NS0-529 and NS0-594: NetApp Updates Two Certification Exams for 2026

NetApp has refreshed two important certification exams for 2026, with NS0-529 replacing NS0-528 for the NetApp Certified Implementation Engineer – Data Protection path and NS0-594 replacing NS0-593 for the NetApp Certified Support Engineer ONTAP Specialist path. Candidates preparing for either certification should now shift their attention to the new exam codes and make sure their study plans reflect the latest objectives. To support this transition, Passcert has updated its NS0-529 and NS0-594 practice tests with coverage of the key concepts and skills candidates need to review for the new exams.

NetApp's current 2026 certification lineup lists NS0-529 for the Implementation Engineer Data Protection Specialist credential and NS0-594 for the Support Engineer ONTAP Specialist credential.

NetApp Exam Changes at a Glance

These changes continue two established NetApp certification paths rather than creating completely different credentials. For candidates who had already started preparing for NS0-528 or NS0-593, much of the underlying knowledge remains useful, but the new exam codes and current objectives should now become the basis of preparation.

NS0-529 Replaces NS0-528 for NetApp Data Protection Certification

The NS0-529 NetApp Certified Implementation Engineer – Data Protection exam is designed for professionals who work with NetApp data protection solutions, evaluate customer data storage requirements, and implement backup, recovery, and disaster recovery solutions.

NetApp recommends that candidates have approximately six to twelve months of experience with ONTAP replication technologies and with planning, implementing, and administering NetApp data protection and recovery solutions. Candidates are also required to first achieve the NetApp Certified Data Administrator (NCDA) certification.

The certification is therefore aimed at professionals who need to translate business protection requirements into practical NetApp configurations rather than simply understand individual storage features.

What Does the NS0-529 Exam Test?

The current NetApp Data Protection exam objectives are organized into five major domains.

1. Data Protection Solutions

This area focuses on selecting and understanding data protection solutions, working with design documentation, and identifying dependencies between different components of a protection solution.

Candidates should understand how business and technical requirements influence the design of backup, replication, and recovery strategies.

2. NetApp ONTAP Core Data Protection Features

Candidates are expected to understand data protection and redundancy within ONTAP environments, including how storage efficiency relates to data protection.

The domain also includes deploying data protection solutions in hybrid-cloud environments, making it important to understand how protection extends beyond a single on-premises storage system.

3. NetApp Data Protection Software

This section evaluates the ability to deploy and administer NetApp data protection software.

Candidates should also understand data protection approaches for Kubernetes applications, reflecting the growing importance of protecting workloads across modern application environments.

4. NetApp ONTAP Business Continuity Solutions

Business continuity is another important part of NS0-529 preparation. Candidates should be familiar with technologies and operations including:

● SnapMirror active sync

● SVM-DR operations

The focus is not simply on knowing what these technologies are, but on understanding how they support availability, replication, failover, and recovery requirements.

5. Troubleshooting and Testing

The final domain focuses on what happens when protection or recovery does not work as expected.

Candidates should understand how to troubleshoot data protection configurations as well as perform disaster recovery and data restore procedures.

NetApp also identifies tools such as SnapCenter, NetApp Console/BlueXP, System Manager, Active IQ tools, Hardware Universe, CLI, SSH, ping, and traceroute as relevant technologies or utilities candidates should be familiar with.

What Changed from NS0-528 to NS0-529?

The move from NS0-528 to NS0-529 should be viewed as an update to the existing Data Protection certification path rather than a complete change in direction.

The central skills remain closely connected to protecting NetApp environments: replication, backup and recovery, business continuity, data protection software, hybrid-cloud protection, and troubleshooting.

This means candidates who previously prepared for NS0-528 can reuse much of their foundational knowledge. However, older study material should not be treated as the final reference for the new exam content.

For NS0-529, preparation should place particular attention on:

● ONTAP replication and protection technologies

● Backup schedules and protection policies

● SnapMirror and SnapMirror active sync

● SVM disaster recovery

● Hybrid-cloud data protection

● NetApp data protection software

● Kubernetes application protection

● Backup and restore procedures

● Disaster recovery workflows

● Troubleshooting data protection configurations

The key preparation goal is to understand how these technologies work together in real implementation scenarios.

NS0-594 Replaces NS0-593 for NetApp Support Engineer ONTAP Specialist

The second major NetApp exam update is NS0-594 exam, which replaces NS0-593 in the NetApp Certified Support Engineer ONTAP Specialist path.

NetApp describes this certification as validating the ability to troubleshoot, analyze, and resolve issues in NetApp ONTAP storage systems. Candidates are expected to have approximately six to twelve months of relevant troubleshooting and support experience and must first achieve the NetApp Certified Support Engineer ONTAP Professional certification.

That makes NS0-594 significantly more troubleshooting-oriented than a general administration exam. Candidates need to understand not just how ONTAP features are configured, but how to investigate failures and identify the most appropriate resolution.

What Does the NS0-594 Exam Test?

The current NS0-594 objectives are divided into four major areas: ONTAP OS, Hardware, Protocols, and Performance.

1. ONTAP OS

This is one of the most important areas for NS0-594 candidates.

Topics include:

● Tools used for support and troubleshooting

● ONTAP cluster administration

● Data replication issues

● ONTAP OS structure

● Troubleshooting ONTAP

● Handling panic events

Candidates should be comfortable moving from a reported symptom to the appropriate diagnostic process rather than relying on memorized commands alone.

2. Hardware

The Hardware domain focuses on identifying and resolving physical infrastructure problems.

Candidates should understand:

● Hardware troubleshooting

● SP and BMC troubleshooting

● Fibre Channel hardware components

● Cluster interconnect infrastructure

● MetroCluster configurations

This requires an understanding of how NetApp hardware components interact with ONTAP and how hardware failures can affect system availability or connectivity.

3. Protocols

NS0-594 also evaluates the ability to support the major protocols used for data access.

Candidates should be prepared for troubleshooting scenarios involving:

● ONTAP NAS configurations

● ONTAP SAN configurations

● S3 server configurations

Rather than studying protocols independently, candidates should consider how configuration, networking, storage, and client-side symptoms can be connected during troubleshooting.

4. Performance

The final domain concentrates on ONTAP performance.

Candidates need to understand:

● ONTAP performance concepts

● Troubleshooting ONTAP performance

● Software-defined ONTAP solutions

Performance questions may require candidates to distinguish between storage, network, workload, configuration, and system-level causes before selecting an appropriate troubleshooting action.

What Changed from NS0-593 to NS0-594?

The transition from NS0-593 to NS0-594 keeps the certification centered on advanced ONTAP support and troubleshooting.

Core areas such as ONTAP OS, hardware, protocols, replication, MetroCluster, and performance continue to be highly relevant. Therefore, candidates who already have NS0-593 knowledge do not need to abandon everything they have studied.

The better approach is to use that knowledge as a foundation while updating preparation around current NS0-594 objectives and current ONTAP support practices.

For the new exam, candidates should be comfortable with scenario-based tasks such as:

● Identifying the source of an ONTAP problem

● Selecting appropriate troubleshooting tools

● Investigating cluster and replication issues

● Diagnosing SP or BMC problems

● Troubleshooting Fibre Channel environments

● Resolving NAS, SAN, and S3 configuration issues

● Working with MetroCluster-related problems

● Analyzing ONTAP performance symptoms

● Determining an appropriate remediation path

This makes practical troubleshooting experience especially valuable for NS0-594 preparation.

Why Do NS0-528 and NS0-593 Still Appear on Some NetApp Pages?

Candidates researching these certifications may notice that some NetApp pages still reference NS0-528 or NS0-593.

This can happen during a certification documentation transition. NetApp's current INSIGHT 2026 certification listing identifies NS0-529 as the Data Protection Specialist exam and NS0-594 as the Support Engineer ONTAP Specialist exam, while some older certification policy and practice-exam pages still contain references to NS0-528 and NS0-593.

For anyone beginning preparation now, the important point is to recognize the replacement relationship:

NS0-528 → NS0-529

NS0-593 → NS0-594

Candidates should confirm the current exam code in NetApp's registration system before scheduling their exam and make sure their preparation resources correspond to the latest version.

NS0-529 vs. NS0-594: Which NetApp Exam Should You Take?

Although NS0-529 and NS0-594 are both specialist-level NetApp exams, they validate different professional skills.

The difference can be summarized simply: NS0-529 focuses on implementing and managing NetApp data protection solutions, while NS0-594 focuses on diagnosing and resolving advanced ONTAP problems.

How Should Candidates Prepare for the Updated NetApp Exams?

Candidates moving from the previous exam versions should avoid starting their preparation from zero. A more efficient strategy is to keep relevant foundational knowledge while updating anything tied to the current exam blueprint.

A practical preparation process is to:

1. Confirm the new exam code. Candidates previously targeting NS0-528 should move to NS0-529, while NS0-593 candidates should prepare for NS0-594.

2. Review the latest official exam objectives. Use the current NetApp certification pages as the primary reference for what is tested.

3. Compare existing notes with the new objectives. Identify areas that remain relevant and topics that require additional review.

4. Update older product knowledge. Pay attention to current NetApp terminology, tools, ONTAP functionality, and recommended workflows.

5. Focus on practical scenarios. NS0-529 requires implementation and recovery thinking, while NS0-594 requires strong troubleshooting and root-cause analysis skills.

6. Use updated practice tests to identify gaps. Practice should help candidates recognize weak areas rather than simply memorize isolated facts.

7. Strengthen hands-on familiarity. When possible, work with ONTAP management, protection, support, and troubleshooting tools in realistic scenarios.

For NS0-529, preparation should connect protection requirements with actual implementation decisions. For NS0-594, preparation should focus on moving systematically from symptoms to diagnosis and resolution.
