Which of the following can help to create dual-homed instances with workloads/roles on distinct subnets.
Click on the arrows to vote for the correct answer
A. B. C. D.The correct answer is C. Multiple network interfaces.
Dual-homed instances are instances that have multiple network interfaces, each attached to a different subnet. They are typically used to provide high availability and fault tolerance for critical workloads.
A. Multiple EBS Volumes: EBS volumes are block-level storage devices that can be attached to EC2 instances. While multiple EBS volumes can be attached to an instance, they are not directly related to creating dual-homed instances with workloads on distinct subnets.
B. Multiple VPCs: A Virtual Private Cloud (VPC) is a logically isolated section of the AWS Cloud that can be used to launch resources in a virtual network. Multiple VPCs can be created in AWS, but they are not directly related to creating dual-homed instances with workloads on distinct subnets.
C. Multiple network interfaces: Each network interface can be associated with a different subnet, allowing a single instance to be connected to multiple subnets. This is the recommended way to create dual-homed instances with workloads on distinct subnets.
D. Multiple S3 buckets: Amazon S3 is a highly scalable object storage service that can be used to store and retrieve data. Multiple S3 buckets can be created in AWS, but they are not directly related to creating dual-homed instances with workloads on distinct subnets.
Therefore, the correct option is C. Multiple network interfaces.
