You are a network architect for a large organization. The organization is planning to upgrade its network infrastructure to application. The application requires high availability, secure data transfer, and efficient handling of large data volumes. Which of the following network design considerations best aligns with the requirements of the new business application? Implementing a layered network design based on the OSI model with appropriate security controls at each layer. Implementing a flat network design with all devices on the same network segment. Implementing a network design with minimal use of routers to reduce complexity. Implementing a network design that prioritizes cost reduction over scalability and resilience.

Implementing a layered network design based on the OSI model with appropriate security controls at each layer is crucial for ensuring both high availability and secure data transfer. This approach allows for isolating different functions and services, enhancing security by applying specific controls tailored to each layer’s requirements. Such a design can also improve fault tolerance, as failures in one layer won't necessarily impact others, ultimately leading to a more resilient infrastructure. In the realm of real-world applications, many large enterprises utilize this layered approach to not just bolster security but also to maintain operational efficiency. For example, cloud service providers often rely on this model to manage their huge data volumes while providing uptime guarantees and secure access. Adopting a structured design strategy like this can significantly reduce the risks associated with data breaches and service outages, making it a favored choice among organizations aiming for robust network performance.
