Explanation

Note: The question asks for two correct answers, but only one (B) is listed as correct. Based on data center best practices, B and C are the intended correct pair. The explanation below covers both.

Proper cable management (B) directly improves maintenance by keeping cables organized, labeled, and accessible, which reduces troubleshooting time and the risk of accidentally disconnecting the wrong cable during servicing. Split rear doors (C) allow technicians to access the back of rack-mounted equipment without fully swinging open a heavy door into another rack or obstruction, making it physically easier to service components.

Underfloor cabling (A) can actually hinder serviceability because cables routed beneath raised floors are difficult to trace, inspect, and modify without disrupting airflow management or lifting floor tiles. Unique enclosures (D) have the opposite effect of what is needed: non-standard, one-off designs require specialized knowledge and tools, which increases complexity and slows down maintenance rather than simplifying it.

Memory tip: Think "standardize and organize." Anything that makes cabling cleaner (cable management) or physical access easier (split doors) helps technicians work faster. Anything that hides cables or introduces custom, non-repeatable designs works against you.
