NEW QUESTION 2
An engineer is preparing for an active site survey of a hospital and is informed that he or she should not enter any active surgery suites.
Which option describes how the engineer should address this restriction?

• A. Conduct a passive wireless survey in the restricted areas.
• B. Use the predictive AP placement tool on the wireless controller
• C. Skip the area and estimate where to place the access points.
• D. Arrange to perform survey activities after hours.

Answer: A

Explanation: Passive Survey
Passive surveys are surveys that are performed with a listen-only mode. The survey client never associates to the access point (AP). Such surveys can be helpful when you look for rogue devices or you want a good gauge of downlink RF coverage from the infrastructure devices. These can be accomplished with a passive survey.

NEW QUESTION 3
During a post-deployment survey, the wireless engineer notices that offices in surrounding suites also have wireless networks and the 2.4 Ghz band is highly utilized Which configuration must the engineer make on the wireless network using this new information?

• A. Disable 802.11 b/g data rates.
• B. Enable Band Sect in the WLC
• C. Disable RRM in the WLC.
• D. Enable rogue access point containment.

Answer: D

Explanation: Monitoring Rogue Access Point Alarms
Rogue access point radios are unauthorized access points detected by one or more Cisco lightweight access points. This page displays rogue access point alarms based on the severity you clicked in the Alarm Monitor.

NEW QUESTION 4
After implementing mesh with an IP surveillance camera connected to the LAN port on a RAP, the engineer notices that QoS is not being marked.
In this setup, what device is responsible for marking upstream traffic from the camera?

• A. IP Camera
• B. MAP
• C. RAP
• D. Wireless Controller
• E. First-Hop Router

Answer: A

NEW QUESTION 5
An engineer would like to calibrate the RF environment to improve accuracy. Which wireless attribute is added to the floor-level calculation by calibrating the floor?

• A. attenuation
• B. TX power
• C. multipath
• D. SNR

Answer: A

NEW QUESTION 6
An engineer has added an access point to a deployment after a post-installation site survey. The engineer then notices that there has been an increase in co-channel interference and retransmissions. Which two features can help mitigate the issue? (Choose two.)

• A. Coverage Hole Detection
• B. Transmit Power Control
• C. Enhanced Distributed Channel Access
• D. Cisco Compatible Extensions
• E. Dynamic Channel Assignment

Answer: CE

NEW QUESTION 7
You are designing a wireless mesh network for an oil refinery. What is the Cisco-recommended model of a Cisco Aironet 1550 Series Outdoor Access Point for this location?

• A. 1552I
• B. 1552CU
• C. 1552E
• D. 1552H

Answer: D

Explanation: Cisco Aironet 1552H Access Point
This ruggedized, outdoor, 802.11n access point is suitable for generic hazardous environments, and does not require a wireless sensor network.

NEW QUESTION 8
A customer wants to implement a wireless network in a historic location, but is concerned about the structural and aesthetic impact to the facility. Which benefit of using wireless mesh addresses these concerns?

• A. Power is required only at the installation location.
• B. The APs do not have LED lights.
• C. More wireless channels can be supported.
• D. APs do not need network connections.

Answer: D

NEW QUESTION 9
An engineer is tuning RRM parameters to improve client connectivity. Which channel band results in the best 802.11n client compatibility?

• A. UNII-2
• B. UNII-2e
• C. UNII-3
• D. UNII
• E. UNII-1

Answer: E

Explanation: 802.11 n operates on the same channel as 802.11A. For better compatibility with 802.11n clients, it is recommended to stay on lower channels (UNII-1 band).

NEW QUESTION 10
A customer wants to upgrade their current wireless infrastructure to support wireless voice capabilities. When using a voice readiness assessment tool, the customer notes that multiple areas have failed to meet the requirements.
How should the customer resolve this issue?

• A. Reduce the maximum threshold on the voice readiness tool to -67 dBm.
• B. Perform a site survey to position access points in the facility?
• C. Ensure that there is a 1 to 5 ratio of monitor mode to local mode access points
• D. Increase the power on all the access points to 25mW or more.

Answer: A
