NetApp Certified Data Administrator (NCDA) – E-Series — Question 57

An administrator notices that the applications are running slowly. The administrator wants to determine which component on the ONTAP subsystem is experiencing the most latency.
In this scenario, which command would you use to accomplish this task?

Answer options

• A. run -node * stats show system::sys_avg_latency
• B. statistics system show
• C. run -node * -command sysstat -x 1
• D. qos statistics latency show

Correct answer: D

Explanation

The command 'qos statistics latency show' (D) is specifically designed to display latency statistics related to the Quality of Service (QoS) of the ONTAP subsystem, making it the right choice. The other options, while related to system statistics, do not focus directly on latency measurements, which is the primary requirement in this scenario.
