You have been asked to use your department’s existing continuous integration (CI) tool to test a three- tier web architecture defined in an AWS CloudFormation template. The tool already supports AWS APIs and can launch new AWS CloudFormation stacks after polling version control. The CI tool reports on the success of the AWS CloudFormation stack creation by using the DescribeStacks API to look for the CREATE_COMPLETE status.
The architecture tiers defined in the template consist of:
. One load balancer
. Five Amazon EC2 instances running the web application
. One multi-AZ Amazon RDS instance How would you implement this? Choose 2 answers

Your social media marketing application has a component written in Ruby running on AWS Elastic BeanStalk. This application component posts messages to social media sites in support of various marketing campaigns. Your management now requires you to record replies to these social media messages to analyze the effectiveness of the marketing campaign in comparison to past and future efforts. You have already developed a new application component to interface with the social media site APIs in order to read the replies.
Which process should you use to record the social media replies in a durable data store that can be accessed at any time for analysis of historical data?
A telecommunications company needs to predict customer churn (i.e. customers eho decide to switch a computer). The company has historic records of each customer, including monthly consumption patterns, calls to customer service, and whether the customer ultimately quit th eservice. All of this data is stored in Amazon S3. The company needs to know which customers are likely going to churn soon so that they can win back their loyalty.
What is the optimal approach to meet these requirements?
An organization has configured a VPC with an Internet Gateway (IGW). Pairs of public and private subnets (each with one subnet per Availability Zone), and an Elastic Load Balancer (ELB) configured to use the public subnets. The application’s web tier leverages the ELB. Auto Scaling and a multi-AZ RDS database instance the organization would like to eliminate any potential single points of failure in this design.
What step should you take to achieve this organization's objective?

Managers in a company need access to the human resources database that runs on Amazon Redshift, to run reports about their employees. Managers must only see information about their direct reports.
Which technique should be used to address this requirement with Amazon Redshift?
An organization is using Amazon Kinesis Data Streams to collect data generated from thousands of temperature devices and is using AWS Lambda to process the data. Devices generate 10 to 12 million records every day, but Lambda is processing only around 450 thousand records. Amazon CloudWatch indicates that throttling on Lambda is not occurring.
What should be done to ensure that all data is processed? (Choose two.)
Which of the following instance types are available as Amazon EBS backend only?
An organization is setting up a data catalog and metadata management environment for their numerous data stores currently running on AWS. The data catalog will be used to determine the structure and other attributes of data in the data stores. The data stores are composed of Amazon RDS databases, Amazon Redshift, and CSV files residing on Amazon S3. The catalog should be populated on a scheduled basis, and minimal administration is required to manage the catalog.
How can this be accomplished?
Which data store should the organization choose?
A data engineer is running a DWH on a 25-node Redshift cluster of a SaaS service. The data engineer needs to build a dashboard that will be used by customers. Five big customers represent 80% of usage, and there is a long tail of dozens of smaller customers. The data engineer has selected the dashboarding tool.
How should the data engineer make sure that the larger customer workloads do NOT interfere with the smaller customer workloads?

You have a video Trans coding application running on Amazon EC2. Each instance pools a queue to find out which video should be Trans coded, and then runs a Trans coding process.
If this process is interrupted, the video will be Trans coded by another instance based on the queuing system. You have a large backlog of videos which need to be Trans coded and would like to reduce this backlog by adding more instances. You will need these instances only until the backlog is reduced. Which type of Amazon EC2 instance should you use to reduce the backlog in the most cost-effective way?
By default what are ENIs that are automatically created and attached to instances using the EC2 console set to do when the attached instance terminates?

The application runs on an Amazon EC2 instance
Access to the DynamoDB table must be secure within the VPC
Minimal changes to application code to improve performance using write-through cache
