質問 3：
You developed a microservices-based application that runs in an Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster. It has multiple endpoints that need to be exposed to the public internet. What is the most cost-effective way to expose multiple application endpoints without adding unnecessary complexity to the application?
A. Create a separate load balancer instance for each service using the lowest 100 Mbps option.
B. Use a NodePort service type in Kubernetes for each of your service endpoints using the node's public IP address to access the applications.
C. Use a ClusterIP service type in Kubernetes for each of your service endpoints using a load balancer to expose the endpoints.
D. Deploy an Ingress Controller and use it to expose each endpoint with its own routing endpoint.

質問 4：
In the DevOps lifecycle, what is the difference between continuous delivery and continuous deployment? (Choose two.)
A. Continuous delivery requires more automatic linting, while continuous deployment testing must be run manually.
B. Continuous delivery utilizes automatic deployment to a development environment, while continuous deployment involves automatic deployment to a production environment.
C. Continuous delivery involves automation of developer tasks, while continuous deployment involves manual operational tasks.

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

質問 6：
You are developing a real-time monitoring application for a fleet of vehicles, which will be deployed on Oracle Cloud Infrastructure (OCI). You need to choose between using OCI Queue or OCI Streaming to handle the real-time data feeds from the vehicles. Based on the scenario described, which is the most appropriate choice for handling real-time data feeds?
A. OCI Queue, because it provides at-least-once message delivery, which is critical for real-time monitoring applications
B. OCI Streaming, because it is designed for high-volume, continuous ingestion and processing of data, making it the best choice for a fleet of vehicles
C. OCI Streaming, because it offers exactly-once message delivery, which is necessary for real-time applications
D. OCI Queue, because it is optimized for low-latency messaging and ideal for real-time applications
正解：B

質問 7：
Which testing measure should be considered when using test cases that simultaneously validate a deployment and perform a selected set of functional tasks?
A. Robust Deployment
B. Resource Utilization
C. Scalability
D. Functionality
E. Resiliency
正解：A
