ServiceNow CIS-Discovery free question 6 / 10 · Domain 2: Discovery Configuration
In credential-less Application Discovery, which does Nmap return? (Choose two.)
- Service name
- Service product
- Disk usage
- Host uptime
Show the answer and explanation
Answer: A, B
Why this is correct
The example Nmap application/version detection scan returns the port state, the service name, the service product, and extra service information. The service product is mapped to a CI class; the service name is needed for a match only in some cases.
Why the other options are wrong
"Disk usage" … Nmap detects the application listening on a port at an IP address. Disk usage would need a login to the host, which this discovery does not have.
"Host uptime" … Nmap detects the application listening on a port at an IP address. How long the host has been up is not part of that detection.
Key point
The less Nmap returns, the more likely the CI lands in the base table. Credential-less results are coarser than credential-based ones.
