Regarding MIB, which of the following descriptions is incorrect?

Question

Options

• AThe full name of MIB is Management Information Base
• BOID in MIB is usually marked with a set of letters
• CMIB is an important part of SNMP network management model
• DThe MIB information of the device can be read through the MIB BROWSER tool.

• A
  3% (1)
• B
  83% (25)
• C
  3% (1)
• D
  10% (3)

Explanation

Option B is incorrect because OIDs (Object Identifiers) in MIB are represented as a sequence of numbers separated by dots (e.g., 1.3.6.1.2.1.1.1.0), not letters. Each number in the sequence identifies a specific node in the MIB tree hierarchy.

Options A, C, and D are all accurate: MIB does stand for Management Information Base (A), it is a foundational component of the SNMP (Simple Network Management Protocol) management architecture (C), and tools like MIB Browser are standard utilities used to query and read MIB data from network devices (D).

Memory tip: Think of an OID like a postal address made entirely of numbers - each digit narrows down the location in the MIB tree. Letters would be ambiguous and non-standard in this numeric hierarchy. If you remember "OID = numeric dotted notation," option B's use of "letters" will immediately stand out as wrong on any exam.
