A developer has designed a customer, facing application that is running on an Amazon EC2 instance. The application logs every request made to it. The application usually runs seamlessly, but a spike in traffic generates several logs that cause the disk to fill up and eventually run out of memory Company policy requires old to be centralized for analysis.
Which long-term solution should the developer employ to prevent the issue from reoccurring?

• A.Enable AWS Auto Scaling on Amazon Elastic Block Store (Amazon EBS) to automatically add volumes to the instance when it reaches a specified threshold.
• B.Create an Amazon EventBridge (Amazon CloudWatch Events) rule to pull the logs from the instance. Configure the rule to delete the logs they have been pulled.
• C.Enable AWS Auto Scaling on Amazon Elastic Block Store (Amazon EBS) a outomatically add volume to the instance when it reaches a specified threshold.
• D.Install the Amazon CloudWatch agent on the instance to send the logs to CloudWatch. Delete the logs from the instance once they are sent to CloudWatch.

• B.Enable a DynamoDB stream that publishes an Amazon SNS message. Trigger the Lambda function synchronously from the SNS message.
• C.Enable a DynamoDB stream that publishes an SNS message. Trigger the Lambda function asynchronously from the SNS message.

A developer is creating a new application that will be accessed by users through an API created using Amazon API Gateway The users need to be authenticated by a third-party Security Assertion Markup Language (SAML) identity provider Once authenticated, users will need access to other AWS services such as Amazon S3 and Amazon DynamoDB
How can these requirements be met?

• A.Use Amazon Cognito Identity pools with a SAML identity provider as one of the authentication providers
• B.Use Amazon CloudFront signed URLs to connect with the SAML identity provider
• C.Use an Amazon Cognito user pool with SAML as the resource server
• D.Use the AWS IAM service to provide the sign-up and sign-in functionality.

A company is building an application to track athlete performance using an Amazon DynamoDB table. Each item in the table is identified by a partition key (user_id) and a sort key (sport_name). The table design is shown below:

(Note: Not all table attributes are shown)
A Developer is asked to write a leaderboard application to display the top performers (user_id) based on the score for each sport_name.
What process will allow the Developer to extract results MOST efficiently from the DynamoDB table?

• A.Use a DynamoDB query operation with the key attributes of user_id and sport_name and order the results based on the score attribute.
• B.Create a global secondary index with a partition key of sport_name and a sort key of score, and get the results
• C.Use a DynamoDB scan operation to retrieve scores and user_id based on sport_name, and order the results based on the score attribute.
• D.Create a local secondary index with a primary key of sport_name and a sort key of score and get the results based on the score attribute.
