AD0-E213 Adobe Analytics Developer Professional Exam Free Practice Exam Questions (2025 Updated)

This exception indicates that a JavaScript object was expected but was not provided. This can happen when a variable is referenced without being defined, or when a parameter is expected but not provided. For more detailed information, please refer to the Mozilla Developer Network documentation (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Not_non-null_object).

In Adobe Analytics, thedigitalDataobject is used to pass data to the Analytics server. ThedigitalDataobject is a JavaScript object that contains a number of properties and methods that can be used to populate data for Analytics tracking.

In this case, the developer needs to track page views on the retail website and populate the page name for each web page. ThedigitalData.page.pageNameproperty can be used to accomplish this. ThedigitalData.pageobject is used to pass data about the current web page to Analytics, and thepageNameproperty is used to specify the name of the current web page.

For example, the following code can be used to set thedigitalData.page.pageNameproperty to the name of the current web page:

digitalData.page.pageName = "Home Page";

This will set thepageNameproperty of thedigitalData.pageobject to "Home Page", which will be sent to the Analytics server along with other data about the current web page.

This technique is used to send data over HTTP to a web server when the useBeacon variable is enabled. According to the Adobe Analytics Developer Professional study guide (page 8-9), the navigator.sendBeacon() method is a modern way of sending data to a web server in the background that is asynchronous and does not interfere with the user's experience. For more detailed information, please refer to the study guide

CORS is a web security method that allows for limited cross-domain communication and is supported by Experience Cloud ID. It enables web applications to access resources located on a different domain than the one from which the request originated. This is important for ensuring that web applications are secure and that data is not leaked to malicious actors. CORS is implemented by setting certain headers on the server, allowing the web application to access resources from different domains. Additionally, CORS can also be used to authenticate users, allowing for secure access to resources.

After the tracking call runs, the s.useBeacon variable resets to false and must be set to true in order for the beacon to be sent on the next tracking call. This is described in the Adobe Analytics documentation (https://docs.adobetag.com/analytics/implementation/vars/usebeacon/).

Authors can use nested launches to avoid repetitive work in various places of their websites. A nested launch is a launch that is created inside of another launch, and can be used to share common settings between multiple launches. For example, if an author needs to use the same set of rules in multiple places of their website, they can create a single launch with those rules, and then nest it inside of other launches that need to use those rules. This is an efficient way of avoiding having to repeat the same work in multiple places.

In order to troubleshoot an implementation, the professional should work with the organization's website owners to ensure that all JavaScript errors are resolved. This is because JavaScript errors can prevent data from being sent to Adobe's servers, which can cause the debugger to not show any data. For more detailed information, please refer to the Adobe Analytics Developer Professional study guide (page 8-9).

According to the Adobe Analytics Developer Professional study guide, the set of action types available in the Analytics extension are Set Variables, Send Beacon, and Clear Variables. These actions allow you to define and set variables, send a request to Adobe Analytics, and clear variables when necessary.

When building a rule in Launch by Adobe, the correct order to follow is Event, conditions, exceptions, and then actions. This order ensures that the conditions and exceptions will be evaluated before any of the actions in the rule are triggered. This is referenced in the Adobe Analytics Developer Professional study guide section on the Tag Management System.

A random number data element is often used for sampling data in the Adobe Experience Platform. This data element generates a random number between 0 and 1, which is then used to select a given sample size. This is referenced in the Adobe Analytics Developer Professional study guide section on the Tag Management System.

This code should be added to the doPlugins() function in order to prevent the tracking call from being sent to Adobe. Specifically, setting s.abort to true will stop the tracking call from being sent, while setting it to false will allow the tracking call to be sent. This is described in the Adobe Analytics documentation (https://docs.adobetag.com/analytics/implementation/general/variables/abort/).

Launch by Adobe is a tag management system that allows users to manage marketing and analytics tags on their website from a single location. Launch provides a user-friendly interface that allows users to create rules to specify when and where tags should be fired, and to manage the data that is passed to these tags.

In addition to managing tags, Launch can be used to take certain actions on web pages, such as modifying page content or user interfaces, sending data to third-party tools, or triggering events in response to user behavior.

Launch can also be used to manage the lifecycle of tags, including versioning, testing, and deployment. By using Launch, users can improve the efficiency and accuracy of their tag management, reducing the risk of errors and improving the speed of their website.

Creating a copy of source pages and classifying content within a website are not primary functions of Launch, although it may be possible to use Launch to accomplish these tasks in certain contexts.

A datalayer is an object that contains the data that needs to be communicated to digital analytics and reporting servers. It is typically a JavaScript object that contains key-value pairs that represent the different data points that need to be sent to the reporting server. For more information, please refer to the Adobe Analytics Developer Professional study guide.

The scenarios that would justify the use of the feature "processing rules" in Adobe Analytics are A and D. Processing rules allow users to define conditions and actions to transform data as it enters the reporting interface. In scenario A, processing rules can be used to map the context variable to eVar/props. In scenario D, processing rules can be used to fix the historical values captured in the pages report. Details can be found in the Adobe Analytics Developer Professional study guide.
