Which two metrics does the engineer verify to ensure that the wireless network can support voice services? (Choose two.)
- A . The coverage area must have a noise floor that does not exceed -87 dBm.
- B . The client device must have at least an -67 dBm RSSI.
- C . The rate of retransmitted packets must be 15 percent or below.
- D . The rate of retransmitted packets must be 20 percent or below.
- E . The client device must have at least an -65 dBm RSSI.
Which three pieces of equipment are needed to conduct a fully measured wireless survey? (Choose three.)
- A . PoE battery
- B . spirit level
- C . access point
- D . tall tripod
- E . goggles
- F . ladder
A company has 10 access point licenses available on their backup Cisco WLC and their primary Cisco WLC is at full capacity, 5 access points are set to high failover priority and 7 access points are set to critical failover priority. During a failure, not all critical access points failed over to the backup Cisco WLC.
Which configuration is the cause of this issue?
- A . The high priority access point is oversubscribed.
- B . network ap-priority is set to enable.
- C . The critical priority access point count is oversubscribed.
- D . network ap-priority is set to disable.
Which CLI command does an engineer use to validate that the redundancy peer of a Stateful Switchover pair of controllers is up and connected?
- A . rping
- B . ping
- C . eping
- D . mping
An engineer must decide the cell overlap for a wireless voice deployment.
Which Cisco measurement recommendation should be considered?
- A . The edge of the cell should be -67 dBm.
- B . The edge of the cell should be below 35 RSSI.
- C . The measurement should be done on the 2.4-GHz band.
- D . One AP should be deployed per 3000 square feet.
A network engineer is configuring high availability on an access point.
What is the maximum number of controllers that can be configured?
- A . 1
- B . 2
- C . 3
- D . 4
An engineer must configure the virtual IP address on multiple controllers in a mobility group.
Which rule must the engineer follows to ensure proper roaming?
- A . Ensure that the DNS entry is tied to the virtual IP address of the WLC.
- B . Use a unique IP address for each WLC.
- C . Ensure that the DNS Host Name field is defined.
- D . Use the same IP address for each WLC.
A wireless engineer is utilizing the voice readiness tool in Cisco Prime for a customer that wants to deploy Cisco IP phones.
Which dBm range is the network inspected against?
- A . -78 to -65 dBm
- B . -72 to -67 dBm
- C . -85 to -65 dBm
- D . -85 to -67 dBm
An engineer is reducing the subnet size of the corporate WLAN by segmenting the VLAN into smaller subnets. Clients will be assigned a subnet by location.
Which type of groups can the engineer use to map the smaller subnets to the corporate WLAN?
- A . WLC port groups
- B . RF groups
- C . AP groups
- D . interface groups
