Recently, an administrator noticed that one host shows the datastore as "Inactive" while the other host can access it normally. The administrator verifies that both hosts have connectivity to the SAN, the LUN is visible to both hosts, and the storage array reports the LUN as online.

A company uses vSphere 8 with a vSAN cluster consisting of 4 ESXi hosts. Each host has a single disk group with one 400 GB NVMe cache SSD and two 2 TB capacity SSDs. The vSAN cluster is used to host a mix of production VMs and test VMs. During peak business hours, the vSAN performance service shows high write latency (over 30 ms) for several production VMs, while test VMs are not affected. The administrator examines the vSAN performance charts and notices that the disk groups are not balanced: one disk group shows over 80% used capacity and high congestion, while the others are below 40%. The administrator wants to improve performance without adding new hardware or changing the storage policy. The vSAN health service reports no errors. Which action should the administrator take first?

A company has a vSphere cluster consisting of 8 ESXi hosts connected to a single Fibre Channel SAN array. They use VMFS6 datastores to store virtual machine files. The storage administrator has scheduled a firmware upgrade for the SAN array that requires a controller reboot. This will cause a temporary loss of connectivity to one LUN (datastore) for approximately 5 minutes. The datastore hosts 15 production VMs, including critical database servers. The cluster has sufficient spare capacity on other datastores, but the VMs are large (each about 200 GB). The vSphere administrator must ensure that these VMs remain available during the upgrade. The cluster has vSphere HA enabled with default settings. What should the administrator do to meet the requirement?

An administrator manages a vSAN cluster with 5 ESXi hosts in a single failure domain. The cluster uses vSAN version 8 and is configured with a single disk group per host. A storage policy is applied to a group of VMs with 'Number of failures to tolerate = 1' and 'Primary level of failures = Host'. One host experiences a catastrophic hardware failure and is now marked as 'Absent' in the vSAN cluster. The administrator checks the vSAN health and finds that the affected host's disk group is completely lost. One of the VMs from that group previously had two replicas on different hosts and a witness component on a third host. The VM is still powered on, and the administrator sees that one replica was on the failed host. The other replica and witness are on surviving hosts. What is the current state of this VM regarding data accessibility?

A vSphere administrator is deploying VMs on a vSAN cluster with 6 hosts. Each host has two disk groups, each with one cache SSD and four capacity SSDs. The administrator applies a storage policy using RAID 5 erasure coding with Number of failures to tolerate set to 1. After some time, the administrator notices that several VMs are showing compliance status as 'Non-compliant'. Investigating further, the administrator finds that on one host, the cache SSD of the first disk group has failed. The capacity SSDs in that disk group are still functional. The vSAN cluster still has sufficient overall capacity and the health service shows no other issues. What is the most likely reason for the VMs' non-compliance?

The PSP is set to Round Robin with IOPS limit of 1000. The SATP is VMW_SATP_ALUA. The storage administrator confirms that the array is in active-active mode. What should the administrator do to improve performance?
