1Z0-997-26 Cloud Native Architecture Practice Question
Which TWO of the following are key architectural benefits of adopting serverless OCI Functions compared to managing traditional container clusters for event-driven tasks?
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
✓
Automatic scaling from zero to thousands of executions based on incoming events without managing servers
OCI Functions provide automatic scaling down to zero and relieve operators from managing underlying infrastructure/servers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Built-in requirement to configure manual Kubernetes Horizontal Pod Autoscalers
Why it's wrong here
Incorrect. Functions do not use Kubernetes HPA.
- ✗
Guaranteed permanent container warm-start memory caching with zero cold starts ever
Why it's wrong here
Incorrect. Cold starts can still occur when scaling from zero or after prolonged inactivity.
- ✗
Full administrative root access to the underlying hypervisor and host operating system kernel
Why it's wrong here
Incorrect. Serverless functions are fully managed by Oracle; users do not have hypervisor or host OS access.
- ✓
Automatic scaling from zero to thousands of executions based on incoming events without managing servers
Why this is correct
Correct. Serverless functions scale automatically and require no server management.
- ✓
Pay-as-you-go pricing model where you only pay for the exact execution time consumed down to the millisecond
Why this is correct
Correct. OCI Functions bill based on invocation count and execution duration.
