the process that can be used by Windows Server 2003 DNS to clean up the DNS database when resource records are no longer required
What are the facts and requirements to raise the domain and forest functional levels?
one way operation (raised domain and forest functional levels can not be reversed without a complete reinstallation of the domain), each domain must be handled independently, the forest functional level cannot be raised until all domains in a forest have been raised to at least Windows 2000 native, logged on as a member of the domain admins group to raise the domain functionality, logged on as a member of the enterprise admins group to raise the forest functionality
What is a short cut and what are realm trusts?
trust established to shorten the number of hops required to gain access to a domain; trust established with a non-windows platform that uses kerberos as the authentication method
What are the characteristics of a site?
logical structure that can been seen in ADUC, physical network structure affects the efficiency of active directory replication
What is the default location for computers in sites and services?
Default-First-Site-Name
What is the update sequence number and what is a time stamp?
assigned by domain controllers when an object or attribute has changed; placed on each change that occurs
What is the rule of 3?
No single domain controller should be more than 3 network hops away from an originating domain controller
How often does the KCC run?
Knowledge Consistency Checker; every 15 minutes
What are cost, schedule, and frequency for site sinks and what are their default levels and ranges?
The three attributes of site link objects; Cost (allows admin to define the path that replication will take), Schedule (determines when the link can be used to replicate information), Frequency (provides the how often information regarding the replication schedule); Default: 180 minutes but can be as little as 15; 10,080 minutes is a week
What is the difference between intersite and intrasite replication?
Intra: designed to control replication traffic over slow WAN links
Inter: site links, connection between two sites that are logical and transitive
What are the functions of the global catalog?
Central Repository for forest wide data; facilitate searches in the forest, resolve UPNs, provide universal group membership information
What is Universal Group caching and how often is it refreshed?
non global catalog domain controllers can process logons without contacting a global catalog server; every 8 hours
What are the 5 FSMO roles?
Domain Naming Master (create and delete domains in the forest), Relative Identifier (RID) Master (responsible for generating a pool of identifiers that are used when new accounts, groups, and computers are created), Infrastructure Master (replicating changes to an objects SID or distinguished name (DN)), Primary Domain Controller (PDC) emulator (provides backward compatibility for computers that are considered to be downlevel clients), Schema Master (making master changes to the active directory schema)
When can we convert groups?
Any time as long as the domain functional level is set to Windows 2000 native or higher
When do we have Universal Groups?
When consolidating groups and accounts that either span multiple domains or span the entire forest
What is CSVDE and LDIFDE used for?
Comma-Seperated Value Directory Exchange (import or export active directory information from a comma-separated value, can not modify or delete existing objects); LDAP Date Interchange Format Directory Exchange (same as CSVDE but can make modifications to the schema if necessary)
What does Microsoft say is a strong password?
one that follows guidelines that make it difficult for a potential hacker to crack; combination of minimum length, history, character types, and age (6-8 characters, upper and lowercase letters, numbers,and symbols, at least one of every character type, different that previous passwords
What do we have to do in order to use a smart card?
implement a PKI (public key infrastructure)
What does "Run as..." do and what service is required to use it?
allows you to maintain your primary logon as a standard user and creates a secondary session for access to an administrative tool; secondary logon service to be running
What does an OU look like and how do you hide it?
Flat or Pyramid; modify the ACL
What is the move option?
safe method of moving objects from one OU to another in ADUC
What are GPC and GPT?
Group Policy Container (active directory object that stores the properties of the GPO); Group Policy Template (located int he Policies subfolder of the Sysvol volume, stores policy settings such as security settings and script files
What are 2 default group policies?
Default Domain Policy (linked to the domain and its settings affect all users and computer in the domain); Default Domain Controllers Policy (linked to the Domain Controllers OU and it affects all domain controllers within this object)
What are the 3 states setting can be in?
Software Settings, Windows Settings, Administrative Templates
How are group policies processed and what are exceptions?
Local Policies, Site Policies, Domain Policies, OU Policies; No Override (force the settings to flow down through the active directory without being blocked my child domains), Block Policy Inheritance (set on a site, domain, or OU to block all policies from parent containers flowing to this container), Loopback (setting that provides an alternative method of obtaining the ordered list of GPOs to be processed for the user)

at least one domain controller running Windows Server 2003 must be present, only evaluated on XP Professional or Server 2003, must have an outcome of true in order for GPO to be applied, only one WMI filter per GPO, can be linked to multiple GPOs once created
