redundant components like power supplies and fans.

These features make the NetEngine 8000 M14 a robust choice for aggregation roles in WAN architectures.

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.

SNMP (Simple Network Management Protocol) is a widely used protocol for managing and monitoring network devices. In an SNMP-based network:

Each managed device runs anagent processthat collects and stores management information.

Themanagement process(typically running on a Network Management System, or NMS) communicates with the agent using SNMP messages.

SNMP defines several types of messages, such as GET, SET, and TRAP, which allow the NMS to query or modify device configurations and receive notifications from the agent. Other options like NETCONF, HTTP, and YANG are unrelated to SNMP communication.
