Which resource provides a database of default passwords and credentials?

• A. NCollector Studio
• B. ID Serve
• C. cirt.net
• D. robots.txt

Answer: (C)

Focusing on a resource that specifically collects and shares default login information, this is a repository tailored for quickly checking whether devices or systems are still using factory credentials. cirt.net is a well-known, community-maintained database of default usernames and passwords for a wide range of devices and platforms, making it a go-to reference for penetration testers to verify if defaults have been left in place.

Robots.txt is a standard file that tells web crawlers which parts of a site to avoid; it has nothing to do with credentials. NCollector Studio is a data collection and assessment tool rather than a credential database, and ID Serve isn’t recognized as a repository for default credentials.
