A company runs a real-time data processing application on EC2 instances. The application requires very low latency between instances. The instances are currently in different Availability Zones. The network engineer wants to reduce latency. Which change should be made?

Enable enhanced networking on the instances but keep them in different AZs.

Use a Network Load Balancer in front of the instances.

Use a spread placement group across the current AZs.

Move the instances to the same Availability Zone and place them in a cluster placement group.

A company runs a mission-critical application on EC2 instances in a single Availability Zone. The application must be highly available and have a recovery time objective (RTO) of less than 15 minutes. The company has a limited budget. Which solution should be implemented?

Use a multi-region disaster recovery solution with Route 53 failover.

Enable detailed monitoring on the instance and set up a CloudWatch alarm to notify the on-call engineer.

Deploy a second set of EC2 instances in another AZ and use an Application Load Balancer to distribute traffic.

Create an AMI of the instance and use it to launch a new instance in another AZ when a failure occurs.

Which AWS feature is used to provide higher packet-per-second performance and lower latency for network-intensive EC2 instances?
