Security policies in Junos OS match traffic based on specific criteria:
Source and destination addresses(Option B).
Application(Option D), which may be defined as services (e.g., tcp/80) or recognized through AppID.
Other options:
MAC addresses(Option A) are not used in policy matching; policies operate at Layer 3/4.
Interface name(Option C) is used in firewall filters, not in security policy definitions.
Correct Criteria:Source address and Applications
