At ValidExamDumps, we consistently monitor updates to the VMware 5V0-21.21 exam questions by VMware. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the VMware HCI Master Specialist exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by VMware in their VMware 5V0-21.21 exam. These outdated questions lead to customers failing their VMware HCI Master Specialist exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the VMware 5V0-21.21 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
An architect is working with vSAN and setting the fault domains to support FTT=1.
How many fault domains will be needed?
A company has deployed a 12-node (6-6-1) vSAN 7.0 stretched cluster for all production workloads.
The customer currently uses four different vSAN storage policies for running the workloads depending on the applications requirements:
* Policy 1 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Erasure Coding
* Policy 2 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Mirroring
* Policy 3 - Site Disaster Tolerance=None - Keep Data on Preferred, FTT=Mirroring
* Policy 4 - Site Disaster Tolerance=None - Keep Data on Non-Preferred, FTT=Mirroring
During the setup of the vSAN stretched cluster, the following VM/Host Rules were created:
* Preferred Site - Preferred Site workloads should run on DC1 hosts.
* Secondary Site - Secondary Site workloads should run on DC2 hosts.
Which two activities should the administrator complete to ensure that there is no impact to production services during the maintenance window in the Preferred Site? (Choose two.)
A customer is planning to deploy a vSAN cluster to host their in-house distributed ERP system. The hardware specifications for their server nodes include:
* 2 x Intel Xeon CPU E5-2697 v3 @ 2.60GHz
* 1TB memory
Which boot device is supported for the vSAN ESXi nodes for this customer?
If the memory of the ESXi host has 512 GB of memory or less, you can boot the host from a USB, SD, or SATADOM device. If the memory of the ESXi host has more than 512 GB, consider the following guidelines. * You can boot the host from a SATADOM or disk device with a size of at least 16 GB. When you use a SATADOM device, use a single-level cell (SLC) device. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-planning.doc/GUID-B09CE19D-A3F6-408C-AE69-35F65CBE66E1.html
A 30-minute power maintenance window has been approved on Sunday. Due to a delay, the maintenance took 20 minutes longer to finish.
During this time, the vSAN administrator noticed that one of the clusters nodes was affected by a power shortage, as it was connected to an affected power source. The default vSAN storage policy has been applied.
What will be the status of the vSAN objects on the affected host immediately after it is recovered?
Default Storage Policy is FTT=1. https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.virtualsan.doc/GUID-C228168F-6807-4C2A-9D74-E584CAF49A2A.html
During a vSAN design workshop, an architect collected these customer requirements:
* Leverage vSAN storage policies with Erasure Coding.
* Enable Deduplication and Compression.
* Use the minimum number of hosts in the cluster.
* Maintain full storage policy compliance when two nodes are down.
Which vSAN cluster design meets the customer's requirements?
