Question #41
While adding Time Machine data access to a Nutanix cluster, when is a storage container mapping needed
- A . When the source database and NDB Server containers are different.
- B . When the source database and NDB VM are on the same container.
- C . When the source and destination database containers are different.
- D . When the source database and NDB provisioning container are the same.
Correct Answer: A
A
Explanation:
Time Machine data access is a feature of Nutanix Database Service (NDB) that allows you to access a point-in-time snapshot of a database without restoring it. To use this feature, you need to create a Data Access Management (DAM) policy that defines the access mode, the source database, the destination cluster, and the storage container mapping. The storage container mapping is needed when the source database and the NDB Server containers are different, because NDB needs to know where to store the metadata and the clone of the source database. If the source database and the NDB Server containers are the same, then NDB will use the same container for both the metadata and the clone.

Question #43
What is purpose of the NDB Database Agent service?
- A . Temporarily stores the transaction logs.
- B . Hosts one or more source databases for the same time machine.
- C . Schedules and monitors the NDB-related operations.
- D . Contains an instance of the database engine software.
Correct Answer: C
C
Explanation:
The correct answer is C because the NDB Database Agent service is responsible for scheduling and monitoring the NDB-related operations, such as provisioning, patching, cloning, and restoring databases. The NDB Database Agent service is deployed on the NDB server and on each of the database server VMs provisioned by NDB. It contains the tools required to perform each task and communicates with the NDB server through the NDB API. The other options are not correct because they describe different components or functions of the NDB solution. Option A is not correct because the transaction logs are not stored by the NDB Database Agent service, but by the NDB Time Machine service, which is a distributed file system that stores the database snapshots and logs. Option B is not correct because the source databases are not hosted by the NDB Database Agent service, but by the database server VMs, which are virtual machines that contain an instance of the database engine software and the database files. Option D is not correct because the NDB Database Agent service does not contain an instance of the database engine software, but only the tools required to perform the NDB-related operations. The database engine software is installed on the database server VMs, which are provisioned by NDB using the profiles defined by the administrator.

Question #44
Which response shows two ways to upgrade an NDB Server?
- A . Out-of-Place Upgrade and In-place Upgrade
- B . One-click Upgrade and In-place Upgrade Auto
- C . Upgrade and Manual Upgrade
- D . One-click Upgrade and Offline Upgrade
Correct Answer: D
D
Explanation:
There are two ways to upgrade an NDB Server: one-click upgrade and offline upgrade. One-click upgrade is the recommended method, as it automatically downloads and installs the latest NDB software version from the Nutanix portal. Offline upgrade is an alternative method, which requires you to manually download the NDB software bundle and upload it to the NDB Server VM. Both methods require you to have a valid Nutanix account and an internet connection.

Question #45
When preparing to provision multiple database server VMs, an administrator is tasked with configuring this set of VMs with the same number of cores per vCPU.
What is the easiest way for the administrator to accomplish this task?
- A . Create a Compute Profile and apply it to the VMs during provisioning.
- B . Update the VMs after provisioning and enter the changes to the vCPU cores.
- C . After provisioning the VMs. update the DEFAULT_OOB_COMPUTE Profile.
- D . Create a Windows Domain Profile that will synchronize the configurations.
Correct Answer: A
A
Explanation:
A Compute Profile is a template that defines the CPU, memory, and disk resources for a database server VM. By creating a Compute Profile with the desired number of cores per vCPU, the administrator can easily apply it to multiple VMs during provisioning, ensuring consistent and optimal performance. This also saves time and effort compared to updating the VMs individually or modifying the default profile after provisioning.

What is the best way achieve this requirement?
- A . Schedule an SLA policy to perform snapshot everyday at 9PM.
- B . Schedule an SLA policy that performs a snapshot at 99M and log catchup for every 15 min.
- C . Schedule e log catchup everyday at 9:30PM.
- D . Schedule an SLA policy to perform snapshot everyday at 9.30PM.
Correct Answer: D
D
Explanation:
. This is because it allows the database to be refreshed at the exact time specified (9:30 PM) with the most recent data. 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.
