Quick Answer
The answer is an address group. This is the correct choice because an address group allows an administrator to group multiple subnets into a single object, which can then be referenced directly in a security policy rule. By using an address group, you avoid having to create separate source entries for each subnet, drastically simplifying rule management and making the policy easier to maintain and audit. On the Palo Alto Networks Certified Network Security Administrator PCNSA exam, this concept tests your understanding of object-based policy design, often appearing in questions about reducing rule complexity or consolidating overlapping address ranges. A common trap is confusing address groups with dynamic address groups—remember that static address groups require manual membership, while dynamic groups use tags. A useful memory tip: think of an address group as a “folder” for your subnets—just as a folder keeps related files together, an address group keeps related subnets together in one rule.
This PCNSA practice question tests your understanding of managing objects. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 administrator needs to allow traffic from multiple subnets to a specific internal server. The subnets are all part of the same address group. Which object would simplify the security policy rule?
Tag
Why wrong: Tags are for grouping and identification, not for defining source addresses.
Schedule
Why wrong: Schedules define time-based access, not addresses.
Service group
Why wrong: Service groups group ports/protocols, not addresses.
Address group
Address groups combine multiple address objects, simplifying policy creation.

Correct answer & explanation
Address group
Option D is correct because an address group allows the administrator to group multiple subnets into a single object, which can then be referenced in a security policy rule. This simplifies rule management by reducing the number of individual source address entries needed, making the policy easier to maintain and audit.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
The trap here is that candidates may confuse address groups with service groups, thinking both are used for grouping, but service groups only apply to ports/protocols, not IP addresses or subnets.
Detailed technical explanation
Address groups in Palo Alto Networks firewalls can be static (manually defined) or dynamic (populated via external sources like Active Directory or IP tags). When a security rule references an address group, the firewall evaluates the source IP against all member addresses at the time of packet processing, allowing efficient policy enforcement across multiple subnets without requiring separate rules.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
