The other options either perform the snapshot before the desired time or do not specify when the snapshot would occur. Please note that the exact answer might depend on the specific database system and its capabilities. Always refer to the database's documentation for the most accurate information.
質問 # 77
An administrator needs to roll back an Oracle patch on a database server VM using NDB.
What is required for this action to be successful?
- A. The database must be in read-only mode.
- B. The patch must have been applied using NDB.
- C. The database must be shut down.
- D. The patch must have been applied on Grid home only using NDB.
正解：B
解説：
To roll back an Oracle patch on a database server VM using NDB, the patch must have been applied using NDB in the first place. This is because NDB maintains a patch inventory and history for each database server VM and database that it manages. NDB uses this information to determine which patches can be rolled back and how to revert the changes made by the patch. If the patch was applied outside of NDB, NDB would not have the patch information and would not be able to roll back the patch.
Therefore, the patch must have been applied using NDB for the rollback action to be successful. The other options are not required for the rollback action. The database does not need to be shut down or in read-only mode, as NDB can perform the rollback operation online. The patch does not need to be applied on Grid home only, as NDB can roll back patches applied on both Grid home and Database home.

Multiple Databases as a Group with One Time Machine
Which statement is true regarding this chosen option?
- A. Point in Time Clones are not supported by Database Groups.
- B. PITR-based SLAs are not supported for database groups.
- C. PITR-based SLAs are supported for database groups containing mixed Recovery Model.
- D. PITR-based SLAs are not supported for database groups containing mixed Recovery Model
正解：D
解説：
Nutanix Database Automation (NCP-DB) introduces the concept of MS SQL Server database groups, which allows multiple databases running in the same database instance to be grouped as one Time Machine entity1. This applies to both single DB Server VM setups, standalone databases, as well as to Availability Group databases1. However, it does not support Point In Time Recovery (PITR)-based Service Level Agreements (SLAs) for database groups containing mixed Recovery Models. This means that if the databases within the group have different recovery models, PITR-based SLAs cannot be applied to the group as a whole.

質問 # 90
What is causing this issue?
- A. The VLAN is DHCP
- B. The VLAN is stretched
- C. The VLAN is IPAM
- D. The VLAN is static
正解：B
解説：
The correct answer is C because a stretched VLAN is a VLAN that spans across multiple Nutanix clusters, which may cause network conflicts or latency issues when starting the database server. Option A is incorrect because a DHCP VLAN is a VLAN that uses dynamic IP address allocation, which does not affect the database server startup. Option B is incorrect because a static VLAN is a VLAN that uses fixed IP address allocation, which also does not affect the database server startup. Option D is incorrect because IPAM is not a type of VLAN, but a feature of NDB that allows managing IP addresses for database servers and databases.
Reference: The following sources provide more information about the VLAN and IPAM concepts and configuration in NDB:

質問 # 91
An administrator has configured NDB HA across multiple Nutanix clusters.
Which failure scenario will require manual interaction for the recovery?
- A. More than one HA proxy VM is down.
- B. NDB Server process is down.
- C. One repository VM is down.
- D. More than one API Server VM is down.
正解：D
解説：
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.

質問 # 93
An administrator needs to deploy a cumulative update (CU) for SQL Server.
What steps would the administrator take to prepare this deployment with NDB?
- A. Create a new Software Profile version using the CU executable and publish that version.
- B. Create a new Software Profile using the CU executable and publish that profile.
- C. Apply the patch to the profile VM, then create a new Software Profile version using the profile VM as the source.
- D. Apply the patch to the profile VM, delete the existing Software Profile and create a new Software Profile using the profile VM as the source.
正解：C
解説：
The correct answer is C because it follows the recommended procedure for applying a CU to a SQL Server Software Profile in NDB. By applying the patch to the profile VM, the administrator ensures that the CU is compatible with the existing Software Profile settings and configuration. By creating a new Software Profile version, the administrator preserves the previous version of the Software Profile for rollback purposes and allows the new version to be tested and published. Option A is incorrect because it deletes the existing Software Profile, which may cause data loss and prevent rollback. Option B is incorrect because it does not apply the patch to the profile VM, which may result in errors or inconsistencies in the Software Profile. Option D is incorrect because it creates a new Software Profile instead of a new version, which may cause confusion and duplication.

An administrator needs to patch a PostgreSQL database server VM from version 13.4 to 13.8.
What is the first step within the NDB patching workflow to accomplish this task?
- A. Create a maintenance window and add this PostgreSQL server 13.8 to the queue.
- B. Create a Software Profile Version with PostgreSQL 13.8.
- C. Create a new Software Profile with PostgreSQL 13.8.
- D. Create a new Database Parameters profile for PostgreSQL server 13.8.
正解：B
解説：
NDB supports patching for PostgreSQL database instances. Patching for PostgreSQL is validated on VMs provisioned by NDB (greenfield deployments). To patch PostgreSQL database server VMs, you must create a software profile version by uploading the PostgreSQL update file in NDB. You can then use the PostgreSQL update to patch other database server VMs or provision a new database server VM with the updated software profile. The first step in the NDB patching workflow is to create a software profile version with the desired PostgreSQL version.

質問 # 96
Which two options can NDB leverage to refresh a database clone? (Choose two.)
- A. Cerebro logs
- B. Templates
- C. Snapshots
- D. Transaction logs
正解：C、D
解説：
NDB can leverage snapshots and transaction logs to refresh a database clone to the latest state of the source database. Snapshots are point-in-time copies of the database that are stored on the Nutanix cluster. Transaction logs are records of the changes made to the database after the snapshot was taken.
NDB can use either snapshots or transaction logs, or a combination of both, to refresh a database clone.
Cerebro logs and templates are not used for refreshing database clones. Cerebro logs are used for log catch-up operations, which are different from refresh operations. Templates are used for provisioning new databases, not for refreshing existing ones.

質問 # 97
How would an administrator enter the NDB command line to change the static IP address on the NDB VM?
- A. arithmos cli
- B. era
- C. cerebro_cli
- D. era-server
正解：C
解説：
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.
