An administrator selected Bronze SLA for Era Time Machine during database registration. Which two capabilities are supported by the Time Machine for this database? (Choose two,)
Correct Answer: B,D
The Nutanix Era Time Machine provides various capabilities depending on the Service Level Agreement (SLA) selected during database registration1. For a database with a Bronze SLA, the Time Machine supports both "Log Catch up" and "Snapshots"2. "Log Catch up" allows the Time Machine to keep up with the latest changes in the database by capturing log data2. "Snapshots" are point-in-time copies of the database that can be used for recovery or cloning2.
Question 2
How would an administrator enter the NDB command line to change the static IP address on the NDB VM?
Correct Answer: C
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.

Question 3
What is the minimum frequency in minutes configurable for NDB Log Catch-up operation?
Correct Answer: B
The minimum frequency configurable for the NDB Log Catch-up operation is 15 minutes. This setting determines how frequently the log catch-up process runs, which is crucial for maintaining data integrity and ensuring up-to-date database states.References:Nutanix Database Automation documentation, focusing on log management and catch-up operation settings.
Question 4
What does an NDB compute profile contain?
Correct Answer: A
An NDB compute profile defines the CPU and memory resources for the database server VMs that are provisioned using NDB. It does not include any information about the network, domain, or software of the database server VMs. Those are specified in separate profiles, such as network profile, domain profile, and software profile.

Question 5
Which two network prerequisites are required to deploy an Era instance in production? (Choose two.)
Correct Answer: A,B
* Option A: Nutanix Era requires network prerequisites like NTP, DNS servers, gateway, and subnet mask to be available and visible. These are essential for the proper functioning of the Era instance1. * Option B: One static IP address must be available and can be changed using CLI after VM deployment. This is necessary for the Era VM to communicate with other components in the network1. * Option C: While a storage container is necessary for Nutanix infrastructure, it is not a network prerequisite specifically for deploying an Era instance. * Option D: An SMTP server and details are typically used for sending notifications, but they are not a network prerequisite for deploying an Era instance. They are more related to the operational aspect post-deployment.
