Which two are requirements for Kubernetes cluster virtual machines when leveraging vSphere Cloud Native Storage (CNS)? (Choose two.)

• A.configure UEFI firmware
• B.set the disk.EnableUUID advanced setting to
• C.minimum of 4 vCPUs per node
• D.virtual machine hardware version 15 or higher
• E.Set the Disk Mode to Independent

A 4-node vSAN cluster has a single disk group per host. An administrator wants to increase the capacity of the vSAN datastore by adding a second disk group to each host in the cluster. The newer drives intended for the second disk group are certified and in compliance with VMware Compatibility Guide (VCG). However, the newer devices procured are of a different make and model than the existing disk group composition.
Considering the scenario, which statement is true?

• A.The Capacity Tier devices need to be the same make and model as other disk groups.
• B.The Cache Tier devices need to be the same make and model as other disk groups.
• C.This configuration is supported, however performance may vary across disk groups.
• D.This configuration is supported, however a separate controller is mandatory for each disk vendor.

An All-Flash vSAN cluster has 4-nodes with this disk group composition on each host:
* 1 x 800 GB SAS SSD
* 6 x 3.84 TB SATA SSD
An administrator observes that in an All-Flash cluster, the Write
Buffer Free Percentage is consistently low. As a result there is increased latency experienced by the workloads.
Which remediation steps will resolve this issue?

• A.Add a second cache device to the same disk group to increase the caching size.
• B.Modify advanced vSAN configuration parameters to utilize the complete 800 GB for caching.
• C.Replace the existing cache device with a larger cache device.
• D.Add a second disk group with a new cache device and distribute the capacity disks equally.

Which storage policy can be assigned to virtual machines In a 5-node, all flash vSAN cluster, to provide the highest level of redundancy?

• A.2 failures - RAID-1 (Mirroring)
• B.3 failures - RAID-1 (Mirroring)
• C.1 failure - RAID-5 (Erasure Coding)
• D.2 failures - RAID-6 (Erasure Coding)

An architect is designing network high availability for a new vSAN Cluster.
Which is a supported configuration for this design?
D18912E1457D5D1DDCBD40AB3BF70D5D

• A.Configure multicast to use two separate network interfaces for vSAN traffic.
• B.Create multiple VMkernel adapters on the same subnet for vSAN.
• C.Create an additional TCP/IP stack within the cluster and specify vSAN type.
• D.Use LACP on the distributed switch with a route based on IP hash algorithm.
