Quick Answer
The answer is Best Practice, Alert, and Strict. These three are the default security profile groups in PAN-OS, predefined by Palo Alto Networks to provide out-of-the-box protection against common threats. Each group bundles a set of security profiles—such as antivirus, anti-spyware, and vulnerability protection—with specific action settings; for example, the Strict group applies more aggressive blocking than Alert, which only logs threats. On the PCNSA exam, this question tests your familiarity with the default groups versus user-created ones, often using traps like “Server” or “Custom” to mislead candidates who confuse custom configurations with defaults. A common memory tip is to remember the three defaults as “ABS”—Alert, Best Practice, and Strict—since they escalate in severity from logging to blocking, while “Server” and “Custom” are red herrings.
This PCNSA practice question tests your understanding of core concepts. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which THREE are default security profile groups in PAN-OS? (Choose three.)
Strict
The 'Strict' group has more restrictive settings.
Server
Why wrong: There is no default 'Server' profile group.
Alert
The 'Alert' group logs all matches without blocking.
Custom
Why wrong: 'Custom' is not a default group; it is created by administrators.
Best Practice
This is a default security profile group that includes recommended settings.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Strict
Options A, C, D are correct. These are predefined profile groups. Option B is wrong because 'Server' is not a default group; there is 'Strict' but not 'Server'. Option E is wrong because 'Custom' is not a default group; custom groups are user-created.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
