Exam AB-410 Topic 1 Question 8 Discussion

Explanation:
401 errors - Reauthenticate connection; Duplicate executions - Enable concurrency control

A 401 response indicates that the connector call is unauthorized, commonly because a connection token expired, credentials changed, consent was revoked, or the connection reference points to an invalid connection. Reauthenticating the connection renews the credential context and is the direct corrective action.
Increasing timeout or changing retry policy cannot convert an unauthorized request into an authorized one.
Duplicate executions require control over simultaneous flow runs. Enabling trigger concurrency control and setting an appropriate degree of parallelism prevents overlapping instances from processing the same event at the same time. The maker should also examine trigger conditions, polling behavior, and idempotency keys, because concurrency control alone cannot correct every duplicate-trigger design. Adding a delay merely shifts execution time, and retry policy addresses transient action failures rather than independent duplicate runs.
After correcting both issues, failed runs should be resubmitted only where the actions are safe to repeat. The Study Guide includes "test and troubleshoot cloud flows." The mappings target the actual failure classes:
restore authentication for 401 errors and govern parallel runs for duplicate execution.
