Understanding the NS0-164 Exam in Context
The exam is part of the NetApp Certified Data Administrator (NCDA ONTAP) credential. Employers value it because certified professionals can:- Configure and manage ONTAP clusters
- Handle day-to-day storage operations without downtime
- Troubleshoot performance and availability issues
- Protect data through backups, snapshots, and replication

The Knowledge Areas – What You’re Expected to Know
- ONTAP Fundamentals ONTAP is the brain of NetApp’s storage system. You need to know its architecture: clusters, nodes, aggregates, and volumes.
- Networking for Storage ONTAP storage doesn’t live in isolation—it must talk to clients. The exam tests VLANs, LIFs, and multipathing.
- Storage Provisioning You’ll face tasks like creating LUNs, FlexVols, qtrees, and exports. Think of this as the “daily bread” of an administrator.
- Data Protection SnapMirror, SnapVault, and Snapshot copies are all exam staples. The ability to replicate data to another site could save a business from disaster.
- High Availability HA pairs, failover mechanisms, and MetroCluster concepts ensure storage systems never become a single point of failure.
- Security and Compliance With ransomware on the rise, you need to secure ONTAP with RBAC, encryption, and audit tools.
- Monitoring and Troubleshooting Expect scenario-based questions where you must identify problems using logs, OnCommand tools, or CLI outputs.
A Fresh Study Approach
Instead of memorizing topics, use a role-play method:- Pretend you’ve just been hired as a junior storage admin.
- Your manager asks: “Set up storage for our new application team. Make sure it’s secure, backed up, and accessible.”
- Break this down into real tasks—create aggregates, provision shares, configure SnapMirror, test failover.
Week-by-Week Roadmap
- Week 1–2: Build the Foundation Install the ONTAP simulator. Learn the CLI and System Manager interface. Focus on aggregates, SVMs, and volumes.
- Week 3–4: Networking and Provisioning Configure LIFs, VLANs, and multipathing. Practice creating NFS exports and CIFS shares.
- Week 5: Data Protection Set up SnapMirror between two simulator nodes. Create snapshot policies and test restores.
- Week 6: High Availability Explore HA pairs and failover testing. Read case studies of MetroCluster deployments.
- Week 7: Security Apply role-based access, configure audit logs, and test encryption features.
- Week 8: Mock Exams and Review Take two or three practice exams. Focus your review on weak areas. Summarize commands and concepts into a personal “quick reference” document.
Overcoming Common Struggles
- Command Overload: ONTAP CLI is huge. Solution → Write down frequently used commands and practice them daily.
- Networking Confusion: Candidates often get lost in VLANs and multipathing. Solution → Draw diagrams; visualize traffic flow.
- Scenario Questions: The exam loves “what would you do first?” questions. Solution → Practice logical troubleshooting order: identify → isolate → resolve.
Exam Day Strategy
- Pace Yourself: With 60 questions in 90 minutes, you have 1.5 minutes per question. Don’t rush the first half.
- Elimination Trick: Two answers will usually be obviously wrong. Focus on the remaining two.
- Scenario Questions: Always ask, “what’s the safest action with the least risk to data?” That’s usually the correct choice.
- Stay Calm: Remember, the exam tests what you already practiced in your lab.
Career Impact
Passing NS0-164 can reshape your career. Certified professionals are trusted with critical data systems. Possible roles include:- Storage Administrator – managing day-to-day NetApp environments
- Infrastructure Engineer – integrating storage into larger IT systems
- Disaster Recovery Specialist – ensuring data protection and continuity
- Consultant – advising businesses on storage solutions
