An administrator needs to provision a 3-node MSSQL Server AG with the following configuration:
* Two database server VMS including the primary replica on a local site
* A third database server VM on a remote site
How many IP addresses will the network at each site require?
- A. I Cluster VIP end I Listener IP on the local site
1 Listener IP on the local site
2 IPs in the local site and I on the remote site for the database server nodes - B. 2 Cluster VIP and 1 listener IP on the local site
- C. Cluster VIP end I Listener IP on the local site
1 Cluster VIP and 1 Listener IP on the remote site
2 IPs in the local site and 1 on the remote site for the database server nodes - D. 1 Cluster VIP and 1 listener IP on the remote site
2 IPs in the local site and 1 on the remote site for the database server nodes
1 Cluster VIP on the local site
1 Cluster VIP and 1 Listener IP on the remote site
2 IPs in the local site and 1 on the remote site for the database server nodes
正解：C
解説：
The correct answer is D.
When setting up a 3-node MSSQL Server AG with two database server VMs on a local site and a third database server VM on a remote site, the network at each site will require the following IP addresses:
1 Cluster VIP and 1 Listener IP on the local site123.
1 Cluster VIP and 1 Listener IP on the remote site123.
2 IPs in the local site and 1 on the remote site for the database server nodes123.
This configuration ensures that each node in the cluster has a unique IP address, and each cluster and listener also has a unique IP address. This is necessary for the proper functioning of the cluster and to ensure that all nodes can communicate with each other and with clients123.
質問 # 45
An administrator needs to maintain five days of time-travel capability to any second, plus an additional seven days of discrete recovery at a daily interval.
How should the administrator define the Frequency and retention on the SLA?
- A. * Daily snapshot retention (days): 7
* Continuous log retention (days): 5 - B. * Continuous log retention (days): 7
* Daily snapshot retention (days): 5 - C. * Continuous log retention (days): 5
* Weekly snapshot retention (weeks): 1 - D. * Weekly snapshot retention (weeks): 1
* Continuous log retention (days): 7
正解：A
解説：
The correct answer is D because it meets the requirements of maintaining five days of time-travel capability to any second and an additional seven days of discrete recovery at a daily interval. Continuous log retention allows the administrator to restore the database to any point in time within the specified number of days, while snapshot retention allows the administrator to restore the database to a specific point in time at a fixed interval. Therefore, by setting the daily snapshot retention to 7 days, the administrator can ensure that there is a discrete recovery point for each day of the week. By setting the continuous log retention to 5 days, the administrator can ensure that there is a time-travel capability to any second within the last five days. The other options do not meet the requirements because they either have less than five days of continuous log retention or less than seven days of snapshot retention.

質問 # 46
An administrator needs to provision a database for test purposes with a data protection policy that minimizes storage usage.
How should the administrator best complete this task?
- A. Disable the SLA for this database during provisioning.
- B. Select the built-in NONE SLA that is configured for no snapshot or log backup.
- C. Create a SLA that only leverages zero-byte snapshots.
- D. Create a custom SLA for this database that only retains 1 day of snapshots and bogs.
正解：B
解説：
Nutanix Database Automation (NCP-DB) allows administrators to manage Service Level Agreements (SLAs) for databases. These SLAs define the data protection policies for databases. In this case, to minimize storage usage for a test database, the administrator should select the built-in NONE SLA. This SLA is configured for no snapshot or log backup, thus minimizing storage usage1.
質問 # 47
What are two status values that can be set within the Alerts Dashboard? (Choose two.)
- A. Data Resiliency
- B. Acknowledged
- C. Auto
- D. Resolved
正解：B、D
解説：
The correct answer is B and D because these are the two status values that can be set within the Alerts Dashboard in NDB. Resolved means that the alert has been fixed and no longer requires attention.
Acknowledged means that the alert has been seen and is being worked on. Option A is incorrect because Auto is not a status value, but a mode that automatically resolves alerts based on predefined rules. Option C is incorrect because Data Resiliency is not a status value, but a feature that ensures the availability and integrity of the data in NDB.
Reference: The following sources provide more information about the Alerts Dashboard and its status values in NDB:

質問 # 50
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 patch must have been applied using NDB.
- B. The database must be in read-only mode.
- C. The patch must have been applied on Grid home only using NDB.
- D. The database must be shut down.
正解：A
解説：
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.

Which two actions must be taken to complete this task?
- A. The development server must be registered by Era in order to receive the clone.
- B. The development server must have the IP and credentials provided during cloning.
- C. The development server must be authorized for the database Time Machine.
- D. The development server must be registered by Era and authorized to host clones from the Time Machine.
正解：A、B
解説：
According to the Nutanix Database Automation (NCP-DB) Learning documents12, to clone a source production database to an existing development server, the following actions must be taken:
A) The development server must be registered by Era in order to receive the clone1. This is because Nutanix Era is a database management tool that manages the lifecycle of databases and their copies.
Registering the development server with Era allows it to manage the database on that server.
D) The development server must have the IP and credentials provided during cloning2. This is necessary for Era to access the development server and perform the cloning operation. The IP address and credentials are used to establish a connection to the development server. Without these details, Era would not be able to access the server and perform the cloning operation.

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

質問 # 59
An administrator was asked to change the snapshot schedule for a given database. The administrator discovered that the time machine is in a paused state.
How should the administrator change the schedule?
- A. Clone the database and define an appropriate schedule for the clone.
- B. Select Time Machine: Under actions Resume the Time Machine and then Update to define an appropriate schedule.
- C. Clone the Time Machine and define an appropriate schedule for the clone.
- D. Select the Time Machine; under Action select Update end define an appropriate schedule.
正解：D
解説：
According to the Nutanix Database Automation (NCP-DB) learning documents, an administrator can change the snapshot schedule for a given database by selecting the Time Machine, then under Action, select Update and define an appropriate schedule1. This is because the Time Machine in Nutanix Era allows you to specify the number of backups or snapshots the time machine should take, the time of day it takes those snapshots, and the day of the week it takes weekly or monthly backups1. These options help you build a complete schedule of time machine capture operations1. Even if the Time Machine is in a paused state, the administrator can still update the schedule1. Cloning the Time Machine or the database is not necessary for changing the snapshot schedule1.
質問 # 60
For an NDB offline upgrade, which NDB CLI command should be used to upload the upgrade bundle?
- A. path=path_to_upgrade_bundle upgrade bundle
- B. path=path_to_upgrade_bundle
- C. upload upgrade_bundle path=path_to_upgrade_bundle
- D. upgrade upload_bundle path=path_to_upgrade_bundle upload bundle
正解：C
解説：
For an NDB offline upgrade, you need to download the upgrade bundle from the Nutanix Support Portal and copy it to the NDB server. Then, you need to use the NDB CLI command upload upgrade_bundle with the path parameter to specify the location of the upgrade bundle file. This command will upload the upgrade bundle to the NDB server and verify its integrity. After uploading the upgrade bundle, you can use the upgrade command to perform the upgrade.

質問 # 61
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. Nutanix Cluster Management must be enabled.
- D. Both clusters must be registered in NDB.
正解：B、D
解説：
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.

質問 # 62
Where should an administrator perform an upgrade within the Era management interface?
- A. Profiles Software
- B. Operations > Current Recent
- C. Administration > Maintenance
- D. Alerts
正解：C
解説：
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.
