You are designing a Universal Windows Platform (UWP) app that will access external data sources. The data sources have the following requirements:
• The data must be stored in a relational database.
• The data sources must be stored in a public cloud.
• The app must not connect directly to the database.
• The app must access the data sources by using HTTP verbs.
You need to identify the appropriate data storage type and the appropriate method to use to access the data sources.
What should you identify? Select two.
A.
Data storage type: SQL Server
B.
Data storage type: SQL Azure
C.
Data storage type: Oracle Data Provider
D.
Data storage type: XML
E.
Data access method: ASMX Services
F.
Data access method: WCF Services
G.
Data access method: OData
H.
Data access method: JSON
Explanation:
OData is the built-in data access protocol for tables in Microsoft’s Windows Azure, and it’s supported for access to relational data in SQL Azure as well. OData
provides an abstract data model. An OData client accesses data provided by an OData service using standard HTTP. The OData protocol largely follows the
conventions defined by REST, which define how HTTP verbs are used. OData is being used to expose data from a variety of sources, from relational databases like
SQL Azure and file systems to content management systems and traditional websites.https://msdn.microsoft.com/en-us/data/hh237663.aspx
