• Question 93:

  Given:

  In your regulatory domain, a Tx Power Level of "1" is equivalent to 17 dBm.

  For every integer increment (e.g. from 1 to 2) to the Tx Power Level, the APs transmit power is halved.

  In units of mW, what is the actual transmit power for an AP configured at a Tx Power Level of "4"?

  A. 6.25 mW

  Correct Answer: C

• Question 94:

  One of your customers plans on providing wireless coverage to a warehouse facility. After performing an initial walkthrough, you collect the following information:

  The central part of the warehouse is between 400 and 600 feet (122 to 183 meters) from the warehouse switches mounted on the walls.

  The warehouse storage is composed of metallic racks with varying inventory levels and contents, from electronics and plastic toys to food pallets and juice bottles.

  Workers need basic data coverage from their working location, and are not highly mobile. They usually work from one single aisle, and their laptop is on a cart with wheels.

  What would be your one recommendation to provide coverage to the central area of the warehouse?

  A. Equip workers laptops with a directional antenna and install APs less than 328 feet (100m) away from the switch.

  B. In this case, extend the cable length just beyond 328 feet (100 m) and position APs as close as possible to the central area of the warehouse.

  C. Position APs along the walls, and equip the APs with Yagi antennas to cover the central area.

  D. Install APs for client access in the central area and use a mesh backhaul link to connect to the DS.

  Correct Answer: B

• Question 95:

  When designing for a PTP outdoor link, what important consideration should be made about local vegetation?(Choose all that apply.) Response:

  A. Leaves

  B. Tree height growth

  C. Water density

  D. Reflection factor

  Correct Answer: AB

• Question 96:

  An enterprise customer is subject to the highest standards for network uptime. When designing their wireless network, you should consider which of the following?(Choose all that apply)

  Response:

  A. The failover of the wireless network only

  B. The failover of the wired network only

  C. The failover of the wireless and wired network

  D. The physical aspects such as power and cabling

  Correct Answer: CD

• Question 97:

  In this question, you will compare the mobility processes of a network that supports WPA2- Personal and WPA2-Enterprise. Assume the use of a 15-character

  ASCII passphrase for WPA2-Personal and EAP-TTLS/MSCHAPv2 with WPA2-Enterprise. Also, assume that proprietary roaming protocols are not supported.

  When a device transitions from one BSS to another within the same ESS, what step must be performed in the WPA2-Enterprise transition that are not performed in the WPA2-Personal transition?

  A. Open System Authentication

  B. 802.11 Reassociation

  C. 802.1X authentication

  D. 4-Way Handshake

  Correct Answer: C

• Question 98:

  C. All VoWiFi soft phones

  D. All VoWiFi hard phones

  Correct Answer: B

• Question 99:

  Which of the following items could be considered constraints when performing a network design?(Choose all that apply.)

  A. Timeline

  B. Personnel

  C. Politics

  D. Budget

  Correct Answer: ABCD

• Question 100:

  While performing a validation site survey, you realize that overlapping channels are being used on the 2.4 GHz bad due to the automatic channel assignment algorithm of the WLAN infrastructure. What should you do to prevent this?

  A. Reconfigure the automatic channel assignment settings to use only channels 1, 6, and

  B. Purchase and deploy new APs from a different vendor

  C. Reconfigure the network to use static channel plans because automatic channel assignment algorithms are all broken

  D. Leave it as it is; sometimes using all 11 channels in 2.4 GHz gives the optimum performance result

  Correct Answer: A
