Cisco Designing Cisco Wireless Networks Sample Questions:

1. A network engineer must design a new wireless solution for a company, but the budget can only stretch to include a single Cisco 9800-40 WLC. The company requires high availability between the WLC and the core switch in the event of a cable failure. The WLC must dynamically manage port redundancy and perform load balancing between APs transparently. Which design approach must the engineer take to meet the requirements?

A) Multi-LAG
B) LACP
C) LAG
D) PAgP

2. A consulting engineer is preparing to survey a brownfield deployment for a 6000-sqft building with four floors that have APs. The entire building is being remodeled and the furniture, office walls, and decoration are being updated. The engineer must perform a survey analysis on the potential RF impact of newer furniture materials. How must the survey be conducted?

A) Perform a sweep analysis first to predict the signal strength across each point in a floor.
B) Evaluate the neighbor APs strength and density based on the radio statistics information of each AP.
C) Use a survey tool with the existing AP positions using building floor maps and material configuration.
D) Measure upstream and downstream data rates based on the remodeling of the building.

3. How are mobility groups created, excluding mobility anchors?

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

4. A network engineer is designing a new wireless network for a campus. The network must include optimized performance, avoid interference, availability in high-density areas, and roaming. Which two approaches must be taken? (Choose two.)

A) 2.4 GHz frequency band with 40 MHz channels
B) 5 GHz frequency band with 40 MHz channels
C) 2.4 GHz frequency band with 20 MHz channels
D) 5 GHz frequency band with 20 MHz channels
E) 5 GHz frequency band with 80 MHz channels

5. A network engineer must review the design for a Cisco wireless deployment at a hospital. The deployment will have two Cisco 9800 WLCs configured with SSO, one Cisco 9800 WLC joined to the SSO controllers using a mobility tunnel, and one Cisco 9800 WLC that will be used as a service/dev controller and not joined using a mobility tunnel. Which high availability option must be incorporated in the design to ensure that APs choose the service/dev controller last when trying to associate?

A) secondary
B) primary
C) tertiary
D) AP failover priority
