Ola B.Jun 26, 2026D is your answer. Network scanners rely on signature databases to detect vulnerabilities, and if you bought it six months ago and never updated it, it simply does not know about any vulnerabilities discovered in the last month, which is exactly the window attackers exploited. Spin up a lab VM, install an old unpatched scanner, run it against a known recent CVE, and you will see it miss the finding completely, that hands-on test will cement this concept better than any flashcard.
Viktor S.Jun 28, 2026The lab test idea is solid, but make sure you also show the scanner catching something it does know about in the same run, because without that control you cannot tell if it missed the CVE due to a stale database or due to a config issue like insufficient privileges or excluded ports.
Viktor S.Jun 26, 2026If the scanner worked fine for five months, what changed?
Dervla O.Jun 19, 2026D is the right call here. A scanner is only as good as its vulnerability definitions, and if you bought it six months ago and never pushed an update, it cannot detect anything discovered after that point, which is exactly the window attackers exploit.
