Mulesoft MCPA-Level-1 Exam Questions

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. One production and one non-production Virtual Private Cloud (VPC).
Use availability zones to differentiate between Business groups.
Allocate maximum CIDR per VPCs to ensure HA across availability zones

B. One production and one non-production Virtual Private Cloud (VPC) per Business group.
Minimize CIDR aligning with projected application total.
Choose a MuleSoft CloudHub 1.0 region with multiple availability zones.
Deploy multiple workers for HA,

C. One production and one non-production Virtual Private Cloud (VPC) per Business group.
Minimize CIDR aligning with projected application total.
Divide availability zones during deployment of APIs for HA.

D. One production and one non-production Virtual Private Claud (VPC).
Configure subnet to differentiate between business groups.
Allocate maximum CIDR per VPCs to make it easier to add Child groups.
Span VPC to cover three availability zones.

An organization wants to make sure only known partners can invoke the organization's
APIs. To achieve this security goal, the organization wants to enforce a Client ID
Enforcement policy in API Manager so that only registered partner applications can invoke
the organization's APIs. In what type of API implementation does MuleSoft recommend
adding an API proxy to enforce the Client ID Enforcement policy, rather than embedding
the policy directly in the application's JVM?

A.

A Mule 3 application using APIkit

B.

A Mule 3 or Mule 4 application modified with custom Java code

C.

A Mule 4 application with an API specification

D.

A Non-Mule application

An application updates an inventory running only one process at any given time to keep the inventory consistent. This process takes 200 milliseconds (.2 seconds) to execute; therefore, the scalability threshold of the application is five requests per second. What is the impact on the application if horizontal scaling is applied, thereby increasing the number of Mule workers?

A. The application scalability threshold is five requests per second regardless of the horizontal scaling

B. The total process execution time is now 100 milliseconds (.1 seconds)

C. The application scalability threshold is now 10 requests per second

D. Horizontal scaling cannot be applied to an already-running application

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

When using CloudHub with the Shared Load Balancer, what is managed EXCLUSIVELY
by the API implementation (the Mule application) and NOT by Anypoint Platform?

A.

The assignment of each HTTP request to a particular CloudHub worker

B.

The logging configuration that enables log entries to be visible in Runtime Manager

C.

The SSL certificates used by the API implementation to expose HTTPS endpoints

D.

The number of DNS entries allocated to the API implementation

A European company has customers all across Europe, and the IT department is migrating from an older platform to MuleSoft. The main requirements are that the new platform should allow redeployments with zero downtime and deployment of applications to multiple runtime versions, provide security and speed, and utilize Anypoint MQ as the message service. Which runtime plane should the company select based on the requirements without additional network configuration?

A. Runtime Fabric on VMs / Bare Metal for the runtime plane

B. Customer-hosted runtime plane

C. MuleSoft-hosted runtime plane (CloudHub)

D. Anypoint Runtime Fabric on Self-Managed Kubernetes for the runtime plane

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

What do the API invocation metrics provided by Anypoint Platform provide?

A.

ROI metrics from APIs that can be directly shared with business users

B.

Measurements of the effectiveness of the application network based on the level of reuse

C.

Data on past API invocations to help identify anomalies and usage patterns across various APIs

D.

Proactive identification of likely future policy violations that exceed a given threat
threshold
