Exin CDCS Exam - Topic 2 Question 13 Discussion

Actual exam question for Exin's CDCS exam

Question #: 13
Topic #: 2

What precaution shall be taken for cabling leading into an equipment rack when a data center is in a seismic-prone area?

ACables should be loosely organized to allow for movement and be latched at the connectors.

BCables shall be tightly organized to the rack and trays to avoid movement.

CCables can be organized in any way as it is not important.

DCables should be replaced by busbar trunking.

Show Suggested Answer

Suggested Answer: D

Design changes during the implementation phase are generally allowed only when there is a strong business and/or technical justification. Changes at this stage can lead to delays, increased costs, or compromise design integrity. Thus, a rigorous assessment is required to ensure any modifications are essential and provide clear benefits or address critical issues.

Detailed Explanation:

Changes post-design freeze should be minimized to avoid scope creep and additional costs. However, if a technical issue arises that would affect operational goals, or a business need warrants modification, justified changes are permissible, following an impact assessment and approval process.

EPI Data Center Specialist References:

EPI project management guidelines recommend a controlled change management process during implementation, allowing changes only when they align with critical objectives or address unforeseen issues that affect the project's success.

Tightly organized sounds better to me.

Wait, are we really saying loose cables are safer?

Cables should be loose to prevent damage during quakes.

Busbar trunking? That's a new one for me!

I don’t recall much about busbar trunking being a standard solution for this, so D feels off to me. I’m leaning towards A as well.

I practiced a question similar to this, and I think it emphasized the importance of securing cables without restricting movement. So, A seems like the best choice.

I’m not entirely sure, but I feel like tightly organizing cables could actually create more issues during a quake. Maybe B is too strict?

I remember something about needing to allow for movement in seismic areas, so I think A might be right.

I think the key is to avoid any rigid or fixed cabling that could be damaged during a seismic event. Loose organization with latched connectors seems like the safest option to me.

Wait, I'm confused. Shouldn't the cables be tightly organized to the rack and trays to avoid movement? Or is that not the right approach here? I need to think this through a bit more.

Okay, I've got this. The cables need to be loosely organized to allow for movement, but also latched at the connectors to prevent disconnection. That's the best way to protect the equipment in a seismic-prone area.

Hmm, I'm not totally sure about this one. I know we need to take precautions for seismic activity, but I'm not sure if tightly organizing the cables or replacing them with busbar trunking is the right approach.

This question seems pretty straightforward. I think the key is to allow the cables to have some flexibility to accommodate movement during a seismic event.

Loosely organized cables that are latched at the connectors? Sounds like a recipe for a cable management nightmare, but I guess it's better than having them rip out of the rack during an earthquake.
