質問 # 109
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?
正解：A
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.

An administrator has received a request to clone a source production database to an existing development server.
Which two actions must be taken to complete this task?
正解：A、C
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.

An administrator needs to perform patching on a MongoDB server cluster within an NDB environment.
How should the administrator accomplish this task?
正解：A
解説：
The administrator should perform a rolling upgrade, applying the patch to the secondary members first, followed by the primary member, to accomplish the task of patching a MongoDB server cluster within an NDB environment. A rolling upgrade is a method of applying patches or updates to a cluster without downtime or interruption of service. The administrator can use the NDB patching feature to perform a rolling upgrade on a MongoDB server cluster, which consists of a primary member and one or more secondary members that form a replica set. The NDB patching feature allows the administrator to select the software profile version, the database parameters profile, and the network profile for the patching operation. The NDB patching feature also automates the steps of the rolling upgrade, such as:
Step 1: The administrator initiates the patching operation on the NDB instance, and selects the MongoDB server cluster to be patched.
Step 2: The NDB instance verifies the prerequisites and compatibility of the patching operation, and creates a pre-patch snapshot of the MongoDB server cluster.
Step 3: The NDB instance applies the patch to the first secondary member of the MongoDB server cluster, and waits for the patching to complete successfully.
Step 4: The NDB instance verifies the status and functionality of the patched secondary member, and repeats the patching process for the remaining secondary members of the MongoDB server cluster, one at a time.
Step 5: The NDB instance performs a failover of the primary member to one of the patched secondary members, and applies the patch to the original primary member.
Step 6: The NDB instance verifies the status and functionality of the patched primary member, and performs a failback of the primary member to the original primary member, if desired.
Step 7: The NDB instance creates a post-patch snapshot of the MongoDB server cluster, and completes the patching operation.
Performing a rolling upgrade, applying the patch to the secondary members first, followed by the primary member, is the recommended and best practice method of patching a MongoDB server cluster within an NDB environment, as it ensures the high availability, consistency, and performance of the MongoDB server cluster and the databases.
Performing a rolling upgrade, applying the patch to the primary member first, followed by the secondary members, is not a valid or feasible method of patching a MongoDB server cluster within an NDB environment, as it would cause downtime, data loss, and inconsistency of the MongoDB server cluster and the databases. Applying the patch to the primary member first would disrupt the replication and synchronization of the MongoDB server cluster, and would require manual intervention and recovery steps to restore the MongoDB server cluster to a functional state.
Applying the patch to all nodes at once is not a valid or feasible method of patching a MongoDB server cluster within an NDB environment, as it would cause downtime, data loss, and inconsistency of the MongoDB server cluster and the databases. Applying the patch to all nodes at once would require shutting down the entire MongoDB server cluster, and would expose the MongoDB server cluster and the databases to potential errors, failures, and corruption during the patching process.
Disabling the replica set while patching is not a valid or feasible method of patching a MongoDB server cluster within an NDB environment, as it would cause downtime, data loss, and inconsistency of the MongoDB server cluster and the databases. Disabling the replica set while patching would break the replication and synchronization of the MongoDB server cluster, and would require manual intervention and recovery steps to re-enable the replica set and restore the MongoDB server cluster to a functional state.

質問 # 112
An administrator needs to quickly restore a database to a previous point in time following an accidental data modification. The recovery must minimize downtime and avoid completely reinstalling the database.
Which NDB capability should be used?
正解：B
解説：
NDB Time Machine is the data-protection and recovery capability designed for this requirement. It combines application-consistent Nutanix storage snapshots with captured database transaction logs. The snapshot supplies a consistent recovery baseline, and the retained logs can be replayed to the requested time, enabling point-in-time recovery after an accidental modification while avoiding database reinstallation. This storage- efficient workflow is designed to reduce recovery time and minimize operational disruption. A Software Profile supplies standardized operating-system and database binaries for provisioning or patching; it does not preserve transactional recovery history. A Database Parameters Profile controls engine settings. Database cloning creates another usable copy and may use Time Machine data, but it is not the primary in-place recovery capability requested. Therefore, the correct answer is B, Time Machine. Nutanix Time Machine data protection
質問 # 113
Which statement best describes what happens when a 3rd-party backup tool is chosen to manage log backups for Microsoft SQL in NDB?
正解：C
解説：
NDB supports two modes of log backup management for Microsoft SQL databases: NDB-managed and 3rd- party managed. In the NDB-managed mode, NDB takes full control of the log backups and stores them in the Cerebro log location. In the 3rd-party managed mode, NDB allows the use of external backup tools to backup the logs from the database log destination. However, NDB still needs to capture the logs for its own operations, such as point-in-time recovery, clone refresh, and log catch-up. Therefore, NDB will periodically scan the database log destination and copy the logs to the Cerebro log location. This process requires that the log catch-up begins before the logs get backed up by the 3rd-party tool, otherwise NDB will miss some logs and the operations will fail. If the 3rd-party tool grants exclusive access to the logs, then NDB will not be able to capture them at all, and the operations will not be supported. References:
