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 policy rule references a service object "HTTP" which is pre-defined. What is the default port for the HTTP service object?
22
Why wrong: Port 22 is used for SSH.
443
Why wrong: Port 443 is used for HTTPS, not HTTP.
8080
Why wrong: Port 8080 is an alternate HTTP port but not the default.
80
Port 80 is the standard port for HTTP.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
80
The HTTP service object in Palo Alto Networks firewalls is pre-defined with TCP port 80, as specified in RFC 7230. This default mapping allows the firewall to identify and apply security policies to standard unencrypted web traffic. Option D is correct because port 80 is the IANA-assigned default port for HTTP.
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.
22
Why it's wrong here
Port 22 is used for SSH.
443
Why it's wrong here
Port 443 is used for HTTPS, not HTTP.
8080
Why it's wrong here
Port 8080 is an alternate HTTP port but not the default.
80
Why this is correct
Port 80 is the standard port for HTTP.

Common exam traps
Palo Alto Networks often tests the distinction between HTTP (port 80) and HTTPS (port 443), and the trap here is that candidates may confuse HTTP with HTTPS or assume a common alternate port like 8080 is the default.
Detailed technical explanation
Palo Alto Networks firewalls use service objects to simplify policy creation by mapping a service name (e.g., HTTP) to a specific protocol and port number. The pre-defined HTTP object uses TCP port 80, and when referenced in a security rule, the firewall automatically inspects traffic destined for that port. In real-world scenarios, administrators often create custom service objects for non-standard ports (e.g., TCP 8080) to avoid misconfiguring security policies.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
