QUESTION 51

You have been contacted by a medium sized medical center to do a site survey of their existing WLAN. The current network is set up with multiple SSIDs/VLANs to separate voice and data and the networks functioning properly. The medical center would like to add Vocera voice badges to the existing VoWLAN. Which two issues need to be considered during the site survey? (Choose two.)

 

A.

The additional voice endpoints may increase additional load, which may increase delay in the WLAN and cause voice quality to degrade.

B.

There will not be any issues due to adding the Vocera voice badges because they are point-to-point devices and do not require the infrastructure to communicate.

C.

Verify the WLAN is multicast enabled for Vocera voice badges.

D.

To make these devices as efficient as possible, the Vocera voice badges should be placed on their own unicast SSID/VLAN.

E.

Verify the WLAN that is being used by the Vocera voice badges is configured in the WLC to use the Gold QoS value.

 

Correct Answer: AC

 

 

QUESTION 52

You have a client that would like to upgrade their 2.4-GHz point-to-point wireless bridge link between buildings in their facility in Mexico. Currently, they have radios from vendor A that are transmitting at 14 dBm with 6 dBm antennas. They would like to upgrade the radios to vendor B but keep the existing antennas. The new radios from vendor B have a fixed transmit power of 7 dBm. How should you proceed?

 

A.

Install the new radios with existing vendor A antennas.

B.

Install new radios with replacement vendor A antennas rated at 13 dBm.

C.

Install new radios with replacement vendor A antennas rated at 30 dBm.

D.

Install the new radios with new vendor B antennas rated at 29 dBm.

E.

Install the new radios with new vendor B antennas rated at 13 dBm.

 

Correct Answer: E
