Answer - C - The disadvantage associated with using a number of access points in the Repeater Mode in series is that users attached to the repeater access point will experience high latencies.

Key Takeaway: A WLAN repeater does not physically connect by wire to any part of the network. Instead, it receives 802.11 frames from an access point, an end-user device, or another repeater and retransmits the frames. A downside of wireless repeaters is that they reduce throughput on the WLAN. Because the repeater must receive and retransmit each frame on the same RF channel, it effectively doubles the number of frames that are sent. This problem compounds when using multiple repeaters because each repeater will duplicate the number of frames sent. This latency may make it impossible to use real-time audio or video applications.
