Web Application Developer Associate 10.0

Esri Certified Web Application Developer Associates are experienced developing ArcGIS Web applications and are familiar with ArcGIS concepts.

This certification is for Web Developers who have performed tasks as part of team, but don't yet have the experience required to define and lead major projects.

A qualified candidate for the Esri Web Application Developer Associate Certification will be familiar with ArcGIS concepts and be aware of performance considerations for building Web applications. The candidate should be familiar with using object-oriented programming, as well as application documentation, maintenance, troubleshooting, and support.

A qualified candidate should be able to:

  • Identify ArcGIS geometry types, relationships, and operations
  • Define map and layer concepts and their applications in development
  • Understand relevant performance implications
  • Understand service configuration for out of the box services
  • Use services via REST and SOAP
  • Work with maps and layers, and other visualization elements
  • Use Web API tools
  • Work with secured services
  • Troubleshoot Web applications
  • Deploy Web applications

The following list of skills measured is provided to familiarize candidates with topics covered on the exam and to help guide exam preparation. We recommend candidates review this list and assess their knowledge of each skill. Specific preparation resources are available to assist with refreshing in areas where any knowledge gaps are found.

  • Explain how to activate or deactivate the Draw and Edit Toolbars
  • Explain the difference between the Edit Tool and Editor component and when to use each
  • Explain the process for working with attachments
  • Identify the edit data operations available via the Web APIs
Security Implementation
  • Explain how to consume secure map services and tasks via the web APIs
  • Explain the various reasons for using a proxy page to manage service calls
  • Explain the role of security in client side editing
  • Explain how to connect to a secured service
  • Explain how to dynamically request a token using best practices
  • Explain how to generate a token from the token page
Troubleshooting
  • Explain where to locate ArcGIS Server logs, how to interpret standard Esri log messages, and how to set log level appropriately
  • Explain how to verify that a service is operational
  • Determine which tools to use for troubleshooting
  • Explain how to troubleshoot REST cache that is in an invalid state
  • Explain how to check task results using the REST directory
