Salesforce Exam Integration Architect Topic 9 Question 21 Discussion

business requires automating the check and update of the phone number type

classification (mobile vs. landline) for all in-coming calls delivered to their phone

sales agents. The following conditions exist:

1. At peak, their call center can receive up to 100,000 calls per day.

2. The phone number type classification is a service provided by an external service API.

3. Business is flexible with timing and frequency to check and update the records (throughout

the night or every 6-12 hours is sufficient).

A Remote-Call-In pattern and/or Batch Synchronization (Replication via ETL: System ->

Salesforce) are determined to work with a middleware hosted on custom premise.

In order to implement these patterns and mechanisms, which component should an integration architect recommend?
