CompTIA 220-1202 Exam Dumps

The requirement is secure remote access to both Linux and Windows servers while working from home. A VPN is designed to securely extend internal network access across the public Internet. Quentin Docter states that a ''virtual private network (VPN) extends your company's internal network across the Internet,'' allowing clients to connect ''securely and privately,'' and that it creates a secure tunnel ''through the process of encryption and encapsulation,'' making the remote host appear as part of the internal network with an internal IP.

Mike Meyers' Lab Manual reinforces that VPNs work by ''setting up an encrypted tunnel between the two points---over the open Internet---creating what we call a virtual private network (VPN),'' enabling remote users to function as if they were plugged into the office LAN.

FTP is not secure by default and is file-transfer-only (not full network access). RDP is Windows-focused and provides a remote desktop session, not generalized secure access to mixed OS servers. RMM is a management platform for IT monitoring/maintenance, not the primary secure access method for end users. Therefore, VPN (B) best meets the requirement.

To ensure the authenticity of a downloaded application, the most reliable method is to verify the file's hash (e.g., SHA256, MD5) against the value provided by the legitimate vendor. If the hash values match, the file has not been altered or tampered with. This verification confirms the integrity and authenticity of the executable.

B . Process IDs are dynamic and not unique to specific software.

C . Running in safe mode doesn't validate legitimacy---it only runs the app in a minimal environment.

D . File names can be spoofed; matching the name does not prove authenticity.

CompTIA A+ 220-1102 Objective 2.2: Compare and contrast authentication and software integrity verification methods.

If the phone works on Wi-Fi but not off Wi-Fi, the most likely issue is that cellular data is disabled (or restricted). This aligns directly with the CompTIA A+ objective language for mobile troubleshooting, which explicitly includes ''wireless/cellular data network (enable/disable).'' After travel, users often enable airplane mode or disable cellular data to avoid roaming charges, and sometimes forget to re-enable it.

Quentin Docter's mobile connectivity discussion repeatedly distinguishes Wi-Fi access from cellular connectivity and treats cellular settings as a primary area to verify when Internet access is not available away from Wi-Fi. While data caps/limits could throttle service, they usually don't make all non-Wi-Fi browsing and email impossible immediately. VPN issues might block some access, but the simplest ''most likely'' resolution based on the symptom is re-enabling cellular data. Reinstalling the SIM is possible, but again not the first, most likely fix given the scenario framing. Therefore, Enable cellular data (A) is correct.

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.

CompTIA A+ 220-1102 Objective 2.4: Compare and contrast physical security measures.

A VPN creates a secure tunnel from the user's home network into the corporate network, providing the necessary routing and access controls for the laptop to reach internal file servers. Without a VPN, the device remains outside the corporate LAN and cannot directly reach protected resources.
