NO.42 During yesterday’s business hours, a cache drive failed on one of the vSAN OSA nodes. The administrator reached out to the manufacturer and received a replacement drive the following day. When the drive failed, vSAN started a resync to ensure the health of the data, and all objects are showing a healthy and compliant state. The vSAN administrator needs to replace the failed cache drive.
Which set of steps should the vSAN administrator take?

Physically replace the failed cache device, and vSAN will automatically create a new disk group. Then, remove the disk group with the failed device.

Place the disk group into maintenance mode, and select Full Data Migration. Then, physically replace the failed cache device. Afterwards. vSAN will rebuild the disk group automatically.
C Remove the existing vSAN disk group and physically replace thedevice. Thencheck to verify that the ESXi host automatically detects the new device Afterwardsmanually recreate the Disk Group

Physically replace the failed cache device, and vSAN will automatically allocate the storage. Then, rebalance the cache layer.

NO.45 A customer wishes to host a new range of applications with high-performance requirements, specifically, low latency. The current vSAN platform is based on ReadyNode hardware and uses a vSAN 7.0 U2 hybrid topology configuration.
Which would satisfy the customer’s requirement?

Deploy the application on a new cluster with vSAN 8.0 ESA using a new hardware design

Deploy the new applications on the existing cluster with a RAID-6 VM storage policy and an additional stripe width of 4

Deploy the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration

Perform an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA

Explanation
Deploying the application on a new cluster with vSAN 8.0 ESA using a new hardware design is the correct answer because it will satisfy the customer’s requirement for low latency. vSAN 8.0 ESA is a new architecture that uses a storage pool configuration where all disks are treated as capacity disks and use a new algorithm to distribute data across them. This improves the I/O flow, reduces the write amplification, and eliminates the cache tier bottleneck. Using a new hardware design with all-flash disks or NVMe disks will further enhance the performance and latency of the application, as these disks have faster read and write speeds than hybrid disks. Deploying the new applications on the existing cluster with a RAID-6 VM storage policy and an additionalstripe width of 4, deploying the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration, and performing an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA are not valid or optimal solutions for this scenario. Deploying the new applications on the existing cluster with a RAID-6 VM storage policy and an additional stripe width of 4 will increase the resiliency and availability of the data, but it will also increase the network traffic, disk space consumption, and parity calculation overhead, which will negatively affect the latency and performance of the application. Deploying the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration will not improve the latency significantly, as vSAN 8.0 OSA still uses the same disk group configuration as vSAN 7.0 U2 OSA, where one disk is designated as a cache disk and the rest are capacity disks. The cache disk can still become a bottleneck for high-performance applications, especially if it is not an SSD or NVMe disk. Performing an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA is not possible, as vSAN ESA requires a different hardware design than vSAN OSA. The existing disk groups need to be deleted and all disks need to be erased before switching to vSAN ESA. References:

Create a new disk group with a single capacity device and then migrate the existing capacity devices

Add the new capacity device to the disk group and vSAN will automatically rebalance

Put the entire ESXi host in maintenance mode, evacuate all data, then add the new capacity device

Put the disk group in maintenance mode, evacuate all data, then add the new capacity device

NO.55 A customer has deployed a new vSAN Cluster with the following configuration:
* 6 x vSAN ReadyNodes

* 12 TB Raw Storage
* vSAN 8 is deployed with ESA.

NO.56 An existing vSAN OSA cluster has this specification:
Four ESXi hosts with all flash configuration
Each with two disk groups
Each disk group with one cache device and four capacity devices
There are five more device slots available per host
The CTO would like to provision new applications, and these will need more capacity and performance.
Which two methods should be used by the vSAN administrator to meet this goal with the least amount of impact? (Choose two.)

Replacing all capacity devices with a similar larger device

Replacing all cache devices with a larger device

Adding one more disk group per host with the same configuration

Adding faster cache devices

Adding an ESXi host with identical device configuration

Explanation
Adding one more disk group per host with the same configuration and adding an ESXi host with identical device configuration are the two methods that the vSAN administrator should use to meet the goal of increasing capacity and performance with the least amount of impact. Adding one more disk group per host will increase the raw storage capacity by 20% and also improve the performance by distributing the I/O load across more cache devices and disk groups. Adding an ESXi host with identical device configuration will increase the raw storage capacity by 25% and also improve the performance by adding more compute and network resources to the cluster. Both methods can be done without disrupting any ongoing operations or requiring any data evacuation or resynchronization.
The other options are incorrect for the following reasons:
Replacing all capacity devices with a similar larger device is incorrect because it will not increase the performance and will have a significant impact on the cluster. Replacing the capacity devices requires deleting the disk groups, which will erase all data on them and trigger a resynchronization of the affected objects. This can be disruptive and time-consuming, and also introduce additional network and disk traffic.
Replacing all cache devices with a larger device is incorrect because it will not increase the capacity and will have a significant impact on the cluster. Replacing the cache devices also requires deleting the disk groups, which will have the same drawbacks as replacing the capacity devices. Moreover, increasing the cache size may not improve the performance significantly, as vSAN OSA uses afixed cache ratio of
70% for write buffer and 30% for read cache, regardless of the cache device size.
Adding faster cache devices is incorrect because it will not increase the capacity and will have a significant impact on the cluster. Adding faster cache devices also requires deleting the disk groups, which will have the same drawbacks as replacing the cache devices. Furthermore, adding faster cache devices may not improve the performance significantly, as vSAN OSA uses a fixed cache ratio of 70% for write buffer and 30% for read cache, regardless of the cache device speed.
