Comprehensive Detailed Step-by-Step Explanation with All Juniper Security Reference
Understanding Secure Wire:
Secure Wire Feature:
Connects two interfaces directly without any Layer 2 or Layer 3 processing.
No routing or switching lookup occurs.
Use Case:
Ideal for scenarios where traffic needs to pass through the SRX device transparently.
Option B: Secure wire
Secure wire creates a bidirectional link between two interfaces.
Traffic flows between the interfaces as if they are connected by a physical wire.
Reference:
"The secure wire feature allows traffic to pass between two interfaces without any security
processing or route lookups."

Why Other Options Are Incorrect:
Option A: Transparent mode involves Layer 2 switching.
Option C: Mixed mode combines Layer 2 and Layer 3 but doesn't prevent switching/routing lookups.
Option D: Switching mode operates at Layer 2 and includes switching lookups.
Conclusion:
Secure wire is the correct feature to map two interfaces together without switching or routing
lookups.
