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 are true about ACLs (Access Control Lists)? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
ACLs can include conditions that must be met for access.
ACLs (Access Control Lists) in ServiceNow are used to enforce security by specifying conditions that must be met for a user to access a record, field, or script. Option A is correct because an ACL defines a condition (typically a script or a set of conditions) that evaluates to true or false, and only when the condition is met is access granted or denied. This is the core mechanism of ServiceNow's role-based and condition-based access control.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

ACLs can be applied to custom tables as well.
✓
ACLs can control read and write access to records.

Common exam traps
Common exam trap: answer the scenario, not the keyword
ServiceNow often tests the misconception that ACLs are client-side or only apply to system tables, but in ServiceNow, ACLs are server-side and apply to all tables, including custom and scoped application tables.
Detailed technical explanation
How to think about this question
ServiceNow ACLs are stored in the 'sys_security_acl' table and are evaluated in a specific order: first by type (record, field, script), then by order (numeric priority). Each ACL contains a condition script that runs server-side using GlideRecord and gs.getUser() to check user roles, groups, or custom logic. A common subtlety is that if no ACL matches a given operation, access is denied by default (implicit deny), which can lead to unexpected access issues if ACLs are not properly scoped.

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.
