MCPA-Level-1 Exam Training Practice Tests (MuleSoft Certified Platform Architect

Question 1

A customer wants to host their MuleSoft applications in CloudHub 1.0, and these applications should be available at the domain https://api.acmecorp.com.
After creating a dedicated load balancer (DLB) called acme-dib-prod, which further action must the customer take to complete the configuration?

A. Configure the DLB with a TLS certificate for api.acmecorp.com and create an A record for api.
acmecorp.com to the public IP addresses associated with their DLB B. Configure the DLB with a TLS certificate for aplacmecorp.com and create a CNAME record from api.aomecorp.com to acme-dib-prod.ei.cloubhub.io C. Configure the DLB with a TLS certificate for api.acmecorp.com and create a CNAME record from api.
acmecorp.com to acme-dib-prod.|lb.anypointdns.net D. Configure the DLB with a TLS certificate for acme-dib-prod.Jb.anypointdns.net and create a CNAME record from api.acmecorp:com to acme-dlb-prod.lb.anypointdns.net

Question 2

An enterprise is embarking on the API-led digital transformation journey, and the central IT team has started to define System APIs. Currently there is no Enterprise Data Model being defined within the enterprise, and the definition of a clean Bounded Context Data Model requires too much effort.
According to MuleSoft's recommended guidelines, how should the System API data model be defined?

A. The data model should define its own naming convention, and not follow the same naming as the back- end systems B. If there are misspellings of the data fields in the back-end system, Systerm APIs should not correct it, and expose it as-is to mirror the back-end systems C. The System APIs should expose all back-end system fields D. The data model of the System APIs should make use of data types that approximately mirror those from the back-end systems

Question 3

A Mule application exposes an HTTPS endpoint and is deployed to the CloudHub Shared Worker Cloud. All traffic to that Mule application must stay inside the AWS VPC.
To what TCP port do API invocations to that Mule application need to be sent?

A. 443 B. 8091 C. 8082 D. 8081

Question 4

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) 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, B. 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 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.

Question 5

A team is planning to enhance an Experience API specification, and they are following API-led connectivity design principles.
What is their motivation for enhancing the API?

A. The primary API consumer wants certain kinds of endpoints changed from the Center for Enablement standard to the consumer system standard B. A Canonical Data Model is being adopted that impacts several types of data included in the API C. The underlying System API is updated to provide more detailed data for several heavily used resources D. An IP Allowlist policy is being added to the API instances in the Development and Staging environments

Question 6

A company deploys Mule applications with default configurations through Runtime Manager to customer- hosted Mule runtimes. Each Mule application is an API implementation that exposes RESTful interfaces to API clients. The Mule runtimes are managed by the MuleSoft-hosted control plane. The payload is never used by any Logger components.
When an API client sends an HTTP request to a customer-hosted Mule application, which metadata or data (payload) is pushed to the MuleSoft-hosted control plane?

A. Only the metadata B. No data C. Only the data D. The data and metadata

Question 7

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 irrespective of the deployment model D. From the Mule runtime or the API Manager, depending on the type of data

Question 8

In which layer of API-led connectivity, does the business logic orchestration reside?

A. Experience Layer B. Process Layer C. System Layer

Question 9

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 total process execution time is now 100 milliseconds (.1 seconds) B. The application scalability threshold is five requests per second regardless of the horizontal scaling C. Horizontal scaling cannot be applied to an already-running application D. The application scalability threshold is now 10 requests per second

Question 10

An Order API must be designed that contains significant amounts of integration logic and involves the invocation of the Product API.
The power relationship between Order API and Product API is one of "Customer/Supplier", because the Product API is used heavily throughout the organization and is developed by a dedicated development team located in the office of the CTO.
What strategy should be used to deal with the API data model of the Product API within the Order API?

A. Implement an anti-corruption layer in the Order API that transforms the Product API data model into internal data types of the Order API B. Convince the development team of the Product API to adopt the API data model of the Order API such that the integration logic of the Order API can work with one consistent internal data model C. Work with the API data types of the Product API directly when implementing the integration logic of the Order API such that the Order API uses the same (unchanged) data types as the Product API D. Start an organization-wide data modeling initiative that will result in an Enterprise Data Model that will then be used in both the Product API and the Order API

Question 11

Refer to the exhibit. An organization needs to enable access to their customer data from both a mobile app and a web application, which each need access to common fields as well as certain unique fields.
The data is available partially in a database and partially in a 3rd-party CRM system.
What APIs should be created to best fit these design requirements?

A) A Process API that contains the data required by both the web and mobile apps, allowing these applications to invoke it directly and access the data they need thereby providing the flexibility to add more fields in the future without needing API changes B) One set of APIs (Experience API, Process API, and System API) for the web app, and another set for the mobile app C) Separate Experience APIs for the mobile and web app, but a common Process API that invokes separate System APIs created for the database and CRM system

D) A common Experience API used by both the web and mobile apps, but separate Process APIs for the web and mobile apps that interact with the database and the CRM System

A. Option D B. Option B C. Option A D. Option C
