The answer is to import the private key into Wireshark and enable TLS decryption. This technique works because Wireshark can use the server’s private key to decrypt the symmetric session keys exchanged during the TLS handshake, allowing it to read the encrypted HTTPS traffic as plaintext. On the CompTIA PenTest+ PT0-002 exam, this question tests your understanding of post-exploitation traffic analysis and the difference between passive decryption (using a captured private key) and active interception (like a proxy). A common trap is choosing Burp Suite, but Burp requires a CA certificate installed on the client, which is not possible when you only have the server’s private key. Remember: if you have the key, Wireshark does the work—no client-side changes needed. A helpful memory tip is “Key in, plaintext out: Wireshark’s TLS preference is the route.”
PT0-002 Tools and Code Analysis Practice Question
This PT0-002 practice question tests your understanding of tools and code analysis. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
During a penetration test, a tester needs to capture and analyze the traffic between a client and a server over an encrypted HTTPS connection. The tester has access to the server's private key. Which technique or tool should the tester employ?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Import the private key into Wireshark and enable TLS decryption
Using Wireshark with the server's private key allows decryption of TLS traffic by configuring the SSL/TLS protocol with the private key in the preferences. Burp Suite requires a CA certificate and proxy setup, but without client-side changes, it's less direct. TCPDump alone cannot decrypt. OpenSSL can be used to decrypt a captured session if the handshake is captured, but Wireshark is the standard tool for analysis.
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.
✗
Use Nmap's ssl-enum-ciphers script
Why it's wrong here
This script only enumerates supported ciphers, not captures traffic.
✗
Use Burp Suite with a proxy
Why it's wrong here
Burp Suite requires client-side proxy configuration and may not work if the client is not configured.
✓
Import the private key into Wireshark and enable TLS decryption
Why this is correct
Wireshark can use the private key to decrypt TLS traffic when configured in the TLS protocol preferences.

✗
Capture packets with TCPDump and analyze with OpenSSL
Why it's wrong here
OpenSSL can decrypt if you have the key and the session, but it's less integrated than Wireshark.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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
How to think about this question
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.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
