Oracle Cloud Infrastructure 2025 Developer Professional Sample Questions (Q30-Q35):

NEW QUESTION # 30
Which THREE are valid statements regarding the OCI Container Engine for Kubernetes (OKE) service? (Choose three.)

A. OKE cannot use existing network resources for the creation of a new cluster.
B. There is a limit of three clusters within each region, but there is no limit on the number of nodes and pods you can create within each cluster.
C. OKE automatically creates and configures new network resources for the new cluster.
D. You must have access to an Oracle Cloud Infrastructure tenancy. Your tenancy must have sufficient quota on different types of resources.

Answer: B,C,D

Explanation:
The valid statements regarding the OCI Container Engine for Kubernetes (OKE) service are: OKE automatically creates and configures new network resources for the new cluster. When creating a new OKE cluster, the service automatically provisions and configures the necessary network resources, such as VCNs, subnets, route tables, security lists, and load balancers, to support the cluster. Your tenancy must have sufficient quota on different types of resources. Before creating an OKE cluster, you need to ensure that your Oracle Cloud Infrastructure (OCI) tenancy has sufficient quota for the required resources, such as compute instances, block storage, networking resources, and load balancers. You must have access to an Oracle Cloud Infrastructure tenancy. To use the OKE service, you need to have access to an OCI tenancy. This means you must have a valid OCI account and the necessary permissions to create and manage resources within the tenancy. The following statements are not valid: OKE cannot use existing network resources for the creation of a new cluster. OKE creates new network resources specifically for the cluster, and it does not support using existing network resources. There is a limit of three clusters within each region, but there is no limit on the number of nodes and pods you can create within each cluster. This statement is incorrect. There is no specific limit on the number of clusters you can create within a region in OKE. However, there may be certain limits or quotas on resources that can impact the number of clusters you can create.

NEW QUESTION # 31
Which command is used to get a Docker image from Oracle Cloud Infrastructure Registry (OCIR) to the client machine?

A. docker fetch <region-key>.ocir.io/<tenancy-namespace>/<repo-name>:<tag>
B. docker pull <region-key>.ocir.io/<tenancy-namespace>/<repo-name>: <tag>
C. docker fetch <tenancy-namespace>/<region-key>.ocir.io/<repo-name>:<tag>
D. docker pull <tenancy-namespace>/<region-key>.ocir.io/<repo-name>: <tag>

Answer: B

Explanation:
To pull a Docker image from OCI Registry to the client machine, you need to use the docker pull command with the following syntax1: docker pull <region-key>.ocir.io/<tenancy-namespace>/<repo-name>:<tag> where:
<region-key> is the key for the OCI Registry region you're using. For example, iad. See Availability by Region1.
ocir.io is the OCI Registry name.
<tenancy-namespace> is the auto-generated Object Storage namespace string of the tenancy that owns the repository from which you want to pull the image (as shown on the Tenancy Information page)1.
<repo-name> is the name of the repository that contains the image you want to pull.
<tag> is the tag of the image you want to pull.

NEW QUESTION # 32
Which of the following is NOT a criterion that is usually met by a microservice?

A. Independently deployable
B. Highly maintainable
C. Organized around business capabilities.
D. Tightly coupled

Answer: D

Explanation:
The correct answer is: "Tightly coupled." Tightly coupling is not a criterion that is usually met by a microservice. In fact, microservices are designed to be loosely coupled. Loosely coupling refers to reducing dependencies and minimizing the direct interactions between different components or services. Microservices promote independence and autonomy, allowing each service to operate independently without being tightly bound to other services. The other options listed are criteria that are typically met by microservices: Organized around business capabilities: Microservices architecture suggests designing services around specific business capabilities or functionalities. This allows for focused and specialized services that align with the organization's business needs. Independently deployable: Microservices are designed to be independently deployable units. Each microservice can be developed, tested, and deployed separately, without impacting other services. This enables agility and scalability in the deployment process. Highly maintainable: Microservices are often designed to be highly maintainable. They are smaller in scope and focused on specific tasks, making it easier to manage and maintain individual services. Additionally, microservices can be updated, patched, or replaced without affecting the entire system, facilitating easier maintenance and evolution of the application. Therefore, the criterion that is NOT typically met by a microservice is being tightly coupled.

NEW QUESTION # 33
(CHK_4>2) Which TWO statements are NOT valid regarding the Oracle Cloud Infrastructure (OCI) Streaming service? (Choose two.)

A. OCI Streaming can support up to 2,000 requests per second to each partition.
B. A stream can be configured with either a public or a private endpoint with support for customer managed encryption keys.
C. The throughput of a stream is defined by a partition. A partition provides 1 MB/sec data input and 2 MB/sec data output.
D. Although OCI Streaming automatically encrypts all data while in transit, it is the developer's responsibility to encrypt data at rest, if needed.
E. OCI Streaming stores all data for 24 hours by default, but that can be extended up to 7 days.B

Answer: A,B

Explanation:
The two statements that are NOT valid regarding the Oracle Cloud Infrastructure (OCI) Streaming service are: A stream can be configured with either a public or a private endpoint with support for customer managed encryption keys. This statement is not valid because the OCI Streaming service currently supports only private endpoints. Customer managed encryption keys are not currently supported for OCI Streaming. OCI Streaming can support up to 2,000 requests per second to each partition. This statement is not valid because the throughput of a stream is not defined by the partition in terms of requests per second. The throughput of a stream is defined in terms of data input and output rates. Each partition provides 1 MB/sec data input and 2 MB/sec data output, but it does not correspond to a specific number of requests per second. The other statements are valid: OCI Streaming stores all data for 24 hours by default, but that can be extended up to 7 days. Although OCI Streaming automatically encrypts all data while in transit, it is the developer's responsibility to encrypt data at rest, if needed.

NEW QUESTION # 34
Which of the following is defined as a configurable, low-latency infrastructure layer that controls the interaction between a network of microservices? (Choose the best answer.)

A. DevOps
B. Service Mesh
C. CI/CD Pipelines
D. Containers
E. Kubernetes

Answer: B

Explanation:
The correct answer is "Service Mesh." A service mesh is a configurable, low-latency infrastructure layer that controls the interaction between a network of microservices. It provides functionalities such as service discovery, load balancing, traffic management, security, and observability for microservices-based applications. It is designed to improve communication and manage the complex interactions between services within a distributed system. Service mesh frameworks like Istio and Linkerd are commonly used to implement service mesh architecture.
