Question: 1/50
An SAP NetWeaver ASCS and ERS pair is deployed on Amazon EC2. The operations team needs a highly available virtual IP for the ASCS instance that can move automatically during failover. Which AWS-recommended approach should be used?
Assign an Elastic IP address to the ASCS instance and reassociate it on failover using a Lambda function
Use an Amazon Route 53 weighted record to distribute traffic across ASCS and ERS instances
Use an AWS Elastic Load Balancer in front of ASCS and ERS and route based on TCP port
Use a secondary private IP address on the ENI and move it between instances during failover using the AWS CLI or API (typically via cluster hooks)
