This SNOW-CAD practice question tests your understanding of working with data. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An administrator notices that a scheduled job, 'Update Asset Status', fails every night with a 'Script timeout' error. The job updates a large number of records in the Asset table. Which approach should the administrator take to resolve the timeout issue?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Rewrite the job to use GlideAggregate with query and update in bulk
Option D is correct because the script timeout error indicates that the scheduled job is taking too long to process individual record updates. Rewriting the job to use GlideAggregate with bulk update operations reduces the number of database round-trips and processes records in batches, which is the standard approach for handling large data sets in ServiceNow without hitting script timeout limits.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Add a business rule to run asynchronously for each update
Why it's wrong here
Business rules run on each record, not solving the timeout of the job itself.
✗
Increase the timeout value in the scheduled job configuration
Why it's wrong here
This only delays the failure, not solving the root cause.
✗
Split the job into multiple smaller jobs running sequentially
Why it's wrong here
More complex to manage and still may timeout if each job processes many records.

Common exam traps
Common exam trap: answer the scenario, not the keyword
ServiceNow often tests the misconception that increasing timeouts or splitting jobs is a valid fix, when the correct answer always involves using bulk database operations like GlideAggregate to reduce processing overhead.
Detailed technical explanation
How to think about this question
GlideAggregate allows you to perform aggregate functions and bulk updates directly on the database server using a single SQL query, bypassing the need to load each record into the application scope. This is particularly effective for large tables because it minimizes script execution time and reduces the risk of hitting the default 10-minute script timeout. In real-world scenarios, administrators often combine GlideAggregate with GlideRecord's setWorkflow(false) and setUseEngines(false) to further optimize bulk updates.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the SNOW-CAD exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
