2v0-3322 Exam - Question 14

A customer is looking to leverage a VMware Public Cloud solution to provide them with additional compute capacity as seasonal demand increases for their online business.

The current on-premises data center is configured as follows:

VMware vSphere 7.0 -

VMware vSphere Distributed Switch (vDS) 7.0

Management and Server network - 172.18.0.0/16

vMotion network - 192.168.120.0/24

250 application servers

Given the information in the scenario, which capability of VMware HCX will the customer not be able to utilize?

Show Answer
Correct Answer: B

Given the scenario where the customer needs to leverage VMware Public Cloud solutions for additional compute capacity, the specific configuration of their on-premises data center—particularly the management and server network being on the same subnet—presents challenges. VMware HCX Layer 2 extension requires compatibility with the existing network setup, and vSphere infrastructure networks like ESXi VMkernel cannot be extended. Therefore, the customer will not be able to utilize the Layer 2 extension capability of VMware HCX.

I think the correct answer is B. In this case, Management and Servers are in the same network, but vSphere infrastructure networks cannot be extended: https://docs.vmware.com/en/VMware-HCX/4.6/hcx-user-guide/GUID-DBDB4D1B-60B6-4D16-936B-4AC632606909.html

Management network can not be stretched.

correct answer is B. To utilize the Layer 2 extension feature of VMware HCX, a vSphere Distributed Switch (vDS) is required in both the on-premises and VMware Cloud on AWS environments. However, as stated in the scenario, the on-premises environment already has a vDS in place. Therefore, this feature can be utilized.

B. Layer 2 extension Management “and Server” network - 172.18.0.0/16 “and Server” being the 250 application servers. https://docs.vmware.com/en/VMware-HCX/4.6/hcx-user-guide/GUID-DBDB4D1B-60B6-4D16-936B-4AC632606909.html Detected and Restricted Source Network Types The HCX Network Extension service detects and prevents several non-supported Network Extension scenarios (items are dimmed in the Network Extension UI): • vSphere infrastructure networks (ESXi VMkernel networks).

Management and Server subnet is using a shared network subnet which will causing network outage. "Virtual machine networks with shared or overlapping VLAN configurations must not be extended to the same destination router. This can result in a network outage."

Bulk is not supported on vSphere 7.0 according to: https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vmc-aws-operations/GUID-36261B1A-6DBF-4D56-A6D9-C97E1E857409.html

Given the scenario, one notable piece of information is the version of VMware vSphere being used: vSphere 7.0. last update, HCX doesn't support vMotion-based migrations (like Bulk migration) with VMware vSphere 7.0. Therefore, the correct answer is: C. Bulk migration Bulk migration leverages vMotion and is primarily used to move multiple virtual machines without downtime, but given the version incompatibility, the customer would not be able to utilize this feature with vSphere 7.0. The other features, like cold migration, layer 2 extension, and WAN optimization, do not have this specific limitation.

I would say B as Management network shouldn't/can't be extended

Layer 2 extension is not a capability of HCX. neither is Wan Optimization. The correct answer is A. Cold migration because the customer cannot turn off their local datacenter.

A /16 subnet IMHO would be too large to be stretched to AWS. On top it's not supported to have management (vmKernelPorts) and servers (the 250 VMs) in the same segment.

IAZZUSOption: B

B. Layer 2 extension. The customer's current network setup may not support the Layer 2 adjacency required for VMware HCX Layer 2 extension without additional configuration.
