What combination of the following should be used to ensure the highest network performance (packets per second), lowest latency, and lowest jitter? Choose 3 answers A.Amazon EC2 placement groups B.Enhanced networking C.Amazon PV AMI D.Amazon HVM AMI E.Amazon Linux F.Amazon VPC Amazon EC2 placement groups – Placement groups, especially cluster placement groups, are designed to achieve low-latency and high-throughput network performance by placing EC2 instances close to each other. Enhanced networking – Enhanced networking uses SR-IOV (Single Root I/O Virtualization) to provide higher I/O performance and lower latency for EC2 instances. Amazon HVM AMI – HVM (Hardware Virtual Machine) AMIs provide better performance than PV (Paravirtual) AMIs, especially when combined with enhanced networking.

A.Yes, using the AWS multi-factor token devices to authenticate users on the AWS platform. B.No, you cannot integrate multi-factor token devices with the AWS platform. C.Yes, you can integrate private multi-factor token devices to authenticate users to the AWS platform. Send an SNS notification, if configured to do so. Terminate an instance in the AZ which currently has 2 running EC2 instances. Explanation: SNS Notification: Auto Scaling can be configured to send an SNS notification when an instance is launched or terminated. This allows administrators to monitor and track Auto Scaling activities. Terminate in the AZ with More Instances: By default, Auto Scaling tries to maintain balance across Availability Zones (AZs). If there is an imbalance, Auto Scaling terminates instances in the AZ with the highest number of running instances to maintain even distribution.

B.Instance-store backed instances can be stopped and restarted. C.Auto scaling requires using Amazon EBS-backed instances. D.Virtual Private Cloud requires EBS backed instances. Answer:A Amazon EBS-backed instances can be stopped and restarted. Explanation: Amazon EBS-backed instances: Can be stopped and restarted without losing data stored on the root volume. The root volume is stored on Amazon EBS, which is persistent storage. Instance-store backed instances: Cannot be stopped and restarted — they can only be terminated and data on the instance store is lost when the instance is stopped or terminated. The root volume is stored on ephemeral instance storage, which is temporary.
