A DevOps engineer notices that all Amazon EC2 instances running behind an Application Load Balancer in an Auto Scaling group are failing to respond to user requests. The EC2 instances are also failing target group HTTP health checks

Upon inspection, the engineer notices the application process was not running in any EC2 instances. There are a significant number of out of memory messages in the system logs. The engineer needs to improve the resilience of the application to cope with a potential application memory leak. Monitoring and notifications should be enabled to alert when there is an issue

Which combination of actions will meet these requirements? (Select TWO.)

A.

Change the Auto Scaling configuration to replace the instances when they fail the load balancer ' s health checks.

B.

Change the target group health check HealthChecklntervalSeconds parameter to reduce the interval between health checks.

C.

Change the target group health checks from HTTP to TCP to check if the port where the application is listening is reachable.

D.

Enable the available memory consumption metric within the Amazon CloudWatch dashboard for the entire Auto Scaling group Create an alarm when the memory utilization is high Associate an Amazon SNS topic to the alarm to receive notifications when the alarm goes off

E.

Use the Amazon CloudWatch agent to collect the memory utilization of the EC2 instances in the Auto Scaling group Create an alarm when the memory utilization is high and associate an Amazon SNS topic to receive a notification.

A company has many applications. Different teams in the company developed the applications by using multiple languages and frameworks. The applications run on premises and on different servers with different operating systems. Each team has its own release protocol and process. The company wants to reduce the complexity of the release and maintenance of these applications.

The company is migrating its technology stacks, including these applications, to AWS. The company wants centralized control of source code, a consistent and automatic delivery pipeline, and as few maintenance tasks as possible on the underlying infrastructure.

What should a DevOps engineer do to meet these requirements?

A.

Create one AWS CodeCommit repository for all applications. Put each application ' s code in a different branch. Merge the branches, and use AWS CodeBuild to build the applications. Use AWS CodeDeploy to deploy the applications to one centralized application server.

B.

Create one AWS CodeCommit repository for each of the applications. Use AWS CodeBuild to build the applications one at a time. Use AWS CodeDeploy to deploy the applications to one centralized application server.

C.

Create one AWS CodeCommit repository for each of the applications. Use AWS CodeBuild to build the applications one at a time and to create one AMI for each server. Use AWS CloudFormation StackSets to automatically provision and decommission Amazon EC2 fleets by using these AMIs.

D.

Create one AWS CodeCommit repository for each of the applications. Use AWS CodeBuild to build one Docker image for each application in Amazon Elastic Container Registry (Amazon ECR). Use AWS CodeDeploy to deploy the applications to Amazon Elastic Container Service (Amazon ECS) on infrastructure that AWS Fargate manages.

A DevOps engineer is implementing governance controls for a company that requires its infrastructure to be housed within the United States. The company has many AWS accounts in an organization in AWS Organizations that has all features enabled. The engineer must restrict which AWS Regions the company can use. The engineer must also ensure that an alert is sent as soon as possible if any activity outside the governance policy occurs. The controls must be automatically enabled on any new Region outside the United States. Which combination of steps will meet these requirements? (Select TWO.)

B.

Configure AWS CloudTrail to send logs to Amazon CloudWatch Logs. Enable CloudTrail for all Regions. Use a CloudWatch Logs metric filter to create a metric in non-US Regions. Configure a CloudWatch alarm to send an alert if the metric is greater than 0.

C.

Use an AWS Lambda function that checks for AWS service activity. Deploy the Lambda function to all Regions. Write an Amazon EventBridge rule that runs the Lambda function every hour. Configure the rule to send an alert if the Lambda function finds any activity in a non-US Region.

D.

Use an AWS Lambda function to query Amazon Inspector to look for service activity in non-US Regions. Configure the Lambda function to send alerts if Amazon Inspector finds any activity.

E.

A company is optimizing its AWS costs. Most of the company’s AWS spend is for Amazon EC2. When the company analyzes its EC2 usage metrics in Amazon CloudWatch, the company observes that most of its EC2 instances are in an idle state.

The company considers an instance idle if it has a maximum CPU utilization of less than 2% in the previous 24 hours. The company evaluates metrics for instances based on 1-hour intervals. The company decides to configure a CloudWatch alarm for each EC2 instance in the account. The company wants the alarm to activate when an instance is idle.

How should the company configure the CloudWatch alarm?

A.

Select anomaly detection as the threshold type. Set the anomaly detection threshold to 2. Set Datapoints to Alarm to 24 out of 24.

B.

Select static as the threshold type. Set the threshold value to 2. Set Datapoints to Alarm to 24 out of 24.

C.

Select anomaly detection as the threshold type. Set the anomaly detection threshold to 2. Set Datapoints to Alarm to 1 out of 24.

D.

Select static as the threshold type. Set the threshold value to 2. Set Datapoints to Alarm to 1 out of 24.

A company is migrating its product development teams from an on-premises data center to a hybrid environment. The new environment will add four AWS Regions and will give the developers the ability to use the Region that is geographically closest to them.

All the development teams use a shared set of Linux applications. The on-premises data center stores the applications on a NetApp ONTAP storage device. The storage volume is mounted read-only on the development on-premises VMs. The company updates the applications on the shared volume once a week.
