We begin part 2 of Operations Security module by looking at fault management, the practice of managing faults within your environment and what components are involved in that. For example, you'll learn about Spares, RAID, Shadowing and you'll also see now this directly ties into Business Continuity. We'll discuss the difference between hot, warm and cold swappable devices and what that means security preparedness thru redundancy. And finally for Part 2 of Operations Security, we really dissect, clarity and explore the functions of RAID. In exploring RAID Arrays 0, 1, & 5, you'll learn which is NOT redundant or fault tolerant, why that's important, and where you'd find a non-fault tolerant RAID Array in use.
