Comprehensive and Detailed Explanation From Exact Extract:
BitLocker is Microsoft's full disk encryption technology built into Windows Pro and Enterprise editions. It encrypts the entire drive, protecting data if the device is lost or stolen. BitLocker can use TPM (Trusted Platform Module) and can be configured with PINs or USB keys for added security.
A: Active Directory is for centralized user and policy management in domains.
B: NTFS is the file system format and doesn't provide encryption by itself.
C: EFS (Encrypting File System) encrypts individual files or folders, not the entire drive.

See explanation below.
Explanation:
The completed configuration:
1. Wireless AP (LAN side)
1. LAN IP: 192.168.10.1
2. Encryption: WPA2 PSK
2. Router (port-forward rule)
1. Allow TCP Any 3389
This forwards inbound RDP traffic (TCP/3389) from the Internet to the Windows PC, enabling Remote Desktop access.
3. Firewall (screened subnet side)
1. LAN IP: 10.100.0.1
4. Device placement
1. PC: place behind the router (where the port-forward rule points).
2. Game console: place on the Wireless AP (so it can use chat and extra services over WPA2 PSK).
3. Firewall: place in front of the screened subnet (with its 10.100.0.1 IP facing that subnet).
* The Windows PC is placed in the screened subnet (behind the firewall) for enhanced security. Remote access to this PC requires port forwarding of TCP port 3389 (RDP), which is correctly configured through the router.
* The Game Console is placed on the Wireless AP LAN, using WPA2 PSK for a secure wireless connection. Game consoles typically use peer-to-peer chat and online services that require open access without firewall restrictions, which is why the console is not placed behind the firewall.
CompTIA A+ 220-1102 Reference Points:
* Objective 3.4: Given a scenario, implement best practices associated with data and device security.
* Objective 2.4: Given a scenario, use appropriate tools to support and configure network settings.
* Study Guide Reference: CompTIA A+ Core 2 guides recommend using screened subnets (a type of DMZ) for systems needing controlled external access, such as remote desktops, while placing gaming and media devices on less restricted networks for full functionality.

Badge readers are electronic access control systems that require authorized users to scan a badge (e.g., RFID or magnetic strip cards) to gain access to restricted physical locations. These systems typically log all access attempts-successful or denied-providing both detection and recording of access events.
A). Bollards are physical barriers to prevent vehicle access.
B). Video surveillance can record access visually but does not track identity unless integrated with access control systems.
D). A fence restricts access but doesn't detect or record who entered.

Running atnear full storage capacitysignificantly slows down smartphones. iOS in particular requires space for caching and temporary files. Performance improves when storage is cleared.
FromMike Meyers' Lab Manual:
"Lack of free space causes mobile operating systems to struggle with temp files and updates. Performance improves significantly with adequate storage."

Once the system is cleaned, the next priority is toeducate the useron safe practices to prevent recurrence.
FromQuentin Docter - CompTIA A+ Complete Study Guide:
"Post-malware remediation should include user education to prevent reinfection and identify how the malware was introduced."
