Nutanix NCP-CI-Azure Exam - Topic 1 Question 20 Discussion

Actual exam question for Nutanix's NCP-CI-Azure exam
Question #: 20
Topic #: 1
[All NCP-CI-Azure Questions]

An administrator needs to open the following ports in the firewall between an on-premises cluster and azure for disaster recovery:

* 22

* 2009

* 2020

* 2049

* 3260

* 9440

Which rile-type should be created on the firewall for communication to be appropriately established?

Show Suggested Answer Hide Answer
Suggested Answer: B

Port Requirements: The specified ports (22, 2009, 2020, 2049, 3260, 9440) are commonly used for various services and require TCP communication.

Port 22: SSH

Port 2009: Used for Nutanix internal communication

Port 2020: Nutanix services

Port 2049: NFS

Port 3260: iSCSI

Port 9440: Nutanix Prism management

Communication Type: To ensure proper disaster recovery setup, bi-directional communication is needed to allow traffic to flow both from on-premises to Azure and vice versa.

TCP Protocol: These ports use the TCP protocol, which provides reliable communication between devices.

Conclusion: Creating a bi-directional (TCP) rule on the firewall allows the necessary communication for disaster recovery processes.

Bi-directional (ICMP) is not suitable here. We need TCP for those ports.

Outbound (TCP) could work, but not ideal for this.

Yeah, that makes sense. We need two-way communication.

Are we sure all those ports are necessary? Seems like a lot!

Wait, why would we need ICMP for this?

Haha, I bet the person who wrote this question was just trying to trick us. B is the only logical answer, no doubt about it.

B is the obvious choice here. Who wants to be stuck with just outbound or ICMP when you need full TCP control?

Hmm, I was thinking C. Bi-directional (ICMP) would be better for pinging the ports. But I guess B makes more sense.

I agree, B is the correct answer. Gotta keep those ports open both ways for the data to flow.

I’m leaning towards outbound TCP, but I wonder if there are exceptions for certain ports that might require bi-directional.

I feel like bi-directional makes sense since we need communication both ways, but I can't recall the specifics.

I think we had a practice question about opening ports for Azure, and it was definitely TCP.

I remember studying firewall rules, but I'm not entirely sure if it should be bi-directional or just outbound.

I'm not entirely sure about this one. I'm leaning towards D) Outbound (ICMP), but I'm not 100% certain. Maybe I should review the question again and think about the specific requirements for disaster recovery.

I'm pretty confident that the answer is B) Bi-directional (TCP). We need to allow two-way communication between the on-premises cluster and Azure for disaster recovery, so a bi-directional rule makes the most sense.

Okay, let me think this through. We need to open those specific ports, so the rule-type should be Outbound (TCP). That way, the traffic can flow out from the on-premises cluster to Azure.

Hmm, I'm a bit confused. Do we need to open up ICMP ports as well, or just TCP? I'm not sure if the question is asking for a mix of protocols or just one.
