A Company Is Currently Running a Website on Site

question 5

Multiple Choice

A company is currently running a website on site. However, because of a business requirement to reduce current RTO from 12 hours to one hour, and the RPO from one day to eight hours, the company is considering operating in a hybrid environment. The website uses mostly static files and a small relational database. Which of the following should the cloud architect implement to achieve the objective at the LOWEST cost possible?

• A) Implement a load-balanced environment in the cloud that is equivalent to the current on-premises setup and use DNS to shift the load from on premises to cloud.
• B) Implement backups to cloud storage and infrastructure as code to provision the environment automatically when the on-premises site is down. Restore the data from the backups.
• C) Implement a website replica in the cloud with auto-scaling using the smallest possible footprint. Use DNS to shift the load from on premises to the cloud.
• D) Implement a CDN that caches all requests with a higher TTL and deploy the IaaS instances manually in case of disaster. Upload the backup on demand to the cloud to restore on the new instances.
