You have deployed an application to AWS which makes use of Autoscaling to launch new instances. You now want to change the instance type for the new instances. Which of the following is one of the action items to achieve this deployment?
Explanation:
The ideal way is to create a new launch configuration, attach it to the existing Auto Scaling group, and terminate the running instances. Option A is invalid because Clastic beanstalk cannot launch new instances on demand. Since the current scenario requires Autoscaling, this is not the ideal option Option B is invalid because this will be a maintenance overhead, since you just have an Autoscaling Group. There is no need to create a whole Cloudformation template for this. Option D is invalid because Autoscaling Group will still launch CC2 instances with the older launch configuration.

You run a 2000-engineer organization. You are about to begin using AWS at a large scale for the first time. You want to integrate with your existing identity management system running on Microsoft Active Directory, because your organization is a power-user of Active Directory. How should you manage your AWS identities in the most simple manner?
Explanation:
You must use AD Connector as a power-user of Microsoft Active Directory. Simple AD only works with a subset of AD functionality. Sync Domains do not exist; they are made up answers. AD Connector is a directory gateway that allows you to proxy directory requests to your on-premises Microsoft Active Directory, without caching any information in the cloud. AD Connector comes in 2 sizes; small and large. A small AD Connector is designed for smaller organizations of up to 500 users. A large AD Connector is designed for larger organizations of up to 5,000 users.

A DevOps Engineer must improve the monitoring of a Finance team payments microservice that handles transactions for an e-commerce platform. The microservice runs on multiple Amazon EC2 instances.

A Development team is building more than 40 applications. Each app is a three-tiered web application based on an ELB Application Load Balancer, Amazon EC2, and Amazon RDS. Because the applications will be used internally, the Security team wants to allow access to the 40 applications only from the corporate network and block access from external IP addresses. The corporate network reaches the internet through proxy servers. The proxy servers have 12 proxy IP addresses that are being changed one or two times per month. The Network Infrastructure team manages the proxy servers; they upload the file that contains the latest proxy IP addresses into an Amazon S3 bucket. The DevOps Engineer must build a solution to ensure that the applications are accessible from the corporate network. Which solution achieves these requirements with MINIMAL impact to application development, MINIMAL operational effort, and the LOWEST infrastructure cost?

A consulting company was hired to assess security vulnerabilities within a client company’s application and propose a plan to remediate all identified issues. The architecture is identified as follows: Amazon S3 storage for content, an Auto Scaling group of Amazon EC2 instances behind an Elastic Load Balancer with attached Amazon EBS storage, and an Amazon RDS MySQL database. There are also several AWS Lambda functions that communicate directly with the RDS database using connection string statements in the code.
The consultants identified the top security threat as follows: the application is not meeting its requirement to have encryption at rest. What solution will address this issue with the LEAST operational overhead and will provide monitoring for potential future violations?
