A developer has created an AWS Lambda function to provide notification through Amazon Simple Notification Service (Amazon SNS) whenever a file is uploaded to Amazon S3 that is larger than 50 MB. The developer has deployed and tested the Lambda function by using the CLI. However, when the event notification is added to the S3 bucket and a 3.000 MB file is uploaded, the Lambda function does not launch.
Which of the following Is a possible reason for the Lambda function's inability to launch?

• A.Lambda functions cannot be invoked directly from an S3 event.
• B.The resource-based policy for the Lambda function does not have the required permissions to be invoked by Amazon S3.

A company has an existing application that has hardcoded database credentials A developer needs to modify the existing application The application is deployed in two AWS Regions with an active-passive failover configuration to meet company's disaster recovery strategy The developer needs a solution to store the credentials outside the code. The solution must comply With the company's disaster recovery strategy Which solution Will meet these requirements in the MOST secure way?

• A.Store the credentials in AWS Secrets Manager in the primary Region. Enable secret replication to the secondary Region Update the application to use the Amazon Resource Name (ARN) based on the Region.
• B.Store credentials in AWS Systems Manager Parameter Store in the primary Region. Enable parameter replication to the secondary Region. Update the application to use the Amazon Resource Name (ARN) based on the Region.
• C.Store credentials in a config file. Upload the config file to an S3 bucket in me primary Region. Enable Cross-Region Replication (CRR) to an S3 bucket in the secondary region. Update the application to access the config file from the S3 bucket based on the Region.
• D.Store credentials in a config file. Upload the config file to an Amazon Elastic File System (Amazon EFS) file system. Update the application to use the Amazon EFS file system Regional endpoints to access the config file in the primary and secondary Regions.

In case of any application errors, the developer wants to be able to use Amazon CloudWatch to monitor and troubleshoot all applications from one place.
How can the developer accomplish this?

• A.Install an AWS SDK on the on-premises server to automatically send logs to CloudWatch.
• B.Download the CloudWatch agent to the on-premises server. Configure the agent to use IAM user credentials with permissions for CloudWatch.
• C.Upload log files from the on-premises server to Amazon S3 and have CloudWatch read the files.
• D.Upload log files from the on-premises server to an Amazon EC2 instance and have the instance forward the logs to CloudWatch.

A company has an ecommerce application. To track product reviews, the company's development team uses an Amazon DynamoDB table.
Every record includes the following
* A Review ID a 16-digrt universally unique identifier (UUID)
* A Product ID and User ID 16 digit UUlDs that reference other tables
* A Product Rating on a scale of 1-5
* An optional comment from the user
The table partition key is the Review ID. The most performed query against the table is to find the 10 reviews with the highest rating for a given product.
Which index will provide the FASTEST response for this query"?

• A.A global secondary index (GSl) with Product ID as the partition key and Product Rating as the sort key
• B.A global secondary index (GSl) with Product ID as the partition key and Review ID as the sort key
• C.A local secondary index (LSI) with Product ID as the partition key and Product Rating as the sort key
• D.A local secondary index (LSI) with Review ID as the partition key and Product ID as the sort key
