A vSAN ESA cluster experienced a host NVMe failure, causing several objects to become non-compliant.
Select the steps vSAN ESA follows to detect, evaluate and repair the non-compliant objects.
Drag and drop the four correct options from the Options list on the left and place them into the Required Options on the right in any order. (Choose four.)

정답:

Explanation:
ESA evaluates available capacity and fault domains to satisfy policy compliance.
vSAN detects the failure and marks affected objects as non-compliant.
Resync completes and objects transition to Compliant status.
New components are instantiated on eligible capacity devices, and resync begins.
A failed NVMe device in a vSAN ESA cluster is handled as a storage pool device failure. vSAN first detects the failure and marks affected objects as non-compliant when their assigned storage policy requirements are no longer satisfied. ESA then evaluates available capacity and fault domains to determine whether replacement components can be placed in a way that restores compliance. If sufficient placement resources exist, vSAN creates new components on eligible capacity devices and begins resynchronization. After the resync completes, the affected objects transition back to Compliant status. The Repair Delay Timer is primarily associated with absent components, such as a host or device that may return, and is not the required step for a permanent NVMe failure. The administrator does not have to manually trigger Repair Objects Immediately for the normal automatic repair process. A full cluster rebalance is separate from repair and is not performed before rebuilding missing or degraded components.

An administrator has been tasked with deploying vSAN Data Protection in a VMware Cloud Foundation (VCF) Workload Domain. The administrator deploys the VMware Live Recovery OVA and logs into the management interface to start the Configure Appliance process, but the appliance fails to register with vCenter.
What are two possible causes the administrator can check to resolve the issue? (Choose two.)

• A.The vCenter Server user account was created locally on the VCSA Photon OS level.
• B.The forward and reverse DNS resolution between the appliance and vCenter Server are not properly configured.
• C.The vSAN Data Protection appliance was deployed to a non-vSAN datastore.
• D.The appliance is using DHCP IP addresses for management.
• E.The vCenter Server user account used for registration does not have the required permissions.

An architect has been tasked with designing a vSAN OSA storage solution for a VMware Cloud Foundation (VCF) Private Cloud. The following requirements and constraints have been gathered from the client:
* 2 x 4 TB NVMe disks per host
* 6 hosts
* FTT=1/RAID-5 for all deployed Virtual Machines
* Expected Dedupe/Compression Ratio = 2 (100%)
* Reserve enough capacity to rebuild a host completely in case of a failure (Host Rebuild Reservation)
* Operational Reserve of 10%
* Expected Overhead for Filesystem, Object, etc. of 25%
What is the approximate expected usable capacity of the resulting array?

• A.32 TB
• B.48 TB
• C.40 TB
• D.24 TB

A storage architect has been called into a meeting with the accounting team who is trying to determine why
20% of their raw capacity is not available for consumption. Their vSAN cluster was created with the following characteristics:
* 2 x 2 TB NVMe disks in 6 hosts in their vSAN cluster.
* FTT=1, RAID-1 for the default policy.
* Host Rebuild Reserve not activated for this cluster.
Which two items should the Architect say accounts for most of the unusable capacity? (Choose two.)

• A.VM swap overhead
• B.RAID Overhead
• C.Operational Reserve (policy changes, rebalancing, data movement)
• D.Encryption overhead
• E.Host upgrade overhead

An administrator is monitoring a vSAN ESA backed workload domain that is dedicated for running AI inferencing. When the administrator navigates to the Storage Performance dashboard in VMware Cloud Foundation Operations, the performance dashboard shows:
* High backend write latency ( > 8 ms)
* Low read latency ( < 1 ms)
* Normal network throughput
* Disk Group Health = Green
Based on the readings above, what would be the explanation?

• A.A vSAN network congestion event on the vSAN TCP port 2233 is throttling mirror acknowledgements.
• B.The workload's small-block writes are compressed inline, lowering backend throughput and increasing cache misses.
• C.A wrongly sized read cache tier is throttling the write buffer, thus forcing the reads to trespass to the capacity tier.
• D.This is caused due to transient commit-queue delays, since the workload is exhibiting random-writes saturating ESA's write buffer.
