NEW QUESTION # 77
Within NDB, an administrator needs to register a PostgreSQL database server VM with a database.
Where should the database data and log files be located in order to successfully complete this task?
- A. On the same mount point
- B. On a separate mount point
- C. On the same disk as the binary installation
- D. On the same disk as the operating system
Answer: B
Explanation:
To register a PostgreSQL database server VM with a database on NDB, the database data and log files must be located on a separate mount point from the operating system and the binary installation. This is because NDB uses the mount point as the identifier for the database server VM and the database. If the data and log files are on the same mount point as the operating system or the binary installation, NDB will not be able to recognize them as a valid database server VM or database. Therefore, the administrator should create a separate mount point for the data and log files and specify it during the registration process.

NEW QUESTION # 78
Which statement is true regarding the NDB alert retention feature?
- A. NDB supports retention at the registered cluster.
- B. NDB supports retention at the grouped policy.
- C. NDB supports retention at the individual policy.
- D. NDB supports alert retention globally.
Answer: D
Explanation:
The NDB alert retention feature allows the database administrator to configure the duration for which the NDB alerts are stored and displayed in the NDB instance. The NDB alert retention feature supports alert retention globally, meaning that the same retention period applies to all the alerts generated by the NDB instance, regardless of the source cluster, policy, or operation. The database administrator can set the alert retention period from 1 day to 365 days, or choose to retain the alerts indefinitely. The NDB alert retention feature helps to manage the storage space and the visibility of the NDB alerts.
The NDB alert retention feature does not support retention at the individual policy, grouped policy, or registered cluster level. The NDB alert retention feature applies to all the alerts uniformly, and does not allow the database administrator to specify different retention periods for different policies or clusters.

An administrator needs to change the maximum number of database connections during the cloning workflow.
Which Era profile should the administrator choose?
- A. Network
- B. Compute
- C. Database Parameters
Answer: C
Explanation:
In Nutanix Database Automation (NCP-DB), the Database Parameters profile is used to manage database-specific settings, including the maximum number of database connections. This profile would be the appropriate choice when an administrator needs to change these settings during the cloning workflow1.
NEW QUESTION # 80
An administrator enables NDB Multi-Cluster on Cluster A. Cluster B is then registered with NDB.
What are the different NDB Service VMs present in each Nutanix cluster?
- A. Cluster A: 1 NDB Agent
Cluster B: 1 NDB Server - B. Cluster A: 1 NDB Agent
Cluster B: 1 NDB Server, 1 NDB Agent - C. Cluster A: 1 NDB Server
Cluster B: 1 NDB Agent - D. Cluster A: 1 NDB Server, 1 NDB Agent
Cluster B: 1 NDB Agent
Answer: D
Explanation:
NDB Multi-Cluster is a feature that allows multiple Nutanix clusters to share a common NDB service for database management and automation. NDB service consists of two components: NDB Server and NDB Agent. NDB Server is the central component that provides the web UI, REST API, and database orchestration logic. NDB Agent is the component that runs on each Nutanix cluster and communicates with the NDB Server to perform database operations.
When NDB Multi-Cluster is enabled on Cluster A, it becomes the primary cluster that hosts the NDB Server VM. Cluster B, which is registered with NDB, becomes a secondary cluster that hosts only the NDB Agent VM. Therefore, Cluster A has both NDB Server and NDB Agent, while Cluster B has only NDB Agent. This configuration allows Cluster B to leverage the NDB service running on Cluster A for database management and automation.

NEW QUESTION # 81
Which statement describes a user in Era with the Database Infrastructure Admin role?
- A. The user is able to manage software profiles, Network Profiles. database parameter profiles end Time Machine SLAs,
- B. The user is able to manage database profiles, Network Profiles, database Instance parameter profiles and time machine SLA
- C. The user is able to manage software profiles, Network Profiles. database Instance parameter profiles and time machine SLA
- D. The user is able to manage software profiles, database parameter profiles and SLAs
Answer: A
Explanation:
The size of a database Time Machine in Nutanix Era is defined by the size of all snapshots and/or transaction logs maintained by Era1. The Time Machine leverages Nutanix's efficient snapshot technology to capture the state of the database at different points in time1. These snapshots, along with transaction logs that record changes between snapshots, constitute the data maintained by the Time Machine1. Therefore, the size of the Time Machine is determined by the total size of these snapshots and transaction logs1.
NEW QUESTION # 82
Refer to the exhibit.
An administrator attempts to provision their first clustered database environment with NDB. The operation fails with the Operation Error shown in the exhibit.
Which database engine was being deployed during this operation?
- A. Microsoft SQL
- B. Oracle
- C. PostgreSQL
- D. MySQL
Answer: B
NEW QUESTION # 83
Which action must an administrator take in Era Networks before using Era to provision a MSSQL AG cluster?
- A. A private network must be configured in Era for the heartbeat traffic.
- B. A network that has a DHCP pool must be configured in Era.
- C. A that has a static pool managed by Era must be configured.
- D. A network in each data center must be configured for Era.
Answer: A
Explanation:
According to the Nutanix Database Automation (NCP-DB) learning documents, before using Era to provision a MSSQL AG cluster, an administrator must configure a private network in Era for the heartbeat traffic1. This is because the heartbeat traffic is crucial for maintaining the health and status of the MSSQL AG cluster. The heartbeat traffic is used by the nodes in the cluster to communicate with each other and check the status of the other nodes. If a node does not receive a heartbeat from another node within a certain time frame, it assumes that the other node has failed and takes appropriate action234.
NEW QUESTION # 84
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. Apply the patch to the profile VM, then create a new Software Profile version using the profile VM as the source.
- B. Create a new Software Profile version using the CU executable and publish that version.
- C. 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.
- D. Create a new Software Profile using the CU executable and publish that profile.
Answer: A
Explanation:
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.

NEW QUESTION # 89
Where should an administrator perform an upgrade within the Era management interface?
- A. Operations > Current Recent
- B. Profiles Software
- C. Administration > Maintenance
- D. Alerts
Answer: C
Explanation:
In the Nutanix Era management interface, an administrator should perform an upgrade under the Administration > Maintenance section1. As part of the upgrade process, the Era server is upgraded first, followed by all the Era cluster agents and database server agents in parallel1. The Dashboard displays the current version and an option to upgrade the Era server to a latest version when a new version is available for upgrade1. This ensures that the Nutanix Era environment is always up-to-date with the latest features and security updates1.
NEW QUESTION # 90
Refer to the exhibit.
An administrator, whose accounts are shown in the exhibit, is trying to add a new database admin as a local user to NDB, but is unable to complete the task.
What is most likely the cause of the issue?
- A. Only users in the domain admins group can create local users.
- B. An email address is required for the Super Admin account.
- C. The administrator is logged in with the Database Admin account.
- D. The administrator is logged in with the Super Admin account.
Answer: C
Explanation:
Based on the exhibit, the administrator is logged in with the Database Admin account ([email protected]), which does not have the permission to create local users on NDB. Only the Super Admin account (bsmith) has this permission, as indicated by the User type column. Therefore, the administrator needs to log out and log in again with the Super Admin account to add a new database admin as a local user to NDB.
