Explanation: There are five elements of VACM model. They are: (I) groups, (2) security level (3) contexts, (4) MIB views and view families, and (5) access policy. An SNMP context is a collection of management information accessible by an SNMP entity. An SNMP entity has access to potentially more than one context. Each SNMP engine has a context table that lists the locally available contexts by contextName.
