Which network proximity approach is described to speed up large scans?

• A. Increase the number of timeouts
• B. Move machines closer to the target network
• C. Use encrypted connections to speed scan
• D. Reduce the number of scanners

Answer: (B)

Lowering the distance between the scanners and the targets reduces network latency, so probes and responses travel fewer hops and arrive faster. In large scans, the time spent waiting for replies often dominates, and shortening RTT lets you send more probes in parallel and complete the sweep more quickly. Placing scanning machines closer to the target network—or within the same data path—directly speeds up the overall process.

Other options don’t achieve that speedup. Increasing timeouts just makes the scanner wait longer for slow responses, slowing progress overall. Encrypting connections adds cryptographic overhead without inherently making scans faster. Reducing the number of scanners decreases coverage and prolongs the total time needed to complete the scan.
