An administrator needs to deploy several virtual machines. Storage contention between the virtual machines should be managed by the VMkernel.
Some of the virtual machines will use MSCS and should be highly available across the ESXi 5.5 hosts.
Which two storage options meet these requirements? (Choose two.)
A. iSCSI
B. NFS
C. Fibre Channel
D. vSAN
Correct Answer: AC
Explanation/Reference:
Explanation:
You can create a MSCS cluster that consists of two or more virtual machines on two ESXi or more hosts.
A cluster across physical hosts requires specific hardware and software.
ESXi hosts that have the following:
Two physical network adapters dedicated to the MSCS cluster and to the public and private networks.
One physical network adapter dedicated to the VMkernel.
Supported storage configuration.
ESXi 5.5 supports iSCSI for Windows Server 2008 SP2, Windows 2008 R2 SP1 and Windows 2012 server. Windows Server 2003 is not supported.
ESXi 5.5 supports FCoE (Fibre Channel over Ethernet) for Windows Server 2008 SP2, Windows Server R2 SP1 and Windows 2012 server GOS only.
Windows Server 2003 is not supported.
Incorrect Answers:
B: NFS is not supported for MSCS clusters across physical hosts. Therefore, this answer is incorrect.
D: vSAN (Virtual SAN) is not supported for MSCS clusters across physical hosts. Therefore, this answer is incorrect.
