NEW QUESTION # 94
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: A
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 # 95
Which container network interface plugin must be selected when creating an Oracle Cloud Infrastructure Container Engine for Kubernetes cluster that requires pod IP addresses to be directly routable from peered virtual cloud networks and on-premises environments?
Answer: C
Explanation:
The OCI VCN-Native Pod Networking CNI plugin assigns pod IP addresses directly from the OCI VCN address space instead of allocating addresses from a separate overlay network. Oracle specifically states that these pod IP addresses are directly routable from other VCNs connected through VCN peering and from on- premises networks. This architecture makes pods first-class participants in OCI networking and enables native VCN functionality such as network security groups, security lists, and VCN flow logs to be applied to pod traffic. Flannel uses an overlay model and therefore does not provide the required directly routable VCN pod addresses. Calico is commonly associated with Kubernetes NetworkPolicy enforcement rather than being the required OCI native routing CNI. Therefore, D is correct.
NEW QUESTION # 96
As a developer, you have been tasked with implementing a microservices-based application. Which THREE technologies are best suited to accomplish the task? (Choose three.)
Answer: A,E,F
Explanation:
The three technologies best suited for implementing a microservices-based application are: Service Mesh: A service mesh is a dedicated infrastructure layer that provides features like service discovery, load balancing, encryption, authentication, and observability for microservices. It helps in managing the communication and interactions between microservices in a scalable and secure manner. Kubernetes: Kubernetes is an open- source container orchestration platform that enables the deployment, scaling, and management of containerized applications. It provides features like automated scaling, service discovery, load balancing, and self-healing capabilities, which are essential for managing microservices in a distributed environment.
Docker: Docker is a popular containerization platform that allows packaging applications and their dependencies into lightweight containers. It provides a consistent and portable environment for running microservices, enabling easy deployment and scalability. Docker also facilitates isolation and resource efficiency, making it an ideal choice for deploying microservices. While Big Data, Anomaly Detection, and Terraform are valuable technologies, they are not specifically focused on enabling the implementation of microservices-based applications.
NEW QUESTION # 97
You encounter an unexpected error when invoking Oracle Functions from your Cloud Shell session named myfunction in the myapp application. Which option will get you more information on the error?
Answer: D
Explanation:
The option that will get you more information on the error when invoking Oracle Functions from your Cloud Shell session is: " DEBUG=1 fn invoke myapp myfunction " . Setting the environment variable DEBUG=1 before invoking the function using the fn command allows you to enable debug mode, which provides more detailed information about the execution of the function. This can be useful for troubleshooting and understanding the root cause of the error. By using the command " DEBUG=1 fn invoke myapp myfunction "
, the function invocation will be executed with debug mode enabled, and additional debug information will be displayed in the console output. This information can include stack traces, detailed error messages, and other relevant details that can help identify and resolve the issue. Using the verbose option (--verbose) or debug option (--debug) with the fn command may also provide additional information, but the specific behavior may depend on the version and configuration of the fn CLI tool. While contacting Oracle support with the error message is always an option, enabling debug mode using the DEBUG=1 environment variable provides immediate access to more detailed information and can help in diagnosing and resolving the error more efficiently.
NEW QUESTION # 98
Which " Action Type " option is NOT available in an Oracle Cloud Infrastructure (OCI) Events rule definition?
Answer: D
Explanation:
An action is a response that you define for the rule to perform when the filter finds a matching event1. The action type specifies the service that you want to invoke by delivering the event message1. The following action types are available in OCI Events rule definition1:
* Streaming: Send to a stream from Oracle Streaming Service.
* Notifications: Send to an Oracle Notification Service topic.
* Functions: Send to an Oracle Functions Service endpoint. Email is not a valid action type for OCI Events rule definition. To send an email as an action, you need to use the Notifications service and subscribe to a topic with an email protocol2.
