   A university runs a student records system on-premises that contains sensitive data and must comply with strict data residency regulations. The university wants to move its public website to the cloud to handle traffic spikes during enrollment. The website does not access the student records system. Which benefit does a hybrid migration provide in this scenario?

   • AIt requires the website to be re-architected to work with the student records system.
   • BIt eliminates the need for the on-premises data center entirely.
   • CIt allows the university to keep sensitive data on-premises while scaling the public website in the cloud.
   • DIt automatically ensures the student records system is compliant with cloud regulations.

   A retail company's on-premises inventory management system is a monolithic application that is tightly coupled to a legacy database and has frequent performance issues. The company wants to move to the cloud and take full advantage of cloud-native features like auto-scaling and managed services. The leadership team accepts a longer timeline and higher initial cost in exchange for a solution that is not constrained by the legacy architecture. Which migration approach should the company choose?

   • APhased migration, by moving the application first and the database in a later phase.
   • BRip and replace, by re-architecting the application into microservices and using a managed cloud database.
   • CHybrid migration, by keeping the legacy database on-premises and moving only the application to the cloud.
   • DLift and shift, by copying the VM to the cloud and keeping the same monolithic architecture.

   A government agency is migrating a large portfolio of applications to the cloud. The agency has a strict requirement that no single application migration should cause a prolonged service disruption. The agency also wants to learn from each migration to improve the process for subsequent applications. Which advantage does a phased migration provide in this context?

   • AIt allows the agency to migrate applications incrementally, reducing the risk of prolonged disruption and enabling process improvement.
   • BIt ensures that all applications are migrated in a single, coordinated cutover.
   • CIt eliminates the need for testing each application after migration.
   • DIt requires the agency to rewrite all applications to be cloud-native.
