Question 1
Single choice

Of the following antenna connector types, which one is the smallest?

A.

RP-TNC

B.

MC Connector

C.

N Connector

D.

Male N Connector

Question 2
Single choice

What is the DSCP Per Hop Behavior equivalent classification of the 802.11 AC_VO priority level?

A.

AF31

B.

CS3

C.

VO

D.

EF

Question 3
Single choice

ABC Manufacturing has a heavily-used dual-band (2.4 / 5 GHz) WLAN, but sporadic RF interference across the 2.4 GHz band is causing dropped VoWiFi calls and leading to data connectivity and throughput problems.

In addition to avoiding 2.4 GHz channels and installing a distributed spectrum analyzer to locate RF interference sources, what should the implementer do to resolve the problem fully?

A.

Have only guest access on the 5 GHz channels.

B.

Move all corporate data clients and VoWiFi devices to the 5 GHz channels appropriate for their regulatory domain.

C.

Use captive portals for guest authentication in 5 GHz.

D.

Implement WPA-PSK everywhere in the network.

Question 4
Single choice

Given: In a site survey deliverable report, you are expected to explain the spectrum measurements taken at the customer's site.

What portion of a spectrum analyzer view can be used to determine if a given channel is too active for use as the active channel for a new AP?

A.

Device list

B.

Frame decode

C.

Real time FFT

D.

Duty cycle

Question 5
Single choice

During a post-deployment verification, you are requested to troubleshoot an area where users are experiencing poor throughput. They are using data communication only, mainly from laptops. You captured the frame showing an incorrect FCS. This frame is typical of those thatwere captured by the analyzer.

What does this frame reveal about the RF network in this area?

A.

One station seems to be streaming video, thus may have reserved significant bandwidth via admission

control

B.

Contention Free is in place in this network, which may starve some non-QoS stations from access

C.

Multipath or excessive collisions seem to be an issue in this area

D.

The AP seems to be too far to provide enough coverage to this area

Question 6
Single choice

In a large enterprise (5000+ wireless users), by what would NOT be a recommended method by which IP addresses and VLANs are assigned to different clients associated to the same AP?

A.

Each SSID is mapped to a static VLAN assignment

B.

Upstream AAA servers dynamically assign VLANs to each user or group profile

C.

Radio signal metrics (RSSI, SNR, etc.) of WLAN clients are triangulated for location-based VLAN assignment during association

D.

Multiple VLAN pools are designated for an SSID and user IP addresses are selected in a round-robin fashion from the associated pools

Question 7
Single choice

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

Question 8
Single choice

What statement is true of a WLAN design that supports Real-Time Location Services (RTLS) with 802.11 RFID asset tags?

A.

When passive tags are implemented, the AP density should be increased by 25% to make up for the shorter transmit range of passive tags as compared to active tags.

B.

Active RFID tags periodically transmit 802.11 beacon management frames that must be synchronized with the AP for proper location of the tagged asset.

C.

With passive tags, AP transmit gain should be increased to supply extra power for near-field coupling or backscatter modulation from the tag to the AP since the passive tag lacks an internal power source.

D.

Passive tags do not communicate directly with the WLAN infrastructure, but instead they rely on the tag reader to communicate tag information to the infrastructure's location tracking server/database.

Question 9
Single choice

You desire to achieve a 450 Mbps MCS. What 802.11n features (from the numbered list below) are required?

1. Frame aggregation

2. Short GI

3. 40 MHz channels

4. 2 spatial streams

5. 3 spatial streams

6. Transmit beamforming (TxBF)

A.

2,3,2

B.

1, 2, 3, 5

C.

1, 2, 3, 4, 6

D.

2,3,5

Question 10
Single choice

Given:As the wireless network administrator for XYZ Company, you are planning to upgrade your aging wireless network infrastructure, as well as some clients, to support 802.11ac. In your research, you have discovered that your new wireless client devices and infrastructure are 802.11ac, WMM, and WMM-PS certified by the Wi-Fi Alliance. Some of your existing client devices are 802.11a/b/g devices that do not support WMM.
Given this information, what scenario is possible when your company's employees begin using both types of client devices on the new WLAN?

A.

All WMM-PS certified client devices will be prevented from utilizing WMM-PS features until all stations in use on the wireless medium are WMM-PS certified.

B.

The WLAN infrastructure will set the dozing times of the WMM-PS certified client devices based upon their WMM access category, while the non-WMM-PS client devices will continue to use PS-Poll frames.

C.

Performance and battery life will be inconsistent between WMM-PS and non-WMM-PS client devices when used with applications that support WMM-PS.

D.

WMM-PS enabled APs will allow both WMM-PS and non-WMM-PS stations to use the trigger-and-delivery mechanism, but WMM-PS stations will get priority.
