A company is designing a message-driven order processing application on AWS. The application consists of many services and needs to communicate the results of its processing to multiple consuming services. Each of the consuming services may take up to 5 days to receive the messages
Which process will meet these requirements?
A. The application sends the results of its processing to an Amazon Simple Notification Service (Amazon SNS) topic Each consuming service subscribes to this SNS topic and consumes the results
B. The application sends the results of its processing to an Amazon Simple Notification Service (Amazon SNS) topic Each consuming service consumes the messages directly from its corresponding SNS topic.
C. The application sends the results of its processing to an Amazon Simple Queue Service (Amazon SQS) queue Each consuming service runs as an AWS Lambda function that consumes this single SQS queue.
D. The application sends the results of its processing to an Amazon Simple Notification Service (Amazon SNS) topic. An Amazon Simple Queue Service (Amazon SQS) queue is created for each service and each queue is configured to be a subscriber of the SNS topic.
A company stores call recordings on a monthly basis Statistically, the recorded data may be referenced randomly within a year but accessed rarely after 1 year Files that are newer than 1 year old must be queried and retrieved as quickly as possible. A delay in retrieving older files is acceptable A solutions architect needs to store the recorded data at a minimal cost Which solution is MOST cost-effective?
A. Store individual files in Amazon S3 Glacier and store search metadata in object tags created in S3 Glacier Query S3 Glacier tags and retrieve the files from S3 Glacier
B. Store individual files in Amazon S3 Use lifecycle policies to move the files to Amazon S3 Glacier after 1 year. Query and retrieve the files from Amazon S3 or S3 Glacier.
C. Archive individual files and store search metadata for each archive in Amazon S3 Use lifecycle policies to move the files to Amazon S3 Glacier after 1 year Query and retrieve the files by searching for metadata from Amazon S3
D. Archive individual files in Amazon S3 Use lifecycle policies to move the files to Amazon S3 Glacier after 1 year Store search metadata in Amazon DynamoDB Query the files from DynamoDB and retrieve them from Amazon S3 or S3 Glacier
A company has an application that runs on Amazon EC2 instances within a private subnet in a VPC The instances access data in an Amazon S3 bucket in the same AWS Region. The VPC contains a NAT gateway in a public subnet to access the S3 bucket The company wants to reduce costs by replacing the NAT gateway without compromising security or redundancy
Which solution meets these requirements?
A. Replace the NAT gateway with a NAT instance
B. Replace the NAT gateway with an internet gateway.
C. Replace the NAT gateway with a gateway VPC endpoint
D. Replace the NAT gateway with an AWS Direct Connect connection
An application uses an Amazon RDS MySQL DB instance. The RDS database is becoming low on disk space. A solutions architect wants to increase the disk space without downtime
Which solution meets these requirements with the LEAST amount of effort?
A. Enable storage auto scaling in RDS.
B. Increase the RDS database instance size
C. Change the RDS database instance storage type to Provisioned IOPS.
D. Back up the RDS database, increase the storage capacity, restore the database and stop the previous instance
A company that hosts its web application on AWS wants to ensure all Amazon EC2 instances. Amazon RDS DB instances and Amazon Redshift clusters are configured with tags. The company wants to minimize the effort of configuring and operating this check. What should a solutions architect do to accomplish this?
A. Use AWS Config rules to define and detect resources that are not property tagged
B. Use Cost Explorer to display resources that are not properly tagged Tag those resources manually.
C. Write API calls to check all resources for proper tag allocation. Periodically run the code on an EC2 instance.
D. Write API calls to check all resources for proper tag allocation. Schedule an AWS Lambda function through Amazon CloudWatch to periodically run the code
An application running on an Amazon EC2 instance needs to access an Amazon DynamoDB table Both the EC2 instance and the DynamoDB table are in the same AWS account A solutions architect must configure the necessary
permissions.
Which solution will allow least privilege access to the DynamoDB table from the EC2 instance?
A. Create an IAM role with the appropriate policy to allow access to the DynamoDB table Create an instance profile to assign this IAM role to the EC2 instance
B. Create an IAM role with the appropriate policy to allow access to the DynamoDB table Add the EC2 instance to the trust relationship policy document to allow it to assume the role
C. Create an IAM user with the appropriate policy to allow access to the DynamoDB table Store the credentials in an Amazon S3 bucket and read them from within the application code directly.
D. Create an IAM user with the appropriate policy to allow access to the DynamoDB table Ensure that the application stores the IAM credentials securely on local storage and uses them to make the DynamoDB calls
A company wants to optimize the cost of its data storage for data that is accessed quarterly. The company requires high throughput, low latency, and rapid access, when needed Which Amazon S3 storage class should a solutions architect recommend?
A. Amazon S3 Glacier (S3 Glacier)
B. Amazon S3 Standard (S3 Standard)
C. Amazon S3 Intelligent-Tiering (S3 Intelligent-Tiering)
D. Amazon S3 Standard-Infrequent Access (S3 Standard-IA)
A company requires that all versions of objects in its Amazon S3 bucket be retained Current object versions will be frequently accessed during the first 30 days, after which they will be rarely accessed and must be retrievable within 5 minutes Previous object versions need to be kept forever, will be rarely accessed, and can be retrieved within 1 week. All storage solutions must be highly available and highly durable.
What should a solutions architect recommend to meet these requirements in the MOST cost- effective manner?
A. Create an S3 lifecycle policy for the bucket that moves current object versions from S3 Standard storage to S3 Glacier after 30 days and moves previous object versions to S3 Glacier after 1 day.
B. Create an S3 lifecycle policy for the bucket that moves current object versions from S3 Standard storage to S3 Glacier after 30 days and moves previous object versions to S3 Glacier Deep Archive after 1 day
C. Create an S3 lifecycle policy for the bucket that moves current object versions from S3 Standard storage to S3 Standard-infrequent Access (S3 Standard-IA) after 30 days and moves previous object versions to S3 Glacier Deep Archive after 1 day
D. Create an S3 lifecycle policy for the bucket that moves current object versions from S3 Standard storage to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 30 days and moves previous object versions to S3 Glacier Deep Archive after 1 day
An application allows users at a company's headquarters to access product data The product data is stored in an Amazon RDS MySQL DB instance. The operations team has isolated an application performance slowdown and wants to separate read traffic from write traffic. A solutions architect needs to optimize the application's performance quickly.
What should the solutions architect recommend?
A. Change the existing database to a Multi-AZ deployment Serve the read requests from the primary Availability Zone
B. Change the existing database to a Multi-AZ deployment Serve the read requests from the secondary Availability Zone
C. Create read replicas for the database Configure the read replicas with half of the compute and storage resources as the source database
D. Create read replicas for the database Configure the read replicas with the same compute and storage resources as the source database
A solutions architect is using Amazon S3 to design the storage architecture of a new digital media application. The media files must be resilient to the loss of an Availability Zone Some files are accessed frequently while other files are rarely
accessed in an unpredictable pattern. The solutions architect must minimize the costs of storing and retrieving the media files.
Which storage option meets these requirements?
A. S3 Standard
B. S3 Intelligent-Tiering
C. S3 Standard-Infrequent Access {S3 Standard-IA)
D. S3 One Zone-Infrequent Access (S3 One Zone-IA)
