Free NVIDIA NCP-AIO Actual Exam Questions - Question 13 Discussion

Question No. 13
You are setting up a Kubernetes cluster on NVIDIA DGX systems using BCM, and you need to initialize
the control-plane nodes.
What is the most important step to take before initializing these nodes?
Select one option, then reveal solution.

Option D is important because each control-plane node needs a unique external IP to communicate properly and be reachable by other nodes and components. Without that, the cluster setup could fail or behave unpredictably. This step is often overlooked but critical before running kubeadm init, especially in multi-node setups.

Disabling swap (B) is definitely key, but another crucial step is making sure each control-plane node has a proper network setup so they can communicate correctly. Without proper IP configuration or connectivity, the initialization can run into errors. So while B is important, I think D also matters because external IPs help with node discovery and cluster communication during init. The load balancer (A) usually comes after at least one control-plane is up, and Docker (C) is needed but not as critical as ensuring the nodes don’t have swap enabled first.

B/C? Disabling swap is definitely critical, but Docker also needs to be up and running before you start. Without the container runtime ready, init might not go smoothly.

B imo, disabling swap is a strict kubeadm requirement to avoid runtime issues. Other steps matter later, but swap off is the first must-do across all control-plane nodes.

It’s B, swap must be off to ensure kubeadm init doesn't fail.

Yeah, without disabling swap first, kubelet won’t start properly. B

Makes sense that disabling swap (B) is key since Kubernetes won’t start properly if swap is on. Even if Docker (C) is important, Kubernetes can’t initialize control-plane nodes without that swap off first. The load balancer (A) and external IPs (D) usually come later for multi-node setups. So I’d stick with B as the essential first step before any init.

B. Disabling swap is a must for kubelet to function properly during init.

B. Swap has to be off because Kubernetes won’t even start the control plane components otherwise. Setting up Docker or IPs comes after that, so disabling swap is the real blocker here.

B/C? Docker is critical for running containers, so it has to be up and running before initialization. But disabling swap is a stricter requirement since kubelet refuses to start if swap’s enabled, so B edges it out.

Swap definitely causes kubelet to fail, so disabling it on all control-plane nodes makes sense before starting anything. I’d go with B here.

Guessing B is key because swap messes with kubelet and cluster stability right from the start. Without disabling swap, Kubernetes won’t even initialize properly.

Maybe B, since Kubernetes won’t start properly if swap isn’t off, and that’s a requirement on every control-plane node, not just the first one.

B/C? Disabling swap is critical for Kubernetes to work properly, but Docker being installed and running is also essential since it's the container runtime. Can't skip either before init.

B, but are we sure swap must be disabled on ALL control-plane nodes or just the one being initialized first?
