To determine the correct device, we need to understand how a DOCSIS (Data Over Cable Service Interface Specification) network functions in a Small Office/Home Office (SOHO) environment:
C. Cable Modem:
A cable modem is required to convert the signal provided by the ISP (Internet Service Provider) over a DOCSIS network into a format that is usable by the local area network (LAN).
DOCSIS is a standard for high-speed internet over cable television infrastructure, and the cable modem acts as the gateway between the ISP's coaxial network and the LAN.
Without the cable modem, devices in the LAN would not be able to access the internet.
Reference: CompTIA A+ Core 1 Exam Objectives (220-1201), Domain 2.2 C Compare and contrast Internet connection types, network types, and their features.
Incorrect Options:
A. Switch:
A switch is used to connect multiple devices within the LAN. It does not connect the LAN to the ISP's DOCSIS network.
B. Firewall:
While firewalls provide security by managing inbound and outbound traffic, they do not serve as the interface between the ISP and LAN.
D. Router:
A router directs traffic between different networks (e.g., between a LAN and the internet). However, in a DOCSIS network, the cable modem is the device that first connects to the ISP. Many modern cable modems also include built-in routers, but the modem is the primary device needed.
E. Access Point:
An access point provides wireless connectivity within the LAN. It does not connect directly to the ISP or handle DOCSIS signals.
Key Takeaway: The correct device required to interface between the ISP's DOCSIS network and the SOHO LAN is the cable modem.

Modifying duplex settings to double-sided:
Printing on both sides of the paper (duplex printing) reduces paper usage, making it one of the most effective environmentally friendly printing initiatives.
It directly minimizes waste and supports sustainability goals in the workplace.
Incorrect Options:
A. Requiring user authentication for printing: While this can reduce unnecessary or unauthorized printing, it does not directly address environmental objectives like saving resources.
B. Locking down printing to only certain individuals: Limiting access may reduce printing overall, but it does not actively contribute to environmentally friendly practices like duplex printing.
D. Changing the print quality settings to best: Using the "best" print quality increases toner or ink usage, which is counterproductive to environmentally friendly objectives.
Key Takeaway:
Modifying duplex settings to enable double-sided printing is the best initiative to achieve environmentally friendly goals by reducing paper consumption.

정답:
Explanation:
If a print spooler crashes specifically with one application and no issue occurs on other systems, the most likely root cause is a bug within that specific application. Restarting the spooler and reinstalling drivers resolves system-wide or hardware-related issues―not app-specific failures. This indicates the application may be sending malformed print data.

정답:
Explanation:
Reasoning: Projectors have air filters that prevent dust from entering the internal components. A clogged filter can cause the projector to overheat, resulting in shutdowns and even strange smells due to overheating components. Cleaning the filter is a standard troubleshooting step when projectors exhibit overheating symptoms.
Why the Other Options Are Incorrect:
A. Replace the bulb:
While a failing bulb may eventually cause issues, it would not typically result in a strange smell or repeated shutdowns after a fixed period. Bulb issues usually manifest as dim or flickering images.
B. Check the projector configuration:
Configuration settings, such as resolution or input options, would not cause overheating or shutdowns. This option does not address the described symptoms.
D. Adjust the gamma settings:
Gamma settings affect display brightness and contrast but have no impact on overheating or strange smells.
Practical Example:
Dust accumulation in projectors is a common issue, especially in environments with poor air circulation. A clogged filter causes restricted airflow, leading to overheating and automatic shutdowns to protect internal components. Cleaning the filter typically resolves this issue.

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.
Reference: CompTIA A+ Core 1 Exam Objectives (220-1201), Domain 2.5 C Explain basic wired and wireless networking concepts, including ports and protocols. 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.
Reference: CompTIA A+ Core 1 Exam Objectives (220-1201), Domain 2.5 C Explain basic wired and wireless networking concepts, including ports and protocols.
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.
F. Port 443: This port is used for HTTPS (secure web traffic) and is unrelated to email protocols. Key Takeaway: The two correct port numbers associated with email traffic are
B. 25 (SMTP) for sending emails and
D. 110 (POP3) for retrieving emails.
