Mulesoft MCPA-Level-1 Exam Questions

Several times a week, an API implementation shows several thousand requests per minute in an Anypoint Monitoring dashboard, Between these bursts, the dashboard shows between two and five requests per minute. The API implementation is running on Anypoint Runtime Fabric with two non-clustered replicas, reserved vCPU 1.0 and vCPU Limit 2.0.
An API consumer has complained about slow response time, and the dashboard shows the 99 percentile is greater than 120 seconds at the time of the complaint. It also shows greater than 90% CPU usage during these time periods.
In manual tests in the QA environment, the API consumer has consistently reproduced the slow response time and high CPU usage, and there were no other API requests at this time. In a brainstorming session, the engineering team has created several proposals to reduce the response time for requests.
Which proposal should be pursued first?

A. Increase the vCPU resources of the API implementation

B. Modify the API client to split the problematic request into smaller, less-demanding requests

C. Increase the number of replicas of the API implementation

D. Throttle the APT client to reduce the number of requests per minute

In an organization, the InfoSec team is investigating Anypoint Platform related data traffic. From where does most of the data available to Anypoint Platform for monitoring and alerting originate?

A.

From the Mule runtime or the API implementation, depending on the deployment model

B.

From various components of Anypoint Platform, such as the Shared Load Balancer, VPC, and Mule runtimes

C.

From the Mule runtime or the API Manager, depending on the type of data

D.

From the Mule runtime irrespective of the deployment model

An Order API triggers a sequence of other API calls to look up details of an order's items in a back-end inventory database. The Order API calls the OrderItems process API, which calls the Inventory system API. The Inventory system API performs database operations in the back-end inventory database.
The network connection between the Inventory system API and the database is known to be unreliable and hang at unpredictable times.
Where should a two-second timeout be configured in the API processing sequence so that the Order API never waits more than two seconds for a response from the Orderltems process API?

A. In the Orderltems process API implementation

B. In the Order API implementation

C. In the Inventory system API implementation

D. In the inventory database

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 and
downstream 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 cooperate
across 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 complexity
and overhead of building canonical models

A customer has an ELA contract with MuleSoft. An API deployed to CloudHub is consistently experiencing performance issues. Based on the root cause analysis, it is determined that autoscaling needs to be applied. How can this be achieved?

A. Configure a policy so that when the number of HTTP requests reaches a certain threshold the number of workers/replicas increases (horizontal scaling)

B. Configure two separate policies: When CPU and memory reach certain threshold, increase the worker/replica type (vertical sealing) and the number of workers/replicas (horizontal sealing)

C. Configure a policy based on CPU usage so that CloudHub auto-adjusts the number of workers/replicas (horizontal scaling)

D. Configure a policy so that when the response time reaches a certain threshold the worker/replica type increases (vertical scaling)

What is the main change to the IT operating model that MuleSoft recommends to
organizations to improve innovation and clock speed?

A.

Drive consumption as much as production of assets; this enables developers to discover
and reuse assets from other projects and encourages standardization

B.

Expose assets using a Master Data Management (MDM) system; this standardizes
projects and enables developers to quickly discover and reuse assets from other projects

C.

Implement SOA for reusable APIs to focus on production over consumption; this
standardizes on XML and WSDL formats to speed up decision making

D.

Create a lean and agile organization that makes many small decisions everyday; this
speeds up decision making and enables each line of business to take ownership of its
projects

4 Production environment is running on a dedicated Virtual Private Cloud (VPC) on CloudHub 1,0, and the security team guidelines clearly state no traffic on HTTP. Which two options support these security guidelines?

A. Option A

B. Option B

C. Option C

D. Option D

E. Option E

Say, there is a legacy CRM system called CRM-Z which is offering below functions:
1. Customer creation
2. Amend details of an existing customer
3. Retrieve details of a customer
4. Suspend a customer

A.

Implement a system API named customerManagement which has all the functionalities
wrapped in it as various operations/resources

B.

Implement different system APIs named createCustomer, amendCustomer,
retrieveCustomer and suspendCustomer as they are modular and has seperation of concerns

C.

Implement different system APIs named createCustomerInCRMZ,
amendCustomerInCRMZ, retrieveCustomerFromCRMZ and suspendCustomerInCRMZ as
they are modular and has seperation of concerns
