Your company is planning to set up applications over the internet with the following aspects.
· 2 Applications, each with its own domain name
· Each application will have EC2 Instances as Web servers
You need to ensure High Availability for the servers and also configure Route53. How would you achieve this? Choose 2 answers from the options given below.
 

Answer options:

A.Configure 2 private hosted zones in Route 53.
B.Configure 2 public hosted zones in Route 53.
C.Create a public Elastic Load Balancer.
D.Create a private Elastic Load Balancer.

Answer – B and C
Since 2 domains are required, and these are Web servers that most probably will need to be exposed to the Internet, you need to define 2 separate public hosted zones and an ELB.Options A and D are incorrect since private zones and ELBs will not allow access to the resources from the Internet.
