Which term best matches the following definition: Unique identifier for objects in SNMP management.

• A. Object Identifier (OID)
• B. Domain Definition Table (DDT)
• C. User Provisioning
• D. Delegated Administration

Answer: (A)

In SNMP management, unique identifiers for each data point are Object Identifiers, or OIDs. They form a hierarchical tree in the MIB, so every object—like system name, status, or counters—has a distinct place and a unique numeric address. OIDs are written as dotted-decimal strings (for example, 1.3.6.1.2.1.1.5 for sysName), ensuring that managers and agents reference the exact object without ambiguity. The other terms don’t fit SNMP’s naming system: a Domain Definition Table isn’t a standard SNMP concept, User Provisioning relates to managing user accounts, and Delegated Administration concerns who manages resources rather than how objects are identified. Therefore, the term that best matches the definition is Object Identifier (OID).
