VMware Updated 2V0-16.25 Exam Questions and Answers by hadley

ForiSCSI multipathing with ALUAandhigh performancein ESXi:

1 vSwitch with 2 Uplinks→ Standard design for redundancy and multipathing. (B)

Add iSCSI software adapter→ Required to connect to storage. (E)

Configure two bound VMkernel ports→ Ensures multipathing (one per uplink). (G)

Set PSP to Round Robin (RR)→ Optimizes I/O balancing across multiple paths. (F)

Other options:

A. 2 vSwitches with 1 Uplink each→ Not recommended, complicates multipathing.

C. NVMe over TCP→ Not relevant, storage is iSCSI.

D. MRU policy→ Legacy, not high performance.

H. Unbound VMkernel ports→ Used for software iSCSI port binding, but "bound" VMkernel ports are required for multipathing.

Hardware abstraction in VMware virtualization:

Thehypervisor abstracts physical resources(CPU, memory, storage, networking) and presents them to VMs asstandardized virtual hardware.

This allows VMs to run independently of underlying physical devices, enabling features likevMotion and hardware independence.

Other options:

A. Encrypting data→ Security feature, not abstraction.

B. Isolating memory access→ Memory protection, not full abstraction.

C. Live migration between Intel and AMD→ Possible with compatibility modes, but not a direct definition of abstraction.

Theprimary purpose of vSphere Lifecycle Manager (vLCM)is to:

Update, patch, and upgrade ESXi hosts, firmware, and drivers.

Manage host consistency across clusters withimage-based lifecycle management.

Other options are unrelated:

A. Configure network settings→ Done through vCenter or host client, not vLCM.

B. Monitor performance→ Done in vCenter/VCF Operations, not vLCM.

C. Create/manage VMs→ Managed through vCenter, not vLCM.

InVCF Operations for Logs(formerly vRealize Log Insight):

ThePrimary Nodeis responsible forcoordinating the overall functioning of the cluster, including configuration management and directing traffic.

Worker/Data Nodeshandle log ingestion and query execution.

Replica Nodeprovides HA for the Primary Node but does not act as the main coordinator.
