o            How is security managed in SharePoint?


Sharepoint using three types of user authentications. There are Windows, Form and Single Sign On.

Security Socket Layer (SSL) is also used for authentication in Sharepoint. Authorization, Authentication and Impersonation these are configured by config file.


o            How are web parts developed?


WebParts developed by using Visual Studio .Net 2005. It offers many Sharepoint templates like Site Definition, Web Part etc. And also using Widows Class Library.


o            What is a site definition?


A Site Definition is a group of files that used to define a unique type of Sharepoint Site. Example, one site definition defines the Team Site, Blank Site, and Document Workspace templates, and another site definition defines the Basic Meeting Workspace, Blank Meeting Workspace, Decision Meeting Workspace, Social Meeting Workspace, and Multipage Meeting Workspace templates.

Yes. Two web parts has sharing information in a runtime. We use the Connection Interfaces to create Connectable Web parts.


o            What is a personal view and what is a shared view?


A Web Part page view has two views. There are Personal view and Shared View.


Personal View: This view is set by each user. For example, one user has changed the list in some format. The changes will not see the other users.


Shared View: This view web part designs and any thing is not changed by users. Users will not be changed these types of web parts. The site admin can change the web part view and anything


o            What is an STP file?


STP means Site Template. We can create new site definition. This definition has webparts and list (there are derived from default Sharepoint components). We can save the file for .stp format.

o            How can you extend lists in SharePoint?


We expand the size of the lists. Click Start, point to All Programs, point to Administrative Tools, and then click SharePoint Central Administration.




o            Explain the document versioning in SharePoint document libraries


We can maintain version in all Sharepoint libraries and lists.  When we upload or update any document, while Sharepoint creates version.

o            Where is web part resources contained?


The WebPart resources can not part of the DLL, because there are used in url based. Like images, jscript files. The WebPart is installed in GAC and Bin directory.

  • We use GAC
  • We develop web part in Windows Class Library. While the web part once runs, it will install automatically in GAC.

o     What are the archiving strategies?


o     Describe the search strategies?          Enterprise search tools help organizations (including small and mid-size businesses—not just enterprises) find information in text documents and other unstructured data stored in a variety of sources. In general, enterprise search tools can be used to search internal data sources (such as intranets, messaging systems, file shares, databases, and local hard drives) and Web sites (public or controlled-access), but many solutions are focused on only one of the two scenarios.

Enterprise search is similar to Internet search, which is supported by the public Google Web site, MSN Search, and other providers. In both types of search, material must be aggregated from a wide variety of locations, users must have an interface to create queries and review results, and results should be arranged in some kind of order (e.g., hits that are most relevant to the query appear at the top of the list).

One critical difference between enterprise and Internet search tools is the scope of material aggregated. Internet search tools attempt to catalog as many public sources as possible but make little effort to catalog material stored behind firewalls, in databases, or on controlled-access Web sites. Enterprise search tools don’t need to catalog as many sources of data but must aggregate more types of data and provide access control, so that sensitive information is unavailable to unauthorized viewers.

In addition, algorithms that work well on Internet search may not work as well for enterprise search—for instance, Google’s PageRank system, which rates relevance partly based on how many other Web pages link to a particular page, is not as effective in a corporate environment where hyperlinking among resources is less common. As a consequence, enterprise search tools use algorithms different from Internet search tools.

In addition, enterprise search tools generally let the data owner exercise some programmable control over the results, such as the following:

  • Creating multiple data catalogs and letting the user specify which to search
  • Manually selecting or influencing search results (e.g., selecting particular sources to appear at the top of the list for particular queries; tweaking the algorithms used to determine relevance)
  • Enabling attributes (e.g., date, author) to be assigned to content sources in a systematic way so that searches can consider these attributes and arrange results accordingly.

Today, dozens of enterprise search tools are available, from free open-source tools that perform a single function (usually public Web site search) to costly installations from companies such as Autonomy and Verity. IBM and Oracle offer intranet search as part of larger solutions incorporating data storage, and a growing number of companies are offering software (Fast Search and Transfer, MondoSoft) or hosted services (Atomz) specifically for Web site search. Finally, although Google is best known for Internet search, it also offers search appliances ranging in price from US$5,000 to US$250,000 or more that can be used for both intranet and Web site search.


o     Can you implement forms-based authentication with SharePoint?


Yes. We can implement forms-based authentication with SharePoint.


o    Describe how single sign-on works

   Easily maintain Role and group users’ information in one place.

A while back, I posted a list of ASP.NET Interview Questions. Conventional wisdom was split, with about half the folks saying I was nuts and that it was a list of trivia. The others said basically “Ya, those are good. I’d probably have to look a few up.” To me, that’s the right response.

Certainly I wasn’t trying to boil all of .NET Software Development down to a few simple “trivia” questions. However, I WAS trying to get folks thinking. I believe that really good ASP.NET (and for that matter, WinForms) is a little [read: lot] more than just draging a control onto a designer and hoping for the best. A good race driver knows his car – what it can do and what it can’t.

So, here’s another list…a greatly expanded list, for your consumption (with attribution). I wrote this on a plane last week on the way from Boise to Portland. I tried to take into consideration the concerns that my lists contain unreasonable trivia. I tried to make a list that was organized by section. If you’ve never down ASP.NET, you obviously won’t know all the ASP.NET section. If you’re an indenpendant consultant, you may never come upon some of these concepts. However, ever question here has come up more than once in the last 4 years of my time at Corillian. So, knowing groking these questions may not make you a good or bad developer, but it WILL save you time when problems arise.
