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.

For threat remediation in a third-party network, the RADIUS protocol is necessary to communicate with the RADIUS server for details about infected hosts. CoA enables security measures to be enforced based on endpoint information provided by the RADIUS server. Details on this setup can be found in Juniper RADIUS and AAA Documentation.
When deploying threat remediation to endpoints connected through third-party devices, such as switches, the following conditions must be met for proper integration and functioning:
* Explanation of Answer A (Support for AAA/RADIUS and Dynamic Authorization Extensions):
* Third-party switches must support AAA (Authentication, Authorization, and Accounting) and RADIUS with Dynamic Authorization Extensions. These extensions allow dynamic updates to be made to a session's authorization parameters, which are essential for enforcing access control based on threat detection.
* Explanation of Answer B (Connector Gathers MAC Information via API):
* The connector uses an API to gather MAC address information from the RADIUS server. This MAC address data is necessary to identify and take action on infected hosts or endpoints.
* Explanation of Answer D (Connector Initiates CoA):
* The connector queries the RADIUS server for infected host details and triggers a Change of Authorization (CoA) for the infected host. The CoA allows the connector to dynamically alter the host's access permissions or isolate the infected host based on its threat status.
Juniper Security Reference:
* Threat Remediation via RADIUS: Dynamic remediation actions, such as CoA, can be taken based on information received from the RADIUS server regarding infected hosts. Reference: Juniper RADIUS and CoA Documentation.
