Juniper JN0-335 Exam With Confidence Using Practice Dumps

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:

• [SRX] Behavior of active sessions when modifying a security policy1

 The error occurred because the “http” application is not defined in this context of Juniper SRX Series device configuration. One solution is to create a custom application named “http” at the [edit applications] hierarchy level (Option C). Another solution is to modify the security policy to use the built-in “junos-http” application which is predefined and doesn’t need an explicit definition (Option D). Options A and B are not correct because they do not address the root cause of the error, which is the undefined application “http”. References: The answers can be verified from Juniper’s official documentation on security policies and applications available on their website.
