Which action should be completed before updating Oracle Database software?
A. Verify CVMs have the required memory allocated.
B. Perform rolling reboots of the Oracle Database VMs.
C. Verify the Oracle OS version is supported on AHV.
D. Download the PSU from Oracle support.
Explanation:
Before updating Oracle Database software, you need to download the Patch Set Update (PSU) from Oracle
support. A PSU is a collection of critical and security patches for Oracle products. You need to have a valid
Oracle account and access to the My Oracle Support portal to download the PSU. You also need to check the
compatibility and prerequisites of the PSU before applying it to your Oracle Database software. NDB uses outof-
place patching for Oracle, which means you need to create a new software profile version with the patched
Oracle software and use it to update your existing databases.
Era allows custom metadata to be assigned to entities (clones, time machines, databases, and database servers) by using which component?
A. Tags
B. Notes
C. Text
D. Index
Explanation:
Nutanix Era allows custom metadata to be assigned to entities (clones, time machines, databases, and database
servers) by using Tags. 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.
How does NDB send notifications when alerts are generated?
A. SNMP
B. APIs
C. Pulse
D. Email
Explanation:
NDB sends notifications when alerts are generated via email. The email notifications can be configured to
send to one or more recipients, and can be customized to include the alert severity, category, description, and
resolution steps. The email notifications help to inform the database administrator and other stakeholders
about the status and issues of the NDB-managed databases and operations.
NDB does not send notifications via SNMP, APIs, or Pulse. SNMP is a protocol for collecting and organizing
information about managed devices on a network. APIs are interfaces for communicating and exchanging
data between different applications or systems. Pulse is a feature of the Nutanix cluster that collects and sends
diagnostic and usage data to Nutanix for analysis and support.
What step should be taken to make the profile available to all users:
A. Create an Access Control role with the Create Profile right and assign to all users.
B. Create an Access Control group with the desired users and grant it the Database Admin role.
C. Update the profile and set the status to Published.
D. Update the profile and set available state to All.
Explanation:
The correct answer is D because it allows the administrator to make the profile available to all users without
requiring any additional permissions or roles. A profile is a collection of settings that define how NDB
manages a database server or a database. By default, a profile is only available to the user who created it and
the Database Admin role. To make a profile available to all users, the administrator can update the profile and
set the available state to All. This will enable all users to view and use the profile for their database
operations. The other options are not correct because they either require additional steps or do not achieve the
desired outcome. Option A is not correct because creating an Access Control role with the Create Profile right
and assigning it to all users will only allow them to create their own profiles, not use the existing one. Option
B is not correct because creating an Access Control group with the desired users and granting it the Database
Admin role will only make the profile available to those users, not all users. Option C is not correct because
updating the profile and setting the status to Published will not change the availability of the profile, only the
state of the profile. A published profile is a profile that has been tested and verified by the administrator and is
ready for use. A draft profile is a profile that is still under development or testing and is not ready for
use.
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 shut down.
C. The patch must have been applied on Grid home only using NDB.
D. The database must be in read-only mode.
Explanation:
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.
What is the first step to add Time Machine (TM) data access to a Nutanix cluster?
A. Enable multi-cluster in NDB.
B. Disable multi-cluster in ND8.
C. Register the required Nutanix clusters in ND8.
D. Delete the TM data from the source database
Explanation:
To add Time Machine data access to a Nutanix cluster, the first step is to register the cluster in NDB. This
will allow NDB to discover and manage the databases and snapshots on the cluster. You can register multiple
Nutanix clusters in NDB using the Add Cluster option in the NDB settings page. You can also specify the
cluster role, such as source, target, or both, depending on the data access and replication needs. Enabling or
disabling multi-cluster in NDB is not the first step, as this is a global setting that affects the entire NDB
instance. Deleting the TM data from the source database is not the first step, as this will remove the data
protection and availability of the database.
