In windows DNS server,

Primary Zone: In this, the file is saved as normal text file with filename (.dns).
Secondary Zone: It maintains a read-only copy of zone database on another DNS server.  Also, it acts as a back-up server to the primary server by providing fault tolerance and load balancing
Stub Zone: It consists of a copy of name server and SOA records which is used for reducing the DNS search orders.

To do that, you have to go to,

gponameà  User Configuration à Windows Settings à Remote Installation Services à Choice Options

6)      What does it mean by “tattooing” the Registry ?

“ Tattooing” the registry means user can modify and view user preference that are not stored in the maintained portions of the Registry.  Even if the group policy is changed or removed, the user preference will still persist in the registry.

The caching only DNS server provides information related to queries based on the data it contains in its DNS cache.

11)   Explain what is the way to configure the DHCP server such that it allocates the same IP address to certain devices each time the address is removed?

To configure the DHCP server, you can create a reservation for the device.  To create a reservation, you must know the MAC hardware address of the device.  To determine the MAC address for a network device you can use the ipconfig or nbs tat command line utilities.

13)   Explain what is SYSVOL folder?


It is a set of files and folders that is stored on the local hard disk of each domain controller in a domain and are replicated by the FRS ( File Replication Service).  These files contain group or user policy information.

14)   Explain what is the difference between a thread and a computer process?

Computer Process: In computing, a process is an instance of a computer program that is executed sequentially by a computer system which can run several computer programs concurrently.

Thread: A thread is a several executable program that work together as a single process.  For instance, one thread might send an error message to the user; another might handle error signals while the third thread might be executing the original action.

On separate drives it allows you to combine one or more volumes so that they are accessed by a single drive letter

17)   Explain what is the purpose of deploying local DNS servers?

A local DNS server provides the local mapping of fully qualified domain names to IP addresses.  To resolve remote requests related to the domains names on your network, local DNS servers can provide record information to remote DNS servers.

AD database is saved in %systemroot%/ntds.  Files that controls the AD structure are

ntds.dit
edb.log
res1.log
res2.log
edn.chk
21)   Explain what is the major difference between NTFS ( New Technology File System) or FAT (File Allocation Table) on a local server?

For local users FAT (File Allocation Table) and FAT32 provides security, while NTFS ( New Technology File System) provides security for domain users as well as local users.  NTFS provides file level security which is not possible through FAT32.

Configuration Partition– it is a partition that stores all the data of Active Directory. The data comprises site-link, Site, subnet etc. This partition copies all domain controllers that are available in the Forest.

Application Partition– it stores the information of applications in Active Directory. For examples DomainDNSZones and ForestDNSZones.

Schema Partition–It stores all the information of the objects and their qualities; it copies to other domain controllers in the Forest

Domain Partitions– it stores the domain information that includes a computer, user, printer, group, etc. It also copies to all domain controllers in the domain.


24. What is a Proxy Server?

It is a computer that is actually a doorway between a local network (such as all computers in one organization or in a building) and a larger-scale system such as the Internet. Proxy servers offer increased security and performance. In most of the cases, they monitor employees using outside resources.

25. What is WINS server?

Windows Internet Name Service (WINS) servers map the IP addresses to NetBIOS names. This lets employers access resources by name of the computer rather than the IP address. To keep a check on the IP addresses and names of other computers network, this computer can be configured as a WINS server.

We may not able to connect to a remote network through its NetBIOS name, in case you are not using WINS in a network,

26. Define Dora Procedure & its usage.

Discover, request, Offer and acknowledgement. it is used to automatically allocate an IP address to systems of the client.

27. In which order the GPOs are applied?

We can apply the GPO is an order of

Local Group Policy object site,
Domain and
organizational units.
28. Can you state a few benefits of GPMC?

One of the major benefits of GPMC is its easy management of all GPOs diagonally the whole Active Directory Forest View of GPOs in one list. We can do the GPOs backup and restore, Immigration of GPOs across many forest and domains.

29. How you will do the backup for Group policy?

For back up, one single GPO, right-click the GPO and then click Back Up.
For backup, all GPOs in the domain, right-click Group Policy Objects and click Back Up All.
30. What is the group nesting?

When we add one group as an element of another group is known as ‘group nesting’. It also helps in easy management and reduced traffic replication.

31. What is Domain control?

A domain controller is a server that manages the security requests from other servers and computers in the Windows Server domain. There are two kinds of the domain controller that is a backup domain controller and a primary domain controller. The primary domain controller emphasis on services of the domain to avoid the system possibility of a crash or slowing down because of the overtasking from handling other security requests and functionality. If the primary domain controller goes down, a backup domain controller is promoted and become the primary domain controller to preserve the server systems working appropriately.

32. What is tree?

A tree is actually a collection of domains in the Active Directory that starts at one root and branches out into child domains, peripheral. This can similarly comprise an adjoining namespace linked in a transitive order. An Active Directory forest is an assortment of Active Directory trees, just like a real-world forest.
