The cSRX is a containerized version of the SRX Series firewall that provides advanced security services, including content security, AppSecure, and unified threat management (UTM) in the form of a container1. The cSRX supports easy, flexible, and highly scalable deployment options covering various customer use cases, including application protection, microsegmentation, or as an edge gateway for secure IoT deployments through a Docker container management solution2. The cSRX also supports SDN via Contrail Enterprise Multicloud, OpenContrail, and other third-party solutions2. The cSRX also integrates with other next-generation cloud orchestration tools such as Kubernetes3.
The cSRX supports firewall, NAT, IPS, and UTM services, so option A is incorrect1. The cSRX does not only support Layer 2 “bump-in-the-wire” deployments, but also Layer 3 deployments with routing protocols such as BGP, OSPF, and IS-IS, so option B is correct4. The cSRX supports BGP, OSPF, and IS-IS routing services, so option C is correct4. The cSRX does not have three default zones, but instead inherits the zones from the host SRX Series device, so option D is incorrect5. References:
