UiPath-ADAv1 UI Automation and Object Repository Practice Question
An automation project requires interacting with a dynamic web application where UI elements frequently change their ID attributes. Which approach best ensures long-term selector stability within the Object Repository?
⚠ Common exam trap
Candidates often attempt to manually repair broken selectors one by one. They fail to implement anchored selectors, which would provide a permanent solution to dynamic ID changes in the application.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement anchored selectors or relative positioning within the Object Repository.
Anchors leverage stable, non-changing elements nearby to locate a target, effectively insulating the automation from ID volatility. By utilizing Anchor Base or fuzzy selectors within the Object Repository, developers decouple target identification from fragile attributes. This practice is foundational for robust UI automation, as it reduces maintenance overhead and minimizes runtime failures caused by minor front-end updates, ensuring the bot remains reliable even when the application's underlying HTML structure undergoes frequent, non-functional modifications.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Hardcode the full selector string including the dynamic ID to ensure precision.
Why it's wrong here
Hardcoding dynamic IDs is a poor practice because these values change with each session or page refresh. This results in immediate selector failure during runtime. Relying on volatile attributes defeats the purpose of the Object Repository and requires manual intervention for every update, which is highly inefficient for production bots.
- ✗
Use the 'Find Children' activity to iterate through all elements on the page.
Why it's wrong here
Iterating through all children using 'Find Children' is computationally expensive and slow for finding a single element. It adds unnecessary complexity to the workflow and increases execution time significantly. This approach ignores the structural context provided by anchors, making it an inferior choice for locating specific, unique UI elements.
- ✓
Implement anchored selectors or relative positioning within the Object Repository.
Why this is correct
Anchors provide a reliable way to identify a target element based on its spatial relationship to a stable reference point. By configuring these in the Object Repository, developers create reusable, resilient descriptors. This method effectively masks the instability of dynamic attributes, ensuring the automation remains functional despite changes to element IDs.
- ✗
Disable the Object Repository and use basic Click activities with default settings.
Why it's wrong here
Disabling the Object Repository removes the benefits of centralized element management and reusability. Default settings often rely on static selectors that fail when IDs change. Without a centralized repository, maintaining selectors across multiple workflows becomes a difficult task, leading to high technical debt and inconsistent automation performance across the enterprise.
