3. QUESTION: 4 A 12-node vSAN cluster has been deployed across three server racks in a data center. There are four nodes in each server rack. A vSAN fault domain has been configured for each server rack for a total of three fault domains. All virtual machines in the cluster have the vSAN default storage policy assigned to them. This policy has not been modified. vSphere HA is enabled for the cluster. One of the server racks loses power. How does this affect virtual machines running on this cluster? A. Since there are four nodes in each server rack, erasure coding is used to rebuild data that was lost due to the server rack power failure. vSphere HA monitors the rebuild process and powers on all affected virtual machines after the rebuild process is complete. B. Virtual machine data in the failed server rack is rebuilt immediately using parity information. vSphere HA powers off and restarts all of the virtual machines to rebalance storage utilization across the cluster. C. All virtual machine data remains accessible. Virtual machines running on nodes in the failed server rack are restarted on nodes in the other two server racks. Virtual machines in the other two server racks continue to run. D. Virtual machines running on nodes in the failed server rack remain offline for 60 minutes. Virtual machines in the other two server racks continue to run and are marked "Degraded". Answer: C QUESTION: 5 Which statement is true about the deduplication and compression feature in vSAN? A. Redundant blocks across multiple disk groups are NOT deduplicated. B. Compression removes redundant data blocks, whereas deduplication removes additional redundant data within each data block. C. Compression occurs as data is moved from the capacity tier to the cache tier. D. Deduplication and compression are enabled by default when the vSAN cluster is created.

6. vSphere/5.5/com.vmware.vsphere.storage.doc/GUID-ACC10393- 47F6-4 QUESTION: 12 An administrator is designing a vSAN cluster for a number of new workloads. The design calls for the use of erasure coding with RAID 5. Which statement is true about what is needed to meet the needs of this scenario? A. vSAN Standard licensing is sufficient B. vSAN Enterprise licensing is required C. An all-flash configuration is required. D. Six nodes are required at a minimum. Answer: C Explanation RAID 5 or RAID 6 erasure coding is available only on all-flash disk groups. References: https://docs.vmware.com/en/VMware- vSphere/6.5/com.vmware.vsphere.virtualsan.doc/GUID-6D818555-8DE8 QUESTION: 13 What is the procedure for presenting an iSCSI LUN as a target for a VMFS datastore? A. Ensure that the ANY_INITIATOR is listed in the Allowed Initiators tab in vSAN iSCSI Target configuration. B. Add as a traditional VMFS datastore and connect using the vSAN iSCSI Target IQN. C. The use of the vSAN iSCSI Target for providing storage directly to vSphere is not currently supported. D. Use iSCSI vCenter Server Plugin on the target ESXi host.

8. B. 3 TB C. 6 TB D. 4 TB Answer: C Explanation To determine the raw capacity of a Virtual SAN datastore, multiply the total number of disk groups in the cluster by the size of the capacity devices in those disk groups, and subtract the overhead required by the Virtual SAN on-disk format.

Choose the vSAN version you want to deploy, pick a ReadyNode profile based on your specific needs, select your preferred server vendor, and then pick one of the available models. Note: vSAN ReadyNode are x86 servers, available from all the leading server vendors, that have been pre-configured, tested and certified for VMware Hyper-Converged Infrastructure Software. Each ReadyNode is optimally configured for vSAN with the required amount of CPU, memory, network, I/O controllers and storage (SSDs, HDDs or flash devices). Some ReadyNode are available with additional options aimed at simplifying purchasing, deployment, and support. These options are only available for select server vendors and ReadyNode models: QUESTION: 17 Which two vSAN configurations require the use of a witness appliance? (Choose two.)
