Question

What option below will increase the fault tolerance of your application in AWS?

a) Deploy resources to multiple subnets

b) Deploying resources across multiple edge locations

c) Deploy resources across multiple availability zones

d) Deploy resources to multiple AWS accounts

Answer 1

c) Deploy resources across multiple availability zones

By deploying resources across multiple availability zones, you are designing with a failure in mind. So if one AZ goes down, the other AZ would still be up and running making your application more fault tolerant.
