Question 1

What is a basic disk?

Answer 1

One that uses the MBR or GPT scheme

Question 2

Explain the layout of a MBR?

Answer 2

The first sector contains the MBR
MBR holds partition tables
Max 4 partitions
Max 2.2 TB

Question 3

What is an extendable partition

Answer 3

Non-bootable, but can hold logical partitions. These do not receive a drive letter

Question 4

What is a Logical Partition

Answer 4

Logical partitions are found inside a extended partition and will receive a drive letter

Question 5

What is a dynamic disk

Answer 5

Instead of partitions they hold volumes. Volumes can span many disks, and have many features such as RAID

Question 6

What is GPtT

Answer 6

GUID (Global Unique Identifier) Parition Table
Has a max of 128 partitions, but no limit on the size of the partitions
A header is placed at the front and back as a backup and is broken up into sectors called LBA

Question 7

What is the purpose of a Swap partition

Answer 7

Used in a similar fashion to RAM. This is used in Linux/unix systems. Windows uses it’s own page file system.

Question 8

Outline the FAT(16) file system

Answer 8

Name: File Allocation Table

• Each sector stores 512 bytes organized like a spreadsheet with one column holding a hexadecimal number, and the right column showing the status
• Bad sector = FFF7
• Max size of 32 MB
• Max size of 2 GB with CLUSTERING

Question 9

How does the FAT system work

Answer 9

• Windows looks for 0000 (good)
• FFFF marks the end of file
• The folder name and cluster number is added to the folder list.

Question 10

What is clustering

Answer 10

In a FAT system the sectors are grouped together

Question 11

Outline FAT32 System

Answer 11

Clusters = 4 KB
32 bits long
Max 2 TB parition
Max file size = 4 GB
Good for flash drives

Question 12

Outline the NTFS file system

Answer 12

New technology file system
Uses a master file table in the middle of the drive to avoid corruption.
Security feature: can control access to files
Other Features: compression and encryption
Max partition size = 16 TB (Dynamic disk) or 2 TB (basic)

Question 13

Outline exFAT/FAT64

Answer 13

File support up to 16 TB
Max file size: 16 EB 
Max patition size 64 zettabytes (theoretical)
Recomended partition: 512 GB
Use on flash drives
Doesn't have features NTFS does.

Question 14

Outline ext4 file system

Answer 14

Fourth extended file system
Used in linux
Volumes max of 1 exabyte
Files max = 16 TB
Backwards compatible, can also read/write to NTFS

Question 15

What is a good standard to follow for using FAT or FAT32

Answer 15

If a disk is less than 4 GB use either of those

Question 16

What could be the problem if a dynamic disk is not showing

Answer 16

Coule be recognized as a foregin drive which windows can import

Question 17

What are storage spaces

Answer 17

Functions Similar to RAID by grouping physical drives together

Question 18

Explain Simple Space (storage spaces)

Answer 18

Forms one single virtual drive without any resiliency

Question 19

Explain Mirrored spaces (storage spaces)

Answer 19

Keeps mroe than one copy of data on the drive.

• 2 way mirror requires 2 drives minimum
• 3 way miror requires 5 drives minimum

Question 20

Explain parity spaces (storage spaces)

Answer 20

For every 10 GB of data stored there needs to be 15 GB installed as it requires large overhead

Question 21

What is the purpose of thin provisioning

Answer 21

Allows you to tell the system there is more space than actually present and will alert you when you need a new physical drive.

Question 22

What maintenance is required on drives?

Answer 22

Error checking will sometimes fix bad or missing filenames, and match up parent and child folders that were lost

Question 23

What areas need to be cleaned up regularly

Answer 23

Recycle bin
Temporary internet files
Downloaded Program files
Temporary Files
