Que.01: As part of your continuous deployment process your application undergoes an I/O load performance test before it is deployed to production using new AMIs. The application uses one Amazon EBS PIOPS volume per instance and requires consistent I/O performance. Which of the following must be carried out to ensure that I/O load performance tests yield the correct results in a repeatable manner Options: a Ensure that the I/O block sizes for the test are randomly selected. b Ensure that the Amazon EBS volumes have been pre-warmed by reading all the blocks before the test. c Ensure that snapshots of the Amazon EBS volumes are created as a backup. d Ensure that the Amazon EBS volume is encrypted. e Ensure that the Amazon EBS volume has been pre-warmed by creating a snapshot of the volume before the test.

Que.02: Your team is responsible for an AWS Elastic Beanstalk application. The business requires that you move to a continuous deployment model releasing updates to the application multiple times per day with zero downtime. What should you do to enable this and still be able to roll back almost immediately in an emergency to the previous version Options: a Enable rolling updates in the Elastic Beanstalk environment setting an appropriate pause time for application startup. b Develop the application to poll for a new application version in your code repository download and install to each running Elastic Beanstalk instance. c Create a second Elastic Beanstalk environment running the new application version and swap the environment CNAMEs. d Create a second Elastic Beanstalk environment with the new application version and configure the old environment to redirect clients using the HTTP 301 response code to the new environment.

Que.03: Your application has a single Amazon EC2 instance that processes orders with a third-party supplier. Orders are retrieved from an Amazon SQS queue and processed in batches every five minutes. There is a business requirement that delays in processing should be no more than one hour. Approximately three times a week the application fails and orders stop being processed requiring a manual restart. Which steps should you take to make this more resilient in a cost-effective way Choose 2 Options: a Create a second ‘ w a tc h d o g ’ instance configured to monitor the processing instance and restart it if a failure is detected. b Create an Auto Scaling launch configuration to launch instances configured to perform processing. Create an Auto Scaling group to use the launch configuration with a minimum and maximum of one. c Create an Auto Scaling launch configuration to launch instances configured to perform processing. Create an Auto Scaling group to use the launch configuration with a minimum of two and a maximum of ten and to scale based on the size of the Amazon SQS queue. d Create a load balancer and register your instance with Elastic Load Balancing. Set the Elastic Load Balancing health check to call an HTTP endpoint in your application that executes the processing. e Modify the processing application to send a custom CloudWatch metric with a dimension of InstanceId. Create a CloudWatch alarm configured when the metric is in an Insufficient state for 10 minutes to take an Amazon EC2 action to terminate the instance. Become successful with VMExam.com

Que.04: After reviewing the last quarter’s monthly bills management has noticed an increase in the overall bill from Amazon. After researching this increase in cost you discovered that one of your new services is doing a lot of GET Bucket API calls to Amazon S3 to build a metadata cache of all objects in the applications bucket. Your boss has asked you to come up with a new cost-effective way to help reduce the amount of these new GET Bucket API calls. What process should you use to help mitigate the cost Options: a Update your Amazon S3 b u c k e t s ’ lifecycle policies to automatically push a list of objects to a new bucket and use this list to view objects associated with the a p p l i c a t i o n ’ s bucket. b Create a new DynamoDB table. Use the new DynamoDB table to store all metadata about all objects uploaded to Amazon S3. Any time a new object is uploaded update the a p p l i c a t i o n ’ s internal Amazon S3 object metadata cache from DynamoDB. c Using Amazon SNS create a notification on any new Amazon S3 objects that automatically updates a new DynamoDB table to store all metadata about the new object. Subscribe the application to the Amazon SNS topic to update its internal Amazon S3 object metadata cache from the DynamoDB table. d Upload all images to Amazon SQS set up SQS lifecycles to move all images to Amazon S3 and initiate an Amazon SNS notification to your application to update the a p p l i c a t i o n ’ s internal Amazon S3 object metadata cache. e Upload all images to an ElastiCache filecache server. Update your application to now read all file metadata from the ElastiCache filecache server and configure the ElastiCache policies to push all files to Amazon S3 for long-term storage.

Que.05: Your current log analysis application takes more than four hours to generate a report of the top 10 users of your web application. You have been asked to implement a system that can report this information in real time ensure that the report is always up to date and handle increases in the number of requests to your web application. Choose the option that is cost-effective and can fulfill the requirements. Options: a Publish your data to CloudWatch Logs and configure your application to autoscale to handle the load on demand. b Publish your log data to an Amazon S3 bucket. Use AWS CloudFormation to create an Auto Scaling group to scale your post-processing application which is configured to pull down your log files stored in Amazon S3. c Configure an Auto Scaling group to increase the size of your Amazon EMR cluster. d Post your log data to an Amazon Kinesis data stream and subscribe your log-processing application so that is configured to process your logging data. e Create a multi-AZ Amazon RDS MySQL cluster post the logging data to MySQL and run a map reduce job to retrieve the required information on user counts.
