SmartQoS can prioritize critical applications by limiting resources allocated to non-critical applications.

• A. True
• B. False
• C. It expands resources for all apps
• D. Requires dedicated hardware

Answer: (A)

SmartQoS works by enforcing service levels for different workloads. It does this by setting limits and quotas on resources like bandwidth or IOPS for less important (non-critical) applications. When those non-critical apps are restricted, the remaining capacity can be allocated to the critical applications, helping them meet required response times and throughput. That is why the statement is true: prioritization is achieved by throttling or limiting non-critical workloads so critical ones get the resources they need.

Note that total resources aren’t magically increased; the system reallocates what’s already available. Also, dedicated hardware isn’t a strict requirement—SmartQoS can be implemented in software on existing storage controllers, though hardware support can sometimes enhance performance.
