AWS Certified Solutions Architect - Associate SAA-C03
A company collects data for temperature, humidity, and atmospheric pressure in cities across multiple continents. The average volume of data
that the company collects from each site daily is 500 GB. Each site has a high-speed Internet connection.
The company wants to aggregate the data from all these global sites as quickly as possible in a single Amazon S3 bucket. The solution must
minimize operational complexity.
Which solution meets these requirements?
Turn on S3 Transfer Acceleration on the destination S3 bucket. Use multipart uploads to directly upload site data to the destination S3
bucket. Most Voted
Upload the data from each site to an S3 bucket in the closest Region. Use S3 Cross-Region Replication to copy objects to the destination S3
bucket. Then remove the data from the origin S3 bucket.
Schedule AWS Snowball Edge Storage Optimized device jobs daily to transfer data from each site to the closest Region. Use S3 Cross-
Region Replication to copy objects to the destination S3 bucket.
Upload the data from each site to an Amazon EC2 instance in the closest Region. Store the data in an Amazon Elastic Block Store (Amazon
EBS) volume. At regular intervals, take an EBS snapshot and copy it to the Region that contains the destination S3 bucket. Restore the EBS
volume in that Region.
A company needs the ability to analyze the log files of its proprietary application. The logs are stored in JSON format in an Amazon S3 bucket.
Queries will be simple and will run on-demand. A solutions architect needs to perform the analysis with minimal changes to the existing
architecture.
What should the solutions architect do to meet these requirements with the LEAST amount of operational overhead?
Use Amazon Redshift to load all the content into one place and run the SQL queries as needed.
Use Amazon CloudWatch Logs to store the logs. Run SQL queries as needed from the Amazon CloudWatch console.
Use Amazon Athena directly with Amazon S3 to run the queries as needed. Most Voted
Use AWS Glue to catalog the logs. Use a transient Apache Spark cluster on Amazon EMR to run the SQL queries as needed.
A company uses AWS Organizations to manage multiple AWS accounts for different departments. The management account has an Amazon S3
bucket that contains project reports. The company wants to limit access to this S3 bucket to only users of accounts within the organization in
AWS Organizations.
Which solution meets these requirements with the LEAST amount of operational overhead?
Add the aws PrincipalOrgID global condition key with a reference to the organization ID to the S3 bucket policy. Most Voted
Create an organizational unit (OU) for each department. Add the aws:PrincipalOrgPaths global condition key to the S3 bucket policy.
Use AWS CloudTrail to monitor the CreateAccount, InviteAccountToOrganization, LeaveOrganization, and RemoveAccountFromOrganization
events. Update the S3 bucket policy accordingly.
Tag each user that needs access to the S3 bucket. Add the aws:PrincipalTag global condition key to the S3 bucket policy.
An application runs on an Amazon EC2 instance in a VPC. The application processes logs that are stored in an Amazon S3 bucket. The EC2
instance needs to access the S3 bucket without connectivity to the internet.
Which solution will provide private network connectivity to Amazon S3?
Create a gateway VPC endpoint to the S3 bucket. Most Voted
Stream the logs to Amazon CloudWatch Logs. Export the logs to the S3 bucket.
Create an instance profile on Amazon EC2 to allow S3 access.
Create an Amazon API Gateway API with a private link to access the S3 endpoint.
A company is hosting a web application on AWS using a single Amazon EC2 instance that stores user-uploaded documents in an Amazon EBS
volume. For better scalability and availability, the company duplicated the architecture and created a second EC2 instance and EBS volume in
another Availability Zone, placing both behind an Application Load Balancer. After completing this change, users reported that, each time they
refreshed the website, they could see one subset of their documents or the other, but never all of the documents at the same time.
What should a solutions architect propose to ensure users see all of their documents at once?
Copy the data so both EBS volumes contain all the documents
Configure the Application Load Balancer to direct a user to the server with the documents
Copy the data from both EBS volumes to Amazon EFS. Modify the application to save new documents to Amazon EFS Most Voted
Configure the Application Load Balancer to send the request to both servers. Return each document from the correct server
