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.
Which TWO types of address objects can be used in a security policy? (Choose two.)
Application
Why wrong: Application is a separate object type for applications.
Tag
Why wrong: Tag is used for grouping, not as an address type.
IP Netmask
IP Netmask is a standard address object type.
IP Range
IP Range is another standard address object type.
Service
Why wrong: Service is a separate object type for ports/protocols.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
IP Netmask
IP Netmask and IP Range are both types of address objects that define specific IP addresses or groups of IP addresses. Security policies in Palo Alto Networks firewalls use these address objects to match source and destination IP addresses in traffic, enabling granular control over which hosts or networks are allowed or denied.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Application
Why it's wrong here
Application is a separate object type for applications.
Tag
Why it's wrong here
Tag is used for grouping, not as an address type.
IP Netmask
Why this is correct
IP Netmask is a standard address object type.

Common exam traps
Palo Alto Networks often tests the distinction between address objects and other policy elements like services or applications, so the trap here is that candidates mistakenly think Application or Service can serve as address objects because they are also used in security rules, but they occupy different match fields.
Detailed technical explanation
Address objects in Palo Alto Networks include IP Netmask (e.g., 192.168.1.0/24) and IP Range (e.g., 192.168.1.10-192.168.1.20), which are stored in the firewall's object database and referenced by security rules. The firewall matches traffic by comparing the packet's source and destination IP against these objects using longest-prefix matching for netmasks and range inclusion for IP ranges. In a real-world scenario, an organization might use IP Range objects to define a DHCP-assigned client pool that is not contiguous on a subnet boundary, where a netmask would be too broad.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
