A network administrator needs to provide daily network usage reports on all layer 3 devices without
compromising any data while gathering the information. Which of the following would be configured to
provide these reports?

A.
SNMP

B.
SNMPv3

C.
ICMP

D.
SSH

Explanation:
Currently, SNMP is predominantly used for monitoring and performance management. SNMPv3 defines a
secure version of SNMP and also facilitates remote configuration of the SNMP entities.
Incorrect Answers:
A: You can use SNMP to interact with several network devices to acquire status information, performance
data, statistics, and configuration details via a management console.
C: ICMP is a protocol that is commonly used by tools such as ping, traceroute, and pathping.
D: SSH transmits both authentication traffic and data in a secured encrypted form. Thus, no information is
exchanged in clear text. This makes SSH a secure alternative to Telnet, which transmits both
authentication credentials and data in clear text.
