113. Frage
What defines device sensitivity in a wireless environment?
Antwort: B
Begründung:
Device sensitivity in a wireless environment refers to receiver sensitivity: the minimum RF signal level a client or AP radio must receive to successfully detect, demodulate, and decode a transmission. Cisco defines receiver sensitivity as the minimum signal power level, expressed in dBm or mW, required for a receiver to accurately decode a given signal. Cisco RF design guidance further states that sensitivity indicates the lowest received power before the receiver considers the signal unintelligible.
Therefore, option A is correct because sensitivity is fundamentally about the radio's capability to process a received signal at low power levels. A more sensitive receiver can decode weaker frames, improving effective coverage and receive performance, provided the signal-to-noise ratio and interference conditions remain acceptable. Cisco also notes that individual device sensitivity determines how well a device can hear and demodulate RF energy, which directly affects contention behavior and WLAN performance in dense environments. Redundant gateways, beacon interval synchronization, and key refresh schedules are Layer 3 availability, 802.11 timing, and security-key management topics; they do not define RF receiver sensitivity.
114. Frage
Refer to the exhibit. A retail business is deploying guest wireless across its remote branch locations. Each branch uses FlexConnect APs in local switching mode, and the central wireless LAN controller is configured with an ACL named CWA_REDIRECT. Cisco ISE is configured to return this ACL during the authentication process for central web authentication (CWA). However, when clients attempt to connect to the guest wireless LAN, they are added to the exclusion list.
Which configuration step resolves the connectivity issue?
Antwort: D
Begründung:
The failure is caused by the redirect ACL not being available where enforcement occurs. In FlexConnect local switching, client data-plane handling occurs on the AP, so the CWA redirect ACL cannot exist only as a controller ACL or only as a policy-profile reference. Cisco states that the redirect ACL is a punt ACL and that, for FlexConnect local switching, the ACL must be predefined on the AP because the AAA server returns only the ACL name, not the ACL definition.
The exhibit shows Redirect ACL failure and EXCLUDE_PUNT_ACL_FAIL, which aligns with an AP-side punt/redirect ACL application failure. Cisco's Catalyst 9800 CWA configuration specifically requires the redirect ACL definition to be sent through the FlexConnect profile; in the GUI this is done under the Flex Profile Policy ACL tab by adding the ACL, enabling central web authentication, and applying the change. The equivalent CLI is wireless profile flex <profile> followed by acl-policy <acl-name> and central-webauth, after which the AP uses the ACL for client redirection. AP-Join profiles do not carry client redirect ACL policy, and adding the ACL only to the policy profile does not push it to FlexConnect APs for local switching.
115. Frage
Refer to the exhibit. A wireless controller is deployed at a branch location to facilitate secure client connectivity. A network engineer configures a WLAN using 802.1X to align with company security policies. Which configuration enables client authentication for this WLAN?
Antwort: C
Begründung:
The command that enables 802.1X client authentication for this WLAN is security dot1x authentication-list ISE_GROUP. On a Cisco Catalyst 9800 WLC, the WLAN configuration defines Layer 2 security behavior, including whether the SSID uses 802.1X and which AAA method list is used for EAP/RADIUS authentication. Cisco documents the CLI workflow for 802.1X WLAN authentication as entering WLAN configuration mode and applying security dot1x authentication- list <authenticate-list-name>, explicitly describing this as the step to enable the authentication list for 802.1X security. Cisco's Catalyst 9800 configuration example also shows the exact form security dot1x authentication- list ISE_GROUP and states that the WLAN is then configured with
802.1X authentication.
no ip mac-binding disables IP-to-MAC binding checks and does not select a RADIUS method list.
aaa override enable allows authorization attributes from AAA/ISE to be applied after authentication, but it does not initiate 802.1X authentication. wlan branch1 policy branch1_policy maps the WLAN to a policy profile through a policy tag, but it is not the authentication command.
116. Frage
Which solution enables a seamless user experience when roaming in a wireless network?
Antwort: C
Begründung:
Fast transition is the correct solution because it refers to IEEE 802.11r Fast BSS Transition, which reduces the authentication delay when a wireless client roams from one AP to another. Cisco describes 802.11r Fast Transition as a feature for seamless wireless roaming and states that, after configuration, the WLAN supports faster client roaming between access points. Cisco's Catalyst 9800 roaming documentation also identifies
802.11r as the mechanism focused on seamless transition between APs, while 802.11k and 802.11v assist with neighbor reporting and network-assisted roaming decisions.
The core advantage is that key negotiation and authentication preparation occur before or during the roam, reducing the interruption experienced by latency-sensitive applications such as voice, video, collaboration tools, and real-time enterprise applications. Static VLAN policy only controls segmentation and does not accelerate roaming. Optimized roaming can help discourage sticky clients from remaining associated to poor- quality APs, but it is not the primary fast-roam authentication mechanism. A redundant RF profile is not an
802.11 roaming solution. Reference topics:802.11r Fast BSS Transition, client roaming, WLAN mobility behavior, Catalyst 9800 WLAN security, and seamless roaming design.
117. Frage
A university is deploying Cisco Catalyst 9176 APs at several satellite campuses, each with its own subnet and DNS services. The APs will be shipped with only their MAC addresses preregistered on the WLC. The satellite campuses do not use DHCP option 43, but they have access to a central DNS server. IT staff want APs to discover and join the Catalyst 9800 WLC automatically without site visits. Which solution must the IT staff implement?
Antwort: B
Begründung:
For Cisco Catalyst 9176 APs deployed at remote sites without DHCP option 43, automatic WLC discovery can be accomplished using DNS-based CAPWAP controller discovery. By creating a DNS A record named cisco-capwap-controller.<domain> that resolves to the WLC management IP address, APs can query DNS and locate their centralized controller automatically, eliminating the need for site visits or manual configuration. This method is preferred for large-scale or satellite deployments where APs may exist on different subnets and traditional DHCP-based discovery is unavailable.
