The question
Which DMVPN phase introduces NHRP redirect and shortcut switching for spoke-to-spoke traffic?
The answer
C Phase 3
Phase 3 uses NHRP redirects from the hub to trigger shortcut tunnels, letting you summarize routes. Watch out: Phase 2 also does spoke-to-spoke, but completely breaks with summarization.
Exam tip
Read what the question is actually asking before looking at the options. The wrong answers here are ones candidates genuinely pick — each is true of something adjacent, just not of what was asked.
