Testlet 1
Topic 1, Scenario 1
Background
You are developing a flight information consolidation service. The service retrieves flight information 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.
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.
Business Requirements
A new data source for historical flight information is being developed by a contractor located on another continent.
If a time zone is not specified, then it should be interpreted as Coordinated Universal Time (UTC).
When you upgrade a service from a staging deployment to a production deployment, the time that the service is unavailable must be minimized.
The default port must be used for HTTP.
Technical Requirements
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 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 1.2.0.0. All assemblies provided by
Trey Research are 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.

QUESTION 1
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?
A. LINQ to XML
B. ADO.NET Entity Framework
C. ADO.NET DataSets
D. WCF Data Services
Correct Answer: D
Explanation

QUESTION 2
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?

QUESTION 3
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?
070-487

Correct 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 8
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.
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.

Question No : 19
You use a Microsoft SQL Server 2012 database that contains two tables named
SalesOrderHeader and SalesOrderDetail. The indexes on the tables are as shown in the
exhibit. (Click the Exhibit button.)
070-461
You write the following Transact-SQL query:
070-461
You discover that the performance of the query is slow. Analysis of the query plan shows
table scans where the estimated rows do not match the actual rows for SalesOrderHeader
by using an unexpected index on SalesOrderDetail.
You need to improve the performance of the query.
What should you do?
A. Use a FORCESCAN hint in the query.
B. Add a clustered index on SalesOrderId in SalesOrderHeader.
C. Use a FORCESEEK hint in the query.
D. Update statistics on SalesOrderId on both tables.
Answer: D
Explanation:

Question No : 20
Your database contains a table named Purchases. The table includes a DATETIME
column named PurchaseTime that stores the date and time each purchase is made. There
is a non-clustered index on the PurchaseTime column.
The business team wants a report that displays the total number of purchases made on the
current day.
You need to write a query that will return the correct results in the most efficient manner.
Which Transact-SQL query should you use?
A. SELECT COUNT(*)
FROM Purchases
WHERE PurchaseTime = CONVERT(DATE, GETDATE())
B. SELECT COUNT(*)
FROM Purchases
WHERE PurchaseTime = GETDATE()
C. SELECT COUNT(*) FROM Purchases
WHERE CONVERT(VARCHAR, PurchaseTime, 112) = CONVERT(VARCHAR,
GETDATE(), 112)
D. SELECT COUNT(*)
FROM Purchases
WHERE PurchaseTime >= CONVERT(DATE, GETDATE())
AND PurchaseTime < DATEADD(DAY, 1, CONVERT(DATE, GETDATE()))
Answer: D
Explanation:
Two answers will return the correct results (the “WHERE CONVERT…” and “WHERE …
AND … ” answers).
The correct answer for Microsoft would be the answer that is most “efficient”. Anybody
have a clue as to which is most efficient? In the execution plan, the one that I’ve selected
as the correct answer is the query with the shortest duration. Also, the query answer with
“WHERE CONVERT…” threw warnings in the execution plan…something about affecting
CardinalityEstimate and SeekPlan.
I also found this article, which leads me to believe that I have the correct answer:
