Final answer:
The command that provides information about all connections and listening ports, including the status and addresses, which is seen in the security consultant's output, is 'netstat -a'. so, option B is the correct answer.
Step-by-step explanation:
The output that the security consultant reviewed can be produced by the command netstat -a. This command displays all connections and listening ports for both TCP and UDP protocols, their status, and the corresponding addresses. The presence of 'Local Address' and 'Foreign Address' fields, combined with the status of the connections (Established, Waiting), are characteristic of the netstat command's output. It can be used by network administrators and security consultants to determine which connections are active on a machine, which can help in identifying if a database is being accessed or hosted on client machines.
The command that would have provided the given output is netstat -a.
The netstat command is used to display active network connections and listening ports. The -a option displays all connections and listening ports on the system.
By running netstat -a, the security consultant would be able to see the local and foreign addresses as well as the status of each connection
