MuleSoft Certified Developer - Level 2 (Mule 4) Sample Questions:
1. A system API that communicates to an underlying MySQL database is deploying to CloudHub. The DevOps team requires a readiness endpoint to monitor all system APIs.
Which strategy should be used to implement this endpoint?
A) Create a dedicated endpoint that responds with the API status only
B) Create a dedicated endpoint that responds with the API status and reachability of the underlying systems
C) Use an existing resource endpoint of the API
D) Create a dedicated endpoint that responds with the API status and health of the server
2. 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?
A) HTTP status code:500
B) HTTP status code:200
C) HTTP status code:400
D) HTTP status code:403
3. 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?
A) Use flow variables within every logger processor to log the order ID
B) Use the Tracing module to set logging variables with a Mapped Diagnostic Context
C) Set a flow variable and edit the log4/2.xml file to output the variable as part of the message pattern
D) Create a custom XML SDK component to wrap the logger processor and automatically add the order ID within the connector
4. 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?
A) 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
B) In case of a cache hit, both the OAuth and HTTP Caching policies are evaluated; 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 it, only the HTTP Caching policy is evaluating; then the cached response is returned to the caller
5. Refer to the exhibit.
When creating a new project, which API implementation allows for selecting the correct API version and scaffolding the flows from the API specification?
A) Generate a local RAML from anypoint Studio
B) Import RAML from local file
C) Download RAML from Design Center
D) Import a published API
