Cisco Designing Cisco Enterprise Wireless Networks - 300-425 Exam Practice Test

What is the main purpose of conducting a post-deployment site survey?

An engineer needs a wireless design to provide redundancy for APs at remote sites that are connected to Cisco 3504 Wireless LAN Controllers. The central Cisco 5520 Wireless LAN Controller supports 2000 APs and has 1975 access points associated to it. The engineer decides that not all APs at the remote sites must remain functional in the event of a failure. How does the engineer ensure that the most important access points at the remote sites remain online while not impacting the main site?

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 Catalysts 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.
- Each campus acts as either secondary or tertiary backup to another
campus, with data center WLC always being the primary.
What design approach must the consulting engineer take?

A customer has a centralized wireless deployment with N+1 high availability and few open authentication SSIDs configured. After failover, all APs are broadcasting all SSIDs, but the clients are assigned IP addresses from a different subnet. The WLANs on both WLCs are configured with the same dynamic interfaces. Which feature must be incorporated in the wireless design of the second controller?

An engineer is planning a wireless deployment with two members in a mobility group. The engineer notices that there are issues establishing the mobility tunnel. The engineer must test the mobility EoIP data packet communication between two controllers. Which command runs this test?

An engineer is designing a new wireless network. The network needs to meet these requirements:
- support a high wireless client concentration
- support data over wireless
- support voice over wireless
- avoid interference
Which design approach should be taken?

An engineer must perform a Layer 2 survey for a mining facility. Which type of antenna does the engineer use in the mine shaft?

A customer has a central Cisco WLC that manages APs in FlexConnect mode. The wireless infrastructure supports multiple small branches. One branch deploys new CCX wireless phones that are authenticated by a central Cisco ISE via PEAP/IMSCHAPv2, and traffic is switched locally. The customer must reduce the number of full authentication requests and optimize roaming for the new phones. Which action accomplishes the requirement?

The wireless learn must configure a new voice SSID for optimized roaming across multiple WLCs with Cisco 8821 phones. Which two WLC settings accomplish this goal? (Choose two)

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

An engineer must perform a predictive wireless survey to indicate the number of access points required. The engineer has created a new project and imported the floor plan. Which step must be taken next for accurate AP placement?

A wireless engineer is doing a pre-site survey. Which two attributes must match between the site survey and the production clients? (Choose two.)

A customer Wi-Fi deployment is experiencing the sticky client problem and must enable the optimized roaming feature. The wireless clients have valid security credentials for an SSID and can see an AP that offers that SSID to join. What must be configured to enhance roaming?
