Chapter 1: Introduction to Virtualization and Microsoft
Solutions
Articulate the key value propositions of virtualization. Virtualization solves
the numerous pain points and limitations of physical server deployments today.
Primary benefits of virtualization include consolidation of resources, which increases
resource utilization and provides OS abstraction from hardware, allowing OS mobility;
financial savings through less server hardware, less datacenter space, and simpler
licensing; faster provisioning of environments; and additional backup and recovery
options.
Master It How does virtualization help in service isolation in branch office
situations?
Solution Virtualization enables the various roles required (such as domain
controllers and file services) to run on different operating system instances,
ensuring isolation without requiring large amounts of hardware.Understand the differences in functionality between the different versions
of Hyper-V. Windows Server 2008 introduced the foundational Hyper-V capabilities,
and the major new features in 2008 R2 were Live Migration and Cluster Shared
Volumes (CSV). Windows 2008 R2 SP1 introduced Dynamic Memory and RemoteFX.
Windows Server 2012 introduced new levels of scalability and mobility with features
such as Shared Nothing Live Migration, Storage Live Migration, and Hyper-V Replica
in addition to new networking and storage capabilities. Windows 2012 R2 Hyper-V
enhances many of the 2012 features with generation 2 virtual machines, Live
Migration compression and SMB support, new Hyper-V Replica replication
granularity, and Hyper-V Replica Extended replication. Windows Server 2016 builds
on this with shielded VMs providing new levels of security for virtual environments,
containers for new ways to deploy and manage applications, SDNv2, and other
features and management enhancements.
Master It What is the largest virtual machine that can be created on Windows
Server 2012 Hyper-V, and does this change for Windows Server 2016 Hyper-V?
Solution The largest virtual machine possible in Windows Server 2012 R2 is 64
vCPUs with 1TB of memory. This changes in Windows Server 2016 to 240 vCPUs
and 12TB of memory.
Master It What features were enabled for Linux virtual machines in Windows
Server 2016 Hyper-V?
Solution A key feature enabled for Linux in Windows Server 2016 Hyper-V is
Secure Boot. Additionally, many other features new to Windows Server 2016 work
with Linux, such as hot-add of memory.
