Compare PPTP and L2TP.
What will be an ideal response?
While Point-to-Point Tunneling Protocol (PPTP) was designed mainly as a tunneling protocol between a single client and a private LAN, achieved mainly with software, Layer 2 Tunneling Protocol (L2TP) supports many types of connections and has the endpoint exist on a VPN-capable router (a VPN concentrator), working at Layer 2, rather than having an endpoint be a server program. While PPTP has authentication and encryption, L2TP has no authentication or encryption built in, and relies on other protocols, such as IPSec, for security.

How might page migration and page replication actually reduce system performance?
a) Page replication requires a more complex coherency protocol because the same page can exist at separate nodes. b) Replicating or migrating a page is more costly than remotely referencing a page a small number of times. If pages that are replicated or migrated are not referenced again at their new nodes, then these strategies slow average memory access time. c) The information that must be maintained to make good migration and replication decisions can consume substantial memory overhead. d) all of the above
