Question 610
At the Ivystone health services network, during an infrastructure audit, users access a prohibited remote-control application over ports normally permitted for web browsing. Which interpretation best explains what is happening?
Explanation
Correct Answer
Application identification can distinguish software traffic that shares common transport ports. This directly explains the reported condition at the Ivystone health services network; it supports the decision to use Application Control to restrict the identified application rather than relying on port matching alone.
Incorrect Answers

At the Ivystone health services network, however, the reported facts indicate that application identification can distinguish software traffic that shares common transport ports.
That statement describes unified access rule: application Control and URL Filtering work with Access Control policy; rule order and matching still matter. At the Ivystone health services network, however, the reported facts indicate that application identification can distinguish software traffic that shares common transport ports.
That statement describes custom url list: a custom URL entry provides a targeted control independent of broader category assignment.
