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

Multi-Campus network interconnection involves connecting multiple geographically dispersed campuses into a unified network. To meet the demands of such networks, the following service requirements must be addressed:

Manage LAN-side and WAN-side services in a unified manner : Unified management simplifies operations by providing a single interface to monitor and control both local area networks (LANs) and wide area networks (WANs).

Improve the network deployment efficiency and shorten the service provisioning period : Automation tools and software-defined networking (SDN) technologies help streamline deployment processes, reducing the time required to roll out new services.

Reduce the costs for WAN interconnection between branches : Cost optimization is achieved through efficient use of bandwidth, leveraging technologies like SD-WAN and traffic engineering to minimize expenses.

Improve the application identification capability and ensure the experience of key services : Advanced analytics and AI-driven insights enable precise application identification, prioritizing critical services to ensure optimal user experience.

Adopt a visualized method to simplify management and O&M : Visualization tools provide intuitive dashboards and real-time monitoring, making it easier to manage complex networks and troubleshoot issues.

All five options are valid service requirements for Multi-Campus network interconnection, making them all correct.

Understanding the Network Layer:

The network layer (Layer 3 of the OSI model) is responsible for end-to-end packet delivery, including routing and addressing. Protocols operating at this layer handle logical addressing and path determination.

Explanation of Each Protocol:

IPv6:The next-generation Internet Protocol, which operates at the network layer to provide addressing and routing for packets.

ICMPv6:Internet Control Message Protocol version 6, used for error reporting and diagnostic functions in IPv6 networks. It operates at the network layer.

IPv4:The current widely-used Internet Protocol, which operates at the network layer to provide addressing and routing for packets.

OSPF:Open Shortest Path First is a dynamic routing protocol that operates at the network layer to exchange routing information between routers.

ICMP:Internet Control Message Protocol, used for error reporting and diagnostic functions in IPv4 networks. It operates at the network layer.

Conclusion:IPv6, ICMPv6, IPv4, and ICMP all operate at the network layer. OSPF is also correct because it is a routing protocol that works at Layer 3.

Huawei'sAirEngineseries access points (APs) are designed for high-performance wireless networking. Some models include2.5GE uplink portsto support higher bandwidth requirements for modern applications like video streaming and IoT. The following models support 2.5GE uplink ports:

AirEngine 5760-51:High-performance Wi-Fi 6 AP with 2.5GE ports.

AirEngine 5761-21:Compact Wi-Fi 6 AP with 2.5GE ports.

AirEngine 6761-21T:Outdoor Wi-Fi 6 AP with 2.5GE ports.

TheAirEngine 6761-21andAirEngine 5762-12do not support 2.5GE uplink ports, making them unsuitable for scenarios requiring higher bandwidth.

Understanding MACsec:

MACsec (Media Access Control Security) provides Layer 2 encryption to secure data transmission between network devices, ensuring confidentiality and integrity.

Analysis of Each Model:

NetEngine 8000 M6:This model supports MACsec, making it suitable for secure WAN and DCI deployments.

NetEngine 8000 MIC:This model does not support MACsec.

NetEngine 8000 F1A:This model supports MACsec, enabling secure communication in high-performance networks.

NetEngine 8000 MIA:This model does not support MACsec.

Conclusion:The correct models supporting MACsec are Options A (NetEngine 8000 M6) and C (NetEngine 8000 F1A).
