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

Question 57

A company has an on-premises application that uses SFTP to collect financial data from multiple vendors. The company is migrating to the AWS Cloud. The company has created an application that uses Amazon S3 APIs to upload files from vendors.

Some vendors run their systems on legacy applications that do not support S3 APIs. The vendors want to continue to use SFTP-based applications to upload data. The company wants to use managed services for the needs of the vendors that use legacy applications.

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

Options:

A.

Create an AWS Database Migration Service (AWS DMS) instance to replicate data from the storage of the vendors that use legacy applications to Amazon S3. Provide the vendors with the credentials to access the AWS DMS instance.

B.

Create an AWS Transfer Family endpoint for vendors that use legacy applications.

C.

Configure an Amazon EC2 instance to run an SFTP server. Instruct the vendors that use legacy applications to use the SFTP server to upload data.

D.

Configure an Amazon S3 File Gateway for vendors that use legacy applications to upload files to an SMB file share.

Question 58

A company wants to relocate its on-premises MySQL database to AWS. The database accepts regular imports from a client-facing application, which causes a high volume of write operations. The company is concerned that the amount of traffic might be causing performance issues within the application.

Options:

A.

Provision an Amazon RDS for MySQL DB instance with Provisioned IOPS SSD storage. Monitor write operation metrics by using Amazon CloudWatch. Adjust the provisioned IOPS if necessary.

B.

Provision an Amazon RDS for MySQL DB instance with General Purpose SSD storage. Place an Amazon ElastiCache cluster in front of the DB instance. Configure the application to query ElastiCache instead.

C.

Provision an Amazon DocumentDB (with MongoDB compatibility) instance with a memory-optimized instance type. Monitor Amazon CloudWatch for performance-related issues. Change the instance class if necessary.

D.

Provision an Amazon Elastic File System (Amazon EFS) file system in General Purpose performance mode. Monitor Amazon CloudWatch for IOPS bottlenecks. Change to Provisioned Throughput performance mode if necessary.

Question 59

A company has 5 TB of datasets. The datasets consist of 1 million user profiles and 10 million connections. The user profiles have connections as many-to-many relationships. The company needs a performance-efficient way to find mutual connections up to five levels.

Which solution will meet these requirements?

Options:

A.

Use an Amazon S3 bucket to store the datasets. Use Amazon Athena to perform SQL JOIN queries to find connections.

B.

Use Amazon Neptune to store the datasets with edges and vertices. Query the data to find connections.

C.

Use an Amazon S3 bucket to store the datasets. Use Amazon QuickSight to visualize connections.

D.

Use Amazon RDS to store the datasets with multiple tables. Perform SQL JOIN queries to find connections.

Question 60

A media company hosts its video processing workload on AWS. The workload uses Amazon EC2 instances in an Auto Scaling group to handle varying levels of demand. The workload stores the original videos and the processed videos in an Amazon S3 bucket.

The company wants to ensure that the video processing workload is scalable. The company wants to prevent failed processing attempts because of resource constraints. The architecturemust be able to handle sudden spikes in video uploads without impacting the processing capability.

Which solution will meet these requirements with the LEAST overhead?

Options:

A.

Migrate the workload from Amazon EC2 instances to AWS Lambda functions. Configure an Amazon S3 event notification to invoke the Lambda functions when a new video is uploaded. Configure the Lambda functions to process videos directly and to save processed videos back to the S3 bucket.

B.

Migrate the workload from Amazon EC2 instances to AWS Lambda functions. Use Amazon S3 to invoke an Amazon Simple Notification Service (Amazon SNS) topic when a new video is uploaded. Subscribe the Lambda functions to the SNS topic. Configure the Lambda functions to process the videos asynchronously and to save processed videos back to the S3 bucket.

C.

Configure an Amazon S3 event notification to send a message to an Amazon Simple Queue Service (Amazon SQS) queue when a new video is uploaded. Configure the existing Auto Scaling group to poll the SQS queue, process the videos, and save processed videos back to the S3 bucket.

D.

Configure an Amazon S3 upload trigger to invoke an AWS Step Functions state machine when a new video is uploaded. Configure the state machine to orchestrate the video processing workflow by placing a job message in the Amazon SQS queue. Configure the job message to invoke the EC2 instances to process the videos. Save processed videos back to the S3 bucket.
