Company XYZ has 30 sites running a legacy private WAN architecture that connects to the Internet via multiple high- speed connections The company is now redesigning their network and must comply with these design requirements :
* Use a private WAN strategy that allows the sites to connect to each other directly and caters for future expansion.
* Use the Internet as the underlay for the private WAN.
* Securely transfer the corporate data over the private WAN.
Which two technologies should be Incorporated into the design of this network? (Choose two.)

• A.S-VTI
• B.IPsec
• C.PPTP
• D.DMVPN
• E.GET VPN

OSPF is running as the IGP to provide reachability to all AS100 networks R3 and R4 are the current ABRs at the boundary of OSPF Area0 and Areal Now BGP must be deployed within AS 100 because it will be receiving Internet routes from its eBGP peers (the service provider) connected to R1 and R2 What is an optimal solution for this deployment to configure BGP relationships and redistribute BGP learned routes into OSPF?

• A.A full mesh should be deployed between all the routers with mutual redistribution to take place at R1 and R2.
• B.R1, R2, R3 and R4 must be set up with a neighbor relationship with R5 only must not be a route reflector.
• C.R5 should be configured as a route reflector for R1, R2, R3 and R4. BGP routes must be redistributed at R1 and R2 into OSPF.
• D.Configuration should be set up with R1 and R2, and R3 in one sub AS, with and R4 in another, and redistribution at R1 and R2.
