According to the Official CompTIA PenTest+ Self-Paced Study Guide1, the correct answer is A. nmap -sn -n
-exclude 10.1.1.15 10.1.1.0/24 -oA target_txt.
This command will perform a ping scan (-sn) without reverse DNS resolution (-n) on the IP range 10.1.1.0/24, excluding the attack machine's IP address (10.1.1.15) from the scan (-exclude). It will also output the results in three formats (normal, grepable and XML) with a base name of target_txt (-oA).
