Question 1

A company is launching a new application that requires a structured database to store user profiles,application settings, and transactional data. The database must be scalable with application traffic and mustoffer backups.Which solution will meet these requirements MOST cost-effectively?

A : Deploy a self-managed database on Amazon EC2 instances by using open-source software. Use Spot Instances for cost optimization. Configure automated backups to Amazon S3.

B : Use Amazon RDS. Use on-demand capacity mode for the database with General Purpose SSD storage. Configure automatic backups with a retention period of 7 days.

C : Use Amazon Aurora Serverless for the database. Use serverless capacity scaling. Configure automated backups to Amazon S3.

D : Deploy a self-managed NoSQL database on Amazon EC2 instances. Use Reserved Instances for cost optimization. Configure automated backups directly to Amazon S3 Glacier Flexible Retrieval.

Answer: C

Question 2

A company has a license-based, expensive, legacy commercial database solution deployed at its on-premises data center. The company wants to migrate this database to a more efficient, open-source, and cost-effective option on AWS Cloud. The CTO at the company wants a solution that can handle complex database configurations such as secondary indexes, foreign keys, and stored procedures.

As a solutions architect, which of the following AWS services should be combined to handle this use-case? (Select two)

A : AWS Snowball Edge

B : AWS Glue

C : AWS Database Migration Service (AWS DMS)

D : Basic Schema Copy

E : AWS Schema Conversion Tool (AWS SCT)

Answer: C,E

Question 3

A company runs a Java-based job on an Amazon EC2 instance. The job runs every hour and takes 10 seconds to run. The job runs on a scheduled interval and consumes 1 GB of memory. The CPU utilization of the instance is low except for short surges during which the job uses the maximum CPU available. The company wants to optimize the costs to run the job.

A : Use AWS App2Container (A2C) to containerize the job. Run the job as an Amazon Elastic Container Service (Amazon ECS) task on AWS Fargate with 0.5 virtual CPU (vCPU) and 1 GB of memory.

B : Copy the code into an AWS Lambda function that has 1 GB of memory. Create an Amazon EventBridge scheduled rule to run the code each hour.

C : Use AWS App2Container (A2C) to containerize the job. Install the container in the existing Amazon Machine Image (AMI). Ensure that the schedule stops the container when the task finishes.

D : Configure the existing schedule to stop the EC2 instance at the completion of the job and restart the EC2 instance when the next job starts.

Answer: B

Question 4

The customers of a finance company request appointments with financial advisors by sending text messages.A web application that runs on Amazon EC2 instances accepts the appointment requests. The text messagesare published to an Amazon Simple Queue Service (Amazon SQS) queue through the web application.Another application that runs on EC2 instances then sends meeting invitations and meeting confirmationemail messages to the customers. After successful scheduling, this application stores the meeting informationin an Amazon DynamoDB database.As the company expands, customers report that their meeting invitations are taking longer to arrive.What should a solutions architect recommend to resolve this issue?

A : Add a DynamoDB Accelerator (DAX) cluster in front of the DynamoDB database.

B : Add an Amazon API Gateway API in front of the web application that accepts the appointment requests.

C : Add an Amazon CloudFront distribution. Set the origin as the web application that accepts the appointment requests.

D : Add an Auto Scaling group for the application that sends meeting invitations. Configure the Auto Scaling group to scale based on the depth of the SQS queue.

Answer: D

Question 5

A company runs an application on Amazon EC2 instances. The instances need to access an Amazon RDS database by using specific credentials. The company uses AWS Secrets Manager to contain the credentials the EC2 instances must use. Which solution will meet this requirement?

A : Create an IAM role, and attach the role to each EC2 instance profile. Use an identity-based policy to grant the new IAM role access to the secret that contains the database credentials.

B : Create an IAM user, and attach the user to each EC2 instance profile. Use a resource-based policy to grant the new IAM user access to the secret that contains the database credentials.

C : Create a resource-based policy for the secret that contains the database credentials. Use EC2 Instance Connect to access the secret.

D : Create an identity-based policy for the secret that contains the database credentials. Grant direct access to the EC2 instances.

Answer: A
