VMware SD-WAN Troubleshoot Exam
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.
Users at the London site are complaining of various intermittent issues around websites not loading,
or applications being remotely accessed disconnecting sporadically and reconnecting after a few
minutes. The network administrator does not see anything strange on the Edge overview page and
decides to check if the CPU or memory have been hitting close to 100/o.
Where should the administrator verify this information?
- A. In the VCO > Test 8c Troubleshoot > Remote Diagnostics > System Status
- B. In the VCO > Monitor > Click London_Site01 > Click the System Tab
- C. In the VCO > Remote Troubleshooting > Remote Actions > System Status

Question 7
Scenario 2:
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.
A network administrator has configured a Business Policy to send a specific application directly out
an underlay interface. Users have complained of slow responses for that application. While
troubleshooting, the network administrator finds the traffic is actually taking an overlay path to
another SD-WAN Edge.
What is causing this behavior?
- A. The other Edge location is advertising a secure route for the application's subnet.
- B. uI has been configured forcing traffic into the underlay towards the hub.
- C. Configuring Business Policy Direct settings have no affect on traffic flows.
- D. Internet Backha.
- E. The underlay path is not available forcing traffic into the overlay.
Answer:
E
Question 8
Scenario 1:
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 lime. 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.
Exhibit.
When attempting to activate an Edge, after clicking on the "activation link" in the email that was sent
to the network administrator, the Edge's local UI shows as "Internet down". This is preventing the
Edge from coming online and being activated. When referring to the output, the network
administrator notices that the Edge has received DHCP addressing.
What could be preventing the Edge from coming online?
- A. The next hop does not respond to ICMP pings.
- B. Cloud VPN is not enabled in the AMER Branch profile.
- C. The subnet mask assigned to the Edge is incorrect.
- D. The Edge's profile does not specify the correct Edge Model.
Answer:
A
Question 9
Scenario 2:

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 SD-WAN Edge at this location has been activated. It is incapable of establishing any overlay
tunnels. Due to this being an internet only branch, no underlay connectivity is present to the hubs.
The SD-WAN Edge is connected behind a firewall and the security team states that all necessary ports
are open.
How can this issue be resolved?
- A. The security team needs to open TCP port 4500 instead of TCP port 2426.
- B. The security team need to open TCP port 2426 outbound but not inbound.
- C. The security team needs to open TCP port 22 instead of TCP port 2426.
- D. The security team needs to open UDP port 2426 outbound and inbound.

accessible.
Exhibit.
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?

- 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.

A
Question 11
Scenario 1:

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?
