In a Junos logical system, where can a security profile be applied?

To security policies and interfaces

Only to interfaces, not to security policies

Only to the root logical system

To routing instances and VPN tunnels

An administrator configures a security profile with a screen option to block oversized ICMP packets. The profile is applied to a policy in a tenant system. During testing, oversized ICMP packets are still passing through. The screen logs show no alerts. What is the most likely cause?

The screen option is not enabled in the security profile; it is only defined but not activated.

The security profile is applied to the wrong policy, so it is not inspecting the ICMP traffic.

The default security profile is overriding the custom profile's screen options.

The tenant system does not support ICMP screen options.

An administrator configures a security profile with screen options to protect against IP spoofing and a custom ALG for SIP traffic. After deployment, users report that SIP calls are failing, and the screen logs show no spoofing alerts. The profile is applied to the relevant policy. What is the most likely cause of the SIP failure?

The SIP ALG is not enabled in the security profile, so the custom ALG settings are ignored.

The security profile is applied to the wrong interface, so it is not affecting the SIP traffic.

The screen options are blocking SIP packets as spoofed traffic.

The SIP ALG requires a separate security policy to function, which is missing.

Which command would you use to verify that a security profile is correctly applied to a security policy?
