   A company has a compute workload that is steady, predictable, and uninterruptible. Which Amazon EC2 instance purchasing options meet these requirements MOST cost-effectively? (Choose two.)

   • AOn-Demand Instances
   • BReserved Instances
   • CSpot Instances
   • DSaving Plans
   • EDedicated Hosts

   Show answer

   Answer: BD

   Explanation

   For a steady, predictable, and uninterruptible compute workload, the most cost-effective Amazon EC2 instance purchasing options would typically be: B. Reserved Instances: Reserved Instances provide a significant discount compared to On-Demand Instances in exchange for a commitment to a one- or three-year term. Since the workload is steady and predictable, you can forecast your usage and purchase Reserved Instances accordingly, optimizing costs over time. D. Saving Plans: Similar to Reserved Instances, Savings Plans offer significant discounts on usage in exchange for committing to a specific amount of compute usage (measured in dollars per hour) over a one- or three-year term. Savings Plans provide flexibility across a wider range of instance types and regions compared to Reserved Instances.

   A company wants to migrate its on-premises workloads to the AWS Cloud. The company wants to separate workloads for chargeback to different departments. Which AWS services or features will meet these requirements? (Choose two.)

   • APlacement groups
   • BConsolidated billing
   • CEdge locations
   • DAWS Config
   • EMultiple AWS accounts

   Show answer

   Answer: BE

   Explanation

   B. Consolidated Billing Consolidated billing is a feature of AWS Organizations that allows you to combine billing for multiple AWS accounts. With consolidated billing, each department can have its own AWS account for tracking and managing its resources separately, while the company enjoys the convenience of a single payment method for all these accounts. This setup makes it easier to track costs and implement chargeback mechanisms. E. Multiple AWS Accounts Creating multiple AWS accounts, one for each department, is an effective way to segregate resources, manage permissions, and track costs separately. This approach enhances security by limiting the scope of access and impact of changes, and it simplifies the process of attributing costs to the right department. Combined with consolidated billing, it provides both organizational flexibility and centralized financial control.
