Amazon AWS Certified CloudOps Engineer - Associate SOA-C03 Prüfungsfragen mit Lösungen (Q187-Q192):

187. Frage
A company is using AWS Certificate Manager (ACM) to manage public SSL/TLS certificates. A CloudOps engineer needs to send an email notification when a certificate has less than 14 days until expiration.
Which solution will meet this requirement with the LEAST operational overhead?

A. Create an Amazon EventBridge rule that has an event source of aws.acm. Configure the rule to evaluate the DaysToExpiry metric for all ACM certificates. Configure the rule to send an event to a target Amazon SNS topic if DaysToExpiry is less than 14. Subscribe the appropriate email addresses to the SNS topic.
B. Create an Amazon CloudWatch dashboard that displays the DaysToExpiry metric for all ACM certificates. If DaysToExpiry is less than 14, send an email message to the appropriate email addresses.
Send the email message by running a predefined CLI command to publish to an Amazon SNS topic.
C. Create an Amazon CloudWatch custom metric to monitor certificate expiration for all ACM certificates. Create an Amazon EventBridge rule that has an event source of aws.cloudwatch. Configure the rule to send an event to a target Amazon SNS topic if the DaysToExpiry metric is less than 14.
Subscribe the appropriate email addresses to the SNS topic.
D. Create an Amazon EventBridge rule that has an event source of aws.acm. Configure the rule to evaluate the DaysToExpiry metric for all ACM certificates. Configure a target SMS identity that uses a predefined email template. Configure the rule to send an event to the target SMS identity if DaysToExpiry is less than 14.

Antwort: C

Begründung:
AWS Certificate Manager publishes certificate-expiration visibility through the DaysToExpiry metric, which can be monitored through Amazon CloudWatch. The operationally correct pattern is to create a CloudWatch alarm when DaysToExpiry drops below the required threshold and notify subscribers through Amazon SNS.
Among the provided options, option A is the closest valid implementation because it uses CloudWatch-based metric evaluation and SNS email notification. Option B is weak because EventBridge does not directly
"evaluate" CloudWatch metric thresholds from the ACM event source. Option C requires manual dashboard monitoring and CLI action, which is not operationally efficient. Option D incorrectly references an SMS identity instead of SNS email notification. For CloudOps, automated metric-based alerting is preferred because it reduces manual certificate tracking and prevents unexpected TLS expiration incidents.

188. Frage
A company uses AWS Systems Manager to automate common operational tasks across its AWS resources. The company wants to automatically collect software inventory of all its Amazon EC2 instances every day. The solution must store the data in an Amazon S3 bucket for auditing purposes. Which solution will meet these requirements?

A. Set up Systems Manager Session Manager to connect to EC2 instances. Use Systems Manager Fleet Manager to aggregate inventory results across the environment.
B. Configure Systems Manager Patch Manager to deploy inventory collection agents. Configure Systems Manager Compliance to validate inventory data.
C. Create a Systems Manager association with the AWS-GatherSoftwareInventory document.
Schedule the association to run every day on all EC2 instances.
D. Configure Systems Manager Distributor to package inventory collection software. Use Systems Manager Hybrid Activations to scan the inventory every day.

Antwort: C

Begründung:
Systems Manager Inventory is configured through State Manager associations that run inventory collection documents such as AWS-GatherSoftwareInventory. AWS documentation states that configuring inventory collection starts by creating a Systems Manager State Manager association, and Systems Manager collects inventory data when the association runs. Inventory data can be synchronized to an Amazon S3 bucket for auditing and reporting. This directly meets the requirement to collect software inventory every day and store the results in S3. Distributor packages and distributes software; it is not the primary inventory collection mechanism. Patch Manager manages patching, not daily software inventory exports. Session Manager and Fleet Manager are useful for access and fleet visibility but do not provide the scheduled inventory-to-S3 workflow. Therefore, a scheduled Systems Manager association is correct.

189. Frage
A company is migrating a legacy application to AWS. The application runs on EC2 instances across multiple Availability Zones behind an Application Load Balancer (ALB). The target group routing algorithm is set to weighted random, and the application requires session affinity (sticky sessions).
After deployment, users report random application errors that were not present before migration, even though target health checks are passing.
Which solution will meet this requirement?

A. Turn on anomaly mitigation for the target group.
B. Turn off the cross-zone load balancing attribute of the target group.
C. Set the routing algorithm of the target group to least outstanding requests.
D. Increase the deregistration delay attribute of the target group.

Antwort: C

Begründung:
According to the AWS Cloud Operations and Elastic Load Balancing documentation, Application Load Balancer (ALB) supports multiple routing algorithms to distribute requests among targets:
Round robin (default)
Least outstanding requests (LOR)
Weighted random
When applications require session affinity, AWS recommends using "least outstanding requests" as the load balancing algorithm because it reduces latency, distributes load evenly, and ensures consistent target responsiveness during high traffic.
Using weighted random routing with sticky sessions can cause sessions to be routed inconsistently if one target's capacity fluctuates, leading to session mismatches and application errors - especially when user sessions rely on instance-specific state.
Disabling cross-zone balancing (Option C) or adjusting deregistration delay (Option D) does not address routing inconsistency. Anomaly mitigation (Option B) protects against target performance degradation, not sticky-session misrouting.
Therefore, the correct solution is Option A - changing the target group's routing algorithm to least outstanding requests ensures smoother, predictable session handling and resolves random application errors.

190. Frage
The company uses AWS Organizations to manage its accounts. For the production account, a SysOps administrator must ensure that all data is backed up daily for all current and future Amazon EC2 instances and Amazon Elastic File System (Amazon EFS) file systems. Backups must be retained for 30 days.
Which solution will meet these requirements with the LEAST amount of effort?

A. Create a lifecycle policy in Amazon Data Lifecycle Manager (Amazon DLM). Assign all resources by resource ID, selecting all existing EC2 and EFS resources that are running in the account. Edit the lifecycle policy daily to include any new resources. Schedule the lifecycle policy to create snapshots every day with a retention period of 30 days.
B. Create a backup plan in AWS Backup. Assign resources by resource ID, selecting all existing EC2 and EFS resources that are running in the account. Edit the backup plan daily to include any new resources. Schedule the backup plan to run every day with a lifecycle policy to expire backups after 30 days.
C. Create a lifecycle policy in Amazon Data Lifecycle Manager (Amazon DLM). Assign all resources by tags. Ensure that all existing EC2 and EFS resources are tagged correctly. Apply a service control policy (SCP) that prevents resource creation unless the correct tags are applied. Schedule the lifecycle policy to create snapshots every day with a retention period of 30 days.
D. Create a backup plan in AWS Backup. Assign resources by tags. Ensure that all existing EC2 and EFS resources are tagged correctly. Apply a service control policy (SCP) for the production account OU that prevents instance and file system creation unless the correct tags are applied.
Schedule the backup plan to run every day with a lifecycle policy to expire backups after 30 days.

Antwort: D

Begründung:
AWS Backup supports both EC2 and EFS natively. (Amazon DLM does not support EFS backups
- that rules out C and D right away.)
Using tags instead of listing individual resource IDs means you don't have to edit the plan every time someone launches a new instance or creates a new file system.
Adding an SCP that enforces tagging at creation guarantees that all future resources are automatically included in backups.
You can set the plan to run daily and expire after 30 days - exactly what's required.

191. Frage
A company deploys AWS infrastructure in a VPC that has an internet gateway. The VPC has public subnets and private subnets. An Amazon RDS for MySQL DB instance is deployed in a private subnet. An AWS Lambda function uses the same private subnet and connects to the DB instance to query data.
A developer modifies the Lambda function to require the function to publish messages to an Amazon Simple Queue Service (Amazon SQS) queue. After these changes, the Lambda function times out when it tries to publish messages to the SQS queue.
Which solutions will resolve this issue? (Select TWO.)

A. Deploy an RDS proxy. Configure the Lambda function to connect to the DB instance through the proxy.
B. Reconfigure the Lambda function so that the function is not connected to the VPC.
C. Create a gateway endpoint for Amazon SQS in the VPC.
D. Create an interface VPC endpoint for Amazon SQS in the VPC.
E. Deploy a NAT gateway. Update the private subnet's route table to route all traffic to the NAT gateway.

Antwort: D,E

Begründung:
Comprehensive Explanation (250-350 words):
When an AWS Lambda function is configured to run inside a VPC, it loses default internet access. All outbound traffic must be explicitly routed. In this scenario, the Lambda function resides in a private subnet and successfully connects to Amazon RDS, but it times out when attempting to publish messages to Amazon SQS. This indicates a lack of network connectivity to the SQS service endpoint.
There are two valid AWS-supported ways to restore connectivity. The first is to deploy a NAT gateway in a public subnet and update the private subnet route table to send outbound internet-bound traffic (0.0.0.0/0) to the NAT gateway. This allows the Lambda function to reach public AWS service endpoints, including SQS.
The second option is to create an interface VPC endpoint (AWS PrivateLink) for Amazon SQS. This enables private, secure connectivity to SQS directly within the AWS network without traversing the internet.
This approach is often preferred for security-sensitive workloads and removes dependency on NAT gateways.
Option A would break database connectivity because the Lambda function must remain in the VPC to access the private RDS instance. Option B does not address outbound connectivity to SQS. Option E is incorrect because Amazon SQS does not support gateway endpoints; only interface endpoints are supported.
Therefore, deploying a NAT gateway or creating an SQS interface endpoint resolves the timeout issue.
