A. stateful switchover 

B. nonstop forwarding 

C. route processor redundancy 

D. optimized edge routing

Q16. Which statement is the most accurate regarding IPsec VPN design for an Enterprise Campus environment? 

A. VPN device IP addressing must align with the existing Campus addressing scheme. 

B. The choice of a hub-and-spoke or meshed topology ultimately depends on the number of remotes. 

C. Sizing and selection of the IPsec VPN headend devices is most affected by the throughput bandwidth requirements for the remote offices and home worker 

D. Scaling considerations such as headend configuration, routing protocol choice, and topology have the broadest impact on the design. 


Q17. When is a first-hop redundancy protocol needed in the distribution layer?
