Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q378-Q383):

NEW QUESTION # 378
A company is hosting a web application in an AWS Region. For disaster recovery purposes, a second region is being used as a standby. Disaster recovery requirements state that session data must be replicated between regions in near-real time and 1% of requests should route to the secondary region to continuously verify system functionality. Additionally, if there is a disruption in service in the main region, traffic should be automatically routed to the secondary region, and the secondary region must be able to scale up to handle all traffic.
How should a DevOps Engineer meet these requirements?

A. In both regions, launch the application in Auto Scaling groups and use DynamoDB for session data. Use a Route 53 failover routing policy with health checks to distribute the traffic across the regions.
B. In both regions, deploy the application on AWS Elastic Beanstalk and use Amazon DynamoDB global tables for session data. Use an Amazon Route 53 weighted routing policy with health checks to distribute the traffic across the regions.
C. In both regions, launch the application in Auto Scaling groups and use DynamoDB global tables for session data. Enable an Amazon CloudFront weighted distribution across regions. Point the Amazon Route 53 DNS record at the CloudFront distribution.
D. In both regions, deploy the application in AWS Lambda, exposed by Amazon API Gateway, and use Amazon RDS PostgreSQL with cross-region replication for session data. Deploy the web application with client-side logic to call the API Gateway directly.

Answer: D

NEW QUESTION # 379
You recently encountered a major bug in your Windows-based web application during a deployment cycle.
During this failed deployment, it took the team four hours to roll back to a previously working state, which left customers with a poor user experience.
During the post-mortem, your team discussed the need to provide a quicker way to roll back failed deployments.
You currently run your web application on Amazon EC2 using Windows 2012R2 and use Elastic Load Balancing for your load balancing needs.
Which technique should you use to solve this problem?

A. Create deployable versioned bundles of your application. Store the bundles on Amazon S3.
Re-deploy your web application on Elastic Beanstalk, and enable the Elastic Beanstalk auto- rollback feature tied to CloudWatch metrics that define failure.
B. Create deployable versioned bundles of your application.
Store the bundle on Amazon S3. Re-deploy your web application using an AWS OpsWorks stack, and use AWS OpsWorks application versioning to initiate a rollback during failures.
C. Re-deploy your web application using Elastic Beanstalk, and use the Elastic Beanstalk API to trigger a FailedDeployment API call to initiate a rollback to the previous version.
D. Re-deploy your web application using an AWS OpsWorks stack, and use the AWS OpsWorks auto-rollback feature to initiate a rollback during failures.
E. Re-deploy your web application using Elastic Beanstalk, and use the Elastic Beanstalk application versions when deploying.
During failures, re-deploy the previous version to the Elastic Beanstalk environment.

Answer: E

A. Define the compliance and tagging requirements in Amazon inspector. Output the results to Amazon CloudWatch Logs. Build a metric filter to isolate the monitored elements of interest and present the data in a CloudWatch dashboard.
B. Create a resource group that displays resources with the specified tags and those without tags. Use the AWS Management Console to view compliant and non-compliant resources.
C. Use AWS Config to record configuration changes and output the data to an Amazon S3 bucket. Create an Amazon QuickSight analysis of the dataset, and use the information on dashboards and mobile devices.
D. Define the resource configurations in AWS Service Catalog, and monitor the AWS Service Catalog compliance and violations in Amazon CloudWatch. Then, set up and share a live CloudWatch dashboard. Set up Amazon SNS notifications for violations and corrections.

Answer: C

D. Createand start new instances to replace your current online instances. Then deletethe current instances.

Answer: A,D

Explanation:
Explanation
The AWS Documentation mentions the following
By default, AWS OpsWorks Stacks automatically installs the latest updates during setup, after an instance finishes booting. AWS OpsWorks Stacks does not automatically install updates after an instance is online, to avoid interruptions such as restarting application servers. Instead, you manage updates to your online instances yourself, so you can minimize any disruptions.
We recommend that you use one of the following to update your online instances.
Create and start new instances to replace your current online instances. Then delete the current instances. The new instances will have the latest set of security patches installed during setup.
On Linux-based instances in Chef 11.10 or older stacks, run the Update Dependencies stack command, which installs the current set of security patches and other updates on the specified instances.
