XYZ company is moving its data services to azure as part of cloud adoption. Currently, there is data which is existing in the on-prem network. You are planning to use the HTTP connector method for copying this data.You plan to retrieve data from an HTTP/S endpoint by using the HTTP GET or POST methods. Which of the following options is best suited?

Answer options:

A.Self hosted Integration runtime with Azure Blob storage as sink
B.Self hosted Integration runtime with Azure Database for MariaDB as sink
C.Azure Integration runtime with Azure Blob storage as sink
D.Azure Integration runtimewith Azure Database for MariaDB as sink

Correct Answer: A
There are few main points in this question which we need to focus on to identify the exact answer. The first one is about the choice of connector used. The HTTP connect method is used here to copy data. Unlike Rest connector or Web Table connecter, it helps download data from any HTTP endpoint.Currently, Azure Database for MariaDB is not supported in the case of sink used, but Azure blob storage is supported. Secondly, the question says that the datastore is in the on-prem network. So, we will need a self-hosted integration runtime to connect to it.
Option A is correct: Azure blob storage is a supported sink, and Self-hosted integration runtime is required to connect data store in on-prem network.
Options B, C, D are incorrect: Azure Database for MariaDB is not a supported sink in the case of HTTP connecter. Azure integration runtime is wrong since it is used if the datastore is a managed cloud data service.
