100-140 Question 191
Single answerA company is setting up a new office and needs to decide between using a LAN (wired) connection or a WLAN (wireless) connection for the majority of its employees. The IT manager lists the following requirements:
- High-speed data transfer for large file sharing between employees.
- Minimal signal interference from other devices in the office.
- Cost-effectiveness in setup and scalability for future growth.
Based on these requirements, which connection type would be the most suitable?
- A
LAN, as it provides high-speed and interference-free connections, but may have higher setup costs.
- B
WLAN, as it is cost-effective, easy to scale, and offers the fastest data transfer speeds.
- C
LAN, as it is cost-effective, scalable, and provides the fastest data transfer speeds.
- D
WLAN, as it provides high-speed and interference-free connections, but may have higher setup costs.
Show answer and explanation
Correct answer: A
Explanation
LAN (wired) connections are ideal for scenarios requiring high-speed data transfer and minimal interference, making them suitable for environments where performance is a priority. However, they typically involve higher setup costs due to cabling and infrastructure requirements. WLAN (wireless) connections are more cost-effective and scalable but are more prone to interference and generally offer lower data transfer speeds compared to wired connections.
- A. Correct.
Correct. LAN is typically the best choice for high-speed data transfer and minimal interference, though it may require higher initial setup costs for cabling and infrastructure.
- B. Incorrect.
Incorrect. While WLAN is cost-effective and scalable, it does not provide the highest data transfer speeds, and it is more prone to signal interference.
- C. Incorrect.
Incorrect. While LAN does provide fast data transfer speeds, it is usually not considered cost-effective or easily scalable compared to WLAN.
- D. Incorrect.
Incorrect. WLAN does not provide interference-free connections, as it is more susceptible to interference from other wireless devices or physical obstacles.
