Amazon AWS Certified DevOps Engineer - Professional 認定 DOP-C02 試験問題 (Q421-Q426):

質問 # 421
A company is using AWS CodePipeline to deploy an application. According to a new guideline, a member of the company's security team must sign off on any application changes before the changes are deployed into production. The approval must be recorded and retained.
Which combination of actions will meet these requirements? (Select TWO.)

正解：A、E

解説：
To meet the new guideline for application deployment, the company can use a combination of AWS CodePipeline and AWS CloudTrail. A manual approval action in CodePipeline allows the security team to review and approve changes before they are deployed. This action can be configured to pause the pipeline until approval is granted, ensuring that no changes move to production without the necessary sign-off. Additionally, by creating an AWS CloudTrail trail, all actions taken within CodePipeline, including approvals, are recorded and delivered to an Amazon S3 bucket. This provides an audit trail that can be retained for compliance and review purposes.
:
AWS CodePipeline's manual approval action provides a way to ensure that a member of the security team can review and approve changes before they are deployed1.
AWS CloudTrail integration with CodePipeline allows for the recording and retention of all pipeline actions, including approvals, which can be stored in Amazon S3 for record-keeping2.


質問 # 422
A company deploys an application to Amazon EC2 instances. The application runs Amazon Linux 2 and uses AWS CodeDeploy. The application has the following file structure for its code repository:
appspec.yml
config/config.txt application/web
The appspec yml file has the following contents in the files section
files:
- source: config/config.txt
destination: /usr/local/src/config.txt
- source: /
destination: /var/www/html
The appspec.yml file has the following contents in the files section:
What will the result be for the deployment of the config.txt file?

正解：B

解説：
Deployment of config.txt file based on the appspec.yml:
The appspec.yml file specifies that config/config.txt should be copied to /usr/local/src/config.txt.
The source: / directive in the appspec.yml indicates that the entire directory structure starting from the root of the application source should be copied to the specified destination, which is /var/www/html.
Result of the Deployment:
The config.txt file will be specifically deployed to /usr/local/src/config.txt as per the explicit file mapping.
The entire directory structure including application/web will be copied to /var/www/html, but this does not include config/config.txt since it has a specific destination defined.
Thus, the config.txt file will be deployed only to /usr/local/src/config.txt.
Therefore, the correct answer is:
C). The config.txt file will be deployed to only /usr/local/src/config.txt.

質問 # 423
A DevOps engineer needs to design a cloud-based solution to standardize deployment artifacts for AWS Cloud deployments and on-premises deployments. There is currently no routing traffic between the on- premises data center and the AWS environment.
The solution must be able to consume downstream packages from public repositories and must be highly available. Data must be encrypted in transit and at rest. The solution must store the deployment artifacts in object storage and deploy the deployment artifacts into Amazon Elastic Container Service (Amazon ECS).
The deployment artifacts must be encrypted in transit if the deployment artifacts travel across the public internet.
The DevOps engineer needs to deploy this solution in less than two weeks.
Which solution will meet these requirements?

正解：B

解説：
Comprehensive and Detailed Explanation From Exact Extract:
AWS CodeArtifact is a fully managed artifact repository service that supports popular package formats and can proxy downstream public repositories securely. It integrates seamlessly with both AWS Cloud and on- premises environments and stores artifacts in highly durable object storage (Amazon S3). CodeArtifact encrypts data at rest and in transit by default.
Because there is currently no routing between the on-premises data center and AWS, establishing a third-party software VPN appliance for connectivity provides secure communication without requiring complex AWS Direct Connect or multiple VPN setups.
This solution can be deployed quickly (within two weeks), is highly available, and meets encryption requirements. Using CodeArtifact eliminates the need to maintain third-party artifact servers, reducing operational overhead and improving reliability.
Options B, C, and D introduce higher complexity with AWS Direct Connect or multiple VPN connections and third-party software that increases deployment time and operational burden, which is against the requirement for rapid deployment and high operational efficiency.
Reference from AWS Official Documentation:
* AWS CodeArtifact Overview:"CodeArtifact is a fully managed artifact repository service that makes it easy for organizations to securely store, publish, and share software packages used in their software development process."(AWS CodeArtifact Documentation)
* Encryption in AWS CodeArtifact:"CodeArtifact encrypts data at rest and in transit by default."(AWS CodeArtifact Security)
* VPN Appliance Deployment:"Software VPN appliances are commonly used for secure, encrypted connectivity between on-premises data centers and AWS."(AWS VPN Options)

質問 # 425
A company has an organization in AWS Organizations for its multi-account environment. A DevOps engineer is developing an AWS CodeArtifact based strategy for application package management across the organization. Each application team at the company has its own account in the organization. Each application team also has limited access to a centralized shared services account.
Each application team needs full access to download, publish, and grant access to its own packages. Some common library packages that the application teams use must also be shared with the entire organization.
Which combination of steps will meet these requirements with the LEAST administrative overhead? (Select THREE.)

正解：A、B、C

解説：
* Step 1: Creating a Centralized Domain in the Shared Services Account
To manage application package dependencies across multiple accounts, the most efficient solution is to create a centralized domain in the shared services account. This allows all application teams to access and manage package repositories within the same domain, ensuring consistency and centralization.
Action: Create a domain in the shared services account.
Why: A single, centralized domain reduces the need for redundant management in each application team's account.
Reference:
This corresponds to Option B: Create a domain in the shared services account. Grant the organization read access and CreateRepository access.
* Step 2: Sharing Repositories Across Teams with Upstream ConfigurationsTo share common library packages across the organization, each application team's repository can point to the shared services repository as an upstream repository. This enables teams to access shared packages without managing them individually in each team's account.
Action: Create a repository in the shared services account and set it as the upstream repository for each application team.
Why: Upstream repositories allow package sharing while maintaining individual team repositories for managing their own packages.
This corresponds to Option D: Create a repository in the shared services account. Grant the organization read access to the repository in the shared services account. Set the repository as the upstream repository in each application team's repository.
* Step 3: Using Resource-Based Policies for Cross-Account AccessFor teams that need to share their packages with other application teams, resource-based policies can be applied to grant the necessary permissions. These policies allow cross-account access without having to manage permissions at the individual account level.
Action: Create resource-based policies that allow read access to the repositories across application teams.
Why: This simplifies management by centralizing permissions in the shared services account while allowing cross-team collaboration.
This corresponds to Option E: For teams that require shared packages, create resource-based policies that allow read access to the repository from other application teams' accounts.
