You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create a WindowsCommunication Foundation (WCF) Data Services service. You discover that when anapplication submits a PUT or DELETE request to the Data Services service, it receives an error. You need to ensure that the application can access the service. Which header and request type should you use in the application?
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create anapplication. The application uses the ADO.NET Entity Framework to model entities. Theapplication allows users to make changes to entities while disconnected from the central data store. You need to ensure that when the user connects to the central data store and retrieves new data, the application meets the following requirements:
  • Changes made to the local data store in disconnected mode are preserved.
  • Entities that have already been loaded into the local data store, but have not been modified by the user, are updated with the latest data.

Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.
When using ODBC, which of the following processes ODBC requests and submits specific SQL statements to a given type of data source?
You develop an enterprise application, called XYZApplication that includes a Windows Form presentation layer, middle-tier components for business logic and data access, and a Microsoft SQL Server database.
You are in the process of creating a middle-tier component that will execute the data access routines in your application. When data is passed to this component, the component will call several SQL Server stored procedures to perform database updates. All of these procedure calls run under the control of a single transaction.
The code for the middle-tier component will implement the following objects:
SqlConnection cn = new SqlConnection();
SqlTransaction tr;
If two users try to update the same data concurrently, inconsistencies such as phantom reads will occur. You must now add code to your component to specify the highest possible level of protection against such inconsistencies.

Jio is a big shot at reducing the cost of Internet access in India. The U.S., despite being the richest country in the world, lags far behind in terms of cost and penetration of Internet access. Cheap access to the Internet is an important step in bridging the access gap – access to good education, good healthcare, etc. But the market reaction to Jio is similar to the U.S. markets reaction to firms announcing their intention to diversify. (A)The final group of losers is the current shareholders of RIL. On announcement of Jio, the stock price of RIL fell. (B) It shows that the markets short-term reaction is usually proven correct in the long-run. (C) On losing end, the first groups of losers are the shareholders of other telecom companies. (D)The large amount of revenue the Government of India gets from auctioning off the nations natural resources is not necessarily a good thing because the Government does not have a stellar track record when it comes to spending the money. A large fraction of Government spending is wasted. (E) The second loser is the Government of India. The big money the Indian Government was raking in selling cellular bandwidth was actually coming from the pockets of the cellular consumers. (F)The first obvious winners of this scheme are customers. (G) The second winner is Mr. Ambani; he can potentially make a lasting impact as the man who brought Internet to millions of Indians. Question: Which of the following supports the decision of other companies opposing Reliance JIO Scheme?
An application that uses the ODBC interface could process any database that is ODBC-compliant without any program coding changes.
