Question 1

As a Cloud Native developer, you have written a web service for your company. However, your security team has suggested that your web service should address Distributed Denial-of-Service (DDoS) attack. You are time-constrained and you need to ensure that this is implemented as soon as possible. What should you do in this scenario? (Choose the best answer.)

A. Use the OCI Virtual Cloud Network (VCN) segregation to control DDoS.

B. Re-write your web service and implement rate limiting.

C. Use the OCI API Gateway service and configure rate limiting.

D. Use a third party service integration to Implement DDoS attack mitigation.

Question 2

As a cloud-native developer, you are designing an application that depends on Oracle Cloud Infrastructure (OCI) Object Storage wherever the application is running. Therefore, provisioning of storage buckets should be part of your Kubernetes deployment process for the application. Which of the following should you leverage to meet this requirement? (Choose the best answer.)

A. Open Service Broker API

B. Oracle Functions

C. OCI Container Engine for Kubernetes

D. OCI Service Broker for Kubernetes

Question 3

Which of the following is NOT a criterion that is usually met by a microservice?

A. Organized around business capabilities.

B. Highly maintainable

C. Tightly coupled

D. Independently deployable

Question 4

Which statement is NOT valid regarding the design best practices for microservices?

A. Backward compatibility dictates that API updates and parameter changes must not break existing clients consuming the microservice.

B. Responsive microservices must return a standard response to requesting clients even when the underlying service execution fails.

C. Idempotency ensures that calling a microservice multiple times with the same parameters produces the exact same outcome.

D. Flexible communication requires all microservices to use the same synchronous protocol for both external and internal communication.

Question 5

To effectively test your cloud native applications for " unknown unknowns " , you need to employ various testing and deployment strategies. Which strategy involves exposing new functionality or features to only a small set of users?

A. Component Testing

B. Blue/Green Deployment

C. A/B Testing

D. Canary Deployment

Question 6

You are developing an asynchronous, decoupled billing microservice that consumes payment messages from an Oracle Cloud Infrastructure (OCI) Queue. You notice that some corrupted payment payloads are causing the consumer application to fail and restart repeatedly, leaving the messages unprocessed and blocking the queue. To isolate these toxic messages, you want to redirect them to a Dead Letter Queue (DLQ) after 5 failed delivery attempts.
Which TWO configuration steps or characteristics must you apply to implement this solution?

A. Modify the " Maximum delivery attempts " setting of the queue to 5.

B. Configure an IAM policy specifically allowing the source queue to write to a target DLQ queue.

C. A dead letter queue is automatically created when you create the queue, so no manual DLQ resource creation is required.

D. A separate target queue must be manually created first and then selected as the designated Dead Letter Queue.

E. Enable consumer groups on the queue because DLQ functionality is only supported when utilizing consumer groups.

Question 7

You are developing a cloud native serverless application where uploaded PDF documents inside an OCI Object Storage bucket must automatically trigger an OCI Function for text processing. You have created an OCI Events rule configured with the condition eventType: com.oraclecloud.objectstorage.createbucket matching the bucket ' s compartment. However, when test files are uploaded, the function does not trigger.
Which TWO actions must you perform to successfully implement and troubleshoot this event-driven integration?

A. Enable the " Emit Object Events " setting on the source Object Storage bucket.

B. Verify the rule ' s condition is configured with the com.oraclecloud.objectstorage.createobject event type rather than com.oraclecloud.objectstorage.createbucket.

C. Set up a VCN Service Gateway because OCI Events cannot access Object Storage buckets over the public internet.

D. Define a dynamic group for the Object Storage bucket to allow it to invoke the targeted Oracle Function.

E. Create an IAM policy allowing the OCI Events service to read objects in the specific Object Storage bucket.

Question 8

Which of the following TWO statements are TRUE about deleting a Kubernetes cluster? (Choose two.)

A. Upon deleting a cluster, other resources created during the cluster creation process or associated with the cluster (such as VCNS, Internet Gateways, NAT Gateways, Route Tables, Security Lists, B. Load Balancers, and Block Volumes) are deleted automatically.

B. If you change the auto-generated name of a worker node and then delete the cluster, the renamed worker node is not deleted.

C. You cannot change the autogenerated names of the worker nodes in the format oke-c < part-of cluster- CCID > - < part-of-node-pool-OCID > - < part-of-subnet-OCID > - < slot > within a Kubernetes cluster.

D. Changing the auto-generated name of a worker node does not affect the deletion of the worker node when the cluster in which it is created is deleted.

E. Upon deleting a cluster, no other resources created during the cluster creation process or associated with the cluster (such as VCNS. Internet Gateways, NAT Gateways, Route Tables, Security Lists. Load Balancers, and Block Volumes) are deleted automatically.
