Anypoint Exchange

Question 16

What is the main purpose of Flow designer in Design Center?

Answer 16

To design and develop fully functional Mule applications in a hosted development environment.

Question 17

A web client submits a GET request to a Mule 4 application to the endpoint /customers?id=48493.

Where is the id stored in the Mule event by the HTTP Listener?

Answer 17

Attributes

Question 18

What asset can NOT be created using Design Center?

Answer 18

API Portals

Question 19

What is Spec Driven development?

Answer 19

A development process where the application is built in two distinct phases

1. The creation of a spec (the design phase)
2. Development of code to match the spec (the development phase)

Question 20

The API console is available in:

Answer 20

API Designer so the API designer can test

API portals in Exchange so users/developers can test

Question 21

There are many RAML fragment types:

Answer 21

Data types, examples, traits, resource types, overlays, extensions, security schemes, documentation, annotations, and libraries

Question 22

You publish RAML API specifications and RAML fragments to the exchange from API Designer

Answer 22

API portals are automatically created for REST APIs added to Exchange

• An API console for consuming and testing APIs
• An automatically generated API endpoint that uses a mocking service to allow the API to be tested without having to implement it
• API portals can be shared with internal and external users

Question 23

What is not part of a mule event?

Answer 23

inboundProperties

Question 24

How does APIkit determine the number of flows to generate from a RAML specification?

Answer 24

Creates a separate flow for each HTTP method

Question 25

Answer 25

Java

Question 26

What is the minimum required configuration in a flow for a Mule application to compile?

Answer 26

An event processor

Question 27

What is the purpose of the api:router element in APIkit?

Answer 27

Validates requests against RAML API specifications and routes them to the API implementations

Question 28

Restricting Access to APIs

Answer 28

* An API proxy is an application that controls access to a web service, restricting access and usage through the use of an API gateway * The API Gateway is a runtime designed and optimized to host an API or to open a connection to an API deployed to another runtime

Question 29

The API Gateway is the point of control

Answer 29

* **Determines which traffic** is authorized to pass through the API to backend service * **Meters the traffic** flowing through * **Logs** all transactions, collecting and tracking analytics data * Applies runtime policies to **enforce governance** like rate limiting, throttling, and caching.

Question 30

Using API Manger to manage access to APIs

Answer 30

* **Create** proxy applications * **Deploy** proxies to an API Gateway runtime * Specify throttling, security, and other **policies** * Specify **tiers** with different types of access to APIs * Approve, reject, or revoke **access** to APIs by clients * **Promote** managed APIs between environments * Review **analytics**

Question 31

API Autodiscovery

Answer 31

Mechanism that enables a deployed Mule application to download policies from API Manager, act as its own proxy.

Question 32

SLA -Service Level Agreement

Answer 32

Defines the # of requests that can be made per time frame to an API

Question 33

To enforce and apply SLA based rate limiting policy, SLA based policies require all applications that consume the API to:

Answer 33

* Register for access to a specific tier * Pass their client credentials in calls made to the API

Question 34

What is the purpose of API autodiscovery?

Answer 34

Allows a deployed Mule application to connect with API Manager to download policies and act as its own API proxy

Question 35

What does the Mule runtime use to enforce policies and limit access to APIs?

Answer 35

The Mule runtime's embedded API Gateway

Question 36

How many Mule applications can run on a CloudHub worker?

Answer 36

At most one
