Question1: 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?

Exhibit.

When checking connectivity from the San Jose branch, all users report that they can reach certain resources at the main data center. They are unable to reach locations elsewhere. The network administrator investigates and first looks at the Overlay Flow Control (OFC) Table.
What should the network administrator look for next to determine what the issue might be?

Question3: Scenario 2:
After completing the branch activation activities for ail 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 certconfigurations have been complete. The administrator also observed that several 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 thatall sites can talk to each other and all resources are accessible.
Exhibit.

A network administrator has been told that Dallas needs some high-availability in the event that the SD-WAINJ Edge goes offline for whatever reason. There is limited budget so the administrator must use the other available CE router as a fallback mechanism. The administrator will use VRRP to provide HA. When configuring VRRP, the SD-WAN Edge service restarted.
What caused this behavior?

Question4: 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 thatduring 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 the Dallas Branch are complaining that downloads/uploads from Office365 are slow. Working in Teams has been providing slow responses. The Internet circuit is 100Mbps while the MPLS Circuit is
45Mbps. Upon troubleshooting, the network administrator has noticed the traffic is Backhauling through the Seattle hub for all internet traffic.
How should the network administrator resolve the issue?

Question5: 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?

Question6: Scenario 2:
After completing the branch activation activities for all required branches, the 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 tunnel from the Dallas site to the Seattle hub is not coming up.
What are two things that should be checked to determine the issue? (Choose two.)

Question7: 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?

Question8: 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?

Question9: 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.

A technician has added Edges to an East Coast Profile. These Edges are not able to communicate via dynamic tunnels to Edges in the West_Coast profile. The technician has noticed that some Edges are able to establish dynamic tunnels.
What could be preventing Edges from being able to establish dynamic tunnels?

Question10: 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.
