1. What is the different between Workgroup and Domain?
•Domain Server has Centralized Control   Where else Workgroup has no Centralized Control
•Domain Network has higher level of security when compared to Workgroup.
•Domain Network Implementation and Maintained cost is very less when compared to that of workgroup.
•Time constrain is very less when compared to that of a Workgroup.
•Administrator has overall control on the network where else workgroup has no control.

2. How will assign Local Administrator rights for domain user?
Navigate to Local User and Groups add the domain users to administrators group in the local system.

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.
10. What is the purpose of DHCP Server?
DHCP Server is used to assign IP address automatically to all the clients’ computers. It is useful in large enterprise network, where we may not able track the IP address and also used to avoid IP conflict.
11. Explain about Scope in DHCP Server?
Scope is collective information of assigning IP address for clients. It contains information like IP Address Range, Exclusion Range, Lease Period, Reservation, Router IP Address, DNS Address, etc. Based on the scope configuration DHCP allocates IP address to its entire client.
12. Explain about Group Scopes?
13. How will you backup DNS Server?
Backup the directory “%System Root%System32DNS”.
14. How will backup DHCP Server?

Alternate method: Open DHCP Console select server to backup and restore DHCP database.
15. Explain APIPA.
A Windows-based computer that is configured to use DHCP can automatically assign itself an Internet Protocol (IP) address if a DHCP server is not available or does not exist. The Internet Assigned Numbers Authority (IANA) has reserved for Automatic Private IP Addressing (APIPA).

17. Explain about Group Policy.
Group policies are used by administrators to configure and control user environment settings. Group Policy Objects (GPOs) are used to configure group policies which are applied to sites, domains, and organizational units (OUs) .There is a maximum of 1000 applicable group policies.
18. What is the default time for group policy refresh interval time?
The default refresh interval for policies is 90 minutes. The default refresh interval for domain controllers is 5 minutes. Group policy object’s group policy refresh intervals may be changed in the group policy object.
19. Explain Hidden Share.
Hidden or administrative shares are share names with a dollar sign ($) appended to their names. Administrative shares are usually created automatically for the root of each drive letter. They do not display in the network browse list.
