Question 1

With the volume of communication that can happen between different components in cloud-native applications, it is vital to not only test functionality, but also service resiliency. Which statement is true regarding service resiliency?

Options :

A : Resiliency is about recovering from failures without downtime or dataloss.

B : A goal of resiliency is not to bring a service to a functioning state after a failure.

C : Resiliency testing can be only done in a test environment.

D : Resiliency is about avoiding failures.

Answer: A

Question 2

Which TWO statements are true for serverless computing and serverless architectures? (Choose two.)

Options :

A : Serverless function execution is fully managed by third party.

B : Applications running on a FaaS (Functions as a Service) platform.

C : Long running tasks are perfectly suited for serverless.

D : Application DevOps team is responsible for scaling.

E : Serverless function state should never be stored externally.

Answer: A,B

Question 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?

Options :

A : Use a NodePort service type in Kubernetes for each of your service endpoints using the node-s public IP address to access the applications.

B : Create a separate load balancer instance for each service using the lowest 100 Mbps option.

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.

Answer: D

Question 4

You are developing a polyglot serverless application using Oracle Functions. Which language cannot be used to write your function code?

Options :

A : PL/SQL

B : Python

C : Node.js

D : Java

Answer: A

Question 5

You have a containerized application that requires access to an Autonomous Transaction Processing (ATP) Database. Which option is NOT valid when the container is deployed in an OKE cluster? (Choose the best answer.)

Options :

A : Use Kubernetes secrets to configure environment variables on the container with ATP instance OCID, and OCI API credentials. Then use the CreateConnection API endpoint from the service runtime.

B : Install the Oracle Cloud Infrastructure Service Broker on the Kubernetes cluster and deploy ServiceInstance and ServiceBinding resources for ATP. Then use the specified binding name as a volume in the application deployment manifest

C : Create a Kubernetes secret with contents from the instance Wallet files. Use this secret to create a volume mounted to the appropriate path in the application deployment manifest.

D : Enable Oracle REST Data Services for the required schemas and connect via HTTPS.

Answer: B
