Which of the following are requirements for creating an Enhanced vMotion Compatibility cluster in vSphere?

Creating an Enhanced vMotion Compatibility (EVC) cluster in vSphere is primarily focused on ensuring that the processors of the hosts within the cluster present a consistent feature set to virtual machines, enabling seamless vMotion operations. The correct answer highlights the importance of "Hosts" and "Applications" related options, as these factors are pivotal to maintaining compatibility among different CPU architectures and ensuring that the applications running on the VMs do not experience interruptions during migrations.

When setting up an EVC cluster, administrators must pay close attention to the CPU features available across the hosts, ensuring that they fall under a unified compatibility baseline. This allows for the various processor generations to work harmoniously, thus enabling vMotion capabilities across different hosts without the risk of incompatibility.

Other factors such as CPU type, speed, and storage configurations play a role in the overall environment's performance and efficiency, but they are not specific requirements for establishing EVC compatibility. Additionally, network bandwidth indeed impacts the performance of vMotion processes but does not influence the establishment of the EVC cluster itself. Therefore, focusing on the hosts' characteristics and application-related options is essential for successfully creating and managing an EVC cluster in vSphere.
