Mulesoft MCPA-Level-1 Exam Questions

A Rate Limiting policy is applied to an API implementation to protect the back-end system. Recently, there have been surges in demand that cause some API client POST requests to the API implementation to be rejected with policy-related errors, causing delays and complications to the API clients. How should the API policies that are applied to the API implementation be changed to reduce the frequency of errors returned to API clients, while still protecting the back-end system?

A. Keep the Rate Limiting policy and add 9 Client ID Enforcement policy

B. Remove the Rate Limiting policy and add an HTTP Caching policy

C. Remove the Rate Limiting policy and add a Spike Control policy

D. Keep the Rate Limiting policy and add an SLA-based Spike Control policy

Mule applications that implement a number of REST APIs are deployed to their own subnet
that is inaccessible from outside the organization.
External business-partners need to access these APIs, which are only allowed to be
invoked from a separate subnet dedicated to partners - called Partner-subnet. This subnet
is accessible from the public internet, which allows these external partners to reach it.
Anypoint Platform and Mule runtimes are already deployed in Partner-subnet. These Mule
runtimes can already access the APIs.
What is the most resource-efficient solution to comply with these requirements, while
having the least impact on other applications that are currently using the APIs?

A.

Implement (or generate) an API proxy Mule application for each of the APIs, then deploy the API proxies to the Mule runtimes

B.

Redeploy the API implementations to the same servers running the Mule runtimes

C.

Add an additional endpoint to each API for partner-enablement consumption

D.

Duplicate the APIs as Mule applications, then deploy them to the Mule runtimes

An organization has implemented a Customer Address API to retrieve customer address
information. This API has been deployed to multiple environments and has been configured
to enforce client IDs everywhere.
A developer is writing a client application to allow a user to update their address. The
developer has found the Customer Address API in Anypoint Exchange and wants to use it
in their client application.
What step of gaining access to the API can be performed automatically by Anypoint
Platform?

A.

Approve the client application request for the chosen SLA tier

B.

Request access to the appropriate API Instances deployed to multiple environments using the client application's credentials

C.

Modify the client application to call the API using the client application's credentials

D.

Create a new application in Anypoint Exchange for requesting access to the API

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?

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)

D.

Increase the number of CloudHub workers

2. LOB IT owns and focuses on Process Layer APIs
3. Central IT owns and focuses on System Layer APIs

A business process is being implemented within an organization's application network. The architecture group proposes using a more coarse-grained application network design with relatively fewer APIs deployed to the application network compared to a more fine-grained design. Overall, which factor typically increases with a more coarse-grained design for this business process implementation and deployment compared with using a more finegrained design?

A. The complexity of each API implementation

B. The number of discoverable assets related to APIs deployed in the application network

C. The number of possible connections between API implementations in the application network

D. The usage of network infrastructure resources by the application network

Refer to the exhibit.

A.

Option A

B.

Option B
