Prof. SaraJun 26, 2026The correct answer is D. Node Manager is a machine-scoped process, meaning a single Node Manager instance running on one machine can manage and start multiple Managed Servers that are also hosted on that same machine, which is a core architectural point the exam loves to test. Option A trips up a lot of students because Node Manager is domain-independent, it binds to a machine, not a domain, so you can use it across domains. Option C flips the concept entirely, since Node Manager cannot reach across to start servers on a different machine, each machine runs its own Node Manager instance, and option B is simply false because Node Manager absolutely can start the Admin Server using the nmStart() command or through the console.
Grace U.Jun 26, 2026D is the right pick, though option A trips a lot of people up because Node Manager does work within a domain context during configuration, which makes it feel true. The key distinction is that Node Manager itself is not bound to a single domain, and one instance on a machine can absolutely manage and start multiple Managed Servers that all live on that same machine.
Orla P.Jun 29, 2026The part worth adding is that Node Manager's domain independence is exactly why it survives an Admin Server crash and can still restart Managed Servers, which is the scenario where that distinction actually matters on the exam.
Orla P.Jun 26, 2026D is correct. One Node Manager instance covers the whole machine, so it can absolutely manage multiple Managed Servers sitting on that same box, which is probably the most common real-world setup you will see. The distractor in C is sneaky because Node Manager controls servers on its own machine only, not remote ones, so that one falls apart the moment you think about how the process actually runs.
Lena V.Jun 18, 2026Been drilling this topic all week for my recert and E is the one that keeps checking out for me, the whole point of Node Manager is that it manages one server instance per host at the process level, and the exam has consistently tested that boundary when I ran the practice sets. If you picked D you are confusing Node Manager scope with domain scope, which is a trap Oracle loves to set on this objective.
Orla P.Jun 19, 2026Lena, D is actually correct here. Node Manager is scoped to the machine level and manages server instances across multiple domains on that host, which is exactly the boundary Oracle tests on this objective.
Anjali D.Jun 26, 2026A is it, Node Manager ties directly to the domain.
Prof. SaraJun 29, 2026Anjali, Node Manager handles server lifecycle tasks like starting and stopping Managed Servers remotely, but it does not tie directly into the domain configuration itself, which is why D is the correct pick here. The domain is what defines the administrative boundary, and the option D reflects that relationship more accurately.
