The answer is that the Nmap SMB script requires administrative credentials to enumerate shares. This is because scripts like smb-enum-shares.nse attempt anonymous or guest logins by default, but modern Windows servers disable anonymous SMB access as a security hardening measure. Without valid credentials, the script connects but receives no share list, even though shares exist. On the CompTIA PenTest+ PT0-002 exam, this tests your understanding of SMB authentication requirements versus tool behavior—a common trap is assuming a script that runs without errors has succeeded. Remember that Nmap’s SMB enumeration is not a magic wand; it respects the target’s access controls. For the exam, think: “No shares returned? Check your creds, not your switches.” A useful memory tip is SMB-CAN: Shares Must Be Credentialed, Always Negotiate.
PT0-002 Tools and Code Analysis Practice Question
This PT0-002 practice question tests your understanding of tools and code analysis. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 penetration tester is using an Nmap NSE script to enumerate SMB shares on a target Windows server. The script runs without errors but returns no shares, even though the server has shares configured. Which is the MOST likely cause?

Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The script requires administrative credentials
The Nmap SMB enumeration scripts (e.g., smb-enum-shares.nse) by default attempt to connect as a guest or anonymous user. On modern Windows servers, especially those with default security configurations, anonymous access to SMB shares is disabled. The script requires valid administrative credentials to list all shares, as the SMB protocol restricts share enumeration to authenticated users with appropriate privileges.
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.
✓
The script requires administrative credentials
Why this is correct
SMB share enumeration typically requires valid credentials, without which the script cannot enumerate shares.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The target is running Windows 10 with SMB signing enabled
Why it's wrong here
SMB signing does not prevent script execution; it only adds integrity checks.
✗
The script is not being run with the correct arguments
Why it's wrong here
Incorrect arguments would likely produce an error message or no output, but the script ran without errors.
✗
The target is blocking ICMP traffic
Why it's wrong here
ICMP blocking does not affect SMB scanning over TCP port 445.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume Nmap scripts run with full default access, overlooking that SMB enumeration on modern Windows requires explicit authentication, not just a null session.
Trap categories for this question
Command / output trap
Incorrect arguments would likely produce an error message or no output, but the script ran without errors.
Detailed technical explanation
How to think about this question
Under the hood, the SMB protocol uses the NetShareEnum API (via MSRPC over SMB) to list shares. This API requires the caller to have the 'SeNetworkLogonRight' and appropriate share-level permissions. Without credentials, the script falls back to a null session, which Windows Server (since Windows 2000 and later) disables by default. In real-world assessments, testers must supply credentials using the --script-args 'smbuser=...','smbpass=...' or use a credential file to enumerate shares successfully.

TExam Day Tips
→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 security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
