AWS Certified Solutions Architect - Associate (SAA-C03) Questions and Answers

Question 69

A company has a three-tier web application. An Application Load Balancer (ALB) is in front of Amazon EC2 instances that are in the ALB target group. An Amazon S3 bucket stores documents.

The company requires the application to meet a recovery time objective (RTO) of 60 seconds.

Which solution will meet this requirement?

Options:

A.

Replicate S3 objects to a second AWS Region. Create a second ALB and a minimum set of EC2 instances in the second Region. Ensure that the EC2 instances are shut down until they are needed. Configure Amazon Route 53 to fail over to the second Region by using an IP-based routing policy.

B.

Use AWS Backup to take hourly backups of the EC2 instances. Back up the S3 data to a second AWS Region. Use AWS CloudFormation to deploy the entire infrastructure in the second Region when needed.

C.

Create daily snapshots of the EC2 instances in a second AWS Region. Use the snapshots to recreate the instances in the second Region. Back up the S3 data to the second Region. Perform a failover by modifying the application DNS record when needed.

D.

Replicate S3 objects to a second AWS Region. Create a second ALB and a minimum set of EC2 instances in the second Region. Ensure that the EC2 instances in the second Region are running. Configure Amazon Route 53 to fail over to the secondary Region based on health checks.

Question 70

A company has developed an API by using an Amazon API Gateway REST API and AWS Lambda functions. The API serves static content and dynamic content to users worldwide. The company wants to decrease the latency of transferring the content for API requests. Which solution will meet these requirements?

Deploy the REST API as an edge-optimized API endpoint. Enable caching. Enable content encoding in the API definition to compress the application data in transit.

B.

Deploy the REST API as a Regional API endpoint. Enable caching. Enable content encoding in the API definition to compress the application data in transit.

Question 71

A company stores sensitive financial reports in an Amazon S3 bucket. To comply with auditing requirements, the company must encrypt the data at rest. Users must not have the ability to change the encryption method or remove encryption when the users upload data. The company must be able to audit all encryption and storage actions. Which solution will meet these requirements and provide the MOST granular control?

Options:

A.

Enable default server-side encryption with Amazon S3 managed keys (SSE-S3) for the S3 bucket. Apply a bucket policy that denies any upload requests that do not include the x-amz-server-side-encryption header.

B.

Configure server-side encryption with AWS KMS (SSE-KMS) keys. Use an S3 bucket policy to reject any data that is not encrypted by the designated key.

C.

Use client-side encryption before uploading the reports. Store the encryption keys in AWS Secrets Manager.

D.

Enable default server-side encryption with Amazon S3 managed keys (SSE-S3). Use AWS Identity and Access Management (IAM) to prevent users from changing S3 bucket settings.

Question 72

The result sets that the data warehouse returns are not cached.

The company wants to optimize costs for data transfers between the data warehouse and the company.

Which solution will meet this requirement?

Options:

A.

Host the visualization tool on premises. Connect to the data warehouse directly through the internet.

B.

Host the visualization tool in the same AWS Region as the data warehouse. Access the visualization tool through the internet.
