NS0-157 · Question #199

What are three types of resource supported by logical interfaces? (Choose three)

The correct answer is B. port C. Interface groups H. VLAN. Logical interfaces (LIFs) in Clustered ONTAP are hosted on physical ports, interface groups, and VLANs as their supported underlying network port resources.

Why each option

Logical interfaces (LIFs) in Clustered ONTAP are hosted on physical ports, interface groups, and VLANs as their supported underlying network port resources.

AVServer-routes

VServer-routes are routing table entries associated with a Vserver's network configuration, not a port resource type on which a LIF is hosted.

BportCorrect

Physical ports are a valid and direct home port resource for LIFs, allowing a LIF to be bound to a specific network port on a node.

CInterface groupsCorrect

Interface groups (link aggregation groups or LAGs) are a supported LIF home port resource type that provide link redundancy and increased bandwidth for LIF traffic.

Dfailover groups

Failover groups define the set of ports a LIF may migrate to during failover, but they are a policy construct rather than a resource type on which a LIF is placed.

Ecluster-routes

Cluster-routes are internal routing constructs for cluster interconnect traffic and are not a valid home port resource type for data LIFs.

Fcluster

A cluster is a logical grouping of all nodes in the ONTAP system and is not a network resource type on which a LIF can be hosted.

Ggroup-routes

Group-routes is not a recognized resource or port type in the Clustered Data ONTAP LIF framework.

HVLANCorrect

VLANs are a supported LIF home port resource that enable network segmentation and traffic isolation, allowing LIFs from different Vservers or protocols to share a physical port.
