HPE7-A03 Exam Dumps : HPE Aruba Networking Certified Network Architect - Campus Access

The role of the Network Designer/Architect in a large-scale network infrastructure project is to develop a detailed technical design that meets the project's requirements. This involves authoring the low-level design documents, which include detailed network diagrams, device configurations, and implementation guidelines. The Network Designer/Architect must understand the technical specifications and business goals to create a solution that is not only technically sound but also aligned with the organization's objectives. This role is critical inensuring that the network infrastructure is designed to be scalable, reliable, and secure, providing a solid foundation for the organization's operations.

A 2-tier campus LAN architecture, consisting of the core and access layers, is typically suitable for smaller campuses or networks with limited numbers of wiring closets. This simplified architecture eliminates the need for a dedicated aggregation layer, which is more common in larger, more complex network environments (the 3-tier architecture). In a small campus setting with only a few wiring closets, a 2-tier design can provide sufficient performance and scalability, reducing complexity and potentially lowering costs. This architecture allows for direct connectivity between the access layer, where end devices connect to the network, and the core layer, which routes traffic to and from the campus network. The use of a 2-tier architecture in such scenarios is driven by the network's size and the simplicity of its requirements, making it an efficient and effective choice.

One of the key advantages of using a Virtual Switching Extension (VSX) pair instead of two discrete switches for connecting servers, storage, firewalls, and other workloads is that bothmembers in a VSX pair can be upgraded without any downtime for the workload (Option C). VSX technology provides advanced high availability features that allow for non-disruptive software upgrades, meaning that one switch in the VSX pair can be upgraded while the other continues to handle network traffic, thereby maintaining continuous operation of the connected workloads. This seamless failover capability ensures that there is no interruption to the critical services running on the network, making VSX an ideal solution for environments where uptime is paramount.
