Question # 4

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?

A.

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 APIsB.

B.

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

C.

Modify the Mule API implementation's properties in Anypoint Exchange, then promote the Mule API implementation to the Production environment using Runtime Manager

D.

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

Question # 5

What is true about automating interactions with Anypoint Platform using tools such as Anypoint Platform REST APIs, Anypoint CU, or the Mule Maven plugin?

A.

Access to Anypoint Platform APIs and Anypoint CU can be controlled separately through the roles and permissions in Anypoint Platform, so that specific users can get access to Anypoint CLI white others get access to the platform APIs

B.

Anypoint Platform APIs can ONLY automate interactions with CloudHub, while the Mule Maven plugin is required for deployment to customer-hosted Mule runtimes

C.

By default, the Anypoint CLI and Mule Maven plugin are NOT included in the Mule runtime, so are NOT available to be used by deployed Mule applications

D.

API policies can be applied to the Anypoint Platform APIs so that ONLY certain LOBs have access to specific functions

Question # 6

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

Question # 7

A system API is deployed to a primary environment as well as to a disaster recovery (DR) environment, with different DNS names in each environment. A process API is a client to the system API and is being rate limited by the system API, with different limits in each of the environments. The system API's DR environment provides only 20% of the rate limiting offered by the primary environment. What is the best API fault-tolerant invocation strategy to reduce overall errors in the process API, given these conditions and constraints?

A.

Invoke the system API deployed to the primary environment; add timeout and retry logic to the process API to avoid intermittent failures; if it still fails, invoke the system API deployed to the DR environment

B.

Invoke the system API deployed to the primary environment; add retry logic to the process API to handle intermittent failures by invoking the system API deployed to the DR environment

C.

In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment; add timeout and retry logic to the process API to avoid intermittent failures; add logic to the process API to combine the results

D.

Invoke the system API deployed to the primary environment; add timeout and retry logic to the process API to avoid intermittent failures; if it still fails, invoke a copy of the process API deployed to the DR environment

Question # 8

What is a best practice when building System APIs?

A.

Document the API using an easily consumable asset like a RAML definition

B.

Model all API resources and methods to closely mimic the operations of the backend system

C.

Build an Enterprise Data Model (Canonical Data Model) for each backend system and apply it to System APIs

D.

Expose to API clients all technical details of the API implementation's interaction wifch the backend system

Question # 9

Which of the below, when used together, makes the IT Operational Model effective?

A.

Create reusable assets, Do marketing on the created assets across organization, Arrange time to time LOB reviews to ensure assets are being consumed or not

B.

Create reusable assets, Make them discoverable so that LOB teams can self-serve and browse the APIs, Get active feedback and usage metrics

C.

Create resuable assets, make them discoverable so that LOB teams can self-serve and browse the APIs

2. LOB IT owns and focuses on Process Layer APIs

3. App Developers owns and focuses on System Layer APIs

C.

1. App Developers owns and focuses on Experience Layer APIs

2. LOB IT owns and focuses on Process Layer APIs

3. Central IT owns and focuses on System Layer APIs

Question # 11

What is a key requirement when using an external Identity Provider for Client Management in Anypoint Platform?

A.

Single sign-on is required to sign in to Anypoint Platform

B.

The application network must include System APIs that interact with the Identity Provider

C.

To invoke OAuth 2.0-protected APIs managed by Anypoint Platform, API clients must submit access tokens issued by that same Identity Provider

D.

APIs managed by Anypoint Platform must be protected by SAML 2.0 policies

Question # 12

What is a typical result of using a fine-grained rather than a coarse-grained API deployment model to implement a given business process?

A.

A decrease in the number of connections within the application network supporting the business process

B.

A higher number of discoverable API-related assets in the application network

C.

A better response time for the end user as a result of the APIs being smaller in scope and complexity

D.

An overall tower usage of resources because each fine-grained API consumes less resources

Question # 13

What should be ensured before sharing an API through a public Anypoint Exchange portal?

A.

The visibility level of the API instances of that API that need to be publicly accessible should be set to public visibility

B.

The users needing access to the API should be added to the appropriate role in Anypoint Platform

C.

The API should be functional with at least an initial implementation deployed and accessible for users to interact with

D.

The API should be secured using one of the supported authentication/authorization mechanisms to ensure that data is not compromised

Question # 14

A company has started to create an application network and is now planning to implement a Center for Enablement (C4E) organizational model. What key factor would lead the company to decide upon a federated rather than a centralized C4E?

A.

When there are a large number of existing common assets shared by development teams

B.

When various teams responsible for creating APIs are new to integration and hence need extensive training

C.

When development is already organized into several independent initiatives or groups

D.

When the majority of the applications in the application network are cloud based
