Actual exam question from VMware's 3V0-624

Question #: 44
Topic #: 1

An architect is designing a vSphere 6.5 implementation.
✑ The customer requires Cross vCenter vMotion for the newly-created data centers in New York and Houston
Each data center will use different IP networks for management and vMotion

When creating a vMotion network, which two statements are required in order to use Cross vCenter Server vMotion? (Choose two.)

A. vMotion Networks in both data centers must be in the same L2 stretched VLAN.
B. The virtual machine port groups must use the same name.
C. VMkernel port for vMotion must be configured with vMotion TCP/IP stack with correct gateway.
D. vMotion networks in both data centers must be routable over L3 network.

C and D. As each datacentre uses different network, vMotion traffic should be able to route to the other side. https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.vcenterhost.doc/GUID-5211FD4B-256B-4D9F-B5A2-F697A814BF64.html#GUID-5211FD4B-256B-4D9F-B5A2-F697A814BF64

BC according to this: https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.vcenterhost.doc/GUID-3B41119A-1276-404B-8BFB-A32409052449.html Network Configuration Configure the virtual networks on vMotion enabled hosts as follows: On each host, configure a VMkernel port group for vMotion. To have the vMotion traffic routed across IP subnets, enable the vMotion TCP/IP stack on the host. See Place vMotion Traffic on the vMotion TCP/IP Stack of an ESXi Host. If you are using standard switches for networking, ensure that the network labels used for the virtual machine port groups are consistent across hosts. During a migration with vMotion, vCenter Server assigns virtual machines to port groups based on matching network labels.

C & D Ive personally done this 3x times for migrations. If you examine the logs, The VMware API's do not call on IP's. They call on the resolvable names given to the hosts as they are added in vCenter. Therefore, if a VM on host NY01 needs to be to a host called HOU01, NY01 must be able to resolve HOU01 and vice versa. Since they are already on separate subnets, creating a tunnel with proper routes/access-lists coupled with an up-to-date DNS source would allow the vCenters and Hosts to resolve each other and vMotion VM's.

A. vMotion Networks in both data centers must be in the same L2 stretched VLAN. This is not accurate, although it does make the VMware Engineer's life a hell of a lot simpler it is not a "must"

Afterthought , VM's will not vMotion automatically if the Portgroups do not share the same name.

I think a,d. seperate tcp/ip stack is not a must. same L2 network makes VM service remains after vmotion. No change on IP and DNS record.

L2 won't fit in this scenario since there are two different networks. C & D

a - no, b - no. esxi 6.5 supports network(portgroup), compute and storage migration. so C and D are correct. gateway and network shlould be at Layer 3
