Question 25

An administrator is planning to migrate a VMware vSphere environment to VMware Cloud on AWS. A first analysis returns the following specifications:

✑ 37 virtual machines will be live migrated

✑ All virtual machines have been created using VMware vSphere 5.0 (Compatibility Version 8)

✑ All virtual machines are connected to Standard Switches

✑ The bandwidth between the local data center and VMware Cloud on AWS is 250 Mbps

What are two valid approaches for live migrating these virtual machines? (Choose two.)

A.

✑ Upgrade Virtual Machine Compatibility to Version 9.

✑ Ensure Standard Switch is named the same as the target segment in VMware Cloud on AWS.

✑ Activate and deploy VMware HCX.

✑ Let HCX configure Enhanced vMotion Compatibility (EVC) automatically.

B.

✑ Upgrade Virtual Machine Compatibility to Version 9.

✑ Configure Hybrid Linked Mode for Cross vCenter vMotion.

Configure AWS Direct Connect Private VIF.

✑ Configure Enhanced vMotion Compatibility (EVC) on the source virtual machines as required.

C.

✑ Ugrade Virtual Machine Compatibility to Version 9.

✑ Migrate the Virtual Machines to a Distributed Virtual Switch.

✑ Activate and deploy VMware HCX.

✑ Let HCX configure Enhanced vMotion Compatibility (EVC) automatically.

D.

✑ Upgrade the bandwidth between the local data center and VMware Cloud on AWS to 400 Mbps.

✑ Migrate the virtual machines to a Distributed Virtual Switch.

✑ Activate and deploy VMware HCX.

✑ Let HCX configure Enhanced vMotion Compatibility (EVC) automatically.

E.

✑ Upgrade the bandwidth between the local data center and VMware Cloud on AWS to 400 Mbps.

✑ Configure Hybrid Linked Mode for Cross vCenter vMotion.

✑ Configure AWS Direct Connect Private VIF.

✑ Configure Enhanced vMotion Compatibility (EVC) on the target software-defined data center (SDDC) as required.

    Correct Answer:

    To live migrate 37 virtual machines that were created using VMware vSphere 5.0 (Compatibility Version 8) and are connected to Standard Switches with a bandwidth of 250 Mbps between the local data center and VMware Cloud on AWS, the correct approaches are: B and C. This is because live migration with VMware HCX requires a Distributed Virtual Switch, and 250 Mbps bandwidth is sufficient for the migration. Option B involves configuring Hybrid Linked Mode and AWS Direct Connect while ensuring EVC compatibility, and Option C involves migrating the VMs to a Distributed Virtual Switch and using VMware HCX.

A - No standard switch support for live migration B - CORRECT, has enough BW, 250Mbps C - CORRECT, HCX only needs 100Mbps D - Doesn't address HW version E - Do not need to upgrade BW

250MB bandwidth per concurrent vMotion, so not D or E. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vcenterhost.doc/GUID-3B41119A-1276-404B-8BFB-A32409052449.html HCX supports standard switch, but cannot see requirement to name the segment the same anywhere. Makes more sense than migrating to VDS if you dont have to, so going with A, B. https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vmc-aws-operations/GUID-DAE9B318-294A-4422-BBF4-82AE9DDFF043.html

"37 virtual machines will be LIVE migrated" Live migration requires distributed switch...

Dmytros

BC& is correct In LIVE Migration Need DVS: On-premises DVS version 6.0 or higher. https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vmc-aws-operations/GUID-1A175E91-2317-4261-A63E-B398D92ECE8D.html

Cccb35

I think, the corrects are B and C. https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vmc-aws-operations/GUID-6EC9D234-6B9D-4C66-9385-D6AB3BFFFBC9.html

A - NO - Standard switches won't extend L2, so no Live migration - Naming doesn't matter - HCX does not change EVC and neither does vMotion. B - Weird - Cross vCenter vMotion won't be "live" as there wouldn't be an L2 stretch, unless you're happy to migrate and have no destination network that would function for the VM. (maybe this one technically?) C - Weird - HCX doesn't configure EVC - You can configure evc on a per VM basis on-prem though. If the VM was on a distributed switch you could use L2 stretch, but thats not mentioned. D - Werid - Bandwidth minimum for HCX to work is 100 mbps. HCX does not change EVC - Sure, you can take a VM running on old and move it to new, but thats only because it's using CPU instructions the new hosts fully understands. E - NO - You can't change EVC settings on an SDDC cluster. Bandwidth is fine. If i was forced to pick the least worse two answers, it would be B and C

B - C : HCX Network Extension does not support the following source configurations: vSphere Standard Switch (VSS) networks.

Cobra005

B&C as BW is sufficient and because HCX Network Extension does not support the following source configurations: vSphere Standard Switch (VSS) networks. https://docs.vmware.com/en/VMware-HCX/4.5/hcx-user-guide-45.pdf

BD NOT A: Standard sw naming doesn't matter NOT C: don't have enough BW per migration E: don’t have to configure EVC on target SDDC Deploy, Configure, Manage 2021 8-31 Live Migration Using Hybrid Linked Mode VM is powered on. Source to destination settings are as follows: — Bandwidth of 250 Mbps (per migration) Networking settings are configured: — IPsec VPN to management gateway — L2 VPN or AWS Direct Connect — vSphere Distributed Switch 6.x or later VM Compatibility version 9 is used. Enhanced vMotion Compatibility is considered. Each live migration requires 250 Mbps of bandwidth per vSphere vMotion migration

Rabbit117

I think A and B are correct. You would need to upgrade VM compatibility to v9 and the bandwidth is already 250Mbps so that is D and E out. No need to migrate the VMs to DVS as Standard switches are supported, so that rules out C.

HCX Network Extension does not support the following source configurations: vSphere Standard Switch (vSS) networks. https://docs.vmware.com/en/VMware-HCX/4.8/hcx-user-guide/GUID-DBDB4D1B-60B6-4D16-936B-4AC632606909.html#GUID-DBDB4D1B-60B6-4D16-936B-4AC632606909

balabharath

cross vcenter vmotion is not supported in 5.0. So B is invalid. A &C is right because it upgrades VM hardware. In D&E upgrading VM hardware is not listed. Also 400Mbps is not required. 250Mbps is the min.requirement.

SDDC_Guy

Only says it was created in 5.0, for purpose of saying HW8. B/C

rembix

A & B VSS is supported on HCX https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vmc-aws-operations/GUID-DAE9B318-294A-4422-BBF4-82AE9DDFF043.html

BoDaddy

I don't think you need to upgrade the bandwidth to 400mb and Standard Switches are supported in HCX , So I am going with A & B

Rabbit117

Standard switch is supported. See https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vmc-aws-operations/GUID-DAE9B318-294A-4422-BBF4-82AE9DDFF043.html
