- A
Use SQLmap with --tamper scripts to bypass the WAF
Why wrong: While tampering might work, it is not the best next step because you have immediate access to the file server via SMB guest.
- B
Scan the file server for vulnerabilities using Nmap NSE scripts
The SMB guest access provides a direct opportunity to enumerate the file server and potentially find vulnerabilities (e.g., EternalBlue) that could lead to system compromise.
- C
Attempt to brute-force the MySQL root password on the database server
Why wrong: You do not have network connectivity to the database server, so brute-forcing is not possible from your current position.
- D
Conduct a phishing campaign against employees to gain elevated credentials
Why wrong: Phishing is an option, but it does not leverage the guest SMB access you already have and is less direct than exploiting the file server.
Quick Answer
The answer is to scan the file server for vulnerabilities using Nmap NSE scripts. This is the correct next step because, after the WAF blocks your SQL injection attempts, you must pivot to the most accessible and promising target—the SMB file server with guest access enabled. Scanning it with Nmap’s scripting engine can reveal SMB-specific weaknesses, such as EternalBlue or misconfigurations, which could provide a foothold for lateral movement toward the isolated database server. On the CompTIA PenTest+ PT0-002 exam, this scenario tests your ability to prioritize actions based on current access and network segmentation; a common trap is wasting time trying to bypass the WAF immediately or brute-forcing a database you cannot reach. The key lesson is that penetration testing next step after WAF blocking SQL injection is to exploit the path of least resistance. Memory tip: “When the WAF slams the door, scan the SMB floor.”
PT0-002 Practice Question: Information Gathering and Vulnerability Scanning
This PT0-002 practice question tests your understanding of information gathering and vulnerability scanning. 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.
You are a penetration tester hired to assess the security of a mid-sized company. The company's internal network consists of a web server running Apache 2.4.29 on Ubuntu 18.04, a database server with MySQL 5.7 on CentOS 7, and a file server running Samba 4.8 on a separate Linux distribution. You are given a standard domain user account with limited privileges. After initial reconnaissance, you discover that the web server has a SQL injection vulnerability in its login form. However, when you attempt to exploit it with SQLmap, the web application firewall (WAF) blocks all your payloads. You also notice that the file server is accessible via SMB with guest access enabled, allowing you to list shares without authentication. The database server is isolated on a separate VLAN and is not directly accessible from your workstation. Which of the following actions should you take NEXT to further your assessment?

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Scan the file server for vulnerabilities using Nmap NSE scripts
With guest access to the SMB file server, you can probe it for vulnerabilities using Nmap's scripting engine (NSE). This could reveal additional weaknesses that might provide a foothold or lateral movement paths. Attempting to bypass the WAF immediately (option A) is possible but may be time-consuming and less likely to succeed without more information. Brute-forcing the MySQL root password (option C) is not feasible because you cannot reach the database server directly. Phishing (option D) is an option but it does not leverage the current access and may not be the most efficient next step.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

- ✗
Use SQLmap with --tamper scripts to bypass the WAF
Why it's wrong here
While tampering might work, it is not the best next step because you have immediate access to the file server via SMB guest.
- ✓
Scan the file server for vulnerabilities using Nmap NSE scripts
Why this is correct
The SMB guest access provides a direct opportunity to enumerate the file server and potentially find vulnerabilities (e.g., EternalBlue) that could lead to system compromise.

Authentication checks who the user is.
- ✗
Attempt to brute-force the MySQL root password on the database server
Why it's wrong here
You do not have network connectivity to the database server, so brute-forcing is not possible from your current position.
- ✗
Conduct a phishing campaign against employees to gain elevated credentials
Why it's wrong here
Phishing is an option, but it does not leverage the guest SMB access you already have and is less direct than exploiting the file server.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
An employee at a financial services firm receives an email that appears to come from the IT helpdesk, asking them to reset their password via a link. The link leads to a convincing fake portal that harvests credentials. Security teams use phishing simulations and security-awareness training to reduce this attack vector. Questions like this test whether you can identify social engineering techniques and appropriate controls.
