Question 14

What are some advantages of ReFS?

Answer 14

• ReFS gives Accelerated VHDX options in Hyper-V; these options permit massive performance increases when creating and extending a virtual hard disk, when merging checkpoints, and when performing backups.
• A block cloning approach is key to excellent checkpoint performance.
• Use of a 64 KB block size allows optimal performance in Hyper-V, with partition alignment handled automatically by Hyper-V.
• When your Storage Spaces pool uses ReFS as the underlying on-disk format, it leverages new features to greatly improve the repair process.
• ReFS v2 uses the concept of cluster “bands” to group multiple chunks of data together for efficient I/O; this really helps with your use of data tiering—specifically in moving data between tiers.
• Automatic integrity checking exists in ReFS.
• ReFS features new data scrubbing techniques.
• ReFS offers better protection against data degradation. - It features built-in drive recovery and redundancy. ReFS supports up to 1 trillion terabytes.
• You can create new volumes faster with ReFS.

Question 15

Question 20

What are some additional considerations concerning permissions?

Answer 20

• File permissions always take precedence over folder permissions—that is, if a user can execute a program in a folder, this is possible even if such permissions do not exist at the folder level.
• Permissions are cumulative—that is, users obtain the cumulative effect of different permissions they might obtain through different group memberships.
• Deny permissions always override Allow permissions. Note that this is the one powerful exception to the preceding rule of permissions being cumulative.
• Permissions migrate from the top down in a process known as inheritance. Inheritance allows files and folders created within already existing folders to have a set of permissions automatically assigned to them.
• You enable or disable inheritance in the Advanced Security Settings window
