The answer is to use a URL Filtering profile to block the Social Networking category. This is correct because Palo Alto Networks firewalls categorize millions of URLs into predefined groups, such as Social Networking, and a URL Filtering profile allows you to set an action—like block—for that entire category. When this profile is applied to a security policy rule governing internet access, the firewall can identify and block HTTP/HTTPS traffic to social media sites based solely on their URL category, without needing to decrypt or inspect the content. On the PCNSA exam, this tests your understanding of how to enforce acceptable use policies using category-based URL filtering, a core concept for controlling web traffic. A common trap is confusing URL Filtering with SSL Decryption or Application-ID; remember that URL Filtering blocks by web category, not by application. Memory tip: think “URL = web address category, App-ID = application behavior.”
PCNSA Palo Alto Networks Platforms and Architecture Practice Question
This PCNSA practice question tests your understanding of palo alto networks platforms and architecture. 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 provide internet access to employees while blocking access to social media sites. Which feature should be used to identify and block social media traffic?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
URL Filtering profile to block the Social Networking category.
A URL Filtering profile allows the administrator to block access to specific categories of websites, such as Social Networking. By applying this profile to a security policy rule that governs internet access, the firewall can identify and block HTTP/HTTPS traffic to social media sites based on their URL category, without needing to decrypt or inspect the content.
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.
✓
URL Filtering profile to block the Social Networking category.
Why this is correct
URL Filtering can block entire categories of websites.
Related concept
Read the scenario before looking for a memorised answer.
✗
SSL Decryption policy to decrypt traffic to social media.
Why it's wrong here
Decryption does not block; it only allows inspection.
✗
QoS policy to limit bandwidth to social media sites.
File blocking profile to block executable files from social media.
Why it's wrong here
This blocks files, not access to the sites.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse SSL Decryption (which enables visibility into encrypted traffic) with the actual blocking mechanism, not realizing that URL Filtering profiles are the correct tool for category-based blocking without requiring decryption.
Detailed technical explanation
How to think about this question
Palo Alto Networks URL Filtering uses a cloud-based database (PAN-DB) to categorize URLs into over 80 categories, including Social Networking. The firewall matches the URL against this category in real time and can block, allow, or alert based on the profile settings. In a real-world scenario, an administrator might also combine URL Filtering with User-ID to block social media only for certain user groups, while allowing it for others.

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.
