                                            Question #3

                                            An organization has two vSAN clusters managed by the same vCenter server, each providing 100 TB of storage. The first cluster runs at 75% of its storage capacity, and the second cluster runs at 40% of its storage capacity.
                                            The company also has the following:
                                            * an iSCSI array of 300 TB, which runs at 76% of its capacity
                                            * a NAS system of 200 TB, which runs at 10% of its capacity
                                            * a Fiber channel (FC) array of 300 TB, which runs at 80% of its capacity The administrator is asked to add an additional 25 TB of storage to the first cluster but is also made aware that there is no budget to purchase new hardware and that the vSAN Storage Policy Based Management must be kept in place.
                                            Which storage option will work for this use case?

                                            • A. Use the FC array to obtain additional free capacity.
                                            • B. Use the iSCSI array to obtain additional free capacity.
                                            • C. Use the NAS to obtain additional free capacity.
                                            • D. Use an HCI Mesh to obtain additional capacity.
