Question # 1

Which THREE are valid statements regarding the OCI Container Engine for Kubernetes (OKE) service? (Choose three.)

A.

You must have access to an Oracle Cloud Infrastructure tenancy. Your tenancy must have sufficient quota on different types of resources.

B.

OKE cannot use existing network resources for the creation of a new cluster.

C.

OKE automatically creates and configures new network resources for the new cluster.

D.

There is a limit of three clusters within each region, but there is no limit on the number of nodes and pods you can create within each cluster.

Question # 2

What is the open source engine for Oracle Functions?

A.

Fn Project

B.

Apache OpenWhisk

C.

OpenFaas

D.

Knative

Question # 3

Which configuration parameter defines the duration a message remains inside an Oracle Cloud Infrastructure (OCI) Queue before being automatically deleted by the service if it is not consumed?

A.

Visibility timeout

B.

Maximum retention period

C.

Maximum delivery attempts

D.

Polling timeout

Question # 4

You are designing an automated integration testing strategy for a containerized microservice deployed to an Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster. The microservice ' s integration tests must write test events to an OCI Stream within a specific compartment. To comply with security mandates, you must avoid the use of hardcoded credentials, long-lived API signing keys, or manual token injection during the automated test execution. Which TWO configurations are required to securely authorize the test suite to access the OCI Streaming service? (Choose TWO.)

A.

Create a dynamic group that matches the OKE worker node instances using a rule such as instance.compartment.id = ' < compartment-ocid > ' .

B.

Define an IAM policy that allows the dynamic group to use the streaming resources in the target compartment.

C.

Generate an OCI Auth Token and hardcode it in the application ' s configuration secrets.

D.

Configure the test suite to run with root user privileges on the OKE worker node to bypass OCI API signature requirements.

E.

Set up a security list to allow public, unauthenticated access to the streaming endpoint from the OKE subnet.

Question # 5

Which node configuration in Oracle Cloud Infrastructure Container Engine for Kubernetes provides a serverless experience with granular pod-level elasticity and billing?

A.

Managed Nodes

B.

Bare Metal Nodes

C.

Virtual Nodes

D.

Self-Managed Nodes

Question # 6

Which OCI CLI command generates or merges the cluster configuration file required to authorize kubectl access to an OKE cluster?

A.

oci ce cluster update-kubeconfig

B.

oci ce cluster download-kubeconfig

C.

oci ce cluster create-kubeconfig

D.

oci ce cluster generate-kubeconfig

Question # 7

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?

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.

B.

Use Kubernetes HPA (Horizontal Pod Autoscaler) to scale the new version of the microservice to handle 10% of the traffic automatically.

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%.

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%.

Question # 8

Which statement accurately describes the Oracle Cloud Infrastructure (OCI) Load Balancer integration with OCI Container Engine for Kubernetes (OKE)?

A.

OKE service provisions an OCI Load Balancer instance for each Kubernetes service with LoadBalancer type in the YAML configuration.

B.

OKE service provisions a single OCI Load Balancer instance shared with all the Kubernetes services with LoadBalancer type in the YAML configuration.

C.

OCI Load Balancer instance provisioning is triggered by the OCI Events service for each Kubernetes service with LoadBalancer type in the YAML configuration.

D.

OCI Load Balancer instance must be manually provisioned for each Kubernetes service that requires traffic balancing.

Question # 9

When creating an alarm query in the OCI Monitoring service, which MQL trigger rule evaluates the lack of incoming raw metric data points as the trigger criteria?

A.

absence

B.

threshold

C.

missing

D.

non-zero

Question # 10
