Which response shows two ways to upgrade an NDB Server?

  1. Out-of-Place Upgrade and In-place Upgrade
  2. One-click Upgrade and In-place Upgrade Auto
  3. Upgrade and Manual Upgrade
  4. One-click Upgrade and Offline Upgrade

Answer(s): D

Explanation:

There are two ways to upgrade an NDB Server: one-click upgrade and offline upgrade. One-click upgrade is the recommended method, as it automatically downloads and installs the latest NDB software version from the Nutanix portal. Offline upgrade is an alternative method, which requires you to manually download the NDB software bundle and upload it to the NDB Server VM. Both methods require you to have a valid Nutanix account and an internet connection.

What is purpose of the NDB Database Agent service?

  1. Temporarily stores the transaction logs.
  2. Hosts one or more source databases for the same time machine.
  3. Schedules and monitors the NDB-related operations.
  4. Contains an instance of the database engine software.

Answer(s): C

Explanation:

The correct answer is C because the NDB Database Agent service is responsible for scheduling and monitoring the NDB-related operations, such as provisioning, patching, cloning, and restoring databases. The NDB Database Agent service is deployed on the NDB server and on each of the database server VMs provisioned by NDB. It contains the tools required to perform each task and communicates with the NDB server through the NDB API. The other options are not correct because they describe different components or functions of the NDB solution. Option A is not correct because the transaction logs are not stored by the NDB Database Agent service, but by the NDB Time

Machine service, which is a distributed file system that stores the database snapshots and logs. Option B is not correct because the source databases are not hosted by the NDB Database Agent service, but by the database server VMs, which are virtual machines that contain an instance of the database engine software and the database files. Option D is not correct because the NDB Database Agent service does not contain an instance of the database engine software, but only the tools required to perform the NDB-related operations. The database engine software is installed on the database server VMs, which are provisioned by NDB using the profiles defined by the administrator.

An administrator needs to provide the least-privilege access to a newly-hired engineer whose task is to add new VLANs or IP Pools in NDB.
Which role should the administrator select to complete this task?

  1. Database Administrator
  2. Super Administrator
  3. Database Infrastructure Administrator
  4. Infrastructure Administrator

Answer(s): D

Explanation:

An Infrastructure Administrator is a role in NDB that has the permission to manage network and storage resources, such as VLANs, IP Pools, and Storage Containers. This role is suitable for the engineer who needs to add new VLANs or IP Pools in NDB. The other roles have either more or less privileges than required for this task. A Database Administrator can manage databases and database server VMs, but not network and storage resources. A Super Administrator can manage all aspects of NDB, but this is more than the least-privilege access needed. A Database Infrastructure Administrator can manage both databases and network and storage resources, but this is also more than the least- privilege access needed.

How can an administrator exclude Kernel patches for the Linux OS using the most efficient means?

  1. Define a pre-script to disable the repositories in the Patch Now advanced options
  2. Exclude the appropriate repositories on the VM prior to patching.
  3. Exclude the appropriate repositories on the VM and reboot prior to patching.
  4. Define a pre-script to disable the repositories in the Maintenance Window advanced options.

Answer(s): B

Explanation:

NDB supports Linux OS patching for database server VMs. Linux OS patching is performed by using the yum or apt package managers, depending on the Linux distribution. To exclude Kernel patches for the Linux OS, the administrator can disable or exclude the appropriate repositories on the VM prior to patching. This can be done by editing the yum.conf or apt.conf files, or by using the --disablerepo or --exclude options in the yum or apt commands. This way, the administrator can control which patches are applied to the VM without affecting other VMs or requiring additional scripts or reboots.
