Question

Which two characteristics describe a null zone?

Choose two

A The null zone is configured by the super user.
B By default, all unassigned interfaces are placed in the null zone.
C All ingress and egress traffic on an interface in a null zone is permitted.
D When an interface is deleted from a zone, it is assigned back to the null zone.

Explanation

On Juniper SRX devices, interfaces are in the null zone by default and cannot pass traffic until they are assigned to a security zone. Removing an interface from a security zone leaves it unassigned, so it returns to the null zone.
