A.

Larger than 15 dB and yes

B.

Larger than 15 dB and maybe

C.

Larger than 17.5 dB and yes

D.

Larger than 17.5 dB and no

An AP vendor being considered for a WLAN deployment suggests that their 2 4 GHz and 5 GHz dual-band APs use software defined radios What unique capability does this indicate in comparison to non-software defined radios?

A.

At least one radio can be configured for either 2 4 GHz or 5 GHz operations

B.

The radios can have their SSlDs configured through software

C.

Software is used to configure the encryption settings

D.

Software is used to configure the entire WLAN profile

A designer has created a WLAN design that has been implemented in an organization. The network exists in a four-story building Because each floor has an Identical floor plan, the designer designed only one floor and had the installers duplicate the design on each floor. Now. in validation, it is not performing well What best explains the problem caused by this process?

A.

The result was that APs were above and below each other on the same channel, resulting in excessive CCI The APs should have been deployed so that they were not directly above and below each other and so that they used varying channels between floors

B.

The result was that clients could only connect to APs on their floor and, in a multi-floor deployment, you want clients to connect to APs on other floors in case they roam between floors.

C.

The result was that AC) was increased because the APs were deployed above and below each other on the same channels.

D.

The result was that the frequency utilization was too low for the clients to capture RF waves on which to transmit their signals.

When performing a roaming test and packet capture at the same time, what are two particular frames that will be present when roaming between two APs is successful?

A.

Beacon and DTIM

B.

Probe Request and Probe Response

C.

Association Request and Association Response

D.

Reassociation Request and Reassociation Response

During a post-validation survey, you find an area lacking any detectable Wi-Fi signal at all It is located behind an elevator shaft What is a common solution to this problem?

A.

Move one or more APs so that indoor propagation results in coverage in that area or install another AP on that side of the elevator shaft

B.

Turn up the power on the three APs closes! to that area

C.

Install antennas with at least 3 more dB of gain on the two APs closest to that area

D.

Replace all the clients in that area with clients having better receive sensitivity

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

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

After designing a WLAN infrastructure using predictive design software. What's the best way to validate the predictive design in the physical space before deployment, if time and budget allow for it?

Perform an AP-on-a-Stick survey using AP locations based upon the predictive design to confirm each AP's placement.

B.

Deploy all of the APs as they're shown in the predictive design and perform a passive site survey.

C.

Deploy all of the APs as they're shown in the predictive design and perform an active site survey.

D.

Use a client device positioned where the APs will be installed and measure the signal from the client device.
