Juniper JN0-231 Exam With Confidence Using Practice Dumps

User-defined security zones allow users to configure multiple security zones and share them between routing instances. This allows users to easily manage multiple security zones and their associated policies. For example, a user can create a security zone for corporate traffic, a security zone for guest traffic, and a security zone for public traffic, and then configure policies to control the flow of traffic between each of these security zones. Transit traffic can also be managed using user-defined security zones, as the policies applied to these zones will be applied to the transit traffic as well.

The correct statement about Junos security policies is that they enforce rules that should be applied to traffic transiting an SRX Series device. Security policies control the flow of traffic between different zones on the SRX Series device, and dictate which traffic is allowed or denied. They can also specify which application and service requests are allowed or blocked. More information about Junos security policies can be found in the Juniper Networks technical documentation here:

"Service objects represent applications and services that can be assigned to a security policy rule. Applications and services can either be predefined by Junos software or custom defined by the administrator."
