AWS Web App: Site Availability and Cache Management MCQ

This is an architecture diagram of a web e-commerce storefront. The whole service is hosted in a single AWS region (us-east-2). Answer the question below.

Assume that the site can work without a cache. Is the application tolerant of a single availability zone failure?

 

Yes, but only if we switch to a network load balancer.

Yes, but only if we replace the frontend instances to C5d, which are network optimized and have tolerance for single zone failure.

Yes, but only if the database standby is configured properly and in a different zone than the master one.

No. This can only be achieved if we host in at least two AWS regions far away from each other.

None of these.
