This SNOW-CAD practice question tests your understanding of working with data. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 admin notices that a business rule on the 'incident' table that sets the 'assigned_to' field based on the caller's manager is not always firing. The rule is set to run 'Before' and 'Update'. What is the most likely reason?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Clue: "always"
Why it matters: Absolute qualifier. An answer using 'always' is only correct if there are genuinely no exceptions — absolute statements are often wrong in networking.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The condition of the business rule is not met because it requires a specific field to change.
Option D is correct because if the field being set is not in the current update, the business rule may not trigger if it depends on a condition. Option A is wrong because the order is not an issue. Option B is wrong because ACLs do not prevent business rule execution. Option C is wrong because async would still fire eventually.
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.
✓
The condition of the business rule is not met because it requires a specific field to change.
Why this is correct
Correct: The rule may check a condition that is not satisfied.
Clue confirmation
The clue words "most likely", "always" in the question point toward this answer.
Related concept
Standard ACLs match source addresses.
✗
The business rule is set to run asynchronously.
Why it's wrong here
Wrong: Async would still execute.
✗
The user lacks the 'incident_edit' ACL.
Why it's wrong here
Wrong: ACLs affect UI, not server-side business rules.
✗
The business rule order is set to 100, making it run too late.
Why it's wrong here
Wrong: Order does not prevent execution.
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.
