1.An Enterprise IT Strategist is designing a cyber recovery strategy for a healthcare organization. They
must configure the VMware Live Cyber Recovery snapshot retention policies to align with business
requirements.
Cyber Recovery Strategy Overview
Regulatory Requirement: 6 months immutable backups
Monthly Budget Cap: $50,000 USD
Workload Churn: 500GB daily delta (Patient Systems)
Assumed Threat Dwell Time: 90 Days
Which THREE design decisions provide the most appropriate trade-off to meet these constraints while
providing a robust ransomware recovery posture? (Select all that apply.)
A. Exclude non-critical application logs and temporary development databases from the Live Recovery
protection groups to reduce the cloud storage footprint.
B. Utilize the Live Recovery Cloud Connector to replicate the active vSAN ESA storage policies directly to
the public cloud to maintain parity.
C. Configure a high-frequency hourly snapshot schedule with a strict 6-month retention lock for all patient
data systems to ensure the most granular recovery points possible.
D. Implement a tiered retention policy: retain daily snapshots for 14 days, weekly snapshots for 3 months,
and monthly snapshots up to 6 months.
E. Leverage VMware Live Cyber Recovery's inherent delta-based (incremental-forever) snapshot
architecture to minimize the storage impact of the high daily churn.
Answer: A, D, E
2.A VCF Solutions Architect is documenting the disaster recovery procedures for the Management
Domain. A catastrophic storage array failure destroys all three nodes of the NSX Manager cluster, though
the vCenter Server and SDDC Manager survived on a separate datastore.
The architect must execute a restoration from the external SFTP backup server.
How must the architect structure the NSX Manager cluster recovery process?
[Hardware_Symptom_Report]
- NSX Node 1: Unrecoverable VMFS corruption.
- NSX Node 2: Unrecoverable VMFS corruption.
- NSX Node 3: Unrecoverable VMFS corruption.
A. Deploy a single new NSX Manager node, restore the cluster database from the SFTP backup to this
single node, and then scale out the cluster by joining two additional fresh nodes.
B. Restore the three original NSX Manager virtual machines from hypervisor-level snapshot backups and
execute the nsxcli cluster re-init command to force a new quorum.
C. Deploy three fresh NSX Manager virtual appliances simultaneously via the SDDC Manager UI and
point all three to the SFTP server to trigger a parallel distributed restore.
D. Deploy a single NSX Manager node, manually recreate the Tier-0 gateway, and then initiate an "Import
Configuration" task from the SDDC Manager to synchronize the remaining state.
Answer: A
3.A Cloud Operations Engineer is troubleshooting access issues following the successful configuration of
Identity Provider (IdP) Federation (using Okta via OIDC) for the vCenter Server.

3 / 5
- User A (Okta) successfully logs in via web browser, but has 0 permissions.
- User B attempts an API script execution and fails to authenticate.
- Administrator cannot run SDDC Manager host commissioning workflows.
Which THREE statements accurately describe the underlying token handling, RBAC mapping, and
troubleshooting realities of vCenter Identity Federation? (Select all that apply.)
A. Disabling the native vsphere.local domain is a required security step once an external Identity Provider
is successfully federated and configured.
B. If the LDAPS certificate on the Active Directory server is renewed and changes, vCenter SSO will
automatically accept the new certificate via the 'Trust on First Use' (TOFU) protocol without administrative
intervention.
C. If the external Identity Provider (e.g., Okta) becomes unreachable, administrators can still authenticate
using the local administrator@vsphere.local account, as it is evaluated natively by vCenter SSO.
D. SDDC Manager workflows (like host commissioning) will fail if the internal vCenter SSO STS (Security
Token Service) certificate is expired, as SDDC Manager relies heavily on internal STS tokens for API
authentication, regardless of the external IdP.
E. When using Identity Federation (OIDC/SAML), the external IdP handles the authentication challenge,
but vCenter Server still internally maps the returned user claims (groups) to local vSphere RBAC
permissions; User A likely lacks a vSphere role mapping.
Answer: C, D, E
4.An NSX Network Engineer is reviewing the automated configurations applied by SDDC Manager
immediately after the successful completion of a "Stretch Cluster" workflow. The cluster was stretched
from Site A to Site B.
Which TWO specific configurations does SDDC Manager automatically apply to the vSphere/vCenter
environment to ensure proper virtual machine placement and fault domain isolation? (Choose 2.)
A. It creates vSphere DRS Host Groups (one for Site A hosts, one for Site B hosts) and corresponding
"Should Run" VM/Host affinity rules to enforce localized compute execution.
B. It configures a dedicated vSphere Replication appliance on the Site B hosts to asynchronously mirror
the virtual machine RAM state back to Site
A. C. It creates two active vSAN Fault Domains ("Preferred" for Site A and "Secondary" for Site B) and
places the respective ESXi hosts into them.
D. It automatically deletes the localized NSX Tier-1 gateways and replaces them with a singular Global
Tier-0 gateway spanning both sites.
E. It automatically alters the NSX Distributed Firewall "Default Deny" rule to allow synchronous storage
traffic between the two vSAN Fault Domains.
Answer: A, C
5.A Cloud Operations Engineer is provisioning a storage policy for a new set of mission-critical databases
within a 16-node vSAN cluster. The ESXi hosts are physically distributed evenly across 4 racks (4 hosts
per rack). The business requirement mandates that the databases must remain accessible even if an
entire physical rack loses power.
Review the proposed vSAN storage policy configuration:

4 / 5
Failures to tolerate (FTT): 1 failure - RAID-1 (Mirroring)
Number of disk stripes per object: 1
Flash Read Cache reservation: 0%
Force provisioning: False
Assuming the 4 physical racks are correctly configured as 4 distinct vSAN fault domains, what is the
architectural outcome of applying this policy to the databases?
A. The database becomes inaccessible during a rack failure because, in vSAN storage policies, RAID-1
mirroring with FTT=1 does not leverage explicit fault domain awareness; this capability activates only
when configured with FTT=2 or higher.
B. The database survives a single rack failure because vSAN places two replicas and a witness
component across three distinct fault domains.
C. The policy guarantees survival against two simultaneous rack failures due to the cluster's size of 16
hosts, which significantly exceeds the minimum host requirement of 3 for an FTT=1 configuration.
D. The policy application fails because an FTT=1 configuration with explicit fault domains in vSAN
requires a minimum of 5 fault domains to properly place the witness component and maintain quorum.
Answer: B
6.What is the primary architectural requirement when deploying VMware Private AI Foundation with
NVIDIA on VMware Cloud Foundation (VCF)?
A. It requires HCX network extension to stretch Layer 2 networks to NVIDIA's public cloud endpoints.
B. It mandates the use of VCF Fleet architecture to separate the control plane from GPU workloads.
C. It depends on Live Recovery to replicate deep learning models across multipleisolated recovery
environments.
D. It utilizes vSphere features like vGPU profiles to partition physical GPUs for concurrent workload
access.
Answer: D
7.An Infrastructure Capacity Planner is architecting the placement of NSX Advanced Load Balancer (Avi)
components within a standard VMware Cloud Foundation architecture.
The environment consists of one Management Domain and two isolated Workload Domains (WLD-01 and
WLD-02).
Which THREE architectural principles govern the correct placement, integration, and scaling of the Avi
Controllers and Service Engines across these distinct domains? (Select all that apply.)
A. To load balance traffic in WLD-01 and WLD-02, the central Avi Controller cluster must be integrated via
two distinct "NSX-T Cloud" connectors, mapping to each Workload Domain's respective vCenter and NSX
Manager.
B. Service Engine (SE) VMs must be deployed physically into the Management Domain cluster to ensure
their management interfaces reside on the same broadcast domain as the Avi Controllers.
C. The 3-node Avi Controller cluster must be deployed centrally within the Management Domain vCenter,
alongside SDDC Manager and the NSX Manager clusters.
D. Service Engine (SE) VMs are deployed directly into the vSphere clusters of the specific Workload
Domains (WLD-01 and WLD-02) where the tenant virtual machines they are load balancing reside.
E. A dedicated 3-node Avi Controller cluster must be deployed inside every single Workload Domain;
centralized controller management across multiple domains is unsupported in VCF.

8.A VCF Platform Administrator receives an urgent escalation regarding a newly deployed "Monster VM"
(configured with 48 vCPUs) used for data analytics. The users report that the application is running
significantly slower than it did on its previous, less powerful hardware.
The administrator connects to the ESXi host via SSH and runs esxtop.

0.00 0.00
Based strictly on the provided esxtop metrics, which TWO architectural flaws are responsible for the
performance degradation of the analytics application? (Choose 2.)
A. The Analytics VM is drastically oversized for its actual workload, evidenced by the extremely high
Co-Stop (%CSTP) value combined with relatively low actual CPU usage.
B. The Analytics VM is actively thermal-throttling the physical CPUs, shown by the discrepancy between
the %USED and %RUN metrics.
C. The hypervisor is struggling to simultaneously schedule the massive 48 vCPU footprint across the
physical cores, forcing the VM's active threads to wait for synchronized execution.
D. The ESXi host is severely overcommitted, as indicated by the high CPU Ready (%RDY) time on the
Web-Server-01 workload, which is starving the Monster VM of resources.
Answer: A, C
9.A VCF Automation Developer is reviewing the conceptual differences between Distributed Routing and
Centralized Routing within an NSX environment to optimize a self-service blueprint. The blueprint needs
to deploy multi-tier applications with the lowest possible latency between tiers.
Which statement accurately differentiates Distributed Logical Routing from Centralized Routing in a
VMware Cloud Foundation (VCF) workload domain?
A. Distributed routing is exclusively used for north-south traffic egressing to the physical network, while
centralized routing handles all east-west communication between virtual machines on the same ESXi
host.
B. Distributed routing occurs within the ESXi hypervisor kernel for east-west traffic, while centralized
routing routes traffic through an NSX Edge node for stateful services or north-south egress.
C. Distributed routing relies on dedicated physical router appliances deployed outside the VCF rack, while
centralized routing uses virtual machines known as NSX Edge nodes for all packet forwarding.
D. Distributed routing requires all east-west traffic flows between virtual machines to exit the ESXi host
and traverse the physical Top-of-Rack switch infrastructure, whereas centralized routing processes all
packets entirely within the vSphere Distributed Switch (vDS) data plane.
Answer: B
