A financial services company is migrating its high-frequency trading application to a new 6-node vSAN 8 ESA All-Flash cluster. A primary design requirement is to ensure the lowest possible I/O latency for VMDKs while providing resilience against a single host failure. The architect must select the most appropriate storage policy settings to meet this stringent performance goal. Which storage policy configuration will provide the lowest latency for this workload?
An administrator is troubleshooting a vSAN stretched cluster where VMs on the preferred site have lost connectivity to their storage. The vSAN Health service reports multiple objects as non-compliant. The witness host is online and accessible from both data sites. The network link between the two data sites is down, but the link from each site to the witness site is fully functional. What is the expected state of the VMs located on the preferred site?
A vSAN administrator is alerted to poor VM performance after a storage controller firmware update on one host in a 5-node hybrid cluster. The vSAN Performance service shows high read latency for VMs running on the updated host. All other hosts are performing normally. The administrator suspects an issue with the updated firmware or driver. Which TWO actions should the administrator take first to diagnose the problem? (Select TWO)
True or False: When enabling vSAN Data-At-Rest Encryption, the Key Management Server (KMS) must be located within the vSAN cluster it is managing to ensure key availability during a full cluster restart.
**Case Study:** A retail company is planning to deploy a new point-of-sale (POS) data processing application across 50 stores. Each store will have a 2-node vSAN cluster. Due to budget constraints, the company wants to use a single, centralized witness host appliance to serve all 50 stores. The stores are connected to a central data center via a stable WAN with an average round-trip time (RTT) of 150ms. The IT team is concerned about the scalability and viability of using a single witness appliance for all 50 clusters. The storage architect must validate the design against VMware's recommendations and requirements. Which factor poses the most significant risk to this proposed design?
An administrator needs to configure a vSAN storage policy for an archive workload where storage efficiency is the highest priority. The cluster has 8 nodes. Data availability must be maintained during a single host failure. Which configuration should be used?
A vSAN administrator is reviewing the capacity dashboard and notices the 'What if analysis' for a RAID-1 (Mirroring) policy shows significantly less usable space than expected. The cluster has deduplication and compression enabled. What is the most likely reason for this discrepancy?
An administrator is tasked with decommissioning a host from a vSAN cluster. The administrator right-clicks the host and selects Maintenance Mode. Which data evacuation option should be chosen to permanently remove the host and its data from the cluster?
A vSAN administrator is investigating a cluster-wide performance degradation. Using the `vsantop` command-line utility, the administrator observes high congestion values (>200) for several hosts in the 'Backend' section. What does this metric typically indicate?
When designing a vSAN Stretched Cluster, what are the maximum supported Round Trip Time (RTT) latency values for the following network paths? 1. Between the two main data sites. 2. Between each data site and the witness site.
