• Question 184:

  When a Flex Connect AP is in the "local authentication, local switching" state, it handles client authentication and switches client data packets locally. This state is valid in standalone mode and connected mode. Which three statements about a FlexConnect AP are true? (Choose three).

  A. In connected mode, the AP provides minimal information about the locally authenticated client to the controller. This information is not available on the controller policy type. Access VLAN. VLAN name, supported rates. Encryption ciphter.
  B. In connected mode, the access point provides minimal information about the locally authenticated client to the controller. However, this information is available to the controller policy type., access VLAN, VLAN name, supported rates, encryption cipher.
  C. Local authentication is useful where you cannot maintain a remote office setup of a minimum bandwidth of 128 kbps with the round-trip latency no greater than 100 ms and the maximum transmission unit no smaller than 576 bytes.
  D. Local authentication is useful where you cannot maintain a remote office setup of a minimum bandwidth of 128 kbps with the round-trip latency no greater than 150 ms and the maximum transmission unit no higher than 500 bytes.
  E. Local authentication in connected mode does not require any WLAN configuration.
  F. Local authentication can be enabled only on the WLAN of a FlexConnect AP that is in local switching mode.
  A. In connected mode, the AP provides minimal information about the locally authenticated client to the controller. This information is not available on the controller policy type. Access VLAN. VLAN name, supported rates. Encryption ciphter.
  C. Local authentication is useful where you cannot maintain a remote office setup of a minimum bandwidth of 128 kbps with the round-trip latency no greater than 100 ms and the maximum transmission unit no smaller than 576 bytes.
  F. Local authentication can be enabled only on the WLAN of a FlexConnect AP that is in local switching mode.

• Question 185:

  Which description is correct with regard to the operation of an access point in Rogue Location discovery Protocol Mode?

  A. The AP uses the existing wireless infrastructure in order to scan for rogue AP's. Once discovered, these rogues are added to a local list that includes the rogue's BSSIDs, MAC addresses and any discovered security provisions (WPA, WEP etc)
  B. The AP moves to the rogue channel and attempts to connect to the rogue as a client. The AP then tries to obtain an IP address and forwards a UDP packet to the controller through the rogue. If the controller receives this packet, the network administrator is notified that a rogue AP has been discovered on the wired network
  C. The AP detects a rogue client and then the network administrator is able to contain both the rogue AP and the rogue clients. This can be achieved because 802.11 deauthentication packets are sent to clients that are associated to rogue APs so threats such as holes are mitigated
  D. The AP determines whether or not a rogue access point is on a trusted network. It does not provide RF service of any kind but rather receives periodic rogue access point reports from the controller and sniffs all ARP packets. If it finds a match between an ARP request and a MAC address it receives from the controller. It generates a rogue access point alert to the controller
  B. The AP moves to the rogue channel and attempts to connect to the rogue as a client. The AP then tries to obtain an IP address and forwards a UDP packet to the controller through the rogue. If the controller receives this packet, the network administrator is notified that a rogue AP has been discovered on the wired network

• Question 187:

  When connecting an autonomous access point in workgroup bridge mode to a WLAN configured on a Cisco WLC. Which two options are true? (Choose two.)

  A. The WGB mode allows to connect only one wired client behind the WGB to the WLAN.
  B. The WGB cannot serve wireless clients.
  C. The traffic of the wired client behind the WGB can be tunneled only to the Cisco WLC on the VLAN configured for the dynamic interface of the WLAN.
  D. The traffic of the wired client tagged on a specific VLAN behind the WGB can be tunneled to the same VLAN behind the the Cisco WLC.
  E. The WGB creates a network extension for the wired clients.
  F. The WGB could serve wireless clients only on the other radio not connecting to the WLAN.
  B. The WGB cannot serve wireless clients.
  C. The traffic of the wired client behind the WGB can be tunneled only to the Cisco WLC on the VLAN configured for the dynamic interface of the WLAN.

• Question 188:

  Refer to the exhibit. You enabled NAT to make sure that your WLC is publicly reachable. If other NAT parameters are left to default, which statement is true?

  

  A. The AP WLC discovery fails for APs in local mode using 209.165.200.44
  B. The AP WLC discovery succeeds for OEAPs joining the WLC using 192.168.3.44.
  C. The AP WLC discovery fails for APs in local mode using 192.168.3.44.
  D. The AP WLC discovery succeeds for OEAPs joining the WLC using 192.168.3.44 or 209.165.200.44.
  A. The AP WLC discovery fails for APs in local mode using 209.165.200.44
