DNS is LEVEL4 - N/W Layer
HTTPS/SSL is Layer 7(6) - Above 4
So, DNS is merely Server resolving , it does not know anything at SSL TLS HTTPS level
So, We direct DNS to Load Balancer
Load Balancer has a listener which redirects traffic internally
Load Balancer is at TCP Port 80
TCP Port 80 redirects to Port 443 at Load balancer Level
here at LB SSL offloading Happens
PFX File, CER File is issued to "DNS Name " and "Subject Alternative Names" to FQDN of Host Backends
DNS has Record Set Types:
