The exhibit provides information about an SRX Series device operating in transparent mode (Layer 2) and Layer 3 routing at the same time. Let’s break down the correct answers:
Explanation of Answer B (Secure Inter-VLAN Traffic with a Security Policy):
The SRX device can secure inter-VLAN traffic because it supports security policies for Layer 3 traffic between different VLANs. In this case, traffic moving between different VLANs (i.e., Layer 3 traffic) can be processed and controlled using security policies.
Explanation of Answer C (Pass Layer 2 and Layer 3 Traffic Simultaneously):
The SRX device can handle both Layer 2 and Layer 3 traffic simultaneously. In mixed mode, the device is capable of switching traffic at Layer 2 (intra-VLAN) while also routing traffic at Layer 3 (inter-VLAN). This is evident from the global configuration showing transparent bridge mode and Layer 3 interfaces.
Juniper Security Reference:
Mixed Mode Overview: Juniper SRX devices in mixed mode can operate as both a Layer 2 switch and a Layer 3 router, allowing it to pass traffic at both layers simultaneously. Reference: Juniper Mixed Mode Documentation.
