How would an administrator enter the NDB command line to change the static IP address on the NDB VM?

era-server
era
cerebro_cli
arithmos cli

Answer(s): C

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.

QUESTION: 10

Within the NDB GUI, an administrator needs to set the shortest schedule interval possible for a database log catch up.
Which value, in minutes, will satisfy this requirement?

Answer(s): C

Explanation:

The NDB GUI allows an administrator to set the schedule interval for a database log catch up, which is the process of collecting transaction logs periodically from the source databases and storing them in the time machine. The shortest possible value for this interval is 15 minutes, as per the NDB documentation1. This means that the NDB time machine will capture the database logs every 15 minutes and use them for backup, restore, clone, and refresh operations.

QUESTION: 11

While adding Time Machine data access to a Nutanix cluster, when is a storage container mapping needed

When the source database and NDB Server containers are different.
When the source database and NDB VM are on the same container.
When the source and destination database containers are different.
When the source database and NDB provisioning container are the same.

Answer(s): A

Explanation:

Time Machine data access is a feature of Nutanix Database Service (NDB) that allows you to access a point-in-time snapshot of a database without restoring it. To use this feature, you need to create a

Data Access Management (DAM) policy that defines the access mode, the source database, the destination cluster, and the storage container mapping. The storage container mapping is needed when the source database and the NDB Server containers are different, because NDB needs to know where to store the metadata and the clone of the source database. If the source database and the NDB Server containers are the same, then NDB will use the same container for both the metadata and the clone.

QUESTION: 12

An administrator needs to maintain five days of time-travel capability to any second, plus an additional seven days of discrete recovery at a daily interval. How should the administrator define the Frequency and retention on the SLA?

· Continuous log retention (days): 7
· Daily snapshot retention (days): 5
· Continuous log retention (days): 5
· Weekly snapshot retention (weeks): 1
· Weekly snapshot retention (weeks): 1
· Continuous log retention (days): 7
· Daily snapshot retention (days): 7
· Continuous log retention (days): 5

Answer(s): D

Explanation:

The correct answer is D because it meets the requirements of maintaining five days of time-travel capability to any second and an additional seven days of discrete recovery at a daily interval. Continuous log retention allows the administrator to restore the database to any point in time within the specified number of days, while snapshot retention allows the administrator to restore the database to a specific point in time at a fixed interval. Therefore, by setting the daily snapshot retention to 7 days, the administrator can ensure that there is a discrete recovery point for each day of the week. By setting the continuous log retention to 5 days, the administrator can ensure that there is a time-travel capability to any second within the last five days. The other options do not meet the requirements because they either have less than five days of continuous log retention or less than seven days of snapshot retention.
