Free NVIDIA NCP-AIO Actual Exam Questions - Question 15 Discussion

A. Draining the node puts it into a state where it finishes running jobs but doesn’t accept new ones, which seems like the safest first step before any real maintenance. Setting the node down (B/C) usually forces the node offline immediately, potentially killing jobs, so that feels a bit harsh if you can avoid it. D sounds like overkill—disabling scheduling on all nodes just because one needs maintenance doesn’t seem right. Better to isolate the node first by draining it.

Probably A. Draining prevents new jobs from starting but lets current ones finish gracefully, which seems safer before doing any maintenance. Setting it down (B or C) might be too harsh right away.

Draining seems like the logical first step to let current jobs finish without starting new ones, but does setting the state to down (B or C) also kick off an immediate stop on jobs? Wonder if that’s too abrupt.

Maybe B since setting node to down fully blocks scheduling and job starts, safer before maintenance.

It’s A, draining stops new jobs on that node without affecting others.

Setting the node state to down (B or C) right away isn’t ideal because it can interrupt running jobs, which is why draining first is key. Disabling scheduling on all nodes (D) seems way too broad for just one node’s maintenance and would impact the whole cluster unnecessarily. So, draining the specific node with scontrol update (A) makes sense since it lets current jobs wrap up cleanly before you take it offline.

It’s A. Draining the node stops new jobs but lets running ones finish, which makes way more sense than setting it down right away and risking job termination.

D imo, disabling job scheduling on all nodes seems way too broad for just one node’s maintenance. It’d unnecessarily halt jobs everywhere. Better to target the specific node, like with draining (A), so current jobs finish and no new ones start on that node only. That way, you keep the rest of the cluster running smoothly while you do your work.

A. Draining the node first lets current jobs finish while stopping new ones from starting, which avoids killing running work. Setting the node to down right away could mess up active jobs, so it’s better to start by draining. Also, disabling scheduling on all nodes (D) seems way too broad when only one node needs maintenance. So, A feels like the safest and most precise initial step here.

Option A makes sense since draining the node prevents new jobs from starting, which is safer before doing any maintenance. Setting it down first might interrupt running jobs unexpectedly.

Noticed B and C are identical, so they probably meant something else for one of them. But isn’t it safer to drain the node first so no new jobs get assigned before marking it down?

Why are options B and C the same? Is that a mistake?
