- A
Update sets capture changes to ACLs, but each condition script is captured as a separate record.
Why wrong: ACLs are captured as a whole record, not per condition script.
- B
Update sets must be explicitly exported and then imported into the target instance.
Retrieved or exported from the source instance and committed in the target.
- C
Update sets capture all changes made to an instance, including out-of-box records.
Why wrong: Update sets are designed for customizations, not all changes.
- D
Update sets can contain changes to system properties.
System properties are included in update sets if they are customized.
- E
Update sets are used to move data, such as user records, between instances.
Why wrong: Update sets move configuration and application changes, not data.
Update Sets in ServiceNow
This SNOW-CAD practice question tests your understanding of core application development. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which TWO statements about update sets are correct? (Choose two.)
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
Update sets must be explicitly exported and then imported into the target instance.
The correct answers are B and D. Update sets are used to move customizations between instances. They must be explicitly exported from a source instance and imported into a target instance (B). They can capture changes to system properties (D). Option A is incorrect because update sets capture ACL records as a whole, not individual condition scripts separately. Option C is incorrect because update sets do not capture out-of-box records; they only capture changes made to customizations. Option E is incorrect because update sets move changes (configurations), not data records like users.
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.

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.
Visual reference
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.
