Which term refers to announcements generated by services in response to access attempts?

• A. IP Address Spoofing
• B. Banner Guiding
• C. Anonymous Website Surfing Sites
• D. Firewall

Answer: (B)

When a service is contacted, it often sends back a banner—text that identifies the service and sometimes its version. These announcements are what the term in the question describes. They’re the informational messages produced in response to access attempts, and they’re a key piece of fingerprinting and reconnaissance because you can learn what service is running from the banner. The practice of obtaining these messages is commonly called banner grabbing, which fits the idea of services announcing themselves upon access attempts. The other options don’t fit: IP address spoofing is about forging the source address, anonymous website surfing sites relate to privacy, and a firewall is a protective device that blocks or filters traffic. So the term here captures those service-generated announcements.
