For the source and destination host to have shared access to the storage that contains the VM, they must be able to access the same datastore. This requires that the datastore be available to both hosts and that the datastore has the same name on both hosts.

The status of VMware Tools on the VM should also be checked before performing a hot migration. VMware Tools is a suite of utilities that enhances the performance of a virtual machine's guest operating system and improves the management of the virtual machine. If VMware Tools is not installed or not up to date, the hot migration may fail.

Finally, the status of the guest operating system in the VM should also be checked before performing a hot migration. The guest operating system should be up and running and not in a suspended state. If the guest operating system is in a suspended state, the hot migration may fail.

The CPU instruction set required by the VM and the vGPU configuration of the VM are not items to consider when performing a hot migration of a virtual machine. The source and destination host management network IP address families do not need to match for the hot migration to be successful.

When a VPN is established between the data center and the SDDC Instance, it allows the organization to create a private and secure connection between their on-premises infrastructure and their workloads running in the cloud. By advertising a 0.0.0.0/0 route, the organization is essentially routing all traffic to the VPN tunnel, which means that all traffic including traffic destined for the data center and internet traffic, will be sent through the VPN tunnel to the company's data center.

It is important to note that this configuration depends on the company's network architecture and security policies, and that there may be other alternatives that better fit the organization's needs.

VMware Multi-Cloud Vision enables customers to deliver a consistent management and operations layer across any cloud, and to modernize applications in the cloud of choice using the cloud-native services of that cloud provider. It does not run workloads in the cloud to eliminate security issues, standardize at the DevSecOps and infrastructure level, or reduce the number of developers to increase productivity.

vCenter Mapping Mapping vCenters in a DR plan consists of selecting source vCenters that are registered to the protected site. Choosing a target vCenter for a Failover SDDC is simple; each SDDC contains a single vCenter instance. For VMware Cloud Disaster Recovery, keep in mind that a protected site can have multiple registered vCenters, but you can only map one vCenter on VMware Cloud on AWS per-DR plan. https://vmc.techzone.vmware.com/resource/introduction-vmware-cloud-disaster-recovery#inventory-and-resource-mapping https://vmc.techzone.vmware.com/resource/protection-groups-and-recovery-plans-vcdr#create-a-disaster-recovery-plan

The two steps that the cloud administrator should complete on I/O-intensive workloads to ensure the best performance possible are to configure the VMware Paravirtual SCSI (PVSCSI) adapter and to ensure that the VMware hardware version is 7 or later. The PVSCSI adapter provides improved performance and scalability compared to the LSI Logic Parallel SCSI controller. Additionally, the hardware version should be 7 or later to ensure that the virtual machine is able to take advantage of the latest features and enhancements. Enabling the memory hot-add feature and configuring a maximum of two CPU cores per socket will not improve the performance of I/O-intensive workloads.

RAID-1 is a mirror configuration that provides high availability by creating multiple copies of a VMDK. RAID-5 and RAID-6 are erasure coding configurations that provide fault tolerance by distributing data and parity across multiple hosts.

The number of failures to tolerate (FTT) determines how many copies or parity blocks are created for each VMDK. For example, RAID-1 FTT = 2 means that there are three copies of each VMDK.

Therefore, based on your requirements, a possible VM storage policy setting could be RAID-1 FTT = 2, which would provide redundancy at the highest level possible with six hosts.
