NEW QUESTION # 517
A retail company has adopted AWS OpsWorks for managing its deployments. In the last three months, the company has discovered that some production instances have been restarting without reason. Upon inspection of the AWS CloudTrail logs, a DevOps Engineer determined that those instances were restarted by OpsWorks.
The Engineer now wants automated email notifications whenever OpsWorks restarts an instance when the instance is deemed unhealthy or unable to communicate with the service endpoint.
How can the Engineer meet this requirement?

  • A. Create a subscription for this topic that contains the email address. Enable instance restart notifications within the OpsWorks layer and indicate the destination email address for the notification
  • B. Create an Amazon SNS topic and create a subscription for this topic that contains the destination email address. Create an Amazon CloudWatch rule specify as a source and specify instance-replacement in the initiated_by details. Use the SNS topic as a target. aws.opsworks
  • C. Create a Chef recipe to place a cron to run a custom script within the Amazon EC2 instances that sends an email to the team by using Amazon SES if the OpsWorks agent detects an instance failure.
  • D. Create an Amazon SNS topic and create a subscription for this topic that contains the destination email address. Create an Amazon CloudWatch rule: specify as a source and specify auto-healing in the initiated_by details. Use the SNS topic as a target. aws.opsworks

Answer: B


NEW QUESTION # 518
A company is migrating its public-facing software to AWS. The company plans to use Amazon EC2 to run application code and Amazon RDS to store all application data. The company wants to primarily use one Region with failover capabilities to a secondary Region and Amazon Route
53 to route traffic. The RPO is 2 hours and the RTO is 4 hours.
Which combination of steps should be used to meet these requirements while MINIMIZING cost?
(Choose three.)

  • A. In the event of a failure, deploy a new AWS CloudFormation stack in a secondary region to provision the application resources and a replica of the RDS database using the copied snapshot and a Route 53 latency-based routing policy.
  • B. Configure Amazon CloudWatch Events rules to run every 3 hours.
    Trigger AWS Lambda functions to create an RDS snapshot and copy it to the secondary Region.
  • C. Create an AWS CloudFormation template to provision the application server and database instance in a single Region.
  • D. In the event of a failure, deploy a new AWS CloudFormation stack in a secondary region to provision the application resources and a new RDS instance using the copied snapshot and a Route 53 failover routing policy.
  • E. Configure Amazon CloudWatch Events rules to run every hour.
    Trigger AWS Lambda functions to create an RDS snapshot and copy it to the secondary Region.
  • F. Create an AWS CloudFormation template to provision the application tier of the application and a multi- Region database instance.

Answer: C,D,E

Explanation:
B) is Wrong multi-Region database instance does not minimize the costs
D) is not correct due to RPO of 2 hours
F) replica of the RDS database and a Route 53 latency-based routing are not the use case


NEW QUESTION # 519
Which of the following features of the Autoscaling Group ensures that additional instances are neither launched or terminated before the previous scaling activity takes effect

  • A. Creation policy
  • B. Cool down period
  • C. Ramp up period
  • D. Termination policy

Answer: B

Explanation:
Explanation
The AWS documentation mentions
The Auto Scaling cooldown period is a configurable setting for your Auto Scaling group that helps to ensure that Auto Scaling doesn't launch or terminate additional instances before the previous scaling activity takes effect. After the Auto Scaling group dynamically scales using a simple scaling policy. Auto Scaling waits for the cooldown period to complete before resuming scaling activities. When you manually scale your Auto Scaling group, the default is not to wait for the cooldown period, but you can override the default and honor the cooldown period. If an instance becomes unhealthy. Auto Scaling does not wait for the cooldown period to complete before replacing the unhealthy instance For more information on the Cool down period, please refer to the below URL:

NEW QUESTION # 520
Your application is currently running on Amazon EC2 instances behind a load balancer. Your management has decided to use a Blue/Green deployment strategy. How should you implement this for each deployment?

  • A. Using AWS CloudFormation, create a test stack for validating the code, and then deploy the code to each production Amazon EC2 instance.
  • B. Launch more Amazon EC2 instances to ensure high availability, de-register each Amazon EC2 instance from the load balancer, upgrade it, and test it, and then register it again with the load balancer.
  • C. Create a new load balancer with new Amazon EC2 instances, carry out the deployment, and then switch DNS over to the new load balancer using Amazon Route 53 after testing.
  • D. Set up Amazon Route 53 health checks to fail over from any Amazon EC2 instance that is currently being deployed to.

Answer: C

Explanation:
Explanation
The below diagram shows how this can be done

1) First create a new ELB which will be used to point to the new production changes.
2) Use the Weighted Route policy for Route53 to distribute the traffic to the 2 ELB's based on a 80-20% traffic scenario. This is the normal case, the % can be changed based on the requirement.
3) Finally when all changes have been tested, Route53 can be set to 100% for the new ELB.
Option A is incorrect because this is a failover scenario and cannot be used for Blue green deployments. In Blue Green deployments, you need to have 2 environments running side by side.
Option B is incorrect, because you need to a have a production stack with the changes which will run side by side.
Option D is incorrect because this is not a blue green deployment scenario. You cannot control which users will go the new EC2 instances.
For more information on blue green deployments, please refer to the below document link: from AWS

NEW QUESTION # 521
A company is adopting AWS CodeDeploy to automate its application deployments for a Java-Apache Tomcat application with an Apache webserver. The Development team started with a proof of concept, created a deployment group for a developer environment, and performed functional tests within the application. After completion, the team will create additional deployment groups for staging and production The current log level is configured within the Apache settings, but the team wants to change this configuration dynamically when the deployment occurs, so that they can set different log level configurations depending on the deployment group without having a different application revision for each group.
How can these requirements be met with the LEAST management overhead and without requiring different script versions for each deployment group?

  • A. Create a script that uses the CodeDeploy environment variable DEPLOYMENT_GROUP_NAME to identify which deployment group the instances is part of. Use this information to configure the log level settings. Reference this script as part of the Beforelnstall lifecycle hook in the appspec.yml file
  • B. Create a script that uses the CodeDeploy environment variable DEPLOYMENT_GROUP_ID to identify which deployment group the instance is part of to configure the log level settings. Reference this script as part of the Install lifecycle hook in the appspec yml file.
  • C. Create a CodeDeploy custom environment variable for each environment. Then place a script into the application revision that checks this environment variable to identify which deployment group the instance is part of. Use this information to configure the log level settings. Reference this script as part of the ValidateService lifecycle hook in the appspec yml file.
  • D. Tag the Amazon EC2 instances depending on the deployment group. Then place a script into the application revision that calls the metadata service and the EC2 API to identify which deployment group the instance is part of. Use this information to configure the log level settings. Reference the script as part of the Afterinstall lifecycle hook in the appspec yml file.

Answer: C
