Server Noise Diagnosis: Fan Replacement vs Remote Access
Short answer
D Replace the fans.
Question
Key Takeaways
The exam tests the ability to distinguish between symptoms requiring immediate physical intervention (noisy fans) versus those requiring diagnostic data, while avoiding unnecessary service disruptions like remote sessions when the cause is obvious.
This SK0-005 question tests the priority of physical hardware maintenance over remote diagnostics when servers are noisy but operational. The community consensus and official answer favor replacing fans as the immediate corrective action for loud noises without error indicators.
Common mistake: Candidates often choose C (Establish a remote connection) because they prioritize gathering logs before acting, failing to recognize that loud noise from multiple servers indicates an imminent hardware failure (fans) that requires physical replacement to prevent downtime.
Expert Analysis
Why the Answer Is Correct
Replacing the fans (Option D) is the correct first step because loud noises in servers typically indicate cooling system issues, specifically failing or obstructed fans. Since the servers are still working correctly and no indicator lights are showing errors, this suggests the components have not yet failed completely but are degrading. Immediate physical replacement prevents potential overheating and subsequent unplanned downtime, aligning with best practices for proactive maintenance.
Why the Other Options Are Wrong
Option C (Establish a remote connection) is incorrect because it introduces unnecessary delay; if the technician is already on-site and hears loud noises, checking logs remotely does not fix the physical issue causing the noise. Option A (Replace the drives) is wrong because drive failures usually present with distinct SMART errors or indicator lights, not just general loud noise. Option B (Upgrade firmware) is irrelevant to mechanical noise issues and could potentially introduce instability during the process.
Community Comment Notes
Comment [1] strongly supports D, noting that without indicator lights, the issue is likely pre-failure fan degradation rather than a complete crash. It also highlights that since the tech is local, setting up a remote connection is redundant. Comment [2] argues for C based on monitoring multiple racks, but this overlooks the urgency of preventing hardware failure. Comment [3] suggests C allows for preliminary assessment, but in certification scenarios, 'loud noise' is a classic keyword for fan replacement.
Exam Strategy
When troubleshooting hardware, always prioritize physical safety and immediate risk mitigation. If a symptom like 'loud noise' points directly to a common mechanical failure (like fans), and the system is still running, plan for physical replacement rather than time-consuming remote diagnostics.

[Removed] 👍 2 Answered DGiven that there are no indicator lights, it means that nothing actually failed. The most likely reason of the noise are failing fans that just haven't completely failed yet. Secondly, the tech is local, there's literally no reason to establish a remote connection. If he really want to check some logs, he'd use a cart. Lastly, what else makes loud noises on a server?? The answer is clearly D

surfuganda 👍 1 Answered CC. Establish a remote connection to the server. This approach enables the technician to perform a preliminary assessment and potentially pinpoint the cause of the noise without immediately resorting to physical interventions that may disrupt server operations. Once the source of the noise is identified through logs or hardware status reports, the technician can decide on the appropriate course of action, whether it involves replacing specific components or adjusting configurations to mitigate the noise.

ompk 👍 1Assuming several servers in different racks are noisy, so in order to monitor them, the technician may establish the remote connections to all of them instead of changing fans. But who chooses the answers in a public community thread, this is questionable
