   A university IT team manages the campus network using an Agile approach. They run two-week sprints and each sprint includes a review of network performance metrics and user feedback. How does this approach affect network optimization?

   • AOptimization is not possible because the network design is fixed at the start.
   • BOptimization is a one-time activity performed after the entire network is deployed.
   • COptimization is deferred until the end of the project to avoid disrupting sprints.
   • DOptimization is an ongoing process, with adjustments made in each sprint based on performance data.

   An e-commerce company is redesigning its network to support a new microservices platform. The platform will be deployed in phases, and the network must be able to accommodate new services without major redesigns. The team plans to use an Agile approach. What is a key architectural principle that supports this?

   • AA modular network design that can be extended incrementally.
   • BA monolithic network design that is fully specified upfront.
   • CA design that is documented only after the entire project is complete.
   • DA design that is fixed after the first sprint and cannot be changed.

   A software company is moving its development environment to a new network segment. The developers are using a microservices architecture and expect to add new services frequently. The network team wants to avoid a long upfront design phase and prefers to adjust the network as services are added. Which approach is most appropriate?

   • AAgile, because it supports incremental design and implementation, allowing the network to evolve with each new service.
   • BWaterfall, because a complete network design is needed before any service can be deployed.
   • CAgile, but only for the implementation phase, while the design is completed upfront using Waterfall.
   • DHybrid, using Waterfall for the core network and Agile for the services, to balance stability and flexibility.

   A startup is building a new network for its cloud-based services. The requirements are expected to change rapidly as the company pivots. The team wants to deliver a basic network quickly and then enhance it based on customer feedback. Which methodology is most suitable?

   • AAgile, but only for the implementation phase, while the design is done upfront.
   • BHybrid, using Waterfall for the initial design and Agile for enhancements.
   • CAgile, because it supports iterative development and adaptive planning.
   • DWaterfall, because it provides a stable and predictable network design.
