• Question 242:

  Your customer is thinking of migrating the exiting IEEE 802.11b/g network to an IEEE 802.11ac network which two statement are true ?(choose two)

  A. Backward compatibility need to be considered for the existing legacy IEEE 802.11b/g mobile devices.
  B. Channel option are limited on the radio band UNII 3 due to DFS
  C. Ensure that the WLANs have WMM enabled and support open or WPA2/AES encryption 1n order to reach IEEE 802.11ac speeds even on IEEE. 802.11ac clients
  D. Fewer APs have to be proposed because the IEEE 802.llac network provides a faster speed and larger converge area compared with the IEEE 802.11b/g network.
  A. Backward compatibility need to be considered for the existing legacy IEEE 802.11b/g mobile devices.
  C. Ensure that the WLANs have WMM enabled and support open or WPA2/AES encryption 1n order to reach IEEE 802.11ac speeds even on IEEE. 802.11ac clients

• Question 243:

  Which statement about a Cisco Mesh Network when a radar event is detected by the MAP on a mesh tree when coordinated channel change is enabled Is true?

  A. The MAP immediately stops transmission of the current channel and joins the parent again after 30 minutes after the channel is marked as clean.
  B. The MAP continues transmission of the beacons and probes for 10 seconds after the radar detection and suspends operation for the next 30 mins.
  C. The MAP propagates radar event information to the RAP in the same BGN. Searchs for a different parent working on a nono-dfs channel and join there.
  D. The MAP propagates the radar event information to the RAP and the whole sector moves to the new channel.
  B. The MAP continues transmission of the beacons and probes for 10 seconds after the radar detection and suspends operation for the next 30 mins.

• Question 244:

  A corporation has a Cisco 5520 WLC running software 8.x. configured with US country code. They have recently purchased 20 AIR-AP3702I-UXK9 APs to replace older APs in one of their branch offices. After those are deployed, users report

  that they can no longer access SSIDs that are operating on the 5 GHz band.

  Which cause of this problem is true?

  A. The 5 GHz radio operates in scanner mode until the APs are primed.
  B. The network administrator mist disable the 5 GHz radio interfaces and re-enable them on every UX AP to make the 5 GHz radios operational on all UX APs.
  C. The 5 GHz radio operates in rogue detection mode and cannot be changed to any other station role until the APs are primed.
  D. The 5 GHz radio is in down state until the APs are primed.
  A. The 5 GHz radio operates in scanner mode until the APs are primed.

• Question 245:

  Which two statements about AP Local Authentication by FlexConnect AP in standalone mode are true? (Choose two)

  A. From AireOS release 8.0, Cisco Extended Keying Groups (CEKG) is a supported Local Authentication Protocol when deploying FlexConnect.
  B. Only LEAP, EAP-FAST, PEAP, and EAP-TLS authentications are supported.
  C. Cisco Wireless LAN Controller must generate a certificate signing request by itself for submitting to a certificate authority for signing.
  D. Only the vendor Certificate Authority (CA) certificate has to be downloaded to the Cisco Wireless LAN Controller for EAP-TLS authentication.
  E. When using EAP-TLS, a FlexConnect Group must be created so that the Cisco Wireless LAN Controller can push the certificates to the FlexConnect AP in the FlexConnect Group.
  B. Only LEAP, EAP-FAST, PEAP, and EAP-TLS authentications are supported.
  E. When using EAP-TLS, a FlexConnect Group must be created so that the Cisco Wireless LAN Controller can push the certificates to the FlexConnect AP in the FlexConnect Group.

• Question 246:

  Which statement about network automation and/or network orchestration is true?

  A. Automation focuses on coordinating multiple tasks at the same time.
  B. Orchestration and automation focus on a single task at a time.
  C. Orchestration focuses on coordinating multiple tasks at the same time.
  D. Automation and orchestration focus on coordinating multiple tasks at the same time.
  C. Orchestration focuses on coordinating multiple tasks at the same time.

  C. The AP exceeds the number of joined APs permitted by the controller license.
  D. The date and time on the Cisco WLC and AP do not match.
  E. The AP does not have a valid certificate.
  F. The Cisco WLC does not have a valid image for this AP model.
  G. The AP MAC address has not been added into the MAC filter list of the controller.
  G. The AP MAC address has not been added into the MAC filter list of the controller.
