220-1101 Exam Dumps - CompTIA A+ Certification Exam: Core 1

Two-factor authentication (2FA) significantly enhances security by requiring two forms of verification before granting access to company resources, making it harder for unauthorized users to gain access even if they have one of the credentials. PIN code enforcement adds an additional layer of security by ensuring that devices are protected by a PIN, making physical access to the device more challenging for unauthorized users. While the other options provide various benefits, 2FA and PIN code enforcement directly enhance the security of remote users accessing company resources.

A DHCP lease is a temporary assignment of an IP address and other network configuration parameters (such as DNS and gateway) to a device. The lease is renewed periodically to maintain the assignment.

Why Not A (A definition of the scope of addresses): The DHCP scope defines the range of IP addresses but is not the lease itself.

Why Not B (A reservation of an IP configuration): DHCP reservations ensure a specific device always receives the same IP address, but this is not the lease.

Why Not D (A translation of network names to IP addresses): This describes DNS, not DHCP.

When a user consistently receives an error requesting A4 paper for print jobs, and no other users are experiencing similar issues, it indicates a possible misconfiguration in the user's printer settings. By setting the printer defaults in the Control Panel to use letter-sized paper, which is more common in some regions, this ensures that the user's print jobs are aligned with the available paper size in the office printer. This approach addresses the root cause of the issue by ensuring that the default settings match the paper size used in the office, eliminating the need for the user to adjust settings for each print job.

A sandbox in virtualization allows testing an application in an isolated environment to observe its behavior without affecting the host system.

Why Not A (Run an application on multiple workstations): This describes application virtualization, not sandboxing.

Why Not C (Migrate a legacy application): This is about virtualization for legacy support, not testing.

Why Not D (Create a firewall): A firewall does not act as a sandbox for application testing.

CompTIA A+ Exam Reference: Core 1 (220-1101), Section 4.2, virtualization and sandboxing​.

A hotspot provides a redundant internet connection using cellular data. This ensures connectivity for the meeting even if the primary ISP connection fails.

Why Not A (Wireless access point): A wireless access point expands Wi-Fi connectivity but does not provide internet redundancy.

Why Not B (Near-field communication): NFC is used for short-range communication, not internet connectivity.

Why Not D (Bluetooth): Bluetooth is for short-range device pairing and cannot serve as a backup internet connection.

CompTIA A+ Exam Reference: Core 1 (220-1101), Section 2.7, internet connection types and redundancy​.

NFC (Near Field Communication) devices commonly authenticate users through methods like badging, where a user’s badge or ID card, enabled with NFC, grants access. Passwords and passcodes are not NFC methods, while biometrics are typically used in high-security areas with specific hardware. NFC’s authentication, as outlined in the CompTIA A+ Core 1 objectives, facilitates access in environments needing convenient user verification.

A significant increase in the number of reallocated sectors on a hard drive is a clear indication that the drive is experiencing physical damage or wear and tear that cannot be repaired through software means. Reallocated sectors are bad sectors that the drive's firmware has marked as unusable and moved data to spare sectors. This is often a precursor to drive failure. Therefore, the most prudent next step is to replace the hard drive to ensure data integrity and system reliability.
