• Question 156:

  Which website allows access to visualize the geography screen from vManager using the internet?

  A. *.globalstreetmaps.org
  B. *.fullstreetmaps.org
  C. *.callstreetmaps.org
  D. *.openstreetmaps.org

  How must the data policy be configured to establish communication between the sites and server to avoid overlapping?

  

  

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

• Question 158:

  Which multicast component is irrelevant when defining a multicast replicator outside the local network without any multicast sources or receivers?

  A. overlay BFD
  B. PIM interfaces
  C. OMP
  D. TLOC
  B. PIM interfaces

  ---

  Explanation

  When defining a multicast replicator outside the local network without any multicast sources or receivers, the PIM interfaces (B) are irrelevant. PIM (Protocol Independent Multicast) interfaces are used to establish multicast routing within a network, specifically for managing multicast traffic within the local network.

  In the absence of multicast sources and receivers within the local network, PIM interfaces serve no purpose, as there is no multicast traffic to route or manage. The focus in this scenario would be on the configuration of multicast replication and routing outside the local network, as indicated by the mention of defining a multicast replicator.

• Question 159:

  Which two REST API functions are performed for Cisco devices in an overlay network? (Choose two)

  A. distributing a Snort image among devices
  B. attaching a device configuration template
  C. managing connections for smart licensing
  D. monitoring device certificates
  E. querying a device and aggregating statistics
  B. attaching a device configuration template
  D. monitoring device certificates

• Question 160:

  How many vManage NMSs should be installed in each domain to achieve scalability and redundancy?

  A. two clusters
  B. two instances
  C. two or more in a cluster
  D. three or more in a cluster
  D. three or more in a cluster

  ---

  Explanation

  A highly available Cisco SD-WAN network contains three or more vManage NMSs in each domain. This scenario is referred to as a cluster of vManage NMSs, and each vManage NMS in a cluster is referred to as a vManage instance. Each vManage instance or device in a cluster can manage approximately 2000 devices, so a cluster of three vManage devices can manage up to 6000 devices. The vManage devices automatically load-balances the devices that they manage.

  With three devices, the vManage cluster remains operational if one of the devices in that cluster fail.
