NEW QUESTION # 47
Which response shows two ways to upgrade an NDB Server?

• A. One-click Upgrade and Offline Upgrade
• B. Upgrade and Manual Upgrade
• C. Out-of-Place Upgrade and In-place Upgrade
• D. One-click Upgrade and In-place Upgrade Auto

Answer: A

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.

NEW QUESTION # 49
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 1. Max 3
• B. Min 2, Max 4
• C. Min 2, Max 6
• D. Min 3, Max 5

Answer: B

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.

An administrator selected Bronze SLA for Era Time Machine during database registration.
Which two capabilities are supported by the Time Machine for this database? (Choose two,)

• A. Snapshots
• B. Cloning
• C. Log Catch up
• D. Provwonng

Answer: A,C

Explanation:
The Nutanix Era Time Machine provides various capabilities depending on the Service Level Agreement (SLA) selected during database registration1. For a database with a Bronze SLA, the Time Machine supports both "Log Catch up" and "Snapshots"2. "Log Catch up" allows the Time Machine to keep up with the latest changes in the database by capturing log data2. "Snapshots" are point-in-time copies of the database that can be used for recovery or cloning2.

NEW QUESTION # 51
What is the first step to add Time Machine (TM) data access to a Nutanix cluster?

• A. Enable multi-cluster in NDB.
• B. Register the required Nutanix clusters in ND8.
• C. Disable multi-cluster in ND8.
• D. Delete the TM data from the source database.

Answer: B

NEW QUESTION # 52
An administrator would like to use Era for Copy Data Management operations on an Availability Group (AG) database.
The AG database is hosted on replicas with different named instances, as shown below:
* SQLAGNI\EMR
* SQLAGN2\EMR
* SQLAGN3\DW
SQLAGN3\DW is running the Analytics service that needs real-time data.
How should the administrator register the database in Era?

• A. Register the database as a Standalone database,
• B. Register the database as an Availability database.
• C. Register the SQLAGN3 from AG cluster and register the database as Availability database,

Answer: B

Explanation:
According to the Nutanix Database Automation (NCP-DB) learning documents, when dealing with an Availability Group (AG) database, the database should be registered as an Availability database1. This is because the AG database is hosted on replicas with different named instances, and registering it as an Availability database allows for Copy Data Management operations to be performed across all instances.
This is particularly important when services such as the Analytics service running on SQLAGN3\DW require real-time data1.

NEW QUESTION # 53
A customer has NDB configured to create snapshots of their production databases every 4 hours.
A developer requires a copy of the current production data at 7:00am of each day.
What is the most efficient way to meet this requirement?

• A. Configure Time Machine to create a clone from a daily snapshot at 7:00am.
• B. Authorize the developer in RBAC to create clones as required.
• C. Run a script which creates a clone from the latest snapshot at 7:00am.
• D. Configure a done with a daily Data Refresh Schedule at 7:00am.

Answer: A

Explanation:
Time Machine is a feature of Nutanix Era that allows you to create and manage snapshots of your databases. You can use Time Machine to create clones from any snapshot, either manually or automatically. You can also configure Time Machine to create clones from snapshots based on a schedule, such as daily, weekly, or monthly. This way, you can ensure that your clones are always up to date with the latest data from your production databases. In this scenario, the most efficient way to meet the developer's requirement is to configure Time Machine to create a clone from a daily snapshot at
7:00am. This will save the developer's time and effort, as well as reduce the storage consumption by using the existing snapshots.

• D. From the dropdown menu choose Alerts Policies. Chose the Poliq to be modified and chose either Set Enabled or Set Disabled,

Answer: C

Explanation:
In Nutanix Era, an administrator can modify the Alert Severity level by navigating to the Alerts Policies from the dropdown menu. Once there, they can select the Policy that needs to be modified and set the desired severity level1. This allows the administrator to customize the alerts according to their requirements, ensuring that they are notified of the most critical events in their environment21.

NEW QUESTION # 55
An administrator would like to replicate database snapshots to remote Nutanix clusters.
What should the administrator do to manage Time Machine data availability across all registered Nutanix clusters in NDB?

• A. Select the snapshots & replicate them to each Nutanix cluster.
• B. Update the cluster's Data Access & select the remote cluster.
• C. Add Data Access to each Nutanix cluster and assign a DAM policy.
• D. Update the SLA on the Time Machine & schedule the remote replication.

Answer: C

Explanation:
To replicate database snapshots to remote Nutanix clusters, the administrator needs to add Data Access to each Nutanix cluster and assign a Data Availability Management (DAM) policy. Data Access is a feature of NDB that enables cross-cluster data mobility and protection. A DAM policy defines the replication frequency, retention period, and priority of the database snapshots across the clusters. By adding Data Access to each Nutanix cluster and assigning a DAM policy, the administrator can manage the Time Machine data availability across all registered Nutanix clusters in NDB.

NEW QUESTION # 56
An administrator needs to provide the least-privilege access to a newly-hired engineer whose task is to add new VLANs or IP Pools in NDB.
Which role should the administrator select to complete this task?

• A. Infrastructure Administrator
• B. Database Infrastructure Administrator
• C. Database Administrator
• D. Super Administrator

Answer: B

NEW QUESTION # 57
Which NDB feature collects logs and snapshots from databases?

• A. Time Machine
• B. Database Restore
• C. One-click Patching
• D. SLA

Answer: A

Explanation:
The correct answer is B because the Time Machine feature of NDB collects logs and snapshots from databases and stores them in a distributed file system. The Time Machine enables the administrator to protect, clone, and restore databases using the SLA policies and the NDB UI or API. The Time Machine also manages the replication of database snapshots in an NDB multicluster environment. The other options are not correct because they describe different features or functions of NDB. Option A is not correct because Database Restore is an operation that uses the Time Machine to restore a source database or a clone to a previous point in time. Option C is not correct because SLA is a policy that defines the frequency and retention of database snapshots and logs. Option D is not correct because One-click Patching is a feature that allows the administrator to test, publish, and apply database patches using the NDB UI or API.

Provision databases to a new container: This option allows you to provision a database to a new container. This is useful when you want to create a new isolated environment for your database1.

NEW QUESTION # 60
An administrator needs to add a stretched VLAN across two clusters in NDB Which two prerequisites should be met prior to completing this action? (Choose two.)

• A. VLAN must be IPAM.
• B. VLAN must be static.
• C. Both clusters must be registered in NDB.
• D. Nutanix Cluster Management must be enabled.

Answer: B,C

NEW QUESTION # 61
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 shut down.
• B. The patch must have been applied on Grid home only using NDB.
• C. The database must be in read-only mode.
• D. The patch must have been applied using NDB.

Answer: D

Explanation:
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.

NEW QUESTION # 62
An administrator needs to add a stretched VLAN across two clusters in NDB Which two prerequisites should be met prior to completing this action? (Choose two.)

• A. VLAN must be IPAM.
• B. VLAN must be static.
• C. Both clusters must be registered in NDB.
• D. Nutanix Cluster Management must be enabled.

Answer: B,C

Explanation:
A stretched VLAN is a virtual network that spans across multiple Nutanix clusters and allows the communication between VMs on different clusters using the same subnet. A stretched VLAN can be used to provide high availability and load balancing for NDB components, such as HAProxy VMs, that require a virtual IP address (VIP) to be accessible from any cluster. To add a stretched VLAN across two clusters in NDB, the administrator needs to meet two prerequisites: the VLAN must be static and both clusters must be registered in NDB. A static VLAN is a VLAN that is manually created and configured by the administrator, as opposed to an IPAM VLAN that is automatically created and managed by NDB. A static VLAN can be added to a stretched VLAN in NDB, while an IPAM VLAN cannot. Both clusters must be registered in NDB before adding a stretched VLAN, as NDB needs to have the information and access to the clusters and their networks. The administrator can register the clusters in NDB using the Prism Element details, agent network configuration, and storage container information. The other option, Nutanix Cluster Management, is not a prerequisite for adding a stretched VLAN in NDB. Nutanix Cluster Management is a feature that allows the administrator to manage multiple Nutanix clusters from a single NDB UI, such as creating or deleting clusters, adding or removing nodes, or performing cluster operations. Nutanix Cluster Management is not required for adding a stretched VLAN, as the VLANs are created and configured in Prism Element, not in NDB.
