Free Practice Questions for CompTIA 220-1102 Exam

Running an antivirus scan for malicious software is the first step that a support technician should do when a user reports a virus on a PC. The antivirus scan can detect and remove the virus, as well as prevent further damage or infection. Quarantining the host, investigating how the malware was installed and reimaging the computer are possible steps that can be done after running the antivirus scan, depending on the situation and the results of the scan.

Shredding is a data destruction method that physically destroys the hard drive by cutting it into small pieces using a machine. Shredding ensures that data is completely removed from the hard drive and cannot be recovered by any means. Shredding is suitable for hard drives that contain PII (personally identifiable information), which is any information that can be used to identify, contact, or locate an individual. Degaussing, low-level formatting, and recycling are not data destruction methods that can guarantee complete data removal from a hard drive.

When a user needs to install optional features for a program that is already installed, the technician should:

Go to Programs and Features: Access this via the Control Panel.

Select the program: Find the installed program in the list.

Click on Change: The "Change" option allows modifications to the installed program, such as adding or removing features, without completely uninstalling and reinstalling the program.

This method is the most efficient and avoids unnecessary reinstallation of the software, which could lead to data loss or require reconfiguration.

The processor is the component that determines if the system supports virtualization technology (VTx), which is required for running virtualization software. The hard drive, memory and video card are not directly related to VTx support, although they may affect the performance of the virtual machines.

To prevent unauthorized access to data if a mobile device is lost or stolen, enabling biometric authentication (such as fingerprint or facial recognition) ensures only authorized users can unlock the device. Encryption protects stored data by making it unreadable without proper credentials, securing the device contents even if physically accessed. Remote wipe and device tracking assist in device recovery or data removal but do not directly prevent unauthorized access. Antivirus software and VPN access protect against malware and network threats but do not guard against physical access. Core 2 Security objectives emphasize biometric authentication and encryption as key security controls for mobile devices.

Certainly! Here are questions 26 to 31 reviewed and detailed per your format:

When disposing of e-waste, it is important to ensure that the data on the equipment is securely destroyed and that the disposal process complies with environmental regulations.

Non-disclosure agreement: Relates to confidentiality, not disposal.

Certification of destruction: The correct document verifying that the equipment has been disposed of in accordance with regulations and standards, ensuring data is irretrievably destroyed.

Low-level formatting: A method to wipe data but does not guarantee compliance with e-waste disposal regulations.

Shredding/drilling: Physical destruction methods that might be used, but certification of destruction is the documentation needed.

Comprehensive and Detailed In-Depth Explanation:

Device encryption ensures that even if someone gains physical access to the smartphone, they cannot access its contents without the encryption key.

A. Remote backups – Useful for data recovery but does not prevent unauthorized access.

B. Location tracking – Helps locate the device but does not protect its data.

C. PIN code screen lock – Adds security but is less effective than full encryption.

For ensuring data protection against local natural disasters and hardware failures, the best approach is to use an off-site solution that provides redundancy and is resilient to local disruptions.

Using an agent-based cloud backup solution: This method involves backing up data to a remote cloud server, providing protection against local disasters like floods, fires, or hardware failures since the data is stored off-site and can be accessed from anywhere.

Implementing a grandfather-father-son backup rotation: While effective for managing local backups, this method typically involves physical media which could still be vulnerable to local disasters.

Automating backups to a local network share: This keeps the backups within the same physical location, making them susceptible to local disasters.

Saving files manually to an external drive: This method is prone to human error and doesn't provide automated or off-site protection.

To ensure that Windows 10 laptops can automatically connect to Wi-Fi networks when employees take them home, the appropriate configuration is:

Network and Internet settings: These settings allow users to manage Wi-Fi connections, configure automatic connections to known networks, and manage network profiles.

Go to Settings > Network & Internet > Wi-Fi.

Ensure the option to connect automatically to the home Wi-Fi network is enabled.

Windows Firewall settings: These are used to manage firewall rules and do not control Wi-Fi connectivity.

Devices and Printers: Used for managing connected devices and printers, not for network connections.

Personalization settings: These settings are for customizing the appearance of the Windows interface and do not affect network connections.

Drilling is a method of physically damaging the hard drive by drilling holes through it, which renders the drive inoperable. However, it is not a secure method for ensuring data cannot be recovered. Methods such as wiping or degaussing are more secure.

To enable contactless payment, NFC (Near Field Communication) (Option C) needs to be enabled. NFC is the technology used in most mobile payment systems to enable close-range communication between the phone and a payment terminal.

Wi-Fi (Option A) and Bluetooth (Option D) are unrelated to contactless payments.

Nearby share (Option B) is a file-sharing feature, not a payment technology.

Slow loading of web pages on a mobile device while in an office environment is often related to network issues rather than device storage or data limits. The most accurate explanation is degraded network service, which means the quality or bandwidth of the network connection is poor, resulting in slow or unreliable internet access. This can be caused by network congestion, poor Wi-Fi signal strength, interference, or configuration issues with network infrastructure. Unlike exceeding data limits which typically results in throttling or no service, degraded service implies the network is active but performing poorly. Low storage space generally impacts device performance and app functionality but does not directly cause slow page loads. Sluggish response time is a vague term but could be related to degraded network service. Therefore, degraded network service is the best choice. This aligns with Core 2 objectives focusing on troubleshooting connectivity issues and network performance degradation.

Avoiding personal interruptions (such as browsing social media) shows respect and attentiveness, which is critical in building trust during customer interactions. Actively listening and taking notes demonstrates that the technician values the customer's concerns and is committed to resolving issues. Following up (A) and clarifying statements (D) are good but not immediate communication techniques during the interaction. Providing documentation (C) and maintaining attire (F) are operational but less relevant to active listening. Core 2 operational procedures highlight active listening and avoidance of distractions as key customer service skills to improve technician-customer communication.
