Which characteristic is associated with an effective scan solution?

• A. Be platform dependent
• B. Be disruptive
• C. Perform host discovery
• D. Perform buffer overflow exploits

Answer: (C)

An effective scan solution starts by identifying which machines are actually present on the network. This host discovery step reveals live targets so you can focus vulnerability checks where there are systems to assess, making scans faster, more accurate, and more efficient. Without discovering hosts, you’d waste time scanning dead addresses and might miss active systems. In the PCI context, a good scanner should also be non-disruptive and not attempt exploits during a standard scan, which is why other characteristics like being disruptive or performing buffer overflow exploits aren’t appropriate. Platform dependence is undesirable because you want broad compatibility across environments. So, the ability to perform host discovery is the best fit.
