The answer is the PA-220. This platform is the correct choice for a branch office firewall deployment with 50 users because it is a purpose-built, entry-level next-generation firewall designed specifically for small to medium-sized businesses and remote offices, offering up to 100 Mbps of threat prevention throughput while still supporting core NGFW features like App-ID, User-ID, and SSL decryption. On the Palo Alto Networks Certified Network Security Administrator PCNSA exam, this scenario tests your ability to match hardware models to user counts and throughput requirements, often appearing as a straightforward sizing question that can be confused with the higher-capacity PA-800 series. A common trap is selecting the PA-220R (ruggedized) for a standard office, but remember the standard PA-220 is the baseline for up to 50 users. Memory tip: think "220 for 20 to 50" — the PA-220 comfortably handles a small branch office without overspending.
PCNSA Palo Alto Networks Platforms and Architecture Practice Question
This PCNSA practice question tests your understanding of palo alto networks platforms and architecture. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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 company needs to deploy a firewall for a branch office with 50 users. Which Palo Alto Networks platform is most appropriate for this requirement?
Why wrong: PA-3250 is a mid-range model for larger environments, not for a small branch with 50 users.
B
PA-220
PA-220 is the entry-level hardware platform suitable for small branch offices with up to 50 users.
C
VM-Series
Why wrong: VM-Series is virtual and could be used, but physical hardware is typically preferred for branch offices and the PA-220 is more cost-effective.
D
PA-5280
Why wrong: PA-5280 is a high-end data center firewall, overkill for a 50-user branch.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
PA-220
The PA-220 is the most appropriate platform for a branch office with 50 users because it is a low-end, entry-level next-generation firewall designed for small to medium-sized businesses and remote/branch offices. It supports up to 100 Mbps of threat prevention throughput and includes all core NGFW features (App-ID, User-ID, SSL decryption) at a cost-effective price point, making it ideal for this user count.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose the PA-3250 (Option A) because they assume a 'branch office' needs a mid-range model for reliability, but the PA-220 is specifically designed for small branches and is the correct answer based on user count and throughput requirements.
Detailed technical explanation
How to think about this question
The PA-220 uses a single-core ARM-based processor (Marvell ARMADA XP) and runs PAN-OS with a reduced feature set compared to higher-end models (e.g., no hardware acceleration for IPsecVPN, limited log storage). In real-world scenarios, a 50-user branch might also need to consider future growth or bandwidth requirements; if the branch expects to exceed 100 Mbps of threat prevention throughput, the PA-220 would need to be upgraded to a PA-440 or PA-410, which offer higher throughput and newer hardware. The PA-220's maximum concurrent sessions (50,000) are sufficient for 50 users but could become a bottleneck if users run heavy P2P or streaming applications.

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 practitioner preparing for the PCNSA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
