Oracle Cloud Infrastructure Developer Professional Sample Questions (Q15-Q20):

NEW QUESTION # 15
Which protocol or mechanism does the Docker client use by default to communicate with the Docker daemon when both are running on the same local host?

A. Local UNIX Sockets
B. Secure Shell Sessions
C. Remote Procedure Calls
D. TCP Network Sockets

Answer: A

Explanation:
In the Linux/Unix environment normally assumed for OCI container development, the Docker client communicates with the locally running Docker daemon through a UNIX domain socket. Docker ' s default endpoint on Linux is unix:///var/run/docker.sock. This allows local inter-process communication without requiring a TCP network connection. TCP can be configured when the client must communicate with a daemon through a network, while SSH can provide secure access to a remote Docker daemon. RPC is not the default Docker client transport. Therefore, for a Docker client and daemon running locally on a Linux-based OCI development host, Local UNIX Sockets is the correct answer. On Windows, Docker uses a named pipe by default, so the answer is specifically applicable to the Linux/Unix OCI context.

NEW QUESTION # 16
Having created a Container Engine for Kubernetes (OKE) cluster, you can use Oracle Cloud Infrastructure (OCI) Logging to view and search the logs of applications running on the worker node compute instances in the cluster. Which task is NOT required to collect and parse application logs? (Choose the best answer.)

A. Enable monitoring for all worker nodes in the cluster.
B. Create a dynamic group with a rule that includes all worker nodes In the cluster.
C. Configure a custom log in OCI Logging with the appropriate agent configuration.
D. Set the OCI Logging option to Enabled for the cluster.

Answer: A

Explanation:
The correct answer is: Enable monitoring for all worker nodes in the cluster. Enabling monitoring for all worker nodes in the cluster is not required to collect and parse application logs using Oracle Cloud Infrastructure (OCI) Logging. Monitoring is a separate feature that allows you to collect metrics and monitor the health and performance of the worker nodes. To collect and parse application logs, you need to perform the following tasks: Set the OCI Logging option to Enabled for the cluster: This enables the OCI Logging service for the cluster. Create a dynamic group with a rule that includes all worker nodes in the cluster: This helps in targeting the logs generated by the worker nodes. Configure a custom log in OCI Logging with the appropriate agent configuration: This involves specifying the log source, log path, and log format to parse and collect the application logs. By completing these tasks, you can collect and parse the application logs generated by the applications running on the worker node compute instances in the OKE cluster.

NEW QUESTION # 17
Your organization has mandated strict IAM policy isolation for microservices accessing an Oracle Cloud Infrastructure (OCI) Queue named payment-queue in a compartment named prod-payment-compartment. A producer microservice deployed on an OCI Compute instance needs to publish transaction messages into the queue, but corporate security dictates that this microservice must not have permission to view queue configurations, delete queues, or read/consume messages. You have created a dynamic group named payment- producer-dg that contains the Compute instance hosting the producer microservice.
Which IAM policy statement must you write to satisfy this security requirement with the least privilege?

A. Allow dynamic-group payment-producer-dg to manage queue-push in compartment prod-payment- compartment
B. Allow dynamic-group payment-producer-dg to use queue-push in compartment prod-payment- compartment
C. Allow dynamic-group payment-producer-dg to use queues in compartment prod-payment-compartment
D. Allow dynamic-group payment-producer-dg to use queue-pull in compartment prod-payment- compartment

Answer: B

NEW QUESTION # 18
From a DevOps process standpoint, it is a good practice to keep changes to an application under version control. Which of the following allows changes to a Docker image to be stored in a version control system?

A. Updating docker-compose.yml
B. Updating Dockerfile
C. Executing docker commit
D. Executing docker save

Answer: C

Explanation:
The option that allows changes to a Docker image to be stored in a version control system is: docker commit The docker commit command is used to create a new image from a container ' s changes. It takes a running container as input, captures the changes made to it, and creates a new image with those changes. This new image can then be tagged and pushed to a registry, or saved locally. By using docker commit, you can effectively capture the changes made to a container as a new image and store it in a version control system along with the Dockerfile and other project files. This allows for reproducibility and traceability of changes to the Docker image over time.

NEW QUESTION # 19
Your organization requires automatic rotation of third-party API keys stored as secrets in OCI Vault every 90 days. You have created a custom serverless OCI Function named rotate-api-keys that handles the API key generation and updates. You are now configuring the automatic rotation properties of the OCI Vault secret via the OCI API. Which configuration must you specify on the secret to automatically run this custom OCI Function at the required interval?

A. Define an IAM policy that allows the vault to execute the OCI Function, and configure an OCI Events rule to capture the " Secret Expired " event to invoke the function.
B. Define a metric alarm in the OCI Monitoring service that triggers an OCI Notification topic whenever the secret ' s age exceeds 90 days, which then invokes the OCI Function.
C. Set the rotation_config with is_scheduled_rotation_enabled to true, set the rotation_interval to " P90D "
, and specify target_system_details with target_system_type set to " FUNCTION " and the function_id of your custom function.
D. Associate a Secret Rule of type SecretExpiryRule on the secret, and configure the rule configuration to trigger your OCI Function ' s API endpoint dynamically every 90 days.

Answer: C

Explanation:
OCI Vault natively supports scheduled secret rotation and integration with OCI Functions. The RotationConfig model contains is_scheduled_rotation_enabled, rotation_interval, and target_system_details.
Oracle specifies that enabling scheduled rotation requires a rotation interval represented using ISO 8601 duration syntax, so P90D expresses 90 days. For Function-based rotation, the target system is configured as a Function and the target details identify the Function OCID. Oracle further states that Secret Service invokes the configured rotation function as part of the rotation process. A SecretExpiryRule controls expiration rather than scheduled function-based rotation, while Monitoring alarms and Events rules would introduce separate orchestration rather than use Vault ' s native feature. Therefore, A correctly configures automatic 90-day Function-based rotation.
