Which of the following statements is true of distributed file system (dfs) namespaces?

Amazon FSx for Windows File Server supports the use of Microsoft's Distributed File System (DFS) Namespaces. You can use DFS Namespaces to group file shares on multiple file systems into one common folder structure (a namespace) that you use to access the entire file dataset. DFS Namespaces can help you to organize and unify access to your file shares across multiple file systems. DFS Namespaces can also help to scale file data storage beyond what each file system supports (64 TB) for large file datasets—up to hundreds of petabytes. Show
Setting up DFS Namespaces for grouping multiple file systemsYou can use DFS Namespaces to group multiple file systems under a single namespace. In the example that follows, the domain-based namespace (example.com\corp) is created on two namespace servers, consolidating file shares stored on multiple Amazon FSx file systems (finance, marketing, sales, home_directories). This allows your users to access file shares using a common namespace. Given this, they don't need to specify file-system DNS names for each of the file systems hosting the file shares. Amazon FSx cannot be added to the root of the DFS share path. These steps guide you through creating a single namespace (example.com\corp) on two namespace servers. You also set up four file shares under the namespace, each transparently redirecting users to shares hosted on separate Amazon FSx file systems.

Distributed file systems enable users to access file data that is spread across multiple storage servers. A DFS should uphold data integrity and be secure and scalable.Distributed file systems can share data from a single computing system among various servers, so client systems can use multiple storage resources as if they were local storage. Distributed file systems enable organizations to access data in an easily scalable, secure and convenient way. A DFS enables direct host access to file data from multiple locations. For example, NFS is a type of distributed file system protocol where storage resources connect to a computer by network resources, such as a LAN or SAN. Hosts can access data using protocols such as NFS or SMB. Admins can add nodes to a DFS to scale quickly. A DFS should create backup copies to prevent data loss if there are drive failures. Features of distributed file systemsThere are various features to a DFS, such as the following:
Standalone DFS versus domain-based DFS namespacesStandalone distributed file systems do not use Active Directory (AD). Instead, they are created locally with their own unique root directories. They cannot be linked with any other DFS entities. They are not as popular as domain-based distributed file systems. Domain-based DFS namespaces store the configuration of a DFS in AD. This makes DFS easier to use and more accessible throughout a system. Strengths and limitations of distributed file systemsDFS technology provides file survivability by distributing critical files and databases across multiple storage devices. Some of these storage entities are at alternate company locations and can also be cloud-based, providing additional DR support. Users can enhance data movement across storage nodes. There may be difficulties if there is a change in file servers, file storage applications and other storage protocols that may not be compatible with the DFS/NFS application. There are risks of data loss if security provisions are not in place. Also, movement of data from one storage node to another may result in lost data. Dig Deeper on Primary storage devices
Which of the following is a distributed file system DFS function?The Distributed File System (DFS) functions provide the ability to logically group shares on multiple servers and to transparently link shares into a single hierarchical namespace. DFS organizes shared resources on a network in a treelike structure.
What is a DFS namespace?DFS (Distributed File System) Namespaces is a role service in Windows Server that enables you to group shared folders located on different servers into one or more logically structured namespaces.
What is the difference between DFS namespace and DFS replication?DFS Namespace (DFS-N) – DFS namespace allows the building of the namespace and the logical folder structure. These folders can be on multiple servers, as you'll see later. DFS Replication (DFS-R) – DFS Replication replicates folders to other members in the network.
What are the two types of DFS namespace?When creating a namespace, you must choose one of two namespace types: a stand-alone namespace or a domain-based namespace.
