Nutanix NCP-DB-6.5 Practice Test - Questions Answers, Page 10

The correct answer is A because the Windows Domain profile is the profile that includes information related to the SQL service startup account and the NDB worker service account. A Windows Domain profile is a collection of settings that define how NDB manages Windows-based database servers and databases. It contains the following information:

The domain name and credentials to join the database server VMs to the domain

The SQL service startup account and password to run the SQL Server service on the database server VMs

The NDB worker service account and password to run the NDB Database Agent service on the database server VMs

The SQL Server authentication mode to use for the databases

By using a Windows Domain profile, the administrator can simplify the database provisioning process by applying the same settings to multiple database server VMs and databases, without having to manually enter them each time. The other options are not correct because they describe different types of profiles that do not include information related to the SQL service startup account and the NDB worker service account. Option B is not correct because the Network profile is a profile that defines the network settings for the database server VMs, such as the IP address, subnet mask, gateway, DNS, and VLAN. Option C is not correct because the Database Parameter profile is a profile that defines the database parameters for the databases, such as the memory, CPU, storage, and performance settings. Option D is not correct because the Software profile is a profile that defines the software settings for the database server VMs and databases, such as the database engine version, edition, and features.Reference:Nutanix Database Management & Automation (NDMA) course,Nutanix Certified Professional - Database Automation (NCP-DB) certification,Nutanix NCP-DB Certification Exam Syllabus and Study Guide,Nutanix Database Services: Database modernization with Era - Now available

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.

Ports 3205 and 3260 are important when working with Era because they must be open on the Era server and all Controller VMs (CVMs) to facilitate iSCSI connections1.Specifically, port 3205 is used for iSCSI redirection2.Please be careful of routing iSCSI traffic, as it could impact performance2.

In the context of Nutanix Era, the term ''Brownfield Database'' is used to refer to an existing database that is registered with Era1.This process allows Era to bring Database as a Service (DBaaS) capabilities to your existing database2.It's important to note that before you register a database with Era, certain prerequisites must be met3.

Nutanix Era can be upgraded using the Offline Upgrade and One-click Upgrade methods. The Offline Upgrade method involves manually downloading the software update and applying it to the Era instance.The One-click Upgrade method allows you to upgrade Era directly from the Era management console with a single click, provided that the Era instance has internet connectivity and can reach the Nutanix software update portal1.

The Nutanix Era platform provides a feature called Time Machine, which is designed to manage the lifecycle of database copies and clones1. When a new table is added to the source database, the administrator should perform a Log Catch-up using the source database's Time Machine.This action ensures that the Time Machine captures the latest state of the source database, including the newly added table1. After performing the Log Catch-up, the administrator should refresh the clone database.The refresh operation updates the clone with the latest state captured by the Time Machine, thereby publishing the new table to the clone1.

The size of a database Time Machine in Nutanix Era is defined by the size of all snapshots and/or transaction logs maintained by Era1.The Time Machine leverages Nutanix's efficient snapshot technology to capture the state of the database at different points in time1.These snapshots, along with transaction logs that record changes between snapshots, constitute the data maintained by the Time Machine1.Therefore, the size of the Time Machine is determined by the total size of these snapshots and transaction logs1.

The Alerts dashboard in Nutanix displays alert messages with three severity levels: Critical, Warning, and Info1.These severity levels help users understand the importance and urgency of each alert, allowing them to prioritize their responses accordingly1.

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.
