NEW QUESTION # 148
You are creating an API deployment in Oracle Cloud Infrastructure (OCI) API Gateway and you want to configure request policies to control access. Which is NOT available in OCI API Gateway?
Answer: D
Explanation:
The correct answer is: Controlling access to the backend OCI resources. OCI API Gateway does not provide direct control over access to backend OCI resources. It primarily focuses on managing and securing access to APIs exposed through the gateway. The gateway acts as a front-end for APIs and provides features such as authentication, authorization, rate limiting, and CORS support. While you can configure authentication and authorization policies, limit the number of requests, and enable CORS support in OCI API Gateway, it does not directly control access to backend OCI resources. Access to backend resources is typically managed through other means, such as IAM policies, network security rules, or resource-specific access controls.
NEW QUESTION # 149
Which configuration parameter defines the duration a message remains inside an Oracle Cloud Infrastructure (OCI) Queue before being automatically deleted by the service if it is not consumed?
Answer: C
Explanation:
Themaximum retention perioddefines the total amount of time OCI Queue retains a message before automatically deleting it if a consumer has not removed it. Oracle currently allows this value to be configured from 10 seconds through seven days, with a default of one day. Visibility timeout serves a different purpose:
after a consumer retrieves a message, it temporarily hides that message from other consumers. Maximum delivery attempts controls how many unsuccessful delivery cycles can occur before a message is moved to the dead letter queue. Polling timeout determines how long a consumer request waits for messages to become available. Therefore, only the maximum retention period controls the overall lifetime of an unremoved message in OCI Queue.

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?
Answer: C
NEW QUESTION # 151
You have been asked to update an OKE cluster to a network configuration that has the least attack surface while the deployed applications are still directly available for access from the Internet. Which is a valid OKE cluster network configuration that meets this requirement? (Choose the best answer.)
Answer: B
Explanation:
The valid OKE cluster network configuration that meets the requirement of having the least attack surface while still allowing direct access to the deployed applications from the Internet is: Private subnets for nodes and the Kubernetes API endpoint; public subnets for load balancers. By placing the nodes and the Kubernetes API endpoint in private subnets, they are not directly accessible from the Internet, reducing the attack surface.
The load balancers, on the other hand, are placed in public subnets, allowing them to be accessed from the Internet and serve as the entry point for accessing the deployed applications. This configuration ensures that the critical components of the cluster, such as the nodes and the API endpoint, are protected within the private network, while still providing accessibility to the applications through the load balancers. It helps to enhance security by limiting direct access to the internal components of the cluster while maintaining the availability of the deployed applications.
NEW QUESTION # 152
You plan to implement logging in your services that will run in Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). Which statement describes the appropriate logging approach?
Answer: B
Explanation:
The appropriate logging approach for services running in Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) is: " All services log to standard output only. " When running services in a containerized environment like OKE, it is recommended to follow the Twelve-Factor App methodology, which suggests treating logs as event streams. According to this methodology, services should write their log events to standard output (stdout) instead of writing to log files. By logging to standard output, the container runtime (such as Kubernetes) can collect and aggregate the logs generated by the services. These logs can then be accessed and managed through the container runtime ' s logging infrastructure. Logging to standard output offers several advantages in a containerized environment: Simplicity and consistency: Standardizing on logging to stdout ensures a consistent approach across different services, making it easier to manage and analyze logs. Log aggregation: The container runtime can collect the logs from all the running containers and provide centralized log management, allowing you to access and search logs from different services in one place. Scalability: Since logs are written to stdout, they can be easily handled by the container runtime ' s log management system, which can scale to handle large volumes of log data. Separation of concerns: By logging to stdout, the responsibility of managing log files and their rotation is shifted to the container runtime, allowing the services to focus on their core functionality. While it is possible to log to log files or external logging systems, the recommended approach in a containerized environment like OKE is to log to standard output and leverage the logging infrastructure provided by the container runtime.
