Amazon AWS Certified SysOps Administrator - Associate (SOA-C02) Sample Questions (Q458-Q463):
NEW QUESTION # 458
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?
Answer: C
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 # 459
A company's security policy requires incoming SSH traffic to be restricted to a defined set of addresses. The company is using an AWS Config rule to check whether security groups allow unrestricted incoming SSH traffic.
A SysOps administrator discovers a noncompliant resource and fixes the security group manually. The SysOps administrator wants to automate the remediation of other noncomphant resources.
What is the MOST operationally efficient solution that meets these requirements?
Answer: B
Explanation:
* Objective:
* Automate remediation of security groups that allow unrestricted SSH access.
* Using AWS Config Automatic Remediation:
* AWS Config allows rules to have automatic remediation actions.
* The remediation action AWS-DisableIncomingSSHOnPort22 is a managed action specifically designed to restrict unrestricted SSH access.
* Steps to Implement:
* Step 1: Open the AWS Config console.
* Step 2: Identify the rule that checks for unrestricted SSH access (e.g., security-group-restricted- ssh).
* Step 3: Enable automatic remediation:
* Attach the managed remediation action AWS-DisableIncomingSSHOnPort22 to the rule.
* Specify necessary IAM roles and permissions for the remediation action.
* Step 4: Test the rule and remediation action on a noncompliant security group.
* AWS References:
* AWS Config Managed Rules:AWS Config Rules
* Automatic Remediation:AWS Config Remediation
* Why Other Options Are Incorrect:
* Option A: Requires manual configuration of alarms and Lambda functions, which is less operationally efficient than using managed remediation.
* Option C and D: Custom Lambda functions and EventBridge rules are unnecessary when AWS provides a managed remediation action.
NEW QUESTION # 460
A company has developed a service that is deployed on a fleet of Linux-based Amazon EC2 instances that are in an Auto Scaling group. The service occasionally fails unexpectedly because of an error in the application code. The company's engineering team determines that resolving the underlying cause of the service failure could take several weeks.
A SysOps administrator needs to create a solution to automate recovery if the service crashes on any of the EC2 instances.
Which solutions will meet this requirement? (Select TWO.)
Answer: C,E
Explanation:
The requirement is to automate recovery if the service crashes on any of the EC2 instances.
Option A: Install the Amazon CloudWatch agent on the EC2 instances. Configure the CloudWatch agent to monitor the service. Set the CloudWatch action to restart if the service health check fails . This is a valid solution because the CloudWatch agent can be configured to monitor the service and take action (restart the service) if the health check fails .
Option C: Tag the EC2 instances. Use AWS Systems Manager State Manager to create an association that uses the AWS-RunShellScript document. Configure the association command with a script that checks if the service is running and that starts the service if the service is not running. For targets, specify the EC2 instance tag. Schedule the association to run every 5 minutes678. This is a valid solution because AWS Systems Manager State Manager can be used to maintain a consistent state of the EC2 instances. It can run a script to check if the service is running and start the service if it's not running678.
Option B: Tag the EC2 instances. Create an AWS Lambda function that uses AWS Systems Manager Session Manager to log in to the tagged EC2 instances and restart the service. Schedule the Lambda function to run every 5 minutes . This is not a valid solution because AWS Lambda functions are not designed to log in to EC2 instances and restart services. They are used for running serverless applications.
Option D: Update the EC2 user data that is specified in the Auto Scaling group's launch template to include a script that runs on a cron schedule every 5 minutes131415. This is not a valid solution because user data scripts are run only during the launch of an EC2 instance. They are not designed to run on a schedule.
Option E: Update the EC2 user data that is specified in the Auto Scaling group's launch template to ensure that the service runs during startup. Redeploy all the EC2 instances in the Auto Scaling group with the updated launch template131416. This is not a valid solution because while user data can be used to ensure that the service runs during startup, it does not provide a solution for when the service crashes after the EC2 instance has started.
NEW QUESTION # 461
A company needs to automatically monitor an AWS account for potential unauthorized AWS Management Console logins from multiple geographic locations.
Which solution will meet this requirement?
Answer: B
Explanation:
Amazon GuardDuty is a threat detection service that continuously monitors for malicious activity and unauthorized behavior to protect AWS accounts and workloads. It provides detailed monitoring for unauthorized access attempts, including console login attempts from unusual locations.
* Amazon GuardDuty:
* GuardDuty analyzes VPC flow logs, AWS CloudTrail logs, and DNS logs to detect suspicious activity.
* It generates findings, such as UnauthorizedAccess
/ConsoleLoginSuccess, to alert administrators about potential security issues.
* Setup:
* Enable GuardDuty in your AWS account.
* Configure GuardDuty to monitor unauthorized console logins.
* Set up notifications for the relevant findings to alert administrators.
References:
* Amazon GuardDuty
* GuardDuty Finding Types
NEW QUESTION # 462
A company's SysOps administrator maintains a highly available environment. The environment includes Amazon EC2 instances and an Amazon RDS Multi-AZ database. The EC2 instances are in an Auto Scaling group behind an Application Load Balancer.
Recently, the company conducted a failover test. The SysOps administrator needs to decrease the failover time of the RDS database by at least 10%.
Which solution will meet this requirement?
Answer: A
Explanation:
With RDS Proxy, failover times for Aurora and RDS databases are reduced by up to 66%.
