질문 # 40
Which statement is NOT valid regarding pulling and pushing container images in Oracle Cloud Infrastructure Registry (OCIR)?
정답：A
설명：
Statement C is invalid. Oracle states that creating a repository before pushing is the normal workflow.
Automatic repository creation occurs only when the tenancy settingCreate repository on first push in root compartmentis enabled and the user has appropriate permissions. Even then, the new private repository is created in the tenancy ' sroot compartment, not a user ' s "home compartment." Oracle Container Registry is OCI-compliant and supports standard Docker commands. Public repositories can be pulled by anyone with internet access and the appropriate image URL without authenticating first. For pushing, Docker images are tagged using a registry path containing the regional registry domain, tenancy namespace, repository name, and version. The tenancy namespace is the automatically generated namespace associated with Object Storage. Therefore, C misstates both the default behavior and repository location.
질문 # 41
Which container network interface plugin must be selected when creating an Oracle Cloud Infrastructure Container Engine for Kubernetes cluster that requires pod IP addresses to be directly routable from peered virtual cloud networks and on-premises environments?
정답：C
설명：
The OCI VCN-Native Pod Networking CNI plugin assigns pod IP addresses directly from the OCI VCN address space instead of allocating addresses from a separate overlay network. Oracle specifically states that these pod IP addresses are directly routable from other VCNs connected through VCN peering and from on- premises networks. This architecture makes pods first-class participants in OCI networking and enables native VCN functionality such as network security groups, security lists, and VCN flow logs to be applied to pod traffic. Flannel uses an overlay model and therefore does not provide the required directly routable VCN pod addresses. Calico is commonly associated with Kubernetes NetworkPolicy enforcement rather than being the required OCI native routing CNI. Therefore, D is correct.
질문 # 42
You plan to implement logging in your services that will run in Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). Which statement describes the appropriate logging approach?
정답：B
설명：
The appropriate logging approach for services running in Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) is: " All services log to standard output only. " When running services in a containerized environment like OKE, it is recommended to follow the Twelve-Factor App methodology, which suggests treating logs as event streams. According to this methodology, services should write their log events to standard output (stdout) instead of writing to log files. By logging to standard output, the container runtime (such as Kubernetes) can collect and aggregate the logs generated by the services. These logs can then be accessed and managed through the container runtime ' s logging infrastructure. Logging to standard output offers several advantages in a containerized environment: Simplicity and consistency: Standardizing on logging to stdout ensures a consistent approach across different services, making it easier to manage and analyze logs. Log aggregation: The container runtime can collect the logs from all the running containers and provide centralized log management, allowing you to access and search logs from different services in one place. Scalability: Since logs are written to stdout, they can be easily handled by the container runtime ' s log management system, which can scale to handle large volumes of log data. Separation of concerns: By logging to stdout, the responsibility of managing log files and their rotation is shifted to the container runtime, allowing the services to focus on their core functionality. While it is possible to log to log files or external logging systems, the recommended approach in a containerized environment like OKE is to log to standard output and leverage the logging infrastructure provided by the container runtime.
질문 # 43
You have two microservices, A and B, running in production. Service A relies on APIs from service B. You want to test changes to service A without deploying all of its dependencies, which include service B. Which approach should you take to test service A?
정답：A
설명：
API mocking is a technique that simulates the behavior of real APIs without requiring the actual implementation or deployment of the dependent services1. API mocking allows you to test changes to service A without deploying all of its dependencies, such as service B, by creating mock responses for the APIs that service A relies on1. API mocking has several benefits, such as1:
* Faster testing: You can test your service A without waiting for service B to be ready or available, which reduces the testing time and feedback loop.
* Isolated testing: You can test your service A in isolation from service B, which eliminates the possibility of external factors affecting the test results or causing errors.
* Controlled testing: You can test your service A with different scenarios and edge cases by creating mock responses that mimic various situations, such as success, failure, timeout, etc.
질문 # 44
How are cloud native application versions deployed to an OKE cluster when using a blue/green deployment strategy?
정답：B
설명：
Blue/Green deployment strategy allows releasing a new version of an application using two identical environments where one of them is active at a given time. The current version of the application is provisioned on the active environment, whereas the new version gets deployed to the standby environment1. The traffic is shifted from the active to the standby environment by updating the ingress resource2. Therefore, both old and new application versions are deployed to production at the same time, but only one of them receives the traffic.
