Q: 5
As a cloud engineer, you are responsible for managing a Kubernetes cluster on the Oracle Cloud
Infrastructure (OCI) platform for your organization. You are looking for ways to ensure reliable
operations of Kubernetes at scale while minimizing the operational overhead of managing the
worker node infrastructure.
Which cluster option is the best fit for your requirement?

I don't think it's A. B's the better choice here since OCI OKE virtual nodes take out all the worker node management completely, not just reduce it. Managed nodes (A) still leave you patching or monitoring VMs sometimes. Pretty sure B matches what Oracle wants but open to other opinions if I missed something.
Option B. Serverless virtual nodes mean zero node admin overhead, so matches the question.
I don't think it's B, I'd actually pick A here. Managed nodes plus cluster autoscalers really minimize most infra overhead, and you still get more control than with virtual nodes. Trap is thinking only 'serverless' counts as low-op, but managed pools are nearly hands off these days. Pretty sure, but maybe I'm missing a nuance.
What if they asked about maximizing control instead of minimizing overhead? Wouldn't A or even D then flip to be the better fit since you'd want more direct access to worker nodes? The answer really depends on whether they're prioritizing zero management (B) or hands-on config.
Its B here, not A. A is tricky since managed nodes reduce overhead a lot but you still have to patch them sometimes. With virtual nodes (B), Oracle handles all node stuff behind the scenes. I’ve seen similar questions worded like this in practice sets too, and they go with B for zero worker management. Disagree?
Its B
B tbh, since with virtual nodes on OKE you don't mess with any worker node infra at all. That takes the operational overhead basically to zero, which matches what the question wants. Managed nodes (A) still need a bit of admin. Open if anyone has a better angle.
B , since virtual nodes mean you don't touch worker node infra at all-literally no patching or upgrades to deal with. Managed nodes (A) still need some upkeep, so not fully hands-off. Pretty sure but open to other takes.
B
B is the pick since OCI OKE virtual nodes mean you don't deal with any worker node infra-true serverless. I saw official docs and labs make a big deal of this when minimizing operational overhead is key. Pretty confident, but let me know if anyone's seen an exception on practice tests.
Be respectful. No spam.
