• A. Direct TTL Probes
• B. Creating Custom Packets
• C. Anonymizers
• D. IP Address Decoy

Answer: (A)

This tests using a direct, simple check to see if a host is reachable. By sending a ping request to a legitimate host and waiting for a reply, you quickly verify that the host is up and can be communicated with. Using this approach with TTL-based probing gives a quick hint about how far away the host is (in terms of hops) and can reveal basic network presence without crafting special packets or disguising the source. It’s the straightforward option because it focuses on confirming reachability with a basic probe, whereas the other choices involve creating customized packets or masking the source, which isn’t about simply confirming that the host responds to a basic ping.
