A company needs to implement a solution to install specific software on Amazon EC2 instances when the instances launch.
Which solution will meet this requirement?
A. Configure AWS Systems Manager State Manager associations to bootstrap the EC2 instances with the required software at launch.A company is planning to host an application on a set of Amazon EC2 instances that are distributed across multiple Availability Zones. The application must be able to scale to millions of requests each second. A SysOps administrator must design a solution to distribute the traffic to the EC2 instances. The solution must be optimized to handle sudden and volatile traffic patterns while using a single static IP address for each Availability Zone. Which solution will meet these requirements?
A. Amazon Simple Queue Service (Amazon SQS) queueA company is deploying a third-party unit testing solution that is delivered as an Amazon EC2 Amazon Machine Image (AMI). The company is deploying the testing solution on On- Demand Instances. The company wants to use an additional three Spot Instances when the Spot Instance prices drop to a specific threshold. A minimum of three instances are required at all times to operate the testing solution. A SysOps administrator must implement high availability for the architecture.
Which solution will meet these requirements with the LEAST management overhead?
A. Configure a launch template for the Spot Instances. Set the maximum price for the Spot Instances. Configure another launch template for the On-Demand Instances.A SysOps administrator needs to ensure that an Amazon RDS for PostgreSQL DB instance has available backups The DB instance has automated backups turned on with a backup retention period of 7 days.

A. The template referenced an IAM user that is not available in eu-west-1.The company needs to increase IOPS for two EC2 instances with gp2 volumes to support an upcoming promotion with higher I/O requirements.
A. Migrate the attached EBS volumes to Throughput Optimized HDD (st1) EBS volumes.A SysOps administrator needs to automate the invocation of an AWS Lambda function. The Lambda function must run at the end of each day to generate a report on data that is stored in an Amazon S3 bucket. What is the MOST operationally efficient solution that meets these requirements?
