NEW QUESTION # 307
An administrator has been asked to provision a new Oracle single instance database, but cannot proceed with the first step of the wizard. Which statement best describes the current situation?
Answer: C
Explanation:
When an administrator cannot proceed with the first step of the wizard to provision a new Oracle single instance database in NDB, the most likely reason is that a software profile for Oracle is missing. NDB requires a software profile (which defines the database version, patches, and configuration) to provision a database instance. Without a profile created from a reference VM or uploaded manually, the wizard cannot proceed, as it relies on this profile to configure the instance correctly.
* Option A (Time Machine is not configured) is incorrect because Time Machine is optional for backups and not required for initial provisioning.
* Option B (Software profile is missing) is correct as it is a mandatory prerequisite for provisioning any database instance.
* Option C (No remote clusters are configured) is incorrect because remote clusters are relevant for multi-cluster setups, not single instance provisioning.
* Option D (A snapshot must be taken on the original DB) is incorrect because snapshots are for protection, not a prerequisite for provisioning.
The administrator must create or import a software profile to resolve this issue.

NEW QUESTION # 308
An administrator needs to provision a PostgreSQL cluster instance with an external Load Balancer. Which software can be omitted on the Reference VM while creating the Software Profile?
Answer: B
Explanation:
When provisioning a PostgreSQL cluster instance with an external load balancer in NDB, the administrator creates a software profile from a reference VM. The reference VM typically includes software like Patroni (for HA management), HAProxy (for internal load balancing), keepalived (for high availability IP management), and etcd (for distributed configuration). Since an external load balancer is used, the internal HAProxy can be omitted from the reference VM. NDB will rely on the external load balancer to distribute traffic, eliminating the need for HAProxy in the software profile, while the other components remain essential for cluster management.
Option A (Patroni) is incorrect because Patroni is required for PostgreSQL HA management.
Option B (HAProxy) is correct as it can be omitted when an external load balancer is configured.
Option C (keepalived) is incorrect because keepalived is needed for HA IP failover.
Option D (etcd) is incorrect because etcd is necessary for distributed configuration in the cluster.
This adjustment streamlines the profile for external load balancer use.

NEW QUESTION # 309
An administrator needs to distribute NDB management plane components.
Which NDB HA VM needs to be deployed on the same L2 network?
Answer: C
Explanation:
NDB High Availability (HA) is a feature that ensures the availability and reliability of the NDB management plane components, such as the API Server, the Repository VMs, and the NDB Agents. To enable NDB HA, you need to deploy at least three HA Proxy VMs on the same L2 network as the NDB Server VM. The HA Proxy VMs act as load balancers and health monitors for the NDB management plane components, and they also provide a single endpoint for accessing the NDB APIs and UI. References:

NEW QUESTION # 310
A database administrator wants to clone an SQL database that has Transparent Data Encryption (TDE) enabled.
Which two steps must be taken on the target server for this clone to be successful? (Choose two.)
Answer: A,B
Explanation:
When cloning an SQL database with Transparent Data Encryption (TDE) enabled in NDB, the target server must handle the encryption keys to ensure the cloned database remains functional and secure. TDE uses a keystore (e.g., a bundle file containing the master key and certificate) to encrypt data. Two steps are required:
(1) The administrator must back up the keystore bundle file from the source database server VM and transfer it to the target server, ensuring the clone can decrypt the data. (2) After the clone is created, the administrator must run the post-clone command script, which configures the TDE keys on the target server, completes the encryption setup, and activates the cloned database.
* Option A (Backup the .cer and .pvk files from the source database server VM) is incorrect because TDE in SQL Server typically uses a keystore bundle, not separate .cer and .pvk files.
* Option B (Backup the keystore bundle file from the source database server VM) is correct as it ensures the encryption keys are available on the target.
* Option C (Run the pre-clone command script) is incorrect because pre-clone scripts are for preparation, not TDE-specific post-clone setup.
* Option D (Run the post-clone command script) is correct as it finalizes the TDE configuration on the target server.
These steps ensure a successful TDE-enabled clone.

NEW QUESTION # 311
For which database engine does Era support rolling back a patch using CLI?
Answer: A
Explanation:
Nutanix Era supports a variety of database engines, including Oracle, PostgreSQL, MySQL, and Microsoft SQL Server1. However, when it comes to rolling back a patch using the Command Line Interface (CLI), this feature is specifically supported for the Oracle database engine1. This allows for efficient validation of critical database updates and simplifies database rollback1. Please note that while Era does provide support for other database engines, the ability to rollback a patch using CLI is currently specific to Oracle1.
