A fleet garage must mark popular SaaS applications for QoS even when clients use ephemeral destination ports. Which approach recognizes those applications beyond static port ACLs?
Select an answer to reveal the explanation.
Short Explanation
SaaS apps hop ports like delivery vans changing lanes. NBAR reads the application fingerprint so you can mark the right traffic without memorizing every ephemeral port. Pair it with MQC and your QoS policy stays honest.
Full Explanation
NBAR (and related application recognition) identifies applications using deeper signatures than well-known ports, which is essential when SaaS uses TLS and dynamic ports. Classification results feed MQC marking and queuing. Port-only ACLs miss many cloud apps; disabling CEF or null-shaping are not classification strategies.
