.What is presentation layer responsible for in the OSI model?
The presentation layer establishes the data format prior to passing it along to the network application’s interface. TCP/IP networks perform this task at the application layer.

Does Windows Server 2003 support IPv6?
Yes, run ipv6.exe from command line to disable it.

Can Windows Server 2003 function as a bridge?
Yes, and it’s a new feature for the 2003 product. You can combine several networks and devices connected via several adapters by enabling IP routing.

What’s the difference between the basic disk and dynamic disk?

The basic type contains partitions, extended partitions, logical drivers, and an assortment of static volumes; the dynamic type does not use partitions but dynamically manages volumes and provides advanced storage options

What’s a media pool?
It is any compilation of disks or tapes with the same administrative properties.

How do you install recovery console?

C:\i386\win32 /cmdcons, assuming that your Win server installation is on drive C.

What’s new in Terminal Services for Windows 2003 Server?
Supports audio transmissions as well, although prepare for heavy network load.

What scripts ship with IIS 6.0?
iisweb.vsb to create, delete, start, stop, and list Web sites, iisftp.vsb to create, delete, start, stop, and list FTP sites, iisdir.vsb to create, delete, start, stop, and display virtual directories, iisftpdr.vsb to create, delete, start, stop, and display virtual directories under an FTP root, iiscnfg.vbs to export and import IIS configuration to an XML file.

What secure authentication and encryption mechanisms are supported by IIS 6.0?
Basic authentication, Digest authentication, Advanced digest authentication, Certificate-based Web transactions that use PKCS #7/PKCS #10, Fortezza, SSL, Server-Gated Cryptography, Transport Layer Security

What’s the relation between SSL and TLS?
Transport Layer Security (TLS) extends SSL by providing cryptographic authentication.

What’s the role of http.sys in IIS?

It is the point of contact for all incoming HTTP requests. It listens for requests and queues them until they are all processed, no more queues are available, or the Web server is shut down.

Where’s ASP cache located on IIS 6.0?
On disk, as opposed to memory, as it used to be in IIS 5.

What is socket pooling?
Non-blocking socket usage, introduced in IIS 6.0. More than one application can use a given socket.

Describe the process of clustering with Windows 2003 Server when a new node is added?
As a node goes online, it searches for other nodes to join by polling the designated internal network. In this way, all nodes are notified of the new node’s existence. If other nodes cannot be found on a preexisting cluster, the new node takes control of the quorum resources residing on the shared disk that contains state and configuration data.

What applications are not capable of performing in Windows 2003 Server clusters?
The ones written exclusively for NetBEUI and IPX.

What’s a heartbeat?
Communication processes between the nodes designed to ensure node’s health.

What’s a threshold in clustered environment?
The number of times a restart is attempted, when the node fails.

You need to change and admin password on a clustered Windows box, but that requires rebooting the cluster, doesn’t it?
No, it doesn’t. In 2003 environment you can do that via cluster.exe utility which does not require rebooting the entire cluster.

For the document of size 1 MB, what size would you expect the index to be with Indexing Service?
150-300 KB, 15-30% is a reasonable expectation.

Doesn’t the Indexing Service introduce a security flaw when allowing access to the index?
No, because users can only view the indices of documents and folders that they have permissions for.

What’s the typical size of the index?
Less then 100K documents - up to 128 MB. More than that - 256+ MB.

How would you search for C++?
Just enter C++, since + is not a special character (and neither is C).

What about Barnes&Noble?
Should be searched for as Barnes’&’Noble.

What’s a vector space query?
A multiple-word query where the weight can be assigned to each of the search words. For example, if you want to fight information on ‘black hole’, but would prefer to give more weight to the word hole, you can enter black[1] hole[20] into the search window.

What is Virtual Memory?
Virtual memory is a technique that allows the execution of processes that may not be completely in memory. A separation of user logical memory from physical memory allows an extremely large virtual memory to be provided for programmers when only a smaller physical memory is available. It is commonly implemented by demand paging. A demand paging system is similar to a paging system with swapping. Processes reside on secondary memory (which is usually a disk). When we want to execute a process, we swap it into memory.

In the TCP client-servel model, how does the three-way handshake work in opening connection?
The client first sends a packet with sequence "x" to the server. When the server receives this packet, the server will send back another packet with sequence "y", acknowledging the request of the client. When the client receives the acknowledgement from the server, the client will then send an acknowledge back to the server for acknowledging that sequence "y" has been received.
What is a router? What is a gateway?
Routers are machines that direct a packet through the maze of networks that stand between its source and destination. Normally a router is used for internal networks while a gateway acts a door for the packet to reach the ‘outside’ of the internal network
