Oracle Cloud Infrastructure Developer Professional Sample Questions:

Question #1
Which annotation is required in a Kubernetes Service manifest of type LoadBalancer to provision a private load balancer rather than a public load balancer?

A. service.beta.kubernetes.io/oci-load-balancer-scheme: " internal "
B. service.beta.kubernetes.io/oci-load-balancer-internal: " true "
C. service.beta.kubernetes.io/oci-load-balancer-private: " true "
D. service.beta.kubernetes.io/oci-load-balancer-type: " private "

Question #2
Which statement is NOT valid regarding the structure and behavior of Docker images and containers?

A. Modifying an existing file within a running container copies the file from the read-only layer to the writable layer.
B. Running a Docker container adds a thin writable layer on top of the underlying read-only image layers.
C. Deleting a Docker container also permanently deletes the underlying image from the host system by default.
D. A Docker image is composed of a series of read-only layers that represent filesystem differences.

Question #3
You are tasked with developing an application that requires the use of Oracle Cloud Infrastructure (OCI) APIs to POST messages to a stream in the OCI Streaming service. Which statement is incorrect? (Choose the best answer.)

A. An HTTP 401 will be returned if the client ' s clock is skewed more than 5 minutes from the server ' s.
B. The request must include an authorization signing string including (but not limited to) x-content- sha256, content-type, and content-length headers.
C. The Content-Type header must be set to application/json
D. The request does not require an Authorization header.

Question #4
Which statement is NOT valid regarding testing methodologies for cloud native applications?

A. Integration testing is conducted exclusively on isolated local workstations and does not validate network-based communications.
B. Unit testing focuses on validating individual blocks of code in complete isolation from database and external API dependencies.
C. Performance testing evaluates system responsiveness under concurrent workloads to identify potential resource bottlenecks.
D. API mocking allows developers to validate a service ' s logic by simulating the behavior of dependent microservices that are offline.

Question #5
Your organization is deploying a high-performance distributed deep learning training workload that requires GPU-enabled bare metal Compute instances connected through an ultra-low-latency Oracle Cloud Infrastructure (OCI) RDMA cluster network. To maximize processing efficiency and comply with strict corporate OS requirements, your team must use a custom, pre-hardened Oracle Linux operating system image that is not supported by default node pools. The containerized training jobs must be orchestrated and scheduled using your existing Container Engine for Kubernetes (OKE) control plane.
Which worker node deployment model must you implement?

A. Managed Node Pools
B. Self-Managed Nodes
C. Virtual Node Pools
D. Instance-Pool Nodes
