Configuring And Installing The OS (Chapter 2) Flashcards
OS Installation Overview
1) Select installation method
2) Check Compatibility
3) backup existing files & settings (upgrading)
4) Choose Boot method to load OS setup file
5) Prepare fixed disk and copy setup files
6) Configure installation
7) Verify installation
Attended Installation
An OS installation where the installation requires users to configure options
Unattended Installation
An installation that grabs all installation configuration from an input file
Clean install
Installing the OS, by replacing the previous OS.
- Deletes all apps, settings and data files.
- General more reliable than upgrading
In-place Upgrade
Installing the OS on top of an existing version of the OS.
- Retains apps, settings & data files
- can be used to upgrade to a newer OS version or repairing installation files
Compatibility
Windows Logo’d Product List (LPL) and Hardware Compatibility List (HCL) is a list of hardware that is compatible with the OS compatible.
- checks OS compatibility
- Upgrade path
- Hardware & application compatibility
Installation Boot Method
How an OS installation program and settings are loaded onto a PC
- Optical disc
- External flash drive (media creation tool)
- Network boot (PXE)
Secure Boot
A process during POST which checks that all components of the system has a digital signes driver certificate
- Available in UEFI
- Restricts OS installation to trusted software
Installation Methods
- Windows EXE and MSI installer
- macOS DMG and PGK installer
- Linux APT (DEB) and YUM (RPM) package manager and formats
- ISO mountable
- physical media
System Partition
The bootable partition on drive that is formatted with FAT32
Boot Partition
The partition that contains the OS
Multiboot
A system with multiple OS installed on separate partitions.
- asks which OS to open when the system boots up
Account consideration
Workgroup
- a small group of computers on a network that share resources in a peer-to-peer fashioned
Domain
- a group of computers that share a common account database (directory)
Microsoft Account
- account that allows user to sync data across devices, download Microsoft apps
Local Account
- an account that is associated with computer
Post-Installation Task
- All hardware have required drivers
- Check log files & device manager to ensure all hardware has been detected
- activation key
Post-Installation Task
- All hardware have required drivers
- Check log files & device manager to ensure all hardware has been detected
- activation key
Unattended Installation files
Answer Files
- files that contain all the answers that windows installation requires for configuring (product key, settings, disk partition,ect)
Image deployment
- a file that contains a clone of an already set up windows OS, contains apps, file data, accounts, settings
Drive Cloning and Sysprep
- Dism tool reads the content of a drive and creates a Disk Image as a .WIM file format
- Sysprep is used to ensure that the disk image is unique
Fragmentation
Occurs when data file are not stored to contiguous sectors on a disk, decreasing performance by making the read/write head move between fragments
Defragmentation tool
- reorders data files into contiguous sectors
Linux Disk Management Tools
- df
- du
- Fsck
Patch Management
Identifies, test and deploys OS and applications updats
Scheduled backups
personal
- external harddrive/media
- cloud
Networks
- cost effective tap
- third party utilities
Windows backup toold
- File History
- Windows Backup & Restore Centre
Backup Frequency
Reflects how much lost work can be tolerated
Backup Retention
The period of time that any given backup job is kept
Backup Chains
Full
- backups all selected data regardless of when it was previously backed up
- high time & storage required
- single job recovery
- clear archive attribute
Incremental
- backups new and modified files since last backup
- low time & storage required
- multiple job recovery
- clears archive attribute
Differential
- New and modified files since last full backup
- moderate time & storage required
- two jobs recovery
- doesn’t clear archive attribute
Synthetic Backups
Assembles a full back from other back up jobs (incremental/differential)
1) Starts with a full backup
2) makes chain backups jobs of either incremental or differential
3) next full back up is scheduled
4) last incremental/differential job is preformed
5) synthesis a full back up from all back up jobs
GFS backups
“Grandfather-Father-Son” label media rotation scheme
Son
- most recent
- shortest retention period (1 week)
Grandfather
- oldest
- longest retention period (1 year)
3-2-1 backup rules
- 3 copies of all data
- across 2 media types
- 1 copy held offline & off-site
