(Choose two.)

A. AWS Batch
B. Network Load Balancer
C. Application Load Balancer
D. Amazon EC2 Auto Scaling
E. Amazon S3 website hosting

C. Application Load Balancer
D. Amazon EC2 Auto Scaling

A company uses an Amazon S3 bucket to store static images for its website. The company configured permissions to allow access to Amazon S3 objects by privileged users only.What should a solutions architect do to protect against data loss? (Choose two.)

A. Enable versioning on the S3 bucket.
B. Enable access logging on the S3 bucket.
C. Enable server-side encryption on the S3 bucket.
D. Configure an S3 lifecycle rule to transition objects to Amazon S3 Glacier.
E. Use MFA Delete to require multi-factor authentication to delete an object.

A. Enable versioning on the S3 bucket.
E. Use MFA Delete to require multi-factor authentication to delete an object.

An operations team has a standard that states IAM policies should not be applied directly to users. Some new members have not been following this standard.The operation manager needs a way to easily identify the users with attached policies.What should a solutions architect do to accomplish this?

A. Monitor using AWS CloudTrail.
B. Create an AWS Config rule to run daily.
C. Publish IAM user changes to Amazon SNS.
D. Run AWS Lambda when a user is modified.

B. Create an AWS Config rule to run daily.

What should a solutions architect recommend to ensure the application is able to handle the workload and avoid downtime?

This causes the CPU utilization of the EC2 instances to immediately peak to 100%, which disrupts the application. What should a solutions architect recommend to ensure the application is able to handle the workload and avoid downtime? A. Configure an Amazon CloudFront distribution in front of the ALB.

What helps users maintain application availability and allows them to automatically add or remove EC2 instances according to the conditions defined by them?

Amazon EC2 Auto Scaling helps you maintain application availability and lets you automatically add or remove EC2 instances using scaling policies that you define. Dynamic or predictive scaling policies let you add or remove EC2 instance capacity to service established or real-time demand patterns.
