Exam Certified Integration Architect topic 1 question 4 discussion

Actual exam question from Salesforce's Certified Integration Architect
Question #: 4
Topic #: 1
[All Certified Integration Architect Questions]

Universal Containers (UC) owns a variety of cloud-based applications, including Salesforce, alongside several on-premise applications. The on-premise applications are protected behind a corporate network with limited outside access to external systems.
UC would like to expose data from the on-premise applications to Salesforce for a more unified user experience. The data should be accessible from Salesforce in real time.
Which two actions should be recommended to fulfill this system requirement? (Choose two.)

  • A. Run a batch job with an extract, transform, load (ETL) tool from an on-premise server to move data to Salesforce.
  • B. Develop an application in Heroku that connects to the on-premise database via an Open Database Connectivity (ODBC) string and Virtual Private Cloud (VPC) connection.
  • C. Develop custom APIs on the company's network that are invokable by Salesforce.
  • D. Deploy MuleSoft to the on-premise network and design external facing APIs to expose the data.

B is incorrect because we are connecting to multiple applications. B assumes we are connecting to a database. C is obviously doable. My company did it recently with a named credential that had information to authorize against the APIs. People create APIs and expose them to Salesforce by use of a credential, all the time.

B is incorrect in my opinion: Why not? Heroku is not designed for real-time data access from on-premise sources. Heroku's VPC peering requires exposing the database, which may violate security policies. ODBC is not ideal for modern cloud integrations; APIs are the standard for real-time Salesforce data access. A is incorrect and kind obvious.

Ultimately, in order to connect to on-prem systems, you will require a virtual private cloud hosted by the customer, in order to transfer from an on-prem system to a cloud system. Salesforce will not be able to connect directly to any on-prem APIs (which is what option C is suggesting I assume).

Option B: This option is not recommended because developing an application in Heroku that connects to the on-premise database via an ODBC string and VPC connection would require significant development effort and may not provide real-time access to the data. Option C: This option is recommended because developing custom APIs on the company’s network that are invokable by Salesforce would allow Salesforce to access the on-premise data in real-time.

CD Requirment is RealTIme so A is wrong I think B is also wrong as Heroku will consume time to sync the data C: By using custom Sync Intgratio approach we can have realtime D: Muel Soft supports for real time integration C:
