1. A solutions architect is evaluating the reliability of a recently migrated application running on AWS. The front end is hosted on Amazon S3 and accelerated by Amazon CloudFront. The application layer is running in a stateless Docker container on an Amazon EC2 On-Demand Instance with an Elastic IP address. The storage layer is a MongoDB database running on an EC2 Reserved Instance in the same Availability Zone as the application layer.

Which combination of steps should the solutions architect take to eliminate single points of failure with minimal application code changes? (Select TWO.)

A. Create a REST API in Amazon API Gateway and use AWS Lambda functions as the application layer.

B. Create an Application Load Balancer and migrate the Docker container to AWS Fargate.

C. Migrate the storage layer to Amazon DynamoD8.

D. Migrate the storage layer to Amazon DocumentD8 (with MongoDB compatibility).

E. Create an Application Load Balancer and move the storage layer to an EC2 Auto Scaling group.

Answer: B,D

2. A solutions architect is building a web application that uses an Amazon RDS for PostgreSQL DB instance. The DB instance is expected to receive many more reads than writes. The solutions architect needs to ensure that the large amount of read traffic can be accommodated and that the DB instance is highly available.

Which steps should the solutions architect take to meet these requirements? (Select THREE)

A. Create multiple read replicas and put them into an Auto Scaling group.

B. Create multiple read replicas in different Availability Zones.

C. Create an Amazon Route 53 hosted zone and a record set for each read replica with a TTL and a weighted routing policy.

D. Create an Application Load Balancer (ALB) and put the read replicas behind the ALB.

E. Configure an Amazon CloudWatch alarm to detect a failed read replica. Set the alarm to directly invoke an AWS Lambda function to delete its Route 53 record set.

F. Configure an Amazon Route 53 health check for each read replica using its endpoint

Answer: B,C,F

3. A company's AWS architecture currently uses access keys and secret access keys stored on each instance to access AWS services. Database credentials are hard-coded on each instance. SSH keys for command-tine remote access are stored in a secured Amazon S3 bucket. The company has asked its solutions architect to improve the security posture of the architecture without adding operational complexity.

Which combination of steps should the solutions architect take to accomplish this? (Select THREE.)

A. Use Amazon EC2 instance profiles with an IAM role.

B. Use AWS Secrets Manager to store access keys and secret access keys.

C. Use AWS Systems Manager Parameter Store to store database credentials.

D. Use a secure fleet of Amazon EC2 bastion hosts (or remote access.

E. Use AWS KMS to store database credentials.

F. Use AWS Systems Manager Session Manager tor remote access

Answer: A,C,F

4. A developer reports receiving an Error 403: Access Denied message when they try to download an object from an Amazon S3 bucket. The S3 bucket is accessed using an S3 endpoint inside a VPC. and is encrypted with an AWS KMS key. A solutions architect has verified that (he developer is assuming the correct IAM role in the account that allows the object to be downloaded. The S3 bucket policy and the NACL are also valid.

Which additional step should the solutions architect take to troubleshoot this issue?

A. Ensure that blocking all public access has not been enabled in the S3 bucket.

B. Verify that the IAM rote has permission to decrypt the referenced KMS key.

C. Verify that the IAM role has the correct trust relationship configured.

D. Check that local firewall rules are not preventing access to the S3 endpoint.

Answer: B

5. A solutions architect is designing a publicly accessible web application that is on an Amazon CloudFront distribution with an Amazon S3 website endpoint as the origin. When the solution is deployed, the website returns an Error 403: Access Denied message.

Which steps should the solutions architect take to correct the issue? (Select TWO.)

A. Remove the S3 block public access option from the S3 bucket.

B. Remove the requester pays option trom the S3 bucket.

C. Remove the origin access identity (OAI) from the CloudFront distribution.

D. Change the storage class from S3 Standard to S3 One Zone-Infrequent Access (S3 One Zone-IA).

E. Disable S3 object versioning.

Answer: A,B

6. A company requires that all internal application connectivity use private IP addresses. To facilitate this policy, a solutions architect has created interface endpoints to connect to AWS public services. Upon testing, the solutions architect notices that the service names are resolving to public IP addresses, and that internal services cannot connect to the interface endpoints.

Which step should the solutions architect take to resolve this issue?

A. Update the subnet route table with a route to the interface endpoint.

B. Enable the private DNS option on the VPC attributes.

C. Configure the security group on the interface endpoint to allow connectivity to the AWS services.

D. Configure an Amazon Route 53 private hosted zone with a conditional forwarder for the internal application.

Answer: C
