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

Question 141

A company is planning to run an AI/ML workload on AWS. The company needs to train a model on a dataset that is in Amazon S3 Standard. A model training application requires multiple compute nodes and single-digit millisecond access to the data.

Which solution will meet these requirements in the MOST cost-effective way?

Options:

A.

Move the data to S3 Intelligent-Tiering. Point the model training application to S3 Intelligent-Tiering as the data source.

B.

Add partitions to the S3 bucket by adding random prefixes. Reconfigure the model training application to point to the new prefixes as the data source.

C.

Move the data to S3 Express One Zone. Point the model training application to S3 Express One Zone as the data source.

D.

Move the data to a General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS)volume attached to an Amazon EC2 instance. Point the model training application to the gp3 volume as the data source.

Question 142

A company stores data for multiple business units in a single Amazon S3 bucket that is in the company's payer AWS account. To maintain data isolation, the business units store data in separate prefixes in the S3 bucket by using an S3 bucket policy.

The company plans to add a large number of dynamic prefixes. The company does not want to rely on a single S3 bucket policy to manage data access at scale. The company wants to develop a secure access management solution in addition to the bucket policy to enforce prefix-level data isolation.

Options:

A.

Configure the S3 bucket policy to deny s3:GetObject permissions for all users. Configure the bucket policy to allow s3:* access to individual business units.

B.

Enable default encryption on the S3 bucket by using server-side encryption with Amazon S3 managed keys (SSE-S3).

C.

Configure resource-based permissions on the S3 bucket by creating an S3 access point for each business unit.

D.

Use pre-signed URLs to provide access to the S3 bucket.

Question 143

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 must offer backups.

Which solution will meet these requirements MOST cost-effectively?

Options:

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.

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.

C.

Host the visualization tool on premises. Connect to the data warehouse through the Direct Connect connection.
