1Z0-997-26 Cloud Native Architecture Practice Question
Your organization wants to deploy an ephemeral, event-driven data processing task that runs for less than 3 minutes whenever a new object is uploaded to an OCI Object Storage bucket. Which serverless combination is the most cost-effective and operationally efficient solution?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure an OCI Events rule to trigger an OCI Function upon object creation in Object Storage.
OCI Events service can listen to Object Storage bucket creation events and directly trigger an OCI Function without requiring dedicated virtual machines to run continuously.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use an OCI Database with PL/SQL triggers to download files from Object Storage.
Why it's wrong here
Databases are not designed for direct binary object ingestion processing workflows via triggers in this manner.
- ✓
Configure an OCI Events rule to trigger an OCI Function upon object creation in Object Storage.
Why this is correct
This native serverless pattern requires zero server management and incurs costs only when the function executes.
- ✗
Deploy a Kubernetes deployment with 10 replicas on an OKE cluster to monitor bucket logs.
Why it's wrong here
Running continuous pods for intermittent object creation events is overly complex and resource-inefficient.
- ✗
Provision an Always Free Compute VM running a cron job that polls Object Storage every minute.
Why it's wrong here
Polling introduces latency and requires continuous server management, violating optimal cloud-native event-driven design.
