MuleSoft Platform Architect (Mule-Arch-201) - Salesforce Exam Questions

An organization makes a strategic decision to move towards an IT operating model that emphasizes consumption of reusable IT assets using modern APIs (as defined by MuleSoft).

What best describes each modern API in relation to this new IT operating model?

Which of the following best fits the definition of API-led connectivity? A. B. C. layer based APIs API-led connectivity is not just an architecture or technology but also a way to organize people and processes for efficient IT delivery in the organization API-led connectivity is a 3-layered architecture covering Experience, Process and System layers API-led connectivity is a technology which enabled us to implement Experience, Process and System

A retail company with thousands of stores has an API to receive data about purchases and insert it into a single database. Each individual store sends a batch of purchase data to the API about every 30 minutes. The API implementation uses a database bulk insert command to submit all the purchase data to a database using a custom JDBC driver provided by a data analytics solution provider. The API implementation is deployed to a single CloudHub worker. The JDBC driver processes the data into a set of several temporary disk files on the CloudHub worker, and then the data is sent to an analytics engine using a proprietary protocol. This process usually takes less than a few minutes. Sometimes a request fails. In this case, the logs show a message from the JDBC driver indicating an out-of-file- space message. When the request is resubmitted, it is successful. What is the best way to try to resolve this throughput issue?

To minimize operation costs, a customer wants to use a CloudHub 1.0 solution. The customer's requirements are:

* Separate resources with two Business groups

* High-availability (HA) for all APIs

* Route traffic via Dedicated load balancer (DLBs)

* Separate environments into production and non-production

Which solution meets the customer's needs?

A set of tests must be performed prior to deploying API implementations to a staging environment. Due to data security and access restrictions, untested APIs cannot be granted access to the backend systems, so instead mocked data must be used for these tests. The amount of available mocked data and its contents is sufficient to entirely test the API implementations with no active connections to the backend systems. What type of tests should be used to incorporate this mocked data?
