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?

1. 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.
2. B. Create a separate load balancer instance for each service using the lowest 100 Mbps option.
3. C. Use a ClusterIP service type in Kubernetes for each of your service endpoints using a load balancer to expose the endpoints.
4. D. Deploy an Ingress Controller and use it to expose each endpoint with its own routing endpoint.

Correct Answer: D

A developer has created another version of a microservice and wants 10% of the traffic to flow towards it for testing purposes. The application is already configured using OCI (Oracle Cloud Infrastructure) Service Mesh. Which of the following steps is the right approach to achieve this goal?

1. A. Create a new Kubernetes deployment for the new version of the microservice and set the traffic splitting percentage to 10% in the Kubernetes service manifest.
2. B. Use Kubernetes HPA (Horizontal Pod Autoscaler) to scale the new version of the microservice to handle 10% of the traffic automatically.
3. C. Create a new entry in the routeRules field of the ingress gateway route table manifest to configure traffic splitting between the old and new versions of the microservice and set the percentage to 10%.
4. D. Create a new entry in the routeRules field of the virtual service route table manifest to configure traffic splitting between the old and new versions of the microservice and set the percentage to 10%.

Correct Answer: D

Which open source engine is used by Oracle Cloud Infrastructure (OCI) to power Oracle Functions?

1. A. Knative
2. B. Kubeless
3. C. Apache OpenWhisk
4. D. Fn Project

Correct Answer: D

You are developing a serverless application with Oracle Functions and Oracle Cloud Infrastructure Object Storage. Your function needs to read a JSON file object from an Object Storage bucket named "input-bucket" in compartment "qa-compartment". Your corporate security standards mandate the use of Resource Principals for this use case. Which two statements are needed to implement this use case? (Choose two.)

1. A. Set up a policy to grant all functions read access to the bucket: allow all functions in compartment qa-compartment to read objects in target.bucket.name= "input-bucket'
2. B. Set up a policy to grant your user account read access to the bucket: allow user XYZ to read objects in compartment qa-compartment where target.bucket.name= "input-bucket'
3. C. Set up the following dynamic group for your function's OCID: Name: read-file-dg Rule: resource.id = "ocid1.fnfunc.oc1.phx.aaaaaaaakeaobctakezjz5i4ujj7g25q7sx5m vr55pms6f4da'
4. D. No policies are neede
5. E. By default, every function has read access to Object Storage buckets in the tenancy.
6. F. Set up a policy with the following statement to grant read access to the bucket: allow dynamic-group read-file-dg to read objects in compartment qa- compartment where target.bucket.name= 'input-bucket'

Correct Answer: CE

3. C. All microservices share a data store.
4. D. Microservices are hard to test in isolation.
5. E. Microservices can be independently deployed.
