A Solutions Architect is designing a service that must have four Amazon EC2 instances running between 8 AM and 6 PM daily. The service requires one EC2 instance outside of those hours.
What is the MOST cost-effective way to provide enough compute?
A. Use one Amazon EC2 Reserved Instance and use an Auto Scaling group to add and remove EC2 instances based on CPU utilization.
B. Use one Amazon EC2 On-Demand instance and use an Auto Scaling group to add and remove EC2 instances based on CPU utilization.
C. Use one Amazon EC2 On-Demand instance and use an Auto Scaling Group scheduled action to add three EC2 Spot instances at 7:30 AM and remove three instances at 6:10 PM.
D. Use one Amazon EC2 Reserved Instance and use an Auto Scaling Group scheduled action to add three EC2 On-Demand instances at 7:30 AM and remove three instances at 6:10 PM.C or D ?

A company is storing application data in Amazon S3 bucket across multiple AWS Regions. Company policy requires that encryption keys be generated at the company headquarters, but the encryption keys may be stored in AWS after generation. The Solutions Architect plans to configure cross-region replication.
Which solution will encrypt the data while requiring the LEAST amount of operational overhead?
A. Configure the application to write to an S3 bucket using client-side encryption.
B. Configure S3 buckets to encrypt using AES-256.
C. Configure S3 object encryption using AWS CLI with Server_Side Encryption with AWS KMS_managed keys (SSE-KMS)
D. Configure S3 bucket to use Server-Side encryption with AWS KMS-Management Keys (SSE-KMS) with imported key met— in both region.C or D ?
