UiPath-ADAv1 Orchestrator and Integration Service Practice Question
A developer needs to configure a queue in Orchestrator to handle invoice processing. The queue must automatically retry failed items up to three times, and unique references must be enforced to prevent duplicate invoices. Which two settings should the developer configure? (Choose two.)
⚠ Common exam trap
Many exam-takers confuse retry interval with retry count, or thinking that queue priority or SLA settings affect retry behavior, when in fact the number of retries is controlled solely by the 'Max # of retries' setting.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable 'Unique Reference' in the queue's unique reference settings.
To automatically retry failed items up to three times, the 'Max # of retries' setting must be set to 3. To prevent duplicate invoices, 'Unique Reference' must be enabled. These two settings directly address the requirements. Other options like retry interval or priority do not control the number of retries or uniqueness, and SLA Prediction is unrelated to these configuration needs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable 'Unique Reference' in the queue's unique reference settings.
Why this is correct
Enabling 'Unique Reference' ensures that each queue item has a unique reference value, preventing duplicate items from being added. This is critical for invoice processing to avoid processing the same invoice multiple times. When a duplicate reference is detected, Orchestrator rejects the item, maintaining data integrity. This setting directly fulfills the requirement to prevent duplicate invoices.
- ✗
Set the 'Auto Retry' interval to 5 minutes in the queue's advanced settings.
Why it's wrong here
The 'Auto Retry' interval setting controls the delay between retry attempts, not the number of retries. While it is useful for spacing out retries, it does not limit the number of attempts. The requirement specifies up to three retries, which is governed by the 'Max # of retries' setting. Setting an interval alone would not enforce the retry count limit.
- ✗
Configure 'Queue Priority' to 'High' to ensure faster retry processing.
Why it's wrong here
Queue Priority affects the order in which items are processed relative to other queues, not the retry behavior. Setting a high priority might expedite processing but does not control the number of retries or uniqueness. This option is irrelevant to the requirements of automatic retries and duplicate prevention. It would not meet the stated needs.
- ✗
Enable 'SLA Prediction' to monitor retry performance.
Why it's wrong here
SLA Prediction is a feature that uses machine learning to predict whether a queue item will breach its SLA, but it does not configure retry attempts or enforce unique references. While it can provide insights, it does not directly implement the required retry count or uniqueness constraints. This option does not fulfill the specific configuration needs for retries and duplicate prevention.
- ✓
Set the 'Max # of retries' to 3 in the queue's retry settings.
Why this is correct
The 'Max # of retries' setting in a queue's retry configuration determines how many times a failed item will be automatically retried before being marked as failed. Setting it to 3 ensures that each item gets three additional attempts after the initial failure. This directly addresses the requirement for automatic retries up to three times, reducing manual intervention and improving success rates for transient errors.
