2.5 implement cybersecurity resilience

Question 1

RAID 0

Answer 1

striping only
high performance, no redundancy

Question 2

RAID 1

Answer 2

mirroring
duplicates data
requires 2 disks

Question 3

RAID 5

Answer 3

striping with parity
fault tolerant,
requires only one extra disk for redudancy

Question 4

RAID 10

Answer 4

Striping and mirrors
combines RAID 0 and 1 for maximum speed and redundancy

Requires 4 disks and only 50% can be storage

Question 5

Incremental file backup

Answer 5

backs up the files from each day seperately
requires all days for restoration

Question 6

differential file backup

Answer 6

each day stacks up
requires only last day for restoration

Question 7

NAS

Answer 7

network attached storage
connects to shared storage across network

Question 8

SAN

Answer 8

a network of storage devices that can be accessed by multiple servers or computers, providing a shared pool of storage space. Each computer on the network can access storage on the SAN as though they were local disks connected directly to the computer.

Question 9

Multipath disk redundancy

Answer 9

providing failover for data storage systems

It uses redundant physical path components, such as cables, switches, and adapters, to connect a server to storage

Question 10

Snapshot

Answer 10

quick backup method, can only be on the same disk as the data.
