An engineer is designing a network deployment for a college with six buildings. Each building must have a WLC located in the IDF to support the APs. The wireless clients should be able to roam between the APs and the controllers. Which type of wireless architecture should be used?
- A. cloud
- B. autonomous
- C. centralized
- D. distributed
Answer : D
A wireless engineer is designing a wireless network to support real time applications over wireless. Which IEEE protocol must the engineer enable on the WLC so that neighbor list radio management packets are sent to the wireless devices?
- A. 802.11w
- B. 802.11r
- C. 802.11i
- D. 802.11k
Answer : D
An AP is receiving 802.11 packets on its 802.11a radio with an RSSI value of -77 dBm. The current AP is part of an AP group that has been assigned an RF profile with RX-SOP set to Medium for 802.11a. Which action does the AP take with the packets?
- A. All frames are classified as non-Wi-Fi frames and are not decoded by the 5 GHz radio.
- B. Frames are decoded by the 2.4 GHz radio.
- C. All frames are classified as non-Wi-Fi frames and are not decoded by the 2.4 GHz radio.
- D. Frames are decoded by the 5 GHz radio.
Answer : C

- A. 20%
- B. 30%
- C. 40%
- D. 50%
Answer : A
Refer to the exhibit. Which two statements about Cisco Prime Infrastructure are true? (Choose two.)

- B. Planning mode requires a special license in Cisco Prime Infrastructure.
- C. It shows the map editor feature in Cisco Prime Infrastructure.
- D. Controllers must be synchronized with Cisco Prime Infrastructure for planning mode to work.
- E. It shows the planning mode feature in Cisco Prime Infrastructure.
Answer : DE

- A. TSPEC
- B. RXSOP
- C. TPC
- D. LSS
- E. DFS
Answer : CE
A wireless engineer is designing a wireless network to support real time applications over wireless. Which IEEE protocol must the engineer enable on the WLC so that the number of packets that are exchanged between an access point and client are reduced and fast roaming occurs?
- A. 802.11w
- B. 802.11r
- C. 802.11i
- D. 802.11k
Answer : D
How are mobility groups created, excluding mobility anchors?
- A. Each WLC must use the same mobility domain name and be defined as a peer in each otherג€™s static mobility members list.
- B. If WLCs with HA SSO are deployed, each WLC in the WLC HA pair is considered separately as a mobility peer.
- 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. A mobility group does not require all WLCs in the group to use the same virtual IP address.
Answer : B
Which two considerations must a network engineer have when planning for voice over wireless roaming? (Choose two.)
- A. Full reauthentication introduces gaps in a voice conversation.
- B. Roaming time increases when using 802.1x + Cisco Centralized Key Management.
- C. Roaming occurs when the phone has seen at least four APs.
- D. Roaming occurs when the phone has reached גˆ’80 dBs or below.
- E. Roaming with only 802.1x authentication requires full reauthentication.
Answer : AE
What is the 9800 Series Wireless Controller mobility tunnel on a Cisco Catalyst 9800 controller?
- A. It is an IPsec tunnel with control path only.
- B. It is a CAPWAP tunnel with data path only.
- C. It is a CAPWAP tunnel with control path and data path.
- D. It is an IPsec tunnel with control path and data path.
Answer : B
An engineer must configure the virtual IP address on multiple controllers in a mobility group. Which rule must the engineer follow to ensure proper roaming?
- A. Ensure that the DNS entry is tied to the virtual IP address of the WLC.
- B. Use a unique IP address for each WLC.
- C. Ensure that the DNS Host Name field is defined.
- D. Use the same IP address for each WLC.
Answer : A
Guest anchoring is configured for a newly created SSID for a company. It has been noticed that the mobility tunnels are not up and that MPING fails from your foreign WLC to the anchor WLC. What is the reason that it is failing?
- A. A rule is needed at the firewall to allow UDP port 16666 for communication to work.
- B. A rule is needed at the firewall to allow UDP port 97 for communication to work.
- C. A rule is needed at the firewall to allow TCP port 97 for communication to work.
- D. A rule is needed at the firewall to allow TCP port 16666 for communication to work.
Answer : A
Multiple WLCs are implemented in a high-availability configuration in a mobility group. APs are deployed with only a primary controller assigned. By default, which mobility group member controller do the orphaned APs join in the event of a failed controller?

- B. controller with the lowest percent of associated APs per license capacity
- C. controller with the least CPU utilization over the last reporting period
- D. controller with the least number of associated APs
Answer : D
