PT0-003 Question #251: Real Exam Question with Answer & Explanation

The correct answer is A: nmap --script ssl-enum-ciphers. Explanation nmap --script ssl-enum-ciphers is correct because it uses Nmap's scripting engine to actively probe a target web service and enumerate all supported SSL/TLS versions and cipher suites, giving the tester a complete picture of which potentially insecure protocols (e.g.,

Question

A penetration tester wants to identify all the TLS versions used in a web service in order to determine potentially insecure versions. Which of the following commands should the tester use?

Options

  • Anmap --script ssl-enum-ciphers
  • Bcurl --tls-max 3
  • Cwget --server-response
  • Dopenssl version

Explanation

Explanation

nmap --script ssl-enum-ciphers is correct because it uses Nmap's scripting engine to actively probe a target web service and enumerate all supported SSL/TLS versions and cipher suites, giving the tester a complete picture of which potentially insecure protocols (e.g., SSLv3, TLS 1.0) are enabled. Option B (curl --tls-max 3) simply sets a maximum TLS version for a single connection attempt rather than enumerating all supported versions. Option C (wget --server-response) only retrieves HTTP response headers and provides no SSL/TLS version enumeration. Option D (openssl version) merely displays the version of the locally installed OpenSSL library - it tells you nothing about what a remote server supports.

Memory Tip: Think "nmap scripts = reconnaissance" - whenever an exam question asks about enumerating or discovering service configurations on a remote target, Nmap's --script option (NSE) is almost always the right tool. The keyword "enum" in ssl-enum-ciphers is a direct giveaway that this script is built for enumeration.
