Oracle Cloud Infrastructure Developer Professional Sample Questions (Q146-Q151):

NEW QUESTION # 146
Your cloud-native banking microservice retrieves API tokens stored in OCI Vault. To meet strict security compliance standards, you must configure secret rules on these vault secrets. The security policies mandate that the secret contents must automatically expire and have their retrieval blocked 30 days after creation, and any previously used token content must never be allowed for reuse, even if the older secret version containing that content has been deleted. Which TWO configurations must you specify within the secret rules to satisfy these compliance requirements?

A. Set up a SECRET_REUSE_RULE with is_enforced_on_deleted_secret_versions set to false.
B. Set up a SECRET_REUSE_RULE with is_enforced_on_deleted_secret_versions set to true.
C. Set up a SECRET_EXPIRY_RULE with secret_version_expiry_interval set to " P30D " and is_secret_content_retrieval_blocked_on_expiry set to true.
D. Set up an HSM_PURGE_RULE that automatically runs a background execution task to permanently erase deleted secrets from the vault hardware.
E. Set up a SECRET_EXPIRY_RULE with secret_version_expiry_interval set to " P30D " and is_secret_content_retrieval_blocked_on_expiry set to false.

Answer: B,C

Explanation:
OCI Vault provides both Secret Expiry Rules and Secret Reuse Rules. secret_version_expiry_interval uses an ISO 8601 duration, so P30D establishes a 30-day validity period. Setting is_secret_content_retrieval_blocked_on_expiry to true ensures secret contents cannot be retrieved after expiry, satisfying the first requirement. For the second requirement, a SECRET_REUSE_RULE prevents previously used secret contents from being reused across versions. Oracle ' s SDK documentation confirms that is_enforced_on_deleted_secret_versions=true extends that restriction even when the previous secret version has been deleted. Setting either Boolean to false would weaken the stated controls.
HSM_PURGE_RULE is not one of the documented OCI Vault secret-rule types. Therefore, C and D jointly satisfy both requirements.

NEW QUESTION # 147
A service you are deploying to Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) uses a docker image from a private repository in OCI Registry (OCIR). Which configuration is necessary to provide access to this repository from OKE?

A. Create a docker-registry secret for OCIR with identity Auth Token on the cluster, and specify the imagePullSecret property in the application deployment manifest.
B. Create a docker-registry secret for OCIR with API key credentials on the cluster, and specify the imagePullSecret property in the application deployment manifest.
C. Create a dynamic group for nodes in the cluster, and a policy that allows the dynamic group to read repositories in the same compartment.
D. Add a generic secret on the cluster containing your identity credentials. Then specify a registryCredentials property in the deployment manifest.

Answer: A

NEW QUESTION # 148
Your company has recently deployed a new web application that uses Oracle Functions. Your manager instructs you to implement monitoring metrics to manage your systems more effectively. You know that Oracle Functions automatically monitors functions on your behalf and reports metrics via Oracle Cloud Infrastructure (OCI) Monitoring. Which TWO metrics are collected and made available by this feature?
(Choose two.)

A. Length of time a function runs
B. Amount of CPU used by a function
C. Number of times a function is invoked
D. Number of times a function Is removed
E. Amount of RAM used by a function

Answer: B,E

Explanation:
The correct answers are: Amount of RAM used by a function: Oracle Functions collects and reports the amount of memory (RAM) used by a function during its execution. This metric helps in monitoring and optimizing the resource consumption of functions. Length of time a function runs: Oracle Functions captures and provides the duration of function executions. This metric allows you to track the performance and responsiveness of your functions and identify any potential bottlenecks or delays. These metrics provide valuable insights into the resource utilization and performance of your functions, enabling you to monitor and optimize their behavior in the Oracle Cloud Infrastructure (OCI) environment.

NEW QUESTION # 149
Which of the following is NOT a criterion that is usually met by a microservice?

A. Highly maintainable
B. Organized around business capabilities.
C. Independently deployable
D. Tightly coupled

Answer: D

Explanation:
The correct answer is: " Tightly coupled. " Tightly coupling is not a criterion that is usually met by a microservice. In fact, microservices are designed to be loosely coupled. Loosely coupling refers to reducing dependencies and minimizing the direct interactions between different components or services. Microservices promote independence and autonomy, allowing each service to operate independently without being tightly bound to other services. The other options listed are criteria that are typically met by microservices:
Organized around business capabilities: Microservices architecture suggests designing services around specific business capabilities or functionalities. This allows for focused and specialized services that align with the organization ' s business needs. Independently deployable: Microservices are designed to be independently deployable units. Each microservice can be developed, tested, and deployed separately, without impacting other services. This enables agility and scalability in the deployment process. Highly maintainable:
Microservices are often designed to be highly maintainable. They are smaller in scope and focused on specific tasks, making it easier to manage and maintain individual services. Additionally, microservices can be updated, patched, or replaced without affecting the entire system, facilitating easier maintenance and evolution of the application. Therefore, the criterion that is NOT typically met by a microservice is being tightly coupled.

NEW QUESTION # 150
You are using Oracle Cloud Infrastructure (OCI) Resource Manager to manage your infrastructure lifecycle and wish to receive an email each time a Terraform action begins. How should you use the OCI Events service to do this without writing any code?

A. Create an OCI Notifications topic and email subscription with the destination email address. Then create an OCI Events rule matching " Resource Manager Stack - Update " condition, and select the notification topic for the corresponding action.
B. Create an OCI Notification topic and email subscription with the destination email address. Then create an OCI Events rule matching " Resource Manager Job - Create " condition, and select the notification topic for the corresponding action.
C. Create an OCI Email Delivery configuration with the destination email address. Then create an OCI Events rule matching " Resource Manager Job - Create " condition, and select the email configuration for the corresponding action.
D. Create a rule in OCI Events service matching the " Resource Manager Stack - Update " condition. Then select " Action Type: Email " and provide the destination email address.

Answer: B

Explanation:
The correct approach to receive an email each time a Terraform action begins in Oracle Cloud Infrastructure (OCI) Resource Manager without writing any code is as follows: Create an OCI Notification topic and email subscription with the destination email address. This will define the email delivery configuration. Create an OCI Events rule that matches the " Resource Manager Job - Create " condition. This rule will be triggered when a Resource Manager job is created. In the OCI Events rule, select the notification topic that was created in step 1 as the action for the corresponding event. This will ensure that the notification is sent to the specified email address. By following these steps, you can configure the OCI Events service to send an email notification whenever a Resource Manager job is created in OCI Resource Manager.
