You support a WLAN using dual- band 802.11ac three stream access points. All access points have both the 2.4 GHz and 5 GHz radios enabled and use 40 MHz channels in 2.4 GHz. A manager is concerned about the fact that each access point is connected using a 1 Gbps Ethernet link. He is concerned that the Ethernet link will not be able to handle the load from the wireless radios. What do you tell him?
- A. Due to 802.11 network operations and dynamic rates used by devices on the network, the two radios will likely not exceed the 1 Gbps Ethernet link .
- B. His concern is invalid because the AP will compress all data before transmitting it onto the Ethernet link.
- C. His concern is valid and the company should upgrade all Ethernet link to 10 Gbps immediately.
- D. His concern is valid and the company should immediately plan to run a second 1 Gbps Ethernet link to each AP.
Answer: C
NEW QUESTION 93
XYZ Company has decided to install an 802.11 WLAN system that will support 1000 wireless users, but they are concerned about network security. XYZ is interested in deploying standardized security features. In addition to WPA2-Enterprise with PEAP and role-based access control, XYZ would like to support management frame protection as well as a fast secure roaming protocol for future mobile handsets.
As XYZ Company selects a product to deploy, what two IEEE amendments, which are included in
802.11- 2016, should be supported to provide the management frame protection and fast secure roaming security features?
- A. 802.11j and 802.11k
- B. 802.11z and 802.11w
- C. 802.11r and 802.11k

Answer: D
NEW QUESTION 94
You are the network administrator for ABC Company. Your manager has recently attended a wireless security seminar. The seminar speaker taught that a wireless network could be hidden from potential intruders if you disabled the broadcasting of the SSID in Beacons and configured the access points not to respond to Probe Request frames that have a null SSID field.
Your manager suggests implementing these security practices. What response should you give to this suggestion?
- A. This security practice prevents manufacturers' client utilities from detecting the SSID. As a result, the SSID cannot be obtained by attackers, except through social engineering, guessing, or use of a WIPS.
- B. Any tenants in the same building using advanced penetration testing tools will be able to obtain the SSID by exploiting WPA EAPOL-Key exchanges. This poses an additional risk of exposing the WPA key.
- C. Any 802.11 protocol analyzer can see the SSID in clear text in frames other than Beacons frames. This negates any security benefit of trying to hide the SSID in Beacons and Probe Response frames.
- D. To improve security by hiding the SSID, the AP and client stations must both be configured to remove the SSID from association request and response frames. Most WLAN products support this.
Answer: C
NEW QUESTION 95
