MPLS is a standards-approved technology for speeding up network traffic flow and making it easier to manage. Two MPLS service providers (SP1 and SP2) are offering inter-provider RFC 2547/4364-based IP- VPN service to an enterprise customer. IP traffic among some of the customer's sites has to traverse both of the service providers. The service providers and the enterprise do not know what the minimum MTU is along the end-to-end path.
How to guarantee that large packets are not dropped for MTU-related reasons?

You are designing a network solution to connect a primary data center to a disaster recovery site. The applications hosted on the site will be mainly web and email servers that are provided through a virtualized environment. A third data center facility may also be added in the next six months. Which connectivity type is appropriate for this design?

Refer to the exhibit.

When designing an MPLS-based LAN extension between DC-1 and DC-2, what are three advantages of deploying VSS? (Choose three.)

Refer to the exhibit.

Refer to the exhibit. You are planning a migration to a dual-stack IPv4/IPv6 campus environment while providing a flexible and scalable design with fault isolation. The design must allow IPv6 devices to tunnel over portions of the campus that are not yet natively IPv6-enabled , including wireless and voice endpoints. You plan requires an interim approach that allows for a faster information of new services without requiring a network wide hot cutover. Which two services block functions meet these requirements? (Choose two)
