VMware SD-WAN Troubleshoot Questions and Answers

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.

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?

Options:

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.

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?

Options:

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 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.

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).

Exhibit.

What should the administrator verify?

Options:

A.

The BGP configuration has a filter in place to deny the prefix in New York.

B.

The BGP Authentication matches on both sides.

C.

The BGP configuration has a filter in place to deny the prefix in Seattle.

D.

Backhauling through the Seattle DC is disabled.

Question 4

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 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.

Exhibit.

The network administrator determines the issue preventing the Dallas Branch from coming online.

Refer to the Exhibit(s).

What must the administrator do for the Edge to communicate with the Orchestrator and other branches?

Options:

A.

Reverse the WAN Overlay configurations

B.

Update the Orchestrator to the latest version as it enables "Auto WAN Swapping"

C.

Delete the User Defined WAN Overlays as the Orchestrator will discover these automatically on MPLS and Internet

D.

Create a User-defined WAN Overlay to bond both interfaces

Question 5

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.

One branch location is not able to communicate with another branch location via dynamic branch-to-branch tunnels. While troubleshooting at the Edge configuration level, the network administrator notices Cloud VPN is not enabled and is grayed out, preventing them from enabling that feature.

Options:

A.

Where is the next location to check for and enable the necessary feature?

B.

Within the Configuration section under Profiles. Within the Monitor section under Network Services.

C.

Within the Test & Troubleshooting section under Remote Diagnostics.

D.

Within the Configuration section under Customer VPN enablement.

Question 6
