A service must remain available if a server, power supply, or network switch fails. Which design choice best strengthens its redundancy?
- A
Add another server in the same rack and rely on the existing power supply and network switch.
- B
Place critical components in separate failure domains and identify shared dependencies that could still cause a joint failure.
- C
Replicate all data continuously and treat replication as protection against every kind of data loss.
- D
Keep a standby server but connect it through the same network path as the primary server.

A team wants backups to remain usable if production credentials are compromised. Which protection best supports that goal?
- A
Use production credentials for all backup systems so administrators can access them quickly.

Encrypt backups, restrict access, and separate them from ordinary production credentials and systems.
