A fleet of Amazon Elastic Compute Cloud (Amazon EC2) instances launch in an Auto Scaling group.
The instances run an application that uses a custom protocol on TCP port 42000. Connections from
client systems on the internet must balance across the instances. Which load balancing solution
ensures the highest availability?
- Round-robin DNS
- Application Load Balancer
- Network Load Balancer
- Instance-based load balancer - ANSWER-Network Load Balancer
Users in location A connect to an application in Region A. Users in location B connect to the same
application in Region B. If the application in Region A becomes unhealthy, clients in location A must
be redirected to the application in Region B. Which solution can meet this requirement?
- Use an Application Load Balancer with Amazon CloudWatch alarms.
- Use geolocation routing with failover records in Amazon Route 53.

ANSWER-Use geolocation routing with failover records in Amazon Route 53.
A company must build a highly available website that uses server-side scripts to serve dynamic
HTML. Which solution provides the highest availability for the least cost and complexity?
- An Auto Scaling group launches Amazon EC2 instances, which are served by an Application Load
Balancer. DNS name resolution points to the load balancer.
- Amazon S3 hosts the website. DNS name resolution points to the S3 bucket.

disaster recovery (DR). - ANSWER-An Auto Scaling group launches Amazon EC2 instances, which
are served by an Application Load Balancer. DNS name resolution points to the load balancer.
