AWS Certified Solutions Architect - Professional Questions and Answers

Question 1

A company is planning a large event where a promotional offer will be introduced. The company's website is hosted on AWS and backed by an Amazon RDS for PostgreSQL DB instance. The website explains the promotion and includes a sign-up page that collects user information andpreferences. Management expects large and unpredictable volumes of traffic periodically, which will create many database writes. A solutions architect needs to build a solution that does not change the underlying data model and ensures that submissions are not dropped before they are committed to the database.

Which solutions meets these requirements?

Options:

A.

Immediately before the event, scale up the existing DB instance to meet the anticipated demand. Then scale down after the event.

B.

Use Amazon SQS to decouple the application and database layers. Configure an AWS Lambda function to write items from the queue into the database.

C.

Migrate to Amazon DynamoDB and manage throughput capacity with automatic scaling.

D.

Use Amazon ElastiCache (Memcached) to increase write capacity to the DB instance.

Question 2

A company uses AWS Organizations to manage a multi-account structure. The company has hundreds of AWS accounts and expects the number of accounts to increase. The company is building a new application that uses Docker images. The company will push the Docker images to Amazon Elastic Container Registry (Amazon ECR). Only accounts that are within the company's organization should have

access to the images.

The company has a CI/CD process that runs frequently. The company wants to retain all the tagged images. However, the company wants to retain only the five most recent untagged images.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

A.

Create a private repository in Amazon ECR. Create a permissions policy for the repository that allows only required ECR operations. Include a condition to allow the ECR operations if the value of the aws:PrincipalOrglD condition key is equal to the ID of the company's organization. Add a lifecycle rule to the ECR repository that deletes all untagged images over the count of five.

B.

Create a public repository in Amazon ECR. Create an IAM role in the ECR account. Set permissions so that any account can assume the role if the value of the aws:PrincipalOrglD condition key is equal to the ID of the company's organization. Add a lifecycle rule to the ECR repository that deletes all untagged images over the count of five.

C.

Create a private repository in Amazon ECR. Create a permissions policy for the repository that includes only required ECR operations. Include a condition to allow the ECR operations for all account IDs in the organization. Schedule a daily Amazon EventBridge rule to invoke an AWS Lambda function that deletes all untagged images over the count of five.

D.

Create a public repository in Amazon ECR. Configure Amazon ECR to use an interface VPC endpoint with an endpoint policy that includes the required permissions for images that the company needs to pull. Include a condition to allow the ECR operations for all account IDs in the company's organization. Schedule a daily Amazon EventBridge rule to invoke an AWS Lambda function that deletes all untagged images over the count of five.

Question 3

A company is running an application in the AWS Cloud. Recent application metrics show inconsistent response times and a significant increase in error rates. Calls to third-party services are causing the delays. Currently, the application calls third-party services synchronously by directly invoking an AWS Lambda function.

A solutions architect needs to decouple the third-party service calls and ensure that all the calls are eventually completed.

Question 22

A company has a website that serves many visitors. The company deploys a backend service for the website in a primary AWS Region and a disaster recovery (DR) Region.

A single Amazon CloudFront distribution is deployed for the website. The company creates an Amazon Route 53 record set with health checks and a failover routing policy for the primary Region's backend service. The company configures the Route 53 record set as an origin for the CloudFront distribution. The company configures another record set that points to the backend service's endpoint in the DR Region as a secondary failover record type. The TTL for both record sets is 60 seconds.

Question 60

An international delivery company hosts a delivery management system on AWS. Drivers use the system to upload confirmation of delivery. Confirmation includes the recipient's signature or a photo of the package with the recipient. The driver's handheld device uploads signatures and photos through FTP to a single Amazon EC2 instance. Each handheld device saves a file in a directory based on the signed-in user, and the file name matches the delivery number. The EC2 instance then adds metadata to the file after querying a central database to pull delivery information. The file is then placed in Amazon S3 for archiving.

As the company expands, drivers report that the system is rejecting connections. The FTP server is having problems because of dropped connections and memory issues. In response to these problems, a system engineer schedules a cron task to reboot the EC2 instance every 30 minutes. The billing team reports that files are not always in the archive and that the central system is not always updated.
