C_CPI Practice Test 6 — 10 Questions

Question 1

An integration developer is building an integration flow in SAP Cloud Integration that must process messages in a strict sequence. Multiple messages arrive at the same time from an HTTPS sender, and the developer needs the flow to execute only one message at a time, in the exact order they were received. Which configuration should be applied?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Set the runtime configuration of the integration flow to 'Sequential Processing' and set the maximum number of concurrent executions to 1.. To enforce that an integration flow processes messages one at a time and in the order received, the runtime configuration must be set to sequential processing with a maximum concurrency of 1. This is a property of the integration flow itself, not of the sender adapter or any step within the flow. The other options address delivery guarantees, message splitting, or queue behavior, none of which control the flow's runtime concurrency.

Answer

Configure the sender adapter to use 'Best Effort' quality of service and enable message ordering.

Answer

Enable the 'Exclusive' option in the JMS queue configuration of the sender adapter.

Answer

Add a 'Splitter' step with sequential processing enabled at the start of the integration flow.

Question 2

An integration developer needs to expose a SOAP-based web service from SAP Cloud Integration. The service must validate incoming messages against an XSD schema and reject invalid messages with a SOAP fault. Which step should be used in the integration flow to perform the validation?

Accepted Answer

XML Validator step. The XML Validator step is specifically designed to validate XML payloads against an XSD schema. When validation fails, it raises an exception that can be handled in an Exception Subprocess to return a SOAP fault. This ensures that only messages conforming to the defined schema are processed, meeting the requirement to reject invalid messages with a proper SOAP fault.

Answer

Schema Validation step

Answer

XSD Check step

Answer

Message Mapping step with XSD validation

Question 3

An integration developer is creating an integration flow in SAP Cloud Integration that receives an IDoc from SAP S/4HANA and must transform it into a JSON structure for a third-party logistics provider. The developer has already imported the IDoc XSD into the integration flow's resources. Which mapping approach should be used to convert the IDoc XML into the target JSON?

Accepted Answer

A Message Mapping followed by an XML-to-JSON converter step. Converting an IDoc into a partner-specific JSON document involves two distinct concerns: reshaping the IDoc hierarchy into the target structure, and serializing XML into JSON syntax. A Message Mapping handles the structural transformation using the imported IDoc XSD, producing intermediate XML that reflects the desired layout, and the XML-to-JSON converter then emits valid JSON. Mapping straight to JSON, or converting the raw IDoc without restructuring, does not produce the contracted format.

Answer

An XML-to-JSON converter applied directly to the raw IDoc payload

Answer

A Message Mapping whose target is defined by a JSON schema artifact

Answer

A single XSLT mapping that outputs JSON directly as text

Question 4

An integration flow uses a multicast step with two branches. The first branch writes to an SFTP server and the second branch sends an alert email. The developer observes that when the SFTP write fails, the email is never sent. Which multicast configuration change ensures the email branch still executes when the SFTP branch fails?

Accepted Answer

Disable 'Stop on Exception' on the multicast so remaining branches continue after a branch fails.. The multicast step's 'Stop on Exception' option controls whether a failing branch aborts the remaining branches. Disabling it makes the runtime process each branch independently, logging the failure of the SFTP branch while still executing the email branch. This isolation is what guarantees the alert is sent despite the SFTP error.

Answer

Enable 'Stop on Exception' on the multicast and add an Exception Subprocess to the flow.

Answer

Wrap the SFTP branch in a Local Integration Process and set its quality of service to Exactly Once.

Answer

Change the multicast to sequential processing and set the SFTP branch as the first route.

Question 5

An integration developer needs to convert a CSV payload into XML within an integration flow in SAP Cloud Integration. The CSV has a header row and comma delimiters. Which step should be used?

Accepted Answer

CSV to XML Converter. To convert CSV to XML, the dedicated CSV to XML Converter step is used. It parses the CSV based on configured delimiter and header settings and produces an XML representation. Other steps like XML to CSV Converter do the reverse, Message Mapping requires XML input, and Content Modifier does not perform format conversion.

Answer

XML to CSV Converter

Answer

Message Mapping

Answer

Content Modifier

Question 6

You are designing an integration flow that must split an incoming XML message containing multiple order items into individual messages, process each item separately, and then aggregate the results into a single response. Which pair of flow steps should you use to achieve this?

Accepted Answer

Splitter and Gather. To process each order item separately and then combine the results, the integration flow must split the incoming message into multiple messages, process them, and then gather them back. The Splitter step performs the split, and the Gather step performs the aggregation. Other steps like Router, Multicast, or Content Modifier do not change message cardinality in the required way.

Answer

Content Modifier and Message Mapping

Answer

Router and Multicast

Answer

Iterating Splitter and Join

Question 7

An integration developer is using a Groovy script in SAP Cloud Integration to parse a large XML payload. The script uses XmlSlurper to navigate the XML. During testing, the developer notices that the script consumes excessive memory and sometimes throws OutOfMemoryError. Which approach should be taken to mitigate this issue?

Accepted Answer

Use a streaming approach with StAX (Streaming API for XML) to parse the XML incrementally.. For large XML payloads, using a streaming parser like StAX is the most memory-efficient approach. StAX reads the XML sequentially, allowing the script to process elements on the fly without building an in-memory tree, thus avoiding OutOfMemoryError.

Answer

Increase the script's memory allocation by setting the 'scriptMemory' parameter in the integration flow.

Answer

Replace XmlSlurper with XmlParser to improve memory efficiency.

Answer

Convert the XML to JSON using a Message Mapping step before processing in Groovy.

Question 8

An integration developer is creating an integration flow that must convert a JSON payload to XML. The JSON contains an array of objects under the root element 'orders'. Which step should be used to perform this conversion?

Accepted Answer

JSON to XML Converter step.. The JSON to XML Converter step is a built-in feature in SAP Cloud Integration that converts JSON payloads to XML. It is the simplest and most direct method, requiring no custom scripting or mapping. It correctly handles arrays and nested structures, making it ideal for this scenario.

Answer

Content Modifier step with a JSON to XML expression.

Answer

Groovy script step using JsonSlurper and XmlBuilder.

Answer

Message Mapping step with a JSON to XML mapping.

Question 9

An integration developer needs an integration flow in SAP Cloud Integration to call an external REST API that requires an OAuth 2.0 client credentials token. The token endpoint and client credentials are stored as a Security Material of type OAuth2 Client Credentials. Which step configuration correctly obtains and attaches the token to the outbound request?

Accepted Answer

Add a Request Reply step with the HTTP receiver channel configured to use the OAuth2 Client Credentials security material, so the adapter fetches and applies the token automatically.. The HTTP receiver adapter can consume an OAuth2 Client Credentials security material directly. During message processing it requests a token from the configured token endpoint and injects the bearer token into the Authorization header, so the developer does not need custom scripting. This is the supported and least error-prone configuration.

Answer

Add a Request Reply step with the SOAP receiver channel configured to use the OAuth2 Client Credentials security material.

Answer

Add a Content Modifier that sets an Authorization header with a Basic authentication value derived from the client ID and secret.

Answer

Add a Groovy script that reads the client credentials from a Partner Directory entry, performs a POST to the token endpoint, and sets the Authorization header manually.

Question 10

Refer to the exhibit. You are using the XML-to-JSON converter in an integration flow. Based on the error log, what is the most appropriate action to resolve this issue?

Accepted Answer

Use an XSLT Mapping to wrap the XML content in a single root tag.. The XML-to-JSON converter strictly requires a single root element to map the structure into a valid JSON object. When multiple root elements are present, the converter cannot determine the JSON hierarchy. Addressing this via an XSLT mapping or a Content Modifier before the conversion ensures compliance with JSON specifications, which is a common requirement when integrating between XML-based SAP systems and JSON-consuming external cloud applications.

Answer

Increase the message size limit in the tenant settings.

Answer

Change the Content-Type header to application/xml.

Answer

Disable the 'Use Namespaces' option in the converter.
