Quick Answer
The answer is to create an address group and a service group. This is the most efficient method because an address group allows you to logically bundle multiple server IP addresses into a single object, while a service group groups the common port 443, enabling one security policy rule to match all the servers and the specific service simultaneously. On the PCNSA exam, this scenario tests your understanding of object-based policy design to reduce rule count and administrative overhead, often appearing as a trap where candidates mistakenly create separate rules for each server. The key insight is that grouping multiple servers with the same port leverages group objects for scalability, avoiding a cluttered rulebase. Memory tip: think “one rule to rule them all” — combine address and service groups to keep your policy clean and efficient.
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 wants to group multiple servers with different IP addresses that all use the same port 443. What is the most efficient way to create a security policy rule for this traffic?
Use a single address object with a subnet
Why wrong: Using a subnet may include unintended IPs.
Create separate rules for each server
Why wrong: Inefficient and hard to maintain.
Use a dynamic address group with tags
Why wrong: Dynamic groups add complexity; static groups are simpler here.
Create an address group and a service group
This reduces administrative effort and groups related objects.

Correct answer & explanation
Create an address group and a service group
Option D is correct because creating an address group to contain the multiple server IP addresses and a service group for port 443 allows a single security policy rule to match all the servers and the specific service. This is the most efficient method as it reduces rule count and administrative overhead, leveraging group objects for scalability and ease of management.
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.
Use a single address object with a subnet
Why it's wrong here
Using a subnet may include unintended IPs.
Create separate rules for each server
Why it's wrong here
Inefficient and hard to maintain.
Use a dynamic address group with tags
Why it's wrong here
Dynamic groups add complexity; static groups are simpler here.
Create an address group and a service group
Why this is correct
This reduces administrative effort and groups related objects.

Common exam traps
The trap here is that candidates may confuse dynamic address groups (which rely on tags and external data) with static address groups, or assume that a single subnet object can cover non-contiguous IPs, leading them to choose option A or C.
Detailed technical explanation
In Palo Alto Networks firewalls, address groups and service groups are logical containers that simplify policy creation. Address groups can include multiple address objects (IP addresses, subnets, or FQDNs), while service groups can include multiple service objects (protocols and ports). Under the hood, the firewall evaluates the group membership at the time of policy matching, allowing a single rule to efficiently handle traffic to multiple destinations on the same port. In a real-world scenario, an administrator managing a web server farm with distinct IPs (e.g., 10.1.1.10, 10.1.1.20, 10.1.1.30) would use an address group and a service group for HTTPS (TCP/443) to avoid creating three 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.
