Free Practice Questions for EMC D-NWR-DY-01 Exam

For backing up an AIX system to cloud object storage with maximum performance, the recommended approach is to use a CloudBoost appliance. CloudBoost provides optimized deduplication, compression, and encryption, enabling efficient and secure backups from legacy platforms like AIX directly to cloud storage.

The “Optimized for Performance” backup optimization mode is only supported on Data Domain systems running DDOS 6.0.0.30 (or later) - and if you’re on the 5.7 release train, you must be at least at DDOS 5.7.1. Attempting to enable Performance mode on a DD appliance at plain DDOS 5.7.0 will cause the configuration to fail (or fall back to Capacity mode) with a warning in the logs.

The vProxy appliance supports three transport modes - HotAdd, NBD, and NBDSSL - but Dell EMC strongly recommends using HotAdd for the fastest, most efficient VM backups. HotAdd mounts target VM disks directly into the proxy VM’s address space, avoiding network hops, reducing latency, and offloading I/O from the ESXi management network

When Client Direct is enabled on a client resource, the NetWorker client pushes its deduplicated data stream straight to the AFTD (or DD Boost) device - bypassing the NetWorker storage node entirely - while still sending all control and metadata updates (client file index entries, media database operations, etc.) back to the NetWorker server so it can track and catalog the backup.

To recover a virtual machine from a save set stored on Dell Cloud Tier, the save set must first be manually staged (mounted) back to a DD Boost device. Cloud Tier data cannot be accessed directly for recovery; it must be recalled to a local DD Boost device to complete the operation.

The commandnslookup queries the specified DNS server to resolve the fully qualified domain name (FQDN) of the NetWorker Virtual Edition (NVE) into its corresponding IP address. This is a forward DNS lookup, used to verify that the DNS server correctly resolves the NVE's hostname.

In the Simulator, follow these steps:

1. In the left‑hand navigation clickDevices and Media→Cloud Tier Devices.

2. ClickAdd Cloud Tier Device(the “+” button).

3. In theAdd Cloud Tier Devicedialog, enter:

PowerProtect DD Host Name:ddve.dellemc.edu

DD Boost Username:ddboost_user

DD Boost Password:Student1!

Management Username:ddboost_user

Management Password:Student1!

Device Folder Name:DDCloudTier

Clone Pool:selectCloudtier_clone

Cloud Unit Name:NWRCloud

4. ClickSave.

In a NetWorker environment integrated with LDAP/AD, users must authenticate against the NetWorker Authentication Service to execute commands with appropriate privileges. Thensrlogincommand isused to authenticate the user with the Authentication Server, establishing the required session context. This resolves privilege-related failures when running NetWorker commands.

Dell Cloud Tier supports long-term retention by tiering deduplicated backup data from PowerProtect DD systems to various cloud object storage platforms. The supported platforms for this purpose include:

● Amazon Web Services (AWS)

● Dell Elastic Cloud Storage (ECS)

● Microsoft Azure​

These platforms are officially supported for seamless integration with Dell Cloud Tier, enabling efficient and secure long-term data retention.
