Nutanix Updated NCP-DB Exam Questions and Answers by kareem

The "Savings over traditional cloning" metric in the Data Usage widget on the NDB dashboard reflects the efficiency of NDB’s cloning technology compared to traditional full-copy cloning methods. NDB leverages Nutanix’s near-zero byte cloning capability, which creates lightweight clones by sharing base data and only storing changes (deltas). This metric specifically quantifies the disk space saved by using these efficient clones instead of duplicating entire datasets, as would occur in traditional cloning. It highlights NDB’s storage optimization for database provisioning and management.

Option A is correct as it directly ties to NDB’s near-zero byte cloning technology, a core feature for space efficiency.

Option B (Compression) is incorrect because compression is a separate storage optimization technique not specifically tied to cloning savings.

Option C (Shadow clones) is incorrect because shadow clones are a Nutanix feature for caching, not the cloning mechanism used by NDB Time Machines.

Option D (Deduplication) is incorrect as deduplication, while related to storage savings, is not the primary mechanism reflected in this cloning-specific metric.

This metric helps administrators quantify the benefits of NDB’s cloning approach in terms of storage utilization.

The Era One-Click Provisioning service in Nutanix Database Automation (NCP-DB) simplifies and automates database administration. It brings one-click simplicity to database provisioning and life-cycle management. This service enables database administrators to provision, clone, and refresh the database clones to any point in time1. Specifically, it enables the creation of space-efficient clones and zero-byte database clones1. This is part of Era’s copy data management service, which includes components like Time Machine, one-click cloning and refresh, and one-click backup21.

The correct answer is B and D because these are the two status values that can be set within the Alerts Dashboard in NDB. Resolved means that the alert has been fixed and no longer requires attention. Acknowledged means that the alert has been seen and is being worked on. Option A is incorrect because Auto is not a status value, but a mode that automatically resolves alerts based on predefined rules. Option C is incorrect because Data Resiliency is not a status value, but a feature that ensures the availability and integrity of the data in NDB.

 Nutanix Era enables you to clone your source databases (running on Nutanix clusters) and refresh the database clones by using snapshots or transaction logs1. Era uses storage-efficient and time-efficient Nutanix snapshots, thus lowering the cost of managing multiple copies of your databases1. In this case, the administrator should create a clone from the July 31st snapshot in Time Machine to provide the legal team with the specific banking transaction event data they need for their audit1.
