問題 #98
Which matching behavior occurs when an Oracle Cloud Infrastructure (OCI) Events rule condition defines an attribute value containing only a single asterisk (*) wildcard?
答案:D
解題說明:
Oracle ' s Events filtering documentation explicitly defines the behavior of a standalone asterisk wildcard.
When an attribute value consists only of *, it matchesall values for that attribute except null. The field must therefore exist and contain a non-null value for the rule condition to match. Oracle permits wildcard characters only in attribute values, and an asterisk can otherwise appear at the beginning, middle, or end of a value pattern. It is not interpreted as a literal asterisk in this context, nor is it restricted to matching empty strings. Option A is incorrect because null values are excluded. Therefore, option B precisely reflects Oracle ' s documented Events rule wildcard semantics.
問題 #99
Which TWO are characteristics of microservices? (Choose two.)
答案:C,E
解題說明:
The two characteristics of microservices are: Microservices can be independently deployed: One of the key principles of microservices architecture is the ability to independently deploy each microservice. This means that changes or updates to one microservice can be made and deployed without affecting other microservices.
It allows for faster and more frequent deployments, enabling agile development and scalability. Microservices communicate over lightweight APIs: Microservices communicate with each other through lightweight APIs (Application Programming Interfaces). This enables loose coupling between microservices, as they can interact with each other using standard protocols like HTTP/REST or messaging systems like RabbitMQ or Kafka. Lightweight APIs facilitate flexibility and interoperability between microservices, making it easier to develop and maintain complex systems. The remaining statement, " All microservices share a data store, " is not a characteristic of microservices. Microservices are designed to be autonomous and have their own data storage or database. Each microservice has its own data store, which promotes the principle of bounded contexts and avoids tight coupling between services. This allows for better scalability and independence of data management within each microservice.
問題 #100
You are deploying a serverless data integration pipeline where an OCI Function needs to consume real-time events from an OCI Stream in the prod-compartment compartment. Your corporate security policy mandates strict least-privilege access, meaning the function must only be permitted to consume (pull) messages, with absolutely no capability to publish (push) messages to the stream. Which TWO configurations are required to establish this granular authorization using a Dynamic Group named analytics-function-dg?
答案:C,D
解題說明:
Oracle Streaming exposes separate IAM resource types for producers and consumers. Granting use stream- pull provides STREAM_CONSUME, covering operations such as GetMessages, CreateCursor, group cursors, heartbeats, and commits without granting STREAM_PRODUCE. Granting use streams would be broader because that resource type includes both production and consumption capabilities. Oracle Functions can be placed in a dynamic group with a rule using resource.type = ' fnfunc ' together with the Function ' s compartment OCID. compute would not match an Oracle Function resource, and stream-push provides the opposite permission by allowing message publication. Therefore, A establishes consume-only Streaming permission while C correctly associates the Functions resources with the dynamic group.
問題 #101
Your company requires strict compartment isolation for an event-driven automation framework. You have deployed an Oracle Functions function inside a secure compartment named SecOps-Fn-Compartment. An OCI Events rule has been configured in a separate compartment named App-Resources-Compartment to capture critical resource state changes. Which configuration approach is required to allow the OCI Events service to successfully invoke your function?
答案:D
解題說明:
OCI Events invokes configured action resources as a managed service rather than by assuming the identity of the human user who created the rule. Oracle ' s Events material documents the service principal cloudEvents and the policy pattern allowing that service to use functions-family. Scoping that permission to the compartment containing the target Function provides the required compartment isolation. A dynamic group is inappropriate because an Events rule is not a Compute instance or workload principal. Granting permissions to oraclefunctions reverses the invocation relationship, while granting a user group broad function- management rights does not authorize the Events runtime itself. Current Oracle documentation additionally represents cross-tenancy delivery using an eventrule principal and FN_INVOCATION; within the source scenario, B is the intended service authorization model.
問題 #102
Which node configuration in Oracle Cloud Infrastructure Container Engine for Kubernetes provides a serverless experience with granular pod-level elasticity and billing?
答案:C
解題說明:
OKE Virtual Nodes provide Oracle ' s serverless Kubernetes execution model. Oracle manages the underlying node infrastructure, eliminating the need for customers to provision, patch, upgrade, scale, or troubleshoot conventional worker-node infrastructure. Resource allocation and elasticity occur at the pod level, allowing workloads to scale without planning the capacity of a conventional node pool. Oracle also describes Virtual Nodes as providing pay-per-use pricing based on the compute resources consumed by each Kubernetes pod rather than charging for entire worker servers that might contain unused capacity. Managed, bare metal, and self-managed nodes remain infrastructure-oriented worker-node models and therefore do not provide the same serverless pod-level operating model. Consequently, Virtual Nodes are the configuration designed for granular elasticity and pod-oriented consumption.
