Name the 4 versions of Windows Server 2012 R2

Back 12

Datacenter : full windows server functionality with unlimited virtual instances

Standard : full windows server functionality with 2 virtual instances.

Essentials : for upto 25 users and 50 devices. Has a simpler interface and preconfigured connectivity to cloud based services but no virtualization rights

Foundation : upto 15 users . A general purpose server with basic functionality but no virtualization rights.

Front 13

LBFO

Back 13

Load Balancing and Failover , also known as NIC teaming to group multiple network adapters on a system .A maximum of 32 network adapters can be setup in a NIC team . It is a very common practice when setting up virtualization and is one way that you can have load balancing with Hyper-V .

It allows a virtual machine to use virtual network adapters in Hyper -V

Front 14

PXE network devices

Back 14

Preboot Execution Environment. These are network interface cards that can talk to a network without the need for an operating system . These have a set of preboot commands within the boot firmware. Most of the machines for which you are using WDS do not have an operating system on the computer. For the same reason , you must set up DHCP to accept PXE machines.

Front 15

Name 2 types of Partition styles which are used to initialize disks.

Back 15

Master Boot Record( MBR) and GUID partition table (GPT)

Front 16

MBR

Back 16

MBR has a partition table that indicates where the partitions are located on the disk drive and with this partition style , only volumes upto 2 TB are supported.

An MBR drive can have upto 4 primary partitions or can have 3 primary partitions and one extended partition that can be divided into unlimited logical drives.

Front 17

GPT

Back 17

Can support volumes upto 18 EB (18,874,368 million terabytes ) and 128 partitions

Front 18

What is the difference between basic disk and dynamic disk ?

Back 18

Basic disks are divided into partitions and can be used with previous versions of windows. Dynamic disks are divided into volumes and can be used with Windows 2000 server and newer releases.

When a disk is initialized , it is automatically created as a basic disk , but when a new fault-tolerant (RAID) volume set is created, the disks in the set are converted to dynamic disks. Fault tolerance features and the ability to modify disks without having to reboot the server are what distinguish dynamic disks from basic disks.

A basic disk can simply be converted to a dynamic disk without loss of data. When a basic disk is converted , the partitions are automatically changed to the appropriate volumes. However , converting a dynamic disk back to a basic disk is not as simple. All the data in the dynamic disk must be backed up or moved . Then, all the volumes on the dynamic disk have to be deleted . The dynamic disk can then be converted to a basic disk. Partitions and logical drives can be created, and the data can be restored.

Front 19

How a volume set is created ?

Back 19

A volume set is created from volumes that span multiple drives by using the free space from those drives to construct what will appear to be a single drive.

Front 20

What is the difference between simple volume and spanned volume ?

Back 20

Simple volume uses only one disk or a portion of disk whereas spanned volume is a simple volume that spans multiple disks , with a maximum of 32.

Front 21

What is the difference between simple volume and spanned volume ?

Back 21

Simple volume uses only one disk or a portion of disk whereas spanned volume is a simple volume that spans multiple disks , with a maximum of 32.

Front 22

Striped volume

Back 22

Stores data in stripes across two or more disks. A striped volume gives you fast access to data but is not tolerant nor can it be extended or mirrored. If one disk in the striped set fails , the entire volume fails .

Front 23

What is the difference between simple volume and spanned volume ?

Back 23

Simple volume uses only one disk or a portion of disk whereas spanned volume is a simple volume that spans multiple disks , with a maximum of 32.

Front 24

Striped volume

Back 24

Stores data in stripes across two or more disks. A striped volume gives you fast access to data but is not tolerant nor can it be extended or mirrored. If one disk in the striped set fails , the entire volume fails .

Front 25

Mirrored volume

Back 25

Duplicates data across 2 disks. This type of volume is fault tolerant.

Front 26

RAID 5

Back 26

It stores data in stripes across three or more disks. This type of volume is fault- tolerant because if a drive fails , the data can be re-created from the parity off of the remaining disk drives . Operating system files and boot files cannot reside on the RAID-5 disks.

Front 27

Storage spaces

Back 27

Windows server 2012 R2 allows an administrator to virtualize storage by grouping disks into storage pools which can then be turned into virtual disks called storage spaces . Storage spaces allows an administrator to take free space from storage pools and create virtual disks which themselves are called storage spaces .

Front 28

Name three types of storage space resiliency

Back 28

Mirror , parity and simple(no resiliency )

Front 29

Raid 0

Back 29

Disk striping

Front 30

Raid 0

Back 30

Disk striping

Front 31

Raid 1

Back 31

Disk Mirroring

Front 32

MPIO

Back 32

Multipath I/O , allows redundant physical paths connected to a storage device . It also load balances the data traffic across both paths to the storage device , virtually eliminating bandwidth bottlenecks to the computer.

Front 33

Microsoft DSM

Back 33

Microsoft Device Specific Module, is a driver that communicates with the storage devices to provide MPIO and also provides the chosen load-balancing policies.

Front 34

Failover

Back 34

No load balancing

Front 35

Failback

Back 35

has a secondary backup path

Front 36

Dynamic Least Queue Depth

Back 36

I/O will route to the path with the least number of outstanding requests

Front 37

Weighted path

Back 37

Paths are assigned a numbered weight. I/O requests will use the path with the least weight - the higher the number, the lower the priority.

Front 38

iSCSI

Back 38

Internet Small Computer System Interface, an interconnect protocol used to establish and manage a connection between a computer(initiator) and a storage device(target) . Each initiator is identified by its iSCSI Qualified Name (iqn) and is used to establish its connection to an iSCSI target. It was developed to allow block-level access to a storage device over a network

Front 39

Which port does iSCSI use to establish the connection between initiator and target ?

Back 39

TCP port 3260

Front 40

NAS

Back 40

Network Attached Storage , connects through the use of Common Internet FIle System (CIFS) or Network File System (NFS)

Front 41

Name 2 applications that requires block-level access (direct access) to storage

Back 41

Microsoft Exchange and Microsoft SQL

Front 42

What advantage does iSCSI has over Fibre Channel ?

Back 42

it can provide security for the storage devices. iSCSI use CHAP or MS - CHAP for authentication and Internet protocol security (IPsec) for encryption

Front 43

Do we need any additional software to install iSCSI in windows Server 2012 R2 ?

Back 43

No its plug and play as Microsoft iSCSI initiator is built into the operating system.

Front 44

iSNS

Back 44

Internet Storage Name Service , allows for central registration of an iSCSI environment because it automatically discovers available targets on the network. The Microsoft iSCSI initiator includes an iSNS client that is used to register with the iSNS

The iSNS feature maintains a database of clients that it has registered either through DHCP discovery or through manual registration.
