Question 52
An organization has decided on a cloudhub migration strategy that aims to minimize the organizations own IT resources. Currently, the organizational has all of its Mule applications running on its own premises and uses an premises load balancer that exposes all APIs under the base URL https://api.acme.com As part of the migration strategy, the organization plans to migrate all of its Mule applications and load balancer to cloudhub What is the most straight-forward and cost effective approach to the Mule applications deployment and load balancing that preserves the public URLs?
An API client is implemented as a Mule application that includes an HTTP Request operation using a default configuration. The HTTP Request operation invokes an external API that follows standard HTTP status code conventions, which causes the HTTP Request operation to return a 4xx status code. What is a possible cause of this status code response?
Correct Answer: D
Correct choice is: "The external API reported an error with the HTTP request that was received from the outbound HTTP Request operation of the Mule application" Understanding HTTP 4XX Client Error Response Codes : A 4XX Error is an error that arises in cases where there is a problem with the user's request, and not with the server. Such cases usually arise when a user's access to a webpage is restricted, the user misspells the URL, or when a webpage is nonexistent or removed from the public's view. In short, it is an error that occurs because of a mismatch between what a user is trying to access, and its availability to the user - either because the user does not have the right to access it, or because what the user is trying to access simply does not exist. Some of the examples of 4XX errors are 400 Bad Request The server could not understand the request due to invalid syntax. 401 Unauthorized Although the HTTP standard specifies "unauthorized", semantically this response means "unauthenticated". That is, the client must authenticate itself to get the requested response. 403 Forbidden The client does not have access rights to the content; that is, it is unauthorized, so the server is refusing to give the requested resource. Unlike 401, the client's identity is known to the server. 404 Not Found The server can not find the requested resource. In the browser, this means the URL is not recognized. In an API, this can also mean that the endpoint is valid but the resource itself does not exist. Servers may also send this response instead of 403 to hide the existence of a resource from an unauthorized client. This response code is probably the most famous one due to its frequent occurrence on the web. 405 Method Not Allowed The request method is known by the server but has been disabled and cannot be used. For example, an API may forbid DELETE-ing a resource. The two mandatory methods, GET and HEAD, must never be disabled and should not return this error code. 406 Not Acceptable This response is sent when the web server, after performing server-driven content negotiation, doesn't find any content that conforms to the criteria given by the user agent. The external API reported that the API implementation has moved to a different external endpoint cannot be the correct answer as in this situation 301 Moved Permanently The URL of the requested resource has been changed permanently. The new URL is given in the response. ---------------------------------------------------------------------------------------------------------------------------------------- In Lay man's term the scenario would be: API CLIENT -> MuleSoft API - HTTP request "Hey, API.. process this" -> External API API CLIENT <- MuleSoft API - http response "I'm sorry Client.. something is wrong with that request" <- (4XX) External API
Question 54
Which Salesforce API is invoked to deploy, retrieve, create or delete customization information such as custom object definitions using a Mule Salesforce connector in a Mule application?
Correct Answer: A
* urpose of Metadata API: * The Metadata API is specifically designed to manage customization and configuration data in Salesforce. It allows users to deploy, retrieve, create, update, or delete customization information such as custom object definitions, page layouts, and more. * Use in MuleSoft: * When using the Mule Salesforce connector in a Mule application, invoking the Metadata API enables you to programmatically manage and deploy Salesforce metadata. This is essential for tasks such as deploying new custom objects, updating existing configurations, or deleting obsolete customizations. * Why Not Other APIs: * REST API: Primarily used for accessing Salesforce data and interacting with standard and custom objects. * SOAP API: Similar to REST API but uses SOAP protocol; also mainly for data access and manipulation. * Bulk API: Designed for handling large volumes of data for insert, update, delete operations but not for metadata management.
