The answer is to use scheduled imports instead of manual imports and to disable business rules and ACLs during the import process. Scheduling imports during off-peak hours reduces system contention by shifting heavy processing to low-activity windows, while disabling business rules and ACLs eliminates unnecessary record-level evaluations that can exponentially slow data ingestion. This question tests your understanding of import set performance optimization best practices, a key topic on the ServiceNow Certified Application Developer CAD exam where you must distinguish between actions that reduce load versus those that risk data integrity. A common trap is choosing to enable auditing or run imports during business hours, which actually degrades performance. Remember the memory tip: “Schedule and disable” — schedule the import for off-peak times and disable non-essential processing rules to keep the pipeline fast and clean.
SNOW-CAD Integrating and managing application data Practice Question
This SNOW-CAD practice question tests your understanding of integrating and managing application data.

Correct answer & explanation
✓
Disable business rules and ACLs during import.
Scheduling imports during off-peak hours reduces load on the system. Disabling business rules and ACLs during import speeds up processing by avoiding unnecessary checks.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Disable business rules and ACLs during import.
Why this is correct
This reduces overhead and speeds up import significantly.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Standard ACLs match source addresses.
✗
Increase the import set table row limit.
Why it's wrong here
Row limit does not affect performance; it only caps the number of rows.
✗
Enable 'Create multiple' for transform maps.
Why it's wrong here
'Create multiple' is for splitting rows, not general performance optimization.
✗
Use a single transform map for all records.
Why it's wrong here
Using multiple transform maps may be necessary for different record types.
✓
Use scheduled imports instead of manual imports.
Why this is correct
Scheduled imports can be run during low-usage times.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Standard ACLs match source addresses.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
Standard ACLs match source addresses.
Extended ACLs can match source, destination, protocol and ports.
The first matching ACL entry is used.
There is usually an implicit deny at the end.
TExam Day Tips
→Check inbound versus outbound direction.
→Read the ACL from top to bottom.
→Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related SNOW-CAD ACL questions on filtering logic and placement.
