Which statement best describes what happens when a 3rd-party backup tool is chosen to manage log backups for Microsoft SQL in NDB?
- A. Third-party backups vendors can continue to backup the archived logs from the database log destination. NDB will still be able to capture the logs, considering the log catch-up begins before the logs get backed up
- B. If exclusive log access is not granted to NDB, the Point-in-Time (PIT) recovery will be supported, but snapshot-based recovery of the databases is not supported.
- C. Third-party backups vendors can continue to backup the binary logs from the binary log location. NDB will still be able to capture the logs, considering the log catch-up begins before the logs get purged.
- D. If exclusive log access is not granted to NDB, the Point-in-Time (PIT) recovery will not be supported, but snapshot-based recovery of the databases is supported.
Answer: A
NEW QUESTION # 66
An administrator is trying to register a database server VM with NDB.
Which file types will prevent the registration from being successful if located in the C:\ drive?
- A. Database
- B. System
- C. Page
- D. Backup
Answer: C
Explanation:
Page files are temporary files that Windows uses to store data that does not fit in the physical memory.
Page files can interfere with the registration of a database server VM with NDB, as they can cause errors or performance issues. Therefore, page files should be located in a separate drive or partition from the C:\ drive, where the NDB agent and other files are installed. System, database, and backup files do not prevent the registration of a database server VM with NDB, as long as they are not corrupted or incompatible with the NDB requirements.

NEW QUESTION # 67
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. Set VM-Host Affinity
- B. Remove Nutanix Cluster
- C. Update Nutanix Cluster
- D. Unset VM-Host Affinity
Answer: A
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.

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 Instance parameter profiles and time machine SLA
- B. The user is able to manage software profiles, Network Profiles. database parameter profiles end Time Machine SLAs,
- C. The user is able to manage database 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: B
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 # 71
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, delete the existing Software Profile and create a new Software Profile using the profile VM as the source.
- 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. Create a new Software Profile version using the CU executable and publish that version.
Answer: C
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 # 74
An administrator is tasked with providing a Jr DBA with access to NBD with limited capabilities.
This user should only be able to:
* Provision Databases
* Provision Database Servers
* Create Ones
* Refresh Clones
* Patch Database Servers
How can the administrator complete this task?
- A. Clone the Database Admin role, and remove all but the desired privileges.
- B. Create a user for the Jr DBA, and assign only those privileges.
- C. Clone the Database Admin role, and add the desired privileges.
- D. Create a role with only those privileges, assign the role to the Jr DBA user.
Answer: D
Explanation:
The correct answer is B because it allows the administrator to create a custom role with the specific privileges that the Jr DBA user needs, and then assign that role to the user. This way, the administrator can control the access level of the Jr DBA user without affecting the existing roles or users in NDB.
Option A is incorrect because it involves cloning the Database Admin role, which has more privileges than the Jr DBA user requires, and then adding more privileges, which is unnecessary and redundant.
Option C is incorrect because it involves creating a user for the Jr DBA, but not assigning a role to the user, which means the user will not have any privileges in NDB. Option D is incorrect because it involves cloning the Database Admin role, which has more privileges than the Jr DBA user requires, and then removing some of the privileges, which is inefficient and risky.

NEW QUESTION # 77
When provisioning an PostgreSQL HA Instance, what are the minimum and maximum number of DB server VMs that can be deployed in a cluster?
- A. Min 2, Max 4
- B. Min 1. Max 3
- C. Min 2, Max 6
- D. Min 3, Max 5
Answer: A
Explanation:
When provisioning a PostgreSQL HA Instance using NDB, the minimum and maximum number of DB server VMs that can be deployed in a cluster are 2 and 4, respectively. A PostgreSQL HA Instance is a database instance that provides high availability and fault tolerance for PostgreSQL databases using the Patroni framework. Patroni is a Python-based tool that manages PostgreSQL configuration and performs automatic failover and switchover operations. Patroni relies on a distributed consensus store, such as etcd, Consul, or ZooKeeper, to store and synchronize the cluster state and leader information. NDB supports etcd as the consensus store for PostgreSQL HA Instances. NDB allows the administrator to provision PostgreSQL HA Instances with different sizes and configurations, such as small, medium, large, or custom. The size of the PostgreSQL HA Instance determines the number of DB server VMs, the number of etcd nodes, the CPU, memory, and disk resources, and the replication factor of the database.
The minimum number of DB server VMs for a PostgreSQL HA Instance is 2, which corresponds to a small size instance. This configuration provides one leader and one follower DB server VM, and one etcd node. The maximum number of DB server VMs for a PostgreSQL HA Instance is 4, which corresponds to a large size instance. This configuration provides one leader and three follower DB server VMs, and three etcd nodes. The other options are not valid for a PostgreSQL HA Instance, as they either do not provide enough redundancy or exceed the supported limit of DB server VMs.

NEW QUESTION # 78
While registering an Always on Availability Group database, an administrator selects the following option:
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 not supported for database groups containing mixed Recovery Model
- D. PITR-based SLAs are supported for database groups containing mixed Recovery Model.
Answer: C
Explanation:
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.

NEW QUESTION # 84
An administrator created a database clone that is scheduled for removal on the last day of the month.
A request has been received to keep the clone for an additional 14 days.
After selecting the desired clone, how should the administrator satisfy this task?
- A. Update the Removal schedule to the desired date.
- B. Update the Removal schedule to the end of the month.
- C. Select Update and modify the Removal schedule.
- D. Remove the Removal schedule, then add the desired removal schedule.
Answer: C
Explanation:
The Removal schedule is a feature of Nutanix Era that allows you to specify when a database clone will be automatically deleted. You can modify the Removal schedule of an existing clone by selecting the clone from the Clones page, clicking on the Update button, and changing the Removal schedule option to the desired date. This way, you can extend or shorten the lifespan of a clone as per your requirements. You do not need to remove the existing Removal schedule and add a new one, as this would be an unnecessary step. You also do not need to update the Removal schedule to the end of the month, as this would not meet the request of keeping the clone for an additional 14 days.
