What does the -sV flag do
starts a Version Scan
starts a Verbose scan
makes sure ports are verified
assigns a random value to each packet sent
starts a Version Scan
Which of the following is not true when discussing the -O flag
results will be 100% accurate
-O is a depreciated flag
root privileges are needed to use -O

results will be 100% accurate

What is the -T flag responsible for
controlling the speed of a scan
controlling the order of a scan
