Question # 1

An organization has created an API-led architecture that uses various API layers to integrate mobile clients with a backend system. The backend system consists of a number of specialized components and can be accessed via a REST API. The process and experience APIs share the same bounded-context model that is different from the backend data model. What additional canonical models, bounded-context models, or anti-corruption layers are best added to this architecture to help process data consumed from the backend system?

A. Create a bounded-context model for every layer and overlap them when the boundary contexts overlap, letting API developers know about the differences between upstream anddownstream data models 
B. Create a canonical model that combines the backend and API-led models to simplify and unify data models, and minimize data transformations. 
C. Create a bounded-context model for the system layer to closely match the backend data model, and add an anti-corruption layer to let the different bounded contexts cooperateacross the system and process layers 
D. Create an anti-corruption layer for every API to perform transformation for every data model to match each other, and let data simply travel between APIs to avoid the complexityand overhead of building canonical models

Question # 2

When designing an upstream API and its implementation, the development team has been advised to NOT set timeouts when invoking a downstream API, because that downstreamAPI has no SLA that can be relied upon. This is the only downstream API dependency of that upstream API. Assume the downstream API runs uninterrupted without crashing. What is the impact of this advice?

A. An SLA for the upstream API CANNOT be provided 
B. The invocation of the downstream API will run to completion without timing out 
C. A default timeout of 500 ms will automatically be applied by the Mule runtime in which the upstream API implementation executes 
D. A toad-dependent timeout of less than 1000 ms will be applied by the Mule runtime in which the downstream API implementation executes

Question # 7

A company requires Mule applications deployed to CloudHub to be isolated between nonproduction and production environments. This is so Mule applications deployed to nonproduction environments can only access backend systems running in their customerhosted non-production environment, and so Mule applications deployed to production environments can only access backend systems running in their customer-hosted production environment. How does MuleSoft recommend modifying Mule applications, configuring environments, or changing infrastructure to support this type of perenvironment isolation between Mule applications and backend systems?

A. Modify properties of Mule applications deployed to the production Anypoint Platform environments to prevent access from non-production Mule applications 
B. Configure firewall rules in the infrastructure inside each customer-hosted environment so that only IP addresses from the corresponding Anypoint Platform environments are allowedto communicate with corresponding backend systems 
C. Create non-production and production environments in different Anypoint Platform business groups 
D. Create separate Anypoint VPCs for non-production and production environments, then configure connections to the backend systems in the corresponding customer-hostedenvironments

Question # 15

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 olution 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?

A. se a CloudHub autoscaling policy to add CloudHub workers 
B. Use a CloudHub autoscaling policy to increase the size of the CloudHub worker 
C. Increase the size of the CloudHub worker(s)

Question # 30

A retail company is using an Order API to accept new orders. The Order API uses a JMS queue to submit orders to a backend order management service. The normal load for orders is being handled using two (2) CloudHub workers, each configured with 0.2 vCore. The CPU load of each CloudHub worker normally runs well below 70%. However, several times during the year the Order API gets four times (4x) the average number of orders. This causes the CloudHub worker CPU load to exceed 90% and the order submission time to exceed 30 seconds. The cause, however, is NOT the backend order management service, which still responds fast enough to meet the response SLA for the Order API. What is the MOST resource-efficient way to configure the Mule application's CloudHub deployment to help the company cope with this performance challenge?

A. Permanently increase the size of each of the two (2) CloudHub workers by at least four times (4x) to one (1) vCore 
B. Use a vertical CloudHub autoscaling policy that triggers on CPU utilization greater than 70% 
C. Permanently increase the number of CloudHub workers by four times (4x) to eight (8) CloudHub workers 
D. Use a horizontal CloudHub autoscaling policy that triggers on CPU utilization greater than 70%
