Your application is currently running on Amazon EC2 instances behind a load balancer. Your management has decided
to use a Blue/Green deployment strategy. How should you implement this for each deployment?
You have an application consisting of a stateless web server tier running on Amazon EC2 instances behind load balancer,
and are using Amazon RDS with read replicas. Which of the following methods should you use to implement a selfhealing and cost-effective architecture? (Choose two.)
You have a code repository that uses Amazon S3 as a data store. During a recent audit of your security controls, some
concerns were raised about maintaining the integrity of the data in the Amazon S3 bucket. Another concern was raised
around securely deploying code from Amazon S3 to applications running on Amazon EC2 in a virtual private cloud. What
are some measures that you can implement to mitigate these concerns? (Choose two.)
Your company releases new features with high frequency while demanding high application availability. As part of the
application’s A/B testing, logs from each updated Amazon EC2 instance of the application need to be analyzed in near
real-time, to ensure that the application is working flawlessly after each deployment. If the logs show arty anomalous
behavior, then the application version of the instance is changed to a more stable one. Which of the following methods
should you use for shipping and analyzing the logs in a highly available manner?

You currently run your infrastructure on Amazon EC2 instances behind an Auto Scaling group> All logs for you application
are currently written to ephemeral storage. Recently your company experienced a major bug in code that made it through
testing and was ultimately deployed to your fleet. This bug triggered your Auto Scaling group to scale up and back down
before you could successfully retrieve the logs off your server to better assist you in troubleshooting the bug. Which
technique should you use to make sure you are able to review your logs after your instances have shut down?
The project you are working on currently uses a single AWS CloudFormation template to deploy its AWS infrastructure,
which supports a multi-tier web application. You have been tasked with organizing the AWS CloudFormation resources
so that they can be maintained in the future, and so that different departments such as Networking and Security can
review the architecture before it goes to Production. How should you do this in a way that accommodates each department,
using their existing workflows?
