This PCNSE practice question tests your understanding of securing traffic and app-id. 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.
A firewall shows session logs with application 'incomplete' for many SSL connections. Which action should be taken to improve App-ID accuracy?
Disable application identification for SSL traffic.
Why wrong: Disabling would not help.
Enable HTTP/2 protocol decoding.
Why wrong: HTTP/2 is a protocol, but without decryption, still encrypted.
Enable SSL decryption for the traffic.
Decryption reveals the underlying application.
Allow sessions with application 'incomplete' in policy.
Why wrong: Allowing does not improve identification.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Enable SSL decryption for the traffic.
Option A is correct because SSL decryption allows the firewall to inspect encrypted content, improving application identification. Option B is wrong because allowing incomplete sessions does not improve accuracy. Option C is wrong because disabling security policies is not necessary. Option D is wrong because enabling HTTP/2 is not directly relevant.
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.
Disable application identification for SSL traffic.
Why it's wrong here
Disabling would not help.
Enable HTTP/2 protocol decoding.
Why it's wrong here
HTTP/2 is a protocol, but without decryption, still encrypted.
Enable SSL decryption for the traffic.
Why this is correct
Decryption reveals the underlying application.
Related concept

Allow sessions with application 'incomplete' in policy.
Why it's wrong here
Allowing does not improve identification.
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 PCNSE 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.
