Oracle Updated 1z0-1084-26 Exam Questions and Answers by zian

Oracle explicitly states that youcannot create a container image target using a repository that is already specified in another target. Therefore, a single OCIR repository cannot simultaneously be assigned to multiple Vulnerability Scanning targets simply to apply different recipes, making A invalid. Oracle also documents that a newly created target scans a configurable initial number of existing images, with one image being the default, and subsequently scans newly pushed images. Scan results are stored in the compartment containing the Vulnerability Scanning target, even when the repository resides elsewhere. Before creating a target, administrators must also grant Vulnerability Scanning permission to pull images from Container Registry. Consequently, B, C, and D accurately describe documented VSS behavior.

Explanation

To mandate image verification when deploying container images to Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) clusters, you should enable image verification policies separately for each OKE cluster. This is enforced at the cluster level. Enabling image verification policies at the cluster level ensures that all container images deployed to the OKE cluster are automatically verified against the specified master encryption key (MEK). This helps maintain the security and integrity of the deployed microservices by ensuring that only signed and trusted container images are used. Enabling image verification policies at the cluster level allows for consistent and centralized enforcement of the verification process across all nodes and node pools within the cluster. It provides a standardized approach to image verification for the entire cluster, simplifying management and ensuring compliance with the organization ' s mandate. Enabling image verification policies separately for each node pool or at the pod level would introduce complexity and potential inconsistencies in the verification process. Therefore, enforcing image verification at the cluster level is the recommended approach.

Oracle Streaming exposes separate IAM resource types for producers and consumers. Granting use stream-pull provides STREAM_CONSUME, covering operations such as GetMessages, CreateCursor, group cursors, heartbeats, and commits without granting STREAM_PRODUCE. Granting use streams would be broader because that resource type includes both production and consumption capabilities. Oracle Functions can be placed in a dynamic group with a rule using resource.type = ' fnfunc ' together with the Function ' s compartment OCID. compute would not match an Oracle Function resource, and stream-push provides the opposite permission by allowing message publication. Therefore, A establishes consume-only Streaming permission while C correctly associates the Functions resources with the dynamic group.

API mocking is a technique that simulates the behavior of real APIs without requiring the actual implementation or deployment of the dependent services1. API mocking allows you to test changes to service A without deploying all of its dependencies, such as service B, by creating mock responses for the APIs that service A relies on1. API mocking has several benefits, such as1:

Faster testing: You can test your service A without waiting for service B to be ready or available, which reduces the testing time and feedback loop.

Isolated testing: You can test your service A in isolation from service B, which eliminates the possibility of external factors affecting the test results or causing errors.

Controlled testing: You can test your service A with different scenarios and edge cases by creating mock responses that mimic various situations, such as success, failure, timeout, etc.
