PCNSE · Question #197
View the screenshots. A QoS profile and policy rules are configured as shown. Based on this information, which two statements are correct? (Choose two.)
The correct answer is A. DNS has a higher priority and more bandwidth than SSH. D. Facetime has a higher priority but lower bandwidth than Zoom. The QoS profile and policy rules, as depicted in the screenshots, define specific priorities and bandwidth allocations for different applications.

Why each option
The QoS profile and policy rules, as depicted in the screenshots, define specific priorities and bandwidth allocations for different applications.
Based on the configured QoS policy rules, DNS traffic is assigned a higher priority and allocated more bandwidth compared to SSH.
The implied QoS configuration does not indicate that Google-video has both higher priority and more bandwidth than WebEx.
SMTP, typically a non-real-time application, is not assigned higher priority than Zoom, which usually receives higher priority for real-time communication.
The configured QoS policy grants Facetime a higher priority over Zoom, while Zoom is allocated a larger share of bandwidth.
