OpenDNS is a Cisco security solution designed to protect which component?

  • LAN
  • Cloud
  • WAN
  • DMZ
OpenDNS is a company and service that hosts a cloud computing security product suite, Umbrella. OpenDNS’s business services were renamed as Cisco Umbrella; home products retained the OpenDNS name. It also offers DNS resolution as an alternative to using Internet service providers’ DNS servers or locally installed DNS servers.

Other services offered for cloud protection by Cisco include Cloud lock.

While other products exist for LAN, WAN and DMZ, the Umbrella feature is not one of them.

A local area network (LAN) covers a small geographic area. Typically, a LAN is confined to a campus, a single building, a floor of a building, or an area with in building.

A wide area network (WAN) uses routers (or a collection of routers) to connect LANs that are dispersed over a large geographic area. An example would be a company with office locations in Boston, Miami, Chicago, Dallas, Denver, and San Francisco. Each office has its own LAN, and routers are used to provide connections between the offices. By building the WAN, the offices can share resources and data.
