Question 1
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 in this
environment as well. Please refer to the topology.
Exhibit.
One of the Edges at the Chicago site is unable to activate. The Edge has a red LED. What is the next
troubleshooting step?
- A. If the Edge is connected to its HA peer, determine if there is a link-light on the HA peer-link.
- B. If the Edge is connected to the MPLS circuit, determine if the Hub is advertising gateway routes.
- C. If the Edge is connected to the MPLS circuit which does not have DHCP, determine if there is a static IP configuration that needs to be applied upon activation.
- D. If the Edge is connected to its HA peer, determine if underlay BGP peering is present between the two Edges.
Answer:
C
Question 2
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

Question 3
Scenario 2:
After completing the branch activation for all required branches, the network administrator attempts
to test connectivity between the various branches and between 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 some 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.
