3.Q: What is the use for DHCP?
A: DHCP is used for the DHCP servers, personal computers can get their configuration from a DHCP server on an IP configuration. The server knows nothing about the personal computers until they make a request for information. Usually the most common information sent is IP address and DHCP is used to make a large network administration easier.
4.Q: What does a Super Scope do in DHCP?
A: The Super Scope gives the DHCP server the possibility to have leases to multiple clients on the same physical network. The leases come from multiple scopes. All scopes must be defined using DHCP manager before the Super Scope creation and they are named member scopes. The DHCP problems can be resolved by the Super Scope in different ways like the following:
a) on a physical network like a LAN network where multiple logical IP networks exist Super Scope is very useful here. These types of networks are also named multinets.
b) there is also need for a Super Scope when the address pool for the current scope becomes empty and there is a need for new computers on the physical network.
c) when clients have to move on another scope.
d) when DHCP clients from the other side of the relay agents (BOOTP) or the network has many logical subnets.
e) when standard networks are limited to leasing addresses for the clients.
5.Q: How can we switch the roles in an Active Directory?
A: Switching or transferring roles in an Active Directory can be made with the use of Ntdsutil.exe.
6.Q: What is the purpose of a Stub zone DNS?
A: The copy of a zone that has only the needed resources for finding the authoritative DNS servers in that specific zone (DNS= Domain Name Servers) is called a Stub zone. It also resolves names for DNS namespaces, thing required when names must be resolved from two different DNS namespaces. The Stub zone contains: the master server’s IP that is used for updating the Stub zone and the SOA (Start of Authority), the NS (name server) and the glue A delegated zone records.
5.Q: What main file is used for Active Directory backup and how it is made?
A: Active Directory backup is made using NTbackup utility. The backup is made once with the system state and they are restored also together because they depend on each other. The system state has different components like:
a) The registry
b) Boot files or startup files (files required by the operating system to start).
c) The component services
d) The system volume or the SYSVOL folder this is a folder that contains files that are shared on a domain.
e) The Active Directory

A: Yes and I can explain how. A system administrator is responsible for an entire network which means he/she must take care of multiple things in the same time which is not an easy task. In order to achieve this, an administrator must have high organization skills and a high technical knowledge and he/she must prevent the problems from happening so that he/she won’t have to be forced to fix them.

19.Q: When is a good time for creating a forest?
A: Certain companies that have different bases require different trees and separate namespaces. And unique names sometimes give birth to different identities of DNS. Also companies are sometimes acquired and get under other influences but the continuity must be preserved for the names.
20.Q: Can you explain to us about you experience in the past regarding windows administration?
A: I have ten years of experience in this field, I was passionate about computers since childhood and I installed many operating systems at home and inside organizations including these versions of windows: 95, 98, 98 SE, NT, Millenium, 2000, 2003 Server, XP, Seven, Vista.

A: In this situation the application has to be started in the compatibility mode with a previously windows operating system. This is made by right clicking the application icon and choosing another Windows from the compatibility menu.
22.Q: What is the meaning of Repadmin.exe from Windows Server 2008?
A: Repadmin.exe means Replication Diagnostics Tool and helps for the diagnostic of domain controllers in the Windows system. This tool is used by administrators to see the replication topology from the perspective of every domain controller. The active Directory forest can also be supervised by Repadmin.exe and replication problems can be tracked.
23.Q: What difference can we find in the usage of CSVDE versus LDIFDE?
A: CSVDE and LDIFDE are both commands and are used for importing and exporting objects but they are different in the way that CSVDE uses the format CSV (Comma Separated Value) which is an Excel file for files and LDIFDE uses LDIF (LDAP Data Interchange Format) file type which can be viewed with a simple text editor. LDIFDE can be also used for editing or deleting objects unlike CSVDE.
24.Q: What big differences exist between these two operating systems: Windows 2000 and Windows XP?
A: Windows 2000 has more capabilities than Windows XP especially regarding features like DHCP, Terminal Services or DNS. It has all the advantages for server usage. Windows 2000 is a little more professional than XP, but they are both coming with different versions for every user taste. While XP has Home version, Professional or Enterprise, Windows 2000 has Professional and Server editions. The Home version of XP comes with minimal features because the target clients are beginners.
25.Q: What are the things that make Unix different from Windows?
A: The code loading runtime of Unix is different from the one that Windows has. We must become aware of how the system exactly works before we make a dynamically loading module. Unix has the shared objects with the .so extension that encapsulate lines of code that the programs will use and the functions names. These function names become the references of those functions in the memory of the program when the file is combined with the program. In Windows the .dll file (dynamic-link library file) doesn’t have references and the code of the files does not link to the memory of the program but they get through a lookup table which points to data or functions. Unix has just one type of library file, with the .a extension and the code of many object file is contained within with the .o extension. When the link is created for a shared object file the definition of the identifier may not be found, so the object code from the library will be included.
