A junior administrator is tasked with performing the initial installation of a NetWorker Server on a Windows Server machine. After running the installer and accepting the defaults, they are unable to connect using the NetWorker Management Console. A senior administrator points out that the Windows Firewall is enabled. Which process must be allowed through the firewall for core NetWorker server communication, including connections from the NMC?
Show answer details
Correct answer: C
The
nsrd.exeprocess is the main NetWorker server daemon. It listens on the service and connection ports (typically 7937, 7938, and a range) for incoming requests from clients, storage nodes, and administrative consoles like NMC. Allowingnsrd.exethrough the firewall is essential for the NetWorker datazone to function. - 2
A manufacturing company is using a CloudBoost appliance to back up several legacy systems. The administrator needs to verify the health and status of the CloudBoost appliance, including its connection to the cloud provider and the current deduplication ratio. Where would the administrator find this information?
Show answer details
Correct answer: C
The CloudBoost appliance is managed through its own dedicated web-based user interface, known as the CloudBoost Management Console. This console provides a dashboard with detailed information about the appliance's health, storage utilization, deduplication statistics, replication status, and connectivity to the configured cloud storage.

When deploying a NetWorker vProxy using the OVA template in vCenter, the deployment wizard prompts for several configuration details. Which piece of information is configured during this initial OVA deployment process?
Show answer details
Correct answer: C
The vCenter 'Deploy OVF Template' wizard for the vProxy specifically includes a 'Customize template' section where you must provide the core networking information for the appliance itself. This includes its static IP address, subnet mask, default gateway, and DNS servers. The connection to the NetWorker server is configured later after the appliance is powered on.

A backup consultant is explaining the NetWorker architecture to a new client. They need to describe the component responsible for listening for backup requests on a client machine and starting the
saveprocess. Which NetWorker daemon performs this specific function on every NetWorker client?Show answer details
Correct answer: B
The
nsrexecd(NetWorker execution daemon) runs on every NetWorker client. Its primary role is to listen for requests from the NetWorker server. When the server initiates a scheduled backup for that client,nsrexecdreceives the request and is responsible for launching thesavecommand to begin the backup process. - 5
Company Background:
An e-commerce company, ShopFast, uses a hybrid cloud model with an on-premises data center and a significant presence in Google Cloud Platform (GCP). Their primary NetWorker server is on-premises. They have deployed several production database servers as virtual machines in GCP.Current Situation:
ShopFast needs to back up their GCP virtual machines using their existing on-premises NetWorker infrastructure. They have established a secure, high-bandwidth interconnect between their data center and GCP. However, they are concerned about the cost and complexity of routing large amounts of backup data from the cloud back to their on-premises backup storage.Requirements & Constraints:
- Backups of GCP VMs must be stored within GCP to avoid data egress charges and leverage cloud-native storage.
- The backup solution must provide efficient, deduplicated storage for the backups within GCP.
- The on-premises NetWorker server must remain the central point of management for all backup and recovery operations.
- The deployment in GCP should be as automated and streamlined as possible.
Question:
What is the most appropriate solution for ShopFast to protect their GCP VMs while meeting all their requirements?Show answer details
Correct answer: C
This is the ideal architecture for in-cloud backup managed by an on-premises server. Deploying DDVE in GCP provides a highly efficient, deduplicated backup target that keeps data within the cloud. By installing clients on the GCP VMs and configuring one as a storage node, backups can be written directly to the DDVE instance. The on-premises NetWorker server manages the entire process, meeting all requirements for in-cloud storage, efficiency, and centralized management.

A financial institution is upgrading its NetWorker environment from version 19.8 to 19.10. The environment includes a primary NetWorker server, two storage nodes, and the NetWorker Management Console (NMC) on a separate host. To ensure a smooth transition and minimize downtime, what is the mandatory sequence for upgrading these components?
Show answer details
Correct answer: B
The correct upgrade order is critical for maintaining compatibility and control within the NetWorker datazone. The NetWorker Server must be upgraded first as it is the central controller. Following the server, the Storage Nodes should be upgraded to ensure they can communicate correctly with the newly upgraded server. The NetWorker Management Console (NMC) Server should be upgraded last, as it must be at the same or a higher version than the NetWorker Server it manages.

A large media company uses NetWorker to protect its assets. To offload long-term archives, they have configured a Cloud Tier device pointing to an AWS S3 bucket. An administrator observes that data movement to the cloud is much slower than expected. Investigation reveals the data is being tiered from a PowerProtect DD appliance. Which configuration change would most significantly improve the data movement performance to the Cloud Tier device?
Show answer details
Correct answer: C
When moving data from a PowerProtect DD appliance to a Cloud Tier device, the data must first be rehydrated by the DD appliance, then sent to the NetWorker storage node, and finally transferred to the cloud. This rehydration process is a major performance bottleneck. By configuring the data movement policy to read data directly from the DD appliance in its deduplicated format and send it to the cloud, the rehydration step is bypassed, dramatically improving performance.

During the deployment of a NetWorker vProxy appliance in a secure vSphere environment, an administrator is tasked with selecting the most efficient data transport mode that minimizes impact on the production LAN. The environment consists of ESXi hosts connected to a Fibre Channel SAN where the datastores reside. The vProxy will be deployed as a VM on one of these hosts. Which transport mode should be prioritized in the vProxy configuration?
Show answer details
Correct answer: D
The SAN transport mode allows the vProxy to directly read VM data from the Fibre Channel SAN storage, completely bypassing the ESXi host's management network and the production LAN. This provides the highest performance and has the least impact on the network, which meets the specified requirements. HotAdd is also efficient but involves attaching the VM's disk to the vProxy, whereas SAN mode provides direct data path access.

A system administrator is reviewing the processes running on a NetWorker server and notices that the
nsrmmdbddaemon is consuming a high amount of CPU resources. Which two functions are the primary responsibility of this specific daemon? (Select TWO)Show answer details
Correct answer: B, D
The nsrmmdbd (NetWorker media management database daemon) is responsible for managing the media database, which includes tracking all backup volumes, their locations, and status.
The nsrmmdbd also records detailed metadata for every save set, such as its creation time, level, size, and which volume it resides on. This information is crucial for browsable recoveries.

True or False: When deploying NetWorker Virtual Edition (NVE) in a public cloud provider like AWS or Azure, it is a mandatory prerequisite to pre-configure a PowerProtect DD Virtual Edition (DDVE) instance to act as the primary backup target.
Show answer details
Correct answer: B
While using a DDVE instance is a common and recommended architecture for performance and deduplication, it is not a mandatory prerequisite. NVE can be configured to use other backup targets, including cloud object storage directly via a Cloud Tier device or Advanced File Type Devices (AFTD) on cloud-based block storage.
