If you need to manuallyjoin an EC2 instance to your domain, you must launch the instance in the proper region and security group or subnet, then join the instance to the domain. To be able to connect remotely to these instances, you must have IP connectMty to the instances from the network you are connecting from.

Q6. You are in the process of creating a Route 53 DNS failover to direct traffic to two EC2 zones. Obviously, if one fails, you would like Route 53 to direct traffic to the other region. Each region has an ELB with some instances being distributed. What is the best way for you to configure the Route 53 health check?

A. Route 53 doesn't support ELB with an internal health check.You need to create your own Route 53 health check of the ELB

B. Route 53 natively supports ELB with an internal health check. Turn "Eva|uate target health" off and "Associate with Health Check" on and R53 will use the ELB's internal health check.

C. Route 53 doesn't support ELB with an internal health check. You need to associate your resource record set for the ELB with your own health check

D. Route 53 natively supports ELB with an internal health check. Turn "Eva|uate target health" on and "Associate with Health Check" off and R53 will use the ELB's internal health check.

Answer: D

Explanation:

With DNS Failover, Amazon Route 53 can help detect an outage of your website and redirect your end users to alternate locations where your application is operating properly. When you enable this feature, Route 53 uses health checks-regularly making Internet requests to your appIication’s endpoints from multiple locations around the world-to determine whether each endpoint of your application is up or down.

To enable DNS Failover for an ELB endpoint, create an Alias record pointing to the ELB and set the "EvaIuate Target HeaIth" parameter to true. Route 53 creates and manages the health checks for your ELB automatically. You do not need to create your own Route 53 health check of the ELB. You also do not need to associate your resource record set for the ELB with your own health check, because Route 53 automatically associates it with the health checks that Route 53 manages on your behalf. The ELB health check will also inherit the health of your backend instances behind that ELB.
