   A company is considering using Secure Wire on its SRX device to provide transparent security for a critical application. The application uses non-IP protocols that the security team wants to inspect. What is a limitation of Secure Wire that the team should consider?

   • ASecure Wire can inspect non-IP protocols if the interfaces are in different security zones.
   • BSecure Wire can inspect non-IP protocols but requires additional configuration of custom applications.
   • CSecure Wire requires the use of VLAN tagging to inspect non-IP protocols.
   • DSecure Wire only supports IP-based traffic; non-IP protocols are not processed by security policies.

   What happens to traffic that arrives on one Secure Wire interface and is destined for a host on the other interface?

   • AIt is dropped because Secure Wire does not allow traffic between interfaces
   • BIt is routed based on the destination IP address
   • CIt is encapsulated and sent to a central controller for inspection
   • DIt is inspected by security policies and then forwarded out the other interface

   An administrator is troubleshooting a Secure Wire deployment where traffic is not being forwarded. The administrator has verified that the interfaces are up, in the same zone, and the security policy is correct. The administrator also notices that the device is receiving traffic on the Secure Wire interfaces but not forwarding it. What should the administrator check next?

   • ACheck the MAC address table to see if the device is learning MAC addresses correctly.
   • BCheck the routing table to see if a route exists for the destination.
   • CCheck the ARP table to see if the device has resolved the destination IP address.
   • DCheck the security policy to see if it is configured for the correct zone.

   A network administrator has configured Secure Wire on an SRX device. The device is receiving traffic on interface ge-0/0/0 and forwarding it out ge-0/0/1. The administrator notices that the traffic is being processed by the security policies, but the source and destination MAC addresses are being preserved. What is the expected behavior of Secure Wire in this scenario?

   • AThe device rewrites the source MAC address to its own MAC address.
   • BThe device encapsulates the traffic in a tunnel and forwards it to the next hop.
   • CThe device rewrites the destination MAC address to the next-hop router's MAC address.
   • DThe device acts as a transparent bridge, forwarding frames without modifying the MAC addresses.
