Introduction to Basic Service Set (BSS) Answers 1. What is a primary benefit of using multiple Basic Service Sets (BSSs) in a network? A. Improved reliability through redundancy B. Increased latency for devices C. Reduced security measures D. Higher resource contention Answer: Improved reliability through redundancy (A) Multiple BSSs provide a way to create redundancy that can help handle network outages and interference. 2. Which consideration is important for preventing interference from neighboring networks in BSS design? A. Limiting access point security B. Choosing the appropriate channel C. Implementing channel bonding D. Maximizing SSID broadcasting Answer: Choosing the appropriate channel (B) Selecting the right channel helps avoid interference with other networks and enhances performance. 3. How do separating devices into different BSSs influence network performance? A. It increases congestion and latency B. It eliminates the need for security measures C. It allows for resource contention among all devices D. It leads to reduced congestion Answer: It leads to reduced congestion (D) Separating devices reduces congestion and improves overall network performance by minimizing resource contention. 4. What security measure can be implemented at a BSS level to enhance network protection? A. Allowing open access to all devices B. Disabling SSID broadcasting C. Using WPA2/3 encryption D. Limiting channel bandwidth Answer: Using WPA2/3 encryption (C) WPA2/3 encryption is a crucial measure for protecting network traffic at the BSS level. 5. What is the purpose of power control in BSS design? A. To ensure all devices connect to the same access point B. To eliminate the need for separate BSSs C. To optimize range and prevent interference D. To maximize output power at all times Answer: To optimize range and prevent interference (C) Power control is used by access points to adjust their output power for better range and to avoid interference. 6. What core function does the access point (AP) serve in a Basic Service Set (BSS)? A. Regulates the power output of wireless stations B. Acts as a central hub for communication C. Generates unique Service Set Identifiers (SSID) for each client D. Establishes connections among users directly Answer: Acts as a central hub for communication (B) The AP is the central point for communication within a BSS, coordinating interaction among wireless stations. 7. Which of the following statements is true about the structure of a Basic Service Set (BSS)? A. A BSS operates in infrastructure mode with a single AP B. A BSS uses overlapping channels to extend its range C. A BSS functions in ad-hoc mode without centralized control D. A BSS includes multiple access points for redundancy Answer: A BSS operates in infrastructure mode with a single AP (A) A BSS operates in infrastructure mode, relying on one access point for managing connectivity and communication. 8. What is a key characteristic of a Basic Service Set (BSS) in comparison to an Independent Basic Service Set (IBSS)? A. A BSS is limited in scalability compared to an IBSS B. A BSS is entirely decentralized in its operation C. A BSS operates without any access points D. A BSS has higher reliability than an IBSS Answer: A BSS has higher reliability than an IBSS (D) A BSS has higher reliability due to its infrastructure mode, which involves a central access point. 9. What process occurs after a device successfully authenticates to join a BSS? A. Direct transmission of data B. Network disconnection C. Association Completion D. De-authentication Answer: Association Completion (C) After a device is authenticated, it undergoes Association Completion to officially join the BSS. 10. Which of the following best describes the limitations of a BSS? A. Unrestricted range due to enhanced power output B. Unlimited direct communication among all wireless stations C. Dependence on the environment and AP power for range D. Inherent capacity to connect an indefinite number of clients Answer: Dependence on the environment and AP power for range (C) The range of a BSS is limited, affecting its operational capacity based on environment and access point power. 11. What is the primary advantage of network segmentation through BSSs? A. Increased cost of network management B. Limitations on client device connectivity C. Enhanced security and improved network performance D. Wider network coverage without performance improvements Answer: Enhanced security and improved network performance (C) Segmenting the network into BSSs enhances security measures and optimizes performance. 12. Which component enables wireless communication on client devices within a BSS? A. Modulating Transmitters B. Signal Amplifiers C. Network Interface Cards (NICs) D. Access Point (AP) Answer: Network Interface Cards (NICs) (C) Network Interface Cards (NICs) are the hardware components that allow client devices to communicate wirelessly. 13. In a BSS, how do wireless stations communicate with one another? A. Through the access point facilitating the data transmission B. Directly without any central control C. Creating an independent ad-hoc network for interactions D. Using an external server to manage their communication Answer: Through the access point facilitating the data transmission (A) Stations within a BSS communicate through the access point, which facilitates data transmission between them.
