1. Question 121 · 294 in bank

   An engineer is configuring a wireless LAN controller and is setting these 802.11a/n data rates: • 5.5 Mbps - Supported • 11 Mbps - Mandatory • 24 Mbps - Disabled • 56 Mpbs - Supported Which configuration change must be made for the multicast broadcast to be sent over 24 Mbps?

   • ASet the 24 Mpbs rates to Supported.
   • BSet the 56 Mpbs rates to Disable.
   • CSet the 24 Mpbs rates to Mandatory.
   • DSet all rates to Disable except 11 Mpbs rates.

   Show answer

   Answer: A

   Explanation

   Option C suggests setting the 24 Mbps rates to Mandatory. However, setting the 24 Mbps rates to Mandatory would require all clients to support and use 24 Mbps for data transmission, which might not be feasible or desirable in all situations. In a typical scenario, it's more common to set data rates as Supported rather than Mandatory. This gives the network more flexibility and allows clients to use the best available data rate based on their capabilities and the conditions of the wireless environment. Therefore, setting the 24 Mbps rates to Supported would allow multicast broadcast to be sent over 24 Mbps without forcing all clients to use it exclusively, making it a more practical choice.

3. Question 123 · 294 in bank

   A network engineer wants to implement QoS across the network that supports multiple VLANs. All the APs are connected to switch ports and are configured in local mode. Which trust model must be configured on the switch ports to which the APs are connected?

   • ACoS
   • BWMM UP
   • CDSCP
   • DIPP

   Show answer

   Answer: C

   Explanation

   provided answer is correct. Switchports connected to local mode access points (APs) and Hybrid Remote Edge Access Point (H-REAP)/FlexConnect APs with no locally switching Wireless LANs (WLANs) should be access ports set with the mls qos trust dscp command. It could not be B as there is no such thing. 3 options for WMM are disabled, required, and allowed.

5. Question 125 · 294 in bank

   An engineer must send Cisco OEAPs to the homes of employees. The APs must be able to discover and join the WLC when they connect to each employee home network. Which action accomplishes this task?

   • AUse the WLC name and management IP address to configure the OEAPs.
   • BUse the OEAP management IP address to listen for discovery broadcasts from the WLC.
   • CUse the WLC name and management IP address to configure the DNS server.
   • DUse DHCP Option 43 to configure the WLAN name and management IP address.

   Show answer

   Answer: A

   Explanation

   Configure one or more controllers for the access point as follows: Click the High Availability tab. Enter the name and IP address of the primary controller for this access point in the Primary Controller Name and Management IP Address text boxes.

   Refer to the exhibit. An engineer implemented a CPU ACL on the controller, and now the Web Authentication Redirect page is not working. What must be changed for the redirect page to work?

   • AThe permit statement must be directed to the controller management address.
   • BThe permit statement for 192.0.2.100 must be in both directions.
   • CThe Web Authentication Redirect must be configured on the CPU ACLs.
   • DThe Web Authentication Redirect must be HTTP.

   Show answer

   Answer: B

   Explanation

   answer is B as per the below - Therefore, if CPU ACLs are enabled in the WLC, an allow rule for the virtual interface IP is required (In ANY direction) in these conditions: - When the CPU ACL does not have an allow ALL rule for both directions. - When there exists an allow ALL rule, but there also exists a DENY rule for port 443 or 80 of higher precedence. https://www.cisco.com/c/en/us/support/docs/wireless/5500-series-wireless-controllers/108501-webauth-tshoot.html
