Questions and Answers

In multifaceted enterprise environments utilizing Windows 10 Enterprise, how does AppLocker enhance security compared to traditional Group Policy-based software restriction policies, especially considering zero-day exploits?

  • AppLocker primarily restricts software based on publisher, path, and file hash, offering less granular control than traditional policies, but superior ease of management during rapid deployment scenarios.
  • AppLocker uses machine learning to predict and prevent unknown software behavior, significantly reducing false positives and negatives compared to traditional Group Policy, which relies on predefined rules.
  • AppLocker integrates seamlessly with third-party antivirus solutions, providing real-time scanning capabilities, whereas Group Policy lacks such integration, depending solely on signature-based detection.
  • AppLocker's ability to control application execution based on attributes like digital signatures and file origins provides a more robust defense against zero-day exploits compared to Group Policy's reliance on known signatures. (correct)

Windows Upgrades

  • An upgrade keeps files and applications intact while updating the OS, but an install overrides everything for a fresh start.
  • An in-place upgrade maintains customizations, files, and applications; launch upgrade from within existing OS.
  • A clean install wipes the drive and reloads the OS, requiring a backup and bootable media from a media creation tool.
  • Upgrading between 32-bit and 64-bit versions is not possible without a clean install.
  • Can upgrade to the same or higher-level edition.
  • In-place upgrades to Windows 10 are possible from Windows 7 and 8.1, but not from 8.0 (upgrade to 8.1 first).
  • Windows 11 in-place upgrades are only available directly from Windows 10.
  • After upgrading, confirm applications and user data are working.
  • If there are issues after upgrading, you can revert via settings.
  • Also install service packs, security patches, driver updates, and application updates.
  • Check Windows Update for the latest patches.

Windows Upgrades - Exam Q&A

  • An upgrade updates the OS, keeping files/applications intact. A clean install overrides everything, requiring backup and restore.
  • In-place upgrades are launched from within the existing OS, maintaining consistency without needing to reinstall applications or restore files.
  • A clean install is needed to upgrade between 32-bit and 64-bit Windows. Back up files, use bootable media created from Microsoft files.
  • Upgrading between 32/64-bit versions isn't possible. Can upgrade to the same/higher edition (e.g., Windows 10 Home to 11 Home/Pro).
  • In-place upgrade to Windows 10 valid from 7/8.1, but not from 8.0 (must upgrade to 8.1 first). Windows 11 in-place upgrade only from Windows 10.
  • After upgrading, confirm applications/data, install service packs/patches, and check Windows Update.
  • Check Microsoft's documentation to confirm available upgrade paths

Windows Command Line

  • Windows command prompt provides OS access via a Command Line Interface (CLI).
  • Most commands run with standard user privileges, some need elevated/administrative prompt.
  • Access command prompt by searching "cmd" or "command prompt."
  • Use help command or /? for details on other commands like dir, chkdsk, and copy.
  • dir: Lists files and directories in the current folder.
  • cd (chdir): Changes the current directory. Use \ to delineate folders. Use .. to move to the parent directory.
  • mkdir (md): Creates a new directory.
  • rmdir (rd): Removes a directory.
  • Drive letters represent drives/partitions; C: is commonly used for the local storage drive.
  • hostname: Displays the name of the computer.
  • format: Writes a new file system to a partition, erasing data.
  • copy: Copies files from source to destination; /v verifies, /y skips overwrite prompts.
  • xcopy: Copies files, directories, and subdirectories using the /s option.
  • robocopy: Robust copy, setting bandwidth limits, resuming interrupted copies.
  • shutdown: Shuts down/restarts the system
  • /s: Shutdown
  • /r: Restarts
  • /t: Specifies time in seconds to wait before shutdown.
  • /a: Aborts shutdown process.
  • diskpart: Creates, modifies, and deletes disk partitions.
  • winver: Displays the Windows version.
  • gpupdate: Updates group policies. Use /force to apply all policies.
  • gpresult: Shows current Group Policy configurations.

Command Line Tools - Exam Style

  • robocopy is the most efficient choice, it allows you to copy subdirectories, and control bandwidth usage, and resume interrupted copies.
  • hostname command displays the computer's name.
  • cd command navigates directories or move back to the previous directory, using the.. shortcut.
  • gpupdate /force ensures all users receive the latest group policy updates immediately.
  • format [drive letter] creates a new file system on a specific partition.
  • gpresult /r verifies group policy settings, and gpupdate /force applies new policies.

Windows Network Command Line

  • Ipconfig: Provides IP address, subnet mask, DNS settings, and IP configurations.
  • Ipconfig /all: provides extensive details including hostname, proxy information, DHCP server, and DNS server.
  • Ping: Checks device communication and round-trip time.
  • Default is four requests
  • Displays statistics such as packet loss and round-trip time averages.
  • Netstat: Displays network statistics for Windows, Linux, and Mac OS.
  • netstat -a: Lists all devices connected to, or connecting to the computer.
  • netstat -b: Shows binaries used, requires admin privileges.
  • netstat -n: Displays IP addresses without resolving names.
  • Output includes protocols, local/foreign addresses, connection state.
  • Nslookup: Queries DNS server to resolve domain name to IP address.
  • Net: Windows commands for connecting, viewing, and sharing information.
  • net view: Shows available shares on a remote server.
  • net use: Maps a drive letter to a network share.
  • net user: Views/Modifies user accounts.
  • Traceroute (tracert): Identifies packet route to destination using ICMP and TTL.
  • Routers decrease TTL, TTL=0 sends ICMP Time Exceeded message.
  • Pathping: Combines ping and traceroute, measures round-trip times and packet loss at each hop.
  • Use the -n option to display IP addresses instead of names.

Windows Network Commands - Troubleshooting

  • Use ipconfig to check IP, subnet mask, gateway, DNS; ping gateway for local connectivity; nslookup to resolve domain to IP if can't access the website.
  • netstat -b (with admin privileges) shows which applications use the most network bandwidth.
  • Traceroute works by increasing TTL values, routers send back ICMP Time Exceeded when TTL reaches zero.
  • Asterisk (*) or "Request timed out" indicates a non-responding router due to a firewall.
  • Pathping identifies routing issues by showing packet loss at each hop, unlike traceroute.
  • net use [drive letter]: \\[server name]\[share name] maps a network drive.
  • Minimum RTT represents the fastest possible communication, while the maximum RTT indicates the slowest.

Task Manager

  • The Task Manager provides real-time performance monitoring.
  • Access via Control-Alt-Delete, right-click the taskbar, or Control-Shift-Escape.
  • The Services tab manages background applications.
  • The Startup tab manages applications that launch when you log into Windows
  • In Startup tab, you can disable applications to troubleshoot startup issues.
  • The Processes tab displays applications and background processes with associated metrics.

  • The Performance tab shows CPU, memory, storage, and network information over time.
  • The networking piece is included in the Performance tab.
  • The Users tab displays each user and the applications they are running.

Task Manager - Troubleshooting Scenarios

  • Open Task Manager (Ctrl+Alt+Del, right-click taskbar, Ctrl+Shift+Esc) and use Processes tab, sort by CPU/Memory to identify resource-intensive processes.
  • Use Startup tab to disable recently installed application and assess impact and restart the computer.
  • Restart a malfunctioning background process in the Services tab.
  • Use the Performance tab to view CPU, memory, storage, and network resources over time.
  • In the Performance tab, network utilization, link speeds, and other metrics.
  • The Users tab lists users and their applications; disconnect users or modify account settings.
