   A warehouse is designing a WLAN for its inventory management system. The warehouse has tall metal shelving that can obstruct Wi-Fi signals. The system uses handheld scanners that move throughout the warehouse. The design team must ensure reliable coverage in all aisles. Which design consideration is most important for this environment?

   • AUse a mesh network to extend coverage without running cables to every AP.
   • BIncrease the transmit power of a few APs to cover the entire warehouse.
   • CPlace APs in the ceiling at the ends of aisles to provide line-of-sight coverage.
   • DPosition APs along the aisles, possibly at lower heights, to minimize obstruction by metal shelving.

   A hospital's WLAN is used for critical medical devices and staff communications. The network team has set up monitoring and alerts. During a routine check, they notice that one AP has a high error rate and is causing client disconnections. What should the team do to maintain the WLAN's reliability?

   • ATroubleshoot the AP by checking logs, interference, and cabling.
   • BDisable the AP and rely on neighboring APs for coverage.
   • CReplace the AP immediately without further investigation.
   • DIncrease the transmit power of the AP to improve signal quality.
