Q22. Difference between Mixed Mode and Native Mode?
A. There are two types of domain mode:
1. Mixed Mode: In this mode NT, win 2000 and win 2003 D.C. are available.
2. Native Mode: there are two types of native mode.
i. Win 2000 Native Mode: In this mode win 2000 and win 2003 DC are available.
ii. Win 2003 Native mode: in this mode only win 2003 DC are available.
Q23. What is SCSI?
A. SCSI stands for Small Computer System Interface. In SCSI the rate of data transmission is fast. SCSI Hard Disk Speed R.P.M. is fast in SCSI Data Transmission speed is 320 MBPS in the Network. In SCSI Controller We can connect Maximum 15 Physical Devices in the System.
Q24. What are A-Host Record and PTR Record?
A. A record is also called host record. This record is basically created in forward lookup Zone PTR record is also called a Pointer record. This record is basically created in reverse lookup Zone
Q25. What is reservation?

1. Class A - 0 - 126(127 is reserved for Loop back)
2. Class B - 128 – 191
3. Class C - 192 – 223
4. Class D - 224 - 239
5. Class E - 240 - 255
Q27. Difference between Hardware Router & Software Router?
A. Hardware Router: Hardware Router is a dedicated Router. It’s having a lot of feature such as Security, dedicated routing in the networking. As for Example Cisco Router.
Software Router: Software Router is not a dedicated router. It provides the different services also such as DNS Server, DHCP Server i.e. Windows Based Router.
Q28. Difference between Hardware Firewall and Software Firewall?
A. Hardware Firewall: It is a dedicated firewall. A lots of security features are available on hardware based firewall. As for Example- Cisco Pix Firewall.
Software Firewall: It is a dedicated firewall. It provides the normal security in the network- Check Point.
Q29. What is Domain Controller?
A. D.C. stands for Domain Controller. It provides the centralized management of entire domain in the network. When ever we will install active directory database on a server side operating system, then after that system becomes a D.C. Domain controller manages all security related interaction between users and computers in the network.
Q30. What is B Router?
A. B Router stands for Bridge Router. We can say this is a layer three bridge that provides the communication between two or
more different network ID.

1. Schema master
2. Domain Naming Master
3. RID Master
4. PDC Emulator
