Which MX7000 component is responsible for Fabric Consistency Check?

Question

Options

• AManagement Module
• BLifecycle Controller
• CFabric Switching Engine
• DiDRAC

• A
  89% (49)
• B
  5% (3)
• C
  4% (2)
• D
  2% (1)

Explanation

Option A is correct because the Management Module (MM) is the central intelligence of the MX7000 chassis, responsible for chassis-wide orchestration including the Fabric Consistency Check - a process that validates fabric configurations across all compute sleds and I/O modules to ensure they are consistent and properly aligned.

Why the distractors are wrong:

• B. Lifecycle Controller handles firmware lifecycle tasks (updates, deployment, OS provisioning) on individual servers - it has no role in chassis fabric validation.
• C. Fabric Switching Engine performs the actual data-plane switching work; it executes fabric operations but doesn't govern consistency policy or validation.
• D. iDRAC manages an individual sled's hardware (power, sensors, remote console) and has no visibility into chassis-wide fabric topology.

Memory tip: Think "MM = Master Manager." Just as a building manager ensures all floors (sleds) follow the same rules, the Management Module ensures all fabric configurations are consistent - it's the chassis-level authority, not any individual component.
