The correct answer is A.
OBJ-3.2: SNMP provides a lot of information about different target devices on the network. Based on the output shown, you should identify that this is an SNMP scan based on the “community string” keyword. From your Network+ and Security+ studies, you should remember that SNMP uses community strings as a basic authentication mechanism before allowing you to access a network device’s statistics. In this scan, two devices are found on this network with default public and private community strings. This makes these devices vulnerable to an SNMP attack for further exploitation.
