RAID 10

a combination of RaID 1 and RaID 0 that requires at least four disks to work as an array of drives and provides the best redundancy and performance.

Sana is deploying the organization's websites in the local AWS availability zone as well as an availability zone across the country. This plan will provide enhanced uptime and scalability, but why did Sana choose an availability zone on the far side of the country? Because it is requrie by law Network traffic latency concerns Geographical dispersal Geographic tax reasons

A hot site

During a periodic review of security controls, Maria discovered that individuals who breach the network security perimeter would be able to then attack IoT systems that operate manufacturing. Manufacturing is a closed system and does not require internet connectivity. What type of solution is best suited for this? Air gap Faraday Cage Cold aisle screened subnet

Air gap

RAID 1

All data from one half of the drives are copied to the other half exactly. Mirrored

RAID 0

Data is spread to every drive in the array, which is like artifiically gluing two hard drives or more together

RAID 5

Data is striped across drives. Data is striped across drives, with one being used for parity for the data

Sam wants to implement a RAID array upon which data is striped across drives, with drives used for parity (checksum) of the data. Sam also wants to ensure that the system can handle more than one drive failing at a time. What RAID type should Sam use? RAID 1 RAID 5 RAID 6 RAID 10
