- Question 1Beginner
FlexConnect · Implement Office Extend
When deploying Cisco OfficeExtend Access Points (OEAP) for remote teleworkers, which protocol is utilized to securely encrypt both the control and data planes between the remote AP and the corporate Catalyst 9800 WLC over the public internet?
Show answer & explanation
Correct answer: B
Cisco OfficeExtend Access Points (OEAPs) use Datagram Transport Layer Security (DTLS) to encrypt both the CAPWAP control and data tunnels over the public internet. This ensures that corporate data remains secure without requiring the end user to initiate a separate software VPN connection.
- Question 2Beginner
FlexConnect · FlexConnect groups and roaming
True or False: To successfully achieve 802.11r Fast Transition (FT) roaming between two FlexConnect APs that are utilizing local switching and local authentication, both APs must be assigned to the exact same FlexConnect group.
Show answer & explanation
Correct answer: A
True. For fast roaming protocols (such as 802.11r, CCKM, or OKC) to work properly in a FlexConnect deployment with local switching, the APs must be part of the same FlexConnect group. This allows the APs to share client PMK (Pairwise Master Key) cache information with each other.
- Question 3Intermediate
FlexConnect · Split tunneling and fault tolerance
During a WAN failure, a FlexConnect AP loses its CAPWAP tunnel to the Catalyst 9800 WLC and transitions into Standalone mode. What happens to existing wireless clients that are connected to a locally switched, WPA2-PSK WLAN on this AP?
Show answer & explanation
Correct answer: B
When a FlexConnect AP enters Standalone mode due to a WLC reachability failure, existing clients on locally switched WLANs remain connected and can continue passing local traffic. New clients can also authenticate and associate if the WLAN is configured for local authentication (which WPA2-PSK natively supports locally).
- Question 4Intermediate
QoS on a Wireless Network · Implement QoS schemes based on requirements including wired to wireless mapping
When implementing wired-to-wireless QoS mapping on a Cisco wireless network, voice traffic marked with DSCP EF (Expedited Forwarding, decimal 46) on the wired network will be mapped to 802.11 User Priority (UP) value: ____.
Show answer & explanation
Correct answer: C
By standard Cisco and IEEE 802.11 QoS mapping conventions, DSCP EF (46) is designated for Voice traffic and maps directly to 802.11 User Priority (UP) 6, which falls into the Voice Access Category (AC_VO).
- Question 5Advanced
QoS on a Wireless Network · Implement AVC
A wireless engineer is tasked with configuring Application Visibility and Control (AVC) on a Catalyst 9800 WLC to explicitly drop all Netflix video streaming traffic on the Corporate WLAN, while allowing all other standard HTTPS browsing.
After creating the AVC profile with the 'mark drop' action for the Netflix application, what is the correct next step to apply this configuration?
Show answer & explanation
Correct answer: B
On the Catalyst 9800 (IOS-XE architecture), features related to client policies, including QoS, AVC, and VLAN assignments, are applied within the Policy Profile. The Policy Profile is then bound to a WLAN Profile via a Policy Tag. Applying AVC directly to the WLAN is the older AireOS method.
- Question 6Beginner
QoS on a Wireless Network · Implement QoS for wireless clients
An administrator notices that wireless clients on a newly deployed WPA2-PSK SSID are unable to connect at 802.11ac or 802.11ax data rates, and are instead capped at a maximum of 54 Mbps (802.11a/g rates). What QoS misconfiguration is the most likely cause of this issue?
Show answer & explanation
Correct answer: B
The Wi-Fi Alliance mandates that Wi-Fi Multimedia (WMM) must be enabled (Allowed or Required) for clients to achieve High Throughput (802.11n), Very High Throughput (802.11ac), or High Efficiency (802.11ax) data rates. If WMM is disabled, clients will fall back to legacy 802.11a/b/g data rates (maximum 54 Mbps).
