ServiceNow Certified Implementation Specialist – Service Mapping — Question 28

Which one of the following Linux commands can be used by a non root user to return the process ID listening on port 8080?

Answer options

• A. sudo netstat -an -p TCP | grep :8080
• B. sudo netstat -anp | grep :8080
• C. netstat -anp | grep :8080
• D. netstat -an -pid * | grep :8080

Correct answer: B

Explanation

The correct answer is B because it allows a non-root user to view the process ID associated with port 8080 using 'sudo' to elevate privileges temporarily. Option A is incorrect as it specifies 'TCP' unnecessarily, and options C and D do not use 'sudo', which may prevent a non-root user from accessing the necessary information.
