A read only news reporting site with a combined web and application tier and a database tier that receives
large and unpredictable traffic demands must be able to respond to these traffic fluctuations automatically.
What AWS services should be used meet these requirements?
A.
Stateless instances for the web and application tier synchronized using Elasticache Memcached in an
autoscaimg group monitored with CloudWatch. And RDSwith read replicas
B.
Stateful instances for me web and application tier in an autoscaling group monitored with CloudWatch and
RDS with read replicas
C.
Stateful instances for the web and application tier in an autoscaling group monitored with CloudWatch. And
multi-AZ RDS
D.
Stateless instances for the web and application tier synchronized using ElastiCache Memcached in an
autoscaling group monitored with CloudWatch and multi-AZ RDS

should be D

I will take it back, it should be A.
“A readonly reporting site” – so stateless and read-replicas can be used to scale. Multi-AZ will not provide the scaling requirements

Any kind of browsing where your actions on a webserver are read-only can be stateless.
Multi AZ provides redundancy, not scale.

A, readonly is stateless and read-replicas for scale
