Dell EMC Specialist – Systems Administrator, Unity XT — Question 16

A Dell EMC Unity storage administrator has 10 hosts. One of the hosts experiences occasional, huge IO bursts.
What is a best practice for avoiding performance issues during these burst periods?

Answer options

• A. Enabling Quality of Service (QoS) will limit the burst problem
• B. Quality of Service (QoS) is enabled by default, so one only needs to configure burst settings
• C. Enable Quality of Service (QoS) then limit I/O for the entire FC port
• D. Enable Quality of Service (QoS) then configure burst settings

Correct answer: D

Explanation

The correct answer is D because enabling Quality of Service (QoS) allows for specific configurations to manage I/O during high-demand periods effectively. Options A and C do not provide the necessary granularity for managing bursts, while option B incorrectly assumes QoS requires no additional configuration for burst handling.
