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?
- A. Update the Removal schedule to the end of the month.
- B. Select Update and modify the Removal schedule.
- C. Remove the Removal schedule, then add the desired removal schedule.
- D. Update the Removal schedule to the desired date.
Answer: B
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.

NEW QUESTION # 49
How would an administrator enter the NDB command line to change the static IP address on the NDB VM?
- A. era-server
- B. arithmos cli
- C. era
- D. cerebro_cli
Answer: D
Explanation:
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.

NEW QUESTION # 54
An administrator needs to protect a database with a Point In Time Recovery (PITR) SLA that provides a minimum of seven days of log recovery.
What is the minimum Default SLA that meets this requirement?
- A. DEFAULT_008 GOLD SLA
- B. DEFAULT_008 SILVER SLA
- C. DEFAULT_008 BRONZE SLA
- D. DEFAULT_008 BRASS SLA
Answer: B
Explanation:
Nutanix Era (NDB) utilizes DEFAULT_008 SLAs with varying frequencies for snapshots and log backups to achieve different recovery point objectives (RPOs). Here's how they compare: DEFAULT_008 GOLD SLA: Typically has frequent log backups (e.g., every 15 minutes) and snapshots every few hours. This is designed for critical databases with very low RPOs.
DEFAULT_008 SILVER SLA: Offers a balance between protection and resource usage. Log backups might occur every hour with snapshots less frequently. This SLA is often suitable for databases requiring a good RPO without being overly resource-intensive.
DEFAULT_008 BRONZE SLA: Has less frequent log backups (e.g., every few hours) and less frequent snapshots. This is used for databases with less stringent RPO requirements.
DEFAULT_008 BRASS SLA: This has infrequent log backups and is usually considered the least protective SLA with the longest potential RPO Reasoning:
Since the requirement is to have at least a 7-day log recovery period, any SLA with more frequent log backups than daily is excessive. The DEFAULT_008 SILVER SLA, with its hourly log backups, easily satisfies this requirement, offering the ability to restore to a point in time within the last hour of the past seven days.

How can an administrator exclude Kernel patches for the Linux OS using the most efficient means?
- A. Define a pre-script to disable the repositories in the Patch Now advanced options
- B. Define a pre-script to disable the repositories in the Maintenance Window advanced options.
- C. Exclude the appropriate repositories on the VM prior to patching.
- D. Exclude the appropriate repositories on the VM and reboot prior to patching.
Answer: C
Explanation:
NDB supports Linux OS patching for database server VMs. Linux OS patching is performed by using the yum or apt package managers, depending on the Linux distribution. To exclude Kernel patches for the Linux OS, the administrator can disable or exclude the appropriate repositories on the VM prior to patching. This can be done by editing the yum.conf or apt.conf files, or by using the --disablerepo or -- exclude options in the yum or apt commands. This way, the administrator can control which patches are applied to the VM without affecting other VMs or requiring additional scripts or reboots.

Once the network is added to Era, it can be used for various operations such as provisioning new databases, managing existing databases, and more1.
NEW QUESTION # 60
What is the purpose of Data Access Management policies in NDB Multi-Cluster?
- A. To remove data accessibility of a time machine across all registered Nutanix clusters in NDB
- B. To register multiple Nutanix clusters in NDB
- C. To perform snapshot operations on a single Nutanix cluster
- D. To manage time machine data availability across all registered Nutanix clusters in NDB
Answer: D
Explanation:
Data Access Management (DAM) policies are a feature of NDB Multi-Cluster that allows you to control the access and availability of time machine data across different Nutanix clusters. You can use DAM policies to specify which clusters can access the time machine data of a source database, and which clusters can replicate the time machine data for backup or disaster recovery purposes. DAM policies help you to optimize the storage and network resources, as well as ensure the security and compliance of your database workloads. The purpose of DAM policies is not to register multiple Nutanix clusters in NDB, as this is done by using the Add Cluster option in the NDB settings page. The purpose of DAM policies is also not to perform snapshot operations on a single Nutanix cluster, as this is done by using the Time Machine feature in the NDB dashboard. The purpose of DAM policies is also not to remove data accessibility of a time machine across all registered Nutanix clusters in NDB, as this is done by using the Delete option in the Time Machine page.

NEW QUESTION # 61
An administrator has a production PostgreSQL database cloned for development and testing purpose. A new table is added to the source database.
What should the administrator do to publish the update leveraging the point in Time Era capability?
(C) 1. PeHorm a Log Catch-up using source database Time Mechine 2. Refresh the clone database (C) 1. Perform a Log Catch-up using source database Time Mechine
2. Refresh the source database
(C) l. update Log Catch-up interval from Tme Machine 2. Refresh the source database C) 1. Update Log Catch-up interval from Tame Machine 2. Refresh the clone database How is the size of a database time machine defined?
- A. Only the size of all reclaimable snapshots maintained by Era
- B. Only the size of all transaction logs maintained by Era
- C. The size of all snapshots and clones maintained by Era
- D. The size of all snapshots and/or transaction logs maintained by Era
Answer: D
Explanation:
The Nutanix Era platform provides a feature called Time Machine, which is designed to manage the lifecycle of database copies and clones1. When a new table is added to the source database, the administrator should perform a Log Catch-up using the source database's Time Machine. This action ensures that the Time Machine captures the latest state of the source database, including the newly added table1. After performing the Log Catch-up, the administrator should refresh the clone database.
The refresh operation updates the clone with the latest state captured by the Time Machine, thereby publishing the new table to the clone1.
NEW QUESTION # 62
Which Time Machine feature allows developers to automate the data refresh for their clones?
- A. Schedule
- B. update
- C. Manual Backup
- D. Log Catchup
Answer: A
Explanation:
According to the Nutanix Database Automation (NCP-DB) learning documents, the Schedule feature of the Time Machine allows developers to automate the data refresh for their clones1. This feature eliminates the time-consuming, complex process of database clone/refresh, allowing admins to create database clones/refresh to any point in time in just a few minutes1. Please refer to the official Nutanix documentation and training materials for more detailed information2.
NEW QUESTION # 63
An administrator would like to replicate database snapshots to remote Nutanix clusters.
What should the administrator do to manage Time Machine data availability across all registered Nutanix clusters in NDB?
- A. Add Data Access to each Nutanix cluster and assign a DAM policy.
- B. Update the SLA on the Time Machine & schedule the remote replication.
- C. Update the cluster's Data Access & select the remote cluster.
- D. Select the snapshots & replicate them to each Nutanix cluster.
Answer: A
Explanation:
To replicate database snapshots to remote Nutanix clusters, the administrator needs to add Data Access to each Nutanix cluster and assign a Data Availability Management (DAM) policy. Data Access is a feature of NDB that enables cross-cluster data mobility and protection. A DAM policy defines the replication frequency, retention period, and priority of the database snapshots across the clusters. By adding Data Access to each Nutanix cluster and assigning a DAM policy, the administrator can manage the Time Machine data availability across all registered Nutanix clusters in NDB.
