Q

what’s the difference between Windows Pro and Windows Pro for Workstations?

A

Windows Pro for Workstations can support up to four-way multiprocessing, can support 6 TB of memory

22
Q

Windows Enterprise

A

can do everything Windows Pro can do plus application and user environment virtualization, direct access, credential guard, Windows To Go
only volume licensing

23
Q

App-V

A

application virtualization tool that protects the rest of the OS from any kind of malware

24
Q

user environment virtualization (UE-V)

A

used to capture, save, and manage Windows 10 OS and application settings on an individual user environment level; allows multiple people to use the same machine but separate all their settings

25
Q

Direct Access

A

used to allow connectivity for remote users without the use of a VPN

26
Q

Credential guard

A

allows for virtualization-based security and only grants access to privileged systems

27
Q

Windows To Go

A

creates an image version of a corporate Windows 10 environment that can be run on a user’s personal computer

28
Q

BitLocker

A

enables the user to encrypt all the information on a disk drive

29
Q

Group Policy Editor (gpedit.msc)

A

is used to create and apply OS and software application settings. These could be configured on each machine individually, but more typically they are applied via policies configured on the DC so that client machines have uniform desktop styles and settings.

30
Q

Remote Desktop Protocol (RDP)

A

allows a user to connect to the machine and operate it over a network.

31
Q

in-place upgrade

A

the setup program for the new version is launched from within the current OS. The applications, configuration settings, and data files should all be preserved as long as they are compatible with the new version.

32
Q

NTFS

A

a file system used by Windows operating systems to organize and manage data on storage devices such as hard drives and SSDs. It offers features like support for large file sizes, file and folder permissions, encryption, and compression. NTFS is known for its reliability, security, and advanced features, making it suitable for both personal and enterprise-level storage needs.

33
Q

exFAT (Extended File Allocation Table)

A

a file system developed by Microsoft for removable storage media. It supports large file sizes and capacities, overcoming limitations of FAT32. Known for cross-platform compatibility, it is widely used in devices like flash drives and external storage for its flexibility and interoperability.

34
Q

FAT32

A

a variant of FAT that uses a 32-bit allocation table, nominally supporting volumes up to 2 TB. The maximum file size is 4 GB minus 1 byte.

35
Q

journaling

A

makes recovery after power outages and crashes faster and more reliable.

36
Q

snapshots

A

This allows the Volume Shadow Copy Service to make read-only copies of files at given points in time even if the file is locked by another process. This file version history allows users to revert changes more easily and also supports backup operations.

37
Q

POSIX Compliance

A

To support UNIX/Linux compatibility, Microsoft engineered NTFS to support case-sensitive naming, hard links, and other key features required by UNIX/Linux applications.

38
Q

dynamic disks

A

disk management feature allows space on multiple physical disks to be combined into volumes.

39
Q

ext3

A

a standard Linux file system that added support for journaling.

40
Q

ext4

A

delivers better performance than ext3 delivers and would usually represent the best choice for new systems.

41
Q

what filesystems can linux support?

A

ext3, ext4, FAT/FAT32, NFS

42
Q

Apple File System (APFS)

A

supports journaling, snapshots, permissions/ownership, and encryption

43
Q

external hardware token

A

a smart card or USB form factor device that stores some cryptographic user identification data. The user must present the token and supply a password, PIN, or fingerprint scan to authenticate.

44
Q

what are potential impacts to business when deploying new applications?

A

commercial software must be used within constraints of its license, support for software might be paid-for or by internal team, and complex apps can have substantial and expensive user-training requirement

45
Q

what operational impacts should you consider when installing new applications?

A

use of automation, GPOs, network-based installers, centralized management tools

46
Q

what potential impacts to the network should be considered when deploying applications?

A

the bandwidth the app needs to operate and use

47
Q

Workgroups

A

decentralized collection of managed computers and users. Each computer will have local account created that can be used for local authentication on the computer.

48
Q

AppLocker

A

allows for policies to be created in Group Policy to control the access to applications. can be based on the program’s path, publisher, or hash. only on Win10/11 enterprise ed.

49
Q
