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

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?

AOutbound (TCP)

BBi-directional (TCP)

CBi-directional (ICMP)

DOutbound (ICMP)

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.

Kimberlie 5 months ago

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

Elke 6 months ago

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

Sabrina 6 months ago

I think it should be Bi-directional (TCP).

Chun 6 months ago

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

Roselle 6 months ago

Bi-directional TCP seems more secure, right?

Felicitas 6 months ago

Wait, why would we need ICMP for this?

Yaeko 6 months ago

I agree, outbound TCP is the way to go!

Raina 7 months ago

Definitely need outbound TCP for those ports.

Larae 7 months ago

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.

Maybelle 7 months ago

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

Mozelle 8 months ago

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

Lindsey 8 months ago

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

Kerry 8 months ago

Definitely B. Bi-directional (TCP) is the way to go for disaster recovery communication.

Lashaunda 8 months ago

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

Clorinda 8 months ago

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

Dan 8 months ago

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

Gary 9 months ago

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

Shannan 9 months ago

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.

Bernardo 9 months ago

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.

Santos 9 months ago

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.

Jovita 9 months ago

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.

Loren 10 months ago

I think I know the answer to this one. We need to open up those ports for disaster recovery, so the rule-type should be Bi-directional (TCP).

Mozelle 3 months ago

↳ replying to Loren

Right, without it, disaster recovery won't work properly.

Alba 4 months ago

↳ replying to Loren

Definitely, we need that two-way communication.

Crista 5 months ago

↳ replying to Loren

I agree, Bi-directional (TCP) makes sense for those ports.
