1In a NetBackup 10.x environment, which component is responsible for managing the NetBackup catalog and coordinating all backup and restore operations?
A.Media server
B.Primary server
C.Storage server
D.NetBackup client
Explanation: The primary server (formerly called the master server) is the central component in a NetBackup domain. It hosts the NetBackup catalog, manages all backup policies and schedules, coordinates job activity across media servers and clients, and runs the NetBackup Web UI. Every NetBackup domain has exactly one primary server. Media servers handle data movement, storage servers provide storage targets, and clients are the systems being backed up.
2A NetBackup administrator wants to reduce backup traffic on the LAN by having clients send data directly to a SAN-attached storage device. Which media server transport mode should be configured?
A.Network Backup (NBD)
B.HotAdd transport
C.Fibre Channel (SAN Client)
D.Client Direct
Explanation: Client Direct (also known as SAN Client) allows a NetBackup client to write backup data directly to a Fibre Channel-attached storage device (such as an MSDP or disk storage unit) without routing traffic through the media server. This eliminates LAN backup traffic and significantly reduces the load on both the network and the media server. NBD (Network Backup) uses the LAN, HotAdd is a VMware-specific transport, and Fibre Channel by itself describes the fabric but is not a NetBackup transport mode designation.
3Which NetBackup policy attribute determines how long backup images are retained before they become eligible for expiration?
A.Checkpoint interval
B.Retention period
C.Schedule window
D.Maximum jobs per client
Explanation: The retention period attribute on a schedule (within a policy) specifies how long NetBackup retains backup images in the catalog. Once the retention period expires, the image record is removed from the catalog and the space on the storage device can be reclaimed. Checkpoint interval controls how often NetBackup saves a checkpoint for restartable jobs. Schedule window defines when a backup may run. Maximum jobs per client limits concurrency.
4An administrator configures a NetBackup policy with a Full backup schedule and a Cumulative Incremental schedule. What data does a Cumulative Incremental backup capture?
A.Only files changed since the last incremental backup of any type
B.All files changed since the last full backup
C.All files on the client regardless of change time
D.Only files that have never been backed up before
Explanation: A Cumulative Incremental backup captures all files that have changed since the last Full backup. This means each cumulative incremental image grows over time but restoring requires only the last full backup plus the most recent cumulative incremental. A Differential Incremental backup captures only changes since the last backup of any type (full or incremental), resulting in smaller individual backups but requiring more images for a full restore.
5A NetBackup administrator needs to ensure that backups of a critical Oracle database always run before other scheduled jobs. Which feature should be configured?
A.Policy priority
B.Storage unit multiplexing
C.Backup window overlap
D.Checkpoint restart
Explanation: Policy priority (also called job priority) is a numeric value assigned to a NetBackup policy that determines the order in which queued jobs are dispatched. A higher priority value means jobs from that policy are started before lower-priority jobs when resources are available. This ensures the critical Oracle backup runs first. Multiplexing interleaves multiple client streams on the same storage device, backup window overlap handles schedule conflicts, and checkpoint restart allows failed jobs to resume.
6Which NetBackup storage unit type uses disk-based deduplication technology on the media server to reduce the amount of data written to storage?
A.BasicDisk
B.Media Server Deduplication Pool (MSDP)
C.OpenStorage (OST) device
D.AdvancedDisk
Explanation: Media Server Deduplication Pool (MSDP) is NetBackup's built-in deduplication solution. The media server performs inline deduplication before writing data to the storage pool, comparing incoming data segments against a deduplication database (fingerprint catalog) and storing only unique segments. This significantly reduces storage consumption and can reduce backup data by 20:1 or more. BasicDisk and AdvancedDisk are disk storage units without deduplication. OST offloads deduplication to a third-party appliance or storage system.
7In a NetBackup MSDP environment, the deduplication fingerprint database and data containers are stored by default in which directory structure?
A./usr/openv/netbackup/db
B./var/openv/netbackup
C.The configured MSDP storage path (e.g., /msdp)
D./usr/openv/volmgr
Explanation: When an MSDP storage server and disk pool are configured, the administrator specifies a storage path (for example /msdp or /backup/msdp). NetBackup creates the fingerprint database (PureDisk catalog), data containers, and the spoold daemon working files under that configured path. The default NetBackup software directories (/usr/openv) contain binaries and operational logs, not MSDP data. The volmgr directory relates to volume and tape management.
8A NetBackup administrator wants to group multiple storage units of the same type so that jobs are distributed across them for load balancing. What should be configured?
A.Storage Lifecycle Policy (SLP)
B.Storage Unit Group
C.Disk pool with multiple volumes
D.MSDP replication group
Explanation: A Storage Unit Group allows an administrator to combine multiple storage units into a logical group. NetBackup can then assign jobs to storage units within the group using selection criteria such as round-robin (load balancing) or prioritized failover. This is distinct from a Storage Lifecycle Policy, which manages image duplication and replication operations. A disk pool is a collection of volumes within a single storage server, and MSDP replication groups pertain to deduplication replication between MSDP pools.
9Which NetBackup feature allows backup images to be automatically replicated to a remote NetBackup domain for disaster recovery purposes?
A.Storage Lifecycle Policy with a Replication operation
B.NetBackup Accelerator
C.MSDP-C cloud tiering
D.Catalog backup
Explanation: Auto Image Replication (AIR) is implemented through a Storage Lifecycle Policy (SLP) that includes a Replication operation. The SLP directs NetBackup to replicate deduplicated images from a source MSDP pool to an MSDP pool in a target NetBackup domain over a WAN. The target domain can then use these images for disaster recovery restores without needing the source domain to be online. Accelerator reduces backup time by sending only changed data. MSDP-C tiers data to cloud object storage. Catalog backup protects the primary server catalog.
10A NetBackup administrator notices that nightly full backups of a large file server take 8 hours. After enabling NetBackup Accelerator, subsequent full backup schedules complete in 45 minutes. What does Accelerator use to achieve this?
A.Synthetic full backup technology that reads data from existing images
B.Client-side changed-block tracking (CBT) to send only changed data
C.MSDP inline deduplication to skip sending duplicate segments
D.WAN optimization with variable-length deduplication
Explanation: NetBackup Accelerator works by maintaining a track log on the client that records which file system blocks have changed since the previous backup. On subsequent full or incremental backup schedules, only the changed blocks are sent to the media server. The media server then combines these changed blocks with unchanged data from a previous backup image stored in MSDP to construct a new full image. This results in dramatically shorter backup windows while still producing a standard full backup image. Synthetic full backups read from existing media server images, not the client.
