Refer to the exhibit. An organization is running a Mule standalone runtime and has configured Active Directory as the Anypoint Platform external Identity Provider. The organization does not have budget for other system components. What policy should be applied to all instances of APIs in the organization to most effecuvelyKestrict access to a specific group of internal users?

• AA. Apply a basic authentication - LDAP policy; the internal Active Directory will be configured as the LDAP source for authenticating users
• BB. Apply a client ID enforcement policy; the specific group of users will configure their client applications to use their specific client credentials
• CC. Apply an IP whitelist policy; only the specific users' workstations will be in the whitelist
• DD. Apply an OAuth 2.0 access token enforcement policy; the internal Active Directory will be configured as the OAuth server

What best describes the Fully Qualified Domain Names (FQDNs), also known as DNS entries, created when a Mule application is deployed to the CloudHub Shared Worker Cloud?

• AA. A fixed number of FQDNs are created, IRRESPECTIVE of the environment and VPC design
• BB. The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region
• CC. The FQDNs are determined by the application name, but can be modified by an administrator after deployment
• DD. The FQDNs are determined by both the application name and the Anypoint Platform organization

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?

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

A company has created a successful enterprise data model (EDM). The company is committed to building an application network by adopting modern APIs as a core enabler of the company's IT operating model. At what API tiers (experience, process, system) should the company require reusing the EDM when designing modern API data models?

• AA. At the experience and process tiers
• BB. At the experience and system tiers
• CC. At the process and system tiers
• DD. At the experience, process, and system tiers

An organization uses various cloud-based SaaS systems and multiple on-premises systems. The on-premises systems are an important part of the organization's application network and can only be accessed from within the organization's intranet. What is the best way to configure and use Anypoint Platform to support integrations with both the cloud-based SaaS systems and on-premises systems?

• AA. Use CloudHub-deployed Mule runtimes in an Anypoint VPC managed by Anypoint Platform Private Cloud Edition control plane
• BB. Use CloudHub-deployed Mule runtimes in the shared worker cloud managed by the MuleSoft-hosted Anypoint Platform control plane
• CC. Use an on-premises installation of Mule runtimes that are completely isolated with NO external network access, managed by the Anypoint Platform Private Cloud Edition control plane
• DD. Use a combination of Cloud Hub-deployed and manually provisioned on-premises Mule runtimes managed by the MuleSoft-hosted Anypoint Platform control plane
• EE. Option A
• FF. Option B
• GG. Option C
• HH. Option D

Which of the following best fits the definition of API-led connectivity?

• AA. API-led connectivity is not just an architecture or technology but also a way to organize people and processes for efficient IT delivery in the organization
• BB. API-led connectivity is a 3-layered architecture covering Experience, Process and System layers
• CC. API-led connectivity is a technology which enabled us to implement Experience, Process and System layer based APIs

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

• AA. Implement a system API named customerManagement which has all the functionalities wrapped in it asvarious operations/resources
• BB. Implement different system APIs named createCustomer, amendCustomer, retrieveCustomer and suspendCustomer as they are modular and has seperation of concerns
• CC. Implement different system APIs named createCustomerInCRMZ, amendCustomerInCRMZ, retrieveCustomerFromCRMZ and suspendCustomerInCRMZ as they are modular and has seperation of concerns

Refer to the exhibit. Three business processes need to be implemented, and the implementations need to communicate with several different SaaS applications. These processes are owned by separate (siloed) LOBs and are mainly independent of each other, but do share a few business entities. Each LOB has one development team and their own budget In this organizational context, what is the most effective approach to choose the API data models for the APIs that will implement these business processes with minimal redundancy of the data models?

• AA. Build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities
• BB. Build distinct data models for each API to follow established micro-services and Agile API-centric practices
• CC. Build all API data models using XML schema to drive consistency and reuse across the organization
• DD. Build one centralized Canonical Data Model (Enterprise Data Model) that unifies all the data types from all three business processes, ensuring the data model is consistent and non-redundant
• EE. Option A
• FF. Option B
• GG. Option C
• HH. Option D

Correct answer: A

Explanation

Correct Answer Build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities. ***************************************** >> The options w.r.t building API data models using XML schema/ Agile API-centric practices are irrelevant to the scenario given in the question. So these two are INVALID. >> Building EDM (Enterprise Data Model) is not feasible or right fit for this scenario as the teams and LOBs work in silo and they all have different initiatives, budget etc.. Building EDM needs intensive coordination among all the team which evidently seems not possible in this scenario. So, the right fit for this scenario is to build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities.

A code-centric API documentation environment should allow API consumers to investigate and execute API client source code that demonstrates invoking one or more APIs as part of representative scenarios. What is the most effective way to provide this type of code-centric API documentation environment using Anypoint Platform?

• AA. Enable mocking services for each of the relevant APIs and expose them via their Anypoint Exchange entry
• BB. Ensure the APIs are well documented through their Anypoint Exchange entries and API Consoles and share these pages with all API consumers
• CC. Create API Notebooks and include them in the relevant Anypoint Exchange entries
• DD. Make relevant APIs discoverable via an Anypoint Exchange entry

A company uses a hybrid Anypoint Platform deployment model that combines the EU control plane with customer-hosted Mule runtimes. After successfully testing a Mule API implementation in the Staging environment, the Mule API implementation is set with environment-specific properties and must be promoted to the Production environment. What is a way that MuleSoft recommends to configure the Mule API implementation and automate its promotion to the Production environment?

• AA. Bundle properties files for each environment into the Mule API implementation's deployable archive, then promote the Mule API implementation to the Production environment using Anypoint CLI or the Anypoint Platform REST APIs
• BB. Modify the Mule API implementation's properties in the API Manager Properties tab, then promote the Mule API implementation to the Production environment using API Manager
• CC. Modify the Mule API implementation's properties in Anypoint Exchange, then promote the Mule API implementation to the Production environment using Runtime Manager
• DD. Use an API policy to change properties in the Mule API implementation deployed to the Staging environment and another API policy to deploy the Mule API implementation to the Production environment
