An administrator implements a security policy that references a custom application matching UDP port 5000. When reviewing active traffic, packets on UDP port 5000 are being dropped even though a policy permits the custom application. Upon further inspection, you find that Junos AppID has classified the traffic as 'unknown-udp'. Why is the policy not matching?

When configuring a zone-based security policy in Junos, what is the default action applied to any traffic that does not match any explicitly defined security policy rules?

You are troubleshooting a connectivity issue where traffic between two custom zones is being blocked despite a policy permitting it. Upon reviewing the security policies using the CLI command 'show security policies', you notice that an earlier policy with broader match criteria is catching the traffic and applying a deny action. What security policy concept is causing this behavior?

An administrator configures a security policy on a SRX Series device with the action set to 'count'. What is the primary function of this action in Junos security policies?
