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.

Firmware is the embedded software on a device such as a printer. Manufacturers often release firmware updates to resolve hardware-specific functionality issues, such as scan-to-email or security vulnerabilities.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.4 -- Printer installation and maintenance:

''Firmware updates provide bug fixes and add new features for multifunction printers. Apply firmware updates to resolve device-specific issues.''

Cellular networks offer broad coverage in rural or less populated areas where laying fiber, cable, or DSL lines may not be feasible or cost-effective. Cellular broadband (4G LTE/5G) provides fast speeds using existing mobile network infrastructure.

From CompTIA A+ 220-1101 Official Study Guide, Objective 2.7 -- Compare and contrast Internet connection types:

'Cellular connections offer high speed and extensive coverage, especially in areas where other wired infrastructure may not exist or be practical.'

Comprehensive and Detailed Step-by-Step

To answer this question, we need to identify the port numbers associated with email protocols used in client-server communication.

Port 25 (SMTP - Simple Mail Transfer Protocol):

This port is primarily used for sending emails between mail servers and from mail clients to mail servers (sending outbound mail).

SMTP is an essential protocol for email traffic.

Port 110 (POP3 - Post Office Protocol v3):

POP3 is used for retrieving emails from a mail server. It is commonly used for downloading email messages to a local client, after which the messages are deleted from the server.

While not as commonly used today (due to IMAP being preferred), POP3 is still a recognized email protocol, and its association with port 110 makes it a valid answer.

Incorrect Options:

A . Port 23: This is the Telnet protocol used for remote terminal access. It is not related to email traffic.

C . Port 67: This port is associated with the DHCP (Dynamic Host Configuration Protocol) server-to-client communications. It is unrelated to email.

E . Port 137: This port is part of NetBIOS, used for name resolution in legacy Windows environments. It is not relevant to email traffic.
