Question

Karen identifies TCP ports 8080 and 8443 open on a remote system during a port scan. What tool is her best option to manually validate the services running on these ports?

a.

SSH

b.

SFTP

c.

Telnet

d.

A web browser

Answer: (d).A web browser Explanation:Karen knows that many system administrators move services from their common service ports to alternate ports and that 8080 and 8443 are likely alternate HTTP (TCP 80) and HTTPS (TCP 443) server ports, and she will use a web browser to connect to those ports to check them. She could use Telnet for this testing, but it requires significantly more manual work to gain the same result, making it a poor second choice unless Karen doesn’t have another option.
