   A company is migrating a real-time analytics platform to the cloud. The platform ingests data from multiple sources, processes it, and provides dashboards. The current on-premises environment has 32 vCPUs and 128 GB RAM. The migration team has identified that the cloud instance type with similar specs has a network throughput of 10 Gbps, while the on-premises server has 1 Gbps. The team is concerned about network latency between the application and the database. What should they do to validate performance before migration?

   • AAssume the cloud instance will perform better because of the higher network throughput
   • BUse the on-premises performance metrics as a baseline and select an instance with higher specs
   • CMigrate the application and monitor performance after go-live
   • DRun a benchmark that simulates the expected workload, including network traffic, on the target instance type

   A company is migrating a database server to the cloud. The database currently handles 5,000 transactions per second with an average latency of 10 ms. The migration team needs to ensure the cloud instance can meet these performance requirements. What should they do before finalizing the instance size?

   • AUse the on-premises server's hardware specifications to choose an equivalent cloud instance
   • BMigrate the database and monitor performance after go-live
   • CRun a benchmark test on a candidate instance using a representative workload
   • DSelect the largest instance available to ensure headroom
