A company is migrating a web application from on premises to AWS. The company needs to move session storage from the application code to a shared service as part of the migration. The session storage data must be encrypted at rest. Which AWS services meet these requirements? (Choose two.)

Amazon ElastiCache for Memcached

A developer is creating a Java application that will store sensitive data in an Amazon DynamoDB table. The data must be encrypted at all times. How can the developer meet this requirement?

Implement client-side encryption in the application code by using the DynamoDB Encryption Client.

Enable encryption at rest by using an AWS Key Management Service (AWS KMS) AWS owned key for the DynamoDB table.

Enable encryption at rest by using an AWS Key Management Service (AWS KMS) customer managed key for the DynamoDB table.

Implement client-side encryption in the application code by using the DynamoDB Encryption Client.

Use an HTTPS connection to encrypt data in transit.

A company that manages movie reviews wants to make its movie review data available to its customers by calling a set of REST web service endpoints. The company will develop the retrieval functionality as AWS Lambda functions and will expose the functionality to customers as an Amazon API Gateway REST API.The company needs to ensure that no consumer exceeds 100 requests a day to the API during the initial deployment. The company decides to use API Gateway API keys to restrict access. The company creates and issues API keys for each customer.What should the company do next to meet these requirements with the LEAST administrative effort?

Create a usage plan that applies a quota of 100 requests a day. Associate the usage plan with the API keys of all customers.

Create a usage plan that applies throttling at 100 requests a day. Associate the usage plan with the API keys of all customers.

Create an Amazon DynamoDB table to track all the requests that use a particular API key. For each request to the API, count the number of records in the DynamoDB table for that day for the API key. If the number of requests is 100 or greater, generate an exception.

Create a usage plan that applies a quota of 100 requests a day. Associate the usage plan with the API keys of all customers.

Create an Amazon Aurora table to track all the requests that use a particular API key. For each request to the API, count the number of records in the Aurora table for that day for the API key. If the number of requests is 100 or greater, generate an exception.

A developer is writing a web application that allows users to sign in. The application will run on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances will run in an Auto Scaling group across multiple Availability Zones.How can the developer ensure that users stay signed in when the Auto Scaling group is scaled down?

Create an Amazon DynamoDB table. Configure the application to use the DynamoDB table to store session state such as login status.

Enable sticky sessions on the ALB target group.

Create an Amazon DynamoDB table. Configure the application to use the DynamoDB table to store session state such as login status.

Create an Amazon Elastic Block Store (Amazon EBS) volume. Use EBS Multi-Attach to attach the volume to all instances in the Auto Scaling group. Configure the application to use the volume to store session state such as login status.

Enable deregistration delay on the ALB target group.

A developer uses server-side encryption with Amazon S3 managed encryption keys (SSE-S3) to store data in Amazon S3. The developer needs to decrypt and download the encrypted objects by using the GetObject API call. What is the LEAST amount of information that the developer must provide in the API call to meet this requirement?

The S3 object key and the encryption key

The S3 object key and the Amazon Resource Name (ARN) of the AWS Key Management Service (AWS KMS) key

The S3 object key and a randomly salted Hash-based Message Authentication Code (HMAC) value of the encryption key
