NEW QUESTION # 100
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?
Answer: A
Explanation:
OCI Queue exposes separate IAM resource types specifically to enforce producer/consumer separation.
Oracle documents queue-push for producers and queue-pull for consumers. The policy Allow dynamic-group payment-producer-dg to use queue-push in compartment prod-payment-compartment grants only QUEUE_PRODUCE, which covers the PutMessages API operation. It does not grant GetMessages, DeleteMessage, queue configuration reads, or queue administration. By comparison, use queues is broader because the general queues resource type includes read, update, produce, and consume capabilities. queue- pull provides consumer permissions rather than producer permissions, and manage queue-push is not the correct permission model for this specialized resource type. Therefore, A precisely implements least-privilege publishing for the producer microservice.
NEW QUESTION # 101
Which statement is NOT valid regarding context variables used for dynamic backend routing in Oracle Cloud Infrastructure API Gateway?
Answer: D
Explanation:
Oracle API Gateway documents the context-variable selectors available for dynamic backend routing.
Supported selectors include request.auth[ < key > ], request.headers[ < key > ], request.host, request.path[ < key > ], request.query[ < key > ], request.subdomain[ < key > ], and usage-plan information. Therefore, headers, authentication claims, and query parameters can all participate directly in backend-selection rules.
Although API Gateway can expose the request body to amulti-argument authorizer function, Oracle does not list request.body[ < key > ] as a supported selector for dynamic backend routing. Its presence in that separate authorizer context does not make it a dynamic-routing selector capable of parsing arbitrary JSON fields.
Consequently, A, B, and C describe supported routing context variables, while D incorrectly extends the routing model to request-body key selection.
NEW QUESTION # 102
You are building a container image and pushing it to Oracle Cloud Infrastructure Registry (OCIR). You need to ensure that these images never get deleted from the repository. Which action should you take?
Answer: A
Explanation:
To prevent images from being deleted from a repository, you can set the global policy of image retention to
"Retain All Images". This policy applies to all repositories in the tenancy and overrides any individual repository settings. You can also lock the policy to prevent any changes to it.Verified References: Using Retention Rules to Preserve Data
NEW QUESTION # 103
Your development team wants to configure API Gateway request validation to shield an upstream backend microservice from ill-formed API calls. You want to test the validation rules in your staging environment first without blocking any non-compliant client requests, and you want to ensure the gateway checks that a mandatory HTTP header is present. Which TWO configurations should you apply to your API Gateway deployment specification to meet this requirement?
Answer: A,B
Explanation:
OCI API Gateway request validation supportsEnforcing, Permissive, and Disabledvalidation modes. In Permissive mode, requests are validated and failures are recorded, but even non-compliant requests continue to the backend, making it appropriate for testing the impact of validation before enforcing it. Oracle also supports explicit header validation rules in which a header can be marked required: true. Enforcing mode instead blocks requests that fail validation and returns a 4xx response. No dynamic group is required for API Gateway to validate standard HTTP headers, and request.auth relates to authentication context rather than header-presence validation. Therefore, A and C directly satisfy both stated requirements.
NEW QUESTION # 104
(CHK_1 > 3) You have an e-commerce application that loads customers ' transactional data into the Oracle Cloud Infrastructure (OCI) Streaming service. The data must now be extracted and transformed before sending it to a third-party REST endpoint. You have been directed to leverage the OCI Service Connector Hub to automate this process. Which configuration option would address this requirement?
Answer: C
Explanation:
To address the requirement of extracting and transforming data from the Oracle Cloud Infrastructure (OCI) Streaming service and sending it to a third-party REST endpoint using the OCI Service Connector Hub, the best configuration option is: Configure a new service connector as follows: * Source: Streaming * Task: None
* Target: Notifications By selecting the Streaming service as the source, you can capture the transactional data from the stream. Since there is a need to transform and send the data to a third-party REST endpoint, you don
' t need to specify any specific task in the connector. The target is set to Notifications, which allows you to send the transformed data to an endpoint outside of the OCI environment. Notifications can be configured to deliver the data to various supported destinations, including HTTP endpoints, email addresses, and more. This configuration enables you to automate the process of extracting data from the streaming service and sending it to the desired third-party REST endpoint, fulfilling the requirement of extracting, transforming, and forwarding the data.
