Where would you create SLA Tiers for an API?
A. Exchange
B. API Manager
C. Anypoint Studio
D. In RAML specifications
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 exhibit. The main flow contains an HTTP Request in the middle of the flow.
The HTTP Listeners and HTTP request use default configurations.
What values are accessible to the Logger at the end of the flow after a web client submit
request to http://local:801/order?color=red?
A. payload
B. payload quantity var
C. payload color query param
D. payload quantity var color query param
Correct answer is as below. Query parameters are replaced when external HTTP call is
invoked.
payload
producer var
What is the default port used by Mule application debugger configuration in Anypoint Studio?
A. 8082
B. 8080
C. 7777
D. 6666
Explanation: By default, Debugger listens for incoming TCP connections on localhost port 6666 You can change this in a project's run configuration.
What is the correct way to format the decimal 200.1234 as a string to two decimal places?
A. 200.1234 as string as format: ".0#"
B. 200.1234 as String {format: ".0#"}
C. 200.1234 as String as format: ".0#"
D. 200.1234 as string {format: ".0#"}
Correct answer is 200.1234 as String {format: ".0#"} . Rest all options are not syntactically correct.
What MuleSoft API-led connectivity layer is intended to expose part of a backend database without business logic?
A. Data layer
B. Process layer
C. Experience layer
D. System layer
Explanation:
Correct answer is System layer
System APIs provide a means for insulating the data consumers from the complexity or
changes to the underlying backend systems.
MuleSoft recommends three-layered approach to API-led connectivity, highlighting the
three layers:
* System APIs
* Process APIs
* Experience APIs
System APIs are the core systems of record underlying core systems of record (e.g. ERPs,
key customer and billing systems, databases, etc.). Process APIs allow you to define a
common process which the organization can share, and these APIs perform specific
functions, provide access to non-central data, and may be built by either Central IT or Line
of Business IT. And finally, the Experience APIs are the means by which data can be
reconfigured so that it is most easily consumed by its intended audience, all from a
common data source.
The three-layered structure allows for a seamless flow of data from systems of record to
new experiences, and allows for reusability of assets rather than point to point connections.
This approach provides a distributed and tailored approach to architecture, greater
flexibility through loose coupling, and deeper operational visibility into what is being built.
Which one of them is NOT a flow in Mule?
A. sync flow
B. subflow
C. async sub flow
