Which test identifies which addresses are in use by sending probe packets to all addresses in the target range?

• A. Network Sweeping
• B. Network Tracing
• C. NeXCSer Tool
• D. Network Services Test

Answer: (D)

Identifying which addresses are in use by sending probe packets across the entire target range is a network sweep, commonly called a ping sweep. This technique quickly reveals live hosts by showing which addresses respond to probes, giving you a map of active devices to target for further enumeration. It’s not about mapping routes between networks (that’s network tracing) and it’s not about testing which services are running on hosts (that would come after you know the hosts). So the scenario matches a network sweep.
