Oracle Cloud Infrastructure Developer Professional Sample Questions (Q166-Q171):

NEW QUESTION # 166
Which statement is NOT valid regarding the comparison between cloud-native and cloud-based applications?

A. Cloud-native applications require manual host provisioning to scale their compute resources, whereas cloud-based applications scale automatically and dynamically by default.
B. Cloud-native applications are built specifically for the cloud to minimize dependencies, whereas cloud- based applications are legacy systems modified to run in a cloud environment.
C. Cloud-native applications leverage pay-as-you-go pricing to optimize resource costs, whereas cloud- based applications can incur unnecessary expenses due to over-provisioning.
D. Cloud-native applications utilize a microservices architecture to reduce the risk of downtime, whereas cloud-based applications are often more vulnerable to central failure points.

Answer: A

Explanation:
Option C reverses a fundamental cloud-native characteristic. Oracle describes cloud-native applications as being designed for automated scale-up and scale-down in response to changing workload demand.
Technologies including containers, Kubernetes, serverless architectures, microservices, and automated DevOps processes are specifically intended to reduce manual infrastructure management. Oracle also identifies scalability, resilience, reduced operational overhead, and cost optimization through cloud consumption models as major cloud-native advantages. Applications migrated to cloud infrastructure without substantial architectural modernization can retain monolithic dependencies, fixed capacity assumptions, and manual provisioning practices. Therefore, claiming that cloud-native applications require manual host provisioning while cloud-based applications automatically scale by default is technically inverted. C is consequently the NOT valid statement among the available choices.

NEW QUESTION # 167
Which statement is NOT valid regarding the filter matching behavior of Oracle Cloud Infrastructure (OCI) Events rules?

A. For a filter to match an event, the event must contain all the field names listed in the filter with the same nesting structure.
B. Rules apply to events in the compartment in which they are created and any child compartments.
C. A filter matches all event messages in a compartment when configured with only empty curly brackets.
D. Asterisk wildcards can be placed at the start, middle, or end of both attribute keys and attribute values.

Answer: D

Explanation:
Oracle ' s Events documentation explicitly states that wildcard matching with * is supported only inattribute values, not in attribute keys. The asterisk can appear at the beginning, middle, or end of a value, but field names themselves must remain literal. Oracle also confirms all three other behaviors. An empty {} condition matches every applicable event; Events rules apply to their compartment and child compartments; and an event must contain every field named in the condition using the same nesting structure. Therefore, option C improperly extends wildcard functionality to attribute keys. The valid model is to preserve the exact JSON field structure while applying wildcard patterns only to values associated with those fields.

NEW QUESTION # 168
You are instructed to automate manual tasks and help software teams manage complex environments at scale using the Oracle Cloud Infrastructure (OCI) services. Which THREE OCI services can be leveraged to securely store and version your application ' s source code, and automate the building, testing, and deployment of applications to the OCI platform? (Choose three.)

A. Container Engine for Kubernetes
B. Oracle APEX Application Development
C. Oracle Cloud Logging Analytics
D. DevOps
E. Oracle Cloud Infrastructure Registry
F. Resource Manager

Answer: A,D,E

Explanation:
The three OCI services that can be leveraged to securely store and version your application ' s source code, and automate the building, testing, and deployment of applications to the OCI platform are: DevOps: OCI provides a comprehensive set of DevOps services, including Oracle Developer Cloud Service, which allows you to manage source code repositories, automate builds and testing, and streamline the deployment process.
Container Engine for Kubernetes: OCI ' s Container Engine for Kubernetes (OKE) enables you to deploy and manage containerized applications using Kubernetes. It provides a scalable and reliable platform for automating the deployment of your applications. Oracle Cloud Infrastructure Registry: OCI Registry is a fully managed, private container registry that allows you to securely store and manage Docker images. It integrates with other OCI services, such as Container Engine for Kubernetes, to facilitate seamless deployment and orchestration of containerized applications. These services combined provide the necessary tools and infrastructure to support continuous integration and continuous deployment (CI/CD) workflows, enabling efficient and automated application development and deployment processes in the Oracle Cloud Infrastructure environment.

NEW QUESTION # 169
You are a developing a microservices application that will be a consumer of the Oracle Cloud Infrastructure (OCI) Streaming service. Which API method should you use to read and process a stream?

A. ReadStream
B. GetStream
C. ReadMessages
D. ProcessStream
E. GetMessages

Answer: E

Explanation:
The correct API method to read and process a stream in the Oracle Cloud Infrastructure (OCI) Streaming service is " GetMessages " . When consuming messages from a stream in OCI Streaming, you use the " GetMessages " API method. This method allows you to retrieve a batch of messages from the stream for processing. You can specify parameters such as the number of messages to retrieve, the maximum size of the messages, and the timeout for the request. By using the " GetMessages " API method, you can retrieve messages from the stream and then process them in your microservices application. This allows you to consume and handle the data in real-time as it becomes available in the stream. The " GetMessages " method provides flexibility in how you consume and process the messages, enabling you to implement custom logic and workflows based on your specific application requirements.

NEW QUESTION # 170
Which statement is NOT valid regarding OCI Identity and Access Management (IAM) policies written for OKE Workload Identity?

A. The policy condition must specify the Kubernetes namespace, service account name, and OKE cluster OCID.
B. The policy statement must be scoped strictly at the tenancy level and cannot be written to restrict access to a specific compartment.
C. The policy subject must be specified as any-user rather than a specific IAM group or dynamic group name.
D. The policy condition must explicitly define request.principal.type with the value set to workload.

Answer: B

Explanation:
Oracle ' s documented OKE Workload Identity policy pattern is Allow any-user to < verb > < resource > in < location > where all {...} with conditions identifying request.principal.type= ' workload ' , the Kubernetes namespace, service account, and cluster OCID. Crucially, Oracle defines < location > as either the entire tenancyor a specific compartment. Oracle even provides examples granting a workload access only to resources in a named compartment. Consequently, C is false because workload-identity policies do not have to be tenancy-wide. Options A, B, and D accurately describe the standard policy structure: any-user is narrowed through workload-specific conditions, and those conditions identify the exact OKE workload by cluster, namespace, and service account. This enables fine-grained least-privilege access without storing OCI credentials inside pods.
