質問 # 115
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 # 116
An administrator needs to deploy a cumulative update (CU) for SQL Server.
What steps would the administrator take to prepare this deployment with NDB?
- A. Create a new Software Profile using the CU executable and publish that profile.
- B. Apply the patch to the profile VM, then create a new Software Profile version using the profile VM as the source.
- C. Apply the patch to the profile VM, delete the existing Software Profile and create a new Software Profile using the profile VM as the source.
- D. Create a new Software Profile version using the CU executable and publishthatversion.
正解：B
解説：
The correct answer is C because it follows the recommended procedure for applying a CU to a SQL Server Software Profile in NDB. By applying the patch to the profile VM, the administrator ensures that the CU is compatible with the existing Software Profile settings and configuration. By creating a new Software Profile version, the administrator preserves the previous version of the Software Profile for rollback purposes and allows the new version to be tested and published. Option A is incorrect because it deletes the existing Software Profile, which may cause data loss and prevent rollback. Option B is incorrect because it does not apply the patch to the profile VM, which may result in errors or inconsistencies in the Software Profile. Option D is incorrect because it creates a new Software Profile instead of a new version, which may cause confusion and duplication.

質問 # 117
Refer to the exhibit.
An administrator, whose accounts are shown in the exhibit, is trying to add a new database admin as a local user to NDB, but is unable to complete the task.
What is most likely the cause of the issue?
- A. Only users in the domain admins group can create local users.
- B. An email address is required for the Super Admin account.
- C. The administrator is logged in with the Database Admin account.
- D. The administrator is logged in with the Super Admin account.
正解：C
解説：
Based on the exhibit, the administrator is logged in with the Database Admin account ([email protected]), which does not have the permission to create local users on NDB. Only the Super Admin account (bsmith) has this permission, as indicated by the User type column. Therefore, the administrator needs to log out and log in again with the Super Admin account to add a new database admin as a local user to NDB.

An administrator wants to test the provisioning capabilities after a new NDB deployment. Which database instance would be available to accomplish this task?
- A. PostgreSQL
- B. MSSQL Server
- C. Oracle DB
- D. MongoDB
正解：A
解説：
After a new NDB deployment, the administrator can test the provisioning capabilities using a database instance that is fully supported and readily configurable out of the box. PostgreSQL is the most suitable option because it is one of the core database engines supported by NDB from the initial deployment, with built-in provisioning templates and HA capabilities. NDB provides a streamlined process to provision PostgreSQL instances, making it an ideal choice for testing provisioning workflows, including VM creation, storage allocation, and network configuration.
Other options may require additional setup or licensing:
* B. Oracle DB: Requires specific licensing and additional configuration, not typically available for initial testing.
* C. MSSQL Server: Supported but may need Microsoft licensing and setup, less immediate than PostgreSQL.
* D. MongoDB: Supported but less commonly used for initial testing due to its NoSQL nature and additional configuration needs.
Thus, the verified answer is A, reflecting PostgreSQL's accessibility for testing.

質問 # 120
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?
- A. The development server must be authorized for the database Time Machine.
- B. The development server must have the IP and credentials provided during cloning.
- C. The development server must be registered by Era and authorized to host clones from the Time Machine.
- D. The development server must be registered by Era in order to receive the clone.
正解：B、D
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 # 121
For supported Linux based database VM's managed by NDB, how would an administrator keep software profiles updated for provisioning new database VMs?
- A. Associate the newly provisioned database VMs with a maintenance window so they are keep updated.
- B. Apply patches to a database VM for each supported database engine, then create a new software profile version for each supported database VM for each one using the updated database VM as the source.
- C. Create a Maintenance window under the policy menu, then under Database VM, add the database VMs to that maintenance window and check both Database and Operating system updates.
- D. In the Administrator menu drop down, go the Maintenance tab and choose Download Upgrade
正解：B
解説：
For supported Linux-based database VMs managed by NDB, keeping software profiles updated for provisioning new database VMs requires a structured process. The administrator must first apply the necessary patches (e.g., OS updates and database engine patches) to an existing database VM for each supported database engine (e.g., PostgreSQL, Oracle). Then, a new software profile version must be created using the updated VM as the source. This new version captures the patched configuration and can be used to provision new VMs, ensuring they are deployed with the latest updates.
* Option A (Create a Maintenance window under the policy menu, then under Database VM, add the database VMs to that maintenance window and check both Database and Operating system updates) is incorrect because a Maintenance Window schedules updates for existing VMs, not for updating software profiles for new provisions.
* Option B (Apply patches to a database VM for each supported database engine, then create a new software profile version for each supported database VM for each one using the updated database VM as the source) is correct as it follows the standard NDB process for profile updates.
* Option C (Associate the newly provisioned database VMs with a maintenance window so they are kept updated) is incorrect because this applies to ongoing maintenance, not initial profile updates for provisioning.
* Option D (In the Administrator menu drop down, go the Maintenance tab and choose Download Upgrade) is incorrect because downloading upgrades is part of the patch process, not the profile creation step.
This method ensures new VMs are provisioned with the latest software configurations.

質問 # 122
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 on Grid home only using NDB.
- B. The database must be shut down.
- C. The database must be in read-only mode.
- D. The patch must have been applied using NDB.
正解：D
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. References:

質問 # 123
Before registering a database server VM to NDB, what should an administrator use to verify all required software and configuration dependencies?
- A. NCC
- B. LCM
- C. Upgrade Software
- D. Prerequisites script
正解：D
解説：
Before registering a database server VM to NDB, an administrator must verify that all required software (e.g., database engine, OS dependencies) and configuration settings (e.g., WinRM for Windows, SSH for Linux) are in place. NDB provides a prerequisites script, which can be run on the target VM to check these dependencies automatically. This script ensures compatibility and readiness, reducing registration failures.
* Option A (LCM - Lifecycle Manager) is incorrect because LCM is used for cluster upgrades, not VM prerequisite checks.
* Option B (Upgrade Software) is incorrect as it applies to updating existing software, not initial dependency verification.
* Option C (Prerequisites script) is correct as it is the designated tool for pre-registration validation.
* Option D (NCC - Nutanix Cluster Check) is incorrect because NCC checks cluster health, not VM- specific software dependencies.

Tags are a component of Nutanix Era that allows users to assign custom metadata to various entities, enhancing the ability to organize, search, and manage these entities within the Era platform1.
質問 # 129
An administrator needs to register a Nutanix cluster with NDB.
Which condition requires the administrator to create a manual storage mapping between the remote container and NDB provisioning container?
- A. Disaster Recovery Network Segmentation is enabled on the cluster.
- B. Nutanix Database Service High Availability is enabled on the cluster.
- C. DB VMs are stored in the NDB Server or NDB Provisioning container.
- D. NDB Server container and NDB Provisioning container are separate.
正解：D
解説：
When registering a Nutanix cluster with NDB, a manual storage mapping between the remote container and the NDB provisioning container is required if the NDB Server container and NDB Provisioning container are separate. This separation occurs when the storage containers used by the NDB server (for its own operations) and the provisioning container (for database VMs) are distinct, either due to multi-cluster setups or custom configurations. Manual mapping ensures NDB can correctly allocate storage resources and manage database provisioning across these containers.
Other conditions do not necessitate manual mapping:
* B. Disaster Recovery Network Segmentation is enabled on the cluster: This affects networking, not storage mapping.
* C. Nutanix Database Service High Availability is enabled on the cluster: HA configurations handle replication, not container mapping.
* D. DB VMs are stored in the NDB Server or NDB Provisioning container: This is a typical setup and does not require manual mapping unless containers differ.
Thus, the verified answer is A, addressing storage container separation.

質問 # 130
A NDB non-administrative user wants to provision an Oracle database leveraging a Software Profile that the administrator created. What must the administrator do to ensure that this user has access to the Oracle Software Profile?
- A. Promote the Software Profile to Published to be available by other NDB users.
- B. Replicate the Software Profile to other Nutanix clusters for all users to access.
- C. Ensure that the Software Profile has been properly versioned to the latest release of Oracle.
- D. Ensure that specified users have access to the Software Profile using Access Control.
正解：A
解説：
To allow a non-administrative NDB user to provision an Oracle database using a Software Profile created by an administrator, the administrator must promote the Software Profile to Published. In NDB, Software Profiles define the database software version and configuration (e.g., Oracle binaries). By default, a newly created profile is in a draft or private state. Promoting it to "Published" makes it available for use by other NDB users, including non-administrative ones, within the access control framework. This ensures the profile is validated and accessible without requiring individual user assignments.
Other options are incorrect:
* A. Ensure that specified users have access to the Software Profile using Access Control: Access Control manages user permissions but does not make the profile available unless it is published.
* B. Replicate the Software Profile to other Nutanix clusters: Replication is for HA or disaster recovery, not user access.
* C. Ensure that the Software Profile has been properly versioned to the latest release of Oracle:
Versioning ensures compatibility but does not grant user access.
Thus, the verified answer is D, aligning with NDB's profile management workflow.

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 # 133
An administrator needs to provision multiple database clones from the same source database for different purposes, such as QA and Test/Development. To avoid resource starving, the administrator wants to differentiate VM resources for each department.
What is the most efficient way to accomplish this task?
- A. Use a VM Template for each department.
- B. Leverage NCM Self Service to deploy database clones.
- C. Generate a playbook to resize database VMs when released.
- D. Create multiple Compute profiles.
正解：D
解説：
An administrator needs to provision multiple database clones from the same source database for different purposes (e.g., QA and Test/Development) while avoiding resource starvation by differentiating VM resources for each department. The most efficient way to achieve this is by creating multiple Compute profiles in NDB. Compute profiles define CPU, memory, and other resource allocations for VMs, allowing the administrator to tailor resource limits (e.g., higher resources for QA, lower for Development) and apply them during clone provisioning. This approach is built into NDB, ensuring consistent resource management without manual adjustments.
* Option A (Create multiple Compute profiles) is correct as it provides a scalable and efficient way to allocate resources per department.
* Option B (Leverage NCM Self Service to deploy database clones) is incorrect because Nutanix Cluster Management (NCM) Self Service is for end-user provisioning, not resource differentiation.
* Option C (Use a VM Template for each department) is incorrect because VM templates are less flexible and not natively integrated with NDB clone provisioning.
* Option D (Generate a playbook to resize database VMs when released) is incorrect because playbooks are for automation, not initial resource allocation, and resizing post-provisioning is less efficient.
This method optimizes resource use across departments.

質問 # 134
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. PITR-based SLAs are not supported for database groups containing mixed Recovery Model
- B. PITR-based SLAs are not supported for database groups.
- C. Point in Time Clones are not supported by Database Groups.
- D. PITR-based SLAs are supported for database groups containing mixed Recovery Model.
正解：A
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 # 135
How would an administrator enter the NDB command line to change the static IP address on the NDB VM?
- A. cerebro_cli
- B. era
- C. era-server
- D. arithmos cli
正解：A
解説：
To change the static IP address on the NDB VM, an administrator would need to enter the NDB command line using the cerebro_cli command. The cerebro_cli command is used to access the Cerebro service, which is responsible for managing the NDB instance and its components. The cerebro_cli command can be run from the NDB VM or from any other VM that has network connectivity to the NDB VM. The cerebro_cli command has various subcommands and options to perform different tasks, such as changing the IP address, hostname, password, or certificate of the NDB VM. To change the static IP address, the administrator would need to use the cerebro_cli network update subcommand with the appropriate parameters, such as the new IP address, netmask, gateway, and DNS servers. The cerebro_cli network update subcommand also requires the administrator to provide the current password of the NDB VM for authentication. After changing the IP address, the administrator would need to restart the NDB VM for the changes to take effect. References:

質問 # 136
Which port should be opened to ensure the NDB server, NDB agent, and NDB database agent can communicate with the registered cluster via REST API calls?
- A. 0
- B. 1
- C. 2
- D. 3
正解：A
解説：
To ensure the NDB server, NDB agent, and NDB database agent can communicate with the registered cluster via REST API calls, port 2009 must be opened. This port is used by NDB components to facilitate RESTful communication with the Nutanix cluster (e.g., Prism Element or Prism Central) for operations such as provisioning, monitoring, and management. Proper firewall configuration to allow traffic on this port is a prerequisite for NDB's integration with the cluster.
Other options are incorrect:
* B. 3205: Not a standard NDB port; used for other Nutanix services.
* C. 3260: Associated with iSCSI, not REST API communication.
* D. 9440: Used for Prism Element's HTTPS management interface, not NDB-specific REST calls.
Thus, the verified answer is A, reflecting NDB's REST API requirements.

質問 # 137
An organization has NDB HA enabled across multiple Nutanix clusters.
If two clusters are using ESXi and one cluster is using AHV, which additional component is necessary to support cross-hypervisor compatibility?
- A. Stretched VLANs for all nodes
- B. VirtlO
- C. Nutanix Prism Central
- D. NGT
正解：C
解説：
In an NDB high availability (HA) environment spanning multiple Nutanix clusters, with two clusters running VMware ESXi and one running Nutanix AHV, cross-hypervisor compatibility becomes essential to manage the heterogeneous environment effectively. Nutanix Prism Central is the centralized management platform that provides a unified interface and orchestration capabilities across multiple clusters, regardless of the underlying hypervisor (ESXi or AHV). For NDB HA to function seamlessly across these clusters, Prism Central is required to coordinate cluster operations, manage resources, and ensure consistent policy enforcement, including VM placement, failover, and database management tasks. It abstracts the differences between hypervisors, enabling NDB to operate in a mixed environment.
* Option A (Stretched VLANs for all nodes) is incorrect because stretched VLANs address network connectivity, not hypervisor compatibility or NDB HA management.
* Option B (NGT - Nutanix Guest Tools) is incorrect as NGT enhances guest VM functionality (e.g., drivers, backups) but does not facilitate cross-hypervisor orchestration for NDB HA.
* Option C (Nutanix Prism Central) is correct because it provides the necessary multi-cluster management and compatibility layer for NDB HA across ESXi and AHV.
* Option D (VirtlO) is incorrect as VirtIO refers to paravirtualized drivers for VMs, not a component for NDB HA or cross-hypervisor support.
Prism Central's role ensures that NDB can manage database workloads across diverse hypervisor platforms efficiently.
