Nutanix NCP-DB Exam With Confidence Using Practice Dumps

 The correct answer is B and D because they are the two restore options that can be used to restore an Oracle database to the prior day’s state using Nutanix Era. A snapshot is a point-in-time copy of a database that is stored in the Era Time Machine, which is a distributed file system that collects logs and snapshots from databases. A point in time is a specific moment in time within the retention period of the SLA policy that is applied to the database. By using either of these options, the administrator can select the snapshot or the point in time that corresponds to the prior day’s state and restore the database from it. The other options are not correct because they are not restore options that are available in Nutanix Era. Option A is not correct because Most Recent Time Available is not a restore option, but a clone option that creates a clone of the database from the most recent snapshot or log backup. Option C is not correct because Tail Logs Backup is not a restore option, but a backup option that captures the transaction logs of the database that have not been backed up by the SLA policy. References: Nutanix Database Management & Automation (NDMA) course, Nutanix Certified Professional - Database Automation (NCP-DB) certification, Nutanix NCP-DB Certification Exam Syllabus and Study Guide, [Nutanix Database Services: Database modernization with Era - Now available]

Time Machine data access is a feature of Nutanix Database Service (NDB) that allows you to access a point-in-time snapshot of a database without restoring it. To use this feature, you need to create a Data Access Management (DAM) policy that defines the access mode, the source database, the destination cluster, and the storage container mapping. The storage container mapping is needed when the source database and the NDB Server containers are different, because NDB needs to know where to store the metadata and the clone of the source database. If the source database and the NDB Server containers are the same, then NDB will use the same container for both the metadata and the clone. References:

To enable iSCSI connections between the Nutanix Database Service (NDB) server, Controller VMs (CVMs), and Prism Element, a Data Services IP must be configured in Prism Element. The Data Services IP acts as a cluster-wide address that facilitates iSCSI target discovery and connectivity. It is used by Nutanix Volumes (a block storage service) to present storage to external clients or services, such as the NDB server, via the iSCSI protocol. This IP ensures that iSCSI traffic is routed correctly and remains available even if a CVM fails, as ownership of the Data Services IP can move to another CVM in the cluster.

Configuring the Data Services IP is a prerequisite for integrating NDB with a Nutanix cluster, as NDB relies on iSCSI to manage database storage operations like provisioning and cloning. Without this configuration, the NDB server cannot establish the necessary connections to the CVMs for database-related tasks. Options like Virtual IP, Secondary DNS IP, and Backplane IP are not relevant in this context:

Virtual IP: This is typically associated with high-availability setups for applications, not iSCSI connectivity.

Secondary DNS IP: This pertains to network resolution, not storage connectivity.

Backplane IP: This is an internal network IP for cluster communication, not for external iSCSI access.

Thus, the correct and verified answer is the Data Services IP.
