AppQoS (Application Quality of Service) is a Junos OS feature that provides advanced control and prioritization of application traffic. With AppQoS, you can classify application traffic, assign a forwarding class to the traffic, and apply quality of service (QoS) policies to the traffic. You can also re-write DSCP values and reserve bandwidth for important applications. However, AppQoS does not re-write the TTL or rate-limit traffic.

Static attack object groups are predefined groups of attack objects that are included in Juniper's IPS signature database. These groups do not change automatically when Juniper updates the database.

The two statements that are correct about the cSRX are that it supports firewall, NAT, IPS, and UTM services, and that it has three default zones: trust, untrust, and management. The cSRX is a software- defined security solution that provides comprehensive network security capabilities and is designed for virtualized environments. It supports firewall, NAT, IPS, and UTM services to protect against threats, as well as BGP, OSPF, and IS-IS routing services for routing functionality.
Additionally, the cSRX has three default zones: trust, untrust, and management. The trust zone is used to define traffic that is allowed to enter the network, the untrust zone is used to define traffic that should be blocked from entering the network, and the management zone is used to manage the device itself. The cSRX does not support Layer 2 "bump-in-the-wire" deployments.
