The existing sources of flight information and the mechanism of exchange are listed below.
Blue Yonder Airlines provides flight information in an XML file.
Consolidated Messenger provides flight information in a Microsoft http://www.passitdump.com/70-487.html Access database that is uploaded every 12 hours to the service using SFTP. The company uses port 22 for SFTP.
Margie’s Travel provides and consumes flight information using serialized ADO.NET DataSets. Data is periodically synced between the service and Margie’s Travel.
Trey Research provides data from multiple sources serialized in proprietary binary formats. The data must be read by using .NET assemblies provided by Trey Research. The assemblies use a common set of dependencies. The current version of the Trey Research assemblies is 220.127.116.11. All assemblies provided by Trey Research are 070-487 signed with a key pair contained in a file named Trey.snk, which Trey Research also supplies.
The application specification requires that any third-party assemblies must have strong names.
You are adding a new REST service endpoint to the FlightDataController controller that 070-487 returns the total number of seats for each airline.
You need to write a LINQ to Entities query to extract the required data.
Which code segment should you use?
Correct Answer: D
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?
A. Ensure that the EffectivePrivateBytesLimit value is greater than the size of the database file.
B. Change the sliding expiration of the cache item to 12 hours.
C. Use the SqlCacheDependency type configured with a connection string to the database file.
D. Use the CacheDependency type configured to monitor the SFTP target folder.
Correct Answer: D

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 070-487 historical flight information specify a set of airlines to search and whether the query should return only late flights. Results should be ordered by flight name.
You need to specify which properties of the FlightInfo class should be used at the partition and row 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.)
A. Use the WasLate property as the row key.
B. Use the Airline property as the row key.
C. Use the WasLate property as the partition key
D. Use the Arrival property as the row key.
E. Use the Airline property as the partition key.
F. Use the Flight property as the row key.
Correct Answer: BF
You are developing a flight information consolidation service. The service retrieves flight information 070-487 from a number of sources and combines them into a single data set. The consolidated flight information is stored in a SQL Server database. Customers can query and retrieve the data by using a REST API provided by the service.
Click here to learn more: http://www.passitdump.com/70-487.html The service also offers access to historical flight information. The historical flight information can be filtered and queried in an ad hoc manner.
The service runs on a Windows Azure Web Role. SSL is not used.
