HP HPE7-A03 Exam With Confidence Using Practice Dumps

Capacity based design with low to mid density - Basic office/cubicle area with low to medium user density and no voice with limited rf redundancy.

Coverage based design - Coverage, office areas with higher user density OR basic coverage office/cubicle with High Demand users

High-capacity design - High user density indoor space, with high demand users

Very low-density, low coverage - Warehouses, large open areas

The types of wireless network deployment should be matched to the usage scenarios based on the density of users and coverage requirements:

Capacity based design with low to mid density is suitable for basic office or cubicle areas where there are not many users, and high-performance voice applications are not a priority, thus limited RF redundancy may be acceptable.

Coverage based design is intended for areas where coverage is more critical than capacity. It could be used in office areas with higher user density, where maintaining a basic level of connectivity is more important than accommodating a large number of high-bandwidth connections.

High-capacity design is used in environments where there is a high density of users who are likely to be using bandwidth-intensive applications. This could include indoor spaces like conference centers, auditoriums, or any area with a high concentration of users and devices.

Very low-density, low coverage is typically for spaces like warehouses or large open areas where there are few users spread out over a large area. The focus here is on providing coverage to all areas, regardless of the low user density.

Customer Requirement Recap (cruise line scenario):

Each ship has two core switches in the MDF.

Each core connects to up to 10 distribution switches in IDFs.

Uplinks between core and distribution are 25 GbE SMF links.

Cabins/technical rooms connect to distribution switches via 10 GbE uplinks.

Only 8 uplinks per core switch are required to meet the design.

Issue Identified:

The selected core switch platform provides dozens of 25/40/100 GbE ports, far exceeding what is needed for this environment.

With only 8 ports in use per core, that leaves ~40 unused ports.

This creates a cost inefficiency — the customer is paying for hardware capacity that will remain idle.

Why the Correct Answer is B:

The main “issue” is not about lack of capability (uplinks and VSX are supported).

The issue is about overprovisioning — the core switch selection results in a large number of unused ports, which is against the CIO’s requirement to limit unused capacity and avoid waste.

Why Not the Other Options:

A. Core will not support 25 GbE downlinks → Incorrect. The selected core switches do support 25 GbE uplinks.

C. Not enough ports for VSX links → Incorrect. Core switches only require a few ports for VSX interconnect, which is easily supported.

D. Core will not support 10 GbE downlinks to cabins → Incorrect. Core switches don’t connect directly to cabins; those connections terminate at the distribution layer.

Aruba Design Guide Reference:

Aruba ESP Campus Design Principles: Switch sizing should consider right-sizing the port count to avoid excessive unused capacity.

Aruba Validated Solution Guides: Core switches should be selected for performance, scalability, and efficiency — not overspec’d beyond realistic need.

Final Justification:

The issue with the customer’s core switch selection is not about functionality, but about efficiency. Only 8 uplinks per core are needed, leaving ~40 ports unused — which contradicts the CIO’s goal of minimizing unused ports.

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 in ensuring that the network infrastructure is designed to be scalable, reliable, and secure, providing a solid foundation for the organization's operations.
