Which database stores information about network elements managed by the SNMP protocol in a complex network?

• A. Management Information Base (MIB)
• B. Log file
• C. Local backup
• D. Local

Answer: (A)

SNMP uses a Management Information Base as the information store for all data that can be managed on network devices. The MIB is a structured, tree-like database of objects—things like interface status, bandwidth counters, CPU load, and device uptime—that defines what data can be queried or configured by SNMP. Each device ships with MIB definitions, and the SNMP manager uses these definitions to interpret responses and interact with the device in a consistent way across a complex network. This standardized data model is what makes centralized monitoring and management possible. A log file simply records events after they happen, a local backup is a copy of data for recovery, and “local” doesn’t refer to the structured data store SNMP relies on.
