NS0-157 · Question #89
The cluster ha modify -configured true command will trigger which two actions? (Choose two.)
The correct answer is B. The ability for the hosts connected to a node to failover to another HA pair. C. The storage can failover from one node to the other. The cluster ha modify -configured true command activates the HA framework on the cluster, enabling storage failover between HA pair nodes and allowing hosts to redirect I/O when a node becomes unavailable.
Question
The cluster ha modify -configured true command will trigger which two actions? (Choose two.)
Options
- AThe ability for the nodes in an HA pair to execute an auto-giveback.
- BThe ability for the hosts connected to a node to failover to another HA pair.
- CThe storage can failover from one node to the other.
- DSVM failover from any node in the cluster to any other node.

Why each option
The cluster ha modify -configured true command activates the HA framework on the cluster, enabling storage failover between HA pair nodes and allowing hosts to redirect I/O when a node becomes unavailable.
Auto-giveback is a separate optional behavior controlled by the storage failover modify -auto-giveback command and is not triggered by cluster ha modify -configured true.
When HA is configured on the cluster, hosts connected to a failing node gain the ability to redirect I/O through the surviving partner node, enabling path-level failover at the host layer.
The cluster ha modify -configured true command is the prerequisite that activates storage failover, allowing one node to take over the storage resources and LIFs of its HA partner during an outage.
SVM failover across any arbitrary node in the cluster is a capability of SVM DR or MetroCluster, not a result of enabling basic HA with this command.
