D-UN-DY-23 practice question 5 of 10

Which are two features of the Dell UnityVSA? (Choose two.)

Full set: 41 questions
Answer options
A: NVMe Connectivity
B: iSCSI Connectivity Correct answer
C: Asynchronous Replication Correct answer
D: FC Connectivity
E: Dynamic Pools
Correct Answer:
B. iSCSI Connectivity; C. Asynchronous Replication
Explanation

The Dell UnityVSA (Virtual Storage Appliance) is a software-defined version of the Unity XT platform that runs as a virtual machine. It provides core data services and connectivity options suitable for virtual environments. It fully supports block access over IP networks using the iSCSI protocol. Additionally, it includes native asynchronous replication capabilities, allowing data from file systems and LUNs to be replicated to another UnityVSA or a physical Unity XT array for disaster recovery purposes.

Why Incorrect

A. NVMe Connectivity is a hardware-level feature for high-performance flash access that is not available in the software-only, virtualized UnityVSA platform.
D. FC (Fibre Channel) Connectivity requires dedicated hardware (HBAs), which a virtual appliance like UnityVSA does not have. All its connectivity is through the hypervisor's virtual network interfaces.
E. Dynamic Pools are an advanced pooling technology available on physical Dell Unity XT hardware arrays to optimize performance and capacity; this feature is not supported on UnityVSA.

1. Dell UnityVSA Datasheet (dell-unity-vsa-datasheet.pdf). The datasheet lists "iSCSI" under supported protocols and "Native Asynchronous Block & File Replication" under Data Protection features. It does not list FC, NVMe, or Dynamic Pools.

2. Dell White Paper: "Dell Unity: Introduction to the Unity Platform" (H15093.7). Page 10, Table 2 "Dell Unity models". This table compares the physical and virtual models, showing that UnityVSA supports iSCSI and Replication but lacks hardware-dependent features like FC.
