    2.     Difference between Everyone and Authenticated users?
    a.      Authenticated Users - Include all Users and Computers whose identities have been authenticated.
    b.     Everyone - For Windows 2003 and above, 'Everyone' includes all Authenticated Users including Guest accounts. Before Windows 2003, 'Everyone' includes all Authenticated Users , Guest accounts and Anonymous account.

    4.     What is an IP Helper address feature and why is it required in a DHCP environment ?
    a.      IP helper-address helps to implement DHCP relay agent in Cisco routers
    b.     This is configured at the network interface of the router containing the DHCP client
    c.      The IP helper-address intercepts the DHCP discover message from the client and unicasts it to the DHCP server after adding 'Option 82'.
    d.     With the help of Option 82, the DHCP server identifies the client network and assigns an IP from that network.
    5.     What is FRS and DFS-R ?
    a.      File Replication Service (FRS), introduced in Windows 2000 server to replicate DFS and Sysvol folder in DC. FRS is no longer used in new versions.
    b.     Distributed File System Replication (DFS-R), introduced in Windows 2008R2, came out as a replacement to FRS for replicating DFS and Sysvol.  
    6.     What is group policy preference ?

    8.     How to replace a failed RAID controller ?
    a.      This depends on the type of controller used. If you are using modern RAID controllers and are trying to replace with the same model, then the RAID should work without any issues as the RAID configuration or metadata is stored in the disk array. But you should ensure that you are using the same model from vendor or a model which is compatible with the failed controller.
    9.     What is the difference between RAID 1 and RAID 5 ?
    a.      RAID 1 - Mirroring - This RAID configuration gives you maximum redundancy as the same data is written into two disks at a time. But this solution will be costly as you always need to have disks double of what you actually require. Minimum 2 disks required.
    b.     RAID 5 - This RAID is the most popular RAID configuration. This works on the parity principle. Minimum 3 disks required. Even if one disk fail, the data of the failed disk can be calculated from the parity stored in the other 2 disks.
    10. In RAID 5, which activity is faster - Read or Write ?
    a.      Good Read performance but slower Write operations due to parity calculation.
