A Company Wants to Connect Two Data Center Sites Using

question 251

Multiple Choice

A company wants to connect two data center sites using a hub-and-spoke design with 2000 remote sites. One design consideration is the requirement to transfer MPLS packets over the public Internet. In addition, one router at each site should be used, and the MPLS packets must be encapsulated inside IP packets because the public Internet cannot transfer native MPLS packets. Which feature can be used to simplify the network design?

• A) GET VPN can be used to encrypt the MPLS packets with IPsec.
• B) DMVPN can be used to build up GRE tunnels dynamically with MPLS encapsulation inside.
• C) L2TPv3 can be used to encapsulate the MPLS packets.
• D) Site-to-site IPsec without GRE can be used to encapsulate the MPLS packets.
• E) PPPoE can be used to encapsulate the MPLS packets.

Definitions:

Vertices

The plural of vertex, referring to the corners or intersecting points of geometric shapes or graphs.

Hyperbola

A type of smooth curve lying in a plane, consisting of two branches, which are mirror images of each other, and asymptotically approaching fixed lines.

Asymptotes

Asymptotes are lines that a graph approaches but never reaches, illustrating behavior towards infinity or certain points within the domain.

Vertices

Vertices are the corner points where two or more lines, edges, or curves meet.
