VMware 2V0-620 After Retirement: From vSphere 6 Foundations to VVF 9

VMware 2V0-620, the vSphere 6 Foundations exam, is a historical certification exam rather than a current target. VMware retired 2V0-620 on August 30, 2019. It was replaced at the time by a vSphere 6.7 foundations exam, and the certification program has changed substantially again since then under Broadcom.

That means an old “crack 2V0-620” study plan should not be refreshed as if candidates can still book the exam. The useful work is to preserve the durable vSphere concepts—virtual machines, ESXi hosts, vCenter, storage, networking, clusters, resource management, and operational troubleshooting—while mapping current certification decisions to the modern VMware vSphere Foundation and VMware Cloud Foundation portfolio.

Current VMware certifications are the right starting point for new candidates. Legacy material can still teach architecture, but exam codes and objectives must be checked against the current Broadcom catalog before they shape a preparation plan.

2V0-620 belongs to the vSphere 6 era

The vSphere 6 Foundations exam was designed to test entry-level administration knowledge for a platform generation launched more than a decade ago. Its scope included ESXi and vCenter fundamentals, virtual machines, virtual networking, storage, availability, resource management, and basic troubleshooting.

Those subjects remain recognizable because the core abstraction of server virtualization has not disappeared. Administrators still work with hosts, clusters, virtual switches, datastores, permissions, templates, snapshots, and monitoring. What changed is the product generation, feature set, certification program, and surrounding infrastructure strategy.

The correct historical label matters. A professional who sees 2V0-620 on an old transcript or training archive should understand what it represented, but a new learner should not confuse that history with a currently bookable exam.

The retirement path continued beyond the original successor

When VMware retired 2V0-620 in 2019, the immediate successor was associated with vSphere 6.7. That replacement is itself no longer the present certification destination. Repeating the 2019 migration advice in 2026 would therefore be another form of stale guidance.

Broadcom’s current VMware certification catalog centers on VMware Cloud Foundation and VMware vSphere Foundation roles. One current example is the VCP – VMware vSphere Foundation Administrator certification, which uses the VMware vSphere Foundation 9.0 Administrator exam, 2V0-16.25.

This multi-step history illustrates why exam rehabilitation must distinguish “replacement at retirement” from “current replacement today.” The first is useful historical context. The second is what a candidate needs for an actual certification decision.

Virtualization fundamentals still transfer

An ESXi host still abstracts physical CPU, memory, storage, and network resources into a platform that can run virtual machines. vCenter still provides centralized management for multiple hosts and clusters. Virtual hardware, guest operating systems, templates, snapshots, and resource controls remain part of the administrator’s mental model.

What changes across product generations is the capability and implementation detail around those foundations. Features become more integrated, hardware support shifts, security defaults evolve, and cloud-foundation operations create new lifecycle and automation expectations.

A legacy 2V0-620 learner should therefore preserve conceptual knowledge while verifying every command, interface path, limit, licensing assumption, and feature name against the current product. Old screenshots are especially poor evidence for current administration.

Storage knowledge should focus on design and failure behavior

vSphere administrators need to understand how virtual machines consume storage and what happens when storage becomes unavailable, slow, full, or inconsistent with policy. Traditional VMFS and NFS concepts remain useful, while modern VMware environments can also involve vSAN and broader software-defined storage designs.

A strong learning exercise is to trace one virtual disk from the guest through the datastore to the underlying storage system. Identify which layer owns capacity, performance, redundancy, snapshots, and failure recovery. Then ask what evidence would distinguish a guest problem from a datastore problem or a physical storage problem.

This style of reasoning transfers much better than memorizing the exact menu used by a vSphere 6 client. It also aligns with current operations, where administrators are expected to interpret health and policy rather than only provision a LUN.

Virtual networking remains a core administrator skill

Virtual machines depend on virtual switches, port groups, uplinks, VLANs, and physical network connectivity. A networking problem can exist at the guest, virtual switch, host uplink, physical switch, routing, or firewall layer, so administrators need a layered troubleshooting method.

Legacy exam material can still be useful for understanding standard versus distributed switching concepts, segmentation, redundancy, and how VM network interfaces connect to the physical environment. Current deployments may add automation and policy layers, but the packet still has to traverse real interfaces and networks.

Comparing VMware vSphere and XenServer separates durable hypervisor concepts from product-specific implementation choices.

Clusters turn isolated hosts into an availability system

A single hypervisor can run virtual machines, but enterprise vSphere value comes from managing pools of hosts. Clustering enables workloads to move, restart, balance resources, and survive certain failures according to the capabilities and policies in use.

Candidates should distinguish live migration from high availability. Moving a running workload between healthy hosts solves a different problem from restarting a workload after a host fails. Distributed resource management solves a different problem again by balancing placement and resource pressure.

For current study, focus on prerequisites and failure modes. What network and storage access does migration require? What happens when a host is isolated? How much spare capacity is needed to survive failures? Which dependencies can make a “highly available” cluster still vulnerable to a shared outage?

Permissions and identity deserve more attention than old foundation exams often gave them

Virtualization platforms control infrastructure with enormous privilege. An administrator can create machines, attach storage, change networks, access consoles, and potentially expose sensitive workloads. Modern security expectations therefore make identity, least privilege, logging, and administrative separation critical.

Study role-based access as an operational design. Identify who can administer hosts, who can create VMs, who can change networking, who can manage templates, and who can view but not modify sensitive environments. Avoid broad shared administrator accounts.

Also protect the management plane itself. Restrict access to vCenter and host management interfaces, use supported authentication integrations, monitor administrative events, patch management components, and keep recovery procedures for lost access or failed identity dependencies.

Lifecycle management is now a first-class platform responsibility

A vSphere 6-era foundations course could treat installation and patching as individual administrative tasks. Current platform operations put more emphasis on lifecycle consistency across clusters and integrated components. Firmware, drivers, host images, management appliances, and compatibility all affect safe upgrades.

Before an upgrade, administrators should check supported paths and interoperability rather than assuming that every old configuration can jump directly to the newest release. Backups, rollback planning, maintenance windows, hardware compatibility, and application dependencies all belong in the change plan.

This is another reason not to follow a legacy 2V0-620 lab literally. The architectural lesson may survive while the supported upgrade process does not.

Troubleshooting should start from evidence and scope

A useful vSphere troubleshooting sequence begins by defining scope. Is one VM affected, one host, one datastore, one network segment, or the whole management plane? Then inspect recent changes and health evidence before making broad configuration changes.

For a slow VM, check guest utilization, host contention, storage latency, network behavior, and any cluster-level alarms. For a disconnected host, distinguish management network failure from host failure. For inaccessible storage, identify whether the issue is pathing, credentials, network, capacity, or the storage system itself.

Legacy tools and screens can change, but this evidence-first process remains stable. The best administrator can explain what each observation rules in or out rather than applying a memorized fix to every symptom.

Current certification decisions should start with role and platform

Broadcom now lists current VMware certifications by product and role. For an administrator focused on VMware vSphere Foundation 9, the VCP – VVF Administrator path is far more relevant than a vSphere 6 foundations archive. VMware Cloud Foundation roles extend into the integrated private-cloud stack.

Before choosing an exam, confirm which product your organization actually runs, which role you need to perform, and which current credential maps to that role. A vSphere administrator may need a different path from a cloud-foundation architect, network specialist, automation professional, or support engineer.

Current certification preparation should therefore begin with the official catalog and current objectives, while historical ExamSnap content is used only as supporting background. That prevents an old exam code from becoming a false career destination.

Free and low-cost learning can help rebuild the foundation

Professionals returning to VMware after several years may not need to start with an expensive boot camp. Vendor documentation, hands-on labs, community material, home-lab options, and employer environments can help re-establish the foundation before formal exam preparation.

Free and low-cost VMware certification training can help rebuild the foundation before formal exam preparation. The goal is to reach a point where current objectives describe tasks you can perform or explain, not merely terms you recognize.

If a lab is used, document each exercise as a real operational scenario: desired state, change, verification, failure case, and rollback. That turns clicking through interfaces into transferable administration skill.

The right lesson from 2V0-620 is continuity, not nostalgia

2V0-620 mattered because it introduced administrators to the foundations of enterprise virtualization. Those foundations still have value, but the exam itself has been retired since 2019 and should not be presented as a current certification opportunity.

The modern path is to keep the durable concepts, refresh them against the platform generation you actually operate, and choose a current VMware certification that matches your role. That approach respects the historical purpose of the old page without misleading a candidate about availability.

For 2026 readers, “cracking 2V0-620” is no longer the objective. Understanding how vSphere fundamentals evolved into today’s VVF and VCF administration is the more useful outcome.

A useful modern lab can therefore keep the old foundations while changing the platform context. Build or observe an ESXi and vCenter environment, map management and workload networks, create a datastore, deploy a virtual machine, inspect permissions, test migration prerequisites, review cluster health, and document the lifecycle steps that keep hosts consistent. Then compare those tasks with the current VVF or VCF objective list instead of assuming an old 2V0-620 topic is still weighted the same way.

Role selection matters more than nostalgia for a familiar exam code. An administrator operating VMware vSphere Foundation needs a different depth from an architect designing Cloud Foundation or a support professional troubleshooting a private-cloud environment. Broadcom’s current certification catalog reflects those role distinctions, so a candidate should choose the current credential that matches the work being performed rather than chase a historical successor chain indefinitely.

The historical exam remains useful as a marker of how VMware administration evolved. It helps explain why ESXi, vCenter, clusters, storage, networking, and permissions remain foundational concepts even as licensing, lifecycle management, automation, and private-cloud integration have changed. The correct rehabilitation is to preserve that continuity while making the current certification decision from today’s platform and role requirements.
