NetApp Exam NS0-593 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:

Anybody else picturing the storage admin frantically googling 'how to fix 90% CPU usage' while downing their third cup of coffee? Just me? Okay, then.

Hold up, 'high network exempt use'? Is that like when the network gets a free pass to hog all the resources? Sounds like a recipe for trouble to me.

Option D? Really? Clearly, the person who wrote that answer has never actually worked with ONTAP. CPU usage is kind of a big deal, you know.

I agree, CPU usage is definitely an important metric to monitor in ONTAP.

I'd say option C is the way to go - better gather some data and get the experts involved before this turns into a full-blown disaster.

But shouldn't we also advise the customer to exclude certain workflows to reduce CPU use?
