Last task of lab 7.2, section 28 hint?

Hello everybody! In last lab task 7.2.28 there is a meaning "Deploy the httpd server again and test changing traffic from thirdpage over to a new httpd sever using only ingress rule edits." I interpret that as to come up with alternate way to point to a backend. i could not find a much different way except maybe using ExternalName service feature? is that whats hinted?
