Q95. A company has an internal application that runs on Amazon EC2 instances in an Auto Scaling group. The EC2 instances are compute optimized and use Amazon Elastic Block Store (Amazon EBS) volumes.
The company wants to identify cost optimizations across the EC2 instances, the Auto Scaling group, and the EBS volumes.
Which solution will meet these requirements with the MOST operational efficiency?
A. Create a new AWS Cost and Usage Report. Search the report for cost recommendations for the EC2 instances the Auto Scaling group, and the EBS volumes.
B. Create new Amazon CloudWatch billing alerts. Check the alert statuses for cost recommendations for the EC2 instances, the Auto Scaling group, and the EBS volumes.
C. Configure AWS Compute Optimizer for cost recommendations for the EC2 instances, the Auto Scaling group and the EBS volumes.
D. Configure AWS Compute Optimizer for cost recommendations for the EC2 instances. Create a new AWS Cost and Usage Report. Search the report for cost recommendations for the Auto Scaling group and the EBS volumes.
Answer
C
Q96. A company is running a media store across multiple Amazon EC2 instances distributed across multiple Availability Zones in a single VPC. The company wants a high-performing solution to share data between all the EC2 instances, and prefers to keep the data within the VPC only.
What should a solutions architect recommend?
A. Create an Amazon S3 bucket and call the service APIs from each instance’s application
B. Create an Amazon S3 bucket and configure all instances to access it as a mounted volume
C. Configure an Amazon Elastic Block Store (Amazon EBS) volume and mount it across all instances
D. Configure an Amazon Elastic File System (Amazon EFS) file system and mount it across all instances
Answer
D
Q97. A company uses an Amazon RDS for MySQL instance. To prepare for end-of-year processing, the company added a read replica to accommodate extra read-only queries from the company’s reporting tool. The read replica CPU usage was 60% and the primary instance CPU usage was 60%.
After end-of-year activities are complete, the read replica has a constant 25% CPU usage. The primary instance still has a constant 60% CPU usage. The company wants to rightsize the database and still provide enough performance for future growth.
Which solution will meet these requirements?
A. Delete the read replica Do not make changes to the primary instance
B. Resize the read replica to a smaller instance size Do not make changes to the primary instance
C. Resize the read replica to a larger instance size Resize the primary instance to a smaller instance size
D. Delete the read replica Resize the primary instance to a larger instance
Answer
B
Q98. A company is migrating its databases to Amazon RDS for PostgreSQL. The company is migrating its applications to Amazon EC2 instances. The company wants to optimize costs for long-running workloads.
