Nokia Certified Network Associate (NCNA) — Question 46

Which of the following describes the Nokia 7750 SR Input/Output Module (IOM)?

Answer options

• A. Small optical module available in a variety of formats.
• B. Contains a CPU for managing the forwarding hardware in each flexible fast path.
• C. Converts traffic from an external standard format to an internal format.
• D. Contains the CPU that runs the routing protocol software as well as the switch fabric.

Correct answer: B

Explanation

Option B is correct because the Nokia 7750 SR IOM indeed contains a CPU that manages the forwarding hardware in the flexible fast path. Options A, C, and D describe different functionalities that do not accurately represent the primary role of the IOM, which is focused on forwarding management rather than optical formats or traffic conversion.
