HOTSPOT
You are supporting an application that uses the ADO.NET Entity Framework to query and access data. The
latest version of Entity Framework contains bug fixes that will improve performance. You need to update Entity
Framework. Which Visual Studio 2012 menu item should you choose? (To answer, select the appropriate
menu item in the answer area.)

You are developing an ASP.NET MVC application. Deployment administrators do not have access to Visual
Studio 2012, but will have the elevated permissionsrequired to deploy the application to the servers.You need
to select a deployment tool for use by the deployment administrators. Which tool should you use?

You need to recommend a data access technology to the contractor to retrieve data from the new data source.
Which data access technology should you recommend?

Errors occasionally occur when saving data using the FlightInfoContext ADO.NET Entity Framework context.
Updates to the data are being lost when an error occurs. You need to ensure that data is still saved when an
error occurs by retrying the operation. No more than five retries should be performed. Which code segment
should you use as the body of the SaveChanges() method in the FlightInfoContext.es file?

You are adding a new REST service endpoint to the FlightDataController controller. It returns flights from the
consolidated data sources only for flights that arelate. You need to write a LINQ to Entities query to extract the
required data. Which code segment should you use?

Data provided by Consolidated Messenger is cached in the HttpContext.Cache object. You need to ensure that
the cache is correctly updated when new data arrives. What should you do?

You need to load flight information provided by Consolidated Messenger. Which should you use?

You are adding a new REST service endpoint to the FlightDataController controller that returns the total number
of seats for each airline. You need to write a LINQto Entities query to extract the required data.
Which code segment should you use?

You need to load flight information provided by Consolidated Messenger. What should you use?

Historical flight information data will be stored in Windows Azure Table Storage using the FlightInfo class as the
table entity. There are millions of entries in the table. Queries for historical flight information specify a set of
airlines to search and whether the query should return only late flights. Results should be ordered byflight
name. You need to specify which properties of the FlightInfo class should be used at the partition androw keys
to ensure that query results are returned as quickly as possible. What should you do? (Each correct answer
presents part of the solution. Choose all that apply.)
