Oracle Cloud Infrastructure Developer Professional Sample Questions:
Question 1
Your organization is transitioning a monolithic billing system into a cloud-native microservices application deployed on Oracle Cloud Infrastructure Container Engine for Kubernetes. To maintain high operational excellence under the observability pillar of cloud-native development, the engineering team has successfully set up centralized log aggregation and system metrics. However, you must now implement a solution that can track, visualize, and analyze end-to-end transaction flows and asynchronous call hops across multiple distributed microservices.
Which service should be integrated to fulfill this distributed transaction tracing requirement?
A. OCI Logging Analytics
B. OCI Application Performance Monitoring
C. OCI Service Mesh
D. OCI Monitoring
Question 2
Which statement accurately describes the Oracle Cloud Infrastructure (OCI) Load Balancer integration with OCI Container Engine for Kubernetes (OKE)?
A. OCI Load Balancer instance provisioning is triggered by the OCI Events service 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 must be manually provisioned for each Kubernetes service that requires traffic balancing.
D. OKE service provisions an OCI Load Balancer instance for each Kubernetes service with LoadBalancer type in the YAML configuration.
Question 3
Your development team has deployed a fleet of web application servers across three fault domains in a specific compartment in OCI. To simplify operational dashboards, you must construct a single Monitoring Query Language (MQL) expression that calculates the average CPU utilization for each individual fault domain, rather than plotting each server individually. The expression must output exactly three lines, one for each fault domain, on the resulting Metrics Explorer chart.
Which MQL expression correctly fulfills these requirements?
A. CpuUtilization[1m].split(faultDomain).mean()
B. CpuUtilization[1m].filter(faultDomain).mean()
C. CpuUtilization[1m].groupBy(faultDomain).mean()
D. CpuUtilization[1m].grouping().mean()
Question 4
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.)
A. 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 '
B. Set up the following dynamic group for your function ' s OCID: Name: read-file-dg Rule: resource.id =
" ocid1.fnfunc.oc1.phx.aaaaaaaakeaobctakezjz5i4ujj7g25q7sx5m vr55pms6f4da '
C. 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 '
D. No policies are needed. By default, every function has read access to Object Storage buckets in the tenancy.
E. 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 '
Question 5
Your Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) administrator has created an OKE cluster with one node pool in a public subnet. You have been asked to provide a log file from one of the nodes for troubleshooting purpose. Which step should you take to obtain the log file?
A. It is impossible because OKE is a managed Kubernetes service.
B. SSH into the node using the public key.
C. SSH into the nodes using the private key.
D. Use the username opc and password to login.
