NetApp NS0-593 Exam - Topic 7 Question 42 Discussion

Actual exam question for NetApp's NS0-593 exam
Question #: 42
Topic #: 7
[All NS0-593 Questions]

A storage administrator reports that a monitoring toot is reporting that the storage controller reads between 90% to 93% CPU use. You run the sysstat -m command against the node in question.

Referring to the exhibit, which statement is correct?

Show Suggested Answer Hide Answer
Suggested Answer: B

Here is my reasoning:

Thesystem node hardware unified-connect showcommand displays the status and configuration of the Unified Connect ports on a node1. This command can help you identify if the ports are configured correctly and if they have any errors or faults.

The ports 0e and 0f on the AFF A300 are 10GbE ports that support both Ethernet and Fibre Channel over Ethernet (FCoE) protocols2.These ports are part of the Unified Connect feature, which enables you to use the same physical port for different protocols without requiring additional hardware3.

If the ports are offline, it could indicate a problem with the port configuration, the cable connection, the switch configuration, or the protocol settings.Thesystem node hardware unified-connect showcommand can help you troubleshoot these issues by showing you the port mode, speed, duplex, state, and error count1.

The other commands in the options are not as helpful for troubleshooting the port issue, because they show different information that is not related to the Unified Connect feature or the port status. For example:

Thevserver fcp wwpn-alias showcommand displays the World Wide Port Name (WWPN) aliases for the Fibre Channel Protocol (FCP) logical interfaces (LIFs) on a Vserver4. This command can help you manage the FCP LIFs, but it does not show the status of the physical ports or the Unified Connect feature.

Thestorage port showcommand displays the status and configuration of the storage ports on a node5. This command can help you manage the storage ports, but it does not show the status of the Unified Connect ports or the FCoE protocol.

Thevserver fcp interface showcommand displays the status and configuration of the FCP LIFs on a Vserver6. This command can help you manage the FCP LIFs, but it does not show the status of the physical ports or the Unified Connect feature.

Here are some references that might help you:

I feel like option C makes the most sense. If CPU usage is that high, we should definitely gather more data and possibly escalate it.

Isn't the IS_Service critical too? It seems like it could be related to multicast settings, but I'm confused about the exact linkage here.

Okay, let's break this down. The question says the Data Confidentiality pattern is applied to all services, which means encryption is required. So the answer must be True.
