NEW QUESTION # 165
Which statement is NOT valid regarding the design best practices for microservices?
Answer: D
Explanation:
Oracle ' s microservices design guidance explicitly identifies responsive behavior, backward compatibility, flexible communication, and idempotency as important requirements. Flexible communication doesnotrequire every microservice to use one synchronous protocol. Oracle states that each microservice can specify the protocol used between clients and the API gateway as well as the protocol used between individual microservices. This flexibility supports loose coupling and allows synchronous or asynchronous communication where appropriate. Oracle also states that microservices should return a response even when the service fails, API changes should remain backward-compatible with existing clients, and repeated calls should produce the same outcome when idempotency is required. Consequently, option C directly contradicts Oracle ' s documented flexible-communication principle and is the NOT valid statement.

Kubernetes includes various elements such as compute, network, and storage. Compute is essentially CPU (units) and memory (bytes). Within an OKE cluster, what is considered to be the smallest unit of deployment with respect to compute?
Answer: E
Explanation:
A pod is the smallest and simplest unit in the Kubernetes object model that you create or deploy2. A pod represents a single instance of a running process in your cluster. Pods contain one or more containers, such as Docker containers. When you create a pod, you define how much CPU and memory (RAM) each container needs. A pod can also include storage volumes, IP addresses, options that govern how the container(s) should run, and more2. Pods are the basic building blocks of larger Kubernetes constructs such as deployments, replica sets, and services2.
NEW QUESTION # 167
Which statement is NOT valid regarding testing methodologies for cloud native applications?
Answer: D
Explanation:
Statement D is NOT valid. Oracle ' s cloud application architecture guidance explicitly describes integration testing as validating interactions and data flow between components, modules, and services. In a cloud-native architecture, those interactions commonly occur through network-based APIs, service endpoints, databases, and messaging systems. Oracle recommends test environments that resemble production rather than restricting integration testing to isolated developer workstations. Unit testing does focus on individual units of code and typically isolates dependencies. API mocking can emulate unavailable dependent services, while performance testing evaluates responsiveness, scalability, and stability under varying workloads such as load and stress conditions. Therefore, the claim that integration testing is exclusively local and does not validate network communication contradicts the actual purpose of integration testing.
NEW QUESTION # 168
You are building a cloud native serverless travel application with multiple Oracle Functions in Java, Python, and Node.js. You need to build and deploy these functions to a single application named travel-app. Which command will help you complete this task successfully?
Answer: A
Explanation:
The correct answer is: fn deploy --app travel-app --allExplanation: To build and deploy multiple Oracle Functions as part of a single application named " travel-app, " you can use the fn deploy command with the appropriate options. The command fn deploy --app travel-app --all is the correct syntax. Here ' s what each part of the command does: fn deploy: This command is used to deploy functions and applications in Oracle Functions. --app travel-app: This option specifies the application name as " travel-app, " indicating that you want to deploy functions to this application. --all: This option indicates that you want to deploy all the functions within the application. By using fn deploy --app travel-app --all, you can build and deploy all the functions in your travel application across different programming languages (Java, Python, and Node.js) to the " travel-app " application in Oracle Functions.
NEW QUESTION # 169
Your organization has deployed a custom OCI Authorizer Function in a compartment named secure-auth- compartment to perform token-based validation for all ingress traffic. You have set up an API Gateway in a compartment named public-gateway-compartment with an associated dynamic group named apigw-dg containing the gateway instance. The API Gateway deployment is currently returning HTTP 500 errors because the gateway lacks the necessary permissions to invoke the authorizer function during request validation. Which minimal IAM policy statement should you write to grant the API Gateway the required permission to successfully invoke the authorizer function?
Answer: C
Explanation:
Oracle ' s documented API Gateway-to-Functions integration uses a dynamic group representing the API Gateway and an IAM policy granting that dynamic group use functions-family in the compartment containing the target Function. The use verb provides the operational permission necessary for invocation without granting unnecessary administrative control. manage functions-family would be excessively privileged because it includes lifecycle management capabilities. The read and inspect verbs are insufficient for executing a Function and, in options C and D, are also scoped to the wrong compartment. Because the authorizer resides in secure-auth-compartment, authorization must apply there. Consequently, A implements the Oracle-documented pattern and satisfies least privilege for API Gateway invocation of the custom authorizer Function.
