T/F When modifying the Schema, you should add administrators to the Schema Admins Group and then remove them after the task is completed.
Definition
True
Term
_______ is a command-line tool used for monitoring Active Directory. When run from a command prompt, this tool can perform connectivity and replication tests, report errors that occur, report DNS registration problems, analyze the permissions required for replication, and analyze the state of domain controllers within the forest
Definition
dcdiag
Term
What is the process of replicating DNS information from one DNS server to another?
Definition
zone transfer
Term
This resource record is responsible for identifying which server is the authoritative source of information for data within a domain.
Definition
SOA
Term
This resource record must be the first record in the zone database file.
Definition
SOA
Term
This resource record identifies the name of the server that is the authority for the particular zone or domain.
Definition
NS
Term
IF you wanted to create multiple records that point to the same ip address, which would you use?
Definition
CNAME (aka alias)
Term
T/F
MX records: The lower the preference number, the higher the priority.
Definition
True
Term
T/F
PTR records can be created automatically through the use of A records?
Definition
True
Term
AD clients rely on _____ records to tell them which server they need to authenticate to?
Definition
SRV
Term
T/F
A DNS query for david.hill.com can be resolved by a root name server.
Definition
False; a root name server only resolves the top level domain, the TLD DNS server only resolves the second level domain queries, the SLD server can resolve the Host record.
Term
______ queries are used between two or more DNS servers.
Definition
Iterative
Term
To conserve in internet bandwidth for your company, you can configure ____ ____, allowing DNS queries to be sent straight to a particular authoritative DNS server.
Definition
Conditional Forwarders
Term
How can configuring servers as forwarders help security in a Network that has 5 DNS servers, all of which are currently sending queries to the internet root name servers?
Definition
Use forwarders on 4 of the DNS servers to point to 1 server, leaving only one point of vulnerability
Term
A DNS server that hosts no domains and does not contain any zones is better known as a ____-____ server.
Definition
Caching-only
Term
When can you create a zone that contains multiple domains?
Definition
ONLY when those domains have a contiguous namespace like in a parent-child domain relationship. Not in a state where two children share the same parent because they are not connected directly (unless of course the children AND parent were in the same zone at once).
Term
T/F
You can create multiple zones on a single server and then delegate them out to other servers, leaving them responsible for hosting the zones.
Definition
True
Term
A Windows Server 2008 DNS server can contain up to how many zones?
2
32
64
Unlimited
Definition
Unlimited
Term
T/F
All zones share a database that contain resource records for the forest.
Definition
False; Each zone has its own database which contain records for the DOMAIN in said zone
Term
When creating a zone, if the "Store zone in Active Directory" box is not checked, the zone will be referred to as a ____ zone
Definition
Standard
Term
Administrators make changes to zone resource records in ______ zones.
Definition
Primary
Term
A _____ zone contains a master copy of the zones database
Definition
Primary
Term
T/F
When an Administrator wants to make a change to the zone database, they must do so from the Secondary Zone
Definition
False; a secondary zone is read-only
Term
To provide fault tolerance and to encourage NLB, you should always create at least ___ secondary zone(s) for every one primary zone
Definition
One
Term
T/F
Primary zones are usually stored on the same server as the secondary zone.
Definition
False; they are created and stored on separate servers.
(Or are they stored on separate appliction partitions. I say this bc of the multimaster traits of AD. It seems that being stored on a "server" is just not right since many servers partake in replication of AD data)
Term
(multiple answers)
What three resource records are found in a stub zone (A stub zone, remember, is a copy of a primary zone):
Definition
SOA
NS
Host records that identify authoritative servers for the zone.
Term
When are Zone transfers not necessary?
Definition
When the Zone is AD integrated because the zones are replicated (multimaster environment) between DC's along with other AD information.
Term
AXFR
Definition
Full zone transfer
Term
IXFR
Definition
Incremental Zone transfer
Term
T/F
It is not possible to create an AD integrated secondary zone, but you can configure an AD integrated primary zone to replicate to a standard secondary zone.
Definition
True
Term
Definition:
The application partition that is replicated to all domain controllers that are running the DNS server service in the domain.
Definition
Term:
DomainDNSZones
Term
Definition:
The application partition that consists of all domain controllers configured as DNS servers within the entire forest
Definition
Term:
ForestDNSZones
Term
Command line tool that allows you to create application partitions
Definition
ntdsutil
Term
What allows users to control access to files that they own (such as word docs and excel spreadsheets) and even who can print/forward emails?
Definition
AD Rights Management Services
(AD RMS)
Term
Fact:
In order to implement AD RMS on your network, you must have the following:
Server 2008 w/ RMS role running and IIS
A Database Server
A Client that is running RMS software

Term
What port is used by Active Directory to direct search requests to a global catalog server?
3629
3389
3268
3232
Definition
3268
When a user initiates a search for an object in Active Directory, the request is automatically sent to TCP port 3268, which is used by Active Directory to direct these requests to a global catalog server. One of the SRV records used by Active Directory refers to the global catalog, or _gc, service, which listens on port 3268 to respond to these requests.
