Questions # 81:

Clustering Cisco WLCs into a single RF group enables the RRM algorithms to scale beyond the capabilities of a single Cisco WLC. How many WLC and APs in an RF group can the controller software scale up to in WLC release 8.9 depending on the platform?

Options:

A.

up to 20 WLCs and 1000 APs

B.

up to 20 WLCs and 3000 APs

C.

up to 20 WLCs and 4000 APs

D.

up to 20 WLCs and 6000 APs

Questions # 82:

An engineer is performing an active survey of a network that must support different types of mobile devices. The devices must be able to run an application that requires a minimum RF of 73 dBm. Which mobile device must be used for the survey?

Options:

A.

one that has a receiver sensitivity of -70 dBm

B.

one that has the lowest receiver sensitivity

C.

one that has the most updated wireless card

D.

one that has 802.11a wireless support

Questions # 83:

How are mobility groups created, excluding mobility anchors?

Options:

A.

The WLGs do not have to be of the same model or type to be a member of a mobility group, however each member should be running different software versions.

B.

A mobility group does not require ell WLCs in the group lo use the same virtual IP address.

C.

Each WLC must use the same mobility domain name and be defined as a peer in each other' s static mobility members list.

D.

If WLCs with HA SSO are deployed, each WLC in the WLC HA pair is considered separately as a mobility peer.

Questions # 84:

Which authentication method is most scalable for enterprise WLAN deployments?

Options:

A.

WPA2-PSK

B.

MAC filtering

C.

WPA3-SAE

D.

802.1X with RADIUS

Questions # 85:

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?

Options:

A.

A redundant power supply is unavailable on the switch.

B.

The switch is 802.3af capable.

C.

The AP is getting power from a power injector.

D.

The switch is PoE+ capable.

Questions # 86:

How does AP failover priority for access points function when configured with priority 1 or 4?

Options:

A.

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.

B.

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.

C.

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.

D.

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.

Questions # 87:

A hospital wireless environment was designed with these characteristics:

• RF coverage

• better than -67 dBm in the 5 GHz spectrum

• RRM be used for DCA and TPC in the 2.4 GHz band

• RRM be used for DCA and TPC in the 5 GHz band

After deployment, why do many of the legacy 802.11b/g devices have difficulty maintaining connectivity?

Options:

A.

Excessive co-channel interference in the 2.4 GHz band exists.

B.

Excessive overlapping channels in the 2.4 GHz band exists.

C.

TPC drastically increases Tx power in the 2.4 GHz band.

D.

TPC drastically reduces Tx power in the 2.4 GHz band.

Questions # 88:

A hospital has a Cisco Catalyst 9800 Series Wireless Controller in a SSO solution deployed to the primary data center The hospital plans to increase redundancy in the wireless environment Management decides to deploy an extra Catalyst 9800 WLC offsite to another data center on a different subnet. A WAN link connects the data centers with a firewall at both ends. Which two design approaches must the engineer take to ensure that the APs can fail over? (Choose two)

Options:

A.

Create a mobility tunnel between the wireless controllers.

B.

Open HTTPS port 443 between the wireless controllers.

C.

Create a static RF group leader on one of the wireless controllers.

D.

Open UDP ports 16666 and 16667 between the wireless controllers.

E.

Create a mobility group with the same names on both wireless controllers.

Questions # 89:

An engineer is designing a wireless network for a small airport and completes the initial walkthrough phase of the facility Which step of the WLAN site survey should the engineer perform next?

Options:

A.

predeployment survey

B.

active survey

C.

post-deployment survey

D.

passive survey

Questions # 90:

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?

Options:

A.

SKC

B.

OKC

C.

802.11r

D.

CCKM
