NetApp NS0-593 Exam - Topic 2 Question 77 Discussion

Actual exam question for NetApp's NS0-593 exam

Question #: 77
Topic #: 2

Your customer complains that u host will constantly report losing a connection to the iSCSl target and then report that the session was reestablished.

As shown in the exhibit, what is a cause of this flapping?

AA host with an IP address of 172.20.10.80 and a second host with an IP address of 10.10.20.60 have the same IQN.

BA host with an IP address of 172.20.10.80 and a second host with an IP address of 10.10.20.60 are in different initiator groups.

CA host with an IP address of 172.20.10.80 and a second host with an IP address of 10.10.20.60 are accessing the same LUN.

DA host with an IP address of 172.20.10.80 and a second IP address of 10.10.20.60 is accessing different LUNs.

Show Suggested Answer

Suggested Answer: A

IQN stands for iSCSI Qualified Name, which is a unique identifier for an iSCSI initiator or target1.

ONTAP uses IQN to authenticate and authorize iSCSI sessions2.

If two hosts have the same IQN, they will cause a conflict and ONTAP will reject the new session request from the second host3.

This will result in the host losing the connection to the iSCSI target and then reporting that the session was reestablished, as shown in the exhibit.

To avoid this problem, each host should have a unique IQN.Reference:

True, but I feel A is more direct. Conflicts are usually the root cause.

But what about C? Accessing the same LUN could also cause issues.

I disagree, it could just be a network hiccup, right?

Definitely a problem with the same IQN, no doubt about it.

Wait, are they really in different initiator groups? That seems odd.

I think it's more about the LUN access.

Sounds like a classic IQN conflict issue.

I'm going with B. Gotta keep those initiator groups in check, am I right?

Haha, I bet the customer's iSCSI target is just having a bad day. Happens to the best of us!

Hmm, I'm going with B. Initiator groups seem like the most likely culprit here.

D is the correct answer. Accessing different LUNs should not cause the connection to flap.

I think C is the correct answer. Accessing the same LUN can definitely cause connection issues.

B is the correct answer. Having hosts in different initiator groups can cause the connection to flap.

I’m not convinced about option D since accessing different LUNs shouldn’t cause flapping, right? It feels like it’s more about the connection stability.

Accessing the same LUN could definitely cause issues, so I’m leaning towards option C, but I need to double-check that.

I think I saw a similar question where initiator groups were involved. Maybe option B is relevant here too?

I remember something about IQNs causing conflicts, so option A might be the right answer, but I'm not completely sure.

Okay, I've got a strategy here. The key is to focus on the details in the exhibit and see which answer choice best matches what's shown. I think I can work this out.

This flapping issue is tricky. I think it's A. Same IQN causes conflicts.

Ugh, iSCSI questions are the worst. I'm just going to read through the choices carefully and try to eliminate the ones that don't make sense based on the information provided.

D doesn't seem right. Different LUNs shouldn't cause flapping like this.

Alright, let's do this. I'm feeling pretty confident about my iSCSI knowledge, so I'm just going to read through the choices and pick the one that seems most plausible.

Hmm, the exhibit shows two different IP addresses, so I'm thinking it might have to do with the hosts being in different initiator groups. I'll need to double-check that against the answer choices.

This looks like a tricky iSCSI question. I'll need to carefully review the exhibit and the answer choices to figure out the most likely cause of the connection flapping.
