How can the administrator accomplish this with the LEAST administrative overhead?

Use Amazon CloudFront to log the URL and forward the request.

Use Amazon CloudFront to rewrite the header based on the microservice and forward the request.

Use an Application Load Balancer (ALB) and do path-based routing.

Use a Network Load Balancer (NLB) and do path-based routing.

Question 7

A company is running a flash sale on its website. The website is hosted on burstable performance Amazon EC2 instances in an Auto Scaling group. The Auto Scaling group is configured to launch instances when the CPU utilization is above 70%.

A couple of hours into the sale, users report slow load times and error messages for refused connections. A SysOps administrator reviews Amazon CloudWatch metrics and notices that the CPU utilization is at 20% across the entire fleet of instances.

The SysOps administrator must restore the website's functionality without making changes to the network infrastructure. Which solution will meet these requirements?

Activate unlimited mode for the instances in the Auto Scaling group.

Implement an Amazon CloudFront distribution to offload the traffic from the Auto Scaling group.

Move the website to a different AWS Region that is closer to the users.

Question 9

A SysOps administrator is evaluating Amazon Route 53 DNS options to address concerns about high availability for an onpremises website. The website consists of two servers: a primary active server and a secondary passive server. Route 53 should route traffic to the primary server if the associated health check returns 2xx or 3xx HTTP codes. All other traffic should be directed to the secondary passive server. The failover record type, set ID, and routing policy have been set appropriately for both primary and secondary servers.

Which next step should be taken to configure Route 53?

Create an A record for each server. Associate the records with the Route 53 HTTP health check.

Create an A record for each server. Associate the records with the Route 53 TCP health check.

Create an alias record for each server with evaluate target health set to yes. Associate the records with the Route 53 HTTP health check.

Create an alias record for each server with evaluate target health set to yes. Associate the records with the Route 53 TCP health check.
