A cloud administrator is looking to migrate several dozen workloads from their on-premises location to a VMware public cloud using VMware HCX. A total of nine networks will need to be stretched for the migration. They will also be utilizing the capabilities of the WAN appliance for the migration.

HCX appliance requirements are as follows:

• HCX Manager: 4 vCPU, 12GB Memory

• HCX-IX Interconnect: 8 vCPU, 3GB Memory

• HCX Network Extension: 8 vCPU, 3GB Memory

• HCX WAN Optimization: 8 vCPU, 14GB Memory

What are the on-premises vCPU and memory component requirements for this VMware HCX deployment?

    Correct Answer: A

    The required vCPU and memory for each HCX appliance are as follows: HCX Manager: 4 vCPUs, 12GB Memory; HCX-IX Interconnect: 8 vCPUs, 3GB Memory; HCX Network Extension (for nine networks, an additional appliance is required): 8 vCPUs, 3GB Memory each (total of two appliances here is needed, 16 vCPUs, 6GB Memory); HCX WAN Optimization: 8 vCPUs, 14GB Memory. Adding these up, the total requirement is 36 vCPUs and 35GB of memory, hence the correct answer is 36 vCPUs, 35GB of memory.
