CWNA-107 CWNP Exam Questions and Free Practice Test

Question 7

You administer a small WLAN with nine access point. As a small business, you do not rum a RADIUS server and use WPA2-Personal for security. Recently, you changed the passphrase for WPA2-personal in all Aps and clients. Several users are now reporting the inability to connect to the network at time and it is constrained to one area of the building. When using scanner, you see that the AP covering that area is online

A. The AP that covers the problem area requires a firmware update

B. The clients are improperly configured

C. The AP that covers the problem area has failed

D. The AP that covers the problem area is improperly configured

Correct Answer:A

Question 8

The IEEE 802.11-2016 standard requires VHT capable devices to be backward compatible with devices using which other 802.11 physical layer specification (PHY)?

A. ERP-PBCC

B. DSSS

C. OFDM

D. HR/DSSS

Correct Answer:C

Question 9

What Linux shell command can be used to view the hardware and PHY capabilities of a wireless adapter in detail including channel widths, output power setting, channels supported, and more?

A. ifconflg

B. iw phy

C. netsh wlan show device

D. iwconflg

Correct Answer:D

Question 10

As an RF wave propagates through space, the wave front experiences natural expansion that reduces its signal strength in an area. What term describes the rate at which this expansion happens?

A. Inverse square law

B. Ohm’s law

C. Fresnel zone thinning

D. MU-MIMO

Correct Answer:A

Question 11

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. His concern is valid and the company should upgrade all Ethernet link to 10 Gbps immediately.

B. His concern is valid and the company should immediately plan to run a second 1 Gbps Ethernet link to each AP.

C. 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 .

D. His concern is invalid because the AP will compress all data before transmitting it onto the Ethernet link.

Correct Answer:D

Question 12

What phrase defines Equivalent Isotropically Radiated Power (EIRP)?

A. Power supplied from the transmission line to the antenna input

B. The power output from the radio after cable losses

C. The power output from the radio into the RF cable

D. The highest RF signal strength that is transmitted from a given antenna

Correct Answer:D
