200-150 Question #247: Real Exam Question with Answer & Explanation

The correct answer is B: There are four WWNNs. NOTE: The marked answers (B and C) appear to conflict with standard Fibre Channel definitions. In FC, a World Wide Node Name (WWNN) identifies a node - typically one per physical HBA. A server with two physical HBAs should have exactly two WWNNs (making option E correct, not B).

Question

Which two descriptions of the WWNNs on a server that has two physical HBAs are true? (Choose two.)

Options

AEach WWNN is globally unique
BThere are four WWNNs
CEach WWNN is locally unique
DAll WWNNs are identical
EThere are two WWNNs.

Explanation

NOTE: The marked answers (B and C) appear to conflict with standard Fibre Channel definitions. In FC, a World Wide Node Name (WWNN) identifies a node - typically one per physical HBA. A server with two physical HBAs should have exactly two WWNNs (making option E correct, not B). Additionally, WWNNs are globally unique - the 'WW' in World Wide Node Name explicitly means globally unique across all SAN fabrics (making option A correct, not C). 'Locally unique' (option C) and 'four WWNNs' (option B) contradict standard FC naming conventions. The technically correct answers should be A (globally unique) and E (two WWNNs).
