The correct choice is an IP Netmask object using the public IP 203.0.113.10/32. This is because the firewall evaluates the destination IP address in the packet header of inbound traffic, which will be the server’s public address, not its private NAT address. An IP Netmask object with a /32 prefix precisely matches a single host, ensuring the security policy applies only to that exact public IP. On the PCNSA exam, this question tests your understanding of how Palo Alto Networks firewalls process traffic flows and the distinction between address object types like IP Netmask, IP Range, and FQDN. A common trap is choosing the private IP or an IP Range object, but remember: for internet-accessible servers, the destination in the security rule must match the packet’s visible destination IP. A helpful memory tip is “public packet, public object”—if the packet arrives with a public destination, use an IP Netmask object with that public address.
PCNSA Managing Objects Practice Question
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.
A security administrator is configuring an address object for a web server accessible from the internet. The server has a public IP of 203.0.113.10/32 and a private IP of 10.0.1.10/32. The administrator needs to create a security policy that allows inbound HTTPS traffic to the server. Which address object type should be used for the destination?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
IP Netmask (e.g., 203.0.113.10/32)
The correct answer is D because the security policy destination must match the IP address that the firewall sees in the packet header. For inbound traffic from the internet, the destination IP is the public IP 203.0.113.10/32, so an IP Netmask object with that exact address is the appropriate type. Using a /32 netmask ensures a single host match, which is precise and efficient for firewall rule evaluation.
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.
✗
FQDN (e.g., webserver.example.com)
Why it's wrong here
FQDN is dynamic and not recommended for inbound policies where the destination IP must be static.
✗
IP Range (e.g., 10.0.1.10-10.0.1.10)
Why it's wrong here
IP Range can define a single IP, but IP Netmask is more standard.
✗
IP Wildcard Mask (e.g., 203.0.113.0/0.0.0.255)
Why it's wrong here
Wildcard masks are used for complex address matching but are not the best practice for a single host.
✓
IP Netmask (e.g., 203.0.113.10/32)
Why this is correct
IP Netmask /32 is the correct and most efficient way to represent a single host.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the private IP (used internally) with the public IP (used for inbound internet traffic), leading them to select an object type that references the private address, such as IP Range or FQDN, instead of the correct public IP Netmask.
Detailed technical explanation
How to think about this question
In Palo Alto Networks firewalls, address objects are used in security policy rules to match source and destination IPs. The IP Netmask type uses CIDR notation (e.g., /32) to define a single host, which is the most precise method for a static public IP. Under the hood, the firewall performs a longest-prefix-match lookup against the packet's destination IP; a /32 entry ensures an exact match without ambiguity. In a real-world scenario, if the web server had multiple public IPs or was behind a NAT, you might use a different object type, but here the public IP is fixed and directly reachable.

Real-world example
How this comes up in practice
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.

Variation 1. An administrator needs to block traffic from a specific internal IP address to the internet. Which object type should be used in the security policy source field?
easy
✓ A.Address object
B.Tag
C.Address group
D.Region
Why A: To block traffic from a specific internal IP address to the internet, you must identify that source IP in the security policy rule. An Address Object is the correct object type because it represents a single IP address or subnet and can be directly placed in the source field of a security policy rule to match traffic from that host. Tags, Address Groups, and Regions are not designed to represent a single IP address for source matching in this context.
