Yourorganization is working on a design solution for a new Internet-based remote access
virtual private network that has 1000 remote sites. A network administrator recommends
GETVPN as the model because the network of today uses DMVPN, which results in a lot of
background NHRP control traffic. What is a potential problem with using GETVPN for this design
solution?

A.
GETVPN would require a high level of background traffic to maintain its IPsec SAs.

B.
GETVPN is not scalable to a large number of remote sites.

C.
GETVPN and DMVPN will not interoperate.

D.
GETVPN key servers would be on public, hacker-reachable space and need higher security.
