Question 36

A VI Admin completes an automated vSAN ReadyNode firmware upgrade using vLCM. After the ESXi hosts reboot, multiple Virtual Machines become unresponsive, and vSAN Skyline Health turns Red.
```
[UI - Skyline Health > Hardware Compatibility]
Issue: "vSAN I/O Controller Driver and Firmware are not matched"
Host: esx-08
Controller: Avago LSI 3108
Running Firmware: 4.680.00 (Upgraded)
Running Driver: 7.712.00 (Legacy)
```
What operational failure caused this post-upgrade storage outage, and what is the standard remediation? (Select all that apply.)
  • Question 37

    An L3 Support Engineer is called into a war room. A vSAN ESA Stretched Cluster (Site A and Site B, with Witness at Site C) has suffered a complex cascade failure.
    Current State:
    1. Site B suffered a total power loss.
    2. Simultaneously, the Witness Appliance network link at Site C was severed.
    3. Site A remains fully operational with no hardware faults.
    The VMs originally running on Site B are unreachable. The VMs originally running on Site A are frozen.
    The Storage Policy configuration is shown below:
    ```
    # Stretched Cluster Policy
    [Site-Disaster-Tolerance]
    Rule = "Dual site mirroring (stretched cluster)"
    [Failures-to-Tolerate]
    Rule = "1 failure - RAID-5 (Erasure Coding) [Local]"
    [Advanced-Rule]
    ForceProvisioning = 0
    ```
    Based on the integration of Object Health states and Stretched Cluster topology, why are the VMs on Site A frozen, and what is the exact status of their storage objects? (Select all that apply.)
  • Question 38

    Select the storage capabilities supported for use with persistent volumes in the VMware Kubernetes Service (VKS) in VMware Cloud Foundation (VCF).
    Drag and drop the five supported capabilities from the vSphere Storage Capabilities list on the left and place them into the Supported Storage Capabilities list on the right in any order. (Choose five.)

    Question 39

    An administrator notices alerts triggering IOPS and Disk Throughput storage performance problems in the Fibre Channel datastore in a VMware Cloud Foundation (VCF) Workload Domain.
    What can the administrator review to identify which Virtual Machines (VMs) may be experiencing storage IOPS and disk throughput performance issues?
  • Question 40

    A VI Admin is diagnosing a "Component Limit Exceeded" alert on a vSAN OSA cluster.
    The cluster capacity is at 50%, but several ESXi hosts have hit their 9,000 maximum component count.
    The admin queries the component tree for a large data warehouse VM.
    ```
    [RVC Output: vsan.obj_status_report ~cluster]
    Object: SQL-DW-Data (4.0 TB)
    Policy: FTT=1 (RAID-1), Stripe Width = 12
    Total Object Component Count: 28 components
    - Replica 1: 12 Stripe chunks + 2 Concatenation chunks (Size > 255GB)
    - Replica 2: 12 Stripe chunks + 2 Concatenation chunks
    - Witness: 0 (No tie-breaker currently mapped)
    ```
    Based on the RVC output and vSAN mechanics, which TWO factors directly caused this single VMDK to consume 28 metadata components? (Choose 2.)
