Show answer
Answer
- A Uninterruptible power supply in the data center
- C Regular backups with tested restores
- E Load balancing across several servers
Explanation
Availability requires a service to remain usable despite load, failures or data loss. Load balancing, backups and a UPS contribute directly to this. Encryption and pseudonymization protect confidentiality and privacy but do not improve reachability.
