According to the Juniper Networks official JNCIA-SEC Exam Guide, web filtering is a feature used to control access to web content, including the ability to block specific types of files.

Junos-host and null are two non-configurable zones that exist by default on an SRX Series device. Junos-host is the default zone for all internal interfaces and services, such as management and other loopback interfaces. The null zone is used to accept all traffic that is not explicitly accepted by other security policies, and is the default zone for all unclassified traffic. Both zones cannot be modified or deleted.

Only static NAT with pool ensures both traffic initiated from inside and outside networks use the same IP address.

Global policies are used to define rules for traffic that is not associated with any particular zone. This type of policy is evaluated first, before any rules related to specific zones are evaluated.

For more detailed information about global policies, refer to the Juniper Networks Security Policy Overview guide, which can be found at https://www.juniper.net/documentation/en_US/junos/topics/reference/security-policy-overview.html. The guide provides an overview of the Juniper Networks security policy architecture, as well as detailed descriptions of the different types of policies and how they are evaluated.
