Nutanix NCP-DB Exam - Topic 4 Question 39 Discussion

Actual exam question for Nutanix's NCP-DB exam

Question #: 39
Topic #: 4

Which port should be opened to ensure the NDB server, NDB agent, and NDB database agent can communicate with the registered cluster via REST API calls?

A2009

B3205

C3260

D9440

Show Suggested Answer

Suggested Answer: A

To ensure the NDB server, NDB agent, and NDB database agent can communicate with the registered cluster via REST API calls, port 2009 must be opened. This port is used by NDB components to facilitate RESTful communication with the Nutanix cluster (e.g., Prism Element or Prism Central) for operations such as provisioning, monitoring, and management. Proper firewall configuration to allow traffic on this port is a prerequisite for NDB's integration with the cluster.

Other options are incorrect:

B . 3205: Not a standard NDB port; used for other Nutanix services.

C . 3260: Associated with iSCSI, not REST API communication.

D . 9440: Used for Prism Element's HTTPS management interface, not NDB-specific REST calls.

Thus, the verified answer is A, reflecting NDB's REST API requirements.

Definitely port 9440 for NDB communication.

B) 3205 is also incorrect. That's the port for the NDB data nodes, not the REST API.

C) 3260 is the wrong port. That's used for the NDB management server, not the REST API.

A) 2009 is the wrong answer. That's the port used for the NDB web interface, not the REST API.

I remember discussing port 3260 in class, but I don't think that's the right one for the NDB server. It might be 9440 instead.

I’m a bit confused; I thought it might be 2009, but I can't recall the exact details from my notes.

I think the port for NDB communication is 9440, but I'm not entirely sure. I remember something about REST APIs needing specific ports.

Ah yes, I remember learning about that in class. Port 9440 is the one that allows the NDB components to talk to each other over the REST interface. I'll go with D) 9440.

Based on my understanding, the REST API for NDB typically uses port 9440. I'm pretty confident that's the right answer here.

I'm a bit confused on the different components here. I'll need to review my notes on NDB architecture to figure out which port is used for the REST API.

D) 9440 is the correct answer. The NDB server, NDB agent, and NDB database agent use port 9440 to communicate with the registered cluster via REST API calls.

I practiced a similar question, and I believe it's 3205. It seems to be the common port for database agents.

Okay, let me see if I can break this down. The NDB server, agent, and database agent all need to communicate via REST API, so the key is finding the right port for that.
