Amazon AWS Certified SysOps Administrator - Associate (SOA-C02) Sample Questions (Q244-Q249):

NEW QUESTION # 244
A team of developers is using several Amazon S3 buckets as centralized repositories. Users across the world upload large sets of files to these repositories. The development team's applications later process these files.
A SysOps administrator sets up a new S3 bucket. DOC-EXAMPLE-BUCKET, to support a new workload. The new S3 bucket also receives regular uploads of large sets of files from users worldwide. When the new S3 bucket is put into production, the upload performance from certain geographic areas is lower than the upload performance that the existing S3 buckets provide.
What should the SysOps administrator do to remediate this issue?

  • A. Use S3 multipart upload for the new S3 bucket. Verify that the developers are using Region-specific S3 endpoint names such as D0C-EXAMPLE-BUCKET.s3. [RegionJ.amazonaws.com in their API calls.
  • B. Add the new S3 bucket to a new Amazon CloudFront distribution. Provide the developers with the domain name of the new distribution for use in their API calls.
  • C. Enable S3 Transfer Acceleration for the new S3 bucket. Verify that the developers are using the DOC-EXAMPLE-BUCKET.s3-accelerate.amazonaws.com endpoint name in their API calls.
  • D. Provision an Amazon ElasliCache for Redis cluster for the new S3 bucket. Provide the developers with the configuration endpoint of the cluster for use in their API calls.

Answer: C

Explanation:
For improving upload performance globally for an Amazon S3 bucket, enabling S3 Transfer Acceleration is the best solution. This service optimizes file transfers to S3 using Amazon CloudFront's globally distributed edge locations. After enabling this feature, uploads to the S3 bucket are first routed to an AWS edge location and then transferred to S3 over an optimized network path. Option C is correct, and the developers should use the provided accelerate endpoint in their API calls. For more details, consult the AWS documentation on S3 Transfer Acceleration Amazon S3 Transfer Acceleration.


NEW QUESTION # 245
A company runs its applications on a large number of Amazon EC2 instances. A SysOps administrator must implement a solution to notify the operations team whenever an EC2 instance slate changes.
What is the MOST operationally efficient solution that meets these requirements?

  • A. Create an Amazon EventBridge event rule that captures EC2 instance state changes. Set as the target an AWS Lambda function that publishes a notification to an Amazon Simple Notification Service (Amazon SNS) topic.
  • B. Create a script that captures instance state changes and publishes a notification to an Amazon Simple Notification Service (Amazon SNS) topic. Use AWS Systems Manager Run Command to run the script on all EC2 instances.
  • C. Create an AWS Config custom rule that evaluates instance state changes with automatic remediation. Use the rule to invoke an AWS Lambda function that publishes a notification to an Amazon Simple Notification Service (Amazon SNS) topic.
  • D. Create an Amazon EventBridge event rule that captures EC2 instance state changes. Set an Amazon Simple Notification Service (Amazon SNS) topic as the target.

Answer: D

Explanation:
The most operationally efficient way to monitor state changes in EC2 instances and notify the operations team is by using Amazon EventBridge. EventBridge can be configured with a rule that listens for state change events from EC2 instances. These events can then be directed to an Amazon Simple Notification Service (Amazon SNS) topic, which will distribute the notification to the relevant parties. This solution does not require deploying additional scripts or functions, thereby enhancing operational efficiency. Option B is correct. For more details, see the Amazon EventBridge documentation Amazon EventBridge.


NEW QUESTION # 246
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. 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.
  • B. 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.
  • C. Set the Auto Scaling group's termination policy to OldestLaunchConfiguration.
  • D. Set the Auto Scaling group's termination policy to OldestInstance.

Answer: A

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 # 248
A company has a stateful web application that is hosted on Amazon EC2 instances in an Auto Scaling group. The instances run behind an Application Load Balancer (ALB) that has a single target group. The ALB is configured as the origin in an Amazon CloudFront distribution. Users are reporting random logouts from the web application.
Which combination of actions should a SysOps administrator take to resolve this problem? (Select TWO.)

  • A. Configure header forwarding in the CloudFront distribution cache behavior.
  • B. Change to the least outstanding requests algorithm on the ALB target group.
  • C. Enable group-level stickiness on the ALB listener rule.
  • D. Configure cookie forwarding in the CloudFront distribution cache behavior.
  • E. Enable sticky sessions on the ALB target group.

Answer: D,E

Explanation:
Reference:
https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Cookies.html You can configure each cache behavior to do one of the following: Forward all cookies to your origin - CloudFront includes all cookies sent by the viewer when it forwards requests to the origin. https://docs.aws.amazon.com/elasticloadbalancing/latest/application/sticky-sessions.html By default, an Application Load Balancer routes each request independently to a registered target based on the chosen load-balancing algorithm.
