Per latest update : https://aws.amazon.com/elasticloadbalancing/features/
Network Load Balancer now supports SSL offloading.
So the slide (Time Index 0:44) needs to be updated to indicate so.
Thanks Ananth, this is on my update list for both the course and the exam simulator.
Agree to Ananth. TLS support was introduced on Network Load Balancers in January 2019 (https://aws.amazon.com/blogs/aws/new-tls-termination-for-network-load-balancers/). So please update this.
