CNIT 242 EXAM 2 QUESTIONS AND ANSWERS
What is a Full Backup> - Answer -disregards archive bit setting
time consuming
takes up a lot of media
backs up everything
two types of selective backups? - Answer -Differential and Incremental
What is a differential Backup? - Answer -Backs up files that have been changed since
last FULL backup.
easier to restore than incremnetal
What is incremnetal backup/ - Answer -Backs up files that have been changed since
the last backup of any kind.
least media
hardest to restore
Most commonly used media - Answer -magnetic tape
magnetic tape/ - Answer -sequential not random access
inexpensive
have to clean the heads
Optical Storage/ - Answer -faster than magnetic tape
more often used for archival purposes instead of backups.
Are sites connected to eachother via a slower or ffaster WAN network? - Answer -
Slower
An Active directory cannot span multiple sites. T or F - Answer -False
Can a single IP subnet span multiple Sites? - Answer -NO
A single site may contain multiple AD domains. T or F - Answer -True
What is FSMO? - Answer -Flexible Single Master Operator
Shema Master - Answer -Forest Wide -
The DC that is allowed to make changes to the schema
Domain Naming Master - Answer -Forest Wide - The DC responsible for forest wide
namespace
, PDC Emulator - Answer -Domain Wide - Used for backward compatibility with windows
NT DCs
Relative ID master - Answer -Domain wide - Responsible for making sure that SIDs are
unique within the domain.
Infrastructure Master - Answer -domain wide - Responsible for updating other domains
with changes that occur locally
Should you assign the infrastructure Master to the same DC as the global catalog/ -
Answer -NO
In single domain forests... - Answer -All FSMO roles can exist on the first DC in the
forest
When are FSMO roles moved? - Answer -Performance, fault tolerance, or upgrades
server downtime
Seizures happen when the source server is unavailable. Once a role is seized should
the original server come back on line? - Answer -NEVER
Command line tool for seizing? - Answer -ntdsutil.exe
What technologies do SSDs use? - Answer -- RAM
- NAND based
NAND based ssd? - Answer -retain memory without power
slower then RAM based
RAM based SSD? - Answer -Faster Access
require constant power
SSD advantages? - Answer -Fast seek times
no moving parts
silent
SSD disadvantages? - Answer -expensive
wear leveling
limited cpacities
power requirements
little improvement to sustained read/wrote performance
iSCSI initiator - Answer -Device that originates a session to a storage device
Typically a computing host
iSCSI Target - Answer -The storage device to which an initiator connects
