Amazon AWS Certified CloudOps Engineer - Associate 認定 SOA-C03 試験問題 (Q310-Q315):

質問 # 310
A company's reporting job that used to run in 15 minutes is now taking an hour to run. An application generates the reports. The application runs on Amazon EC2 instances and extracts data from an Amazon RDS for MySQL database.
A CloudOps engineer checks the Amazon CloudWatch dashboard for the RDS instance and notices that the Read IOPS metrics are high, even when the reports are not running. The CloudOps engineer needs to improve the performance and the availability of the RDS instance.
Which solution will meet these requirements?

A. Create an Amazon CloudFront distribution. Set the RDS instance as the origin. Update the reporting job to query the CloudFront distribution.
B. Increase the size of the RDS instance.
C. Configure an Amazon ElastiCache cluster in front of the RDS instance. Update the reporting job to query the ElastiCache cluster.
D. Deploy an RDS read replica. Update the reporting job to query the reader endpoint.

正解：D

解説：
A read replica offloads read traffic from the primary RDS instance to a separate replica, improving both performance (by reducing read load and IOPS on the primary) and availability (the replica can also be promoted in a failure scenario). Pointing the reporting job to the reader endpoint ensures that heavy reporting reads no longer compete with the primary's transactional workload, reducing query latency and speeding up the reports.

質問 # 311
A CloudOps engineer is preparing to deploy an application to Amazon EC2 instances that are in an Auto Scaling group. The application requires dependencies to be installed. Application updates are issued weekly.
The CloudOps engineer needs to implement a solution to incorporate the application updates on a regular basis. The solution also must conduct a vulnerability scan during Amazon Machine Image (AMI) creation.
What is the MOST operationally efficient solution that meets these requirements?

A. Use EC2 Image Builder with a custom recipe to install the application and dependencies.
B. Invoke the EC2 CreateImage API operation by using an EventBridge scheduled rule.
C. Install the application and dependencies on an EC2 instance and create an AMI.
D. Create a script that uses Packer and schedule a cron job.

正解：A

解説：
EC2 Image Builder is a managed service that automates the creation, testing, vulnerability scanning, and distribution of AMIs. It supports scheduled image pipelines, which makes it ideal for weekly application updates.
Image Builder integrates with Amazon Inspector to perform vulnerability scans during image creation, fulfilling the security requirement. Custom image recipes define application dependencies and installation steps, ensuring consistency across deployments.
Manual AMI creation, cron-based scripts, or direct API calls require ongoing maintenance and do not natively support vulnerability scanning.
Therefore, EC2 Image Builder is the most operationally efficient solution.

質問 # 312
A CloudOps engineer needs to build an event infrastructure for a set of custom application- specific events. The events must be sent to an AWS Lambda function for processing. The CloudOps engineer must record the events to replay later by event type or event time.
Which solution will meet these requirements?

A. Create an archive on the Amazon EventBridge default event bus. Create an EventBridge pipe to ingest the custom events and to save the custom events in the archive. Create a rule to send the custom events to the Lambda function.
B. Create a log group in Amazon CloudWatch Logs. Create an Amazon EventBridge rule to send the custom events to the Lambda function and to the log group.
C. Create an archive on the Amazon EventBridge default event bus. Use pattern matching to record the custom events. Create a rule to send the custom events to the Lambda function.
D. Create an Amazon EventBridge custom event bus. Create an archive on the custom event bus.
Create a rule to send the custom events to the Lambda function.

正解：D

解説：
A custom EventBridge event bus is the correct choice for handling application-specific events.
You can define an archive on that custom event bus to record and later replay events by event type or timestamp. Creating an EventBridge rule to send events to a Lambda function ensures real-time processing while maintaining full replay capability, making this the most flexible and operationally efficient solution.

質問 # 313
A company uses memory-optimized Amazon EC2 instances behind a Network Load Balancer (NLB) to run an application. The company launched the EC2 instances from an AWS-provided Red Hat Enterprise Linux (RHEL) AMI.
A CloudOps engineer must monitor RAM utilization in 5-minute intervals. The CloudOps engineer must ensure that the EC2 instances scale in and out appropriately based on incoming load.
Which solution will meet these requirements?

A. Configure detailed monitoring for the EC2 instances. Configure the Amazon CloudWatch agent on the EC2 instances. Create an EC2 Auto Scaling group and Auto Scaling policy that is based on the mem_active metric.
B. Configure basic monitoring for the EC2 instances. Use the standard mem_used_percent metric for monitoring. Create an EC2 Auto Scaling group and Auto Scaling policy that is based on the mem_used_percent metric.
C. Configure detailed monitoring for the EC2 instances. Use the mem_used_percent metric that the detailed monitoring feature provides. Create an IAM role that allows the CloudWatch agent to upload data. Create an EC2 Auto Scaling group and Auto Scaling policy that is based on the mem_used_percent metric.
D. Configure basic monitoring for the EC2 instances. Configure the Amazon CloudWatch agent on the EC2 instances. Create an IAM role that allows the CloudWatch agent to upload data. Create an EC2 Auto Scaling group and Auto Scaling policy that is based on the mem_used_percent metric.

正解：D

解説：
EC2 does not publish RAM utilization as a native CloudWatch metric by default. Memory metrics such as mem_used_percent are typically collected by the CloudWatch Agent, which runs on the instance and publishes custom metrics to CloudWatch. Because the requirement is RAM utilization at 5-minute intervals, the CloudWatch Agent can be configured to emit metrics at that cadence (or faster).
"Detailed monitoring" for EC2 mainly affects EC2-provided metrics (like CPU) by changing the period from 5 minutes (basic) to 1 minute (detailed). It does not magically provide memory utilization. Therefore, the key requirement is installing/configuring the CloudWatch Agent and ensuring it has permissions to publish metrics (via an IAM role attached to the instance / instance profile).

質問 # 314
A company uses AWS Organizations to manage a set of AWS accounts. The company has set up organizational units (OUs) in the organization. An application OU supports various applications.
A CloudOps engineer must prevent users from launching Amazon EC2 instances that do not have a CostCenter-Project tag into any account in the application OU. The restriction must apply only to accounts in the application OU.
Which solution will meet these requirements?

A. Create an IAM group that has a policy that allows the ec2:RunInstances action when the CostCenter-Project tag is present. Place all IAM users who need access to the application accounts in the IAM group.
B. Create an IAM role that has a policy that allows the oc2:RunInstances action when the CostCenter-Project tag is present. Attach the IAM role to the IAM users that are in the application OU accounts.
C. Create a service control policy (SCP) that denies the oc2:RunInstances action when the CostCenter-Project tag is missing. Attach the SCP to the application OU.
D. Create a service control policy (SCP) that denies the ec2:RunInstances action when the CostCenter-Project tag is missing. Attach the SCP to the root OU.

正解：C

解説：
To enforce a mandatory tag across multiple accounts in an OU, you use a service control policy.
An SCP with a Deny on ec2:RunInstances when the CostCenter-Project tag is not present will block launches of untagged instances in all accounts in that OU, regardless of local IAM policies.
Attaching it to the application OU ensures the restriction applies only there and not to other OUs or the entire organization.
