Which type of messages received by nodes with a suspected strangler attached are accepted and processed to the called station?

• A. Flash
• B. Strangler
• C. Propagation
• D. Transmission

Answer: (A)

The main idea is how signaling control is handled when a node might be compromised by a strangler device. A Flash signal is a momentary off-hook indication that the network recognizes as a legitimate user-initiated control to access features or to route the call toward the called station. Because it’s a clear, purpose-driven control signal, the system accepts it and processes it to the called station even in the presence of a suspected strangler. The other message types do not serve this direct control function and could be tied to data, propagation, or attacker behavior, so they aren’t forwarded to complete the call.
