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

When implementing a synchronous API where the event source is an HTTP Listener, a developer needs to

return the same correlation ID back to the caller in the HTTP response header.

How can this be achieved?

Options :

A : Enable the auto-generate CorrelationID option when scaffolding the flow

B : Enable the CorrelationID checkbox in the HTTP Listener configuration

C : Configure a custom correlation policy

D : NO action is needed as the correlation ID is returned to the caller in the response header by default

Answer: D

Question 3

Refer to the exhibit.

What action must be performed to log all the errors raised by the VM Connector?

Options :

A :

Add < AsyncLOgger name=’orgroute.extensions vm’ level=ERROR’I > inside the Logger tag

B :

Add < AsyncLOgger name=’orgroute.extensions vm’ level=ERROR’/ > inside the Appenders tag

C :

Configure < Logger level-‘ERROR’/ > inside the VM Connector configuration

D :

Nothing, as error-level events are automatically logged

Answer: B

Question 4

Refer to the exhibit.

A developer generates the base scaffolding for an API in Anypoint Studio.

Which HTTP status code is returned while testing using the API Kit console if no values are entered in

client-secret?

Options :

A : HTTP status code:200

B : HTTP status code:403

C : HTTP status code:400

D : HTTP status code:500

Answer: B

Question 5

A Mule application deployed to a standardalone Mule runtime uses VM queues to publish messages to be

consumed asynchronously by another flow.

In the case of a system failure, what will happen to in-flight messages in the VM queues that have been

consumed?

Options :

A : For nay type of queue, the message will be processed after the system comes online

B : For persistent queues, the message will be processed after the system comes online

C : For transient queues, the message will be processed after the system comes online

D : For any type of queue, the message will be lost
