   You are troubleshooting a performance issue in a VxRail cluster. The vSAN network is configured with jumbo frames (MTU 9000). You notice that vSAN performance is poor, and the physical switch logs show 'oversized packet' errors on the vSAN VLAN. What is the most likely cause of this issue?

   • AThe physical switch ports for the vSAN VLAN are configured with an MTU of 1500, but the VxRail nodes are sending MTU 9000 frames.
   • BThe vSAN network is experiencing high latency, causing packets to be dropped and flagged as oversized.
   • CThe vSAN network is using a different VLAN than the one configured for jumbo frames on the switch.
   • DThe vSAN VMkernel port is configured with an MTU of 1500, but the physical switch is configured for MTU 9000.

   A company is planning a VxRail cluster that will be stretched across two data centers for disaster recovery. The vSAN network will traverse a 10 Gbps link with a round-trip latency of 5 ms. The application team has stated that the VMs must remain available during a data center failure. What is the primary design constraint for this scenario?

   • AvSAN cannot operate over a 5 ms latency link; the maximum supported latency is 1 ms.
   • BThe vMotion network must be prioritized over vSAN traffic on the inter-DC link to ensure VM mobility during a failure.
   • CvSAN can operate over a 5 ms latency link, but the stretched cluster will require a witness appliance to maintain quorum.
   • DThe cluster cannot be stretched across data centers; a single data center is required for vSAN.

   A hospital is deploying a 4-node VxRail cluster. The security team mandates that VM traffic, vSAN traffic, and management traffic must be completely isolated at Layer 2. The physical switches support 802.1Q trunking. Which configuration approach satisfies the security requirement?

   • ACreate two VLANs: one for management and vSAN combined, and one for VM traffic.
   • BPlace all traffic on a single VLAN and rely on IP subnetting to separate the traffic types.
   • CUse a single VLAN but enable Private VLANs (PVLAN) on the switch to isolate traffic within the broadcast domain.
   • DCreate three separate VLANs (management, vSAN, VM) and configure the VxRail node uplinks as trunk ports carrying all three VLANs.

   You are designing a VxRail cluster that will be deployed across two buildings on a campus. The vSAN network will traverse a 1 Gbps link between the buildings. The cluster will run a latency-sensitive application. What is the primary network design consideration for this scenario?

   • AThe vMotion network should be prioritized over vSAN traffic on the inter-building link to ensure VM migration performance.
   • BThe vSAN network should be placed on a dedicated 10 Gbps or higher link with very low latency to meet performance requirements.
   • CThe cluster can be deployed across the buildings as long as the link is configured with jumbo frames to reduce latency.
   • DThe 1 Gbps link is sufficient for vSAN traffic, but the latency between buildings must be under 5 ms for vSAN to function.

   What is the purpose of configuring VLAN trunking on physical switch ports connected to VxRail nodes?

   • ATo increase the MTU of the link
   • BTo allow multiple VLANs to traverse the same physical link
   • CTo route traffic between VLANs
   • DTo provide link redundancy
