In response to a security breach involving compromised credentials, one-time tokens provide an effective method to enhance authentication security. These tokens are part of multi-factor authentication (MFA) and generate unique codes for each login attempt, ensuring that even if credentials are stolen, unauthorized access is prevented.
* Why One-time Tokens?
* One-time tokens are dynamic and expire after a single use, significantly reducing the risk of unauthorized access even if usernames and passwords are compromised.
* Often delivered through apps like Google Authenticator, hardware tokens, or SMS.
* Incorrect Options:
* A. Biometric authentication: While secure, it may not address all scenarios and requires additional hardware.
* B. Peer-reviewed log-ins: Not a valid security measure.
* C. Log-in scripts: Used for automating login configurations but do not enhance security directly.

Port 21 is used by FTP (File Transfer Protocol) for file transfers. Port 53 is for DNS, port 68 is for DHCP, and port 389 is for LDAP. Understanding standard network ports is essential in CompTIA A+ Core 1 objectives, especially in networking and troubleshooting scenarios.

To connect printers without an RJ45 port to the network, the technician needs to enable wireless connectivity.
By configuring the printers to connect to the network wirelessly, the company can achieve the desired consistency in printer configuration across the office. This approach allows printers without built-in wired network capabilities to be part of the network, facilitating shared access and remote printing functionalities.

NFC (Near Field Communication) is a wireless communication technology that is commonly used for contactless payments, mobile payments, and other mobile transactions. It allows two devices to communicate with each other when they are placed in close proximity.
Contactless payments commonly use NFC (Near Field Communication). NFC is a wireless communication technology that allows two devices to communicate with each other when they are in close proximity.
Contactless payments use NFC to enable customers to make payments by simply tapping their contactless card or mobile device on a payment terminal.
