Exam Structure The exam consists of 60 questions delivered in a 90-minute period.

The following table shows the Learning domains measured by this exam and the percentage of questions represented in each domain. About Questions and Responses For each question on the examination, there are four (4) possible responses. The person taking the exam reviews the response options and selects the most correct answer to the question. A wrong answer, called a distractor, is an incorrect answer a candidate with incomplete skill or knowledge may choose. A distractor is a plausible option that fits into the topic area defined by a test objective, but is not the correct response. Questions are presented in one of these formats. Multiple-Select (one or more answers) An examinee selects at least one response that accurately answers the question. These questions use the phase “Select all that apply” to indicate that there may be more than one correct response. Multiple Choice (single answer) An examinee selects one response that most accurately answers the question. True or False An examinee is presented with a statement and is asked to select the correct answer from the two options; the statement is either true or false. The Testing Process Each candidate must register for the exam. During the registration process, each test taker has the option of taking the exam at an Authorized Testing Center or as an online-proctored exam. In both testing venues, the Certified Application Developer exam is done through a consistent, friendly, user interface customized for ServiceNow tests. The Kryterion Testing Network (KTN) is worldwide and all locations offer a secure, comfortable testing environment. Candidates register for the exam at an exact date and time so there is no waiting and a seat is reserved in the testing center. Each candidate can also choose to take the exam as an online-proctored exam. This testing environment allows a candidate to take the test on his or her own system. Access to a web browser, a webcam, and broadband access to the Internet is required.

Learning Domain 5 – Working with External Data

A. Import data in CSV or Excel format

Response In Theory: 1. Decide data source, is data coming from Excel, CSV, XML, JDBC or HTTP/FTP? 2. Create a ‘Transform Map’ , then ‘Run’ or ‘Schedule’ an Import.

Create Data Source – [Navigate to System Import Sets > Data Sources.] – (Create a data source record to define what data an import set should import.):

Select the type of data you are importing, such as from a remote File, a JDBC database, or using LDAP.

Data source fields – Additional fields appear on the data source form depending on the value of the Type field. (These additional fields appear on the data source form when the Type field value is File.) – This is where you specify configuration depending on file. Format Select one of the following formats from the list: CSV, CSV (tab), Excel, XML.

Create a Transform Map [Navigate to System Import Sets > Create Transform Map.] – Every import operation to an EXISTING system table requires a transform map (decides what column in source data that should be paired with the target table).

Automatic Mapping Utility (if already same name system will map for you)
The simplest mapping method is where all of the field names of the import sets match the names of the fields on the production tables onto which the data will be transformed. In this case, simply click Auto map matching fields in the related list in the Table Transform Map form and confirm proper matching. If there are any discrepancies in terms of how fields were automatically matched, use the mapping assist utility to correct them. When all fields are matched properly, click the Transform related link to begin transforming data onto the destination table.

Mapping Assist Utility (GUI that helps you manually pair source and target data)
The mapping assist utility provides a visually intuitive environment for specifying mapping between import set fields and production table fields. The mapping assist utility makes it possible to map a single source field (field on an import set table) to multiple destination fields (fields on a production table).

Create a field map [Navigate to System Import Sets > Transform Maps.] – The field map determines what values from the source table the transformation adds to the target table. These are the rules around when and how data should be transferred when the import is run. Examples:

Choice Action:

This field is available if the target field is a choice list or reference field. This field specifies what to do if the import set contains a reference or choice value other than those available. Select one of these options:

create: Create a new choice or record in the reference table.
ignore: Ignore the new value from the source table.
reject: Skip the entire row (record) containing the new value and continue to the next row.

Referenced Value Field Name:

When the target field is a reference field, the transform map needs a way to match incoming source values to existing records in the reference field’s source table. Since most imports do not provide a 32-character sys_id value, you must specify a column from the reference field’s source table that contains values that match the incoming source values.
When there is a matching record, the transform map stores the sys_id of the matching record in the target field. If there is no matching record, the transform map creates a new record in the reference field’s table and stores the sys_id of the new record in the target field.

B. Integrate to, including testing and debugging, an external data source using SOAP

https://docs.servicenow.com/bundle/jakarta-platform-administration/page/integrate/vendor-specific-integrations/reference/r_SupportedIntegrationInterfaces.html

The SOAP Web Services provided by ServiceNow are WS-I compliant, as outlined in the WS-I Basic Profile 1.0.

Concepts and Terminology

• Provider – publishes web service for clients to invoke (consume)
• Consumer – invokes / consumes published web service
• Standards
  • WSDL
    • Web Service Description Language
    • XML document describing functions, arguments, data schema, and endpoint (where / how to invoke the service, URL)
    • WSDL only necessary when generating SOAP envelope programmatically
  • SOAP
    • Simple Object Access Protocol
    • XML document usually HTTP posted to web service endpoint described in WSDL
    • SOAP:Envelope / SOAP:Header / SOAP:Body
  • HTTP
    • Hyper-Text Transfer Protocol
    • POST vs GET – Web Service is POSTed
    • XML vs. Form POST – Web Service is XML

Web Service Provider

ServiceNow publishes its underlying table structures and associated data with the following Web Service methods:

• Direct Web Services: Use a URL query to request a ServiceNow table’s WSDL.
• Web Service Import Sets: Use import tables and transform maps to automate Web Service requests to ServiceNowtables.
• Scripted Web Services: Use custom JavaScript to execute Web Services requests.

Note: SOAP messages are sent with the assumption that the recipient is XML compliant. No encoding is applied to the SOAP message. SOAP always decodes responses as UTF-8, the XML encoding header is not used.

C. Integrate to, including testing and debugging, an external data source using REST

https://docs.servicenow.com/bundle/jakarta-platform-administration/page/integrate/concept/c_IntegrationOptions.html

REST (REpresentational State Transfer) is a simple stateless architecture that generally runs over HTTP.

The REST style emphasizes that interactions between clients and services are enhanced by having a limited number of operations. Flexibility is provided by assigning resources their own unique universal resource indicators (URIs). Because each operation (GET, POST, PUT, and DELETE) has a specific meaning, REST avoids ambiguity.

The REST API is active by default in all instances.

RESTful web services offer administrators several advantages, including:

• Support for different HTTP methods to perform different actions
• Detailed response codes and header information
• Pagination support for large data sets
• Streaming data on GET requests

The Automated Test Framework supports Inbound REST test steps. You can create automated tests for custom Inbound REST APIs that you create. Creating tests for your custom REST APIs simplifies upgrade testing, and makes it possible to verify modifications to a REST API are backward compatible. See Administering REST test step configurations and ATF REST test step configurations.
