NS0-304 study guide
NS0-304 · Work through your exam, one topic at a time.
The NetApp Certified Data Administrator, ONTAP (NS0-304) credential is aimed at storage and infrastructure professionals who administer NetApp ONTAP clusters day to day. It validates that you can build and manage aggregates and volumes, provision LUNs and file shares, configure NFS, SMB, and SAN client access, implement SnapMirror and SnapVault protection, tune and troubleshoot performance, apply security and access controls, and use automation and cloud integrations. The NS0-304 study guide has 8 sections and about 2,222 words.
01ONTAP Cluster Fundamentals and Administration
This domain tests how an ONTAP cluster is assembled, how quorum keeps it available, and the administrative tasks that keep it healthy. A cluster is a set of nodes managed as one system.
327 words, about 2 min02Storage and Aggregate Management
This domain tests how physical disks become RAID groups and aggregates, and how capacity and sparing decisions affect availability. Aggregates are RAID containers owned by one node and cannot span nodes.
296 words, about 1 min03Volume and LUN Provisioning
This domain tests how SVMs, flexible volumes, junctions, LUNs, and igroups deliver file and block storage. An SVM owns volumes, LIFs, and its namespace.
279 words, about 1 min04Networking and Client Access (NFS, SMB, SAN)
This domain tests LIF design, physical port configuration, and client protocol access for NFS, SMB, and SAN. Data LIFs serve client traffic; management LIFs serve administration; cluster LIFs carry intra-cluster traffic; intercluster LIFs carry SnapMirror traffic.
286 words, about 1 min05Data Protection and SnapMirror/SnapVault
This domain tests Snapshot copies, mirroring, backup retention, and recovery relationships. A Snapshot policy defines schedules and how many copies to retain.
258 words, about 1 min06Performance, Monitoring, and Troubleshooting
This domain tests how to measure ONTAP performance, interpret QoS, and isolate causes of slow client access. ONTAP reports latency, IOPS, throughput, and utilization.
268 words, about 1 min07Security, Access Control, and Compliance
This domain tests authentication, authorization, encryption, auditing, and immutable retention features. ONTAP role-based access control maps users and groups to roles with command or API permissions.
251 words, about 1 min08Automation, Scripting, and Cloud Integration
This domain tests programmatic ONTAP management and hybrid-cloud integration patterns. ONTAP exposes a REST API with versioned endpoints and a legacy ZAPI.
