An architect is responsible for designing a VMware Cloud Foundation (VCF)-based private cloud for a
customer.
The architect noted the following requirements during a design workshop:
Co-locate application workloads with VCF management component workloads within the same vSphere
cluster.
Shared storage data is always available and 100% current in the event of a single site outage. Have two
sites available no more than 10 miles apart (10ms latency) connected with high-speed network
technology to host their virtual infrastructure.
Protect against outages of a single site designated as an availability zone.
Which two storage technologies could meet the stated requirements? (Choose two.)
Answer
- A. NVMe over TCP
- B. NVMe over Fibre Channel (FC)
- C. VMFS on Fibre Channel (FC)
- D. vSAN Correct
- E. vSphere Virtual Volumes (vVols) Correct
Explanation
According to VMware Cloud Foundation 9.0 documentation, when a stretched cluster is deployed acrosssites with sub-5ms latency and high-speed interconnects, vSAN can be configured for zero RPO
(Recovery Point Objective), ensuring 100% data consistency and availability in the event of a site failure.
vSAN supports co-locating management and application workloads and provides the shared storage
functionality with automatic failover capabilities.
Additionally, vSphere Virtual Volumes (vVols) provide granular control of virtual machine storage, and
when backed by a storage system that supports replication and failover across sites (with support for
VASA 3.0 or later), vVols can meet the same requirements for data availability and disaster recovery.
