Internet Information Services (IIS) Interview Questions And Answers

There are different way to deploy the web application in
web server like
1- X Copy deployment
2- create setup package and install the server machine
3- use the deployment tools and configure the server
repositery and drag and drop all files in your machine to
virtul folder of server machine,

Yes, We can use multiple websites with same port number and
different IP address.

It depends upon the what kind of Application we are
using and related to frontend and backend features .Also
Number of hits to the server on live is one of the
Important key for the configuration .

Minimal configuration for a PHP webpage is

1.Any mid range server with (IBM system X , blade)
2.4 GB ram
3.160 GB HDD (May vary according to the Data )if seperate
DB server is used we dont want this much of space for the
Application server

Please be more specific on the Application we are going to
host , so that we can plan a good configuration .

If you are running your IIS server with 2 different versions of framework(1.1 & 2.0)you can create 2 different application pools and point your application to the required framework you want to run.

► Application pool is created the each and every website.
► Application domain is created to one domain purpose.

IIS 5.1 is for Windows XP
IIS 6 is for Windows Server, We can create separate application pool with worker process for a separete website in IIS 6.0 Server only.

The proporties of application Pool in IIS is:

1 Recycling
2 Performance
3 Health
4 Identity

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.

Yes, run ipv6.exe from command line to disable it.

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.

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

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.

IUSR_computername

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

Transport Layer Security (TLS) extends SSL by providing cryptographic authentication.

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.

On disk, as opposed to memory, as it used to be in IIS 5.

150-300 KB, 15-30% is a reasonable expectation.

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 hole into the search window.

Visual studio having It own ASP.NET Engine which is capable enough to run Asp.net web application from visual studio. So we just click on Run button to start the application.
Now this is the scenarios of local environment. But If we want to host it on server from where all user can access the sites then IIS comes into the picture.
IIS provides a redesigned WWW architecture that can help you achieve better performance, reliability, scalability, and security for our Web sites. IIS can support following Protocol HTTP/HTTPS, FTP, FTPS, SMTP Etc. We need to host the site on IIS, when request comes from client it first hits the IIS Server, then the server passed it to ASP.NET worker process to execute. Then the response also passes to client via IIS itself.
Note only Hosting of Site we can create our FTP Server, SMTP Server using IIS itself.
There are different version of IIS available like 5.1, 6.0, 7.0 etc.

Before answering this question you need to know what are the different IIS version is available in different OS. Below is the list of IIS version with different Operating system.
Windows Server 2008 - Windows Vista - Home Premium/ Ultimate - IIS 7.0
Windows Server 2003 - IIS 6.0
Windows XP Professional - IIS 5.1
Now based on your working experience you can say that you have worked on IIS 5.1 and 6.0 or only IIS 7. Etc.

Before Giving the Definition: you can say like this, Concept of Application pool has from IIS 6.0.
Application pools are used to separate sets of IIS worker processes that share the same configuration and application boundaries. Application pools used to isolate our web application for better security, reliability, and availability and performance and keep running with out impacting each other . The worker process serves as the process boundary that separates each application pool so that when one worker process or application is having an issue or recycles, other applications or worker processes are not affected.
One Application Pool can have multiple worker process Also.
Main Point to Remember:
★ Isolation of Different Web Application
★ Individual worker process for different web application
★ More reliably web application
★ Better Performance

Though we can create new application pool IIS with different settings, but IIS having its own default application pool named: DefaultAppPool.

Default Identity of IIS 6.0 is Network-Services.
Which is having very minimum rights on your system. The user can only have the read access of the site.
