Latest Windows Server Administrator Interview Questions and Answers 1) Differentiate between NTFS & FAT.NTFS is the current file system used by Windows. It offers features like security permissions (tolimit other users’ access to folders), quotas (so one user can’t fill up the disk), shadowing (backingup) and many other features that help Windows.FAT32 is the older Microsoft filesystem, primarily used by the Windows 9X line and Window could beinstalled on a FAT32 parition up to XP. In comparision, FAT32 offers none of what was mentionedabove, and also has a maximum FILE (not folder) size of 4GB, which is kind of small these days,especially in regards to HD video.2) What Is VOIP.VOIP Short for Voice Over Internet Protocol, a category of hardware and software that enablespeople to use the Internet as the transmission medium for telephone calls by sending voice data inpackets using IP rather than by traditional circuit transmissions.3) What is loop back.Loopback address is 127.0.0.1,An address that sends outgoing signals back to the same computer for testing.4) What is Proxy Server.A proxy server is a computer that acts as a gateway between a local network (e.g., all the computersat one company or in one building) and a largerscale network such as the Internet. Proxy serversprovide increased performance and security.

Your computer may bestandalone or part of network or connected to Internet you need an antivirus program. It activelymonitors when you are using your system for any virus threat from different sources. if it found oneit tries to clean or quarantine the virus ultimately keeping your system and data safe.Firewall:Firewall is in other hand a program which protects your system from outsider/intruder/hackerattacks. These attacks may not be virus type. In some cases hackers can take control of your systemremotely and steal your data or important information from system. If your system is directlyconnected to internet or a large network than you can install a software firewall in your PC to protect your self from unauthorized access.

For asingle PC you may need a software firewall while a large corporate implements hardware firewall toprotect all of their systems from such attacks.6) Differentiate between Frond end & Back End Server.Backend server:A back end server is a computer resource that has not been exposed to the internet. In this regardthe computing resource does not directly interact with the internet user. It can also be described asa server whose main function is to store and retrieve email messages.Frontend server:A frontend server is a computer resources that has exposed to the internet.7) What is APIPA.Stands for Automatic Private IP AddressingAPIPA is a DHCP fail over mechanism for local networks. With APIPA, DHCP clients can obtain IPaddresses when DHCP servers are nonfunctional.APIPA exists in all modern versions of Windows except Windows NT.When a DHCP server fails, APIPA allocates IP addresses in the private range 169.254.0.1 to169.254.255.254.8) How Release and renew IP address from Command prompt.Ipconfig / releaseipconfig / renew9) What is wins server.Windows Internet Name Service (WINS) servers dynamically map IP addresses to computer names(NetBIOS names). This allows users to access resources by computer name instead of by IP address.If you want this computer to keep track of the names and IP addresses of other computers in yournetwork, configure this computer as a WINS server.If you do not use WINS in such a network, you cannot connect to a remote network resource byusing its NetBIOS name.10)What is the Windows Registry.The Windows Registry, usually referred to as “the registry,” is a collection of databases ofconfiguration settings in Microsoft Windows operating systems Latest Windows Server Administrator Interview Questions and Answers 11) System Volume Information (SVI) Folder.Windows XP includes a folder named System Volume Information on the root of each drive thatremains hidden from view even when you choose to show system files.

SATA stands for Serial Advanced Technology Attachment (or Serial ATA)and IDE is also called Parallel ATA or PATA. SATA is the newer standard and SATA drives are fasterthan PATA (IDE) drives. For many years ATA provided the most common and the least expensiveinterface for this application. But by the beginning of 2007, SATA had largely replaced IDE in allnew systems.15)Main Difference Between Windows server 2008 and 20121) New Server Manager: Create, Manage Server Groups2) HyperV Replication : The HyperV Replica feature allows you to replicate a virtual machine fromone location to another with HyperV and a network connection—and without any shared storagerequired.

If it exists in local DNS cache, it uses that information.Otherwise, DNS querying is performed until the IP address is found.Then, your browser opens a TCP connection to the destination host and sends the request according toHTTP 1.1 (or might use HTTP 1.0, but normal browsers don’t do it any more).The server looks up the required resource (if it exists) and responds using HTTP protocol, sends the datato the client (=your browser)The browser then uses HTML parser to recreate document structure which is later presented to you onscreen. If it finds references to external resources, such as pictures, css files, javascript files, these areis delivered the same way as the HTML document itself.
