F04 Physical Structure Flashcards
1
Q
Define Domain Controller
A
- A server in an AD Forest that is running Window Server 2003 or better network operating system and actively providing directory services is known as a domain controller.
- A DC has a complete copy of every object in the domain.
2
Q
Flexible Single Operations Master
A
- FSMO
- Each domain controller can have multiple roles.
3
Q
Schema Master
A
- First DC in the forest
- Controls the master list of objects and attributes in the AD Structure.
- AD Schema cannot be modified unless SM is available.
- Forest level role
4
Q
Domain Naming Master
A
- Forest level role
- The DNM records the additions and deletions of domains in the forest.
- Domain cannot be added/deleted if DNM is not available.
5
Q
RID Master
A
- Objects have unique Security Identifier (SID)
- 1st Part: domain specific 2nd Part: uniquetoobject
- RID master creates SID blocks and assigned them to Dc.
- DC uses block of RID to complete SID object.
- If RID master is not available then object cannot be added to domain if all RID are used.
- Domain Level Role
6
Q
Primary Domain Controller (PDC) Emulator (1st function)
A
- Process password changes IOT ensure all DC know of PW changes.
- All PW changes get recorded on PDC first.
- this ensure users can lon on to domain if replication has not occured between DC.
- If different DC have different user password then PDC emulator resolves this issues.
7
Q
Primary Domain Controller (PDC) Emulator (2nd function)
A
-Manage group policy updates within a domain.
8
Q
Primary Domain Controller (PDC) Emulator (3rd function)
A
- Provides a master time source for the domain.
- PDC in the forest root domain is the time master for the entire forest.
- Important because because AD relies on time stamps to manage objects.
9
Q
Infrastructure Master
A
- The IM master is the master catalog of all objects in the domain.
- All changes are reported first to the IM and then replicated out to the other DC.
- Domain level role.
- Without IM object cannot be added to the domain.
10
Q
3 DC partition
A
- Schema Partition
- Configuration Partition
- Domain Partition
11
Q
DC Schema Partition
A
-Has a copy of the schema of the forest
12
Q
DC Configuration Partition
A
- Defines the physical sturucture of AD.
- The Servers and the roels that they play
13
Q
DC Domain Partition
A
-Domain partition is where they keep a copy of all of the objects in the domain.
14
Q
IP Bridgehead
A
- IP bridgehead control replication into and out of the site.
- DC replicate freel within a site.
- All changes are sent to the IPB and then sent over the WAN.
15
Q
Replication connections
A
- Replication connections across the WAN are configured between sites and contain costs and interval.
- Cost is the available bandwidth and delay.
- Replication interval is set by adminitrator.
