The network management functional model defined by OSI is divided into multiple functional areas. Which of the following does not belong to this functional area?

Question

Options

• AData management
• BPerformance Management
• CFault Management
• DConfiguration management

• A
  73% (16)
• B
  14% (3)
• C
  9% (2)
• D
  5% (1)

Explanation

Data Management (A) is correct because it is not part of the OSI Network Management functional model. The OSI model defines exactly five functional areas, remembered by the acronym FCAPS: Fault Management, Configuration Management, Accounting Management, Performance Management, and Security Management.

The distractors (B, C, D) are wrong because Performance Management, Fault Management, and Configuration Management are all genuine FCAPS pillars - Fault Management detects and isolates network failures, Configuration Management tracks and controls network device settings, and Performance Management monitors throughput, latency, and utilization metrics.

Memory tip: Use the acronym FCAPS (pronounced "ef-caps") - Fault, Configuration, Accounting, Performance, Security. Any answer that falls outside these five is the odd one out, and "Data Management" simply doesn't appear in this standard.
