IPsec Outsourcing

Applied Knowledge Questions

The following questions are designed to test your knowledge of IPsec VPN design practices and might build on knowledge gained elsewhere in the book. You might find that a question has more than one possible answer. The answers provided in Appendix B are intended to reinforce best practices that you can apply in your own networking environment.

1:

If you are building a 15-site VPN network and most of the traffic flows from spoke to hub, but some traffic must flow from spoke to spoke, choosing from mesh, partial mesh, and hub and spoke, which topology should you choose?

2:

In which situations is routing unnecessary in an IPsec VPN?

3:

In its simplest form, how many security associations (SAs) are required to establish bidirectional communication between two IPsec peers?

4:

When might it be appropriate to use an application layer VPN instead of IPsec?

5:

If you have an IPsec VPN deployed for remote users and remote sites, is there any reason you might also deploy SSL/TLS application security?

6:

Why are you able to run transport mode IPsec when you deploy GRE + IPsec?
