What are the LIF roles that can be assigned to ports in clustered ONTAP? (choose all that apply)
The correct answer is A. Data B. Cluster management C. Cluster D. Node management E. Intercluster. All five LIF roles - Data, Cluster management, Cluster, Node management, and Intercluster - are valid assignable roles for logical interfaces in clustered ONTAP.

Why each option
All five LIF roles - Data, Cluster management, Cluster, Node management, and Intercluster - are valid assignable roles for logical interfaces in clustered ONTAP.
Data LIFs handle client-facing NAS and SAN protocol traffic and are the primary role for serving application data. They can be hosted on any data port and support failover policies.
Cluster management LIFs provide a single, cluster-wide management IP address used for administering the entire cluster rather than individual nodes. They are distinct from node management LIFs.
Cluster LIFs carry intra-cluster communication traffic over the dedicated cluster interconnect network between nodes. They operate exclusively on cluster ports and use system-defined failover groups.
Node management LIFs provide individual per-node management access for out-of-band administration tasks such as remote console and system services. Each node typically has one node management LIF.
Intercluster LIFs are dedicated to cross-cluster traffic including SnapMirror replication, cluster peering, and SnapVault. They must be on ports with intercluster role to function correctly.
