Nutanix Updated NCP-DB Exam Questions and Answers by anton

 The correct answer is D because it matches the requirement of taking multiple snapshots per day and retaining them for one week. Option A is incorrect because it only takes one snapshot per day, which is not enough for the administrator’s need. Option B is incorrect because it only retains the snapshots for one week, which means the older snapshots will be deleted after seven days. Option C is incorrect because it only takes two snapshots per week, which is not frequent enough for the administrator’s need.

Time Machine is a feature of Nutanix Era that allows you to create and manage snapshots of your databases. You can use Time Machine to create clones from any snapshot, either manually or automatically. You can also configure Time Machine to create clones from snapshots based on a schedule, such as daily, weekly, or monthly. This way, you can ensure that your clones are always up to date with the latest data from your production databases. In this scenario, the most efficient way to meet the developer’s requirement is to configure Time Machine to create a clone from a daily snapshot at 7:00am. This will save the developer’s time and effort, as well as reduce the storage consumption by using the existing snapshots. References:

Ports 3205 and 3260 are important when working with Era because they must be open on the Era server and all Controller VMs (CVMs) to facilitate iSCSI connections1. Specifically, port 3205 is used for iSCSI redirection2. Please be careful of routing iSCSI traffic, as it could impact performance2.

The Removal schedule is a feature of Nutanix Era that allows you to specify when a database clone will be automatically deleted. You can modify the Removal schedule of an existing clone by selecting the clone from the Clones page, clicking on the Update button, and changing the Removal schedule option to the desired date. This way, you can extend or shorten the lifespan of a clone as per your requirements. You do not need to remove the existing Removal schedule and add a new one, as this would be an unnecessary step. You also do not need to update the Removal schedule to the end of the month, as this would not meet the request of keeping the clone for an additional 14 days. References:
