NFC (Near-Field Communication) is a subset of RFID technology designed for very short-range wireless communication, typically within a few centimeters. It is primarily used for contactless transactions, like mobile payments, and can also support peer-to-peer data exchanges. NFC operates at 13.56 MHz and enables devices to communicate when placed near each other.

A smart card provides an additional factor of authentication by storing secure credentials, such as certificates, that cannot be guessed or replicated. It complements user accounts and is "something you have".

Why Not A (Fingerprint reader): This is "something you are", but the scenario specifically requires a physical token.

Why Not C (Secure token): Secure tokens are also valid but may not integrate as seamlessly into multi-factor authentication for physical and system access.

Why Not D (NFC scanner): An NFC scanner is a device and not a token itself; it reads cards or other credentials.

Assigning astatic IP addressto a network printer ensures it always retains the same address, allowing users and print servers to consistently reach it even after a reboot or network refresh.

Option B (Private address):Refers to address ranges (e.g., 192.168.x.x) — doesn't guarantee address persistence.

Option C (Wi-Fi):Is a connection method, not a method of IP assignment.

Option D (Dynamic addressing):Via DHCP, which can change over time unless reservations are made (less reliable).

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.4: Given a scenario, install and configure printers.

A firewall monitors and filters incoming and outgoing network traffic based on security rules, protecting the network from unauthorized access and threats.

Why Not A (Switch): A switch connects devices within a network but does not monitor or filter traffic.

Why Not B (Access point): An access point provides Wi-Fi connectivity but does not filter traffic.

Why Not D (Hub): A hub simply broadcasts data to all connected devices without filtering traffic.
