Solutions Architect Professional (Page 97)

A company recently deployed an application on AWS.The application uses Amazon DynamoDB.The company measured the application load and configured the RCUs and WCUs on the DynamoDB table to match the expected peak load.The peak load occurs once a week for a 4-hour period and is double the average load.The application load is close to the average load for the rest of the week.The access pattern includes many more writes to the table than reads of the table.A solutions architect needs to implement a solution to minimize the cost of the table.Which solution will meet these requirements?Read More →

A company is using AWS CodePipeline for the CI/CD of an application to an Amazon EC2 Auto Scaling group.All AWS resources are defined in AWS CloudFormation templates.The application artifacts are stored in an Amazon S3 bucket and deployed to the Auto Scaling group using instance user data scripts.As the application has become more complex, recent resource changes in the CloudFormation templates have caused unplanned downtime.How should a solutions architect improve the CI/CD pipeline to reduce the likelihood that changes in the templates will cause downtime?Read More →

A solutions architect has been assigned to migrate a 50 TB Oracle data warehouse that contains sales data from on-premises to Amazon Redshift.Major updates to the sales data occur on the final calendar day of the month.For the remainder of the month, the data warehouse only receives minor daily updates and is primarily used for reading and reporting.Because of this, the migration process must start on the first day of the month and must be complete before the next set of updates occur.This provides approximately 30 days to complete the migration and ensure that the minor daily changes have been synchronized with theAmazon Redshift data warehouse.Because the migration cannot impact normal business network operations, the bandwidth allocated to the migration for moving data over the internet is 50 Mbps.The company wants to keep data migration costs low.Which steps will allow the solutions architect to perform the migration within the specified timeline?Read More →

A scientific company needs to process text and image data from an Amazon S3 bucket.The data is collected from several radar stations during a live, time-critical phase of a deep space mission.The radar stations upload the data to the source S3 bucket.The data is prefixed by radar station identification number.The company created a destination S3 bucket in a second account.Data must be copied from the source S3 bucket to the destination S3 bucket to meet a compliance objective.This replication occurs through the use of an S3 replication rule to cover all objects in the source S3 bucket.One specific radar station is identified as having the most accurate data.Data replication at this radar station must be monitored for completion within 30 minutes after the radar station uploads the objects to the source S3 bucket.What should a solutions architect do to meet these requirements?Read More →

A company has a primary Amazon S3 bucket that receives thousands of objects every day.The company needs to replicate these objects into several other S3 buckets from various AWS accounts.A solutions architect is designing a new AWS Lambda function that is triggered when an object is created in the main bucket and replicates the object into the target buckets.The objects do not need to be replicated in real time.There is concern that this function may impact other criticalLambda functions due to Lambda’s regional concurrency limit.How can the solutions architect ensure this new Lambda function will not impact other critical Lambda functions?Read More →

A solutions architect is reviewing an application’s resilience before launch.The application runs on an Amazon EC2 instance that is deployed in a private subnet of a VPC.The EC2 instance is provisioned by an Auto Scaling group that has a minimum capacity of 1 and a maximum capacity of 1.The application stores data on an Amazon RDS for MySQL DB instance.The VPC has subnets configured in three Availability Zones and is configured with a single NAT gateway.The solutions architect needs to recommend a solution to ensure that the application will operate across multiple Availability Zones.Which solution will meet this requirement?Read More →

A company uses AWS Organizations to manage one parent account and nine member accounts.The number of member accounts is expected to grow as the business grows.A security engineer has requested consolidation of AWS CloudTrail logs into the parent account for compliance purposes.Existing logs currently stored in Amazon S3 buckets in each individual member account should not be lost.Future member accounts should comply with the logging strategy.Which operationally efficient solution meets these requirements?Read More →

A company is planning to migrate an Amazon RDS for Oracle database to an RDS for PostgreSQL DB instance in another AWS account.A solutions architect needs to design a migration strategy that will require no downtime and that will minimize the amount of time necessary to complete the migration.The migration strategy must replicate all existing data and any new data that is created during the migration.The target database must be identical to the source database at completion of the migration process.All applications currently use an Amazon Route 53 CNAME record as their endpoint for communication with the RDS for Oracle DB instance.The RDS for Oracle DB instance is in a private subnet.Which combination of steps should the solutions architect take to meet these requirements? (Choose three.)Read More →

A company wants to migrate an application to Amazon EC2 from VMware Infrastructure that runs in an on-premises data center.A solutions architect must preserve the software and configuration settings during the migration.What should the solutions architect do to meet these requirements?Read More →

A large company recently experienced an unexpected increase in Amazon RDS and Amazon DynamoDB costs.The company needs to increase visibility into details of AWS Billing and Cost Management.There are various accounts associated with AWS Organizations, including many development and production accounts.There is no consistent tagging strategy across the organization, but there are guidelines in place that require all infrastructure to be deployed using AWS CloudFormation with consistent tagging.Management requires cost center numbers and project ID numbers for all existing and future DynamoDB tables and RDS instances.Which strategy should the solutions architect provide to meet these requirements?Read More →
