An administrator creates a cluster by joining a Medium sized VMware Cloud Foundation (VCF) Operations for Logs node to an existing Medium sized single-node deployment.
The secondary node of the cluster fails, degrading the functionality of VCF Operations for Logs.
What action should the administrator take to create a healthy active cluster?

Correct Answer:C
In VMware Cloud Foundation (VCF)Operations for Logs, clusters require aminimum of three healthy nodesto function in a fully active and resilient state. When a cluster is deployed with only two nodes (primary
+ one secondary), the environment does not meet the minimum recommended requirement. If the secondary node fails, the cluster becomes degraded and functionality is reduced.
The correct remediation is:
Rebuild the failed secondary nodeso that the cluster can return to a healthy state.
After rebuilding, the node must be rejoined to the primary using theManagement # Clusterworkflow (secure token, IP/hostname of primary, etc.).
Why not the other options?
A. Scale up to Extra Large##Scaling up affects resource capacity (vCPU, RAM, disk) but does not solve the problem of missing nodes.
B. Scale up to Large##Same reason as above, scaling up does not restore HA.
D. Rebuild the secondary and add an additional node##While adding more nodes is a best practice (since HA clusters require three nodes), theminimum action requiredto restore a healthy active cluster is torebuild the failed node. Adding more nodes is optional for increased resiliency.
Therefore, the immediate and verified answer is torebuild the failed secondary node.

An administrator is tasked to deploy a large-scale VDI environment on a VMware vSAN Original Storage Architecture (OSA) cluster.
Which vSAN feature is required to achieve maximum storage space reduction in this cluster?

Correct Answer:B
In avSAN Original Storage Architecture (OSA) cluster, the feature that provides themaximum storage space reductionisDeduplication and Compression.
Deduplication removes duplicate blocks across the cluster.
Compression further reduces the space used by unique blocks.
These are applied at thedisk group leveland are essential inVDI environmentswhere identical VM images consume space.
Why others are incorrect:
A. Disable Object Checksum# Only reduces CPU overhead, not storage space.
C. Object space reservation# Controls reserved capacity, not reduction.
D. Compression only# Reduces space, but less than Deduplication + Compression combined. References:

An administrator is tasked with creating dashboards to track system performance metrics for both the IT department and executive leadership. The requirements for this task are:
The IT team needs detailed, technical metrics across all of the infrastructure components in the environment.
The executives need high-level summaries that highlight Key Performance Indicators (KPIs) across the environment in a single dashboard.
The executives need to access the dashboard via a shared URL.
The dashboards must be capable of being shared, and always display the latest data collected when the link is used.
What two steps should the administrator perform to meet these requirements? (Choose two.)

Correct Answer:AB
To satisfy both IT and executive requirements:
IT team# Needsdetailed technical metrics, which are available throughOut-of-the-Box dashboards in VCF Operations. (A)
Executives# Need acustom KPI-focused dashboard, with summaries and high-level visibility. This can be shared via aURL linkthat always shows the latest data. (B)
Why others are incorrect:
C. Custom dashboard in VCF Operations for Logs# Logs are not KPI-focused performance metrics.
D. Out-of-the-Box dashboards in VCF Automation# VCF Automation is not designed for KPI reporting. References:

An administrator is tasked to implement a new iSCSI storage for a new cluster. The following information was provided to the administrator:
iSCSI storage controller IPs are all in the same subnet.
Multipathing should be used.
Storage supports Asymmetric Logical Unit Access (ALUA).
Should be configured for high performance.
Which are the four required steps to configure this on an ESX host? (Choose four.)

Correct Answer:BEFG
ForiSCSI multipathing with ALUAandhigh performancein ESXi:
1 vSwitch with 2 Uplinks# Standard design for redundancy and multipathing. (B)
Add iSCSI software adapter# Required to connect to storage. (E)
Configure two bound VMkernel ports# Ensures multipathing (one per uplink). (G)
Set PSP to Round Robin (RR)# Optimizes I/O balancing across multiple paths. (F)
Other options:
A. 2 vSwitches with 1 Uplink each# Not recommended, complicates multipathing.
C. NVMe over TCP# Not relevant, storage is iSCSI.
D. MRU policy# Legacy, not high performance.
H. Unbound VMkernel ports# Used for software iSCSI port binding, but "bound" VMkernel ports are required for multipathing.

An administrator needs to enable the enhanced capabilities of Storage Operations for vSAN 9.0 in VMware Cloud Foundation (VCF) Operations.
What three prerequisite steps must be completed in order to enable the advanced Diagnostic Troubleshooting, Benchmarking and Optimizing? (Choose three.)

Correct Answer:BCE
To enableenhanced capabilities of Storage Operations for vSAN 9.0 in VCF Operations(Diagnostic Troubleshooting, Benchmarking, and Optimizing), administrators must complete several prerequisites that ensure vSAN health, performance, and permissions are properly set up.
Enable and start the vSAN Performance service in the target vCenter (B):
The vSAN Performance Service must be enabled for cluster-level monitoring.
This provides the telemetry data needed for diagnostic and benchmarking capabilities in VCF Operations.
Without enabling this service, no performance metrics can be collected.
Configure a vSAN account for the vCenter Integration Instance (C):
A dedicated vSAN service account must be configured so that VCF Operations can communicate with vCenter for vSAN data collection.
This ensures secure and role-specific access for monitoring operations.
Assign the credentials configured in the vCenter Integration instance to have access to vSAN objects (E):
The credentials used in the vCenter integration must have the required privileges to access vSAN objects (such as datastore, cluster objects, and health checks).
This ensures that VCF Operations can run diagnostics, benchmarking, and optimization functions without permission errors.
Why the other options are incorrect:
A. No configuration required, Run New Diagnostics is enabled automatically:❌Incorrect. Configuration is required before these advanced features can be enabled.
D. Assign the VCF Operations Service Account administrative rights to vSAN Objects:❌Too broad and not a best practice. Instead, specific rights via the vCenter integration account (option E) are recommended.
F. Open port 5989 on each VCF Operations node on which the vSAN adapter exists:❌Not required for enabling vSAN advanced diagnostics in VCF 9.0. vSAN operations rely on vCenter connectivity, not direct port 5989.
