Answer 1

Solution for the problem is provided below, please comment if any doubts:

Structure of Management Information (SMI):

• SMI can be described as a model that is used to define the information that is created by the in Simple Network Management Protocol or SNMP.
• The SMI consist of three parts, one is to define the independent modules, the second one is to define the objects and last one is to define notifications.
• The SMI provides the basic hierarchy of the management data, but it tell less about the objects that needs to be managed. The SMI is constructed as a framework and their building blocks are managed objects.

Useful for managed objects since:

• The concept of SNMP is the definition of object identifiers.
• The managed objects can be allocated in a tree fashion based on the allocated object identifiers in SMI.
• There hierarchical tree structure of managed objects make it traverse friendly since it need to traverse from root to leaves to achieve each objects, the path conflicts to attain an object can be avoided using SMI.
