Questions # 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).

Question # 1

Question # 1

What might be disallowing the Edge to communicate with the Orchestrator?

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.

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 lo. 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.

Question # 5

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.

What could be the reason?

Options:

A.

The Dynamic Branch to Branch has not been enabled.


B.

The hub is not configured with the proper IP address.


C.

Dynamic Branch to Branch using gateways has not been enabled.


D.

The Edge's profile does not include Backhaul hubs as an option.

Questions # 6:

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.

Question # 6

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?

Options:

A.

Verify that the NVS feature is enabled in Cloud VPN.


B.

Verify that redistribution between the primary hub site and San Jose is enabled.


C.

Verify the static routes to San Jose from all Branches are configured.


D.

Verify that redistribution at the Dallas Hybrid Site is enabled for San Jose to use as a peering point.

Options:

A.

Check with the local network administrator to see if the routes for the SD-WAN sites are present in San Jose's branch router.


B.

Check Test & Troubleshoot and review a route table dump of the NY hub site.


C.
