VMware SD-WAN Troubleshoot Questions and Answers

Question 1

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.

Users at a remote office are complaining about poor performance with certain applications. The network administrator has already configured Business Policies based on these requirements.

What is the sequence of parameters that the administrator can check to troubleshoot this problem? (Choose two.)

Options:

A.

Change the bandwidth measurement under WAN Overlay Advanced Settings.

B.

Check underlay network (bandwidth, latency, jitter, packet loss).

C.

Under Monitor, check Routing tab.

D.

Review Business Policies configuration and match them against the business requirements.

Exhibit.

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?

Modify the Keep Alive and Hold timers to the lowest possible values ensuring the Hold timer is 3 times more than the Keep Alive timer.

B.

Nothing, the system will auto-rebalance connections and will provide sub-second convergence.

C.

Modify the Connect and Hold timers to the lowest possible values ensuring the Hold timer is 3 times more than the Connect timer.

D.

Modify the Keep Alive and Hold timers to the lowest possible values ensuring the Keep Alive timer is 3 times more than the Hold timer.

Question 3

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?

Options:

A.

The activation link did not specify the updated image location requiring the Edge to be re-activated.

B.

The activation link did not contain any post-activation configuration to allow the Orchestrator to communicate with the Edge.

C.

The Edge will be offline for about 4 hours until it has completed the factory image installation.

D.

The activation link contained incorrect configurations for WAN overlays and WAN interfaces.

Question 4

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.

What is a possible reason for this?

Options:

A.

Cloud VPN for the Edges / Profiles is not enabled.

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.

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.

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 6

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?

Options:

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.

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.

Exhibit.

A network engineer is configuring an Internet Backhaul Policy for the Chicago Branch to utilize NY's hub as a much better source for Internet for certain SaaS applications. For an unknown reason, the network engineer is not able to select the hubs in the Internet Backhaul Policy.
