Question 60
An agentic AI adoption exercise reports: A scheduling agent receives appointments in one API using UTC timestamps and another using local times without timezone offsets, then books overlapping meetings after a daylight-saving change. Which dependency is the principal cause of this outcome?
Explanation
Correct Answer
The technical basis is: Interoperating agent tools may represent time differently; ambiguous local timestamps cannot safely be compared with timezone-aware values without a declared interpretation. Resolve this through: Normalize timestamps to a supported timezone-aware representation and require clarification for missing offsets or ambiguous daylight-saving times. The expected evidence is: Boundary fixtures around the clock change preserve appointment order and reject ambiguous or overlapping scheduling requests.
Incorrect Answers
Agentic quality includes the correctness and authorization of intermediate actions, not merely the fluency of the concluding text shown to the user. “Evaluate task outcomes, tool-call traces, idempotency, approval checks and rollback behavior using isolated controlled test fixtures” would remedy that alternative situation, but it would not correct the present issue: interoperating agent tools may represent time differently; ambiguous local timestamps cannot safely be compared with timezone-aware values without a declared interpretation.
“Define an explicit typed mapping that converts currency units, verifies precision and rejects values outside the authorized business range” is the supported response when agent data transformation must respect source and destination units and types; similar field names do not imply interchangeable measurement semantics. Here the decisive response is “Normalize timestamps to a supported timezone-aware representation and require clarification for missing offsets or ambiguous daylight-saving times”, so that different intervention does not meet the stated requirement.
A state-changing autonomous workflow needs traceable identity, tool invocation and approval evidence in addition to the final resource value. “Record the originating user intent, verified principal, exact tool action, result and any human approval alongside a protected change identifier” applies to that other condition. The reported evidence is a scheduling agent receives appointments in one API using UTC timestamps and another using local times without timezone offsets, then books overlapping meetings after a daylight-saving change; this alternative would address the wrong dependency.
