The correct interpretation is that the server blocks the PUT method for that specific URI. This occurs because the web server recognizes PUT as a valid HTTP method but has an explicit access control rule—such as an Apache `<LimitExcept>` directive or IIS request filtering—that denies it for that endpoint, meaning the request reached the server and was processed but was refused at the configuration level. On the CompTIA PenTest+ PT0-002 exam, this tests your ability to distinguish between a server rejecting a method entirely (which would yield a 501 Not Implemented) versus actively forbidding it for a particular resource, a common trap where testers mistakenly assume the method is unsupported. Remember the mnemonic: “405 = Forbidden Function, not Forgotten Function”—the server knows the verb but says “no” to that path.
PT0-002 Practice Question: Information Gathering and Vulnerability Scanning
This PT0-002 practice question tests your understanding of information gathering and vulnerability scanning. 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.
During a vulnerability scan of a web application, a tester receives an HTTP response with a '405 Method Not Allowed' error when trying to use a PUT request. What does this indicate about the web server's configuration?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The server blocks the PUT method for that specific URI.
A 405 Method Not Allowed error indicates that the server recognized the PUT method as valid but has explicitly disallowed it for the requested URI. This is a server-level access control configuration, often enforced via web server directives (e.g., Apache's `<LimitExcept>` or IIS's request filtering) or application-level routing rules. The tester's PUT request reached the server and was processed, but the server's configuration prevented it from being fulfilled for that specific endpoint.
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 server blocks the PUT method for that specific URI.
Why this is correct
405 precisely means the method is not allowed for the requested resource.
Related concept
Read the scenario before looking for a memorised answer.
✗
The PUT method is allowed but the resource does not exist.
Why it's wrong here
If the resource does not exist, the server would return 404 Not Found.
✗
The server does not support the PUT method.
Why it's wrong here
The server may support PUT on other resources; 405 is resource-specific.
✗
The request was malformed and rejected.
Why it's wrong here
A malformed request typically results in a 400 Bad Request.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse a 405 Method Not Allowed with a 501 Not Implemented, mistakenly thinking the server lacks PUT support entirely, when in fact the server supports PUT but has been configured to deny it for that specific URI.
Detailed technical explanation
How to think about this question
The 405 status code is defined in RFC 7231, Section 6.5.5, and requires the server to include an Allow header in the response listing the permitted methods for that URI. In practice, web servers like Apache use `<LimitExcept>` or `.htaccess` files to block specific HTTP methods on a per-directory or per-file basis, while application frameworks (e.g., Django, Flask) may enforce method restrictions at the route level. A tester can confirm this by checking the Allow header and testing other methods like OPTIONS to enumerate allowed verbs.

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 team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
