220-1202 Exam Dumps - CompTIA A+ Core 2 2025 Exam

Aclean installensures all malware is eliminated by completely wiping and reinstalling the OS. System restore or repair may leave traces.

FromQUENTIN DOCTER - COMPTIA A+ COMPLETE study GUIDE:

“If malware cannot be completely removed, perform a clean installation of the operating system. This ensures no remnants remain on the machine.”

Carbon fiber filamentcan producefine particles or fumesduring printing, which may be harmful when inhaled. Wearing anair filter maskis essential to protect the respiratory system.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“When working with advanced materials like carbon fiber, always use appropriate personal protective equipment such as air filter masks to prevent inhalation of dangerous particles.”

Comprehensive and Detailed Explanation From Exact Extract:

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.

If uploading fails only offsite,mobile data limits or restrictionsare the likely cause. Data caps or network management can interfere with uploads.

FromTravis Everett – All-in-One Exam Guide:

“When mobile users experience network issues, always check if the device has reached a data cap or roaming restriction.”

The correct answer is C. net use, which is the Windows command-line utility used to display, create, and remove mapped network drives and SMB (Server Message Block) connections. When working remotely through command-line interfaces, technicians often rely on net use to quickly verify which network shares are currently connected.

The Quentin Docter – CompTIA A+ Complete Study Guide explains that SMB is the protocol Windows uses for file and printer sharing, and mapped drives are maintained through SMB sessions. The net use command lists all active connections, including the drive letter, remote UNC path, and connection status.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide highlights that net use is especially valuable for remote troubleshooting because it does not require a graphical interface. This makes it ideal when administering multiple systems via command prompt or remote shell.

The Mike Meyers / Mark Soper Lab Manual clarifies that systeminfo displays OS and hardware details, hostname only shows the system name, and nslookup is used for DNS queries. None of those commands provide information about mapped SMB shares.

Since the task is to verify existing SMB mappings, net use is the only command that directly fulfills this requirement, making C the correct answer.

Comprehensive and Detailed Explanation From Exact Extract:

Since the issue has recurred after a temporary fix, it is likely a deeper or persistent configuration or server issue. Escalating the ticket to the next tier of support (e.g., network or system administrator) ensures further investigation and permanent resolution. Escalation is part of the standard support protocol when issues reoccur despite initial troubleshooting.

A. Rechecking remotely may confirm the issue, but doesn’t resolve it long term.

B. Providing documentation helps the user but doesn’t solve the root cause.

D. Keeping the ticket open is passive and doesn’t address the recurring issue.

Comprehensive and Detailed Explanation From Exact Extract:

Remote wipe is the best option to prevent unauthorized access to data when a mobile device is lost or stolen—especially if the user is unaware of the loss. It allows administrators or mobile device management (MDM) systems to remotely erase all data on the device, rendering it unusable for unauthorized users.

A. Encryption protects the data, but if the device remains powered and logged in, it may still be accessible.

C. Geofencing can restrict features based on location but does not erase data.

D. Facial recognition helps secure access but can be bypassed in some cases or fail in practical situations.

The correct answer is B. SSID configuration, because controlling SSID visibility and behavior directly affects which wireless networks devices can see and attempt to join. In shared office environments, multiple Wi-Fi networks may be present, increasing the risk of users accidentally connecting to the wrong network.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, SSIDs define how wireless networks are advertised and discovered. By modifying SSID settings—such as disabling broadcast or restricting auto-join behavior—technicians can prevent devices from attempting to connect to unauthorized or unintended networks.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that MDM solutions often preconfigure approved wireless profiles. Adjusting SSID configuration ensures devices only recognize and connect to sanctioned networks, reducing accidental associations and security risks.

The Mike Meyers / Mark Soper Lab Manual clarifies that IP filtering, content filtering, and port forwarding are network traffic control mechanisms. They do not prevent a device from seeing or attempting to connect to nearby Wi-Fi networks.

Because the goal is to prevent accidental Wi-Fi access, not filter traffic after connection, modifying SSID configuration is the correct and most effective solution.
