A comprehensive set of flashcards covering RAID-5 and various storage management concepts outlined in Course 740 Lesson 4.

What is RAID-5?

It is a fault-tolerant volume where data is interleaved across three or more disks with parity information.

What does Storage Spaces in Windows Server 2016 allow you to do?

It allows you to combine multiple disks into a single logical volume that can be mirrored for protection against drive failures.

What is the main function of a two-way mirror in Storage Spaces?

It writes two copies of your data to protect against a single drive failure.

What is Network Attached Storage (NAS)?

What does LUN stand for and what does it represent?

Logical Unit Number; it refers to a portion of a storage subsystem.

What is Data Deduplication?

A feature that reduces disk space by removing duplicate data and preserving storage capacity.

What are the capabilities of Data Deduplication in terms of optimization ratios?

It can optimize ratios of 2:1 for general file servers and up to 20:1 for virtualization data.

What tool can you use to monitor deduplication in Windows?

You can use the Deduplication Evaluation Tool (DDPEVAL.exe) to estimate capacity savings.

What is the purpose of Dynamic Memory in Windows Server 2016?

It allows automatic reallocation of memory to the VM from a shared memory pool based on demands.

What is the significance of Secure Boot in Generation 2 VMs?

It ensures that each component loaded during the boot process is digitally signed and validated.

What is BitLocker Drive Encryption?

It encrypts your hard drive to protect against unauthorized access and brute force attacks.

What does the Grant-VMConnectAccess cmdlet do?

It grants access to a user to a virtual machine or machines in Hyper-V.

What is the role of the Hyper-V Manager?

It is the administrative tool used to manage virtual machines and their settings in Hyper-V.

What is a differencing disk used for in Hyper-V?

It allows you to create a virtual disk that preserves an existing image while allowing modifications without changing the parent image.

What needs to be done to use a pass-through disk in Hyper-V?

The VM must have exclusive access to the physical disk, and the disk must be offline in Windows.

What does 'Merge-VHD' command do?

It merges a differencing disk into its parent disk.

What is the purpose of Volume Shadow Copy Service (VSS)?

It enhances backup capability by allowing backups of files that are open or locked.
