CompTIA Updated N10-008 Exam Questions and Answers by dhruv

• The question asks about the best configuration for the WLAN being tested, which involves channel bonding on an 802.11ac AP. Channel bonding is a technique that combines two or more adjacent channels into a wider channel to increase the bandwidth and throughput of the wireless network1.
• The answer is to set up the AP to perform a dynamic selection of the frequency according to regulatory requirements. This means that the AP will automatically choose the best available channel and adjust the transmit power based on the local regulations and the interference level2. This way, the AP can avoid using the channels that are occupied by the government radio system, which may have higher priority and authority over the spectrum3.
• Upgrading the equipment to an AP that supports manual configuration of the EIRP power settings is not the best solution, because it does not address the channel selection issue. EIRP stands for Effective Isotropic Radiated Power, which is the total power radiated by the antenna in all directions. Manual configuration of the EIRP may allow the administrator to increase or decrease the signal strength, but it may also violate the regulatory limits or cause more interference with other devices.
• Switching to 802.11n, disabling channel auto-selection, and enforcing channel bonding on the configuration is also not the best solution, because it may degrade the performance and compatibility of the WLAN. 802.11n is an older standard than 802.11ac, which has lower maximum data rates and fewer features. Disabling channel auto-selection may prevent the AP from adapting to the changing environment and finding the optimal channel. Enforcing channel bonding may increase the bandwidth, but it may also increase the interference and reduce the number of available channels.
• Deactivating the band 5GHz to avoid interference with the government radio is not the best solution, because it may limit the functionality and capacity of the WLAN. The 5GHz band has more channels and less congestion than the 2.4GHz band, which makes it suitable for high-performance applications and devices. Deactivating the band 5GHz may force the WLAN to use only the 2.4GHz band, which may reduce the speed, range, and reliability of the wireless network. References:

Split tunnel is a configuration that allows a remote user to access both the local network and the Internet at the same time. In a split tunnel configuration, only traffic destined for the corporate network is sent through the VPN tunnel, while all other traffic is sent directly to the Internet. This allows the remote user to access the Internet without the company's VPN server being able to monitor or intercept their traffic. Using a split tunnel configuration can help the company to mitigate employee concerns about internet activity being monitored and reassure employees that their private internet activity is not being monitored.

NIC Teaming, also known as load balancing and failover (LBFO), allows multiple network adapters on a computer to be placed into a team for the following purposes: (https://www.bing.com/search?q=what+is+nic+teaming+used+for%3F &form=QBLH&sp=-1&pq=what+is+nic+teaming+used+for&sc=10-28&qs=n&sk=&cvid=13882A9A9B584D8099F4ABCAD034E821&ghsh=0&ghacc=0&ghpl=)

802.11 ax is the latest wireless standard that operates in both the 2.4GHz and the 5GHz bands. It offers higher throughput, lower latency, and improved efficiency compared to previous standards. It also uses technologies such as OFDMA and MU-MIMO to reduce interference and increase capacity in dense environments. Therefore, 802.11 ax is the best choice for a wireless network in an office building with high saturation on both bands.
