Oracle 1z0-1084-26 Exam Syllabus Topics:

Oracle Cloud Infrastructure Developer Professional Sample Questions:

Question 1

Your organization mandates that all containerized workloads deployed to Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) must utilize Kubernetes NetworkPolicy resources, such as Calico, to enforce strict micro-segmentation of traffic. You have deployed these workloads to an enhanced OKE cluster using virtual node pools to minimize infrastructure maintenance. During testing, you discover that the Calico installation fails because NetworkPolicy resources and third-party CNI policy integrations are completely unsupported on this specific node configuration. How should you resolve this security implementation challenge while continuing to use VCN-Native Pod Networking?

A. Upgrade your OKE virtual nodes to Kubernetes version 1.30 or higher, which enables native, agentless NetworkPolicy support on virtual nodes.
B. Define an OCI IAM policy that grants the OKE workload identity access to manage network security lists at the virtual node level.
C. Migrate your workloads to managed node pools within the OKE cluster, where VCN-Native Pod Networking supports Calico for NetworkPolicy enforcement.
D. Reconfigure your virtual node pools to use the Flannel overlay plugin, which natively implements network policy isolation on virtual nodes.

Question 2

Which statement is NOT valid regarding the configurations and behaviors of Oracle Cloud Infrastructure (OCI) Queue?

A. The visibility timeout of a message is configurable from 1 second to 12 hours at the queue level and can be extended by a consumer during processing.
B. The maximum retention period of a message is configurable from 10 seconds to 7 days and cannot be changed after the queue has been created.
C. The maximum number of delivery attempts before a message is transferred to a dead letter queue is configurable to values from 1 to 20.
D. The maximum payload size of a single message published to an Oracle Cloud Infrastructure (OCI) Queue can be configured up to 1 MB.

Question 3

You have a containerized application that requires access to an Autonomous Transaction Processing (ATP) Database. Which option is NOT valid when the container is deployed in an OKE cluster? (Choose the best answer.)

A. Install the Oracle Cloud Infrastructure Service Broker on the Kubernetes cluster and deploy ServiceInstance and ServiceBinding resources for ATP. Then use the specified binding name as a volume in the application deployment manifest.
B. Enable Oracle REST Data Services for the required schemas and connect via HTTPS.
C. Use Kubernetes secrets to configure environment variables on the container with ATP instance OCID, and OCI API credentials. Then use the CreateConnection API endpoint from the service runtime.
D. Create a Kubernetes secret with contents from the instance Wallet files. Use this secret to create a volume mounted to the appropriate path in the application deployment manifest.

Question 4

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?

A. Controlling access to the backend OCI resources.
B. Enabling Cross-Origin Resource Sharing (CORS) support.
C. Providing authentication and authorization.
D. Limiting the number of requests sent to the backend services.

Question 5

To enforce mutual TLS (mTLS) authentication for clients of your microservices, your team has chosen to leverage the Oracle Cloud Infrastructure (OCI) API Gateway service to create new API Deployments that will direct requests to your microservices. Which is NOT valid regarding the mTLS options in OCI API Gateway?

A. Adding a custom certificate authority (CA) or custom CA bundle to your gateway ' s trust store for mTLS is optional unless you need to reject certificates that do not contain particular values (such as a domain name).
B. Once the mTLS request policy is enabled, ALL requests with valid certificates are routed to the backend unless you have defined one or more particular values (such as a domain name).
C. The mTLS request policy can only be enabled at the API deployment specification level, which then applies globally to ALL routes in that deployment.
D. Custom CA or custom CA bundles can be added to your gateway ' s trust store ONLY if they already exist in the OCI Certificates service.
