Which of the following modules is not a functional module of the MA5600 SCU main control board?

Question

Options

• ACPU module
• BEthernet switch module
• CClock module
• DSeparator module

• A
  2% (1)
• B
  17% (8)
• C
  7% (3)
• D
  74% (34)

Explanation

Option D (Separator module) is correct because no such functional module exists within the MA5600 SCU main control board architecture. "Separator" refers to a physical/mechanical component used to divide or isolate hardware elements, not a logical or functional board module.

• A (CPU module) is a real SCU component - it handles system control, protocol processing, and management plane operations.
• B (Ethernet switch module) is a real SCU component - it provides internal switching fabric and uplink connectivity between board subsystems.
• C (Clock module) is a real SCU component - it generates and distributes synchronization signals to keep all board functions timed correctly.

Memory tip: The three real modules all perform active system functions (process, switch, synchronize). "Separator" is a passive mechanical concept - if a choice sounds like something that divides space rather than performs a function, it's the odd one out.
