Question 1

A developer deploys an API to CloudHub and applies an OAuth policy on API Manager. During testing, the

API response is slow, so the developer reconfigures the API so that the out-of-the-box HTTP Caching policy

is applied first, and the OAuth API policy is applied second.

What will happen when an HTTP request is received?

Options :

A :

In case of a cache hit, both the OAuth and HTTP Caching policies are evaluated; then the cached

response is returned to the caller

B :

In case of a cache it, only the HTTP Caching policy is evaluating; then the cached response is returned

to the caller

C :

In case of a cache miss, only the HTTP Caching policy is evaluated; then the API retrieves the data from

the API implementation, and the policy stores the data to be cached in Object Store

D :

In case of a cache miss, both the OAuth and HTTP Caching policies are evaluated; then the API

retrieves the data from the API implementation, and the policy does not store the data in Object Store

Answer: B

Question 2

An organization uses CloudHub to deploy all of its applications.

How can a common-global-handler flow be configured so that it can be reused across all of the organization’s

deployed applications?

Options :

A :

Create a Mule plugin project

Create a common-global-error-handler flow inside the plugin project.

Use this plugin as a dependency in all Mute applications.

Import that configuration file in Mute applications.

B :

Create a common-global-error-handler flow in all Mule Applications Refer to it flow-ref wherever

needed.

C :

Create a Mule Plugin project

Create a common-global-error-handler flow inside the plugin project.

Use this plugin as a dependency in all Mule applications

D :

Create a Mule daman project.

Create a common-global-error-handler flow inside the domain project.

Use this domain project as a dependency.

Answer: C

Question 3

A mule application exposes and API for creating payments. An Operations team wants to ensure that the Payment API is up and running at all times in production. Which approach should be used to test that the payment API is working in production?

Options :

A : Create a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API

B : Configure the application to send health data to an external system

C : Create a health check endpoint that reuses the same port number and HTTP Listener configuration as the API itself

D : Monitor the Payment API directly sending real customer payment data

Answer: A

Question 4

A Mule API receives a JSON payload and updates the target system with the payload. The developer uses

JSON schemas to ensure the data is valid.

How can the data be validation before posting to the target system?

Options :

A :

Use a DataWeave 2.09 transform operation, and at the log of the DataWeave script, add:

%dw 2.0

Import.json-moduls

B :

Using the DataWeave if Else condition test the values of the payload against the examples included in

the schema

C :

Apply the JSON Schema policy in API Manager and reference the correct schema in the policy

configuration

D :

Add the JSON module dependency and add the validate-schema operation in the flow, configured to

reference the schema

Answer: D

Question 5

Which properties are mandatory on the HTTP Connector configuration in order to use the OAuth 2.0 Authorization Code grant type for authentication?

Options :

A : External callback URL, access token URL, client ID response access token

B : Token URL, authorization URL, client ID, client secret local callback URL

C : External callback URL, access token URL, client ID, response refresh token
