NEW QUESTION # 233
A company has several business units that want to use Amazon EC2. The company wants to require all business units to provision their EC2 instances by using only approved EC2 instance configurations.
What should a SysOps administrator do to implement this requirement?
- A. Share an AWS CloudFormation template with the business units. Instruct the business units to pass a role to AWS CloudFormation to allow the service to manage EC2 instances.
- B. Develop an IAM policy that limits the business units to provision EC2 instances only. Instruct the business units to launch instances by using an AWS CloudFormation template.
- C. Publish a product and launch constraint role for EC2 instances by using AWS Service Catalog. Allow the business units to perform actions in AWS Service Catalog only.
- D. Create an EC2 instance launch configuration. Allow the business units to launch EC2 instances by specifying this launch configuration in the AWS Management Console.
Answer: C
Explanation:
To enforce the use of approved EC2 instance configurations across different business units efficiently:
* AWS Service Catalog: Utilize AWS Service Catalog to manage and govern commonly deployed IT
* services. Create a catalog of pre-approved products (in this case, EC2 instance configurations).
* Publish Products: Define and publish EC2 instance configurations as products within the Service Catalog. These products will incorporate all the necessary and approved configurations, options, and software.
* Launch Constraints: Assign launch constraints to these products, ensuring that users can only launch EC2 instances as defined by the pre-approved configurations.
* Control Access: Grant business units access only to the Service Catalog for provisioning EC2 instances.
This ensures they use only those configurations that comply with company policies and standards.
This approach not only standardizes resource deployment but also simplifies management and enhances compliance across the organization.

NEW QUESTION # 236
A company is running Amazon EC2 On-Demand Instances in an Auto Scaling group. The instances process messages from an Amazon Simple Queue Service (Amazon SQS) queue. The Auto Scaling group is set to scale based on the number of messages in the queue. Messages can take up to 12 hours to process completely.
A SysOps administrator must ensure that instances are not interrupted during message processing.
What should the SysOps administrator do to meet these requirements?
- A. Set the Auto Scaling group's termination policy to OldestLaunchConfiguration.
- B. Enable instance scale-in protection for the specific instance in the Auto Scaling group at the start of message processing by calling the Amazon EC2 Auto Scaling API from the processing script. Disable instance scale-in protection after message processing is complete by calling the Amazon EC2 Auto Scaling API from the processing script.
- C. Set the Auto Scaling group's termination policy to OldestInstance.
- D. Suspend the Launch and Terminate scaling processes for the specific instance in the Auto Scaling group at the start of message processing by calling the Amazon EC2 Auto Scaling API from the processing script. Resume the scaling processes after message processing is complete by calling the Amazon EC2 Auto Scaling API from the processing script.
Answer: B
Explanation:
# Enable instance scale-in protection for specific instance.
aws autoscaling set-instance-protection --instance-ids i-5f2e8a0d --auto-scaling-group-name my-asg
--protected-from-scale-in
# Disable instance scale-in protection for the specified instance.
aws autoscaling set-instance-protection --instance-ids i-5f2e8a0d --auto-scaling-group-name my-asg
--no-protected-from-scale-in
https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-instance-protection.html To ensure that EC2 instances in an Auto Scaling group are not interrupted during message processing, the most effective method is to implement scale-in protection for the instances while they are actively processing messages. This can be done programmatically by modifying the Auto Scaling group's settings using the Amazon EC2 Auto Scaling API.
* Starting Message Processing: When an instance begins processing a message, your application should make an API call to enable scale-in protection. This is done using the SetInstanceProtection action, setting the ProtectedFromScaleIn parameter to true for that specific instance.
* Completing Message Processing: Once the message has been processed, another API call should be made to disable scale-in protection. This is done by calling the SetInstanceProtection action again, but this time setting the ProtectedFromScaleIn parameter to false.
This method ensures that while messages are being processed, the instances are not terminated by the Auto Scaling group regardless of any scale-in activities that might be triggered by other parameters like CPU utilization or a decrease in the number of messages in the queue.
AWS Documentation Reference:You can refer to the AWS documentation on managing instance scale-in protection in Auto Scaling groups for more details: Instance Scale-In Protection.

NEW QUESTION # 238
A company uses AWS Organizations to manage multiple AWS accounts with consolidated billing enabled. Organization member account owners want the benefits of Reserved Instances (RIs) but do not want to share RIs with other accounts.
Which solution will meet these requirements?
- A. Purchase RIs in the management account. Disable Rl discount sharing in the management account.
- B. Purchase RIs in individual member accounts. Disable Rl discount sharing in the management account.
- C. Purchase RIs in the management account. Disable Rl discount sharing in the member accounts.
- D. Purchase RIs in individual member accounts. Disable Rl discount sharing in the member accounts.
Answer: B
Explanation:
https://aws.amazon.com/premiumsupport/knowledge-center/ec2-ri-consolidated-billing/ RI discounts apply to accounts in an organization's consolidated billing family depending upon whether RI sharing is turned on or off for the accounts. By default, RI sharing for all accounts in an organization is turned on. The management account of an organization can change this setting by turning off RI sharing for an account. The capacity reservation for an RI applies only to the account the RI was purchased on, no matter whether RI sharing is turned on or off.
NEW QUESTION # 239
A SysOps administrator creates a new source AWS account to use with a company's new application. The application will use Amazon CloudWatch for observability from a monitoring account. The company already used an AWS CloudFormation template to turn on CloudWatch cross-account observability for its other application accounts.
Which combination of steps must the SysOps administrator take to set up the new source account for cross- account observability? (Select THREE.)
- A. Download the CloudFormation template from the new source account.
- B. Add the new source account ID to the monitoring account's configuration policy.
- C. Deploy the CloudFormation stack in the monitoring account.
- D. In the new source account, specify the data that the monitoring account will be able to view.
- E. Download the CloudFormation template from the monitoring account.
- F. Deploy the CloudFormation stack in the new source account.
Answer: B,D,F
Explanation:
AWS CloudWatch cross-account observability allows a central monitoring account to access logs, metrics, and traces from source accounts.
From the Amazon CloudWatch cross-account observability setup guide:
To set up a new source account, you must:
Deploy the CloudFormation template provided by AWS in the source account to configure resource sharing and access.# # C Add the new source account ID to the monitoring account configuration so the monitoring account knows which accounts to observe.# # E In the source account, configure what data types (logs, metrics, traces) will be shared with the monitoring account.# # F
# Why the other options are incorrect:
A/B: You do not download the template from the accounts themselves. AWS provides a template, or your organization reuses an existing one.
D: The template must be deployed in the source account, not the monitoring account.
