8. Which of them do not comes under NETBIOS information?
a) Name of the system / PC
b) Workgroup name
c) MAC address
d) RAM space
View Answer
Explanation: Scanning using IP address simply pings each IP address for checking if it is live or not. This helps in providing NETBIOS information such as the name of the system, workgroup and MAC address.
9. A ______________ is a simple network scanning technique used for determining which range of IP address map to live hosts.
a) scan sweep
b) ping sweep
c) scan ping
d) host ping
View Answer
Explanation: A ping sweep is a simple network scanning technique used for determining which range of IP address map to live hosts. The ping sweep consists of ICMP ECHO requests.
