Amazon AWS Certified CloudOps Engineer - Associate 認定 SOA-C03 試験問題 (Q220-Q225):

質問 # 220
A CloudOps engineer is troubleshooting an implementation of Amazon CloudWatch Synthetics.
The CloudWatch Synthetics results must be sent to an Amazon S3 bucket.
The CloudOps engineer has copied the configuration of an existing canary that runs on a VPC that has an internet gateway attached. However, the CloudOps engineer cannot get the canary to successfully start on a private VPC that has no internet access.
What should the CloudOps engineer do to successfully run the canary on the private VPC?

A. Ensure that the DNS resolution option and the DNS hostnames option are turned on in the VPC.
Create an interface VPC endpoint for CloudWatch. Create a gateway VPC endpoint for Amazon S3. Add the permissions to allow CloudWatch Synthetics to use both endpoints.
B. Ensure that the DNS resolution option and the DNS hostnames option are turned on in the VPC.
Add the synthetics:GetCanaryRuns permission to the VPC. On the S3 bucket, add the IgnorePublicAcls permission to the CloudWatch Synthetics role.
C. Ensure that the DNS resolution option and the DNS hostnames option are turned off in the VPC.
Create a gateway VPC endpoint for Amazon S3. Add the permissions to allow CloudWatch Synthetics to use the S3 endpoint.
D. Ensure that the DNS resolution option and the DNS hostnames option are turned off in the VPC.
Add a security group to the canary to allow outbound traffic on the DNS port. Add the permissions to allow CloudWatch Synthetics to write to the S3 bucket.

正解：A

解説：
When a CloudWatch Synthetics canary runs inside a private VPC, it must access CloudWatch and S3 privately for publishing logs, metrics, and storing results. Because there is no internet access, the canary requires:
- DNS resolution and hostnames enabled for proper endpoint resolution.
- An interface VPC endpoint for CloudWatch, so the canary can communicate with the CloudWatch service privately.
- A gateway VPC endpoint for S3, to allow results to be written to the S3 bucket without internet access.

質問 # 221
A CloudOps engineer has an Amazon ECS service that runs a transaction processing application.
The CloudOps engineer needs to deploy a new feature on the ECS service. The feature cannot have downtime during deployment. The feature must also have the ability to run an immediate one-step rollback if a performance-degrading bug is detected. Which solution will meet these requirements?

A. Configure the ECS service with a minimum healthy percentage of 100%. Use the default rolling update deployment type.
B. Implement a blue/green deployment by using AWS CodeDeploy.
C. Set the ECS service's desired count to double the current size. Manually terminate the old tasks after the new tasks are registered.
D. Configure a canary deployment by using an AWS CodeDeploy linear traffic shift with a 10% increment over 10 minutes.

正解：B

解説：
Blue/green deployment with AWS CodeDeploy is the correct strategy for Amazon ECS when zero downtime and fast rollback are required. In a blue/green deployment, the current production task set remains active while a new task set is created and validated. Traffic can then be shifted safely to the new version. If the new version causes performance degradation, CodeDeploy can roll back by redirecting traffic to the previous task set. AWS ECS documentation describes blue/green deployment as a method that reduces downtime and risk by running two production environments and validating revisions before routing production traffic. Rolling updates do not provide the same immediate one-step rollback. Canary or linear traffic shifting gradually moves traffic but does not match the requirement for immediate rollback as directly as blue/green.
Manual scaling is operationally weak.

質問 # 222
A company has deployed Amazon EC2 instances from custom Amazon Machine Images (AMIs) in two AWS Regions. The company registered all the instances with AWS Systems Manager.
The company discovers that the operating system on some instances has a significant zero-day exploit.
However, the company does not know how many instances are affected.
A CloudOps engineer must implement a solution to deploy operating system patches for the affected EC2 instances.
Which solution will meet this requirement with the LEAST operational overhead?

A. Define a patch baseline in Systems Manager Patch Manager. Use a Patch Manager scan to identify the affected instances. Use the Patch Now option in each Region to update the affected instances.
B. Use AWS Config to identify the affected instances. Update the existing EC2 AMIs with the desired patch. Manually launch instances from the new AMIs to replace the affected instances in both Regions.
C. Use AWS Config to identify the affected instances. Define a patch baseline in Systems Manager Patch Manager. Use the Patch Now option in Patch Manager to update the affected instances.
D. Create an Amazon EventBridge rule to react to Systems Manager Compliance events. Configure the EventBridge rule to run a patch baseline on the affected instances.

正解：A

解説：
Because all instances are already managed by AWS Systems Manager, the lowest-overhead approach is to use Systems Manager Patch Manager end-to-end. Patch Manager is built specifically to scan managed instances for missing patches and to apply operating system patches according to defined rules. By defining a patch baseline, the CloudOps engineer establishes which patches are approved (and how quickly critical patches are approved), plus any exclusions and compliance rules. A Patch Manager scan can then be run to determine which instances are noncompliant and therefore likely affected by the vulnerability, without the engineer needing to manually inventory hosts.
After identifying affected (noncompliant) instances through the scan results, Patch Manager can apply patches directly using Patch Now (or an equivalent on-demand patch operation) in each Region. This matches the multi-Region requirement while keeping operations simple: no custom code, no additional services, and no complex event orchestration. It also produces compliance visibility in Systems Manager, which helps track remediation status for incident response.
Option B adds AWS Config unnecessarily. AWS Config is useful for recording and evaluating configuration changes and can report compliance against configuration rules, but it is not the most direct tool for identifying missing OS patches on instances already under Systems Manager management. Option C introduces additional moving parts (EventBridge rules and event-driven automation). While it can be powerful, it is more complex than a straightforward Patch Manager scan-and-patch workflow, and it assumes the right compliance events exist for this scenario before remediation begins. Option D is the highest operational burden because it requires rebuilding AMIs, launching replacement instances, and coordinating replacements across two Regions. That approach aligns to immutable infrastructure patterns, but it is not the least overhead for rapid remediation of existing instances.
Therefore, using Patch Manager with a patch baseline, scanning to identify affected instances, and applying patches in each Region is the simplest and most operationally efficient solution.

質問 # 223
A SysOps administrator creates a custom Amazon Machine Image (AMI) in the eu-west-2 Region and uses the AMI to launch Amazon EC2 instances. The SysOps administrator needs to use the same AMI to launch EC2 instances in two other Regions: us-east-1 and us-east-2.
What must the SysOps administrator do to use the custom AMI in the additional Regions?

A. Copy the AMI to the additional Regions
B. Share the AMI to the additional Regions. Assign the required access permissions.
C. Make the AMI public in the Community AMIs section of the AWS Management Console
D. Copy the AMI to a new Amazon S3 bucket. Assign access permissions to the AMI for the additional Regions

正解：A

解説：
Amazon Machine Images (AMIs) are Region-specific resources. AWS CloudOps documentation explicitly states that an AMI created in one Region cannot be used to launch instances in another Region unless it is copied to the target Region. Therefore, the SysOps administrator must copy the AMI to both us-east-1 and us-east-2.
The AMI copy process creates a new AMI in each destination Region and automatically copies the underlying snapshots. Once the AMIs exist in the target Regions, they can be referenced in launch templates, Auto Scaling groups, or AWS CloudFormation templates for consistent multi- Region deployments.

質問 # 224
A CloudOps engineer wants to share a copy of a production database with a migration account. The production database is hosted on an Amazon RDS DB instance and is encrypted at rest with an AWS Key Management Service (AWS KMS) key that has an alias of production-rds-key.
What must the CloudOps engineer do to meet these requirements with the LEAST administrative overhead?

A. Create an RDS read replica in the migration account. Replicate the KMS key.
B. Take a snapshot and create a new KMS key in the migration account with the same alias.
C. Take a snapshot of the RDS DB instance. Update the KMS key policy to allow access for the migration account root user. Share the snapshot with the migration account.
D. Export the database to Amazon S3 and import it into a new RDS instance.

正解：C

解説：
For encrypted RDS snapshots, cross-account sharing requires both sharing the snapshot and granting access to the KMS key used to encrypt it. By updating the KMS key policy to allow the migration account access, the encrypted snapshot can be restored in the migration account.
Option A uses native RDS snapshot sharing and minimal configuration changes, making it the least administrative overhead approach.
Options B, C, and D introduce unnecessary complexity, higher operational cost, or unsupported workflows.
