1. A home user is experiencing poor signal quality on their cable television. After troubleshooting, the technician suspects an issue with the cable connection. Which connector type is commonly used for cable TV connections, and what should the user check first?
The F type connector is commonly used for cable TV connections. The user should first check the F type connectors on both ends of the coaxial cable for tightness and any signs of damage to improve signal quality.
2. A system administrator is configuring email client settings for a user who needs to access emails from multiple devices. The administrator wants to ensure that the user can retrieve emails from the server while keeping them stored on the server for future access. Which protocol and port combination should be configured on the email client to achieve this?
Post Office Protocol version 3 (POP3) uses TCP port 110 for retrieving emails from the server. Unlike UDP, TCP is connection-oriented and ensures reliable communication. Configuring the email client with TCP port 110 allows the user to download emails from the server while keeping them stored, enabling future access from multiple devices.
3. A graphic design company is upgrading its desktop computers to handle resource-intensive design software. The IT team is selecting CPUs for the desktops to ensure optimal performance during graphic design tasks. In this scenario, which CPU feature should the team prioritize to enhance the responsiveness of the design software?
For desktop computers running resource-intensive graphic design software, prioritizing CPUs with multiple cores is crucial. Graphic design tasks often benefit from parallel processing, and a multi-core CPU enables the system to handle multiple threads simultaneously, enhancing responsiveness and overall performance during complex design operations.
4. A user consistently experiences paper jams in a laser printer, particularly when using thicker paper for important documents. The technician rules out any obstructions and verifies that the paper tray settings match the paper type. What is the MOST LIKELY cause of the recurring paper jams?
The correct answer is B) Worn-out pickup rollers. Thicker paper requires more traction from the pickup rollers to feed correctly. Worn-out rollers may slip or fail to grip the paper, resulting in frequent jams. Incorrect paper size settings, outdated printer firmware, and insufficient printer memory are less likely to cause issues specifically with thicker paper.
5. A network technician is setting up a new data center and needs to connect multiple cables to a central termination point efficiently. Which of the following connectors or features would be most appropriate for this purpose?
In this scenario, the most appropriate choice is the Punchdown block. A Punchdown block serves as a central termination point for multiple cables, allowing for organized and efficient connectivity.

6. An organization is implementing a print server to centrally manage printing tasks for multiple multifunction printers. What benefit does this centralized approach provide in terms of security?
Implementing a print server enhances access control (Option C) by allowing administrators to manage user permissions centrally. This ensures that only authorized users can send print jobs to the multifunction printers, improving overall security.
7. A medium-sized company is facing issues with email phishing attacks, and the IT team is exploring options to enhance email security. They decide to implement DomainKeys Identified Mail (DKIM) to mitigate the risks. In this scenario, what is the primary role of DKIM in preventing phishing attacks?
DKIM digitally signs outgoing email messages, providing a mechanism for the recipient to verify that the message was actually sent by the claimed sender and that it has not been altered in transit. This helps in preventing phishing attacks by ensuring the legitimacy of the sender. The other options are not the primary role of DKIM in this context.
8. A large organization is implementing DHCP for its network, and the IT team wants to ensure that specific devices receive consistent IP addresses for management purposes. In this scenario, what is the most appropriate use of DHCP reservations?
DHCP reservations allow specific devices to receive a consistent, predetermined IP address based on their unique MAC addresses. This is valuable for devices that require a static-like IP address assignment while still benefiting from DHCP management. The other options are not the primary use of DHCP reservations in this context.
9. A user is troubleshooting their laptop's near-field scanner feature, which is not functioning properly. The scanner is unable to read NFC tags even when placed directly on the designated area. What is the MOST likely cause of this issue?
The most likely cause of a near-field scanner failing to read NFC tags is interference from nearby electronic devices. Electronic interference can disrupt the communication between the scanner and the NFC tags. While insufficient power or outdated drivers can cause issues, interference is the primary consideration in this scenario.
