7. What is DNS Server?
Domain Name System is used to resolve domain name to IP Address and also used to resolve IP Address to Domain Name. It has two zones Forward and Reverse Lookup Zone. Forward Lookup Zone resolve Domain name to IP address. Reverse Lookup Zone is used to resolve IP address to Domain Name. Some records associate with DNS
A Record binds Name with IP Address
- PTR Record binds IP Address to Name
8. Why DNS server is required for Active Directory?
The key reason for integrating DNS with AD is that client server communication takes place with Domain Name. Network needs IP address to reach the destination; In order to resolve Domain Name to IP Address we need DNS Server. If DNS Server is not configured properly the network becomes slow.
9. What is the Purpose of A and PTR Record?
- A Record OR Host Record is used to bind a Name with IP Address.
- PTR Record is used to bind an IP Address with Name.

30. Explain Quotas.
Disk Quota is a feature or service of NTFS which helps to restrict or manage the disk usage from the normal user. It can be implemented per user user per volume basis.By default it is disabled. Administrative privilege is required to perform the task. In 2003server we can control only drive but in 2008server we can establish quota in folder level.
31. Explain Backup Methodology.
The different types of backup methodologies are:
Normal Backup:-This is default backup in which all files are backed up even if it was backed up before.
Incremental Backup:-In this type of backup only the files that haven’t been backed up are taken care of or backed up.
Differential Backup:-This backup is similar to incremental backup because it does not take backup of those files backed up by normal backup but different from incremental because it will take backup of differentially backed up files at next time of differential backup.
System Backup:-This type of backup takes backup of files namely, Boot file, COM+Class Registry, Registry. But in server it takes backup of ADS.
ASR Backup:-This type of backup takes backup of entire boot partition including OS and user data. This should be the last troubleshooting method to recover an os from disaster.
32. Explain how to publish printer through AD.

44. How client server communication takes place in WSUS server?
Using Web Server or Web Services
45. What is the difference between Dynamic Disk and Basic Disk?
Basic Disk: Basic Disk uses a partition table to manage all partitions on the disk, and it is supported by DOS and all Windows versions. A disk with installed OS would be default initialized to a basic one. A basic disk contains basic volumes, such as primary partitions, extended partition, and all logical partitions are contained in extended partition.
Dynamic Disk: Dynamic Disk is supported in Windows 2000 and later operating system. Dynamic disks do not use a partition table to track all partitions, but use a hidden database (LDM) to track information about dynamic volumes or dynamic partitions on the disk. With dynamic disks you can create volumes that span multiple disks such as spanned and striped volumes, and can also create fault-tolerant volumes such as mirrored volumes and RAID 5 volumes. Compared to a Basic Disk, Dynamic Disk offers greater flexibility.
