A company runs a three-tier ecommerce application on EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). Data is stored in an Amazon RDS for MariaDB Multi-AZ DB instance. The company wants durable customer session management during transactions. Which solutions meet this requirement? (Choose two.)

For durable customer session management, sticky sessions on the ALB ensure that a user's requests are consistently routed to the same EC2 instance. This maintains session state stored locally on that instance. Alternatively, using an Amazon ElastiCache for Redis cluster provides an external, highly available, and scalable data store for session information, making sessions durable even if an EC2 instance fails or scales. Using an Amazon DynamoDB table is a valid option for session storage but is not listed as a correct answer here. Amazon Cognito is for user authentication and authorization, not for general application session management. AWS Systems Manager Application Manager is for operational insights and management, not for storing session data.
