3V0-12.26 exam questions

1. Question 1

   Multiple answer

   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.

2. Question 2

   Single answer

   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.

3. Question 3

   Multiple answer

   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.

   • 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.

   • C

5. Question 4

   Multiple answer

   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.

   [esxtop - CPU Panel Snippet]

   PCPU USED(%): 42.1 PCPUUTIL(%): 45.3

   ID GID NAME NWLD %USED %RUN %SYS %WAIT %VMWAIT %RDY %IDLE %CSTP %MLMTD

   3245 3245 Analytics-VM-1 50 145.20 146.10 1.10 4800.00 0.05 1.20 4600.00 18.50 0.00

   6789 6789 Web-Server-01 4 15.40 15.40 0.10 380.00 0.00 8.50 365.00 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.

6. Question 5

   Single answer

   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.

   Reveal answer

   Correct answer

   • 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.
