Redundant 110v power
Answers
D.
Redundant 110v power
Suggested answer: C

Explanation:

In the preparation for a new cluster installation, after ensuring that the basic physical requirements such as space, cabling, and hardware connectivity are met, it's crucial to confirm power requirements. For enterprise installations, particularly where high-powered equipment like a four-node cluster is involved, ensuring redundant power is critical. The question specifically mentions 'redundant' power, suggesting the need for a high-capacity solution typically found in 208v configurations in data centers, which provides more power efficiently and is standard for high-density computing hardware. Therefore, redundant 208v power should be confirmed as available onsite to support the new cluster's power needs effectively.
