                                    Oracle Cloud Infrastructure Developer Professional 1z0-1084-26 Prüfungsfragen mit Lösungen (Q131-Q136):

                                    131. Frage
                                    You have built a custom container image for your microservice and successfully pushed it to Oracle Cloud Infrastructure Registry (OCIR). Which OCI CLI command should you run to cryptographically sign the pushed image using a master encryption key managed in OCI Vault and upload the resulting signature?

                                    Antwort: A

                                    Begründung:
                                    Oracle explicitly documents oci artifacts container image-signature sign-upload for signing a Container Registry image and uploading its image signature. The operation requires the image OCID, compartment OCID, Vault master encryption key OCID, key-version OCID, and an approved RSA signing algorithm such as SHA_256_RSA_PKCS_PSS. Container Registry image-management commands are organized under the OCI CLI artifacts container command group, which is why the other command paths are invalid. container- engine relates to OKE rather than image-signature creation, and there is no container-registry image-signature top-level CLI group. Oracle ' s Container Registry documentation provides the exact command shown in option B for signing an already-pushed image using a key stored in OCI Vault.


                                    132. Frage
                                    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?

                                    Antwort: B

                                    Begründung:
                                    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.


                                    133. Frage
                                    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?

                                    Antwort: D

                                    Begründung:
                                    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.


                                    134. Frage
                                    Which of these is NOT a valid authentication method for accessing an OCI API Gateway deployment?

                                    Antwort: D

                                    Begründung:
                                    OCI API Gateway supports the following authentication methods for accessing an API deployment3:
                                    * HTTP Basic: The client sends a username and password with each request. The credentials are validated against a user database in Oracle Identity Cloud Service (IDCS).
                                    * API Key: The client sends an API key with each request. The API key is validated against a list of keys stored in IDCS or OCI Vault.
                                    * OAuth: The client obtains an access token from an authorization server (such as IDCS) and sends it with each request. The access token is validated against the authorization server and optionally checked for required scopes.
                                    * JWT Token: The client obtains a JSON Web Token (JWT) from an identity provider (such as IDCS or OCI IAM) and sends it with each request. The JWT is validated against the identity provider's public key and optionally checked for required claims. SAML Token is not a valid authentication method for accessing an OCI API Gateway deployment. SAML is an XML-based standard for exchanging authentication and authorization data between different parties, such as a service provider and an identity provider4. SAML tokens are typically used for web browser single sign-on (SSO) scenarios, not for API access4.


                                    135. Frage
                                    What is the open source engine for Oracle Functions?

                                    Antwort: D

                                    Begründung:
                                    The Fn Project is an open source serverless computing platform that serves as the engine for Oracle Functions. It provides a runtime environment for executing functions in a serverless architecture. The Fn Project enables developers to build and deploy functions using different programming languages, including Java, Python, Node.js, and more. The Fn Project is designed to be flexible and extensible, allowing developers to define functions as small units of code and execute them in response to events or triggers. It supports event- driven execution, allowing functions to be triggered by various events such as HTTP requests, messages from messaging systems, or changes in data. Oracle Functions leverages the Fn Project as its underlying engine, providing a managed serverless platform within the Oracle Cloud Infrastructure. It allows developers to easily develop, deploy, and manage functions using the familiar Fn Project framework and tooling. With Oracle Functions, developers can focus on writing their function code while leaving the infrastructure management, scaling, and operational tasks to the platform.
