A company runs an Amazon EC2 workload continuously (24/7) and will need the same instance family and type for the next 12 months. Which combination of purchasing options will MOST reduce costs? (Choose two.)

Standard Reserved Instances offer the deepest discounts for a consistent, long-term workload with unchanging instance type and region, making them ideal for a 24/7 workload over 12 months. Convertible Reserved Instances provide flexibility to change instance families, but offer smaller discounts than Standard RIs, making them less cost-effective for a fixed workload. Compute Savings Plans offer flexible discounts across compute services but may not provide the maximum savings for a specific, unchanging EC2 instance like a Standard RI does. Spot Instances are for fault-tolerant workloads that can tolerate interruptions and are unsuitable for continuous, uninterrupted operations. All Upfront payment further maximizes the discount on Reserved Instances by paying the entire cost at the beginning of the term, leading to the lowest overall cost.
