Question # 1



You have deployed automated threat mitigation using Security Director with Policy Enforcer, Juniper ATP Cloud, SRX Series devices, Forescout, and third-party switches. In this scenario, which device is responsible for communicating directly to the third-party switches when infected hosts need to be blocked?
A. Forescout
B. Policy Enforcer
C. Juniper ATP Cloud
D. SRX Series device



B.
  Policy Enforcer

Explanation:

Policy Enforcer receives these policies and translates them into device-specific commands. It then communicates with the third-party switches (using protocols like SNMP, RADIUS, or vendor-specific APIs) to enforce those commands, such as blocking the infected hosts' MAC addresses or port access.

Why Policy Enforcer is the Right Choice:

Centralized Enforcement: Policy Enforcer acts as the central point of enforcement for Security Director policies, ensuring consistent security across the network.

Multi-Vendor Support: It can interact with a wide range of network devices, including switches from different vendors.

Automation: Policy Enforcer automates the policy enforcement process, enabling rapid response to threats.

Explanation:

In active/passive HA, dynamic routing protocols run only on the primary (active) node.

[Reference:, "In a chassis cluster, the primary node handles all control plane tasks, including dynamic routing.", Source: Juniper TechLibrary - Chassis Cluster Overview, Option C: Physical connections are used for the control and fabric links., Explanation:, Control and fabric links are direct physical connections between cluster nodes., Reference:, "The control and fabric links must be connected using physical interfaces between the nodes.", Source: Juniper TechLibrary - Chassis Cluster Components, Why Options B and D are Incorrect:, Option B: Dynamic routing is not active on both devices simultaneously in active/passive mode., Option D: The Inter-Cluster Link (ICL) uses Layer 2 connectivity, not Layer 3., Conclusion:, The correct options are A and C., ]
