Correct answerC

Question 2

Single choice

A customer is using Office 365.

How would the VMware SD-WAN recognize this application correctly?

A
The VCE supports prioritization and QoS. Each application is assigned one of the three Service Classes and three Business Priorities.
B
Top SaaS Apps (TLS encrypted) are identified using put. IP and port ranges Other TLS traffic can be identified based on the certificate information.
C
Office 365 has to be added as part of customizing the Application Map by TCP/UDP port and subnet ranges.
D
VMware SD-WAN will use SSL inspection to detect Office 365.

Question 3

Single choice

A service provider assigns two Partner Gateways to a VMware SD-WAN Edge.
Which description is correct about default route.

A
A default route 0.0.0.0/0 can be configured as a static route and set to NAT only on the Gateway
B
It default route 0 0 0.010 has been configured for both Gateways, internet traffic originated from the Edge can failover to the other Gateway in case of a Gateway failure.
C
When handoff is turned off on a Partner Gateway, the Gateway does not advertise a default route 0.0 0.0/0 to the Edge.
D
The service provider administrator decides whether the Partner Gateway advertises a default route 0.0.0.0/0 or not, although it is advertised by default.

Question 4

Single choice

A network architect is designing a VMware SD-WAN architect for customer using VMware hosted VCO and VCGs, white VCEs will be deployed at the customer's branches and data centers. The network architect would like to achieve control plane redundancy.

Which action, if any, should be taken to meet this goal?

A
Multiple VCGs are automatically assigned to every VCE and control plane on VCUs is always enabled, so control plane redundancy has been taken care of already
B
Multiple VCFs at data centers can be contoured to function as route reflectors to achieve control plane redundancy.
C
VCGs automatically assigned to a VCF. do not participate in control plane At least two dedicated Controllers should be manually assigned for each VCGs to achieve control plane redundancy.
D
VCGs automatically assigned to a VCE do not participate in control plane At least two dedicated Controllers should be manually assigned for the customer to achieve control plane redundancy

Question 5

Single choice

The VMware SD-WAN solution is comprised of Orchestrator, Gateway, and Edge. The architecture ensures separation and secure communication between the management, control, and data plane of the solution.
The management plane consists of the VMware SD-WAN Orchestrator, and the control plane is comprised of the VMware SO-WAN Gateway/ Controller.

Which statement correctly describes this situation?

A
VMware SD-WAN Edges/Gateways establishes a Transport Layer Security (TLS) 1 2 encrypted session to the VMware SU-WAN Orchestrator
B
To make the entire solution to work property, TCP port 443 and HOP port 500 and UDP port 4500 are required to open in the firewall rule, if Edge is deployed behind a Firewall.
C
There is impact on data plane when the Edge loses connectivity to the management plane. The operator only loses the visibility of the Edge from Orchestrator and cannot make configuration changes on the Edge until the management plane connectivity is resumed.
D
Traffic between VMware SD-WAN Edges and from VMware SD-WAN Edges to VMware SD-WAN Gateways uses VMware SD-WAN Management Protocol (VCMP) tunneling over User Datagram Protocol (UDP) port 2427. secured with Internet Protocol Security (IPSec)

Question 6

Single choice

A customer is migrating a branch site with a VMware SD-WAN Edge coexisting with the CE. The Edge will be connected to internet link directly while connecting to the CE via a Layer 3 LAN switch. MPLS underlay is the preferred path for communication from this site to branch sites that have no VMware SD-WAN Edges. Communication from this site to branch sites that have VMware SD-WAN Edges should go through overlay.

A
Use BGP as the rout.ng protocol on UK Edge and flag its BGP neighbor to the Layer 3 LAN switch as Uplink.
B
Use BGP as the routing protocol on the Edge and filter prefixes from CE using Uplink Community
C
Use BGP as the routing protocol on the Edge and flag its HGP neighbor to PE as Uplink.
D
Use BGP as the routine, protocol on the Edge and flag its BGP neighbor to GE as Uplink.

Question 7

Single choice

A service provider needs to upgrade a gateway to a new software version.

Which step in needed to complete the upgrade process?

A
Re-assign the Gateway to a new gateway Pool with the appropriate software version, and then run
`sudo apt-get update'' from the Gateway console.
B
Create a new disk partition to save the new software image to, modify the boot order via the Gateway BIOS to boot to the new partition, and then reboot the gateway.
C
From the Orchestrator, select the check-box next to the appropriate gateway, choose `'Assign Software
image", and then select the version for the upgrade.
D
Copy the new image to/var/lib/velocloud/software_update.tar, and then run the upgrade the script from the console.

A
4 segments
B
2 segments
C
6 segments
D
5 segments
