  Tasks

  The operations team started configuring network devices for a new site. R10 and R20 are preconfigured with the CORP VRF. R10 has network connectivity to R20. Complete the configurations to achieve these goals:

  1. Extend the CORP VRF between R10 and R20 using Tunnel0.

  2. Protect Tunnel0 using the preconfigured profile.

  3. Configure static routing on R10 and R20 so that users in VLAN 100 and VLAN 101 that belong to the CORP VRF are able to communicate with each other. Tunnel0 should be the only interface used to route traffic for the CORP VRF

• Question 1344:

  How is a data modelling language used?

  A. To enable data to be easily structured, grouped, validated, and replicated.
  B. To represent finite and well-defined network elements that cannot be changed.
  C. To model the flows of unstructured data within the infrastructure
  D. To provide human readability to scripting languages
  A. To enable data to be easily structured, grouped, validated, and replicated.

• Question 1345:

  Refer to the exhibit.

  

  What is the result of running this code?

  A. A list of lists is created.
  B. A list of new VLANs is created.
  C. An error is displayed.
  D. A dictionary is created.
  B. A list of new VLANs is created.

  Explanation

  tried it online. the thing is that the vars are referenced and not sent by value. def main(): vlans_list = [10, 20, 30]

  add_vlans(vlans_list)

  print(vlans_list)

  def add_vlans(vlans):

  for i in range(len(vlans)):

  vlans[i]+=100

  if _name_ == '_main_':

  main()

• Question 1346:

  An engineer is connected to a Cisco router through a Telnet session.

  Which command must be issued to view the logging messages from the current session as soon as they are generated by the router?

  A. logging buffer
  B. service timestamps log uptime
  C. logging host
  D. terminal monitor
  D. terminal monitor

• Question 1347:

  Where is radio resource management performed in a Cisco SD-Access wireless solution?

  A. DNA Center
  B. control plane node
  C. wireless controller
  D. Cisco CMX
  C. wireless controller

  ---

  Explanation

  Fabric wireless controllers manage and control the fabric-mode APs using the same general model as the traditional local-mode controllers which offers the same operational advantages such as mobility control and radio resource management. A significant difference is that client traffic from wireless endpoints is not tunnelled from the APs to the wireless controller. Instead, communication from wireless clients is encapsulated in VXLAN by the fabric APs which build a tunnel to their first-hop fabric edge node. Wireless traffic it tunneled to the edge nodes as the edge nodes provide fabric services such as the Layer 3 Anycast Gateway, policy, and traffic enforcement.

• Question 1348:

  Refer to the exhibit.

  

  R4 is experiencing packet drop when trying to reach 172.16.2.7 behind R2.

  Which action resolves the issue?

  A. Insert a /24 floating static route on R2 toward R3 with metric 254.
  B. Disable auto summarization on R2.
  C. Insert a /16 floating static route on R2 toward R3 with metric 254.
  D. Enable auto summarization on all three routers R1, R2, and R3.
  B. Disable auto summarization on R2.

• Question 1349:

  What is the function of an RP in a PIM-SM network?

  A. to provide routing to the PIM leaf routers
  B. to track sources and recovers on the shared distribution tree
  C. to automate the distribution of group-to rendezvous point mappings
  D. to connect multicast sources with receivers
  B. to track sources and recovers on the shared distribution tree

• Question 1350:

  Which statement about route targets is true when using VRF-Lite?

  A. When BGP is configured, route targets are transmitted as BGP standard communities.
  B. Route targets control the import and export of routes into a customer routing table.
  C. Route targets allow customers to be assigned overlapping addresses.
  D. Route targets uniquely identify the customer routing table.
  B. Route targets control the import and export of routes into a customer routing table.

  ---

  Explanation

  Answer 'Route targets allow customers to be assigned overlapping addresses' and answer 'Route targets uniquely identify the customer routing table' are not correct as only route distinguisher (RD) identifies the customer routing table and "allows customers to be assigned overlapping addresses".

  Answer 'When BGP is configured, route targets are transmitted as BGP standard communities' is not correct as "When BGP is configured, route targets are transmitted as BGP extended communities"
