Nutanix Updated NCP-DB Exam Questions and Answers by edwin

The administrator can add a stretched VLAN in NDB using either static or dynamic VLANs. A stretched VLAN is a VLAN that spans across multiple Nutanix clusters, and allows the NDB-managed databases to communicate and migrate between different clusters. A static VLAN is a VLAN that is manually configured and assigned to the database server VMs and the databases by the administrator. A dynamic VLAN is a VLAN that is automatically configured and assigned to the database server VMs and the databases by the NDB instance, using the Nutanix Calm orchestration service. Both static and dynamic VLANs can be used to create a stretched VLAN in NDB, as long as they have the same VLAN ID and network configuration across the clusters.

The administrator cannot add a stretched VLAN in NDB using only VLANs that are not managed in NDB. A VLAN that is not managed in NDB is a VLAN that is configured and assigned to the database server VMs and the databases outside of the NDB instance, using the Nutanix Prism web console or other tools. A VLAN that is not managed in NDB cannot be used to create a stretched VLAN in NDB, as it is not recognized or controlled by the NDB instance.

To register an Oracle Database Server VM to Era in Nutanix Database Automation (NCP-DB), certain dependencies must be met. One of these is that SUDO NOPASS access is required1. This allows the Era service to perform necessary operations on the Oracle Database Server VM. As for assigning a static IP address to the Era VM on ESXi, you can use the vSphere Client to configure static IP settings2. However, this is not directly related to the registration of an Oracle Database Server VM to Era. Please note that these answers are based on the information available as of my last update in 2021 and may need to be verified with the most recent Nutanix Database Automation (NCP-DB) documentation or resources.

For an NDB offline upgrade, you need to download the upgrade bundle from the Nutanix Support Portal and copy it to the NDB server. Then, you need to use the NDB CLI command upload upgrade_bundle with the path parameter to specify the location of the upgrade bundle file. This command will upload the upgrade bundle to the NDB server and verify its integrity. After uploading the upgrade bundle, you can use the upgrade command to perform the upgrade. References: Nutanix Support & Insights, Cisco Nexus Data Broker Deployment Guide, Release 3.10.x

• Option A: On the Era Dashboard Database Summary Table under Source Database. The dashboard provides a summary of the databases, including their sizes1.
• Option B: Under the Capacity widget on the Database Server VMS > List database summary page. While this might provide information about the capacity, it does not specifically provide the size of a Source Database.
• Option C: On the Databases > Sources table. This table provides detailed information about the databases, including their sizes1.
• Option D: On the Profiles > Database Parameters list for the assigned DB Parameter Profile. This list provides parameters for the database but does not provide the size of a Source Database.
