AWS Solutions Architect Questions and Answers Part-10
1.Your company currently has a 2-tier web application running in an on-premises data center. You have experienced several infrastructure failures in the past two months resulting in significant financial losses. Your CIO is strongly agreeing to move the application to AWS. While working on achieving buy-in from the other company executives, he asks you to develop a disaster recovery plan to help improve Business continuity in the short term. He specifies a target Recovery Time Objective (RTO) of 4 hours and a Recovery Point Objective (RPO) of 1 hour or less. He also asks you to implement the solution within 2 weeks. Your database is 200GB in size and you have a 20Mbps Internet connection. How would you do this while minimizing costs?         A.Create an EBS backed private AMI which includes a fresh install or your            application. Setup a script in your data center to backup the local database         every 1 hour and to encrypt and copy the resulting file to an S3 bucket using        multi-part upload.     b.Install your application on a compute-optimized EC2 instance capable of            supporting the application’s average load synchronously replicate transactions       from your on-premises database to a database instance in AWS across a            secure Direct Connect connection.     C.Deploy your application on EC2 instances within an Auto Scaling group across        multiple availability zones asynchronously replicate transactions from your on-       premises database to a database instance in AWS across a secure VPN             connection.      D.Create an EBS backed private AMI that includes a fresh install of your            application. Develop a Cloud Formation template which includes your AMI and        the required EC2. Auto-Scaling and ELB resources to support deploying the          application across Multiple-Ability Zones. Asynchronously replicate transactions      from your on-premises database to a database instance in AWS across a secure      VPN connection.  D.Create an EBS backed private AMI which includes a fresh install of your application.
