A small customer has a legacy autonomous mode Wi-Fi deployment that provides a low-density and low-capacity service. The customer wants to update and replace this deployment with the latest Wi-Fi technology but has a fixed budget that will pay only to replace the APs. Which architectural controller deployment model suits this requirement?

• A. unified
• B. cloud
• C. embedded
• D. fabric

An engineer is designing a new wireless network for an international company. The design must have these requirements:
- broadcast wireless channels based on country regulations
- controllers to support APs for regulatory domains
- RF changes applied on APs per country that are installed
- multiple-country feature to be used on the controllers
Which design approach must be taken?

• A. Create an RF group with controllers configured with the same set of countries in the random order.
• B. Install APs and controllers with the same license number across all offices globally.
• C. Create an RF group with controllers configured with the same set of countries in the same order.
• D. Install APs and controllers with the same part number across all offices globally.

A university has three campus locations and the main data center. Each campus location has a Cisco Catalyst 9800-40 WLC that manages 600 APs. The data center has a Catalyst 9800-40 WLC, which serves as an N+1 backup for each campus WLC. A consulting engineer must install four additional Catalyst 9800-40 WLCs to serve as the high availability SSO pair for each campus, but only two have been approved due to budget restrictions. The new WLCs must be implemented using these requirements:
- Data center WLC must always be available as N+1 backup to either
campus WLC.
- Campus1 WLC must operate with zero downtime.
- In the event of multiple campus outages, the AP priority order is to
support Campus3, Campus2, and then Campus1.
- No APs on campus can be left stranded without a WLC in the event of
an outage.
What design approach must the consulting engineer take?

• A. The data center WLC and Campus1 WLC are the high availability SSO pair. Campus3 APs have priority 4, Campus2 APs have priority 2, and Campus1 APs have priority 1.
• B. The Campus3 WLC is the high availability SSO pair. The data center WLC is split into two WLCs, Data Center1 and Data Center2. Campus3 APs have priority 1, Campus2 APs have priority 2, and Campus1 APs have priority 4.
• C. The Campus1 WLC is the high availability SSO pair. The data center WLC is split into two WLCs, Data Center1 and Data Center2. Campus3 APs have priority 4, Campus2 APs have priority 2, and Campus1 APs have priority 1.
• D. The data center WLC and Campus3 WLC are the high availability SSO pair. Campus1 APs have priority 4, Campus2 APs have priority 2, and Campus3 APs have priority 1.

Which statement about creating a mobility group is true, excluding mobility anchors?

• A. Each WLC must use the same mobility name and be defined as a peer in each other's static mobility members list.
• B. A mobility groups does not require all WLCs in the group to use the same virtual IP address.
• C. If WLCs with HA SSO are deployed, each WLC in the WLC HA pair considered separately as a mobility peer.
• D. The WLCs 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.

A hospital network has a Cisco WLC running version 7.5.110 code. The WLC supports thousands of handheld devices. Users of the handheld devices report battery life issues when they connect to the wireless network. An IT consulting company is hired to resolve the issue. The company suggests that the WLC be upgraded to 8.1 or later to support new IEEE 802.11-2007 amendments. Which feature increases client battery life?

• A. 802.11v
• B. 802.1x
• C. 802.11w
• D. 802.11r
