An enterprise plans to start using a public cloud service and is considering different WAN options. The answers list four options under consideration. Which options provide good security by keeping the data private while also providing good QoS services? (Choose two answers.)
- Using private WAN connections directly to the cloud provider
- Using an Internet connection without VPN
- Using an intercloud exchange
- Using an Internet connection with VPN
Explanation: Private WAN options use technologies like Ethernet WAN and MPLS, both of which keep data private by their nature and which include QoS services. 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.
For the two incorrect answers, both use the Internet, so both cannot provide QoS services. The Internet VPN option does encrypt the data to keep it private.
