A data center provider has designed a network using these requirements:
- Two data center sites are connected to the public Internet.
- Both data centers are connected to different Internet providers.
- Both data centers are also directly connected with a private connection for the internal traffic, and public Internet traffic can also be routed at this direct connection.
- The data center provider has only one /19 public IP address block.
Under normal conditions, Internet traffic should be routed directly to the data center where the services are located. When one Internet connection fails, the complete traffic for both data centers should be routed by using the remaining Internet connection. In which two ways can this routing be achieved?
(Choose two.)

You work as a network designer for a company that is replacing their Frame Relay WAN with an MPLS VPN service, where the PE-to-CE routing protocol is BGP. The company has 3000 routes in their distribution routers, and they would like to advertise their access routers through the MPLS network. Their service provider, however, only supports 1000 prefixes per VRF. Which two design solutions can be applied to ensure that your access routers will be able to reach all devices in your network? (Choose two.)

Refer to the exhibit.

What limitations exist in this design, given that the access layer devices are expected to steadily increase by two devices per week for the next year?

A service provider using IS-IS has designed this network with all core links at the Layer 2 control plane.
How will they adjust the design to reduce the flooding of update packets?
