Free Practice Questions for CompTIA 220-1102 Exam

Journaling is a feature that helps maintain the integrity of the filesystem by keeping a record of changes not yet committed to the main file system. This feature is supported by various filesystems, but not all.

Option A: NTFSNTFS (New Technology File System) is a filesystem used by Windows that supports journaling. This makes it resilient to corruption from unexpected shutdowns or crashes by keeping a log of file changes.

Option B: exFATexFAT (Extended File Allocation Table) does not support journaling. It is optimized for flash drives and large files but lacks advanced features like journaling.

Option C: HFSHFS (Hierarchical File System) is an older filesystem used by Apple. HFS+ (also known as Mac OS Extended) supports journaling, but HFS itself does not.

Option D: ext2ext2 (Second Extended File System) is a filesystem for Linux that does not support journaling. Its successor, ext3, introduced journaling.

The ipconfig /all output shows the following:

IPv4 Address............ 192.168.0.74Subnet Mask............. 255.255.255.255Default Gateway......... 192.168.0.1

The issue with the subnet mask being set to 255.255.255.255 is that it specifies a single host subnet, meaning the device cannot communicate with other devices on the network or access the internet. The correct subnet mask for a typical home network should be:

Subnet mask of 255.255.255.0: This allows for communication within the same local network (192.168.0.0/24).

Default gateway 192.168.0.1: Correct, this is the typical address for the router.

IPv4 Address 192.168.0.74: Correct, within the correct subnet range.

Changing the subnet mask to 255.255.255.0 will resolve the connectivity issue.

For securing mobile devices with two authentication methods, combining something the user knows (a PIN) with something the user is (biometrics) enhances security by implementing multi-factor authentication.

Smart card: Generally requires additional hardware and is not commonly used in mobile devices.

Biometrics: Uses unique biological traits such as fingerprints or facial recognition, providing a convenient and secure second method of authentication.

Hard token: Involves additional physical devices which might not be practical for mobile devices.

One-time password: Usually used for specific applications rather than as a general device authentication method.

The issue could have been avoided if the developer had used Sandbox testing (Option D), which allows new software to be tested in a controlled environment before implementation. This process ensures that the software does not negatively impact system functionality, like stopping access to critical resources such as file servers.

End-user acceptance (Option A) ensures that users approve the software, but it wouldn't prevent the issue.

Staff delegation (Option B) relates to who is responsible but doesn't address testing.

Appropriate scoping (Option C) helps in defining the extent of changes but does not replace testing.

CompTIA A+ Core 2 References:

4.2 - Explain basic change management best practices, including testing in a sandbox environment​.

The correct answer is Administrative Tools (Option D), which provides access to several system utilities, including those needed for managing system files and settings. Since the user already has local administrator privileges, this would allow them to edit system properties efficiently.

File Explorer Options (Option A) manage general file display settings but do not provide administrative access.

Ease of Access (Option B) is related to accessibility settings, not file management.

Indexing Options (Option C) control how files are indexed for search, but are unrelated to system file editing.

CompTIA A+ Core 2 References:

1.3 - Use features and tools of the Windows operating system, including Administrative Tools​​.

Time Machine is the built-in backup feature for macOS that allows users to back up their system automatically. It continuously backs up everything on the Mac, including files, applications, system files, and settings, allowing users to restore their system to a previous state if needed. Time Machine operates by creating hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for all previous months. Other options like "Mission Control" help in organizing windows, while "System Restore" is a feature more common in Windows operating systems, not macOS.

Comprehensive and Detailed In-Depth Explanation:

Many modern laptops have both an integrated GPU (built into the CPU) and a dedicated GPU (such as NVIDIA or AMD). The system may default to the integrated GPU to save power, which results in poor gaming performance. The technician should manually set the game to use the dedicated graphics card to resolve the issue.

A. Overclock the RAM – Incorrect. While overclocking RAM can improve performance slightly, it does not resolve GPU-related gaming lag.

B. Enable NIC teaming – Incorrect. NIC teaming improves network bandwidth and has no effect on gaming graphics.

D. Activate CPU hyperthreading – Incorrect. Hyperthreading improves multitasking but does not directly impact gaming graphics performance.

Comprehensive and Detailed In-Depth Explanation:

PXE (Preboot Execution Environment) allows a computer to boot from a network server and install a system image remotely. It is commonly used for large-scale deployments because it eliminates the need for physical installation media.

A. ISO – Incorrect. ISO files are used for manual installations, but they do not automate network deployments.

B. Secure – Incorrect. There is no "secure boot process" option for automated deployments. Secure Boot is a security feature.

C. USB – Incorrect. USB boot requires manual installation on each device, making it inefficient for mass deployment.

SSH (Secure Shell) is the secure protocol used for remotely accessing and managing network devices. It encrypts communication, ensuring confidentiality and integrity. Telnet provides remote access but is not secure because it transmits data, including passwords, in plaintext. TKIP is an encryption protocol for Wi-Fi security, not a remote access method. RDP (Remote Desktop Protocol) provides graphical remote desktop access mainly for Windows systems, not typically used for network device management. CompTIA A+ Core 2 clearly indicates SSH as the secure remote access protocol for network device administration.

The first step in securing a newly installed SOHO (Small Office/Home Office) wireless router is to ensure it has the latest firmware installed. Firmware updates often include important security patches and new features that protect the router from known vulnerabilities. Other actions, like disabling unused ports or guest accounts, can be useful for hardening the security, but they should come after the router is running the most recent and secure version of its firmware.

Maintaining a positive attitude and projecting confidence is essential in customer support, especially when the technician is unfamiliar with the specific application. This approach reassures the user and fosters trust. Expressing inexperience (A) may reduce user confidence. Using excessive technical jargon (C) can confuse the user. Simply sending directions (D) might not be sufficient for the user to set up correctly. The Core 2 operational procedures emphasize professionalism, effective communication, and customer service skills as vital components of successful technical support interactions.
