NetApp Exam NS0-304 Topic 2 Question 12 Discussion

Actual exam question for NetApp's NS0-304 exam

Question #: 12
Topic #: 2

An administrator deploys Cloud Volumes ONTAP (CVO) in a highly available configuration across multiple availability zones in AWS. They want to ensure NAS connectivity during a failover event.

What will enable this functionality?

ADedicated tenancy

BFloating IP address

CSubnet CIDR reservations

DMPIO/ALUA

Show Suggested Answer

Suggested Answer: B

In a highly available Cloud Volumes ONTAP deployment across multiple availability zones in AWS, ensuring NAS connectivity during a failover event requires the use of a Floating IP address. Here's the rationale:

Functionality of Floating IP: A Floating IP in a NetApp CVO HA environment acts as a stable network point that clients can connect to. It automatically moves between nodes in different availability zones based on where the active node is located, thereby maintaining connectivity even if one node fails.

Failover Efficiency: The Floating IP minimizes downtime by providing a quick and automatic reroute of network traffic to the surviving node without requiring DNS changes or manual intervention.

High Availability and Resilience: Using a Floating IP ensures that applications accessing the NAS volumes experience no perceptible downtime in the event of a node failure, maintaining continuous availability and access.

For more information on setting up and managing Floating IPs in a NetApp CVO HA environment in AWS, consult the NetApp Cloud Volumes ONTAP HA documentation: NetApp Documentation on Cloud Volumes ONTAP HA.

I'm not so sure about the subnet CIDR reservations. Seems like that might be overkill for this scenario. Floating IP is the way to go, in my opinion.

Floating IP address sounds like the most logical choice. It'll keep the network connection up and running even if the instance fails over.
