- A
The user also has a role that denies access.
Why wrong: There is no deny role in ACLs; roles only allow.
- B
The update operation requires a specific condition script that returns false.
A script condition returning false denies access.
- C
The record is locked by another user.
Why wrong: Record locking is not enforced by ACLs.
- D
Another ACL on the same table denies write access.
A more specific ACL can deny even if this one allows.
- E
The ACL is set to 'Create' instead of 'Write'.
Why wrong: The ACL type is separate; if it were create, it wouldn't affect update.
Question 36 of 520
ACL Denied Despite Role: Check Condition Script and Other ACLs
This SNOW-CSA practice question tests your understanding of application rules, acl and notifications. 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.
An ACL on the Task table has a role condition requiring the 'itil' role. A user with the 'itil' role is trying to update a task but is denied. Which TWO factors could be causing this? (Select 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
✓
The update operation requires a specific condition script that returns false.
Option B is correct because even if the role condition is satisfied, a condition script on the ACL can independently evaluate to false, denying the update. Option D is correct because multiple ACLs on the same table are evaluated; if any other ACL explicitly denies write access, the overall result is denial, regardless of the role condition.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume satisfying the role condition is sufficient for access, but they overlook that condition scripts and other ACLs on the same table can independently deny the operation.
Detailed technical explanation
How to think about this question
ACLs in ServiceNow are evaluated in order of priority; if any ACL denies access, the operation is blocked. Condition scripts can include complex logic (e.g., checking state, assignment group) and run after role checks. A common real-world scenario is a condition script that checks if the task is in a specific state (e.g., 'Closed Complete') and returns false for updates, overriding the role permission.
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 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.
