An administrator has configured a QoS policy rule and a QoS Profile that limits the maximum allowable bandwidth for the YouTube application. However, YouTube is consuming more than the maximum bandwidth allotment configured.
Which configuration step needs to be configured to enable QoS?
To enable QoS effectively on a network device, it is crucial to configure the QoS settings on the interface through which the traffic is flowing. By enabling QoS on the interface, the defined QoS policies and profiles can be applied to manage and control the bandwidth usage. Without enabling QoS on the interface, the configured QoS rules do not take effect, which explains why YouTube might be consuming more than the designated bandwidth. Therefore, the appropriate configuration step is to enable QoS on the interface.
QoS implementation on a Palo Alto Networks firewall begins with three primary configuration components that support a full QoS solution: a QoS policy, a QoS Profile, and configuration of the QoS egress interface. study guide page 225
aagreed on A: you cr4eate policy rule but still not being applied on the outbound/inbound interface
A is correct, and I agree with Daniel. This is confusing wording though, you don't enable a special QoS interface, you enable QoS [on an] interface.
This is exactly what threw me off with this question. I hate how exams seem to almost intentionally misword questions to trip folks up just to lower exam scores.
A You can find this answer in the PCNSE Study Guide (August 2020 version on page 257 ) study guide or the PAN-OS guide here Reference https://docs.paloaltonetworks.com/pan-os/10-0/pan-os-admin/quality-of-service/configure-qos.html

Weird wording but correct answer is A
