Select all that apply. Every correct option and no extras are required for credit in the app.

A.Test the actual application routes, DNS, and firewall policies over the backup path
B.Verify backup bandwidth can sustain the surviving production load
C.Add a second diagram line without changing route preference
D.Assume tunnel Connected status proves all application paths and capacity
E.Disable TLS because reachability requires plaintext

✓ Correct answers

Test the actual application routes, DNS, and firewall policies over the backup path
Verify backup bandwidth can sustain the surviving production load

Backup readiness includes usable capacity and complete application routing, DNS, and security behavior. Tunnel status alone does not validate those, a diagram does not establish a working path, and failover does not require removing application confidentiality. Source guide: PDF page(s) 57.
