A company receives clickstream data files to Amazon S3 every five minutes. A Python script runs as a cron job once a day on an Amazon EC2 instance to process each file and load it into a database hosted on Amazon RDS. The cron job takes 15 to 30 minutes to process 24 hours of data. The data consumers ask for the data be available as soon as possible.
Which solution would accomplish the desired outcome?

• A.Convert the cron job to an AWS Lambda function and schedule it to run once an hour using Amazon CloudWatch events.
• B.Create an AWS Lambda function that runs when a file is delivered to Amazon S3 using S3 event notifications.
• C.Increase the size of the instance to speed up processing and update the schedule to run once an hour.
• D.Convert the cron job to an AWS Lambda function and trigger this new function using a cron job on an EC2 instance.

A large company experienced a drastic increase in its monthly AWS spend. This is after Developers accidentally launched Amazon EC2 instances in unexpected regions. The company has established practices around least privileges for Developers and controls access to on-premises resources using Active Directory groups. The company now wants to control costs by restricting the level of access that Developers have to the AWS Management Console without impacting their productivity. The company would also like to allow Developers to launch Amazon EC2 in only one region, without limiting access to other services in any region.
How can this company achieve these new security requirements while minimizing the administrative burden on the Operations team?

• A.Set up SAML-based authentication tied to an IAM role that has an AdministrativeAccess managed policy attached to it. Attach a customer managed policy that denies access to Amazon EC2 in each region except for the one required.
• B.Create an IAM user for each Developer and add them to the developer IAM group that has the PowerUserAccess managed policy attached to it. Attach a customer managed policy that allows the Developers access to Amazon EC2 only in the required region.
• C.Set up SAML-based authentication tied to an IAM role that has a PowerUserAccess managed policy and a customer managed policy that deny all the Developers access to any AWS services except AWS Service Catalog. Within AWS Service Catalog, create a product containing only the EC2 resources in the approved region.
• D.Set up SAML-based authentication tied to an IAM role that has the PowerUserAccess managed policy attached to it. Attach a customer managed policy that denies access to Amazon EC2 in each region except for the one required.

An enterprise runs 103 line-of-business applications on virtual machines in an on-premises data center. Many of the applications are simple PHP. Java, or Ruby web applications, are no longer actively developed, and serve little traffic.
Which approach should be used to migrate these applications to AWS with the LOWEST infrastructure costs?

• A.Convert each application to a Docker image and deploy to a small Amazon ECS cluster behind an Application Load Balancer.
• B.Deploy the applications lo single-instance AWS Elastic Beanstalk environments without a load balancer.
• C.Use VM Import/Export to create AMls for each virtual machine and run them in single-instance AWS Elastic Beanstalk environments by configuring a custom image.
• D.Use AWS SMS to create AMls for each virtual machine and run them in Amazon EC2.
