200-150 Question #113: Real Exam Question with Answer & Explanation

Question

Options

• AThe switch has just been powered on, and the module is resetting.
• BThe module is resetting and both ejector levers are out.
• CThe module has been inserted during the initialization process.
• DThe module could not power up because of insufficient power.
• EThe operator has activated this LED to identify this module in the chassis.

Explanation

A flashing blue LED on a Cisco Nexus 7000 I/O module means the operator has enabled the beacon locator function to physically identify that module in the chassis.

Common mistakes.

• A. A module that is resetting after initial power-on displays an amber or cycling status LED pattern, not a blue beacon light, which is reserved for the operator locator function.
• B. Ejector levers being in the out position during a reset triggers a physical seating alert, not the blue beacon LED, which cannot be activated by mechanical conditions.
• C. A module inserted during the chassis initialization process shows an initialization or amber status LED, not a flashing blue light, because blue is assigned exclusively to the operator-activated beacon function.
• D. Insufficient power to bring up a module causes the LED to show amber or remain off to indicate a power fault condition, which is a separate LED state from the blue beacon.
