Question 1

Scenario 1:
The Dallas Branch location is having issues getting activated. The local network administrator is aware that the Edge device received a DHCP address and was able to connect to the internet. The Orchestrator is reporting the Edge as Down. No other changes were made post activation.
A network administrator is tasked with enabling SD-WAN at three branch locations. A topology has been provided for reference. For each site, the administrator is having issues bringing edges online, as another administrator has gone ahead and created a configuration ahead of time. The organization has several branch sites. One is am Internet-only site and two are Hybrid locations with both internet and MPLS. The last location is MPLS only. There are hub data center locations in this environment as well. Please refer to the topology.
Refer to the Exhibit(s).


What is the cause of this issue?
  • Question 2

    Scenario 3:
    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.

    The network administrator determines that dynamic routes to SD-WAN sites are missing at the San Jose branch router. The network administrator decides to look into the configurations of hub Edges. All SD-WAN branch sites must use a hub to communicate with the San Jose site. Best practices have been implemented at these SD-WAN sites.
    Where should the administrator check first to verify if the configuration is correct?
  • Question 3

    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.

    A network administrator wants to achieve better high-availability and network reconvergence between LAN-side BGP Networks and the hub Edges in New York.
    What must the administrator do?
  • Question 4

    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 (hat 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.

    Which metrics can a network administrator verify in the QoE screen to determine the overall health of Underlay and Overlay?

    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 callquality 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.
    Users at multiple branches complain that a highly performant SQL Database cluster residing at the New York Data Center is not responding to database queries or inserts as expected. It is affecting the order management site. A network administrator investigates and finds that traffic from the branches are going through Seattle to reach the SQL Cluster in New York. The design for this SD-WAN network does not call for routing security.
    The SQL Cluster is reachable through either Data Center, but for performance reasons, must flow through the New York DC. The network administrator has verified that the routes are not present in the OFC and the BGP neighborship is down in Network Services.
    Refer to the Exhibit(s).

    What should the administrator verify?
