A company requests that you consult with them regarding the design of their production, development, and test environments. They indicate that the environments must communicate effectively, but they must be kept separate due to the inherent failures on the development network. What will be configured on the links between the networks to support their design requirements?

A large enterprise company is redesigning their WAN infrastructure and has these design requirements:
The Frame Relay WAN infrastructure will be replaced with an MPLS VPN service.

BGP is the PE-CE routing protocol adopted for this scenario.

There are 3000 routes in the routing database of the distribution routers.

All 3000 routes will be advertised from the access routers through the MPLS network.

The service provider that provides this MPLS VPN service supports only 1000 prefixes per VRF.

Which two design solutions ensure that the enterprise access routers reach all devices in this enterprise network? (Choose two.)

Which two IEEE standards are commonly used at the data link layer for an access network, in an loT environment? (Choose 2)

Refer to the exhibit Assume that no multicast optimization is done on LAN switches A and B Which two solutions can be used to optimize multicast traffic forwarding in this situation? (Choose two )

Refer to the exhibit. Which two design options reduce the size of OSPF database? (Choose two)
