A solutions architect is designing the architecture of a new application being deployed to the AWS Cloud. The application will run on Amazon EC2 On-Demand Instances and will automatically scale across multiple Availability Zones. The EC2 instances will scale up and down frequently throughout the day. An Application Load Balancer (ALB) will handle the load distribution. The architecture needs to support distributed session data management. The company is willing to make changes to code if needed.

What should the solutions architect do to ensure that the architecture supports distributed session data management?

  1. Use Amazon ElastiCache to manage and store session data.
  2. Use session affinity (sticky sessions) of the ALB to manage session data.
  3. Use Session Manager from AWS Systems Manager to manage the session.
  4. Use the GetSessionToken API operation in AWS Security Token Service (AWS STS) to manage the session.

Answer(s): A



A company offers a food delivery service that is growing rapidly. Because of the growth, the company’s order processing system is experiencing scaling problems during peak traffic hours. The current architecture includes the following:

-A group of Amazon EC2 instances that run in an Amazon EC2 Auto Scaling group to collect orders from the application
-Another group of EC2 instances that run in an Amazon EC2 Auto Scaling group to fulfill orders

The order collection process occurs quickly, but the order fulfillment process can take longer. Data must not be lost because of a scaling event.

A solutions architect must ensure that the order collection process and the order fulfillment process can both scale properly during peak traffic hours. The solution must optimize utilization of the company’s AWS resources.

Which solution meets these requirements?

  1. Use Amazon CloudWatch metrics to monitor the CPU of each instance in the Auto Scaling groups. Configure each Auto Scaling group’s minimum capacity according to peak workload values.
  2. Use Amazon CloudWatch metrics to monitor the CPU of each instance in the Auto Scaling groups. Configure a CloudWatch alarm to invoke an Amazon Simple Notification Service (Amazon SNS) topic that creates additional Auto Scaling groups on demand.
  3. Provision two Amazon Simple Queue Service (Amazon SQS) queues: one for order collection and another for order fulfillment. Configure the EC2 instances to poll their respective queue. Scale the Auto Scaling groups based on notifications that the queues send.
  4. Provision two Amazon Simple Queue Service (Amazon SQS) queues: one for order collection and another for order fulfillment. Configure the EC2 instances to poll their respective queue. Create a metric based on a backlog per instance calculation. Scale the Auto Scaling groups based on this metric.

Answer(s): D



A company hosts multiple production applications. One of the applications consists of resources from Amazon EC2, AWS Lambda, Amazon RDS, Amazon Simple Notification Service (Amazon SNS), and Amazon Simple Queue Service (Amazon SQS) across multiple AWS Regions. All company resources are tagged with a tag name of “application” and a value that corresponds to each application. A solutions architect must provide the quickest solution for identifying all of the tagged components.

Which solution meets these requirements?

  1. Use AWS CloudTrail to generate a list of resources with the application tag.
  2. Use the AWS CLI to query each service across all Regions to report the tagged components.
  3. Run a query in Amazon CloudWatch Logs Insights to report on the components with the application tag.
  4. Run a query with the AWS Resource Groups Tag Editor to report on the resources globally with the application tag.

Answer(s): D



A company needs to export its database once a day to Amazon S3 for other teams to access. The exported object size varies between 2 GB and 5 GB. The S3 access pattern for the data is variable and changes rapidly. The data must be immediately available and must remain accessible for up to 3 months. The company needs the most cost-effective solution that will not increase retrieval time.

Which S3 storage class should the company use to meet these requirements?

  1. S3 Intelligent-Tiering
  2. S3 Glacier Instant Retrieval
  3. S3 Standard
  4. S3 Standard-Infrequent Access (S3 Standard-IA)

Answer(s): A
