Ensurepass 2018 PDF and VCE

Some airlines do not specify the timezone of the arrival time. If the timezone is not specified, then it should be interpreted per the business requirements.

You need to implement the LoadFlights() and Parse() methods of the BlueYonderLoader class.

What should you do? (To answer, drag the appropriate code segments to the correct location in the answer area. Each segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

Question No: 145 – (Topic 5)

You are adding a new REST service endpoint to the FlightDataController controller. It

returns flights from the consolidated data sources only for flights that are late. You need to write a LINQ to Entities query to extract the required data.

Which code segment should you use?

  1. Option A

  2. Option B

  3. Option C

  4. Option D

Answer: D

Explanation: Explanation/Reference:

D is right because you send result as REST so if you use “AsQueryable” the result is deferred to the next enumeration of your result.

D is not optimized but will works. A will break at runtime.

Question No: 146 – (Topic 5)

Transformed historical flight information provided by the RemoteDataStream() method

must be written to the response stream as a series of XML elements named Flight within a root element named Flights. Each Flight element has a child element named FlightName that contains the flight name that starts with the two-letter airline prefix.

You need to implement the StreamHistoricalFlights() method so that it minimizes the amount of memory allocated.

Which code segment should you use as the body of the StreamHistoricalFlights() method in the HistoricalDataLoader.es file?

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 by flight name.

What should you do? (To answer, drag the appropriate properties to the correct location or locations in the answer area. Each property may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)
