OBJ-4.4: Before working on a computer or server, you should always remove your jewelry. Jewelry such as bracelets and necklaces can often dangle and come into contact with sensitive components or electrical connections that can cause damage to the components or injure you. Therefore, all jewelry should be removed before working on an electrical system or computer to reduce the risk of shock. A grounding probe is not required to discharge the power supply since the technician should never be opening up the case of a power supply. The old power supply should be safely disposed of after it is removed, but it should not be removed until you have removed your jewelry. Proper cable management is important when installing a power supply, but again this should only occur after removing your jewelry.

OBJ-1.9: An unattended installation is a traditional method of deploying a Windows operating system in a large enterprise environment. Unattended installations use an answer file that contains user input to various GUI dialog boxes that would otherwise appear during the installation process. Unattended installation is the most practical way to install Windows when the client computers have different hardware components, and an image file cannot be used. Unattended installations save deployment time and can be used either for clean installs or in-place upgrades. A clean install is a means of installing the operating system to a new computer or completely replacing the operating system on an old computer. All existing user data or settings will be deleted during the setup process when a clean installation is conducted. An in-place upgrade is a means of installing an operating system on top of an existing version of the operating system. Applications, user settings, and data files are retained when conducting an in-place upgrade. A repair is used to check and replace any modified system files within the operating system.

OBJ-2.7: The FaceID and TouchID screen locks rely upon biometric data to securely unlock the device. Face ID is a facial recognition system designed and developed by Apple. Touch ID is an electronic fingerprint recognition feature designed and released by Apple. Since biometrics are body measurements and calculations related to human characteristics, the use of a person's face or fingerprint is classified as a biometric authentication system. A swipe lock is a term for unlocking a device by tracing a predetermined on-screen pattern or joining dots on the screen. This was commonly used in Android devices until biometric methods like fingerprint scanners and facial recognition became more prevalent. A passcode unlock is a term for unlocking a device by entering a 4 to 6 digit pin.

OBJ-1.2: The robocopy tool is used to mirror or synchronize directories and their contents. Robocopy will check the destination directory and remove files no longer in the main tree. It also checks the files in the destination directory against the files to be copied and doesn't waste time copying unchanged files. The xcopy tool, on the other hand, copies all of the files from one directory to another. To meet your boss's requirements to synchronize the two hard drive's contents, you must use robocopy since it will also remove files from the second drive that were removed from the first drive, too. The copy command is used to copy one or more files from one location to another. The copy command cannot copy files that are 0 bytes long or for copying all of a directory's files and subdirectories. The cp command is used in Linux to copy one or more files and directories from one location to another.

OBJ-2.2: Simultaneous Authentication of Equals (SAE) is a password-based authentication and password-authenticated key agreement method used in WPA3 that replaced the 4-way handshake used in WPA-based wireless networks. The SAE handshake is also known as the dragonfly handshake. Enhanced Open enables encryption for traffic being sent and received over a wireless network when still using open authentication. AES Galois Counter Mode Protocol (GCMP) is a high-performance mode of operation for symmetric encryption that supports authenticated encryption with associated data (AEAD). Management protection frames protect unicast and multicast management action frames to protect against eavesdropping and forgery in WPA3-based wireless networks.

exFAT

OBJ-1.4: Sleep or standby mode is used to save the current session to memory and put the computer into a minimal power state to save battery life when the system is not being used. The computer takes less time to start up again from the sleep or standby mode than it does from the hibernate mode. Hibernate mode is used to save the current session to disk before powering off the computer to save battery life when the system is not being used. The computer takes longer to start up again from hibernate mode than it does from the sleep or standby mode. Shutdown mode completely powers off the computer and does not save the current user session to disk. Instead, the shutdown will close all open files and log out the user during the shutdown process. A lock will secure the desktop with a password while leaving programs running.

firmware updates

Which command-line tool and option on a Windows system is used to force a background refresh of all group policy settings on a system? dism /force gpresult /force sfc /force (Incorrect) gpupdate /force (Correct)

gpupdate /force

OBJ-1.8: The only file system format that would work for this situation is exFAT. A macOS system can format a hard drive as APFS, HFS+, HFS, exFAT, or FAT32. The Windows system would only be able to read exFAT or FAT32. Unfortunately, FAT32 only supports drive sizes up to 32 GB, and file sizes up to 4 GB. Therefore, exFAT should be used as it supports sizes up to 128 petabytes.

loop

OBJ-3.2: If an automated system update fails to install, you should research the error number for the failed update to determine if the issue is a known error. Based on the error code, you can then determine the best method to overcome the issue. For example, a common cause of errors is inadequate space on the hard disk. If a technician needs to determine how to solve this issue best, researching the error code at Microsoft.com can help.

OBJ-4.8: A loop deviates from the initial program path to some sort of logic condition. In a loop, the computer repeats the task until a condition is met. Often implemented with For, For Next, While, or Do While statements. For example, a short script like (For i=1 to 100, print I, next) would print the numbers from 1 to 100 to the screen. A branch is used to control the flow within a computer program or script, usually based on some logic condition. Often, these are implemented with IF THEN ELSE statements. A variable is a placeholder in a script containing a number, character, or string of characters. Variables in scripts do not have to be declared (unlike in programming languages) but can be assigned a value. Then, the variable name is referenced throughout the script instead of the value itself. A constant is a specific identifier that contains a value that cannot be changed within the program. For example, the value to convert a number from F to C is always 5/9 because the formula is C = (F -32) * 5/9.

OBJ-4.8: Windows PowerShell enables you to perform management and administrative tasks in Windows 7 and later. It is fully integrated with the operating system and supports both remote execution and scripting. Microsoft provides the Windows PowerShell Integrated Scripting Environment (ISE) to help create and manage your Windows PowerShell scripts. If you want to save a series of PowerShell commands in a file to rerun them later, you effectively create a PowerShell script by creating a text file with a .ps1 extension. The file can contain a series of PowerShell commands, with each command appearing on a separate line. Python is a general-purpose programming language that can develop many different kinds of applications. It is designed to be easy to read, and the programs use fewer lines of code compared to other programming languages. The code runs in an interpreter. Python is preinstalled on many Linux distributions and can be installed on Windows. Python scripts are saved using the .py extension. Batch scripts run on the Windows operating system and, in their simplest form, contain a list of several commands that are executed in a sequence. A .bat file is used for a batch script. You can run the file by calling its name from the command line or double-clicking the file in File Explorer. Generally, batch file scripts run from end to end and are limited in branching and user input. A shell script is a file that contains a list of commands to be read and executed by the shell in Linux and macOS. A .sh file is used for a shell script and its first line always begins with #!/bin/bash that designates the interpreter. This line instructs the operating system to execute the script. Shell scripts allow you to perform various functions. These functions include automation of commands and tasks of system administration and troubleshooting, creating simple applications, and manipulating text or files.

When you turn on the system, you notice that Windows only recognizes 3.5 GB of RAM. Which component should be upgraded to correct this issue?

replace the OS with Windows 10 Pro (x64) edition

OBJ-1.8: The Windows Update program can download critical fixes, security patches, and driver updates. The Windows Update program cannot download and install firmware updates because the firmware must be updated before the Windows operating system begins running during the boot process.

research the error number for the failed update and determine if there is a known issue with this update

OBJ-1.4: The Devices and Printers section of the Control Panel allows a technician to manage the printers, scanners, and other external devices connected to a Windows computer. The System section of the Control Panel allows a technician to see information about the workstation, including the processor type, amount of memory, and operating system version installed on the computer. The Device Manager is used to view and control the hardware attached to the computer. The device manager will highlight a piece of hardware that is not working so that a technician can repair or replace it. The Programs and Features section of the Control Panel allows a technician to install or remove applications, software packages, and features in the Windows operating system.

OBJ-1.9: Primary partitions are limited to only four primary partitions on a system using MBR. To overcome this limitation, extended partitions can be used. An extended partition is a partition that can be divided into additional logical drives. Unlike a primary partition, you don't need to assign it a drive letter and install a file system. When using MBR, you can support up to 23 logical drives in an extended partition. The swap partition on a Linux system is a portion of the hard disk formatted with a minimal kind of file system and used in situations when the operating system runs out of physical memory and needs more of it. It can only be used by the memory manager and not for the storage of ordinary data files.
