What is the benefit of a unified storage system in terms of cost reduction?
Answer(s): A
A unified storage system consolidates file and block storage into a single platform, reducing the need for multiple, separate storage systems and thus lowering acquisition, management, and operational costs.
You have a RAID 6 array with four 250 GB disks.What is the total usable data storage capacity in this scenario?
Answer(s): B
RAID 6 uses two disks' worth of capacity for dual parity. With four 250 GB disks (total 1000 GB), the usable capacity is 1000 GB 500 GB (parity) = 500 GB.
Which RAID level provides the highest write I/O performance?
RAID 1+0 (also written as RAID 10) provides the highest write I/O performance among these options because it combines striping and mirroring, allowing for parallel write operations with no parity overhead.
