NEW QUESTION # 125
You are configuring a deployment script running in an OCI Compute Instance that needs to retrieve database credentials stored in OCI Vault. Which OCI CLI command should your script execute to retrieve the secret bundle containing the credentials?
Answer: B
Explanation:
Oracle separates secret-management operations from retrieval of secret contents. The current OCI CLI command for retrieving a secret bundle is oci secrets secret-bundle get --secret-id < secret_id > . If no specific version, stage, or version name is supplied, Oracle returns the bundle associated with the secret version marked CURRENT. The secrets data-plane command retrieves the actual secret bundle, including its encoded content and version properties. The alternative command paths shown in A, C, and D do not represent the documented OCI CLI operation for obtaining secret contents. Oracle ' s current Secrets Management documentation provides the same command directly when describing how applications and administrators retrieve a secret ' s contents. Therefore, option B is the exact verified command.

A developer using Oracle Cloud Infrastructure (OCI) API Gateway needs to authenticate the API requests to their web application. The authentication process must be implemented using a custom scheme which accepts string-based parameters from the API caller. Which approach should the developer use in this scenario?
Answer: C
Explanation:
In the given scenario, the developer should use the approach of creating an authorizer function using token- based authorization. Token-based authorization is a commonly used approach for authenticating API requests.
It involves generating and issuing tokens to API callers, which they can then include in the requests they make to the API. The tokens serve as proof of authentication and are validated by the server to ensure the caller ' s identity and access rights. By creating an authorizer function using token-based authorization, the developer can implement a custom scheme that accepts string-based parameters from the API caller. This allows the developer to define their own authentication logic and validate the provided tokens according to their requirements. The authorizer function can be configured in the OCI API Gateway to be invoked before forwarding the request to the web application. It will perform the necessary token validation and authentication checks, allowing only authorized requests to access the protected resources of the web application.

Which of the following step is NOT required for setting up the Container Engine for Kubernetes (OKE) cluster access using a local installation of kubectl?
Answer: D
Explanation:
The step that is NOT required for setting up the Container Engine for Kubernetes (OKE) cluster access using a local installation of kubectl is to generate an Auth token from the OCI console. The authentication for accessing the OKE cluster using kubectl can be performed using the OCI CLI configuration, specifically the API signing key pair and the kubeconfig file. Here are the correct steps for setting up the OKE cluster access using a local installation of kubectl: Set up the kubeconfig file: The kubeconfig file contains the necessary information to authenticate and access the OKE cluster using kubectl. It includes details such as the cluster endpoint, authentication method, and credentials. Generate an API signing key pair (if you do not already have one) and upload the public key of the API signing key pair: The API signing key pair is used for authentication with the OCI services. The public key of the key pair needs to be uploaded to the OCI Console to associate it with your user account. Install and configure the Oracle Cloud Infrastructure (OCI) CLI: The OCI CLI provides a command-line interface to interact with the OCI services. It needs to be installed and configured with your OCI credentials, including the user ' s OCID, tenancy OCID, region, and the path to the API signing key pair. By completing these steps, you can configure kubectl to access and manage your OKE clusters from your local machine using the OCI CLI authentication configuration.
NEW QUESTION # 128
As a Cloud Native developer, you have written a web service for your company. However, your security team has suggested that your web service should address Distributed Denial-of-Service (DDoS) attack. You are time-constrained and you need to ensure that this is implemented as soon as possible. What should you do in this scenario? (Choose the best answer.)
Answer: B
Explanation:
The correct answer in this scenario is to use the OCI API Gateway service and configure rate limiting. Using the OCI API Gateway service and configuring rate limiting is an effective approach to address Distributed Denial-of-Service (DDoS) attacks. By implementing rate limiting, you can control the number of requests that can be made to your web service within a specific time frame. This helps to prevent overload and ensures that your service can handle legitimate traffic while mitigating the impact of DDoS attacks. By leveraging the OCI API Gateway service, you can easily configure rate limiting rules to restrict the number of requests per second or per minute. This allows you to set appropriate thresholds and safeguard your web service from being overwhelmed by excessive requests. The API Gateway acts as a protective layer, filtering out malicious traffic and ensuring the smooth operation of your service. While options like OCI Virtual Cloud Network (VCN) segregation and third-party service integrations may contribute to overall security, they do not specifically address DDoS attacks as efficiently as rate limiting. VCN segregation focuses more on network segmentation and isolation, while third-party service integration may introduce additional dependencies and complexities.
Re-writing your web service and implementing rate limiting is a viable option, but it may not be feasible considering the time constraints mentioned. Leveraging the OCI API Gateway service provides a quicker and easier solution to implement DDoS attack mitigation through rate limiting.
NEW QUESTION # 129
Your organization has deployed a custom OCI Authorizer Function in a compartment named secure-auth- compartment to perform token-based validation for all ingress traffic. You have set up an API Gateway in a compartment named public-gateway-compartment with an associated dynamic group named apigw-dg containing the gateway instance. The API Gateway deployment is currently returning HTTP 500 errors because the gateway lacks the necessary permissions to invoke the authorizer function during request validation. Which minimal IAM policy statement should you write to grant the API Gateway the required permission to successfully invoke the authorizer function?
Answer: D
Explanation:
Oracle ' s documented API Gateway-to-Functions integration uses a dynamic group representing the API Gateway and an IAM policy granting that dynamic group use functions-family in the compartment containing the target Function. The use verb provides the operational permission necessary for invocation without granting unnecessary administrative control. manage functions-family would be excessively privileged because it includes lifecycle management capabilities. The read and inspect verbs are insufficient for executing a Function and, in options C and D, are also scoped to the wrong compartment. Because the authorizer resides in secure-auth-compartment, authorization must apply there. Consequently, A implements the Oracle-documented pattern and satisfies least privilege for API Gateway invocation of the custom authorizer Function.
