질문 # 152
Which statement is NOT valid regarding pulling and pushing container images in Oracle Cloud Infrastructure Registry (OCIR)?

A. Images stored in public repositories can be pulled by any client with internet access without requiring a previous docker login authentication.
B. By default, executing a docker push command referencing a non-existent repository automatically creates a private repository in the user ' s home compartment.
C. Container Registry is compliant with the Open Container Initiative (OCI) specification, allowing developers to use standard Docker CLI commands to push and pull images.
D. To push a container image, you must tag the local image with a path that includes the registry ' s regional domain name and your tenancy ' s Object Storage namespace.

정답：B

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 # 153
(CHK_4 > 2) Which TWO statements are NOT valid regarding the Oracle Cloud Infrastructure (OCI) Streaming service? (Choose two.)

A. A stream can be configured with either a public or a private endpoint with support for customer managed encryption keys.
B. OCI Streaming can support up to 2,000 requests per second to each partition.
C. OCI Streaming stores all data for 24 hours by default, but that can be extended up to 7 days.B
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. The throughput of a stream is defined by a partition. A partition provides 1 MB/sec data input and 2 MB
/sec data output.

정답：A,B

설명：
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.

질문 # 154
You are planning the migration of a legacy monolithic billing application to a cloud-native architecture on Oracle Cloud Infrastructure. The application currently relies on a centralized relational database and synchronous local procedure calls, and you must address the primary architectural challenges associated with transitioning to a distributed microservices model.
Which TWO statements represent valid engineering challenges or design strategies that must be considered during this cloud-native migration?

A. Implementing microservices requires adopting eventual consistency patterns, such as the Saga pattern, because distributed databases cannot easily maintain synchronous transactions across service boundaries.
B. Cloud-native microservices must communicate using synchronous REST APIs exclusively, as asynchronous event-driven communication is not supported within OCI.
C. By default, OCI ensures that all distributed containerized microservices automatically share a single, global transaction state across different compartments without any application-level coding.
D. Monolithic databases migrated to OCI Object Storage will automatically scale horizontally and support distributed transactions natively for all microservices.
E. Transitioning to microservices increases the operational complexity of the application, necessitating centralized logging and distributed tracing to troubleshoot service-to-service communication.

정답：A,E

설명：
Oracle identifies distributed transaction consistency and observability as major concerns when moving from monoliths to microservices. The Saga pattern addresses cross-service business transactions by dividing them into local transactions and using events plus compensating actions, avoiding long-duration distributed locks.
Oracle also emphasizes unified observability for microservices, including metrics, logs, and traces, because failures become harder to diagnose when calls cross multiple networked services. OCI does not automatically create a global application transaction across compartments, Object Storage is not a transactional relational database replacement, and microservices are not restricted to synchronous REST communication. Oracle explicitly supports asynchronous messaging and event-driven designs for loose coupling. Therefore, A and B correctly describe realistic migration challenges and strategies.

질문 # 155
Your organization has deployed their e-commerce application on Oracle Container Engine for Kubernetes (OKE) and they are using the Oracle Cloud Infrastructure Registry (OCIR) service as their Docker image repository. They have deployed the OKE cluster using the ' custom create ' option, and their Virtual Cloud Network (VCN) has three public subnets with associated Route Tables, Security Lists, and Internet Gateway.
However, their application containers are failing to deploy. On investigation, they discover that the images are not being pulled from the designated OCIR repository, even though the YAML configuration has the correct path to the images. What is a valid concern here that needs to be further investigated?

A. Security List rule for TCP port 22 needs to be added to connect to the OCIR service.
B. VCN hosting the OKE cluster worker nodes needs to have a NAT gateway to access OCIR repositories.
C. OKE cluster needs to have a secret with the credentials of their OCIR repository and use that secret in the Kubernetes deployment manifest.
D. Identity and Access Management (IAM) credentials need to be added for each user that deploys applications to the OKE cluster.

정답：C

설명：
A valid concern that needs to be further investigated in this scenario is whether the OKE cluster has a secret with the credentials of the Oracle Cloud Infrastructure Registry (OCIR) repository and if that secret is being used in the Kubernetes deployment manifest. Here ' s why this concern is relevant: Access to the OCIR repository: In order for the OKE cluster to pull images from the OCIR repository, it needs proper authentication credentials. These credentials are typically provided in the form of a secret, which contains the necessary information to authenticate with the registry. Secret in the deployment manifest: The Kubernetes deployment manifest defines how the application containers should be deployed. It includes specifications such as the container image, resource requirements, and environment variables. To pull images from a private repository like OCIR, the deployment manifest needs to reference the appropriate secret that contains the registry credentials. If the images are not being pulled from the designated OCIR repository, it suggests that either the secret with the OCIR credentials is missing or it is not properly referenced in the deployment manifest. Further investigation should focus on verifying the presence and correctness of the secret, as well as confirming that it is correctly referenced in the deployment manifest for the application containers. By ensuring the presence of the secret and proper configuration in the deployment manifest, the OKE cluster will have the necessary credentials to access the OCIR repository and successfully deploy the application containers.

질문 # 156
Which " Action Type " option is NOT available in an Oracle Cloud Infrastructure (OCI) Events rule definition?

A. Notifications
B. Streaming
C. Functions
D. Email

정답：D

설명：
An action is a response that you define for the rule to perform when the filter finds a matching event1. The action type specifies the service that you want to invoke by delivering the event message1. The following action types are available in OCI Events rule definition1:
* Streaming: Send to a stream from Oracle Streaming Service.
* Notifications: Send to an Oracle Notification Service topic.
* Functions: Send to an Oracle Functions Service endpoint. Email is not a valid action type for OCI Events rule definition. To send an email as an action, you need to use the Notifications service and subscribe to a topic with an email protocol2.
