Question 42
What is the recommended cell overlap when designing a wireless network for Cisco Hyperlocation?
20%
30%
40%
50%
Question 43
An engineer must create data-link redundancy for the company's Cisco Wireless LAN Controller. The engineer has decided to configure LAG-based redundancy instead of port-based redundancy. Which three features of LAG-based redundancy influenced this decision? (Choose three.)
Packets are always sent out on the same port they are received on.
All interface traffic passes as long as one port is up.
The same port has multiple untagged dynamics interfaces.
Interface connection to two separate nonstacked switches is available.
Full bandwidth of all links is available.
Ports are grouped into multiple LAGs.

Question 44
An engineer is performing a predictive wireless design for a medical treatment environment, which requires data and voice services. What is the minimum requirement for the design?
overlapping -72 dBm coverage from two access points
continuous -67 dBm coverage from one access point
continuous -72 dBm coverage from one access point
overlapping -67 dBm coverage from two access points
So -67dBm covers both Data & Voice with a single AP
Question 45
A wireless engineer is designing a wireless network for a warehouse using access points with internal antennas. Which two elements have a negative effect on the wireless users? (Choose two.)
wireless channels
access point height
client authentication
client authorization
absorption

Question 46
Which statement about AP failover priority for access points when configured with priority 1 or 4 is true?
When configured with priority 1, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.
When configured with priority 4, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.
When configured with priority 4, the access point is assigned with the lowest priority level and it is marked as low. This access point fails over after other access points with the higher priority when there is primary controller failure.
When configured with priority 1, the access point is assigned with the medium priority level and it is marked as medium. This access point fails over after other access points with the higher priority when there is primary controller failure.
Question 47
An engineer must ensure that the wireless network can accomplish fast secure roaming by way of caching keys on the access points. Which key caching mechanism is enabled by default on a Cisco AireOS WLC?
SKC
OKC
802.11r
CCKM
Question 48
A technician connects a Cisco Aironet 3700 Series access point to a switch and realizes that the AP is coming up with 3x3 MIMO. Which reason explains this behavior?
A redundant power supply is unavailable on the switch.
The switch is 802.3af capable.
The AP is getting power from a power injector.
The switch is PoE+ capable.
Question 49
Which CLI command does an engineer use to validate that the redundancy peer of a Stateful Switchover pair of controllers is up and connected?
rping
ping
eping
mping
Question 50
An engineer must decide the cell overlap for a wireless voice deployment. Which Cisco measurement recommendation should be considered?
The edge of the cell should be -67 dBm.
The edge of the cell should be below 35 RSSI.
The measurement should be done on the 2.4-GHz band.
One AP should be deployed per 3000 square feet.
