Amazon AWS Certified CloudOps Engineer - Associate Sample Questions (Q39-Q44):

NEW QUESTION # 39
A company runs several production workloads on Amazon EC2 instances. A SysOps administrator discovered that a production EC2 instance failed a system health check. The SysOps administrator recovered the instance manually.
The SysOps administrator wants to automate the recovery task of EC2 instances and receive notifications whenever a system health check fails. Detailed monitoring is activated for all of the company's production EC2 instances.
Which of the following is the MOST operationally efficient solution that meets these requirements?

A. On each production EC2 instance, configure an Amazon CloudWatch agent to collect and send logs to a log group in Amazon CloudWatch Logs. Create a CloudWatch alarm that is based on a metric filter that tracks errors. Configure the alarm to invoke an AWS Lambda function to reboot the EC2 instance and send a notification email.
B. On each production EC2 instance, create a script that sends network pings to a highly available endpoint by way of a cron job. If the script detects a network response timeout, invoke a command to reboot the EC2 instance.
C. For each production EC2 instance, create an Amazon CloudWatch alarm for Status Check Failed:
System. Set the alarm action to recover the EC2 instance. Configure the alarm notification to be published to an Amazon Simple Notification Service (Amazon SNS) topic.
D. On each production EC2 instance, create a script that monitors the system health by sending a heartbeat notification every minute to a central monitoring server. If an EC2 instance fails to send a heartbeat, run a script on the monitoring server to stop and start the EC2 instance and to publish a notification to an Amazon Simple Notification Service (Amazon SNS) topic.

Answer: C

Explanation:
EC2 status checks run every minute and expose a System check metric that indicates hardware or system-level impairment. CloudWatch alarms can trigger on Status Check Failed: System and automatically recover the instance (or take a defined action) without manual intervention, satisfying both the automatic recovery and alerting requirements. This approach minimizes manual steps and scales across many instances, leveraging built-in AWS health signals and standard notification channels. It is also consistent with AWS guidance on using CloudWatch alarms to recover impaired instances and to notify via SNS.

NEW QUESTION # 40
A company uses AWS Organizations to create and manage many AWS accounts. The company wants to deploy new IAM roles in each account.
Which action should the SysOps administrator take to deploy the new roles in each of the organization's accounts?

A. Deploy an AWS CloudFormation change set to the organization with a template to create the new IAM roles.
B. Use AWS CloudFormation StackSets to deploy a template to each account to create the new IAM roles.
C. Create a service control policy (SCP) in the organization to add the new IAM roles to each account.
D. Use AWS Config to create an organization rule to add the new IAM roles to each account.

Answer: B

Explanation:
StackSets enables you to create, update, or delete CloudFormation stacks across multiple AWS accounts and regions from a single administrator account, which is ideal for applying identical IAM role configurations across all accounts in an organization. This approach minimizes manual effort, ensures consistency, and scales with the number of accounts. It is the recommended pattern for cross-account resource provisioning within AWS Organizations.

NEW QUESTION # 41
A company uses AWS CloudFormation to manage a stack of Amazon EC2 instances. A CloudOps engineer needs to keep the EC2 instances and their data even if the stack is deleted.
Which solution will meet these requirements?

A. Use Amazon Data Lifecycle Manager (DLM).
B. Create an AWS Backup plan.
C. Set the DeletionPolicy attribute to Retain.
D. Set the DeletionPolicy attribute to Snapshot.

Answer: C

Explanation:
CloudFormation's DeletionPolicy: Retain ensures that resources are not deleted when the stack is deleted.
This preserves both the EC2 instance and any attached storage.
Snapshot does not apply to EC2 instances themselves. Backup solutions do not prevent deletion.
Therefore, Retain is the correct policy.

NEW QUESTION # 42
An Amazon EC2 instance is running an application that uses Amazon Simple Queue Service (Amazon SQS) queues. A CloudOps engineer must ensure that the application can read, write, and delete messages from the SQS queues.
Which solution will meet these requirements in the MOST secure manner?

A. Create and associate an IAM role that allows EC2 instances to call AWS services. Attach an IAM policy to the role that allows sqs:* permissions to the appropriate queues.
B. Create an IAM user with an IAM policy that allows the sqs:SendMessage permission, the sqs:
ReceiveMessage permission, and the sqs:DeleteMessage permission to the appropriate queues. Embed the IAM user's credentials in the application's configuration.
C. Create an IAM user with an IAM policy that allows the sqs:SendMessage permission, the sqs:
ReceiveMessage permission, and the sqs:DeleteMessage permission to the appropriate queues. Export the IAM user's access key and secret access key as environment variables on the EC2 instance.
D. Create and associate an IAM role that allows EC2 instances to call AWS services. Attach an IAM policy to the role that allows the sqs:SendMessage permission, the sqs:ReceiveMessage permission, and the sqs:DeleteMessage permission to the appropriate queues.

Answer: D

Explanation:
The most secure pattern is to use an IAM role for Amazon EC2 with the minimum required permissions.
AWS guidance states: "Use roles for applications that run on Amazon EC2 instances" and "grant least privilege by allowing only the actions required to perform a task." By attaching a role to the instance, short- lived credentials are automatically provided through the instance metadata service; this removes the need to create long-term access keys or embed secrets. Granting only sqs:SendMessage, sqs:ReceiveMessage, and sqs:DeleteMessage against the specific SQS queues enforces least privilege and aligns with CloudOps security controls. Options A and B rely on IAM user access keys, which contravene best practices for workloads on EC2 and increase credential-management risk. Option C uses a role but grants sqs:*, violating least-privilege principles. Therefore, Option D meets the security requirement with scoped, temporary credentials and precise permissions.

NEW QUESTION # 43
A company asks a SysOps administrator to provision an additional environment for an application in four additional AWS Regions. The application is running on more than 100 Amazon EC2 instances in the us-east-
1 Region, using fully configured Amazon Machine Images (AMIs). The company has an AWS CloudFormation template to deploy resources in us-east-1.
What should the SysOps administrator do to provision the application in the MOST operationally efficient manner?

A. Copy the AMI to each Region by using the aws ec2 copy-image command. Update the CloudFormation template to include mappings for the copied AMIs.
B. Run the existing CloudFormation template in each additional Region based on the success of the template that is used currently in us-east-1.
C. Update the CloudFormation template to include the additional Regions in the Auto Scaling group.Update the existing stack in us-east-1.
D. Create a snapshot of the running instance. Copy the snapshot to the other Regions. Create an AMI from the snapshots. Update the CloudFormation template for each Region to use the new AMI.

Answer: A
