A healthcare administrator configure a Nutanix cluster with the following requirements: • Enable for long-term data retention of large files • Data…

The core requirements are long-term, immutable storage for large files, specifically preventing deletion or overwrites for two years. Nutanix Objects with WORM (Write-Once, Read-Many) is designed precisely for this use case. WORM locks an object for a specified retention period, making it impossible to modify or delete until that period expires. This functionality is critical for compliance and data protection scenarios common in healthcare. Nutanix Objects is also the ideal platform for storing large, unstructured files for long-term retention.

A. Files – Connected share: A standard connected share is read/write by default and does not prevent data deletion or modification, failing the immutability requirement.

B. Files – Read-only share: This is a share-level permission that prevents modification through that specific share but does not provide true data immutability; an administrator could still delete the underlying data.

D. Objects – Life Cycle Policy: This feature is used to automate the management of data, such as tiering to different storage or deleting it after a certain time, which is contrary to the requirement of preventing deletion.

1. Nutanix Objects User Guide v4.1

Section: WORM (Write Once Read Many). "WORM (Write Once Read Many) allows you to transition data into a WORM state

preventing its deletion for a pre-defined period. You can enable WORM at the bucket level. When you enable WORM for a bucket

you can specify a default retention period for the objects in that bucket." This directly supports the use of WORM for time-based

immutable retention.

2. Nutanix Objects User Guide v4.1

Section: Lifecycle Policies. "A lifecycle policy allows you to manage your objects efficiently... You can define rules in a lifecycle policy to automatically move objects to a different storage class or delete objects after a specified period." This confirms that lifecycle policies are for data management and deletion

not immutability.

3. Nutanix Files User Guide v4.4

Section: Creating an SMB Share. The documentation on share permissions describes settings like "Full control

" "Modify

" and "Read & execute." A read-only setting is a client access control

not a fundamental data immutability feature like WORM.
