MB-920 Practice Question: Refer to the exhibit
Exhibit
Refer to the exhibit. Job: Process inventory reservation Status: Ended Recurrence: Every 5 minutes Last run time: 11:45 AM Current time: 12:30 PM Next scheduled run: 12:50 PM Exhibit: A Dynamics 365 Commerce batch job status screen.
Refer to the exhibit. A company uses the 'Process inventory reservation' job to manage inventory reservations for online orders. The job is scheduled to run every 5 minutes. At 12:30 PM, a customer places an order but the inventory reservation is not created until 12:50 PM. What is the most likely cause of this delay?
⚠ Common exam trap
Candidates may assume that scheduled batch jobs always start on time, but when the job duration exceeds the recurrence interval, subsequent runs are delayed, leading to a processing backlog.
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
✓
The job is set to run every 5 minutes but it takes 20 minutes to process.
The 'Process inventory reservation' job is scheduled to run every 5 minutes, but if a single run takes 20 minutes to complete, the job will not start its next run until the current run finishes. Therefore, an order placed at 12:30 will be queued and processed only after the current run finishes at 12:50, resulting in a 20-minute delay.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The job is not configured to process reservations for online orders.
Why it's wrong here
The job is specifically used to process reservations for online orders, so it is configured for that purpose.
- ✗
The job failed during the last run.
Why it's wrong here
A failed job run would likely cause an indefinite delay or error, not a consistent 20-minute delay.
- ✓
The job is set to run every 5 minutes but it takes 20 minutes to process.
Why this is correct
This is correct. The job's processing time exceeds its recurrence interval, causing a backlog that delays subsequent runs.
- ✗
The job only processes reservations at its scheduled times, so the order will be processed at 12:50 PM.
Why it's wrong here
The job runs every 5 minutes, so the next scheduled run after 12:30 is at 12:35, not 12:50. The 20-minute delay is due to job duration, not the schedule itself.
