An education company is running a web application used by college students around the world. The application runs in an Amazon Elastic Container Service (Amazon ECS) cluster in an Auto Scaling group behind an Application Load Balancer (ALB). A system administrator detected a weekly spike in the number of failed logic attempts. Which overwhelm the application’s authentication service. All the failed login attempts originate from about 500 different IP addresses that change each week. A solutions architect must prevent the failed login attempts from overwhelming the authentication service.
Which solution meets these requirements with the MOST operational efficiency?
A company has used infrastructure as code (IaC) to provision a set of two Amazon EC2 instances. The instances have remained the same for several years.
The company ' s business has grown rapidly in the past few months. In response the company ' s operations team has implemented an Auto Scaling group to manage the sudden increases in traffic. Company policy requires a monthly installation of security updates on all operating systems that are running.
The most recent security update required a reboot. As a result, the Auto Scaling group terminated the instances and replaced them with new, unpatched instances.
Which combination of steps should a solutions architect recommend to avoid a recurrence of this issue? (Choose two.)
A company is creating a REST API to share information with six of its partners based in the United States. The company has created an Amazon API Gateway Regional endpoint. Each of the six partners will access the API once per day to post daily sales figures.
After initial deployment, the company observes 1.000 requests per second originating from 500 different IP addresses around the world. The company believes this traffic is originating from a botnet and wants to secure its API while minimizing cost.
Which approach should the company take to secure its API?
A company needs a hybrid DNS architecture. The architecture must include the company’s on-premises network and a VPC. An AWS Site-to-Site VPN connection connects the VPC to the on-premises network. The company already hosts the onprem.mydc.com domain name on premises.
The company wants to host the myvpc.example.com domain name in the company’s AWS account and resolve it to the VPC. The company also needs the on-premises devices to resolve DNS queries to the myvpc.example.com domain.
Which combination of steps will meet these requirements? Select THREE.
