CNIT 242 EXAM 2 QUESTIONS & ANSWERS
Benefits of a snapshot - Answer -Can go back to a snapshotted state of an operating
system
Benefits of ESXi - Answer -- free download and provides most functionality
-special VM for console functionality
installable can run from USB or network boot
-long term direction
Benefits of VMware - Answer --owns the enterprise virtualization market
-mature, 10+ years old technology
what is vClient - Answer -Used to access ESXi severs to manage VMs
What is vCenter - Answer -management of machines and servers
What is vSphere - Answer -vSphere is a suite of software/services including vCenter,
and vMotion
what is vMotion - Answer -the ability to move running VMs between servers
Bare metal virtualization - Answer --Virtualization layer is installed directly on the
hardware
-No Separate OS is necessary
-More efficient than hosted architectures
Host based virtualization - Answer --the virtualization layer is installed on top of existing
OS as an application
-Other programs can run a long side of the virtualization software
-Typically allows the best support for host hardware
Raid 0 - Answer --Data is distributed across multiple disks
-Increased performance
-No redundancy - if one disk fails, al data is lost
Raid 1 - Answer --Data is duplicated across multiple disks
-No increased performance
-Fault tolerant - if a drive fails, this copy can be used
Raid 5 - Answer --Data is striped across multiple disks
-Parity data is kept for each set of stripes
-Increased performance
-Provides some redundancy
, Raid 10 - Answer --Stripes data across multiple disks, which are then mirrored
-Increased performance
-Fault tolerant
What are the FSMO roles - Answer -Schema master, Domain Naming Master, PDC
Emulator, RID Master, Infrastructure Master
What is the schema master - Answer --Scope: Forest-wide
-The DC that is allowed to make changes to the schema (definitions of things in the
database) - only one in the entire forest
what is the Domain naming master - Answer --Scope: Forest-wide
The DC responsible for the forest-wide namespace - MUST be on a DC that is also a
Global Catalog Server
What is the PDC emulator - Answer --Scope: Domain-wide
-Used for backward compatibility with Windows NT DCs & for propagating password
changes quickly across all DC's in the domain (not hours - but seconds) -Should not be
same machine as Global Catalog, ideally
What is the RID master - Answer --Scope: Domain-wide
-Responsible for making sure that SIDs are unique within the domain - SID is long
security ID.
-All SIDs in a domain are the same up to the last 32 bits, called the RID.
-Makes sure those 32 bits remain unique for each object in domain
what is the Infrastructure master - Answer --Scope: Domain-wide
-Maintains references to objects located in another domain(phantoms)
When would you move roles - Answer --Performance, fault tolerance, or upgrades
-Server downtime or maintenance
-Server decommissioning
When do you transfer roles - Answer --Transfers are preferred and used when both
source & destination servers are available
When do you seize roles - Answer --Seizures happen when the source server is
unavailable
-if a role is seized, the original should never be brought back online
