Answer 1

Cloud Infrastructure

Question 2

___________ are the primary storage unit for data.

Answer 2

Buckets

Question 3

What are the two main factors used in determining the appropriate disk type?

Answer 3

Speed and capacity

Question 4

__________ is measured in bytes,

Answer 4

Capacity

Question 5

___________ is typically measured in input/output operations per second (IOPS)

Answer 5

Speed

Question 6

___________ have been the storage standard for workstations and servers for decades, reliable, reasonably fast/priced

Answer 6

HDD, Spinning Disk

Question 7

_________ rely on flash memory to provide very fast access to data. Are the standard in end-user workstations and servers and are becoming more common in servers. more expensive but performance trade-off is worth it

Answer 7

Flash Memory, SSDs

Question 8

Answer 8

Hybrid disks

Question 9

An HDD use rapidly rotating disks called _________, coated with a magnetic material known as ________________

Answer 9

platters, ferrous oxide

Question 10

___________ is a high-performance storage device that contains no moving parts, ________ based flash memory

Answer 10

SSD, NAND

Question 11

_________ (Disk Striping) – Provides speed with no redundancy and requires a minimum of
_____ disks

Answer 11

RAID 0, 2

Question 12

___________ (Disk Mirroring) – Provides high degree of redundancy by writing across multiple
disks at once. Space is not efficiently used as data is written multiple times on multiple
disks. Requires a minimum of ____ disks.

Answer 12

RAID 1, 2

Question 13

____________ (Disk striping with parity) - provides a balance between performance, redundancy, and cost-effective capacity. Data is distributed across the stripes on the disks, as with RAID 0, but additional parity information is also written to the disks. This permits data to be recreated if one of the drives in the array fails. Requires a minimum of ______ disks

Answer 13

Raid5, 3

Question 14

___________(Disk striping with double parity) _ distributes data across a minimum of four disks the same way that RAID 0 and RAID 5 do, but also distributes parity information across two disks

Answer 14

RAID 6

Question 15

___________ - provides the same as RAID 0 but with mirroring. Rebuild times are fast, but the per-gigabyte storage costs are not as efficient as with RAID 5 or 6. Requires a minimum of _______ disks.

Answer 15

Raid 10, 4

Question 16

________ provides the striping associated with RAID 0 but includes disk striping with parity of RAID 5. Requires a _____ disk minimum but tolerates up too 2 disk failure

Answer 16

RAID 50, 6

Question 17

_____________ permits an organization to adjust where its data is being stored based on the performance, availability, cost, and recovery requirements of an application

Answer 17

Tiered storage

Question 18

Tiered storage, allows for movement of data from fast, expensive disks to slower less expensive disks using ____________________

Answer 18

Hierarchical storage management

Question 19

______ is organized into tiers based on the performance capabilities of each device

Answer 19

HSM

Question 20

Tier ___ data is mission critical, recently accessed or secure files and should be stored on expensive and highly available enterprise falsh drives such as RAID with parity. Tier ___ drives are ______ or pther high-speed disks

Answer 20

1, SSD

Question 21

Tier ___ is data the runs major business applications like email and resource planning software, is balanced between speed and cost

Answer 21

2

4, back-up tapes, HDDs

Question 24

____________ Is the foundation of a successful infrastructure

Answer 24

Storage

Question 25

___________ Is a storage system where servers directly connect to the storage devices without going through a network device

Answer 25

Direct Attached Storage

Question 26

____________ is a file-dedicated storage device that makes data continuously available for employees to collaborate over a network _____ devices are specialized servers that handle only data storage and file-sharing requests.

Answer 26

Network Attached Storage, NAS

Question 27

___________ is a dedicated, independent high-speed network that interconnects and delivers shared pools of storage devices to multiple servers

What are its three primary components?

Answer 27

Storage Area Network

• One or more servers that manage access to the data

-An isolated network between the servers and the storage infrastructure.

-The data storage infrastructure itself (HDDs, SSDs, etc)

Question 28

_____ allow organizations to connect disparate types of storage, such as tape and optical media.

Answer 28

SANS

Question 29

Data is divided into chunks called ________ and stored in sperate pieces. ____________ is not reliant on a server’s file system, and data chunks may be distributed across several storage devices

Answer 29

Blocks, Block Storage

Question 30

_____________ access is provided via shared file storage systems, such as Network File System and Common Internet file system. The __________ type is essentially a cloud-based NAS that shares folders to client computers whether they are on premises or in cloud infrastructure.

Answer 30

File Storage

Question 31

___________ also breaks the data into chunks, provides highly detailed metadata, is scalable, and cost efficient. ______does not write efficiently and is not suitable for content such as databases, it is best for data that is written once and read frequently
