A penetration tester writes the following script: Which of the following objectives is the tester attempting to achieve?

The correct answer is A. Determine active hosts on the network. Although the script itself is not rendered in the question text, the correct answer indicates this is a host-discovery script-commonly a ping sweep, ICMP echo loop, or ARP scan iterating over a range of IP addresses to identify which hosts are online.

Explanation

Although the script itself is not rendered in the question text, the correct answer indicates this is a host-discovery script-commonly a ping sweep, ICMP echo loop, or ARP scan iterating over a range of IP addresses to identify which hosts are online. Such scripts typically iterate through a subnet (e.g., 192.168.1.1–254), send a probe (ICMP, TCP, or ARP), and report back which addresses respond. This is a standard reconnaissance technique for mapping live hosts before deeper enumeration. The other options (TTL manipulation, ARP table flooding, port scanning) describe different objectives.
