Question #1

Scenario 2:

After completing the branch activation activities for all required branches, the network administrator attempts to test connectivity between the various branches and between the hubs and branches. The administrator notices a lack of connectivity despite being certain that configurations have been complete. The administrator also observed that several users are reporting intermittent connectivity to some of the applications they are accessing. Other users are reporting no access to these applications. Other users at some of the branches claim they cannot get to certain public resources. The administrator wants to ensure that all sites can talk to each other and all resources are accessible.

Exhibit.

Several reports have come in from branch locations indicating customers cannot reach applications being served by the hub location. The hub location has a single LAN-side port from which it should be learning dynamic routes for the subnets serving the applications.

How should the technician verify if the ports on the Edge are up and working?

  • A . Look under Administration and System Settings to verify if the interfaces are configured and enabled.
  • B . Look in Test&Troubleshoot under the Remote Diagnostics and run Interface status.
  • C . Look in Test&Troubleshoot under the Remote Actions and run System Health.
  • D . Look in Test&Troubleshoot under the Remote Diagnostics and run System Health.

A network administrator is trying to create multiple overlays on a single physical interface on an Edge. The administrator is able to bring up only a single overlay so far, but is having trouble with bringing up additional overlays.

What could be the possible reason?

  • A . The administrator does not have the right permission to create multiple overlays. The administrator needs to have an Operator-level privilege for this task.
  • B . On the WAN overlay configuration, verify the IP address, next-hop, and the VLAN ID configuration.
  • C . The licensing does not support multiple overlays on a single physical interface.
  • D . Multiple overlays cannot be created on a single physical interface. Multiple physical interfaces are needed.

Question #6

Scenario 2:

After completing the branch activation activities for all required branches, the network

administrator attempts to test connectivity between the various branches and between the hubs and branches. The administrator notices a lack of connectivity despite being certain that configurations have been complete. The administrator also observed that several users are reporting intermittent connectivity to some of the applications they are accessing. Other users are reporting no access to these applications. Other users at some of the branches claim they cannot get to certain public resources. The administrator wants to ensure that all sites can talk to each other and all resources are accessible.

Exhibit.

A network administrator decides to deploy a local Checkpoint VNF appliance on the Edge in London to cut back on unnecessary traffic towards the NY Hub location. While attempting to deploy the VNF, the process keeps failing.

Question #7

Scenario 3:

After resolving numerous connectivity issues throughout the various branch sites, connectivity between applications and users is finally present. The network administrator is informed that during certain tests, applications are not performing as they are expected to. Users report that call quality has not fully improved and that some of their calls either drop

or have poor voice quality where the conversation is breaking up. Other users are noticing that file transfers are slower than expect. A group of users from a few sites have reported slowness in accessing internal and external applications.

  • B . Ensure that the realtime application is matching the correct application type using the diagnostics page.
  • C . Check the status of the links using the QoE and Transport tabs for any degraded underlay issues or congestion issues.
  • D . Configure a QoS policy to load balance the realtime traffic across all links.
