The NDB alert retention feature allows the database administrator to configure the duration for which the NDB alerts are stored and displayed in the NDB instance. The NDB alert retention feature supports alert retention globally, meaning that the same retention period applies to all the alerts generated by the NDB instance, regardless of the source cluster, policy, or operation. The database administrator can set the alert retention period from 1 day to 365 days, or choose to retain the alerts indefinitely. The NDB alert retention feature helps to manage the storage space and the visibility of the NDB alerts.

The NDB alert retention feature does not support retention at the individual policy, grouped policy, or registered cluster level. The NDB alert retention feature applies to all the alerts uniformly, and does not allow the database administrator to specify different retention periods for different policies or clusters.

The correct answer is D. When setting up a 3-node MSSQL Server AG with two database server VMs on a local site and a third database server VM on a remote site, the network at each site will require the following IP addresses:

• 1 Cluster VIP and 1 Listener IP on the local site123.
• 1 Cluster VIP and 1 Listener IP on the remote site123.
• 2 IPs in the local site and 1 on the remote site for the database server nodes123.

This configuration ensures that each node in the cluster has a unique IP address, and each cluster and listener also has a unique IP address. This is necessary for the proper functioning of the cluster and to ensure that all nodes can communicate with each other and with clients123.

To change the static IP address on the NDB VM, an administrator would need to enter the NDB command line using the cerebro_cli command. The cerebro_cli command is used to access the Cerebro service, which is responsible for managing the NDB instance and its components. The cerebro_cli command can be run from the NDB VM or from any other VM that has network connectivity to the NDB VM. The cerebro_cli command has various subcommands and options to perform different tasks, such as changing the IP address, hostname, password, or certificate of the NDB VM. To change the static IP address, the administrator would need to use the cerebro_cli network update subcommand with the appropriate parameters, such as the new IP address, netmask, gateway, and DNS servers. The cerebro_cli network update subcommand also requires the administrator to provide the current password of the NDB VM for authentication. After changing the IP address, the administrator would need to restart the NDB VM for the changes to take effect. References:

 The correct answer is C because the NDB Database Agent service is responsible for scheduling and monitoring the NDB-related operations, such as provisioning, patching, cloning, and restoring databases. The NDB Database Agent service is deployed on the NDB server and on each of the database server VMs provisioned by NDB. It contains the tools required to perform each task and communicates with the NDB server through the NDB API. The other options are not correct because they describe different components or functions of the NDB solution. Option A is not correct because the transaction logs are not stored by the NDB Database Agent service, but by the NDB Time Machine service, which is a distributed file system that stores the database snapshots and logs. Option B is not correct because the source databases are not hosted by the NDB Database Agent service, but by the database server VMs, which are virtual machines that contain an instance of the database engine software and the database files. Option D is not correct because the NDB Database Agent service does not contain an instance of the database engine software, but only the tools required to perform the NDB-related operations. The database engine software is installed on the database server VMs, which are provisioned by NDB using the profiles defined by the administrator. 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 Support & Insights
