SNMP has evolved over time into the SNMPv2 and then lastly with the SNMPv3. SNMP provided a minimal but powerful set of facilities for monitoring and control of network elements using a straightforward Structure of Management Information (SMI), MIB, and protocol. But as there are more requirements for monitoring and as networks became more complex, new versions of the SNMP are released.

Compare and contrast the three versions of SNMP, explaining the deficiencies which the preceding version had, which paved the way for the newer version to be created.

Explain in detail two or more strengths of each new version and what it has been brought to today's marketplace.

Discuss in detail two or more advances of SNMPv3 in its security engine and any new MIBs.
