Question 62
A web company is looking to implement an external payment service into their highly available application deployed in a VPC Their application EC2 instances are behind a public facing ELB. Auto scaling is used to add additional instances as traffic increases under normal load the application runs 2 instances in the AutoScaling group but at peak it can scale 3x in size. The application instances need to communicate with the payment service over the Internet which requires whitelisting of all public IP addresses used to communicate with it. A maximum of 4 whitelisting IP addresses are allowed at a time and can be added through anAPI. How should they architect their solution?
Question 63

Question 66
You are running a news website in the eu-west-1 region that updates every 15 minutes. The website has a world-wide audience. It uses an Auto Scaling group behind an Elastic Load Balancer and an Amazon RDS database. Static content resides on Amazon S3, and is distributed through Amazon CloudFront. Your AutoScaling group is set to trigger a scale up event at 60% CPU utilization. You use an Amazon RDS extra large DB instance with 10. 000 Provisioned IOPS, its CPU utilization is around 80%, while freeable memory is in the 2 GB range. Web analytics reports show that the average load time of your web pages is around 1. 5 to 2 seconds, but your SEO consultant wants to bring down the average load time to under 0. 5 seconds. How would you improve page load times for your users? (Choose three.)

After a file has been uploaded, it is copied to Amazon Simple Storage Service (S3). Amazon EC2 instances use an AWS Identity and Access Management (IAM) role that allows Amazon S3 uploads. Over the last six months, your user base and scale have increased significantly, forcing you to increase the Auto Scaling group's Max parameter a few times. Your CFO is concerned about rising costs and has asked you to adjust the architecture where needed to better optimize costs.
