• Question 516:

  A client on different floors in an atrium. The access points are joined to the same controller and configured in local mode. The access points are in different AP groups and have different IP addresses, but the client VLAN in the groups is the same.

  What type of roam occurs?

  A. inter-controller
  B. inter-subnet
  C. intra-VLAN
  D. intra-controller
  D. intra-controller

  ---

  Explanation

  Mobility, or roaming, is a wireless LAN client's ability to maintain its association seamlessly from one access point to another securely and with as little latency as possible. Three popular types of client roaming are:

  1. Intra-Controller Roaming: Each controller supports same-controller client roaming across access points managed by the same controller. This roaming is transparent to the client as the session is sustained, and the client continues using the same DHCP-assigned or client-assigned IP address.

  2. Inter-Controller Roaming: Multiple-controller deployments support client roaming across access points managed by controllers in the same mobility group and on the same subnet. This roaming is also transparent to the client because the session is sustained and a tunnel between controllers allows the client to continue using the same DHCP- or client-assigned IP address as long as the session remains active.

  3. Inter-Subnet Roaming: Multiple-controller deployments support client roaming across access points managed by controllers in the same mobility group on different subnets. This roaming is transparent to the client because the session is sustained and a tunnel between the controllers allows the client to continue using the same DHCP-assigned or client-assigned IP address as long as the session remains active.

• Question 517:

  Which Python code snippet must be added to the script to store the changed interface configuration to a local JSON-formatted file?

  

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

  ---

  Explanation

  1 - 'response' type is (class Response).

  2 - 'UpdateConfig' converted 'response' to a String, so it's a String.

  3 - When using write() the passed argument must be a String.

  NOT C, json.dump(ARG1, ARG2) method takes a python dictionary NOT a String, and convert it as a JSON file.

• Question 518:

  Which feature is available to clients using layer 2 roaming in a wireless infrastructure?

  A. Room to a different wireless controller that is on o different subnet and maintain the same IP address
  B. Associate to a new access point on a different wireless controller and change the IP address without connectivity interruption
  C. Associate to a new access point on the same wireless controller and change the IP address without connectivity interruption
  D. Roam to a different wireless controller that snares The same subnet and maintain the same IP address
  D. Roam to a different wireless controller that snares The same subnet and maintain the same IP address

• Question 519:

  In a Cisco SD-WAN solution, which two functions are performed by OMP? (Choose two.)

  A. advertisement of network prefixes and their attributes
  B. configuration of control and data policies
  C. gathering of underlay infrastructure data
  D. delivery of crypto keys
  E. segmentation and differentiation of traffic
  A. advertisement of network prefixes and their attributes
  D. delivery of crypto keys

  Explanation

  Service routes orginated from vEdges/vSmarts

  Reachability [vRoutes, TLOCs] Security [Encryption Keys] Service routes [Firewall/IDS] Policies throughout the fabric [Data/App-route Policies]

  https://www.grandmetric.com/knowledge-base/design_and_configure/sd-wan-overlay-management-protocol-omp/

  OMP is the control protocol that is used to exchange routing, policy, and management information between Cisco vSmart Controllers and Cisco IOS XE SD-WAN devices in the overlay network. These devices automatically initiate OMP peering sessions between themselves, and the two IP end points of the OMP session are the system IP addresses of the two devices.

  B. Each device that is looped through in the devices.txt file is put into its own dictionary that is appended to the parent list.
  C. All devices that are looped through in the devices.txt file are put into a list that is appended to the parent dictionary.
  D. All devices that are looped through in the devices.txt file are put into a single dictionary that is appended to the parent list.
  D. All devices that are looped through in the devices.txt file are put into a single dictionary that is appended to the parent list.
