S2112500 IBM Cloud for VMware v1 Specialty Practice Exam
Exam Number: 4309 | Last updated April 17, 2026 | 471+ questions across 5 vendor-aligned objectives
Candidates who pursue the IBM Cloud for VMware v1 Specialty typically design and operate VMware workloads hosted in IBM Cloud. The exam validates your ability to choose between VMware Cloud Foundation for Classic and VMware as a Service patterns, integrate NSX networking, and handle day-two operations such as expansion, patching, and disaster recovery for VMware workloads on IBM Cloud.
Fronting the blueprint, Deployment Patterns and Architecture carries 26% weight, covering Classic VCF, VMware as a Service offerings, stretched clusters, and multi-site topologies. Storage and vSAN follows at 22%, covering vSAN sizing, stretched vSAN clusters, and the integration of IBM Cloud block and object storage with VMware workloads. Dominating the network section at 20%, NSX and Network Services covers NSX-T segments, edge gateways, distributed firewalls, and load balancing.
Beyond the core domains, Migration and Operations accounts for 18% and spans HCX, live migration, bulk migration, and day-two lifecycle tasks such as vCenter and ESXi patching. Disaster Recovery and Business Continuity represents 14% of the exam and spans Zerto, VMware Cloud DR, and cross-region replication. Scenario questions often pair a migration choice with a DR requirement, so expect to reason about both at once.

10 of 471+ questions
Question #1 - Deployment Patterns and Architecture
A customer wants to minimize the operational work their team does on vCenter, ESXi, and NSX lifecycle patching, and is willing to trade some administrative control for this.
Which IBM Cloud VMware offering best matches?
A) VMware Cloud Foundation for Classic with customer-managed patching
B) A self-built vSphere cluster on bare-metal servers with no IBM involvement
C) VMware as a Service, where IBM manages the lifecycle of core VMware components
D) Only use VMs on IBM Cloud VPC, with no VMware at all
Show solution
Correct answers: C – Explanation:
VMware as a Service has IBM manage core VMware component lifecycles, matching the customer’s preference to trade administrative control for reduced operational work. Classic VCF leaves patching with the customer. Self-built bare-metal maximizes operational work. VPC-only removes VMware entirely and does not fit the scenario. Source: Check Source
Question #2 - Migration and Operations
A customer must move several dozen virtual machines from on-premises vSphere to IBM Cloud VMware with minimal downtime per VM and a limited maintenance window for cutover.
Which HCX migration type is best?
A) HCX Cold Migration
B) HCX Bulk Migration with scheduled switchover
C) HCX Replication Assisted vMotion (RAV)
D) A manual OVA export and import
Show solution
Correct answers: C – Explanation:
Replication Assisted vMotion combines ongoing replication with a short final vMotion cutover, minimizing per-VM downtime and fitting a short maintenance window. Cold migration requires the VM to be powered off for the duration. Bulk migration is scheduled and can cause longer per-VM downtime. OVA export/import is entirely manual and slow.

Question #3 - NSX and Network Services
A security architect wants to enforce east-west microsegmentation between application tiers inside a VMware cluster, regardless of VLAN or subnet placement.
Which NSX capability satisfies the requirement?
A) Public internet segmentation via IP allowlist
B) A single perimeter firewall at the edge
C) VLAN separation with no stateful firewalling
D) NSX Distributed Firewall with rules scoped by VM tag or security group
Show solution
Correct answers: D – Explanation:
The NSX Distributed Firewall enforces stateful rules at the vNIC, scoped by tags or security groups, which is exactly how microsegmentation works inside a cluster. A perimeter firewall does not inspect east-west traffic inside the cluster. VLANs alone lack stateful firewalling. Public-internet allowlists do not apply to east-west traffic. Source: Check Source
Question #4 - Storage and vSAN
A storage architect must size vSAN capacity for a three-node cluster with RAID-1 mirroring, factoring in slack space and the organization’s plan to host 30 TB of useful data.
Which sizing approach is defensible?
A) Provision exactly 30 TB of raw capacity
B) Provision raw capacity to account for RAID-1 (roughly 2x), slack space (commonly ~25-30%), and growth
C) Provision 30 TB and rely on deduplication to cover mirroring overhead
D) Use RAID-0 to avoid mirroring overhead entirely
Show solution
Correct answers: B – Explanation:
Correct vSAN sizing multiplies useful capacity by the RAID factor and adds slack space and growth headroom, which aligns with VMware’s published guidance. 1:1 sizing ignores mirroring and slack. Deduplication varies by data and does not eliminate the need for RAID-1 overhead. RAID-0 removes the mirroring but also removes all data resilience. Source: Check Source
Question #5 - Deployment Patterns and Architecture
A customer with facilities in two IBM Cloud data centers in the same region asks for an active-active VMware design that tolerates the loss of one data center with zero data loss.
Which topology is correct?
A) Two independent clusters with async replication only
B) A stretched VMware Cloud Foundation cluster across the two data centers with vSAN stretched cluster
C) Two clusters with nightly backups
D) A single cluster in one data center with hot spare hardware in the other
Show solution
Correct answers: B – Explanation:
A stretched VCF cluster with vSAN stretched cluster across both data centers provides active-active with synchronous mirroring, which is the only pattern here that achieves zero data loss on a data-center failure. Async replication implies nonzero RPO. Nightly backups have RPOs measured in hours. A single cluster with hot spare hardware has no live data in the other site. Source: Check Source
Question #6 - Disaster Recovery and Business Continuity
A CIO wants DR for a VMware estate with an RTO of under 15 minutes and RPO of under 30 seconds across IBM Cloud regions, with continuous replication at the hypervisor layer.
Which solution most directly fits?
A) No DR; accept the risk
B) Weekly VM exports copied to the DR region
C) Manual rebuild of VMs at the DR region after a disaster
D) Zerto continuous replication between source and DR IBM Cloud regions
Show solution
Correct answers: D – Explanation:
Zerto’s continuous data protection replicates at the hypervisor layer with RPOs typically in seconds and rapid orchestrated failover, directly matching the RTO and RPO targets. Weekly exports produce RPOs of days. Manual rebuilds produce RTOs measured in hours or longer. Accepting the risk does not meet the requirement. Source: Check Source
Question #7 - Migration and Operations
After go-live, an ESXi host in a Classic VCF cluster shows a failing hardware component. The on-call engineer must identify the responsible party for replacing the hardware.
Which answer is correct?
A) The customer must physically replace the hardware themselves
B) IBM owns physical hardware replacement for Classic VCF infrastructure
C) The customer must ship a replacement to IBM
D) The cluster must be redeployed from scratch
Show solution
Correct answers: B – Explanation:
IBM is responsible for the physical infrastructure in Classic VCF deployments, including hardware replacement. Customers do not visit IBM data centers or ship hardware. Redeploying the cluster is neither necessary nor appropriate for a single failing component. Source: Check Source
Question #8 - NSX and Network Services
A workload in an IBM Cloud VMware environment needs to publish a web service to the public internet, terminate TLS at the perimeter, and distribute traffic across multiple backend VMs.
Which NSX-T capability is most appropriate?
A) NSX Tier-0 gateway with an edge load balancer providing TLS termination and VIP-based backend pools
B) A per-VM static NAT to the public internet
C) A public-IP alias on every backend VM
D) A public cloud function outside the VMware environment
Show solution
Correct answers: A – Explanation:
An NSX-T edge load balancer on the Tier-0 gateway terminates TLS and distributes to backend pools, which is the idiomatic way to publish a web service from an NSX-managed environment. Per-VM NAT does not load-balance. Public-IP aliases on every VM expose each backend and still need a load balancer. Cloud functions are a different architecture and do not serve VMware-resident backends directly. Source: Check Source
Question #9 - Storage and vSAN
A capacity planner wants to use IBM Cloud Object Storage as a low-cost archive tier for cold VM data written from a VMware workload.
Which integration pattern is correct?
A) Back up cold VMs to IBM Cloud Object Storage via a Veeam or similar VMware-aware backup tool
B) Mount IBM Cloud Object Storage directly as a vSAN disk
C) Use Object Storage as the primary VMFS datastore
D) Ignore Object Storage and keep everything on vSAN forever
Show solution
Correct answers: A – Explanation:
Backing up cold VMs through a VMware-aware tool that targets Cloud Object Storage is the supported archive pattern. Object Storage is not a block target and cannot be a vSAN disk. It is also not a supported primary VMFS datastore. Keeping everything on vSAN defeats the goal of a lower-cost archive tier. Source: Check Source
Question #10 - Deployment Patterns and Architecture
A customer asks which party manages vCenter patching in the newer VMware as a Service offering versus Classic VCF.
Which statement is correct?
A) IBM patches vCenter in VMware as a Service; the customer patches vCenter in Classic VCF
B) The customer patches vCenter in both offerings
C) IBM patches vCenter in both offerings
D) Neither IBM nor the customer patches vCenter; VMware does it through a public SaaS
Show solution
Correct answers: A – Explanation:
The split between IBM-managed VMware as a Service and customer-managed Classic VCF is the key distinction, and it matches how vCenter patching responsibility is assigned. Customer-in-both and IBM-in-both both misrepresent one of the offerings. The public-SaaS answer is not how IBM Cloud VMware is delivered. Source: Check Source
