Out of the striping options available for the EBS volumes, which one has the following disadvantage:’Doubles the amount of I/O required from the instance to EBS compared to RAID 0, because you’re mirroring all writes to a pair of volumes, limiting how much you can stripe.’?Read More →

A solutions architect needs to deploy an application on a fleet of Amazon EC2 Instances.The EC2 instances run in private subnets in an Auto Scaling group.The application is expected to generate logs at a rate of 100 MB each second on each of the EC2 instances.The logs must be stored in an Amazon S3 bucket so that an Amazon EMR cluster can consume them for further processing.The logs must be quickly accessible for the first 90 days and should be retrievable within 48 hours thereafter.What is the MOST cost-effective solution that meets these requirements?Read More →

A solutions architect is building a web application that uses an Amazon RDS for PostgreSQL DB instance.The DB instance is expected to receive many more reads than writes.The solutions architect needs to ensure that the large amount of read traffic can be accommodated and that the DB instance is highly available.Which steps should the solutions architect take to meet these requirements? (Choose three.)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 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 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 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 that tracks medical devices in hospitals wants to migrate its existing storage solution to the AWS Cloud.The company equips all of its devices with sensors that collect location and usage information.This sensor data is sent in unpredictable patterns with large spikes.The data is stored in a MySQL database running on premises at each hospital.The company wants the cloud storage solution to scale with usage.The company’s analytics team uses the sensor data to calculate usage by device type and hospital.The team needs to keep analysis tools running locally while fetching data from the cloud.The team also needs to use existing Java application and SQL queries with as few changes as possible.How should a solutions architect meet these requirements while ensuring the sensor data is secure?Read More →
