Discuss Exin CDCS Exam Topic 2 Question 13

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.

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.

Victor 10 months ago

Wait, are we really saying loose cables are safer?

Maryann 10 months ago

Cables should be loose to prevent damage during quakes.

Melissia 10 months ago

I totally agree, flexibility is key!

Samira 11 months ago

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

Ahmed 11 months ago

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.

Pamela 11 months ago

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.

Zena 11 months ago

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?

Alpha 12 months ago

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

Anthony 12 months ago

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.

Eun 12 months ago

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.

Cordelia 1 year ago

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.

Lelia 1 year ago

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.

Ronny 1 year ago

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.

B) I see, safety first in a seismic-prone area.

↳ replying to Carma

A) It's a trade-off for ensuring they don't get damaged during an earthquake.

↳ replying to Carma

B) But wouldn't loosely organized cables make it harder to troubleshoot and maintain?

A) Cables should be loosely organized to allow for movement and be latched at the connectors.

Romana 2 years ago

Haha, replace them with busbar trunking? That's like replacing your car with a rocketship for the daily commute. B is the obvious choice here.

User 2: Yeah, cables need to be tightly organized in a seismic-prone area.

↳ replying to Romana

User 1: Haha, I agree! B is definitely the way to go.

Micaela 2 years ago

That's a good point, Xochitl. Safety should be the top priority in a seismic-prone area.

Xochitl 2 years ago

I disagree, I believe option B is the way to go. Tight organization will prevent cables from becoming a hazard.

Jesusita 2 years ago

Definitely not C - that's just asking for trouble in a seismic-prone area! Gotta keep those cables organized and secure.

Micaela 2 years ago

I think option A is the best choice. Loose organization allows for movement during an earthquake.

Diane 2 years ago

Option A seems like the way to go. We want to allow for some movement to prevent damage during seismic activity, but also secure the connections.
