Designing Cisco Enterprise Wireless Networks (300-425) Free Practice Test

Question 1

An engineer is working for a manufacturing company that has a centralized deployment model.
Guests at headquarters need wireless access for presentations, demonstrations, and sharing of information. The engineer must provide external users with secure guest access by connecting to anchor controllers on the DMZ. Auto-Anchor Mobility has been selected in the mobility group to accomplish it. Both anchors are configured as part of the mobility group for HQ. Which design approach ensures that clients connect to the primary controller first and are pushed to the secondary if the primary fails?

A. Configure ECMP but weigh the cost to be higher to go to the secondary.

B. Set the Anchor priority for the secondary controller to 1.

C. Configure ECMP but weigh the cost to be higher to go to the primary.

D. Set the Anchor priority for the primary controller to 1.

Question 2

A customer asks an engineer to explain the concept of mobility domains and mobility groups.
Which statement does the engineer respond with?

A. If WLCs are in the same mobility domain, they communicate with each other. Mobility groups constrain the distribution of security context of a client and also constrain AP fail-over between controllers.

B. WLCs do not need to be in the same mobility domain to communicate with each other. Mobility groups constrain the distribution of security context of a client and also constrain AP fail-over between controllers.

C. A mobility group does not constrain the distribution of security context of a client and also does not constrain AP fail-over between controllers when the WLC are in the same mobility domain.

D. If WLCs are in the same mobility domain, they communicate with each other but, if an anchor WLC is present it must be in the same mobility domain for communication to be possible.

Question 3

A wireless engineer is hired to design a network for six buildings with a WLC in each building to support the access points.
Which type of wireless architecture is being used?

A. unified deployment

B. centralized deployment

C. distributed deployment

D. autonomous deployment

Correct Answer: C

Question 4

During a client roaming event, which device is responsible for communicating the new Layer 2 EID mapping of a wireless supplicant to the fabric domain?

A. CP1

B. CP2

C. WLC

D. BN

Question 5

A customer has two Cisco wireless controllers named WLC-A and WLC-B. Each controller is in a different building on a campus. The WLCs have different Layer 3 interfaces and broadcast the same SSIDs from their respective APs. Users must remain connected to the same VLAN and maintain their IP addresses during roaming from the APs that are attached to WLC-A and WLC B.
Which action accomplishes the requirement?

A. Create an SSO cluster to ensure that client sessions sync between WLCs.

B. Create a mobility group between the two WLCs to allow auto-anchoring.

C. Enable 802.11r on each SSID on both WLCs to allow caching of the PMK.

D. Enable AP groups using the same name on both WLCs for each group.

A wireless engineer is utilizing the voice readiness tool in Cisco Prime for a customer that wants to deploy Cisco IP phones.
Which dBm range is the network inspected against?

A. -78 to -65 dBm

B. -85 to -67 dBm

C. -85 to -65 dBm

D. -72 to -67 dBm

A. Ensuring minimal RF interference

B. Using DFS channels

C. Enabling 160 MHz channels

D. Maximizing AP transmit power

Correct Answer: A

Question 8

A wireless engineer is hired to troubleshoot wireless network issues and discovers that the customer is using 802 11 ac access points with 80 MHz-wide channels in a high-density environment.
Which solution addresses these issues?

A. Disable RRM on the WLC.

B. Decrease the channel width.

C. Disable TPC on the WLC

D. Increase the minimum data rate supported

Correct Answer: B

Question 9

What is the minimum recommended RSSI for designing a WLAN to support data applications?

A. ?0 dBm

B. ?0 dBm

C. ?7 dBm

D. ?5 dBm

Correct Answer: B

Question 10

An engineer has been tasked with optimizing roaming for all the wireless networks used by shops located in a shopping center. A unique WLAN is assigned to each individual shop named ret470632970B55XX, where the last two digits indicate the shop's location. The wireless network consists of 9800 controllers and Cisco 9100 APs. What should the engineer configure on the controllers to optimize roaming?

A. create an interface per shop

B. assign access rules based on location

C. disable the 802.11a/b network

D. enable AES encryption

Correct Answer: A

Question 11

A university lecture hall has a Cisco wireless high-density network with this configuration:
- 5 GHz only
- 20-MHz channels
- UNII-1, UNII-2, and UNII2-E channels
- TPC minimum = 8
- TPC maximum = 14
The lecture hall is 200 feet by 100 feet and has 16 Cisco APs that use directional antennas.
Which feature must be included in the design to mitigate and reduce high-channel utilization from rogue APs?

A. 802.11w

B. DFS detection

C. RxSOP

D. band select

Question 12

A customer has a single anchor WLC named Anchor A. Anchor A is in a DMZ and provides guest access.
