An administrator created a database clone that is scheduled for removal on the last day of the month.
A request has been received to keep the clone for an additional 14 days. After selecting the desired clone, how should the administrator satisfy this task?

  1. Update the Removal schedule to the desired date.
  2. Update the Removal schedule to the end of the month.
  3. Remove the Removal schedule, then add the desired removal schedule.
  4. Select Update and modify the Removal schedule.

Answer(s): D

Explanation:

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.

Which policies define Time Machine data availability across multiple registered clusters in NDB?

  1. Recovery Plans
  2. Data Access Management
  3. Data Protection
  4. Service Level Agreements

Answer(s): A

Explanation:

The recovery plans policy defines the Time Machine data availability across multiple registered clusters in NDB. The recovery plans policy allows the database administrator to specify the source and target clusters, the frequency and retention of the cross-cluster snapshots, and the network and compute profiles for the recovery operations. The recovery plans policy helps to ensure the disaster recovery and business continuity of the NDB-managed databases in case of a cluster failure or outage.
The data access management policy defines the access permissions and roles for the NDB users and groups. The data access management policy allows the database administrator to grant or revoke access to the NDB instance, the database server VMs, the databases, and the database operations. The data access management policy helps to ensure the security and compliance of the NDB- managed databases and users.
The data protection policy defines the backup and restore settings for the NDB-managed databases. The data protection policy allows the database administrator to specify the frequency, retention, and compression of the database snapshots, and the backup location and encryption for the database backups. The data protection policy helps to ensure the backup and recovery of the NDB-managed databases within the same cluster.
The service level agreements policy defines the performance and availability metrics for the NDB- managed databases. The service level agreements policy allows the database administrator to monitor and enforce the database uptime, latency, throughput, and IOPS. The service level agreements policy helps to ensure the quality of service and performance of the NDB-managed databases.

An administrator has configured NDB HA across multiple Nutanix clusters.
Which failure scenario will require manual interaction for the recovery?

  1. More than one API Server VM is down.
  2. One repository VM is down.
  3. More than one HA proxy VM is down.
  4. NDB Server process is down.

Answer(s): A

Explanation:

NDB HA is a feature that provides high availability and resilience for the NDB service and its components. NDB HA creates a cluster of API server VMs, repository VMs, and HAProxy VMs across multiple Nutanix clusters. Each component has a leader and a set of followers that are synchronized and can take over the leader role in case of a failure. NDB HA also monitors the health and status of the NDB components and performs automatic failover and recovery actions when possible. However, some failure scenarios may require manual intervention from the administrator to restore the NDB service. One such scenario is when more than one API server VM is down. The API server VMs are responsible for handling the requests from the NDB UI and CLI, as well as communicating with the repository VMs and the HAProxy VMs. If more than one API server VM is down, the NDB service may become unavailable or unstable, and the administrator will need to manually restart or redeploy the affected API server VMs. The other options do not require manual interaction for the recovery, as NDB HA can handle them automatically. If one repository VM is down, NDB HA will fail over to another repository VM that has the latest data. If more than one HAProxy VM is down, NDB HA will route the traffic to the remaining HAProxy VMs. If the NDB server process is down, NDB HA will restart the process or fail over to another API server VM.

Which disk is omitted from a Software Profile?

  1. System Page File
  2. SQL Installation
  3. User Database
  4. System Database

Answer(s): A

Explanation:

According to the Nutanix Database Automation (NCP-DB) course, a Software Profile is a template that defines the configuration of the database engine, such as the version, edition, features, and parameters1. It also specifies the disk layout for the database installation, such as the size, type, and mount point of each disk1. However, the System Page File disk is omitted from the Software Profile, as it is automatically created by the NDB service based on the memory size of the database server

VM1. The other options are included in the Software Profile, as they are essential for the database operation and performance1.
