질문 # 16
Which technique is used for testing the entire user flow as well as the moving parts of a cloud native app, ensuring that there are no high-level discrepancies?

A. Contract Testing
B. Integration Testing
C. Unit Testing
D. Component Testing
E. End-to-end Testing

정답：E

설명：
End-to-end testing is a technique that involves checking the entire user flow as well as the moving parts of a cloud native app, ensuring that there are no high-level discrepancies3. End-to-end testing simulates real user scenarios and validates the functionality, performance, reliability, and security of the app from start to finish3. End-to-end testing has several benefits, such as3:
Comprehensive testing: You can test your app as a whole and verify that all the components work together as expected.
User-centric testing: You can test your app from the user's perspective and ensure that it meets the user's needs and expectations.
Quality assurance: You can test your app in a realistic environment and identify any issues or defects before releasing it to the users.

질문 # 17
Your team has been tasked with debugging a Cloud Native application developed using the following Oracle Cloud Infrastructure (OCI) services: Object Storage, Events, Functions, API Gateway, and Autonomous Database. Which of these is NOT a valid option for troubleshooting issues in OCI? (Choose the best answer.)

A. View service metric information from the OCI Monitoring service.
B. Trace performance issues In the Application Performance Monitoring service by enabling Function traces.
C. Leverage OCI Cloud Guard to extract and visualize the debug logs generated by your application.
D. Configure the application to send logs to the OCI Logging service.
E. Use OCI Service Connector Hub to configure a service connector to automatically send logs to the OCI Logging Analytics service.

정답：B

설명：
To troubleshoot issues in OCI, the option that is not valid is: Trace performance issues in the Application Performance Monitoring service by enabling Function traces. While the Application Performance Monitoring service in OCI allows you to monitor and trace the performance of your applications, it is specifically designed for monitoring OCI Functions (serverless functions) and does not directly apply to all types of applications. The other options mentioned, such as configuring logs in the OCI Logging service, leveraging OCI Cloud Guard for debug logs, viewing service metrics in the OCI Monitoring service, and using OCI Service Connector Hub for log forwarding, are valid options for troubleshooting and monitoring applications in OCI.

질문 # 18
A developer using Oracle Cloud Infrastructure (OCI) API Gateway needs to authenticate the API requests to their web application. The authentication process must be implemented using a custom scheme which accepts string-based parameters from the API caller. Which approach should the developer use in this scenario?

A. Create an authorizer function using token-based authorization.
B. Create an authorizer function using request header authorization.
C. Create a cross account functions authorizer.
D. Create an authorizer function using OCI Identity and Access Management 91AM) based authentication.

정답：A

설명：
In the given scenario, the developer should use the approach of creating an authorizer function using token-based authorization. Token-based authorization is a commonly used approach for authenticating API requests. It involves generating and issuing tokens to API callers, which they can then include in the requests they make to the API. The tokens serve as proof of authentication and are validated by the server to ensure the caller's identity and access rights. By creating an authorizer function using token-based authorization, the developer can implement a custom scheme that accepts string-based parameters from the API caller. This allows the developer to define their own authentication logic and validate the provided tokens according to their requirements. The authorizer function can be configured in the OCI API Gateway to be invoked before forwarding the request to the web application. It will perform the necessary token validation and authentication checks, allowing only authorized requests to access the protected resources of the web application.

질문 # 19
Which is NOT a valid use case for leveraging the Oracle Cloud Infrastructure (OCI) Events service?

A. Publishing a notification when long-lived tasks complete, such as an OCI Autonomous Database backup completion.
B. Capturing the OCI Monitoring service alarms and invoking autoscaling of compute instances.
C. Publishing all the OCI resource events in a specific compartment to the OCI Streaming service for later analysis.
D. Triggering a notification action when a function completes its execution.
E. Triggering a function deployed in Oracle Functions when new files are uploaded to an OCI Object Storage bucket.

정답：B

설명：
The use case that is NOT a valid use case for leveraging the Oracle Cloud Infrastructure (OCI) Events service is "Capturing the OCI Monitoring service alarms and invoking autoscaling of compute instances." The OCI Events service is designed to provide event-driven architecture and enable automated responses to events occurring within the Oracle Cloud Infrastructure. It allows you to react to changes and activities happening within your OCI resources. The Events service can be used to trigger actions based on events like file uploads, resource changes, or task completions. However, capturing the OCI Monitoring service alarms and invoking autoscaling of compute instances is not a direct functionality provided by the OCI Events service. Autoscaling based on monitoring metrics is typically handled by the OCI Autoscaling service, which is specifically designed for that purpose. The OCI Monitoring service provides monitoring and alerting capabilities, while the Autoscaling service handles the dynamic scaling of compute instances based on predefined policies and thresholds.

질문 # 20
(CHK_4>2) You have a scenario where a DevOps team wants to store secrets in Oracle Cloud Infrastructure (OCI) Vault so that it can inject the secrets into an app's environment variables (for example, MYSQL_DB_PASSWD) at deployment time. Which is NOT valid about managing secrets in the OCI Vault service?

A. A secret reuse rule prevents the use of secret contents across different versions of a secret.
B. You can manually create new secrets as well as new secret versions using the OCI Console:
C. A unique OCID is automatically generated for each secret and remains unchanged even when creating a new secret version.
D. New secret versions automatically expire in 90 days unless you configure an expiry rule.

정답：C

설명：
The correct answer is: "A unique OCID is automatically generated for each secret and remains unchanged even when creating a new secret version." The statement that is NOT valid about managing secrets in the OCI Vault service is: "A unique OCID is automatically generated for each secret and remains unchanged even when creating a new secret version." In OCI Vault, a secret is identified by its OCID (Oracle Cloud Identifier), which is a unique identifier for each resource in Oracle Cloud Infrastructure. However, when a new secret version is created for an existing secret, the OCID remains the same for the secret itself, but a new OCID is generated for the secret version. This allows you to track and manage different versions of a secret while maintaining a consistent OCID for the secret itself. The other statements mentioned are valid: You can manually create new secrets as well as new secret versions using the OCI Console. This means you have control over creating and managing secrets within the Vault service. A secret reuse rule prevents the use of secret contents across different versions of a secret. This ensures that each secret version maintains its own unique set of contents and avoids accidental reuse or sharing of secrets across versions. By default, new secret versions automatically expire in 90 days unless you configure an expiry rule. This helps enforce good security practices by automatically rotating secrets periodically, reducing the risk of unauthorized access in case of compromise. Therefore, the statement that is NOT valid is the one regarding the uniqueness and consistency of the OCID when creating new secret versions.
