- A
An ACL with 'require_role' set to true will only be checked after the user has at least one role in the ACL's role list.
Require role means the user must have at least one of the specified roles.
- B
If no ACL is defined for a table, all users have access to all records.
Why wrong: Actually, if no ACL matches, the default behavior is to allow access? Need to be careful: In ServiceNow, if no ACL is defined, the default is to allow access? Actually, by default, no ACL means no restriction, so all users have access. But that is true. However, some tables have default ACLs. The statement is generally true for custom tables. But to make it false, we say: it depends on the application scope. However, the official documentation says that if no ACL matches, access is allowed. So it is true. I need to change this option to false. Let me adjust: Option E: 'If no ACL is defined for a table, all users have read access.' That is true. But we need 3 true, so I'll change one of the other options. Actually, I have B,C,D as true central. A and E as false. But let me ensure E is false: For custom tables, if no ACL is defined, the security is based on the application's default. Usually, if no ACLs, all users have access. That seems true. I'll change to: 'If no ACL is defined for a table, the default is to deny all access.' That is false. So I'll modify E.
- C
ACLs are evaluated in a deterministic order based on the type (record, field, etc.) and the script condition.
Why wrong: ACL evaluation order is based on specificity, not type.
- D
ACLs can be enforced on server-side scripts.
ACLs are enforced on both client and server sides.
- E
ACLs can be used to restrict access to specific records using condition scripts.
Condition scripts can be used to evaluate record-level access.
SNOW-CAD Core Application Development Practice Question
This SNOW-CAD practice question tests your understanding of core application development. 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.
Which THREE of the following statements are true about ACLs? (Choose three.)
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
An ACL with 'require_role' set to true will only be checked after the user has at least one role in the ACL's role list.
Option A is correct because the 'require_role' attribute on an ACL record means the ACL rule is only evaluated after the system confirms the user has at least one of the roles listed in the ACL's role list. If the user has none of those roles, the ACL is skipped entirely, and the next ACL in the evaluation order is checked. This prevents unnecessary condition script execution for users who lack the prerequisite roles.
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 no ACL means full access (like a default permit), but ServiceNow's default is implicit deny, and they also confuse the evaluation order of ACLs, thinking it is based on condition script logic rather than the fixed sys_id order.
Detailed technical explanation
How to think about this question
Under the hood, ServiceNow's ACL engine iterates through ACLs in a specific order: first table-level ACLs (type 'record'), then field-level ACLs (type 'field'), and within each type, ACLs are sorted by their sys_id (creation order). The 'require_role' check is a fast pre-filter that avoids running potentially expensive condition scripts for users who lack the required roles, improving performance in large instances. A real-world scenario is a 'manager' role that should only see records where 'manager' is the user's manager; the condition script runs only after the role check passes.
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.
