What is SD-WAN appliance?

An SD-WAN uses a centralized control function to steer traffic securely and intelligently across the WAN and directly to trusted SaaS and IaaS providers. This increases application performance and delivers a high-quality user experience, which increases business productivity and agility and reduces IT costs.

Which model is used for physical router in SD-WAN?

With physical, virtual, and cloud routing options, you can deploy Cisco SD-WAN on Cisco vEdge, Cloud Services Router (CSR) 1000V, 1000 Series Integrated Services Routers (ISRs), and 4000 Series ISRs, and with Network Functions Virtualization (NFV) using Cisco SD-Branch solutions such as the Cisco 5000 Series Enterprise …

What is the purpose of the vBond element in an SD-WAN deployment?

vBond The vBond is part of the orchestration and zero touch deployment of SD-WAN, a vBond tells the vEdge which vSmart will be responsible for its configuration and policies.

What are SD-WAN components?

There are three main components to this virtualized network: The SD-WAN edge, the controller, and the orchestrator. The SD-WAN edge is where the network endpoints reside. This can be a branch office, a remote data center, or cloud platform.

Does SD-WAN require hardware?

In reality, an SD-WAN needs underlying hardware because hardware is the target and transport for all SD-WAN operations. Any traditional WAN service requires hardware at each end of the network to complete the connection, and an SD-WAN sits on top of this connection — it does not replace the connection.

Which of the following are basic SD-WAN features?

Which of the following are basic SD-WAN features? Application-aware routing for best path selection and failover. Centralized management and real-time monitoring. The ability to use multiple WAN connections, like MPLS and broadband internet.

What is Viptela SD-WAN?

The Viptela SD-WAN offering is a segmented network overlay that uses encryption for security, enforces policies locally and from a central location, and can integrate with third party services.

Which two mechanisms can be used with the SD-WAN solution when ensuring branch security?

SD-WAN solutions must have security mechanisms at startup (or initial installation) at the branch office. Bidirectional safe authentication is needed to cover the remote SD-WAN terminator to the central point and back again. There are many different products aimed at resolving this risk and allowing ZTP.

What is vManage vBond vSmart?

As you know vManage is a single dashboard to manage, troubleshoot, configuration and Policy push orchestration layer controller which is connected with vSmart, vBond and vEdges via different connections. Fig 1.1- Cisco SDWAN Viptela (vBond, vSmart & vManage)

What is the purpose of the vBond element?

vBond Orchestrator (or a better word “facilitator”) ensures SD-WAN fabric on-boarding. It holds the information needed to authenticate vEdges that wish to join the fabric and also a list of vSmart Controllers and vManage to pass along to the vEdges (routers).

What happens if vManage goes down?

If the active vManage NMS goes down unexpectedly, or you simulate a vManage going down in a lab environment, restore the most recent copy of the configuration database to the standby vManage NMS. In this scenario, the active vManage(s) NMS goes down, or the data center hosting them goes down.

What is vManage in SD-WAN?

Cisco SD-WAN vManage API is a REST API interface for controlling, configuring, and monitoring the Cisco devices in an overlay network. The following are the usecases for vManage APIs: Monitor device status. Configure a device, such as attaching a template to device. Query and aggregate device statistics.

Which three basic types of SD-WAN deployments are out on the market?

There are three basic types of SD-WAN deployments: Internet-based SD-WANs, Telco and MSP Managed Service SD-WANs, and SD-WAN as-a-Service.

What are the main components of the Cisco SD-WAN solution?

The solution is broken up into four planes: data, control, management and orchestration.

What are necessary components of the controller for the Cisco SD-WAN?

There are four components of SD-WAN as the Cisco SD-WAN architecture is broken up into four planes: data plane, control plane, management plane, and orchestration plane.

What is required for SD-WAN deployment?

An SD-WAN solution must generally provide the following types of functionality: Multiple connection types – MPLS, Internet, LTE, ADSL, etc. Secure site-to-site connectivity – tunneling and VPNs. An intuitive interface for managing WAN connections.

Do you need a firewall with SD-WAN?

With the expanding threat surface, ensuring the safety of branch users and devices when using cloud-based applications has become paramount. A built-in firewall has become a core requirement for SD-WAN, and several SD-WAN solutions offer one.

Is SD-WAN a software?

SD-WAN is a software-defined approach to managing the WAN. Key advantages include: Reducing costs with transport independence across MPLS, 4G/5G LTE, and other connection types.

Which four of the following options are some of the benefits of SD-WAN?

  • Improves performance. Not all network traffic is created equal.
  • Boosts security. Digital transformation is a double-edged sword.
  • Lowers complexity.
  • Enables cloud usage.
  • Reduces costs.

Where is SD-WAN used?

The most common use cases are branch offices, campus networks, metro Ethernet services and enterprises that need quality of service (QoS) for real-time applications. For the most part, networking vendors believe MPLS will be around for a long time and that SD-WAN won’t totally eliminate the need for it.

What is an SD-WAN gateway?

An SD-WAN gateway can insulate cloud applications from interruptions during circuit flapping because the end users are connected to the gateway. This keeps the session active during the interference instead of the session connecting directly to the cloud service.

What is VeloCloud SD-WAN?

The VMware SD-WAN by VeloCloud product features include high performance, high reliability, virtualization of appliances, cloud integration, automation, and easy orchestration. VMware also emphasizes that the product is effective at virtualizing the infrastructure of an enterprise’s branch locations.

What is vEdge vSmart?

vEdge – router which receive complete control and data policies from the vSmart, it is able to run routing protocol like OSPF, BGP to create connectivity on LAN side but also with MPLS provider if necessary. It establishes secure IPSec tunnels with others vEdges depending on selected topology.

Can SD-WAN replace MPLS?

Yes! SD-WAN provides similar performance and reliability to a dedicated MPLS circuit. However, it accomplishes this by aggregating various transport media and optimizing traffic routing rather than relying upon predefined, dedicated links.

Which security features are most common to SD-WAN products?

  1. Security is centralised and scalable. The centralised controller in SD-WAN can set security policies for the entire network.
  2. Prioritising traffic from remote locations.
  3. Zero-touch and segmentation.
  4. Traffic encryption and firewalls.
  5. Connectivity with the cloud.
