Dynamic Disks
Single partition that occupies the entire disk. You can create an unlimited number of volumes out of the space in that partition. Supports several different types of volumes.
What are a couple of valid reasons as to why administrators might want to install their Windows Server 2012 R2 servers by using the Server Core option?
-A server core installation can be converted to the full GUI without re-installing the operating system. -The new Server manager in Windows Server 2012 R2 makes it much easier to administer servers remotely.
Minimal Server interface
-Server manager -MMC -Device Manger -Powershell in order to configure, remove “Server Graphical Shell” in roles and features.
Roles available in Server core installation
ADCS ADDS ADLDS ADRMS DHCP DNS File an Storage Hyper-V Print and Document Services Remote access Web Server (IIS) WSUS
Which of the following command-line tools are used to join a computer to a domain?
netdom.exe
What powershell command is used to completely remove the GUI installation files from the system?
Uninstall-WindowsFeature Server-Gui-Mgmt-Infra,Server-Gui-Shell -Remove
Storage pool
Find the storage pool wizard. Disks that are eligible don’t have partitions or volumes. Vice Versa for in-eligble disks.
Mount in the following Empty NTFS Folder
Type path to an existing NTFS folder or browse. The entire contents of the new drive will appear in the foler you specify.
What volume types supported by Windows Server 2012 R2 provide fault tolerance?
-A mirrored volume writes duplicate copies of all data to two disks, thereby providing fault tolerance. -A RAID-5 volume writes data and parity information on multiple disks, thereby providing fault tolerance.
Spanned Volume
Consists of space from 2 to 32 physical disks all of which must be dynamic disks.
Migrating Roles
Preferred method for an upgrade. -Between versions (i.e. 2003 to 2012) -Between platforms (32 bit to 64 bit) -Between editions (Essentials to Standard) -Between physical and virtual instances -Between Installation options (Server Core to Server with a GUI)
Roles not available in Server core installation
ADFS Application server (deprecated) Fax server Network Policy and access services Remote desktop Gateway Remote desktop session host Remote desktop web access Volume activation services Windows deployment services.
Simple Volume
Consists of space from a single disk. You can extend it to multiple disks to create spanned or striped Volumes as long as it’s not the boot volume. Can extend to any adjacent unallocated space on same disk, or with limitations shrink the volume by deallocating any unused space in the volume.
Downside to NIC Teaming
Large TCP sequences on the network such as Hyper V live migration will avoid using multiple adapters to minimize lost and out of order TCP segments. There will not be any performance increase. Dynamic mode, however, splits these large TCP sequences into smaller units and distributes them among the NICs. This is default load-balancing mode in 2012 r2.
Installation Requirements
-1.4-GHz 64-bit processor -512 MB RAM -32 GB available disk space -Super VGA (1024 x 768) or higher resolution. -Keyboard and mouse. -Internet access.
Do not assing A drive letter or drive path
Create partition but not ready for use. It’s left unmounted and inaccessible. When you want to mount it, just assign a drive letter.

Uninstall-WindowsFeature Server-Gui-MGMT-Infra, Server-Gui-Shell -Restart
NIC Teaming: Switch Dependent Mode
All network adapters are connected to the same switch, providing a single interface with their combined bandwidth. Static teaming: generic mode that balances the traffic between adapters in the team or use Link Aggregation protocol (IEEE 802.3ax)
What is not true about the server manager?
What’s not true is that Server manager can deploy roles to multiple servers at the same time.

Thin
Allocates space from the storage pool to the disk as needed up to the maximum specified size.
WinSxS
Used for features on demand. Serves as an installation medium for features possibly needed down the road. You can activate features from the files copied from setup from this folder.
Perform A quick Format
Formats disk without checking for errors. Faster, but not recommended. When you check for errors, the system looks for and marks bad sectors on the disk so that your clients will not use those portions of the disk.
Windows Server Migration Tools
Standard feature located within Roles and features. Must be installed on source and destination servers.
Server core
Perform postinstallation tasks from the command line.
Delegate Administration
Assign the appropriate permissions for your environment for certain people to manage certain things.
Allocation unit size
Specify file system cluster size. Signifies the basic unit of bytes in which the system allocated disk space. i.e. if client uses consistently small files, you might set the allocation unit size to a smaller cluster size.
VHD
Original and more compatible format, which supports files of up to 2,040GB.
What operations can you not perform on a service by using Server manager?
-Disable a service. -Configure a service to start when the computer starts.

Which features must be removed from a full GUI installation of Windows Server 2012 R2 in order to convert it to a Server Core Installation?
-Graphical management tools and infrastructure -Server graphical shell.
RAID-5 Volume
Consists of space on three or more physical disks, all of which must be dynamic. Allows for 1 physical disk failure. Write performance suffers due to parity calculations.
Mirrored Volume
Consists of identical amount of space on two physical disks, both of which must by dynamic disks.
Install Roles via exported config file (Powershell)

Nic Teaming: Switch Independent Mode
All network adapters are connected to different switches, providing alternative routes through the network. Active/Active: config leaves all net adapters functional, increasing throughput. Active/Standby: Config one adapter is left offline to function as a failover.
Parity (Storage Pool)
Requires the pool to contain atleast three physical disks and provides fault tolerance by striping parity information along with data.
What terms is the name of the directory where Windows stores all the operating system modules it might need to install at a later time?
WinSxS
GPT
Existed since late ’90s, but no x86 version of Windows prior to 2008 and Vista. Not eligible to be boot disk. Only option that server manager supports. 128 volumes can be created.
What features must be added to a windows server 2012 r2 core installation to convert it to the minimal server interface?
Graphical management tools and infrastructure.
Fixed
Allocates the maximum specified amount of space to the disk immediately on creating it.
VHDX
New version of the format that supports files of up to 64TB but can be read only by computers running Windows Server 2012 and Windows Server 2012 R2
Max Hardware Configuration
-640 processors -4 TB of RAM -64 failover cluster nodes
What best describes the requirements for extending a volume on a dynamic disk?
-When extending a simple volume, you can use only the available space on the same disk. If you extend the volume to another disk, it is no longer simple. -You can extend a simple volume across additional disks if it is not a system volume or a boot volume.
Storage Solution Factors
-Amount of storage the server needs. -Number of users who access the server at the same time. -Sensitivity to the data being stored. -Importance of data organization.
A JBOD drive array is alternative to which of the following storage technologies?
A JBOD array is an alternative to a RAID array that treats each disk as an independent volume.
Minimal Server Interface (Items omitted)
Omitted elements to enhance performance: -IE -Desktop -File Explorer -Windows 8 desktop apps -Programs and features -Network and sharing center -Devices and Printers Center -Display -Firewall -Windows Update -Fonts -Storage spaces
What is true about striped volumes?
-Striping provides improved performance because each disk drive in the array has time to seek the location of its next stripe while the other drives are writing. -If a single physical disk in the striped volume fails, all the data in the entire volume is lost.
Windows Server 2012 R2 Foundation
Scaled down. Designed for small businesses that require basic server features such as: file & print services, and application support. Comes pre-installed with server hardware. No virtualization rights. Limited to 15 users. 1 POSE instance.

Storage pool creation (powershell)
New-StoragePool -FriendlyName -StorageSubSytemFriendlyName -PhysicalDisks
MBR
Been around before Windows and still a common partition style for x86 and x64-based computers. 4 volumes can be created.
On a new server running Windows Server 2012 R2, Morris created a storage pool that consists of two physical drives holding 1 TB each. Then he created three simple virtual disks out of the space in the storage pool. Using the disk Management snap-in, Morris then created a RAID-5 volume out of the three virtual disks. 1.) In What way is Morris’s storage plan ineffectual at providing fault tolerance? 2.)Why will adding a third disk to the storage pool fail to improve the fault tolerance of the storage plan? 3.) How can Morris modify the storage plan to make it fault tolerant?
1.) Morris created a Raid 5 out of virtual disks created out of a storage pool that has only two physical disks. Raid 5 can only provide FT by storing data on 3 disks. 2.)Adding a 3rd disk doesn’t guarantee FT because there is no assurance that each of the three virtual disks exists on a separate individual disk. 3.)To make the plan fault-Tolerant, Morris should delete the three simple virtual disks and create on new virtual disk by using either the mirror or parity layout option.
Storage Spaces
concatenates storage space from individual physical disks and allocates that space to create virtual disks of any size supported by the hardware. Similar to SAN, but uses direct attached disks or simple external JBOD arrays. .
Which NIC teaming modes provides fault tolerance and bandwidth aggregation?
Switch independent mode. It provides separate paths to separate switches.
Obtain the correct designations for storage subsystem and physical disks
-Get-StorageSubSystem -Get-PhysicalDisk
Storage pool
Used by storage spaces. Spans multiple drives invisibly providing accumulated storage resource that administrators can expand or reduce as needed by adding disks to or removing them from the pool.
Mirror (Storage Pool)
Requires the pool to contain at least 2 physical disks and provides fault tolerance by storing identical copies to every file. Two physical disks provide protection against a single disk failure. Five physical disks provide protection against 2 disk failures.
Windows Server 2012 R2 Standard
Includes the full set of 2012 R2 features and differs from Datacenter edition only in the number of Virtual machine instances permitted by the license. 1 POSE instance 2 VOSE instances
NTFS
Preferred file system for a server. Improved support for larger hard drives than FAT, and better security in the forma of encryption and permissions that restrict access by unauthorized users.
Prepping for an Upgrade
-Check hardware compatibility -Check disk space : Sufficient disk space needed on partition where the old OS is installed. -Confirm software is signed: kernel-mode software such as device drivers must be signed or it will not load. The upgrade will abort or you will receive errors. (You can disable the driver signature by pressing F8 on boot)
FAT
Lacks security that NTFS provides. Any user who gains access can ready any file without restriction. Disk limitations. FAT32 can’t handle a partition greater than 32GB or a file greater than 4GB. FAT no hard disk greater than 4 GB or file greater than 2 GB.
Windows Server 2012 R2 Essentials
Nearly all features included in Standard and Datacenter; however, does not include Server Core, Hyper-v, and ADFS. Limited to one physical or virtual server instance and max 25 users. 1 (POSE or VOSE)
Shared Folder Strategy
-What folders will you share -What names you will assign to the shares. -What permissions you will grant users to the shares -What offline Files settings you will use for shares.
what needs to be enabled for file shares to be accessible over the network?
Network discovery
Server Message Blocks (SMB)
SMB is the standard file sharing protocol used by all versions of Windows.
Network File System (NFS)
NFS is the standard file sharing protocol used by most UNIX and Linux distributions.
