NetApp Exam NS0-593 Topic 8 Question 27 Discussion

Actual exam question for NetApp's NS0-593 exam

Question #: 27
Topic #: 8

After expanding a two-node AFF A300 cluster with two AFF A700 nodes, you observe latencies when data is accessed indirectly. The system node run -node -command netstat command shows retransmits and packet drops on the LIFs. The AFF A700 nodes with 40 Gbps and the AFF A300 connect with 10 Gbps to the cluster interconnect. You are using Cisco Nexus 3132Q cluster interconnect switches. You just updated to ONTAP 9.8 software.

In this scenario, what is causing this problem?

AThe 10 Gbps to 10 Gbps cluster Interconnect is creating a speed mismatch.

BAFF A300 and AFF A700 node mixing Is not supported in ONTAP 9.8 software.

CThe AFF A300 Is using an adapter card for the cluster Interconnect, but only onboard ports are supported.

DThere is an NXOS firmware mismatch, verify in the Interoperability Matrix (1MTJ for a supported version.

Aw, man, they must have forgotten to check the Interoperability Matrix. Classic ONTAP move right there. At least they updated to 9.8, though...that's something, I guess.

Firmware mismatch, eh? That's always a pain to troubleshoot. Gotta love it when the cluster interconnect switches don't play nice.

Firmware mismatches can be tricky to resolve, especially with cluster interconnect switches.

Hmm, the adapter card issue could definitely be the culprit here. Looks like they didn't do their homework on the supported configurations.

I believe we should also check for any NXOS firmware mismatch as mentioned in the Interoperability Matrix.

I agree with Johnna, the 10 Gbps to 10 Gbps cluster Interconnect could be causing the problem.

I think the issue might be with the cluster Interconnect speed mismatch.

Mixing node models is never a good idea, especially with a major version upgrade like 9.8. This is probably the root cause of the problem.

The speed mismatch between the AFF A300 and AFF A700 nodes is definitely causing the latency issues. I'm surprised they didn't catch that during the expansion.
