Question 1NetWorker Architecture and Components

In a NetWorker data zone, which component owns the client configuration, media database, and resource database?

  1. The client daemon
  2. The NetWorker server Correct answer.
  3. The storage node
  4. The NetWorker management console host

Explanation

The NetWorker server is the central component of a data zone. It stores the resource database (configuration) and the media database (tracking of backup volumes), and it coordinates backup and recovery operations for all clients in that data zone.

Question 2NetWorker Architecture and Components

Which NetWorker process runs on the server and schedules and coordinates backup workflows across the data zone?

  1. nsrmmd
  2. nsrjobd Correct answer.
  3. nsrck
  4. nsrexecd

Explanation

nsrjobd is the NetWorker job daemon on the server that manages and schedules jobs and coordinates workflow execution. It is the service that tracks job state and dispatches work to the appropriate components.

Question 3NetWorker Architecture and Components

A company wants backups of a remote site's clients to write directly to tape drives attached to a host at that site, without streaming data back to the central server. Which NetWorker role provides this capability?

  1. A client-only installation
  2. A management console server
  3. A snapshot host
  4. A dedicated storage node Correct answer.

Explanation

A storage node is a host that owns backup devices and moves data directly to them, so remote clients can write locally rather than sending data across the WAN to the server. Using a storage node at the remote site keeps backup traffic local.

Question 4NetWorker Architecture and Components

Which NetWorker database records information about which backup volumes (media) contain a given save set?

  1. The jobs database
  2. The media database Correct answer.
  3. The resource database
  4. The client file index

Explanation

The media database tracks the backup volumes and the save sets stored on them, which is what NetWorker uses to locate data for recovery. The client file index, by contrast, tracks individual files within those save sets.

Question 5NetWorker Architecture and Components

What is the primary purpose of the client file index in a NetWorker data zone?

  1. To hold encryption keys for the data zone
  2. To store the schedule and retention policy definitions
  3. To track the individual files contained in each backup save set for a client Correct answer.
  4. To record the physical location of tape volumes in the library

Explanation

The client file index maintains a catalog of the files and directories captured in each save set, enabling file-level browsing and recovery. It is maintained per client and is distinct from the media database, which tracks volumes.

Question 6NetWorker Architecture and Components

Which NetWorker daemon on a client host receives and executes instructions from the NetWorker server during a backup?

  1. nsrexecd Correct answer.
  2. nsrjobd
  3. nsrd
  4. nsrmmd

Explanation

nsrexecd is the client-side agent that listens for requests from the NetWorker server and performs operations such as launching save and recover processes on the client. It is the process that must be running for a client to be backed up.

Question 7NetWorker Architecture and Components

A backup administrator notices that data is being read from a client but no data reaches the tape device. Which component is responsible for the actual data transfer to the backup device?

  1. The resource database
  2. The media multiplexor daemon (nsrmmd) Correct answer.
  3. The client file index
  4. The management console

Explanation

The media multiplexor daemon (nsrmmd) runs on the storage node that owns the device and performs the actual data movement to and from backup media. If it is not functioning, data read from the client will not be written to the device.

Question 8NetWorker Architecture and Components

Which statement best describes a NetWorker data zone?

  1. A group of clients that share a single backup schedule
  2. A single NetWorker server together with the clients, storage nodes, and devices it manages Correct answer.
  3. The set of volumes stored in a single tape library
  4. The collection of all NetWorker servers in an enterprise

Explanation

A data zone consists of one NetWorker server and all the clients, storage nodes, and devices that it manages. It is the fundamental administrative boundary in NetWorker; separate servers define separate data zones.

Question 9NetWorker Architecture and Components

Which NetWorker component provides a web-based interface for monitoring, reporting, and administering multiple NetWorker servers?

  1. nsradmin
  2. nsrwatch
  3. The client file index
  4. NetWorker Management Console Correct answer.

Explanation

The NetWorker Management Console (NMC) is the graphical, web-based administration and reporting interface that can manage one or more NetWorker servers. It communicates with the servers it administers to display and configure resources.

Question 10NetWorker Architecture and Components

An administrator needs to create and modify NetWorker configuration resources such as clients and pools from a command line. Which tool is designed for this?

  1. nsrwatch
  2. nsrck
  3. nsradmin Correct answer.
  4. mminfo

Explanation

nsradmin is the command-line utility for viewing and editing NetWorker resource database entries, including clients, pools, and devices. It provides direct access to the configuration resources that define the data zone.

Question 11NetWorker Architecture and Components

Which command-line utility would an administrator use to query the media database for save set and volume details?

  1. nsradmin
  2. nsrck
  3. mminfo Correct answer.
  4. nsrinfo

Explanation

mminfo queries the media database and reports on save sets, volumes, and related media information. It is the standard tool for verifying what data exists on which volumes.

Question 12NetWorker Architecture and Components

What does the NetWorker authentication service provide within a data zone?

  1. It schedules the nightly backup workflows
  2. It stores the client file index
  3. It authenticates users and issues tokens for access to NetWorker servers and the management console Correct answer.
  4. It encrypts all backup data written to tape

Explanation

The NetWorker authentication service (authc) validates user credentials and issues authentication tokens used to access NetWorker servers and management interfaces. It centralizes identity verification for the data zone's administrative access.

Question 13NetWorker Architecture and Components

Which NetWorker component is responsible for creating a point-in-time copy of a volume so that backup can occur with minimal impact on the source host?

  1. The media database
  2. The storage node
  3. The snapshot (block-based) backup feature Correct answer.
  4. The management console

Explanation

NetWorker's snapshot or block-based backup capability creates a point-in-time copy of a volume, allowing the backup to read from the snapshot instead of the live volume. This reduces the time the production volume is held and minimizes impact on the host.

Question 14NetWorker Architecture and Components

In NetWorker, what is the role of a pool?

  1. A logical grouping of backup volumes used to target and control where save sets are written Correct answer.
  2. A collection of server daemons
  3. A group of clients that share a schedule
  4. A set of storage nodes in a data zone

Explanation

A pool is a logical grouping of media (volumes) that determines which volumes a backup can write to. By associating clients and workflows with pools, administrators control which media receives which save sets.

Question 15NetWorker Architecture and Components

Which NetWorker concept organizes clients that share backup settings into a single administrative unit?

  1. Client group Correct answer.
  2. Pool
  3. Storage node
  4. Volume

Explanation

A client group is a collection of clients that share backup configuration, such as which workflows apply to them. Grouping clients simplifies applying policies and schedules across many hosts.

Question 16NetWorker Architecture and Components

An administrator wants backups of a high-priority group to run first and be retained longer than other backups. Which NetWorker objects are used to define this behavior?

  1. Workflows and policies with associated schedules and retention Correct answer.
  2. Storage nodes and devices
  3. Daemons and services
  4. Pools and volumes

Explanation

Policies, workflows, and their associated schedules and retention rules define when backups run and how long save sets are kept. Assigning a high-priority client group to a dedicated workflow lets those backups run and be retained as required.

Question 17NetWorker Architecture and Components

Which database must be intact for NetWorker to locate a save set on a specific volume during a recovery?

  1. The client file index only
  2. The resource database only
  3. The jobs database
  4. The media database Correct answer.

Explanation

The media database maps save sets to the volumes that hold them, so it is essential for locating data during recovery. The client file index helps find files within a save set, but volume location comes from the media database.

Question 18NetWorker Architecture and Components

What is the function of the NetWorker server daemon nsrd?

  1. It runs on clients to execute backup requests
  2. It provides the web-based reporting interface
  3. It is the main server daemon that manages the data zone and its services Correct answer.
  4. It writes data to tape devices

Explanation

nsrd is the primary NetWorker server daemon that manages the data zone, coordinating the server's services and resources. Other daemons and utilities interact with or are managed by nsrd on the server.

Question 19NetWorker Architecture and Components

A storage node is configured but backups fail to write to its devices. Which server-side resource must associate the devices with that storage node for data movement to succeed?

  1. The schedule resource
  2. The authentication token
  3. The client group resource
  4. The device resource and its storage node association Correct answer.

Explanation

Devices must be configured as resources and associated with the storage node that owns them so NetWorker knows which host performs data movement. Without that association, the server cannot direct writes to the correct storage node.

Question 20NetWorker Architecture and Components

Which NetWorker component tracks and displays the status of running and completed jobs?

  1. The client file index
  2. The authentication service
  3. The jobs database and job management functions of the server Correct answer.
  4. The media database

Explanation

NetWorker records job status and history in its jobs database and exposes job management functions on the server. Administrators use these to monitor running jobs and review completed ones.

Question 21NetWorker Architecture and Components

Which statement correctly distinguishes the resource database from the media database?

  1. The resource database stores configuration resources, while the media database stores volume and save set tracking Correct answer.
  2. The resource database stores file-level entries, while the media database stores schedules
  3. Both store identical configuration data for redundancy
  4. The media database stores client configuration, while the resource database stores volumes

Explanation

The resource database holds configuration resources such as clients, devices, pools, and policies. The media database separately tracks backup volumes and the save sets written to them, serving a different purpose.

Question 22NetWorker Architecture and Components

What is the purpose of the NetWorker client resource?

  1. To define a tape device owned by a storage node
  2. To define a pool of backup volumes
  3. To define an authentication token for administrators
  4. To define a host that the server protects and the settings used for its backups Correct answer.

Explanation

A client resource identifies a host to be protected and holds its backup settings, such as assigned groups, schedules, and save sets. It is the configuration object that ties a protected host into the data zone's policies.

Question 23NetWorker Architecture and Components

An administrator must verify which files are present in a specific save set before performing a file-level recovery. Which NetWorker facility should be queried?

  1. The resource database via nsradmin
  2. The media database via mminfo
  3. The jobs database via the console
  4. The client file index via nsrinfo Correct answer.

Explanation

The client file index records the files contained in each save set, and nsrinfo queries it to list those entries. This is the appropriate source for confirming file-level contents before a recovery.

Question 24NetWorker Architecture and Components

Which NetWorker feature allows a single server to protect clients across multiple geographic sites by placing data-movement components near the data?

  1. Distributed storage nodes within the data zone Correct answer.
  2. Multiple authentication services per client
  3. A separate management console per site
  4. A single global client file index shared across servers

Explanation

Storage nodes can be distributed across sites within one data zone so that data movement happens close to the clients and devices. The server retains central control while backups avoid crossing the WAN.

Question 25NetWorker Architecture and Components

Which component must be reachable by the NetWorker server for a client's backup to be initiated, assuming default configuration?

  1. The client's nsrexecd service Correct answer.
  2. The client's management console
  3. The client's media database
  4. The client's authentication service

Explanation

The NetWorker server contacts the client's nsrexecd service to initiate backup operations on that host. If nsrexecd is not running or reachable, the server cannot start the backup.

Question 26NetWorker Architecture and Components

An administrator wants to protect a NetWorker server's own bootstrap information so the server can be rebuilt after a total loss. Which NetWorker mechanism is designed for this purpose?

  1. The bootstrap save set written to a volume in the bootstrap pool Correct answer.
  2. The media database stored on the storage node
  3. The client file index of the NetWorker server host
  4. The lockbox stored in the authentication service

Explanation

NetWorker writes bootstrap save sets containing the server's resource database, media database and configuration so the server can be reconstructed after a disaster. Bootstrap backups are directed to the bootstrap pool and must be tracked and retained deliberately. The other databases are protected as part of this bootstrap, not as the dedicated rebuild mechanism.

Question 27NetWorker Architecture and Components

A backup administrator needs to know which NetWorker component holds the records that map each backed-up save set to the volume on which it resides. Which component performs this role?

  1. The client file index
  2. The resource database
  3. The media database Correct answer.
  4. The jobs database

Explanation

The media database (on the NetWorker server) tracks volumes and the save sets stored on them, which is what a recovery uses to find the correct volume. The client file index instead tracks file-level entries within save sets. Both are required for a complete recovery workflow but only the media database maps save sets to volumes.

Question 28NetWorker Architecture and Components

An administrator configures a new tape library attached to a host that is not the NetWorker server and wants backups of several clients to write directly to that library. Which configuration is required for this to work?

  1. Add the library host as a client resource and select the Data Domain option in its properties
  2. Configure the library as a clone target in the default pool and enable auto media management
  3. Register the library host in the authentication service and issue it a server certificate
  4. Create a storage node resource on the server and assign the devices to it, then associate the clients with that storage node Correct answer.

Explanation

A storage node is a host that owns devices and performs the data movement on behalf of the server; the server must have a storage node resource and the devices must be associated with it. Client resources then reference the storage node so their backups are directed to those devices. Without this association the server cannot use the remote library for those clients.

Question 29NetWorker Architecture and Components

An administrator must confirm that a scheduled backup group will start at the intended time and that its clients are eligible. Which NetWorker configuration object determines when a group's backups are initiated?

  1. The schedule resource assigned to the client
  2. The pool resource's retention period
  3. The client resource's backup command attribute
  4. The group resource's start time and interval attributes Correct answer.

Explanation

A group resource defines which clients are backed up together and when, through its start time and autostart or interval settings. The schedule resource controls level and retention behavior rather than the run time. The pool controls destination media, and the backup command controls how data is captured.

Question 30NetWorker Architecture and Components

During a recovery, NetWorker locates the save set in the media database but the volume is not mounted, and the required volume has been marked with a status that prevents it from being used for recovery. Which explanation best describes the effect of volume status on this recovery?

  1. The recovery fails until the volume is made available again, because NetWorker will not use a volume whose status forbids access Correct answer.
  2. The save set is unrecoverable because the media database record is deleted when a volume becomes unavailable
  3. The recovery is redirected automatically to any other volume in the same pool
  4. The recovery proceeds because NetWorker ignores volume status once a save set record exists

Explanation

Volume status governs whether NetWorker may read or write a volume; a status that forbids access blocks recovery even though the save set record exists. The administrator must change the volume status or mount the correct volume before the recovery can proceed. NetWorker does not silently substitute another volume or discard the media database record.

Question 31Installation and Initial Configuration

A NetWorker 19.x installation on Linux requires which component to be present on the host before the server package can be installed and configured?

  1. A pre-created NetWorker resource directory owned by the nsr user
  2. The NetWorker client package installed on at least one remote host
  3. A working Oracle database instance for the media database
  4. A supported version of the Java runtime for the NetWorker Management Console and auth service Correct answer.

Explanation

Current NetWorker server packages on Linux require a supported Java runtime because the NetWorker Management Console and the authentication service run on Java. The installer bundles or expects a compatible JRE, and installation fails if the required Java level is missing. The NetWorker resource directory is created by the installation itself rather than pre-created by the administrator.

Question 32Installation and Initial Configuration

During a Windows installation of the NetWorker server, which account type should be used to launch the installer so that services and registry entries can be created properly?

  1. A domain user with only backup operator rights
  2. The built-in Guest account with elevated file permissions
  3. A local standard user with write access to the install path
  4. An account that is a member of the local Administrators group Correct answer.

Explanation

Installing the NetWorker server on Windows registers services and writes protected registry keys, which requires administrative rights. The account used must be a member of the local Administrators group on the target host. Standard users, guests, and backup operators lack the privileges needed to create services.

Question 33Installation and Initial Configuration

When you install the NetWorker server software, which default location holds the resource files such as the client resource and the server configuration on Linux?

  1. /var/lib/networker
  2. /etc/emc/networker
  3. /nsr Correct answer.
  4. /opt/nsr

Explanation

On Linux and UNIX, NetWorker keeps its resource files and databases under the /nsr directory tree. Subdirectories such as /nsr/res hold the resource files that define clients, pools, and devices. Knowing this path matters for backups of the server itself and for troubleshooting configuration issues.

Question 34Installation and Initial Configuration

Which NetWorker package must be installed on a host whose only role is to send its file system data to the NetWorker server?

  1. The NetWorker server package
  2. The NetWorker client package Correct answer.
  3. The NetWorker Management Console package
  4. The NetWorker storage node package

Explanation

A host that only provides data for backup needs the NetWorker client package, which supplies the nsrexecd daemon and save/nsrfsra binaries. The server package and storage node package are only needed on hosts that manage or write backup data. Installing the client alone keeps the footprint small and licensing simple.

Question 35Installation and Initial Configuration

Which command is used on Linux to register a NetWorker client host with a NetWorker server after the client software is installed?

  1. nsrlic -a server
  2. nsrports -s server
  3. nsrclient -r server
  4. nsrclientd -a server Correct answer.

Explanation

The nsrclientd command with the -a option adds the specified NetWorker server to the client's server list, allowing the server to back up that client. This step is needed when the server was not specified during package installation. Without registration, the server cannot authenticate to the client daemon.

Question 36Installation and Initial Configuration

After installing the NetWorker server, which command is used to start the NetWorker daemons on a Linux host?

  1. nsrstartup
  2. systemctl start networker Correct answer.
  3. nsrd start
  4. service nsrexecd start

Explanation

On modern Linux distributions NetWorker is managed by systemd, so the service is started with systemctl start networker. The older nsrstartup command belonged to earlier releases and is not the current method. Starting only nsrexecd would leave the server daemon nsrd stopped.

Question 37Installation and Initial Configuration

Which NetWorker command-line utility is used to verify and repair the consistency of the media database after an unexpected server shutdown?

  1. nsrjb
  2. nsrim
  3. nsrck Correct answer.
  4. nsradmin

Explanation

nsrck checks and repairs the NetWorker media database and resource files after an unclean shutdown. Running it verifies consistency and can rebuild indexes if needed. The other utilities perform pruning, jukebox control, and resource administration respectively.

Question 38Installation and Initial Configuration

An administrator needs to change the range of TCP ports NetWorker uses so the traffic can pass through a firewall. Which command displays the current port range?

  1. nsrports Correct answer.
  2. nsrportcfg
  3. nsrconfig -p
  4. nsrnet -l

Explanation

The nsrports command displays and sets the service port and the range of dynamic ports NetWorker uses for client-server communication. Administrators use it to align the port range with firewall rules. The other commands listed are not NetWorker port configuration utilities.

Question 39Installation and Initial Configuration

Which file on a Linux NetWorker client records the servers that are authorized to back up that client?

  1. /nsr/res/nsrladb
  2. /nsr/res/nsr.res
  3. /nsr/res/servers Correct answer.
  4. /nsr/res/clients

Explanation

The servers file in the client's resource directory lists the NetWorker servers allowed to contact the client daemon. If a server is not listed there, backups from that server are rejected. The file is updated when you register a server with nsrclientd.

Question 40Installation and Initial Configuration

When you install NetWorker Management Console (NMC) on a host separate from the NetWorker server, which service must be running on the NMC host for the console to authenticate users?

  1. The NetWorker message agent
  2. The NetWorker jukebox service
  3. The NetWorker storage node service
  4. The NetWorker authentication service (authc) Correct answer.

Explanation

NMC relies on the NetWorker authentication service, authc, to authenticate and authorize console users. On a separate NMC host this service must be installed and running for logins to succeed. The storage node, message agent, and jukebox services do not provide console authentication.

Question 41Installation and Initial Configuration

Which NetWorker resource must be configured before any scheduled backup can run successfully on a newly installed server?

  1. A pool with at least one labeled volume and a client resource assigned to a group Correct answer.
  2. A directive that excludes all system files from the backup
  3. A clone pool that points to a remote tape library
  4. A storage node resource for every client in the data zone

Explanation

A scheduled backup needs a client resource assigned to a group, a pool that accepts the data, and at least one labeled volume in that pool. Without a writable volume the backup cannot start because there is no destination for the save sets. Cloning and exclusion directives are optional refinements, not prerequisites.

Question 42Installation and Initial Configuration

Which NetWorker resource defines the schedule that determines whether a backup is full, incremental, or skipped on a given day?

  1. The group resource
  2. The pool resource
  3. The policy resource
  4. The schedule resource in the policy Correct answer.

Explanation

In the NetWorker policy framework, schedules are defined within the policy and specify the backup level for each day of the week. Workflows reference these schedules to determine whether a given day triggers a full or incremental backup. Groups and pools control when and where backups run, not the level.

Question 43Installation and Initial Configuration

An administrator wants to label a new volume in a standalone tape device from the command line. Which NetWorker command performs this task?

  1. nsrmm -l Correct answer.
  2. nsrlabel -a
  3. nsrvol -n
  4. nsrjb -L

Explanation

The nsrmm command with the -l option labels and mounts a volume in a standalone device. It writes the volume label that NetWorker uses to identify the media. The nsrjb command is used for autochanger operations and nsrlabel is not a NetWorker utility.

Question 44Installation and Initial Configuration

Which NetWorker component must be authorized with a license before the server can accept backup data from clients?

  1. The Management Console
  2. The NetWorker server itself Correct answer.
  3. The authentication service
  4. Each individual client

Explanation

The NetWorker server requires a valid license, typically applied through the license resource, before it will run backups. Client licensing in modern releases is capacity-based and tied to the server rather than to individual client hosts. The console and authentication service do not consume backup licenses.

Question 45Installation and Initial Configuration

What is the purpose of running the NetWorker installation with the -s option specifying a server name on a client host?

  1. It configures the client to act as a remote console
  2. It pre-populates the client's server list with that server Correct answer.
  3. It sets the storage node that will receive the client's data
  4. It selects the schedule used for the client's backups

Explanation

Supplying a server name during client installation writes that server into the client's authorized server list. This lets the server contact the client daemon without a separate registration step. It does not choose a storage node, schedule, or console role.

Question 46Installation and Initial Configuration

Which default TCP port does the NetWorker server daemon nsrd listen on?

  1. 7938
  2. 8443
  3. 7937 Correct answer.
  4. 9090

Explanation

The NetWorker server daemon nsrd listens on TCP port 7937 by default. This port must be reachable from clients and consoles across firewalls. Port 7938 is used by the client daemon nsrexecd, and the other ports listed belong to unrelated services.

Question 47Installation and Initial Configuration

An administrator installs the NetWorker server but finds that the Management Console cannot be reached. Which service should be checked first on the NMC host?

  1. The gstd service Correct answer.
  2. The nsrexecd service
  3. The nsrjobd service
  4. The nsrmmd service

Explanation

The NetWorker Management Console web server is provided by the gstd service, which must be running for the console to be reachable in a browser. If gstd is stopped, the console page will not load even when the NetWorker server is healthy. The other services handle client communication, media movement, and job management.

Question 48Installation and Initial Configuration

Which NetWorker command is used to view and modify resources such as clients and pools from a text-based interface?

  1. nsrpolicy
  2. nsrwatch
  3. nsrls
  4. nsradmin Correct answer.

Explanation

nsradmin provides a command-line interface for viewing and editing NetWorker resources such as clients, pools, and devices. It supports both interactive and batch modes for scripted changes. The other commands display status, manage policy, or list information but do not edit resources.

Question 49Installation and Initial Configuration

After installing a NetWorker client, an administrator notices that backups fail with a message that the client is not in the server's list of authorized clients. What is the most likely cause?

  1. The client's schedule is set to skip
  2. The client resource was not created on the server or the client's server list does not include the server Correct answer.
  3. The storage node is offline
  4. The client's media database is corrupted

Explanation

Backups fail when the server has no client resource for the host or when the client does not list the server as authorized. Both sides must recognize each other for the backup to proceed. Media database corruption, an offline storage node, and a skip schedule produce different error messages.

Question 50Installation and Initial Configuration

Which statement about installing a NetWorker storage node on a host that is already a NetWorker client is accurate?

  1. A storage node cannot coexist with client software on the same host
  2. The storage node package replaces the client package and removes client functionality
  3. The storage node requires a separate server installation on the same host
  4. The storage node package can be added alongside the client software on the same host Correct answer.

Explanation

A NetWorker storage node can be installed on a host that already runs the client software, and the two components coexist. The storage node adds the ability to write backup data to devices attached to that host. It does not replace the client or require a separate server installation.
