The answer is to create ACLs on the table to restrict read access to HR users and to extend the task table. This is correct because extending the task model inherits essential assignment and state fields, while Access Control Lists (ACLs) enforce record-level security by defining exactly which users or roles can read the data. On the ServiceNow Certified Application Developer CAD exam, this scenario tests your understanding of extending task and access control together—a common integration point where candidates forget that extending a table does not automatically grant or restrict permissions. A frequent trap is assuming that extending task alone handles security, but ACLs are always required to enforce read restrictions. For web service accessibility, the table must also have the “Allow web service access” property enabled on its table definition. Remember the mnemonic: “Extend for fields, ACL for shields.”
SNOW-CAD Creating and customizing tables and data Practice Question
This SNOW-CAD practice question tests your understanding of creating and customizing tables and data. 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.
A developer needs to create a new table that will store confidential employee feedback. The table must have the following characteristics: (1) Only authorized HR users can read the records. (2) The table should use the 'task' model to leverage assignment and state fields. (3) The table should be accessible via web services for integration. Which TWO actions are required to meet these requirements?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Extend the 'task' table
Option D is correct because extending the 'task' table allows the new table to inherit the assignment and state fields required by the 'task' model. This is the standard approach in ServiceNow for creating tables that leverage task-related functionality, such as assignments and workflow states.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
Enable the 'Allow web service access' property on the table
Why it's wrong here
Web service access is controlled by ACLs, not a table property.
✓
Extend the 'task' table
Why this is correct
Task provides assignment and state fields.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the 'Allow web service access' property with a security control, when in fact it only enables the endpoint and does not restrict access; proper ACLs are required to enforce read restrictions.
Detailed technical explanation
How to think about this question
In ServiceNow, extending the 'task' table (sys_db_object) provides automatic inheritance of core fields like 'assigned_to', 'state', 'priority', and 'assignment_group', which are essential for task-based workflows. ACLs (Access Control Lists) are the primary mechanism for enforcing read restrictions; they evaluate conditions like 'hr_user' role membership at the database level, ensuring only authorized HR users can query records via UI or web services. The 'Allow web service access' property is a table-level flag that, when enabled, permits SOAP and REST API access, but it must be combined with proper ACLs to enforce authorization.

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.
