Amazon AWS Certified CloudOps Engineer - Associate Sample Questions (Q42-Q47):

NEW QUESTION # 42
A company uses an IAM policy to ensure that all AWS resources are deployed and managed by AWS CloudFormation. A CloudOps engineer must periodically audit all AWS resources and provide a list of resources that do not match the expected configuration.
Which solution will meet this requirement with the LEAST effort?

A. Audit code repositories where CloudFormation code is stored to look for any deviations from the expected configuration.
B. Configure an Amazon EventBridge rule that sends a notification to the company when any resource is created by CloudFormation. Audit the event notifications for any incorrect configurations.
C. Use the AWS CLI to check all resources to ensure consistency with the intended configuration.
D. Use Amazon EventBridge to schedule periodic invocations of CloudFormation drift detection. Capture findings for review.

Answer: D

Explanation:
CloudFormation drift detection compares the actual configuration of stack resources with the expected configuration defined in the CloudFormation template. This directly satisfies the requirement to find resources that do not match the expected configuration. Scheduling drift detection with Amazon EventBridge automates the audit and avoids manual CLI checks or repository reviews. Repository reviews only validate desired template code, not the real deployed state. EventBridge notifications about resource creation do not prove that resources remain compliant after deployment. AWS CLI scripts could work, but they would require custom logic and ongoing maintenance. For CloudOps, the best approach is to use the native drift detection capability and automate it on a schedule, then capture the drift results for operational review and remediation planning.

NEW QUESTION # 43
A SysOps administrator must load test a new Amazon CloudFront distribution to assess data transfer and latency performance. Which solution will meet this requirement?

A. Send client requests from multiple geographic regions. Configure the load test so that each client makes an identical DNS request. Focus the client requests on the IP address that the DNS returns.
B. Send client requests from a single geographic region. Configure the load test so that each client makes an identical DNS request. Focus the client requests on the IP address that the DNS returns.
C. Send client requests from a single geographic region. Configure the load test so that each client makes an independent DNS request. Spread the client requests across the set of IP addresses that the DNS returns.
D. Send client requests from multiple geographic regions. Configure the load test so that each client makes an independent DNS request. Spread the client requests across the set of IP addresses that the DNS returns.

Answer: D

Explanation:
Comprehensive and Detailed Explanation From Exact Extract of AWS CloudOps Documents:
CloudFront is a global edge network service, and its performance (latency and data transfer behavior) depends heavily on the geographic location of viewers and the edge locations that serve them. Therefore, a valid load test must generate traffic from multiple geographic regions to reflect real user distribution and to measure end- to-end latency across diverse network paths.
Additionally, CloudFront uses DNS to return multiple possible edge IP addresses and can direct clients to different edge locations based on resolver behavior and network conditions. For a realistic test, each client should make an independent DNS request and distribute traffic across the returned IP addresses, rather than pinning all load to a single IP. Spreading requests across the returned set avoids biasing the test to one edge path and better represents how real browsers and applications resolve and connect to CloudFront.
Options A and B fail to model global viewer behavior because they test from only one region. Option C introduces an unrealistic constraint by forcing identical DNS resolution and concentrating load on a single IP address, which can distort latency and throughput results. Option D best matches CloudOps guidance for performance validation of CDN workloads: multi-region testing with realistic DNS resolution and traffic distribution.

NEW QUESTION # 44
A company hosts a static website in Amazon S3 behind an Amazon CloudFront distribution. When new versions are deployed, users sometimes do not see updated content immediately.
Which solution will meet this requirement?

A. Create a CloudFront invalidation.
B. Attach the CachingOptimized managed cache policy to the distribution.
C. Modify the distribution settings to specify the protocol as HTTPS only.
D. Configure the CloudFront distribution to add a custom Cache-Control header to requests for content from the S3 bucket.

Answer: A

Explanation:
The AWS Cloud Operations and Content Delivery documentation explains that Amazon CloudFront caches objects in edge locations for a defined time based on TTL settings or origin headers. When new content is deployed to the S3 origin, previously cached versions remain in edge caches until they expire.
To immediately serve the new version, CloudOps engineers must initiate a CloudFront invalidation, which removes cached objects from all edge locations. This forces CloudFront to fetch the latest version from the origin (S3).
Invalidations can target individual objects (e.g., /index.html) or wildcard paths (e.g., /*) and are the AWS-recommended approach for dynamic content refresh after static site updates.
Changing headers (Option A), enforcing HTTPS (Option B), or applying caching policies (Option C) do not directly refresh outdated cache content.
Thus, Option D - issuing a CloudFront invalidation - ensures users receive the latest website content immediately after deployment.

NEW QUESTION # 45
A company runs several workloads on AWS. The company identifies five AWS Trusted Advisor service quota metrics to monitor in a specific AWS Region. The company wants to receive email notifications each time resource usage exceeds 60% of one of the service quotas.
Which solution will meet these requirements?

A. Use the AWS Health Dashboard to monitor each Trusted Advisor service quota metric. Configure an Amazon SNS topic for email notification.
B. Use the AWS Health Dashboard to monitor each Trusted Advisor service quota metric. Configure an Amazon SQS queue for email notification.
C. Create five Amazon CloudWatch alarms, one for each Trusted Advisor service quota metric. Configure an Amazon Simple Queue Service (Amazon SQS) queue for email notification.
D. Create five Amazon CloudWatch alarms, one for each Trusted Advisor service quota metric. Configure an Amazon Simple Notification Service (Amazon SNS) topic for email notification each time that usage exceeds 60% of one of the service quotas.

Answer: D

Explanation:
Comprehensive Explanation (250-350 words):
AWS Trusted Advisor publishes service quota metrics to Amazon CloudWatch. These metrics can be monitored using CloudWatch alarms, which support threshold-based alerting. By creating a CloudWatch alarm for each service quota metric, the CloudOps engineer can trigger alerts when usage exceeds 60%.
Amazon SNS is the AWS-native service for email notifications. CloudWatch alarms integrate directly with SNS, making this the most straightforward solution. SNS supports email subscriptions without additional infrastructure.
Options B and C incorrectly use SQS for email notifications, which requires additional processing and does not natively send emails. Option D relies on the AWS Health Dashboard, which does not support configurable threshold-based alerts for service quotas.
Therefore, CloudWatch alarms combined with SNS provide the correct and most efficient solution.

NEW QUESTION # 46
A company hosts an FTP server on EC2 instances. AWS Security Hub sends findings to Amazon EventBridge when the FTP port becomes publicly exposed in attached security groups.
A CloudOps engineer needs an automated, event-driven remediation solution to remove public access from security groups.
Which solution will meet these requirements?

A. Configure the existing EventBridge event to stop the EC2 instances that have the exposed port.
B. Create a cron job for the FTP server that invokes an AWS Lambda function. Configure the Lambda function to modify the server to use SFTP instead of FTP.
C. Create a cron job for the FTP server to invoke an AWS Lambda function. Configure the Lambda function to modify the security group of the identified EC2 instances and to remove the instances that allow public access.
D. Configure the existing EventBridge event to invoke an AWS Lambda function. Configure the function to remove the security group rule that allows public access.

Answer: D

Explanation:
Per the AWS Cloud Operations and Security Automation documentation, Security Hub integrates with Amazon EventBridge to publish findings in real time. These events can trigger automated responses using AWS Lambda functions or AWS Systems Manager Automation runbooks.
In this scenario, the correct CloudOps approach is to configure the existing EventBridge rule to invoke a Lambda function that inspects the event payload, identifies the affected security group, and removes the offending inbound rule (e.g., port 21 open to 0.0.0.0/0).
This event-driven remediation provides continuous compliance and eliminates manual intervention. Cron jobs (Options B and C) contradict event-driven design and add operational overhead. Stopping instances (Option A) doesn't address the root cause - the insecure security group.
Thus, Option D aligns with AWS best practices for automated security remediation through EventBridge and Lambda.
