Your company plans to start using public cloud service and now you are considering different WAN options. Your main concern is security by keeping the data private while also providing good QoS services. Which of the following options are under consideration? (Choose two answers.)

(A) Using private WAN connections directly to the cloud provider
(B) Using an Internet connection without VPN
(C) Using an Internet connection with VPN
(D) Using an intercloud exchange

A and D are the correct answers.

Private WAN options use technologies like Ethernet WAN and MPLS, both of which keep data private by their nature and which include QoS services. Private WAN use technologies to transmit data between two or more locations, whilst prioritizing private internet traffic and avoiding public network to increase the level of security. Essentially it is a private network that allows a multi-sited business to share information, privately, with their own private internet.

An intercloud exchange is a purpose-built WAN service that connects to enterprises as well as most public cloud providers, using the same kinds of private WAN technology with those same benefits. Intercloud exchange has come to be known as a company that creates a private network as a service. First, an intercloud exchange connects to multiple cloud providers on one side. On the other side, the intercloud connects to cloud consumers. The pros is that you get the same benefits as when connecting with a private WAN connection to a public cloud, and the mi gration to a new cloud provider is easier. The main con is that using an intercloud exchange introduces another company into the mix.
