Can I use RDS Multiple-AZ together with Read-Replica?

Question

RDS Multiple-AZ gives me the fail-over automatically when the master is down the standby instance will be promoted as mater, OFC they are synchronized,

With a few Read-Replica the over-all performance will be good.

So can I have them both at the same time, as shown below, for example:

Master --(across AZ)-- standby 
|
Read-Replica instance1
|
Read-Replica instance2

In the above case, I believe if Master is down, the standby will be as master, but question is whether the Read-Replica will break or not?

It depends what flavor of RDS you are using - If you are using RDS for MySQL, MariaDB or PostgreSQL, you can use RDS read replicas with Multi-AZ configurations.
