• Question 223:

  During an RFP analysis, one of the vendors mentioned that you'll need to upgrade your Gigabit Ethernet switches to MultiGig switches to ensure support for 802.11ac and 802.11ax, which both offer data rates over 1Gbps. Why is this not sound advice?

  A. Because neither of the technologies support data rates over 1Gbps

  B. Because 802.11ax doesn't support channel bonding

  C. Management overhead that is normal in WLANs will reduce the throughput of the client devices

  D. Because 802.11ac only supports one spatial stream

  Correct Answer: C

• Question 224:

  In a convention center, you have received complaints about the WLAN infrastructure. At this moment, the are only two APs in one auditorium.

  After analyzing the situation, you determined that there are more client devices that the infrastructure was designed for. There are only two APs to support more than 300 devices using the Wi-Fi at the same time.

  What should you do to make the Wi-Fi work as expected?

  Response:

  A. Redesign the entire WLAN

  B. Upgrade the Ethernet connections to MultiGig

  C. Quickly add more APs

  D. Turn up the output power on the APs so that they can handle more clients

  Correct Answer: A

• Question 225:

  iPerf is a tool used in site surveys and validation surveys for what purpose? Response:

  A. RSSI tracking

  B. CCI detection

  C. Throughput testing

  D. Data rate mapping

  E. Signal strength mapping

  Correct Answer: C

• Question 226:

  To increase capacity in a coverage-based wireless network, which of the following techniques are typically recommended?(Choose all that apply.) Response:

  A. Maximize airtime usage by disabling lower data rates.

  B. Add additional APs and use directional antennas.

  C. Turn up power on the access points.

  D. Lower power on the access points and, after careful planning, add more AP

  Correct Answer: ABD

• Question 227:

  What two 802.11 amendments deal with regulatory and transmission requirements? Response:

  A. 802.11k

  B. 802.11i

  C. 802.11d

  D. 802.11f

  E. 802.11h

  Correct Answer: CD

• Question 228:

  An engineering firm just upgraded their WLAN form nine 802.11n APS to nine 802.11ac APs. After this upgrade, they did not see any improvement in throughput. What is the most likely cause of this result? Response:

  A. The APs are still using the 5 GHz lower band

  B. The clients were not upgraded

  C. APs are mounted on the wall

  D. APs are transmitting at a low transmit power

  Correct Answer: B

• Question 229:

  When a WLAN controller sends an 802.11 frame to a lightweight AP for transmission on the wireless medium, how does it mark the frame for 802.11 QoS priority?

  A. The WLAN controller will place the user priority (UP) value in the QoS Control field of the 802.11 frame header before passing it to the lightweight AP.

  B. The WLAN controller does not mark 802.11 frames with priority values only the APs can do this.

  C. The WLAN controller does not mark the 802.11 frames with priority values only the Layer 3 switches can do this.

  D. The WLAN controller does not mark the 802.11 frames with priority values only the Layer 3 routers can do this.

  Correct Answer: A

• Question 230:

  You have determined the best mounting locations for APs in a given installation. The facilities manager has asked you to change the locations for several APs due to aesthetic concerns. You suggest mounting the APs in the ideal locations and painting them so they go unnoticed in the environment.

  What is a valid recommendation or consideration when painting APs?

  A. Always use paints with metallic dye in them to prevent potential RF propagation impact.

  B. Painting APs will significantly reduce the output power.

  C. Painting APs may void the product manufacturer's warranty.

  D. Most AP models for indoor environments come in a variety of form factors and colors. Painting is never recommended.

  Correct Answer: C
