SNOW-CSA Application Rules, ACL and Notifications Practice Question
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 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.
Options A and D are correct. A condition script that returns false would deny access. Another more specific ACL that denies access would take precedence. Option B is wrong because roles do not deny; they allow. Option C is wrong because the user has the required role. Option E is wrong because record locking is not ACL-related.
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 user also has a role that denies access.
Why it's wrong here
There is no deny role in ACLs; roles only allow.
✓
The update operation requires a specific condition script that returns false.
Why this is correct
A script condition returning false denies access.
Related concept
Standard ACLs match source addresses.
✗
The record is locked by another user.
Why it's wrong here
Record locking is not enforced by ACLs.
✓
Another ACL on the same table denies write access.
Why this is correct
A more specific ACL can deny even if this one allows.
Related concept
Standard ACLs match source addresses.
✗
The ACL is set to 'Create' instead of 'Write'.
Why it's wrong here
The ACL type is separate; if it were create, it wouldn't affect update.
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-CSA ACL questions on filtering logic and placement.
