A company is implementing an application on Amazon EC2 instances. The application needs to
process incoming transactions. When the application detects a transaction that is not valid, the
application must send a chat message to the company's support team. To send the message, the
application needs to retrieve the access token to authenticate by using the chat API.
A developer needs to implement a solution to store the access token. The access token must be
encrypted at rest and in transit. The access token must also be accessible from other AWS accounts.
Which solution will meet these requirements with the LEAST management overhead?
Question No 2
A company is running Amazon EC2 instances in multiple AWS accounts. A developer needs to
implement an application that collects all the lifecycle events of the EC2 instances. The application
needs to store the lifecycle events in a single Amazon Simple Queue Service (Amazon SQS) queue in
the company's main AWS account for further processing.
Which solution will meet these requirements?
Question No 3
An application is using Amazon Cognito user pools and identity pools for secure access. A developer
wants to integrate the user - specific file upload and download features in the application with
Amazon S3. The developer must ensure that the files are saved and retrieved in a secure manner and
that users can access only their own files. The file sizes range from 3 KB to 300 MB.
Which option will meet these requirements with the HIGHEST level of security?
Question No 4
A company is building a scalable data management solution by using AWS services to improve the
speed and agility of development. The solution will ingest large volumes of data from various sources
and will process this data through multiple business rules and transformations.
The solution requires business rules to run in sequence and to handle reprocessing of data if errors
occur when the business rules run. The company needs the solution to be scalable and to require the
least possible maintenance.
Which AWS service should the company use to manage and automate the orchestration of the data
flows to meet these requirements?
Question No 5
A developer has created an AWS Lambda function that is written in Python. The Lambda function
reads data from objects in Amazon S3 and writes data to an Amazon DynamoDB table. The function is
successfully invoked from an S3 event notification when an object is created. However, the function
fails when it attempts to write to the DynamoDB table.
What is the MOST likely cause of this issue?
