Cloud Technology & ServicesQuestion 62 of 100
Why should a highly available application be deployed across multiple Availability Zones?
a.To reduce the AWS bill to zero
b.So the application can continue running if one AZ experiences a failure
c.Because a single AZ cannot run any instances
d.To avoid using load balancers
Explanation
Spreading resources across multiple AZs means that if one zone fails, the application can continue serving traffic from the others. AZs are physically isolated, so this design improves availability and fault tolerance.
