Here is an example. the 2 correct answers are independent solutions:
A technology company runs an industrial chain orchestration software on the AWS cloud. It consists of a web application tier that is currently deployed on a fixed fleet of Amazon EC2 instances. The database tier is deployed on Amazon RDS. The web and database tiers are deployed in the public and private subnet of the VPC respectively. The company wants to improve the service to make it more cost-effective, scalable, highly available and should require minimal human intervention.
Which of the following actions should the solutions architect implement to improve the availability and load balancing of this cloud architecture? (Select TWO.)
Create a Non-Alias Record in Route 53 with a Multivalue Answer Routing configuration and add all the IP addresses for your web servers. (CORRECT)
Set up a NAT instance in your VPC. Update your route table by creating a default route via the NAT instance with all subnets associated with it. Configure a DNS A Record in Route 53 pointing to the NAT instance’s public IP address.
Launch a load balancer in front of all the web servers then create a Non-Alias Record in Route 53 which maps to the DNS name of the load balancer.
Create a CloudFront distribution whose origin points to the private IP addresses of your web servers. Also set up a CNAME record in Route 53 mapped to your CloudFront distribution.
Place an Application Load Balancer in front of all the web servers. Create a new Alias Record in Route 53 which maps to the DNS name of the load balancer. (CORRECT)
