Scan-to-email functions rely on the printer sending scanned documents to an email server. CompTIA A+ identifies SMTP (Simple Mail Transfer Protocol) as the protocol responsible for sending email messages from clients to mail servers. When configuring scan-to-email, the technician must enter:

SMTP server address

Authentication credentials

Port number (25, 465, or 587)

Encryption type (TLS/SSL)

Without SMTP, the printer cannot transmit emails.

SMS (A) refers to text messaging. SFTP (C) is secure file transfer, common for scan-to-folder workflows, not email. SMB (D) is used for Windows file sharing.

Therefore, the correct protocol is SMTP.

An internal cloud platform operated exclusively for a single organization is a private cloud, providing dedicated resources and enhanced control.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.7 – Cloud models:

“A private cloud is provisioned for exclusive use by a single organization, typically managed internally or by a third party, and may be hosted on-premises.”

A valid public IP address must fall outside the private IP address ranges:

10.0.0.0 to 10.255.255.255

172.16.0.0 to 172.31.255.255

192.168.0.0 to 192.168.255.255

66.157.195.20 is outside these ranges, making it a public IP address.

Why Not A, C, D: These IPs fall within private IP address ranges.

CompTIA A+ Exam Reference: Core 1 (220-1201), Section 2.6, IP addressing​.

Amaintenance kitfor a laser printer often includesrollers, fuser, and other partsthat wear out over time. If the printer issmudging and misfeeding, it's a sign thatmultiple components are failing, which a maintenance kit is designed to resolve.

Option A (Fuser):May cause smudging if it's not heating correctly, but it won’t resolve paper misfeeds alone.

Option C (Corona wire):Can cause poor image quality if dirty but doesn’t affect paper feeding.

Option D (Toner cartridge):Can cause streaks if defective, but not paper feed issues.

CompTIA A+ Core 1 Exam Objective Reference:

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

Excessive heat buildup due to insufficient cooling is a primary cause of unexpected shutdowns. A high-performance heat sink improves thermal transfer, dissipates more heat, and helps maintain CPU temperature within safe limits. When CPU temperatures reach levels like 208°F (98°C), the system may shut down to prevent damage.

In Wi-Fi, the 2.4GHz band contains 14 total channels (depending on region), but only channels 1, 6, and 11 are considered non-overlapping in most countries. CompTIA A+ highlights the importance of selecting these channels to minimize interference, especially in environments with multiple wireless networks or access points.

The 2.4GHz band is narrower than 5GHz, causing adjacent channels to overlap significantly. Using channels 1, 6, and 11 prevents overlap and reduces signal interference, improving performance and stability.

5GHz (B) has many non-overlapping channels and does not use the 1/6/11 scheme. The 6GHz band (C) is part of Wi-Fi 6E and uses entirely different channel planning. The 60GHz band (D) supports short-range high-speed connections like WiGig, not traditional Wi-Fi channels.

Therefore, the 2.4GHz band is the correct answer.

Identifying changes made to the system is the next step to troubleshoot why an application no longer launches, as recent changes often cause such issues.

Why Not A (Research the symptoms): Research is broader and should come after identifying changes.

Why Not C (Determine which steps need to be performed): This comes after identifying the issue.

Why Not D (Check the vendor's website): This is a later step if further guidance is needed.

CompTIA A+ Exam Reference: Core 2 (220-1102), Section 3.1, troubleshooting methodology​.

ANetwork Interface Card (NIC)is the hardware responsible for network connectivity. If the NIC is failing or underperforming (e.g., due to a bad driver, hardware fault, or misconfiguration), it can causeslow or unstable network speeds.

Option A (CPU):A failing CPU affects overall system performance but not specifically network speed.

Option C (HDD):A slow hard drive causes application lag, but not poor network performance.

Option D (RAM):Affects multitasking and speed, not network throughput.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.5: Given a scenario, troubleshoot problems related to wired and wireless networks.
