What is the difference between a subflow and a sync flow?

A. No difference

B. Subflow has no error handling of its own and sync flow does

C. Sync flow has no error handling of its own and subflow does

D. Subflow is synchronous and sync flow is asynchronous

B. Subflow has no error handling of its own and sync flow does

Explanation:
Correct answer is Subflow has no error handling implementation where as sync flow has Subflow:
A subflow processes messages synchronously (relative to the flow that triggered its execution) and always inherits both the processing strategy and exception strategy employed by the triggering flow. While a subflow is running, processing on the triggering flow pauses, then resumes only after the subflow completes its processing and hands the message back to the triggering flow.
Synchronous Flow:
A synchronous flow, like a subflow, processes messages synchronously (relative to the flow that triggered its execution). While a synchronous flow is running, processing on the triggering flow pauses, then resumes only after the synchronous flow completes its processing and hands the message back to the triggering flow. However, unlike a subflow, this type of flow does not inherit processing or exception strategies from the triggering flow.
This type of flow processes messages along a single thread, which is ideally suited to transactional processing.

Where would you create SLA Tiers for an API?

A. Exchange

B. API Manager

C. Anypoint Studio

D. In RAML specifications

B. API Manager

Explanation:
MuleSoft Doc Ref : https://docs.mulesoft.com/api-manager/2.x/policy-mule3-tutorialmanage- an-api#to-add-the-tier
Steps to create SLA Tier are as follows:
1) In API Manager, in API Administration, click a version.
2) Check that the API supports resource-level policies: On the API version details page, in Status, click Configure Endpoint, and check that Type is RAML.
3) Choose the SLA Tiers, and click Add SLA Tier. Set up limit on SLA tier.

Refer to the exhibits.

The two Mule configuration files belong to the same Mule project. Each HTTP Listener is configured with the same host string and the port number, path, and operation values are shown in the display names.
What is the minimum number of global elements that must be defined to support all these HTTP Listeners?

A. 1

B. 2

C. 3

D. 4

C. 3

Explanation:
In this case three configurations will be required each for port 8000, 6000 and 7000.
There would be three global elements defined for HTTP connections.
Each HTTP connection will have host and port. One example shown below with host as localhost and port 6000.

As a part of requirement , application property defined below needs to be accessed as dataweave expression. What is the correct expression to map it to port value?

A. { port : p('db.port')}

B. { port : {db:port}}

C. { port : p['db.port']}

D. Application property cannot be accessed in Dataweave

A. { port : p('db.port')}

Option 1 is the correct syntax

What of the below is not a feature of API Notebooks?

A. API documentation

B. Creates a client for an API

C. Creates a mock service for an API

D. Perform authenticated live calls on a real server

C. Creates a mock service for an API

Explanation:
Correct answer is Creates a mock service for an API
API Notebook is an open source, shareable web application for API documentation, interactive API tutorial and example generatation, and a client for your API endpoints. Using API Notebook, you can make requests and quickly transform the responses into readable format. However it cannot be used to mock service for an API.

D.

Add the specification to a Mule project's src/main/resources/api folder
