Manufacturing A.B.C. is a mid-sized international company that specializes in manufacturing industrial equipment. It has operated in the market for more than two decades and has become a reputable participant in its industry. However, rapid technological advances have left its existing network infrastructure outdated and unable to keep pace with modern manufacturing-process demands.

Manufacturing A.B.C.'s network combines legacy wired and wireless components from multiple vendors, resulting in frequent downtime and reduced production efficiency. The aging equipment causes slow data-transfer rates, unreliable connectivity, and greater exposure to cyber threats. Fiber cabling must also be upgraded because OM2 is used for most of it.

Further compounding the network problems, the CTO's recent departure has left the company without a clear direction for the network-refresh project. The management team lacks consensus on the upgrade's scope, budget, and timeline.

The manufacturing customer's primary objectives are as follows:

Improve network performance and reliability to enhance production processes and minimize downtime.

Enhance network security to safeguard sensitive data and intellectual property.

Streamline communication and collaboration among the organization's different departments.

Ensure scalability to support future growth and technological advances.

Manufacturing A.B.C. requires a comprehensive network refresh with these components:

Upgrade the wired infrastructure to high-speed Ethernet switches to support increased data-transfer rates and reduce latency.

Implement a robust wireless solution with enterprise-grade access points that provides seamless connectivity throughout the manufacturing facility.

Use centralized network-management tools to simplify network administration and monitoring.

Expectations:

The customer expects the network-refresh project to be completed efficiently, with minimal disruption to ongoing operations. They seek a reliable, experienced network-solutions provider that understands their specific manufacturing requirements and can deliver a customized solution consistent with their budget constraints. Given the recent CTO change, the manufacturing customer is eager to receive clear project proposals and decision-making support.

As a network-solutions provider, your role is to address these concerns, provide expert guidance, and present a clearly defined plan to meet the objectives effectively.

Manufacturing A.B.C. must regulate various traffic types with QoS, and the architect chose DWRR instead of SP queuing. Which switches support DWRR?

Choose two.
