Oracle Cloud Infrastructure Developer Professional Sample Questions:

Question 1

Your team has deployed a high-throughput order processing microservice that consumes messages from an OCI Stream with 8 partitions. To handle peak operational hours, you have scaled out your deployment to run
12 identical microservice consumer instances under a single named consumer group. During execution, you notice that 4 of the 12 consumer instances remain completely idle and are not assigned any stream data.
Which OCI Streaming architectural rule explains this behavior?

A. The instances are idling because you must configure OCI Service Connector Hub to explicitly map each of the 12 consumer instances to its own partition.
B. The instances are idling because OCI Streaming requires a dedicated stream pool for every four active consumer instances in a consumer group.
C. The instances are idling because each partition in a stream can be consumed by at most one consumer instance within a single consumer group.
D. The instances are idling because a single consumer group cannot support more than 8 active consumer instances regardless of partition count.

Question 5

Your development team wants to configure API Gateway request validation to shield an upstream backend microservice from ill-formed API calls.

Which TWO configurations should you apply to your API Gateway deployment specification to meet this requirement?

A. Configure the request validation policy with header validations to mandate the presence of the required HTTP header.
B. Set the request validation policy mode to Enforcing to forward failed requests to the execution log instead of blocking them.
C. Set the request validation policy mode to Permissive to log validation failures without rejecting requests.
