CWNA Complete Test Questions 2024. Data Link (MAC and LLC) and Physical (PMD and PLCP) - correct answer What two layers does WLAN technology operate on? 400 ns - increases data rates but not suitable for reflective environments - correct answer Short GI 800 ns - standard, lowers data rates but is more suitable for reflective environments (large warehouses, etc) - correct answer Long GI Frame Aggregation - correct answer Allows for larger frame sizes therefore greater throughput in low ...
