2V0-621 · Question #247

Click the Exhibit. Which three conditions would explain the error? (Choose three.)

The correct answer is A. EVC is using a newer baseline than the hosts in the Exhibit. B. The ESXi hosts have an incompatible version of Streaming SIMD Extensions (SSE). C. The ESXi hosts have the Intel No-Execute feature disabled. EVC errors occur when the cluster baseline requires CPU features that the ESXi hosts do not support or do not have enabled.

Why each option

EVC errors occur when the cluster baseline requires CPU features that the ESXi hosts do not support or do not have enabled.

AEVC is using a newer baseline than the hosts in the Exhibit.Correct

A newer EVC baseline requires CPU features beyond what the installed hosts support, causing a compatibility mismatch that prevents the hosts from satisfying the cluster's CPU feature mask.

BThe ESXi hosts have an incompatible version of Streaming SIMD Extensions (SSE).Correct

EVC baselines include SSE feature requirements; if a host's SSE version is incompatible with the baseline, the host cannot satisfy the CPU feature mask required by EVC.

CThe ESXi hosts have the Intel No-Execute feature disabled.Correct

EVC baselines require the Intel NX/XD (No-Execute) bit to be enabled; if this feature is disabled in the host BIOS, the host fails EVC compatibility validation.

DEVC is using an order baseline than the hosts in the Exhibit.

An older EVC baseline is less restrictive and only uses a subset of the hosts' CPU capabilities, so it would not generate a compatibility error.

EThe EXSi host does not have the Intel VT-d feature enabled.

VT-d (Intel Virtualization for Directed I/O) enables PCIe device passthrough and is not part of the EVC CPU feature mask or baseline requirements.
