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.

Comprehensive and Detailed Explanation From Exact Extract:

Why ArubaOS 10 (AOS10):

ArubaOS 10 is the current next-generation WLAN architecture, designed for both campus and distributed branch deployments.

It supports cloud-native management via Aruba Central, aligning with ACME’s move to the cloud.

Provides scalability for 7+ years, meeting the long-term investment requirement.

Supports Wi-Fi 6/6E APs, which are essential for high-density retail and warehouse environments.

Why Gateways are Needed:

Gateway role is critical to support:

Tunneled traffic for segmentation (guest, vendor, employee).

Cloud Guest Authentication and captive portal functions for customers.

Application visibility and role-based policy enforcement.

Integration with SD-Branch WAN for resilience and cost control across remote stores.

Gateways ensure the unified policy enforcement across all sites (head office, branches, warehouses, retail stores).

Why Not the Other Options:

B (InstantOS 8): Outdated architecture, limited to smaller standalone AP deployments, not recommended for enterprise growth or cloud-centric operations.

C (AP-only AOS10): Provides Wi-Fi but lacks gateways, meaning no central policy enforcement, tunneling, or role-based segmentation. This would not meet ACME’s requirements for guest/vendor access control, WAN resiliency, and security.

D (ArubaOS 8 campus): Legacy controller-based solution, being phased out in favor of AOS10. Does not align with cloud-first and future-ready requirements.

Requirement Mapping to AOS10 AP + Gateway deployment:

Real-time inventory & Zebra scanners → Reliable Wi-Fi 6E AP coverage with low latency.

Cloud-based operations → Aruba Central + AOS10 integration.

Guest, vendor, employee segmentation → Policy enforcement firewall and dynamic segmentation via gateway tunneling.

Warehouses with high ceilings → Wi-Fi 6E APs with appropriate antenna design (AOS10 supports full AP portfolio).

Cut IT staff in half → AI Insights and automation in Aruba Central reduce troubleshooting complexity.

Marketing customer interaction → Cloud guest services and analytics integration with Aruba Central.

7+ year lifecycle → AOS10 architecture is future-proof and actively developed, unlike legacy OS8.

Final Justification:

The only solution that meets all customer requirements (cloud-based management, role-based segmentation, tunneling, guest/vendor access, real-time inventory, scalability, and 7+ years longevity) is an ArubaOS 10 AP and Gateway deployment.
