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)

A customer would like to use a VNF firewall on the VMware SU-WAN 600 series Edge. Where do the Edge firewall rules of the VNF apply?

A. Underlay

B. Overlay

C. WAN side

D. LAN side

During a VMware SD-WAN design session for a core business application, a customer expressed the

following requirements:

Allow business abstraction so that similar policies can be applied across different hardware types.

Eliminate the need for the operations team to know the type of physical connectivity or the WAN carrier.

Maintain SLA for real-time application.

Which design should be taken in terms of Link Steering?

A. Select WAN Link, and then define the DSCP tagging

B. Select Error Correct Before Steering with % definition

C. Select Transport Group, and then select Preferred option.

D. Deselect Error Correct before Steering Defaults.

What are three key benefits of VMware SD-WAN? (Choose three )

A. Provision Edges in minutes

B. Automated configuration of cloud resources

C. Remove requirement of Edge devices

D. Gain visibility across any link

E. Layer 2 VPNs between sites

F. Reduce the burden on MPLS

An enterprise has deployed a VMware SD-WAN solution with Edges in many different located to different

Partner Gateways.

Which design makes it possible to have dynamic branch to branch VPN tunnels between any two Edges?

A. Dedicated at least one Gateway as a Controller, and few initial data plane packets will travers the Controller before dynamic tunnel is established between the two branches.

B. Add Controller role to each Partner Gateway.

C. Configure each partner Gateway as a Controller.

D. Dedicate at least one Gateway as a Controller, and no data plan packets will traverse the Controller before dynamic tunnel is established between the two branches.

During a security-related discussion, an administrator determines that guest users not be able to access

any resources on the corporate network.

Which VMware SD-WAN feature can achieve this goal in the most scalable and manageable way?

A. Segments

B. Business Policy

C. VLANs

D. Firewall

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.

An administrator is looking for a cost effective model of hardware-based Edge for some branch offices. The

device must be mounted in rack cabinet, and to meet performance requirements and projected growth, the

appliance must support up to 2 Gpbs bandwidth.

Which Edge model satisfies these requirements?

A. Edge 3400

B. Edge 540

C. Edge 510

D. Edge 620
