Exam 300-425 topic 1 question 176 discussion

Actual exam question from Cisco's 300-425

Question #: 176
Topic #: 1

A hospital wireless environment was designed with these characteristics:
• RF coverage
• better than -67 dBm in the 5 GHz spectrum
• RRM be used for DCA and TPC in the 2.4 GHz band
• RRM be used for DCA and TPC in the 5 GHz band

After deployment, why do many of the legacy 802.11b/g devices have difficulty maintaining connectivity?

A. Excessive co-channel interference in the 2.4 GHz band exists.
B. Excessive overlapping channels in the 2.4 GHz band exists.
C. TPC drastically increases Tx power in the 2.4 GHz band.
D. TPC drastically reduces Tx power in the 2.4 GHz band.

Selected Answer: D

D is correct. Considering these are legacy 802.11b/g devices, they may have less sensitive receivers so if TPC reduces TxP too much in 2.4 GHz, the result is insufficient signal strength causing them to be unable to maintain strong enough connection to the APs.

Selected Answer: A

Option A is more likely because co-channel interference directly impacts connectivity by increasing noise and contention, while TPC adjustments (Option D) are typically controlled to maintain adequate coverage.

There's RRM configured here w/c helps manage CCI rather than cause connectivity issues.
