2V0-621D · Question #49

Which three traffic types can be configured for dedicated VMkernel adapters? (Choose three.)

The correct answer is B. vMotion traffic C. vSphere Replication NFC traffic D. Provisioning traffic. VMkernel adapters are used by ESXi hosts for specific management and operational traffic, and common types that can be dedicated include vMotion, vSphere Replication NFC, and Provisioning traffic.

Why each option

VMkernel adapters are used by ESXi hosts for specific management and operational traffic, and common types that can be dedicated include vMotion, vSphere Replication NFC, and Provisioning traffic.

ADiscovery traffic

Discovery traffic is not a standard, configurable VMkernel adapter traffic type in vSphere; discovery typically refers to general network protocols or storage array discovery.

BvMotion trafficCorrect

vMotion traffic allows live migration of virtual machines between ESXi hosts, and a dedicated VMkernel adapter is recommended for this high-bandwidth, latency-sensitive traffic to ensure smooth operations.

CvSphere Replication NFC trafficCorrect

vSphere Replication NFC (Network File Copy) traffic is used for replicating virtual machine data between hosts for disaster recovery purposes, and it often utilizes a dedicated VMkernel adapter for isolation and performance.

DProvisioning trafficCorrect

Provisioning traffic includes tasks like virtual machine creation, cloning, and snapshots, which can involve significant data transfer and can be assigned to a dedicated VMkernel adapter for performance optimization and network isolation.

EvSphere Custom traffic

vSphere Custom traffic is not a predefined or configurable traffic type for VMkernel adapters in vSphere, though administrators can create VMkernel adapters for various purposes.
