5V0-22.23 Exam Dumps : VMware vSAN Specialist v2

To deploy a new two-node vSAN cluster with a shared witness, the administrator must meet several requirements, one of which is that the ESXi hosts must have a minimum of 64 GBs of memory. This is because each host must have enough memory to run the VMs and also to support the vSAN metadata overhead. The other options are not requirements for a two-node vSAN cluster with a shared witness. The ESXi hosts do not need SSDs or NVMe for Virtual Flash File System, as they can use any supported storage devices for vSAN. The ESXi host’s controller cache and advanced features do not need to be disabled, as they can be used to improve performance and reliability. The ESXi host’s drives do not need to be configured in RAID 1, as vSAN uses its own software-defined RAID mechanism to provide Failures to Tolerate.

In a vSAN stretched cluster configuration, both data sites are active sites, but one site must be designated as the preferred site and the other site as the secondary or nonpreferred site. This configuration helps to ensure that data remains on a given site in case of a network partition between the sites. If the network connection between the two active sites is lost, vSAN continues operation with the preferred site, unless it is resyncing or has another issue. The site that leads to maximum data availability is the one that remains in operation. The other options are not relevant to this scenario.

The VMware solution that requires vSAN usage is VMware Cloud Foundation. VMware Cloud Foundation is an integrated software stack that bundles compute virtualization (VMware vSphere), storage virtualization (VMware vSAN), network virtualization (VMware NSX), and cloud management and monitoring (VMware vRealize Suite) into a single platform that can be deployed on premises or as a service within a public cloud. VMware Cloud Foundation relies on vSAN as the primary storage solution for its workload domains, which are logical pools of resources that can be used to run different types of workloads. The other options are not correct. VMware Horizon, VMware Telco Cloud Automation, and VMware Aria Automation are VMware solutions that do not require vSAN usage, although they can benefit from it. VMware Horizon is a platform that delivers virtual desktops and applications across a variety of devices and locations, and it can use any supported storage solution, including vSAN. VMware Telco Cloud Automation is a cloud-native orchestration and automation platform that enables communication service providers to accelerate the deployment and lifecycle management of network functions and services across any network and cloud. It can use any supported storage solution, including vSAN. VMware Aria Automation is not a valid VMware solution name.
