The correct choice is to use GlideRecordBatch or a scheduled job to process records in smaller batches. This approach directly addresses the batch processing large data import timeout issue by breaking the 100,000-record load into manageable chunks, each completing within the 60-second script timeout limit. GlideRecordBatch handles asynchronous, incremental processing, allowing the migration to finish without interruption. On the ServiceNow Certified Application Developer CAD exam, this question tests your understanding of platform governor limits and efficient data handling—a common trap is thinking you can simply increase the timeout or use setLimit, but those either bypass the root cause or skip required records. Remember the memory tip: “Batch it, don’t stretch it”—chunking large imports prevents timeouts while preserving data integrity.
SNOW-CAD Working with Data Practice Question
This SNOW-CAD practice question tests your understanding of working with data. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
During a data migration, a developer runs a GlideRecord query to load 100,000 records from an external source into the 'incident' table. The script times out after 60 seconds. Which optimization technique would be most effective to avoid the timeout?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use GlideRecordBatch or a scheduled job to process records in smaller batches.
Option D is correct because using GlideRecordBatch or a scheduled job with incremental processing breaks the workload into manageable chunks, preventing timeout. Option A is wrong because increasing timeout is a workaround, not efficient. Option B is wrong because setLimit reduces the number of records, but data migration requires all records. Option C is wrong because GlideAggregate is not for inserts.
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.
✗
Use setLimit(1000) to reduce the number of records per execution.
Why it's wrong here
Wrong: This would migrate only a subset.
✗
Use GlideAggregate to count records before insertion.
Why it's wrong here
Wrong: Counting does not help with insertion timeout.
✗
Increase the transaction timeout setting in the system properties.
Why it's wrong here
Wrong: This is a temporary fix and may cause other issues.
✓
Use GlideRecordBatch or a scheduled job to process records in smaller batches.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
