Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
On the local ION device CLI only
Why it's wrong here
QoS should be managed globally via the controller for consistency.
- ✗
Inside the Prisma Access Security Policy
Why it's wrong here
Prisma Access handles security, not edge QoS queuing.
- ✓
On the Prisma SD-WAN Controller under Application QoS Policy
Why this is correct
The SD-WAN controller manages the traffic shaping and prioritization before it hits the WAN.
- ✗
Within the Cloud Identity Engine
Why it's wrong here
CIE is for identity, not traffic shaping.
