SK0-003 · Question #459

When planning for redundant power sources in a server deployment, which of the following should be purchased? (Select TWO).

The correct answer is B. Multiple UPSs E. Redundant power supplies. To ensure redundant power sources for a server deployment, multiple Uninterruptible Power Supplies (UPSs) and redundant power supplies within the servers themselves should be purchased.

Why each option

To ensure redundant power sources for a server deployment, multiple Uninterruptible Power Supplies (UPSs) and redundant power supplies within the servers themselves should be purchased.

ARAID controllers

RAID controllers manage hard drive arrays for data redundancy and performance, but they do not provide power redundancy.

BMultiple UPSsCorrect

Multiple UPSs (Uninterruptible Power Supplies) provide battery backup power, protecting servers from power outages and fluctuations, with multiple units adding redundancy at the infrastructure level.

CRedundant cooling

Redundant cooling systems protect against overheating, which is a different aspect of environmental redundancy than power.

DDual NICs

Dual NICs (Network Interface Cards) provide network redundancy and load balancing, not power redundancy.

ERedundant power suppliesCorrect

Redundant power supplies within a server mean that the server has two or more power supply units, where if one fails, the others automatically take over, ensuring continuous server operation.
