An administrator needs to perform LCM upgrades on an AHV cluster registered with NDB. The cluster hosts NDB-provisioned database server VMs that are part of a database server cluster.
What should the administrator do to allow the DB Server VMs to stay available while the cluster is being upgraded?
- A. Unset VM-Host Affinity
- B. Set VM-Host Affinity
- C. Update Nutanix Cluster
- D. Remove Nutanix Cluster
Answer: B
Explanation:
The correct answer is B because setting VM-Host affinity ensures that the DB Server VMs are not migrated to another host during the LCM upgrade process. This way, the DB Server VMs can continue to serve the database requests without interruption. Option A is incorrect because updating the Nutanix cluster does not prevent the DB Server VMs from being moved to another host. Option C is incorrect because removing the Nutanix cluster from NDB will make the DB Server VMs unmanaged by NDB and lose the benefits of NDB features. Option D is incorrect because unsetting VM-Host affinity will allow the DB Server VMs to be migrated to another host during the LCM upgrade process, which may cause downtime or performance degradation.

NEW QUESTION # 55
How would an administrator enter the NDB command line to change the static IP address on the NDB VM?
- A. era-server
- B. cerebro_cli
- C. arithmos cli
- D. era
Answer: B
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 # 56
An administrator needs to increase storage for a MongoDB database provisioned using NDB. After launching the NDB CLI, the administrator begins with creating the input file for this operation.
Which parameter should the administrator include within the input file?
- A. extend_storage
- B. update
- C. data_percent
- D. database
Answer: A
Explanation:
To increase storage for a MongoDB database provisioned using NDB, the administrator needs to use the extend_storage parameter in the input file for the NDB CLI. This parameter specifies the amount of additional storage to be added to the database server VM in GB.
For example, if the current storage size is 100 GB and the administrator wants to increase it to 150 GB, the input file should contain the following line:
extend_storage: 50
The other parameters are not relevant for this operation. The update parameter is used to update the database software version, the database parameter is used to specify the database name, and the data_percent parameter is used to specify the percentage of data to be copied during a clone operation.
