A web client sends a request to http;//localhost:8081?dept=sales. What is the correct DataWeave expression to access the value of dept?

• attributes.queryParams.dept
• attributes.dept
• message.queryParams.dept
• vars.dept

According to MuleSoft. what is the first step to create a Modern API?

• Gather a list of requirements to secure the API
• Create an API specification and get feedback from stakeholders
• Performance tune and optimize the backend systems and network
• Create a prototype of the API implementation

A Mule application contains two HTTP Listeners, each configured for different API endpoints: http://acme.com/apis/orders and http: //acme .com/a pis/customers. What base path value should be set in an HTT? Listener config element so that it can be used to configure both HTTP Listeners?

• /apis/?
• /apis/
• /apis/orders|customers
• /apis/*

An On Table Row Database listener retrieves data from a table that contains record_id, an increasing numerical column. How should the listener be configured so it retrieves new rows at most one time?

• Set the target to store the last retrieved record_id value
• Set the ObjectStore to store the last retrieved record_id value
• Set the target to the record_id column
• Set the watermark column to the record id column

Why would a Mule application use the ${http.port} property placeholder for its HTTP Listener port when it is deployed to CloudHub?

• Allows CloudHub to automatically change the HTTP port to allow external clients to connect to the HTTP Listener
• Allows CloudHub to automatically register the application with API Manager
• Allows MuleSoft Support to troubleshoot the application by connecting directly to the HTTP Listener
• Allows clients to VPN directly to the application at the Mule application's configured HTTP port

An SLA based policy has been enabled in API Manager. What is the next step to configure the API proxy to enforce the new SLA policy?

• Add new property placeholders and redeploy the API proxy
• Add new environment variables and restart the API proxy
• Restart the API proxy to clear the API policy cache
• Add required headers to the RAML specification and redeploy the new API proxy

A Database On Table Row listener retrieves data from a CUSTOMER table that contains a primary key userjd column and an increasing kxjin_date_time column. Neither column allows duplicate values. How should the listener be configured so it retrieves each row at most one time?

• Set the watermark column to the bgin_date_time column
• Set the target value to the last retrieved login_date_time value
• Set the target value to the last retrieved user_jd value
• Set the watermark column to the user_Id column

A RAML specification is defined to manage customers with a unique identifier for each customer record. What URI does MuleSoft recommend to uniquely access the customer identified with the unique ID 1234?

• /customers?custid=true&custid=1234
• /customers/1234
• /customers/custid=1234
• /customers?operation=get&custid=1234

An API implementation has been deployed to CloudHub and now needs to be governed. IT will not allocate additional vCore for a new Mule application to act as an API proxy. What is the next step to preseive the current vCore usage, but still allow the Mule application to be managed by API Manager?

• Register the same API implementation in Runtime Manager to connect to API Manager
• Modify the API implementation to use auto-discovery to register with API Manager
• Upload the Mule application's JAR file to the API instance in API Manager
• Deploy the same API implementation behind a VPC and configure the VPC to connect to API Manager

By default, what happens to a file after it is read using an FTP connector Read operation?

• The file is deleted from the folder
• The file is moved to a different folder
• The file stays in the same folder unchanged
• The file is renamed in the same folder
