VMware SD-WAN Troubleshoot Exam
Last exam update: Nov 14 ,2024
Question 1
Scenario 1:
A network administrator is tasked with enabling SO-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 an 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.
After the network administrator has determined the problem with the Edge not being able to access
the Internet, the administrator receives another error stating that the SD-WAN Orchestrator is still
not reachable.
The VCO's address is Amer-vcoOl.velocloud.net.
Refer to the Exhibit(s).
What might be disallowing the Edge to communicate with the Orchestrator?
- A. The SD-WAN Orchestrator specified is incorrect, and a new activation email needs to be sent.
- B. The local firewall that the Edge uses to reach externally is blocking UDP Port 53 in both directions.
- C. The SD-WAN Orchestrator has a limited 60-second window for the Edge to come online.
- D. The SD-WAN Orchestrator is not being resolved for DNS.
Answer:
C
Question 2
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 is investigating connectivity issues between Chicago and San Jose. The
administrator browses to the Overlay Flow Control (OFC) window and notices that the screen is blank
with no routes shown in the OFC.

- B. There is an invalid MTU configuration at Chicago.
- C. OSPF or BGP is not enabled.
- D. The routing table on the Edges has not been initialized.
Answer:

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 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.
Exhibit.
