質問 # 13
An administrator needs to take multiple snapshots per day and retain them for one week.
How should the administrator define and schedule the SLA?
- A. * Daily snapshot retention: 7 days
* Snapshots per Day: 2 - B. * Weekly snapshot retention: 1 week
* Daily Snapshot at: 2 - C. * Weekly snapshot retention: 1 week
* Snapshots per Day: 2 - D. * Daily snapshot retention: 7 days
* Daily snapshot at: 2
正解：A
解説：
The correct answer is D because it matches the requirement of taking multiple snapshots per day and retaining them for one week. Option A is incorrect because it only takes one snapshot per day, which is not enough for the administrator's need. Option B is incorrect because it only retains the snapshots for one week, which means the older snapshots will be deleted after seven days. Option C is incorrect because it only takes two snapshots per week, which is not frequent enough for the administrator's need.
Reference: The following sources provide more information about the SLA retention policies and how to create and modify them in NDB:

質問 # 14
Which action must an administrator take in Era Networks before using Era to provision a MSSQL AG cluster?
- A. A network that has a DHCP pool must be configured in Era.
- B. A network in each data center must be configured for Era.
- C. A that has a static pool managed by Era must be configured.
- D. A private network must be configured in Era for the heartbeat traffic.
正解：D
解説：
According to the Nutanix Database Automation (NCP-DB) learning documents, before using Era to provision a MSSQL AG cluster, an administrator must configure a private network in Era for the heartbeat traffic1. This is because the heartbeat traffic is crucial for maintaining the health and status of the MSSQL AG cluster. The heartbeat traffic is used by the nodes in the cluster to communicate with each other and check the status of the other nodes. If a node does not receive a heartbeat from another node within a certain time frame, it assumes that the other node has failed and takes appropriate action234.
質問 # 15
An administrator needs to restore a source database from a snapshot. The database shares the source volume with multiple other databases.
How does NDB handle this database restore operation?
- A. Copies the specific database files to the source volume
- B. Replaces source volume with specific db disks
- C. Replaces the source volume with the snapshot volume
- D. Copies all database files to the source volume
正解：A
解説：
The correct answer is A because NDB handles the database restore operation by copying the specific database files from the snapshot volume to the source volume, without affecting the other databases that share the same source volume. NDB uses a copy-on-write mechanism to create snapshots and clones, which means that only the changes made to the database files are stored in the snapshot or clone volume, while the original files are kept in the source volume. Therefore, when restoring a source database from a snapshot, NDB only needs to copy the specific database files that have been modified since the snapshot was taken, and overwrite them on the source volume. The other options are not correct because they either cause data loss or unnecessary data transfer. Option B is not correct because replacing the source volume with specific db disks would erase the other databases that share the same source volume, which is not desirable. Option C is not correct because replacing the source volume with the snapshot volume would also erase the other databases that share the same source volume, as well as any changes made to the source database after the snapshot was taken, which is not desirable. Option D is not correct because copying all database files to the source volume would be inefficient and unnecessary, as only the modified files need to be copied, and the other files are already present on the source volume.

質問 # 18
An administrator needs to increase storage for a MongoDB database provisioned using NDB. After launching the NDB CLI, the administrator begins with creating the input file for this operation.
Which parameter should the administrator include within the input file?
- A. database
- B. data_percent
- C. update
- D. extend_storage
正解：D
解説：
To increase storage for a MongoDB database provisioned using NDB, the administrator needs to use the extend_storage parameter in the input file for the NDB CLI. This parameter specifies the amount of additional storage to be added to the database server VM in GB.
For example, if the current storage size is 100 GB and the administrator wants to increase it to 150 GB, the input file should contain the following line:
extend_storage: 50
The other parameters are not relevant for this operation. The update parameter is used to update the database software version, the database parameter is used to specify the database name, and the data_percent parameter is used to specify the percentage of data to be copied during a clone operation.

An administrator needs to apply a minor version upgrade of the PostgreSQL software to an Era provisioned instance.
Which step should the administrator take before applying the patch?
- A. Migrate a new software profile.
- B. Create a new software profile.
- C. Put the database instance into maintenance mode.
- D. Go to the Software Profile Version widget and click update.
正解：B
解説：
Nutanix Database Service (NDB) supports automated minor version upgrades for PostgreSQL1. Before applying the patch, the administrator should create a new software profile2. This is because the software profile contains the database engine binaries and other software required to run the database engine2.
Therefore, to apply a minor version upgrade, a new software profile with the updated binaries needs to be created2. Once the new software profile is created, it can be used to patch the PostgreSQL database2.

What are two status values that can be set within the Alerts Dashboard? (Choose two.)
- A. Auto
- B. Resolved
- C. Data Resiliency
- D. Acknowledged
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.

質問 # 25
In an Oracle upgrade scenario using Era. if the source database is on a nor-Nutanix platform, is it possible to upgrade it with an Era workflow?
- A. Yes, only if the nan-Nutanix platform is big-endian platform,
- B. Yes, it is possible to upgrade database instance on a non-Nutanix platform.
- C. No, the database instaru:e must be Era managed to Be upgraded
- D. Yes, only if the nori-Nutanix platform is little-endian platform.
正解：C
解説：
According to the Nutanix Database Automation (NCP-DB) learning documents, Nutanix Era is a database management tool that automates and simplifies database operations, including provisioning, patching, upgrading, and more1. However, for a database to be managed by Era, it must be registered with Era1. This means that if a database is on a non-Nutanix platform, it cannot be directly upgraded using an Era workflow. It must first be migrated to a Nutanix platform and registered with Era before it can be managed and upgraded using Era1.
質問 # 26
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 containing mixed Recovery Model
- C. PITR-based SLAs are supported for database groups containing mixed Recovery Model.
- D. PITR-based SLAs are not supported for database groups.
正解：B
解説：
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.

質問 # 28
What is causing this issue?
- A. The VLAN is DHCP
- B. The VLAN is IPAM
- C. The VLAN is stretched
- D. The VLAN is static
正解：C
解説：
The correct answer is C because a stretched VLAN is a VLAN that spans across multiple Nutanix clusters, which may cause network conflicts or latency issues when starting the database server. Option A is incorrect because a DHCP VLAN is a VLAN that uses dynamic IP address allocation, which does not affect the database server startup. Option B is incorrect because a static VLAN is a VLAN that uses fixed IP address allocation, which also does not affect the database server startup. Option D is incorrect because IPAM is not a type of VLAN, but a feature of NDB that allows managing IP addresses for database servers and databases.
Reference: The following sources provide more information about the VLAN and IPAM concepts and configuration in NDB:

An administrator needs to create a custom PostgreSQL HA software profile.
Which software component manages the state of the cluster and handles failover?
- A. etcd
- B. HAProxy
- C. Patroni
- D. keepa lived
正解：C
解説：
NDB supports PostgreSQL HA software profiles for provisioning PostgreSQL databases with high availability. PostgreSQL HA software profiles consist of three components: etcd, HAProxy, and Patroni.
etcd is a distributed key-value store that provides a reliable way to store configuration data across a cluster of machines. etcd is used by Patroni to store and synchronize the cluster state and configuration.
HAProxy is a load balancer that distributes incoming requests to the PostgreSQL nodes. HAProxy is used to expose a single endpoint for database connections even as the roles of the individual nodes change.
Patroni is a template for PostgreSQL high availability. Patroni is responsible for managing the state of the cluster and handling failover. Patroni uses etcd as the distributed configuration store and relies on HAProxy for load balancing.
Therefore, the software component that manages the state of the cluster and handles failover is Patroni.
