Question No. 1

A Mule application contain two policies Policy A and Policy A has order1, and Policy B has order 2. Policy A Policy B, and a flow are defined by he configuration below.

When a HTTP request arrives at the Mule application's endpoint, what will be the execution order?

Show Answer Hide Answer
Correct Answer: A

Based on the configuration below, when a HTTP request arrives at the Mule application's endpoint, the execution order will be A1, B1, F1, B2, A2. This is because policies are executed before and after the API implementation flow according to their order attribute. Policy A has order 1, which means it is executed first before Policy B, which has order 2. The flow is executed after both policies are executed before the flow. Then, Policy B is executed after the flow before Policy A is executed after the flow. Reference: https://docs.mulesoft.com/api-manager/2.x/policies-policy-order


Question No. 2

A Mule application for processing orders must log the order ID for every log message output.

What is a best practice to enrich every log message with the order ID?

Show Answer Hide Answer
Correct Answer: D

To enrich every log message with the order ID, the developer should use the Tracing module to set logging variables with a Mapped Diagnostic Context (MDC). The Tracing module allows adding custom key-value pairs to log messages using MDC variables. The developer can use Set Logging Variables operation to set the order ID as an MDC variable and then use it in any logger processor within the same thread or event.

Question No. 3

Refer to the exhibit.

What is the result if ''Insecure'' selected as part of the HTTP Listener configuration?

Show Answer Hide Answer
Correct Answer: C

Based on the exhibit below, if 'Insecure' is selected as part of the HTTP Listener configuration, the HTTP listener will only accept HTTP requests. This means that no TLS context will be configured for this listener and no encryption or authentication will be applied to incoming requests. The protocol attribute of this listener will be set to HTTP instead of HTTPS. Reference: https://docs.mulesoft.com/http-connector/1.6/http-listener-ref#insecure


Question No. 4

An API has been developed and deployed to CloudHub Among the policies applied to this API is an allowlist of IP addresses. A developer wants to run a test in Anypoint Studio and does not want any policies applied because their workstation is not included in the allowlist.

What must the developer do in order to run this test locally without the policies applied?

Show Answer Hide Answer
Correct Answer: A

To run a test locally without the policies applied, the developer should create a properties file specifically for local development and set the API instance ID to a value that is not used in API Manager. This way, the developer can use different configuration properties for different environments and avoid triggering API autodiscovery when running tests locally. API autodiscovery is a mechanism that associates an API implementation with its corresponding API specification and policies in API Manager based on its API instance ID. By setting this ID to a value that does not exist in API Manager, the developer can prevent API autodiscovery from finding and applying any policies to the local test. Reference: https://docs.mulesoft.com/api-manager/2.x/api-auto-discovery-new-concept#configuring-api-autodiscovery https://docs.mulesoft.com/mule-runtime/4.3/configuring-properties


Question No. 5

A developer has created the first version of an API designed for business partners to work commodity prices.

What should developer do to allow more than one major version of the same API to be exposed by the implementation?

Show Answer Hide Answer
Correct Answer: C

To allow more than one major version of the same API to be exposed by the implementation, the developer should modify the baseUri property in the RAML file to include a variable that indicates the version number. The baseUri property defines the base URL of the API and can include variables that are replaced with actual values when mocking or deploying the API. By using a variable for the version number, the developer can expose different versions of the API using different base URLs and avoid conflicts or confusion.
