Topic #: 1
[All 3V0-21.21 Questions]

An architect is designing a VMware solution for a customer based on the following information:
✑ The solution must use investments in existing storage array that supports both block and file storage.
✑ The solution must support the ability to migrate workloads between hosts within a cluster.
✑ The solution must support resource management priorities.
✑ The solution must support the ability to connect virtual machines directly to LUNs.
✑ The solution should use existing IPv4 based network infrastructure.
✑ There is no budget for additional physical hardware.
Which two design decisions could the architect make to meet these requirements? (Choose two.)

  • A. The ESXi hosts will leverage Fibre Channel (FC)
  • B. The ESXi hosts will leverage NFS 3
  • C. The ESXi hosts will leverage Fibre Channel over Ethernet (FCoE)
  • D. The ESXi hosts will leverage iSCSI
  • E. The ESXi hosts will leverage NFS 4.1

I'd say B and D: NFS 3 and iSCSI FC is not IP NFS4.1 does not support I/O control https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-8A929FE4-1207-4CC5-A086-7016D73C328F.html Starting from vSphere 7.0, VMware no longer supports software FCoE in production environments. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-6B49866F-7005-4099-84AC-4FB2A1A91F64.html

Must be C and D. FC is not IP NFS does not support RDMs (direct access to LUNs) Only Software FCoE is not support anymore. Not FCoE in general

I need to correct my given answer: Following the requirement: the solution must support block and file storage The answer must be B NFS 3 for file and D iSCSI for Block.

"existing storage array that supports both block and file storage" It's the existing array who supports block and file. There is no prerequisite concerning the solution on that point.

Answers are C & D, which are the only possible solutions for using RDM on an IPv4 network A >> FC does not use the IPv4 network infrastructure, it needs a SAN B >> No RDM on NFS 3 C >> FCoE almost the same things as FC, but through IPv4 network (and the proper hardware of course) D >> Of course, you can use RDM on iSCSI (Demo here : https://www.starwindsoftware.com/blog/vmware/rdm-disks-vmware-vsphere-vms-create/) E >> No RDM on NFS 4.1.

RDM is not supported by NFS, and that knocks both versions out. FC violates Req 5. That leaves us with 2 answers verified here: KB / Table 2. https://kb.vmware.com/s/article/79616

A. FC does not use IP C. Starting from vSphere 7.0, VMware no longer supports software FCoE in production environments. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-6B49866F-7005-4099-84AC-4FB2A1A91F64.html E. NFS 4.1 does not support Storage IO Control https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-8A929FE4-1207-4CC5-A086-7016D73C328F.html

The answer is always NFS and iSCSI. There are many Storage systems that support both, so only one system will be needed here. The question is NFS v3 or NFS v4.1, I will vote E for v4.1

Selected Answer: CD
C and D obviously. "The solution must support the ability to connect virtual machines directly to LUNs." - this rules out non-block storage. "The solution should use existing IPv4 based network infrastructure." - this rules out FC. Left are iSCSI and FCOE, both is IPv4-based block storage.
