NEW QUESTION 65
You are troubleshooting a client issue on a Windows laptop. The laptop can see and connect to
2.4 GHz APs, but it does not even see 5 GHz APs. While evaluating the issue, you determine that this problem is happening for all of the laptops of this model in the organization. Several other tablets connect on channel 48 and channel 52 in the same work areas. What is the likely problem?
- A. The clients are configured to use WPA and 5 GHz channels only support WPA2
- B. The access points are configured to disallow 5 GHz
- C. The client drivers are faulty and should be upgraded
- D. The antennas in the laptops have insufficient gain to detect the 5 GHz signals
Answer: D
NEW QUESTION 66
A client complains of low data rates on his computer. When you evaluate the situation, you see that the signal strength is -84 dBm and the noise floor is -96 dBm. The client is an 802.11ac client and connects to an 802.11ac AP. Both the client and AP are 2x2:2 devices. What is the likely cause of the low data rate issue?
- A. Too few spatial streams
- B. Lack of support for 802.11n
- C. Weak signal strength
- D. CAT5e cabling run to the AP
Answer: C
NEW QUESTION 67
Three access points are used within a facility. One access point is on channel 11 and the other two are on channel 1. The two access points using channel 1 are on either side of the access point using channel 11 and sufficiently apart so that they do not interfere each other when they transmit frames. Assuming no other Aps are in the vicinity, is CCI still a possibility in this network and why?
- A. No, because CCI only occurs in the 5 GHz frequency band
- B. No, because the Aps are far enough apart that no CCI will occur
- C. Yes, because channel 11 loops around and causes CCI with channel 1
- D. Yes, because the client devices connected to one of the channel 1 APs will transmit frames that reach the other channel 1 AP as well as
Answer: D
