Which of the following entities should be used for an Amazon Elastic Compute Cloud (Amazon EC2) Instance to access a DynamoDB table?Question 30Answera.AWS Key Management Service (KMS)b.IAM rolec.Amazon Cognitod.AWS IAM user access keys
Solution
The correct entity to use for an Amazon Elastic Compute Cloud (Amazon EC2) Instance to access a DynamoDB table is b. IAM role.
Here's why:
a. AWS Key Management Service (KMS) - This is used for creating and managing cryptographic keys and controlling their use across a wide range of AWS services and in your applications. It's not specifically used for granting access to DynamoDB tables.
b. IAM role - This is the correct answer. An IAM role is an AWS identity with permission policies that determine what the identity can and can't do in AWS. You can attach an IAM role with the necessary permissions to an EC2 instance, which then allows applications running on the instance to use AWS services.
c. Amazon Cognito - This is a service that helps you create unique identities for your users and authenticate them for secure access to your apps, rather than for accessing DynamoDB tables from EC2 instances.
