Chapter 13, Implementing Azure Load Balancer

1. 1 and 4—You should deploy a second Load Balancer using the Basic tier and use this one to route traffic to the new availability set or delete the old Load Balancer and create a new one using the Standard tier. Only the Standard tier is allowed to route traffic to different availability sets.
2. 2—You should configure an inbound network address translation (NAT) rule that maps TCP port 3389 to VM1. Inbound NAT rules are designed to map a port to an internal IP address of a VM.
3. 1—You should create a new health probe that uses HTTP as the protocol and include the path to the NewVersion.html file. Health probes are designed to test whether a port or file is accessible.
