Topic 1 Question 876
2 つ選択A company hosts an application on Amazon EC2 instances that run in a single Availability Zone. The application is accessible by using the transport layer of the Open Systems Interconnection (OSI) model. The company needs the application architecture to have high availability.
Which combination of steps will meet these requirements MOST cost-effectively?
Configure new EC2 instances in a different Availability Zone. Use Amazon Route 53 to route traffic to all instances.
Configure a Network Load Balancer in front of the EC2 instances.
Configure a Network Load Balancer for TCP traffic to the instances. Configure an Application Load Balancer for HTTP and HTTPS traffic to the instances.
Create an Auto Scaling group for the EC2 instances. Configure the Auto Scaling group to use multiple Availability Zones. Configure the Auto Scaling group to run application health checks on the instances.
Create an Amazon CloudWatch alarm. Configure the alarm to restart EC2 instances that transition to a stopped state.

AnswerBD There is no information about the ports numbers and only that means that we need to use NLB, ALB is only for HTTP hence there is no point of using that solution as connection can be done via any port for exampl 4000 Autoscaling with instances in multiple AZ is the best solution. it will allow run new EC2 if it fail and in case if whole AZ will go down we will have 2nd one.

No word about the HTTP/application layer, only OSI 4 - TCP > B, an NLB should be enough D: for Autoscaling.

transport layer means just NLB.
