NEW QUESTION 2
A customer enquires about whether all his data is secure on AWS and is especially concerned about Elastic Map Reduce (EMR) so you need to inform him of some of the security features in place for AWS. Which of the below statements would be an incorrect response to your customers enquiry?

• A. Amazon ENIR customers can choose to send data to Amazon S3 using the HTTPS protocol for secure transmission.
• B. Amazon S3 provides authentication mechanisms to ensure that stored data is secured against unauthorized access.
• C. Every packet sent in the AWS network uses Internet Protocol Security (IPsec).
• D. Customers may encrypt the input data before they upload it to Amazon S3.

Answer: C

Explanation: Amazon S3 provides authentication mechanisms to ensure that stored data is secured against unauthorized access. Unless the customer who is uploading the data specifies otherwise, only that customer can access the data. Amazon EMR customers can also choose to send data to Amazon S3
using the HTTPS protocol for secure transmission. In addition, Amazon EMR always uses HTTPS to send data between Amazon S3 and Amazon EC2. For added security, customers may encrypt the input data before they upload it to Amazon S3 (using any common data compression tool); they then need to add a decryption step to the beginning of their cluster when Amazon EMR fetches the data from Amazon S3.

You have just finshed setting up an advertisement server in which one of the obvious choices for a service was Amazon Elastic Map Reduce( EMR) and are now troubleshooting some weird cluster states that you are seeing. Which of the below is not an Amazon EMR cluster state?

• A. STARTING
• B. STOPPED
• C. RUNNING
• D. WAITING

Answer: B

Explanation: Amazon Elastic Map Reduce (EMR) is a web service that enables businesses, researchers, data analysts, and developers to easily and cost-effectively process vast amounts of data.
Amazon EMR historically referred to an Amazon EMR cluster (and all processing steps assigned to it) as a "c|uster". Every cluster has a unique identifier that starts with "j-".
The different cluster states of an Amazon EMR cluster are listed below. STARTING — The cluster provisions, starts, and configures EC2 instances. BOOTSTRAPPING — Bootstrap actions are being executed on the cluster. RUNNING — A step for the cluster is currently being run.
WAITING — The cluster is currently active, but has no steps to run. TERMINATING - The cluster is in the process of shutting down. TERMINATED - The cluster was shut down without error. TERMINATED_W|TH_ERRORS - The cluster was shut down with errors.

You are migrating a legacy client-server application to AWS. The application responds to a specific DNS domain (e.g. www.examp|e.com) and has a 2-tier architecture, with multiple application sewers and a database server. Remote clients use TCP to connect to the application sewers. The application servers need to know the IP address of the clients in order to function properly and are currently taking that information from the TCP socket.
