Which of these is not an instrinsic function in AWS CloudFormation?
After a daily scrum with your development teams, you've agreed that using Blue/Green style deployments would benefit the team. Which technique should you use to deliver this new requirement?
An application has microservices spread across different AWS accounts and is integrated with an on-premises legacy system for some of its functionality. Because of the segmented architecture and missing logs, every time the application experiences issues, it is taking too long to gather the logs to identify the issues. A DevOps Engineer must fix the log aggregation process and provide a way to centrally analyze the logs. Which is the MOST efficient and cost-effective solution?
A DevOps Engineer must create a Linux AMI in an automated fashion. The newly created AMI identification must be stored in a location where other build pipelines can access the new identification programmatically What is the MOST cost-effective way to do this?
For AWS Auto Scaling, what is the first transition state an existing instance enters after leaving steady state in Standby mode?
A company hosts parts of a Python-based application using AWS Elastic Beanstalk. An Elastic Beanstalk CLI is being used to create and update the environments. The Operations team detected an increase in requests in one of the Elastic Beanstalk environments that caused downtime overnight. The team noted that the policy used for AWS Auto Scaling is NetworkOut. Based on load testing metrics, the team determined that the application needs to scale CPU utilization to improve the resilience of the environments. The team wants to implement this across all environments automatically. Following AWS recommendations, how should this automation be implemented?
If you want CloudFormation stack status updates to show up in a continuous delivery system in as close to real time as possible, how should you achieve this?
A company updated the AWS CloudFormation template for a critical business application. The stack update process failed due to an error in the updated template, and AWS CloudFormation automatically began the stack rollback process. Later, a DevOps engineer discovered that the application was still unavailable and that the stack was in the UPDATE_ROLLBACK_FAILED state. Which combination of actions should the DevOps engineer perform so that the stack rollback can complete successfully? (Choose two.)
A user has attached an EBS volume to a running Linux instance as a "/dev/sdf" device. The user is unable to see the attached device when he runs the command "df -h". What is the possible reason for this?
An application running on a set of Amazon EC2 instances in an Auto Scaling group requires a configuration file to operate. The instances are created and maintained with AWS CloudFormation. A DevOps engineer wants the instances to have the latest configuration file when launched, and wants changes to the configuration file to be reflected on all the instances with a minimal delay when the CloudFormation template is updated. Company policy requires that application configuration files be maintained along with AWS infrastructure configuration files in source control. Which solution will accomplish this?

A DevOps Engineer must automate a weekly process of identifying unnecessary permissions on a per-user basis, across all users in an AWS account. This process should evaluate the permissions currently granted to each user by examining the user’s attached IAM access policies compared to the permissions the user has actually used in the past 90 days. Any differences in the comparison would indicate that the user has more permissions than are required. A report of the deltas should be sent to the Information Security team for further review and IAM user access policy revisions, as required. Which solution is fully automated and will produce the MOST detailed deltas report?

A.
Create an AWS Lambda function that calls the IAM Access Advisor API to pull service permissions granted on a user-byuser basis for all users in the AWS account. Ensure that Access Advisor is configured with a tracking period of 90 days.Invoke the Lambda function using an Amazon CloudWatch Events rule on a weekly schedule. For each record, by user, by service, if the Access Advisor Last Accesses field indicates a day count instead of “Not accesses in the tracking period,” this indicates a delta compared to what is in the user’s currently attached access polices. After Lambda has iterated through all users in the AWS account, configure it to generate a report and send the report using Amazon SES.

B.
Configure an AWS CloudTrail trail that spans all AWS Regions and all read/write events, and point this trail to an Amazon S3 bucket. Create Amazon Athena table and specify the S3 bucket ARN in the CREATE TABLE query. Create an AWS Lambda function that accesses the Athena table using the SDK, which performs a SELECT, ensuring that the WHERE clause includes userIdentity, eventName, and eventTime. Compare the results against the user’s currently attached IAM access policies to determine any deltas. Configure an Amazon CloudWatch Events schedule to automate this process to run once a week. Configure Amazon SES to send a consolidated report to the Information Security team.

C.
Configure VPC Flow Logs on all subnets across all VPCs in all regions to capture user traffic across the entire account. Ensure that all logs are being sent to a centralized Amazon S3 bucket, so all flow logs can be consolidated and aggregated. Create an AWS Lambda function that is triggered once a week by an Amazon CloudWatch Events schedule. Ensure that the Lambda function parses the flow log files for the following information: IAM user ID, subnet ID, VPC ID, Allow/ Reject status per API call, and service name. Then have the function determine the deltas on a user-by-user basis. Configure the Lambda function to send the consolidated report using Amazon SES.

Create an Amazon ES cluster and note its endpoint URL, which will be provided as an environment variable into a Lambda function. Configure an Amazon S3 event on a AWS CloudTrail trail destination S3 bucket and ensure that the event is configured to send to a Lambda function. Create the Lambda function to consume the events, parse the input from JSON, and transform it to an Amazon ES document format. POST the documents to the Amazon ES cluster’s endpoint by way of the passed-in environment variable. Make sure that the proper indexing exists in Amazon ES and use Apache Lucene queries to parse the permissions on a user-by-user basis. Export the deltas into a report and have Amazon ES send the reports to the Information Security team using Amazon SES every week.
