Why is it recommended for a wireless network administrator to disable 1 Mbps and 2 Mbps data
rates on the WLAN infrastructure? (Choose two)

When replacing the antenna of a WLAN device with a similar antenna type that has a higher
passive gain, what antenna characteristic will decrease?

What word describes the bending of an RF signal as it passes from one medium to another
medium of a different density?

Given:
ABC Company performs top-secret government contract work and has recently purchased an
802.11 Wireless Intrusion Prevention System (WIPS) to enforce their “NO WIRELESS” network
security policy.
What attack type cannot be recognized by the WIPS?

What answers correctly complete the following sentence?
____________ and ____________ carrier sense functions are used to determine whether the
wireless medium is idle or busy. (Choose 2)

What WLAN system feature is required to produce a scenario with the following configuration on a
single access point? (Choose 2)
1. SSID = Guest / BSSID = AA:AA:AA:AA:AA:AA /
VLAN = 22 / Subnet = 192.168.22.0 / RF Channel = 6
2. SSID = Corporate / BSSID = BB:BB:BB:BB:BB:BB /
VLAN = 33 / Subnet = 192.168.33.0 / RF Channel = 6 / User Type A
3. SSID = Corporate / BSSID = BB:BB:BB:BB:BB:BB /
VLAN = 44 / Subnet = 192.168.44.0 / RF Channel = 6 / User Type B

Given: You are an independent contractor, hired to perform an indoor site survey and network
design for ABC Hotel. The network will support both hotel staff and guest users. You are
interviewing the network manager to determine business, performance, and security requirements
for the future 802.11 WLAN.
What questions should you ask the IT manager? (Choose two)

During the discovery and connectivity process, client and AP stations exchange information about
their supported data rates. After the association, how do client and AP stations select the
supported data rate that will be used to send an 802.11 data frame?

ABC Company has a 2.4 and 5 GHz WLAN deployment supporting four bands in the 5 GHz range
(UNII 1, UNII 2, UNII 2e, and UNII 3). DFS functionality is enabled as required by the regulatory
domain. Band steering is also enabled to encourage dual-band clients to use frequency bands
with more capacity.
Your performance analysis shows that many dual-band VoWiFi client devices will move back and
forth between 2.4 and 5 GHz as the user roams throughout the building. All APs have 2.4 and 5
GHz radios enabled.
This “band hopping” behavior is viewed by network staff to be undesirable. What is the most likely
cause of the unpredictable client band selection behavior?

Given:
You were previously on-site at ABC’s facility to conduct a pre-deployment RF site survey. The
WLAN has been deployed according to your recommendations and you are on-site again to
perform a network validation.
When performing this type of post-deployment RF site survey for VoWiFi, what are two steps that
must be performed? (Choose two)
