Juniper JN0-335 Dumps Questions Answers

The vSRX is a virtual firewall that offers the same features as the physical SRX Series firewalls, but in a virtualized form factor. It supports next-generation firewall (NGFW) capabilities, networking, and automated lifecycle management. It also integrates with cloud orchestration tools and software-defined networking (SDN) solutions1

The vSRX supports VMXNET3 vNICs, which are optimized for performance in virtualized environments. VMXNET3 vNICs offer enhanced networking features such as jumbo frames, hardware offloads, and multicast filtering2

The vSRX runs on Linux as the base OS, which provides a stable and secure platform for the Junos OS and the firewall functionality. Linux also enables the vSRX to leverage the native hypervisor drivers and APIs for better performance and compatibility3

The fab interface is a physical connection between two nodes of a chassis cluster that is used to forward traffic and synchronize session state between the nodes. The fab interface can be any pair of Ethernet interfaces on the same LAN, but they must be the same media type. You need to specify the physical interfaces to be used for the fab link in the configuration, as the system does not determine them automatically. The Junos OS supports only one fab link per node, and it does not support traditional interface features such as IP addressing, routing protocols, or firewall filters. The fab interface is assigned an internally derived IP address by the system for packet transmission. Thefab link also does not support fragmentation, so the MTU size of the fab interface must be equal to or greater than the MTU size of the largest interface in the cluster. References:

= The vSRX is a virtual firewall that offers the same features as the physical SRX Series firewalls, but in a virtualized form factor for delivering security services that scale to match network demand. The vSRX supports Juniper Contrail Networking and third-party software-defined networking (SDN) solutions, which enable dynamic and automated network provisioning and management. The vSRX also integrates with cloud orchestration tools such as OpenStack, which allow for flexible deployment and configuration of virtual machines and networks. The vSRX provides granular security for the workloads that run within the virtual network on the public or private cloud. It supports next-generation firewall capabilities, such as application security, intrusion prevention, user identity, and role-based access control. It also supports advanced threat prevention features, such as malware sandboxing, threat intelligence feeds, and encrypted traffic inspection. The vSRX can protect the network from both internal and external threats, and enforce consistent security policies across the entire network. References:
